Abstract

Systems and methods are disclosed that use carrier aggregation to provide measurement gaps for UEs to account for switching times for transmitting sounding reference signals. The UE sends a UE-EUTRA-Capability IE to the eNB in RRC signaling indicating UL and DL outage times within the band pair during RF retuning for switching between band pairs to send SRS. The interruption time is represented in OFDM symbols. When the UE is configured to use autonomous gaps for neighbor cell measurements and there is a collision between the autonomous gap measurements and SRS transmissions, the SRS transmissions are skipped when the autonomous gap measurements have priority, and some or all of the autonomous gap measurements are skipped when the SRS transmissions have priority.

Carrier wave polymerization (CA) is introduced in LTE- advanced (LTE-A) to increase the bandwidth communicated between eNB and UE, to increase Add bit rate.Each component carrier (CC) is initially designed in Release8/9, has the up to bandwidth of 20MHz and five most CC polymerization, this increases to 32 CC in Release13.In some TDD embodiments, the bandwidth of the quantity of CC and each CC Downlink (DL) and uplink (UL) can be identical.In other TDD embodiments, due to heavier downlink chain Road business load, so the quantity of DL CC can be more than uplink CC.DL and UL CC can be different, and can be Or it can not be continuous.

As described above, introducing SRS so that eNB can determine channel quality by using the reference signal transmitted by UE. It can be switched in different uplink carriers using SRS, it is mutual with the channel for obtaining desired amount from all uplink measurements Easy gain.However, RF chain can switch between different frequency during SRS switching.This may cause the UL/DL communication of UE It interrupts, and may correspondingly change the present communications process between UE and eNB.

In order to eliminate the problem caused by interrupting by caused by SRS switching, increase SRS protective time slot.Since SRS switches institute The timing being related to, so about 500 μ s can be can achieve with RF tuning period and be changed by being designed as the subframe of protective time slot.Example Such as, this can depend on the configuration (for example, FDD or TDD and frame structure) in each CC.It can be indicated by UE to network communication It interrupts.In addition to RF chain retune associated tuning period other than, interruption can also include relevant to time advance Time.Time relevant to time advance can indicate the timing off-set between the uplink at UE and downlink wireless frame (Nta) and both fixed time sequence advance offsets (Nta_offset), both of which is in 3GPP technical specification (TS) 36.211 It is defined in clause 3.1.

Fig. 7 shows the timing diagram that UE in accordance with some embodiments is retuned between carrier component (CC).UE and eNB can To be one of element described in Fig. 1 to Fig. 6.For convenience, several relevant sub-frames of each of a pair of of CC are only shown (SF).TDD (and FDD) UL/DL configuration in Fig. 7 in other figures define in 3GPP TS 36.211.Fig. 7 shows UE UL and DL SF at the eNB connected with UE.CC1 710 and CC2 720 are provided by same eNB.The SF shown can be for example The SF#5-8 of frame.

In Fig. 7, UE transmission (Tx) time sequence difference between CC1 710 and CC2 720 is not reflected.As shown, such as Fruit RF tuning period is 500 μ s and UE is intended to send SRS at UL SF#n+1 on CC2 720, then Transmission CC2 Subsequent down link pilot timeslot (DwPts) 724 and uplink pilot time slot (UpPts) 726 and CC1 710 on 720 With a part of the DL SF#n in 720 the two of CC2.This occurs to be greater than DwPts 724 and UpPts 726 in the switching period 722 When.In this case, network (eNB and other network elements) is it is known that switching the period 722 and therefore cannot use CC1 DL SF#n+1 on 710 and the UpPts on CC2 720 cannot be received.Similarly, UE is known that the DL on CC1 710 SF#n+1, and a part of DwPts 724 and DL SF#n cannot be received on CC2 720, and possibly can not be in CC2 UpPts 726 is sent on 720.Even if network, which may attempt to minimize to interrupt, to be influenced, network and UE still can coordinate the performance To avoid the mistake scheduling or resource/power dissipation in transmission attempt.Accordingly, it may be desirable to which network knows the definite RF tuning of UE Time (switching period).

Fig. 8 shows the timing diagram that UE in accordance with some embodiments is retuned between CC.As described above, in UE and eNB Each can be one of element described in Fig. 1 to Fig. 6.Fig. 8 shows 810 He of CC1 at the eNB that UE and UE are connected UL the and DL SF of CC2 820.

As described above, eNB and UE are known that RF tuning period, it may include switching period 812 and Nta+Nta_ offset 814.This can permit the quantity for the SF that UE and eNB determines that the switching period 812 is overlapped.In fig. 8, switch the period 812 + Nta+Nta_offset 814 is greater than 1ms.In this case, UE possibly can not be received on CC1 810 DL SF#n+1 with And the tail portion (for example, the last one or two symbols) of DL SF#n is received on CC1 810.The performance of UE and eNB can be with It is greater than according to switching period 812 and Nta+Nta_offset 814 and is also less than 1ms and changes.

Fig. 9 shows the timing diagram that UE in accordance with some embodiments is retuned between CC.As described above, in UE and eNB Each can be one of element described in Fig. 1 to Fig. 6.Fig. 9 shows 910 He of CC1 at the eNB that UE and UE are connected UL the and DL SF of CC2 920.Different from the timing diagram of Fig. 8 and Fig. 9, in Fig. 9, CC1 910 and CC2 920 be can be used not With communication plan operate；Particularly, FDD communication plan can be used to operate in CC1 910, and CC2 920 can be used TDD communication plan operates.

As shown in figure 9, UE can by RF chain from CC2 920 be tuned to another TDD CC, and retune and can influence The FDD CC 910 of UE.If Nta+Nta_offset 912 is greater than the switching period 922, only the one of DL SF#n on CC1 910 It part can be Chong Die with the switching period 922；Otherwise, the initial part of the tail portion of DL SF#n and DL SF#n+1 can with cut Change the overlapping of period 922.As described above, the influence in order to determine SRS transmission, and so that it is determined that both eNB and UE to it is corresponding when Sequence performance, both eNB and UE can determine that (Nta+Nta_offset) 912 is greater than and also be less than the switching period 922.

In each embodiment shown in Fig. 7 to Fig. 9, UE can determine the difference of injection time between CC before communication occurs It is different.The information can be supplied to eNB (such as RRC information transmitting) from UE in the control information.This can permit UE and eNB and uses Timing difference determines mode that UE and eNB will be showed.Based on the example in above-mentioned figure, the UL for the CC being switched to immediately in UE One or two subframe before subframe can be Chong Die with RF tuning period, or the UL or DL subframe of the CC immediately in UE switching certainly One or two subframe later can be Chong Die with RF tuning period.The SRS protective time slot at UE can be defined or interrupted with right Quasi- UE and eNB performance.In various embodiments, RF tuning period is depended on, UE can ignore one of DL subframe or DL subframe Divide to guarantee that the entire UL SF in target carrier is transmitted.

Various options can be used to indicate the break period of network.UE can signal one or more to eNB Different values.For example, UE can signal the exact numerical values recited of RF tuning period with some minimum particle sizes to eNB.Most granule Degree can be such as OFDM symbol or part OFDM symbol (for example, 0.5 OFDM symbol).Alternatively or additionally, UE can be with Whether the amount of signaling (RF tuning period+Nta+Nta_offset) is greater than (or whether quantity is less than) SF duration. In some embodiments, the SF duration can be 1ms.Alternatively or additionally, UE can signal RF tuning period Whether (or whether RF tuning period is less than) Nta+Nta_offset is greater than.It can be by using RRC signaling or in-band signaling Carry out completion report, uses MAC control element (CE) or PDCP Packet Data Unit (PDU) etc..In the previous case, UE RF tuning period initially can be being transmitted to during eNB registration, for example, via UE-EUTRA-Capability information element (IE)。

In some embodiments, eNB can send pre-scheduling request to UE.It can one or more before SRS transmission A SF sends pre-scheduling request.In response, UE can send the instruction of the quantity of the subframe influenced by SRS transmission.ENB is subsequent Can determine finally to dispatch will be used to send SRS on target CC to configure which subframe.Pre-scheduling request can indicate that SRS will Which sent on UL SF.Dedicated signaling, such as RRC signaling can be used in eNB, or broadcast signaling can be used and (be such as System block of information (SIB)) it is requested to transmit pre-scheduling.

In some embodiments, SRS can be limited to be arranged in UL subframe and the last symbol of UpPts.Figure 10 shows The timing diagram that UE in accordance with some embodiments is retuned between CC out.As described above, each of UE and eNB can be One of element described in Fig. 1 to Fig. 6.Figure 10 shows the UL of CC1 1010 and CC2 1020 at the eNB that UE and UE are connected With DL SF.

As shown in Figure 10, the switching period 1022 in CC2 1020 can with the tail portion of DL SF#n, DwPts and The initial part of UpPts is overlapped.SRS symbol 1024 is sent in the last symbol of the UpPts of CC2 1020.Note that not having There is the UE Tx time sequence difference between reflection CC1 and CC2.In the embodiment shown in fig. 10, RF tuning period is 500 μ s.Cause This, RF tuning period 1022 can interrupt a part of the DL SF#n on DwPts and both CC1 and CC2 subsequent on CC2.

Therefore, RRCConnectionRequest message (for example) in by UE notice RF tuning period eNB can It cannot be used for sending UE for DL data with the DL SF#n+1 determined on CC1.UE can be similarly determined in UE cannot be on CC1 It receives DL SF#n+1 and a part of DwPts and DL SF#n cannot be received on CC2, and cannot be sent on CC2 UpPts.Even if eNB, which deliberately attempts to minimize to interrupt, to be influenced, it is also possible to need to know the performance of eNB and UE to avoid mistake scheduling With resource/power dissipation；Therefore, the definite RF tuning period (switching period) of UE can be provided to eNB.

Figure 11 shows the timing diagram that UE in accordance with some embodiments is retuned between CC.As described above, in UE and eNB Each can be one of element described in Fig. 1 to Fig. 6.Figure 11 shows the CC1 1110 at the eNB that UE and UE are connected With UL the and DL SF of CC2 1120.

In Figure 11, UE is configurable on CC2 1120 send SRS symbol 1122 in UL SF#n+2.Therefore UE RF tuning can be completed before the last symbol of UL SF#n+2 on CC2 1120.Here, total time can be defined For normal OFDM symbol length (the last one of UL SF#n+2 of RF tuning period 1122+ (Nta+Nta_offset) 1124+ OFDM symbol) 1126.If total time is greater than sub-frame duration (for example, 1ms), the DL SF#n+1 on CC1 1110 It can be Chong Die with total time with the DL SF#n+2 on CC2 1120；Otherwise only have the DL SF#n+2 on CC1 that can be overlapped.Cause This, eNB and UE can determine which SF is influenced by SRS transmission based on the length (compared with the SF duration) of total time.

Based on the typical case in Figure 10 and Figure 11, immediately in the CC (CC that UE is switched to) being switched to SRS symbol it One or two preceding SF can be Chong Die with RF tuning period, or the CC CC (CC of UE switching certainly) immediately in switching certainly One or two subframe after UL or DL SF can be Chong Die with RF tuning period.For this purpose, the SRS protection at UE can be defined Period interrupts to be directed at UE and eNB performance.The SF that SRS protective time slot is arranged can be different according to total time.As described above, ENB can send pre-scheduling request before sending SRS symbol.

In operation 1202, handover information can be reported from UE to network (eNB or another network entity).Handover information can To include the numerical value with the RF tuning period of minimum particle size x, wherein the unit of x can be Ts (for example, 2048Ts) or 66.7 μ S or OFDM proper symbol length.Alternately or in addition, UE individual bit indicator can be used report (RF tuning period+ Whether summation Nta+Nta_offset) is greater than SF duration (for example, 1ms).Alternately or in addition, list can be used in UE A bit indicator reports whether RF tuning period is greater than (Nta+Nta_offset).Alternately or in addition, UE can make (the OFDM symbol length that RF tuning period+Nta+Nta_offset+ is used for SRS transmission) is reported with individual bit indicator Whether summation is greater than SF duration (for example, 1ms).The band of RRC signaling or such as MAC CE or PDCP PDU can be used in UE Interior signaling reports some or all of above- mentioned information.In some embodiments,

In operation 1204, UE can receive pre-scheduling request from eNB.It can be in the one or more before SRS transmission Subframe receives pre-scheduling request.Pre-scheduling request also can indicate that SRS will be sent on which UL SF.ENB can be used UE's Dedicated signaling, such as RRC signaling, or broadcast signaling (such as SIB) can be used to send pre-scheduling request.

In operation 1206, UE can influence instruction in information in SF and be passed before the UL SF for SRS transmission by SRS The quantity of the subframe of defeated influence.NB then can determine finally to dispatch based on the information that UE is provided, which matches UE It sets in the subframe that will send SRS on target CC.Final scheduling can be received the decode at UE.

In operation 1208, UE may determine whether to measure from during main gap.UE can be to eNB instruction pair The support from main gap in UECapabilityInformation IE.From during main gap, UE stops serving cell Communication with execute measurement or read neighboring community MIB/SIB.It can be used for reading the cell global mark of cell from main gap Know (CGI) information.UE the instruction that whether use from main gap can be received from eNB again.

If not using eNB, UE can simply execute SRS transmission in operation 1218.SRS transmission can be based on upper State space period.

When there is conflict in timing between the two processes, networking rule is depended on, in the switching based on SRS carrier wave It can be different in the process using autonomous clearance measurement and the UE of SRS transmission performance.In operation 1210, UE (can make When with from main gap) determine whether clash between autonomous clearance measurement and SRS transmission.

When the conflict occurs, UE performance can depend on the priority between autonomous clearance measurement and SRS transmission.Therefore, In operation 1212, UE can determine which has priority.As set forth above, it is possible to via the specific signaling of UE, (such as RRC believes Enable) or cell or the specific signaling of eNB (such as SIB) information is provided.

In operation 1214, UE can be paid the utmost attention to based on the measurement from main gap.UE, which can be executed, to be based on from main gap Measurement, and if SRS transmission from the measurement of main gap in the time domain and based on clashing, UE can skip SRS load Wave switching and SRS transmission.It can be the RSRP and/or RSRQ of the neighboring community for example identified based on the measurement from main gap.

If UE pays the utmost attention to SRS transmission in operation 1212, then UE executes SRS transmission in operation 1218.If SRS transmission from the measurement of main gap in the time domain and based on conflicting, then UE can skip the part based on the measurement from main gap Or all.Thus, for example, if SRS transmission with it is completely overlapped based on the measurement from main gap, UE can be skipped completely and is based on From the measurement of main gap, and if SRS transmission is only partially Chong Die with based on the measurement from main gap, UE can merely skip base It executes in the lap of the measurement from main gap, and within remaining time based on the measurement from main gap.Part measurement can Only to include one in RSRP and RSRQ measurement, measurement is restricted to the particular channel of neighboring community, or only read adjacent The MIB (or SIB) of cell, or will measurement be restricted to entirely based on the group measured from the measurement of main gap compared with it is smaller Predetermined neighboring community's group.It can change for the UE operation based on the measurement from main gap are as follows:

T_{identify_CGI}=T_{basic_identiiy_CGI}+T_margin

For in frequency and inter-frequency measurements.If UE is configured to have in identification from the new of the E-UTRA cell of main gap Switch SRS carrier wave or SRS transmission during CGI on some TDD carrier waves, then value T_marginIt is to be caused by the switching based on SRS carrier wave Time delay.

For measuring in frequency, the explicit neighbor list of the new CGI of E-UTRA cell for identification can not be provided to UE, Because neighboring community uses same frequency.On the contrary, UE can be identified in network request and be reported as by from eNB CGI indicated by reportCGI IE.It can be received in DL according to the clause 5.5.3.1, UE of TS36.331 and be built in UL transmission Stand for receive MIB and SIB1 message from main gap.Note that if the si-RequestForHO IE from eNB is set Be it is false, then UE can be to avoid using from main gap.

If measured using from main gap, (DRX) or eDRX CONN are discontinuously received whether or not using, or Whether person configures SCell, and UE can identify the new CGI of E-UTRA cell in following formula:

T_{identify_CGI,intra}=T_{basic_identify_CGI,intra}+T_{margin_intra}

Wherein, T_{basic_identify_CGi,intra}=150ms.The period is used in above-mentioned equation, and there is defined UE identifications The maximum allowable time of the new CGI of E-UTRA cell, condition are that E-UTRA cell is identified by UE.T_{margin_intra}=x ms, Wherein x is non-negative value, for example, 10 or 20 or 40 or 50 or other numerical value.If UE is configured to the only SRS in not PUSCH SRS is sent on component carrier, then be by switching and/or secondary cell (SCell) based on SRS carrier wave not PUSCH only Time delay caused by the SRS transmission carried out on SRS TDD component carrier.UE can have at main plot (PCell) It is sent, or can be sent on the TDD CC of not PUSCH on PCell on the TDD CC of PUSCH.Otherwise, If without configuration SRS transmission, T on the component carrier of the only SRS of not PUSCH_{margin_intra}=0ms.

Similarly, for inter-frequency measurements, the explicit neighbour of the new CGI of E-UTRA cell for identification can not be provided to UE List is occupied, because neighboring community uses same frequency.On the contrary, UE can be identified in network request and be reported such as by from eNB ReportCGI IE indicated by CGI.It can be in DL reception and UL transmission according to the clause 5.5.3.1, UE of TS 36.331 Establish for receive MIB and SIB1 message from main gap.Note that if the si-RequestForHO IE from eNB is set It is set to vacation, then UE can be to avoid using from main gap.

T_{identify_CGI,inter}=T_{basic_identify_CGI,inter}+T_{margin_inter}

Wherein, T_{basic_identify_CGi,inter}=150ms.The period is used in above-mentioned equation, and there is defined UE identifications The maximum allowable time of the new CGI of E-UTRA cell, condition are that E-UTRA cell is identified by UE.T_{margin_inter}=x ms, Wherein x is non-negative value, for example, 10 or 20 or 40 or 50 or other numerical value.If UE is configured to the only SRS in not PUSCH SRS is sent on component carrier, then is enterprising by the switching based on SRS carrier wave and/or in the only SRS component carrier of not PUSCH Time delay caused by capable SRS transmission.Otherwise, if do not configured on the component carrier of the only SRS of not PUSCH SRS transmission, then T_{margin_inter}=0ms.

Therefore, in frequency and both inter-frequency measurements may have identical characteristic, such as timing.In other embodiments In, recognition time etc. can be different.

In some cases, using from main gap, but can there is no the conflicts between main gap and SRS transmission. In such a case, it is possible to execute autonomous clearance measurement by UE in operation 1216.Then SRS can be carried out in operation 1218 Transmission.

Therefore, can be greater than in the TDD embodiment of uplink CC in the quantity of DL CC, TDD CC can not have It is operated in the downlink in the case where PUCCH/PUSCH.UE can allow SRS to exist configured with the SRS switching between CC It is sent on the TDD CC for not having PUCCH/PUSCH.When sending such SRS on the TDD CC in not PUCCH/PUSCH, UE SRS can be sent on TDD CC according to the priority orders of the operation switched of the SRS between CC or skip on TDD CC SRS transmission.
