Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a sounding reference signal transmission circuit, a method, an apparatus, a terminal, a base station, a device, and a medium.
Background
The fifth generation (5rd generation, 5G) and other networks support the beamforming technology and can directionally transmit to the terminal. For directional transmission, the base station first detects the position of the terminal, the quality of the transmission path, etc., so that the resources of the base station are more accurately allocated to each terminal. The terminal sends a Sounding Reference Signal (SRS) which is one of the ways for the base station to detect the terminal position and channel quality.
Specifically, in a 5G network, when a User Equipment (UE) sends a signal, a baseband signal is generated at a baseband, and then a radio frequency signal is generated through a radio frequency link and sent out through a main set antenna. When the terminal device receives the signal, a corresponding radio frequency receiving link is also provided. In NR, both the network device and the UE can improve communication performance through Multiple Input Multiple Output (MIMO) technology, which is also called multiple dominant set antenna technology. In order to improve the communication quality, a main antenna collecting and transmitting mechanism is introduced. And for better scheduling of data transmission. In 5G, the channel state used for transmission is estimated, and the network device may select an appropriate transmission parameter according to the channel estimation result, which is called channel estimation (channel estimation). The UE may use the sounding reference signal for uplink channel estimation. By combining with the MIMO technology, when the SRS resource supports the SRS main set antenna transmission capability, the terminal equipment can use the SRS resource to carry out SRS transmission and simultaneously carry out channel estimation on a plurality of main set antenna rows. The network device configures the SRS resource to the terminal device according to the radio capability (radio capability) reported when the terminal device accesses the network device. The SRS main set antenna transmission capability may also be referred to as SRS main set antenna selection (antenna selection) capability.
In a 5G terminal, there are usually 4 transmitting and receiving main set antennas, and in the prior art, two DP4T (double pole four throw) switches and two SP2T (single pole double throw) switches are generally provided to realize antenna switching of two SRS transmitting methods of 2T4R and 1T4R, and since four selection switches are required, there are problems of high cost and large insertion loss, which further increases power consumption.

Example 1
The embodiment provides a sounding reference signal transmission circuit, which is arranged in a terminal. As shown in fig. 1, the circuit includes: a first selection switch K1, a second selection switch K2, a first master set antenna ANT0, a second master set antenna ANT1, a third master set antenna ANT2, a fourth master set antenna ANT3, a first TRX module, a second TRX module, a third TRX module, and a fourth TRX module.
Wherein the first selection switch K1 is used to control the first TRX module or the third TRX module to be connected with the first T port of the first main set antenna ANT0, the second main set antenna ANT1 or the second selection switch K2; the second selection switch K2 is used to control the connection of the first T port T1 of the second TRX module, the fourth TRX module or the second selection switch K2 with the third main set antenna ANT2 or the fourth main set antenna ANT 3.
Specifically, the first TRX module and the second TRX module are a master set transceiver module supporting a first frequency band, and the third TRX module and the fourth TRX module are a master set transceiver module supporting a second frequency band. For example, the first frequency band may be an N79(4.4 GHz-4.99 GHz) frequency band, and the second frequency band may be an N78 (3.3-3.8 GHz) frequency band.
In the present embodiment, both the first selection switch K1 and the second selection switch K2 can be implemented by 3P3T (3-pole 3-throw) switches. The 3P3T switch has 3P ports and 3T ports, the P ports are all called Port (polarization) ports, the T ports are all called shoot (Throw ) ports, each T Port can be connected with the corresponding 3P ports respectively.
In this embodiment, as shown in fig. 1, a first T port T1 of the first selector switch K1 is connected to the first TRX module, a second T port T2 is connected to the third TRX module, a first P port P1 is connected to a first T port T1 of the second selector switch K2, a second P port P2 is connected to the first main set antenna ANT0, and a third P port P3 is connected to the second main set antenna ANT 1.
The first T port T1 of the second selector switch K2 is connected to the first P port P1 of the first selector switch K1, the second T port T2 is simultaneously connected to the second TRX module and the fourth TRX module, the second P port P2 is connected to the third main set antenna ANT2, and the third P port P3 is connected to the fourth main set antenna ANT 3. Of course, the second TRX module connection and the fourth TRX module connection may also be connected to the second T port T2 and the third T port T3 of the second selector switch K2, respectively, without being limited thereto.
The circuit of the embodiment can realize two SRS alternate transmission modes of one-transmission four-receiving 1T4R and two-transmission four-receiving 2T4R of the first frequency band and the second frequency band. Under the 2T4R transmission mode, two transceiver modules corresponding to the frequency band simultaneously transmit SRS signals; in the 1T4R transmission mode, one of the two TRX transceiver modules corresponding to the frequency band transmits an SRS signal, and the other does not operate.
For example, when SRS polling based on the first frequency band needs to be realized by the 1T4R method, the first TRX module corresponding to the first frequency band operates, and the second TRX module does not operate. The first T port T1 of the first selector switch K1 is controlled to be sequentially connected with three P ports of the first T port T1, and when the first T port T1 of the first selector switch K1 is connected with the first P port P1 of the first T port T1, the first T port T1 of the second selector switch K2 is controlled to be sequentially connected with the second P port P2 or the third P port P3 of the second selector switch K2, and therefore switching connection between the first TRX module and the first to fourth main set antennas ANT 0-3 is achieved. In this case, the first TRX module transmits a plurality of SRSs, and these SRSs are transmitted to the network side device by turns through different dominant set antennas ANT0 to ANT 3.
When the SRS transmission in turn based on the first frequency band needs to be realized in a 2T4R manner, both the first TRX module and the second TRX module corresponding to the first frequency band operate. By controlling the first T port T1 of the first selector switch K1 to be sequentially connected with the second P port P2 and the third P port P3 thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected with the second P port P2 or the third P port P3 thereof, the switching connection of the first TRX module with the first dominant set antenna ANT0 and the second dominant set antenna ANT1, and the switching connection of the second TRX module with the third dominant set antenna ANT2 and the fourth dominant set antenna ANT3 are realized. In this case, the first TRX module transmits the SRS to the network side device through the first and second TRX master antennas ANT1 in turn, and the second TRX module transmits the SRS to the network side device through the third and fourth TRX master antennas ANT3 in turn.
When the SRS transmission based on the second frequency band needs to be realized in a 1T4R manner, the third TRX module corresponding to the second frequency band operates, and the fourth TRX module does not operate. The switching connection between the third TRX module and the first to fourth main set antennas ANT3 is realized by controlling the second T port T2 of the first selector switch K1 to be sequentially connected to the three P ports thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected to the second P port P2 or the third P port P3 of the second selector switch K2 when the second T port T2 of the first selector switch K1 is connected to the first P port P1 of the second selector switch K2. In this case, the third TRX module transmits multiple SRSs, which are transmitted to the network side device by turns through different main set antennas.
When the SRS transmission in turn based on the second frequency band needs to be realized in a 2T4R manner, both the third TRX module and the fourth TRX module corresponding to the second frequency band operate. By controlling the second T port T2 of the first selector switch K1 to be sequentially connected with the second P port P2 and the third P port P3 thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected with the second P port P2 or the third P port P3 of the second selector switch K2, the switching connection of the third TRX module with the first dominant set antenna ANT0 and the second dominant set antenna ANT1, and the switching connection of the fourth TRX module with the third dominant set antenna ANT2 and the fourth dominant set antenna ANT3 are realized. In this case, the first TRX module transmits the SRS to the network side device through the first and second TRX master antennas ANT1 in turn, and the second TRX module transmits the SRS to the network side device through the third and fourth TRX master antennas ANT3 in turn.
After receiving the SRS, the network side device may determine which transmitting antenna has a better channel state with the network side device according to the signal quality of the SRS, and when the network side device schedules the terminal to receive downlink data, the network side device raises the priority of the antenna having the better channel state, so that the terminal preferentially uses the antenna having the better channel state to receive the downlink data.
As can be seen from the above analysis, the present embodiment can implement two SRS transmission modes, i.e., 2T4R and 1T4R, through two selector switches, and compared with the prior art that adopts two DP4T switches and two SP2T switches, the number of switches is reduced, so that the cost can be reduced, the insertion loss can be reduced, and the power consumption can be reduced. In addition, the invention can be compatible with the first frequency band and the second frequency band, and improves the frequency band application range of the circuit.
Example 2
The present embodiment provides a sounding reference signal transmission method implemented based on the circuit of embodiment 1, which is applicable to a terminal, and as shown in fig. 2, the method includes:
and S11, acquiring a target wheel sending mode.
In this embodiment, the target round transmission mode refers to an SRS round transmission mode that needs to be adopted. For example, the target round emission system may be a 1T4R round emission system or a 2T4R round emission system.
Preferably, the target round sending system is issued to the terminal by the network side device.
S12, when a sounding reference signal based on a first frequency band needs to be transmitted, according to the target round transmission scheme, controlling the first TRX module to be connected to the first antenna, the second antenna, or the first T port T1 of the second selector switch K2 through the first selector switch K1, and controlling the second TRX module or the first T port T1 of the second selector switch K2 to be connected to the third antenna or the fourth antenna through the second selector switch K2, so as to transmit an SRS signal according to the target round transmission scheme.
Specifically, when SRS alternate transmission based on the first frequency band needs to be realized through the 1T4R mode, the first TRX module corresponding to the first frequency band operates, and the second TRX module does not operate. The switching connection between the first TRX module and the first to fourth main set antennas ANT3 is realized by controlling the first T port T1 of the first selector switch K1 to be sequentially connected to the three P ports thereof, and controlling the first T port T1 of the second selector switch K2 to be sequentially connected to the second P port P2 or the third P port P3 of the second selector switch K2 when the first T port T1 of the first selector switch K1 is connected to the first P port P1 thereof. In this case, the first TRX module transmits multiple SRSs, which are transmitted to the network side device by turns through different main set antennas.
When the SRS transmission in turn based on the first frequency band needs to be realized in a 2T4R manner, both the first TRX module and the second TRX module corresponding to the first frequency band operate. By controlling the first T port T1 of the first selector switch K1 to be sequentially connected with the second P port P2 and the third P port P3 thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected with the second P port P2 or the third P port P3 thereof, the switching connection of the first TRX module with the first dominant set antenna ANT0 and the second dominant set antenna ANT1, and the switching connection of the second TRX module with the third dominant set antenna ANT2 and the fourth dominant set antenna ANT3 are realized. In this case, the first TRX module transmits the SRS to the network side device through the first and second TRX master antennas ANT1 in turn, and the second TRX module transmits the SRS to the network side device through the third and fourth TRX master antennas ANT3 in turn.
S13, when a sounding reference signal based on a second frequency band needs to be transmitted, according to the target round transmission scheme, the first selector switch K1 is used to control the third TRX module to be connected to the first antenna, the second antenna, or the first T port T1 of the second selector switch K2, and the second selector switch K2 is used to control the fourth TRX module or the first T port T1 of the second selector switch K2 to be connected to the third antenna or the fourth antenna, so as to transmit an SRS signal according to the target round transmission scheme.
For example, when SRS polling based on the second frequency band needs to be implemented by the 1T4R method, the third TRX module corresponding to the second frequency band operates, and the fourth TRX module does not operate. The switching connection between the third TRX module and the first to fourth main set antennas ANT3 is realized by controlling the second T port T2 of the first selector switch K1 to be sequentially connected to the three P ports thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected to the second P port P2 or the third P port P3 of the second selector switch K2 when the second T port T2 of the first selector switch K1 is connected to the first P port P1 of the second selector switch K2. In this case, the third TRX module transmits multiple SRSs, which are transmitted to the network side device by turns through different main set antennas.
When the SRS transmission in turn based on the second frequency band needs to be realized in a 2T4R manner, both the third TRX module and the fourth TRX module corresponding to the second frequency band operate. By controlling the second T port T2 of the first selector switch K1 to be sequentially connected with the second P port P2 and the third P port P3 thereof, and controlling the second T port T2 of the second selector switch K2 to be sequentially connected with the second P port P2 or the third P port P3 of the second selector switch K2, the switching connection of the third TRX module with the first dominant set antenna ANT0 and the second dominant set antenna ANT1, and the switching connection of the fourth TRX module with the third dominant set antenna ANT2 and the fourth dominant set antenna ANT3 are realized. In this case, the first TRX module transmits the SRS to the network side device through the first and second TRX master antennas ANT1 in turn, and the second TRX module transmits the SRS to the network side device through the third and fourth TRX master antennas ANT3 in turn.
The present embodiment provides an SRS round-robin method implemented based on the circuit of embodiment 1, which can implement two SRS round-robin methods, i.e. 2T4R and 1T4R, through two selector switch selection switches, and compared with a scheme in the prior art that two DP4T switches and two SP2T switches are adopted, the number of switches is reduced, so that the cost can be reduced, the insertion loss can be reduced, and the power consumption can be reduced.
Example 3
When the mobile speed of the mobile terminal is different, the sending speeds of the SRS required by the mobile terminal to meet the beam forming requirement are different. Specifically, the sending speed of the SRS required by the mobile terminal to meet the beamforming requirement is positively correlated with the moving speed of the mobile terminal. That is, when the moving speed of the mobile terminal is fast, the SRS transmission speed required by the mobile terminal to meet the beamforming requirement is fast, and the mobile terminal can perform round transmission in a 2T4R manner; when the moving speed of the mobile terminal is slow, the speed of sending the SRS, which is required by the mobile terminal to meet the beamforming requirement, is low, a good beamforming result can be achieved by using 1T4R, and if 2T4R is used, unnecessary power consumption is wasted. Therefore, in this embodiment, in order to obtain a good beamforming effect, when the SRS is transmitted by using the SRS transmission method corresponding to the moving speed, the SRS transmission speed at least can satisfy the requirement of beamforming by the mobile terminal at the moving speed, but does not cause unnecessary power consumption waste.
In view of this, this embodiment provides a sounding reference signal transmission method, which is suitable for a network device used in cooperation with the terminal described in embodiment 2, and as shown in fig. 3, the method includes:
s21, acquiring the moving speed of the terminal, specifically:
first, a current measured terminal position and a last measured terminal position are obtained. In this embodiment, the terminal may be located by using the existing cell location technology.
And then, acquiring the moving speed of the terminal according to the distance between the current measured terminal position and the last measured terminal position and the time difference between the current measurement and the last measurement.
S22, determining the target wheel sending mode according to the moving speed of the terminal, specifically:
when the moving speed of the terminal reaches a preset speed threshold, determining that a target round sending mode is a 2T4R round sending mode; and when the moving speed of the terminal is less than a preset speed threshold, determining that the target round sending mode is a 1T4R round sending mode.
In this embodiment, the set speed threshold is different according to the quality of signal transmission and reception of the terminal, and the higher the transmission and reception quality level is, the larger the speed threshold is. Specifically, the signal transceiving quality level of the terminal is acquired in advance, and when the transceiving quality is high, the speed threshold is set to be a first threshold (for example, 120km/h), and when the transceiving quality is low, the speed threshold is set to be a second threshold (for example, 30 km/h). It should be understood that the speed threshold is not particularly limited in this embodiment, and may be set as needed.
S23, the target wheel transmission system is sent to the terminal, so that the terminal controls the first selection switch K1 and the second selection switch K2 to execute corresponding actions according to the target wheel transmission system, and SRS signals are sent according to the target wheel transmission system.
According to the method and the device for transmitting the SRS in the power grid, the SRS transmitting mode is determined according to the moving speed of the terminal, so that the requirements of different terminal moving speeds on the SRS transmitting mode can be met flexibly, and unnecessary power consumption waste can not be caused.
