Description

一种数据复用和数据解析方法、装置及系统 技术领域
本申请涉及无线通信技术领域，尤其涉及一种数据复用和解析方法、装置及系统。
背景技术
随着通信需求的增长和通信技术的发展，未来的通信系统相对于LTE(Long Term Evolution，长期演进)系统，将会采用更高的载波频率，如39GHz等，以实现更大带宽、更高传输速率的无线通信。
由于载波频率大幅提高，载波波长变短，无线信号的衍射、散射能力下降，使其在空间传播过程中经历更加严重的衰落，进而使得基站的覆盖能力受限，甚至在接收端难以检测到发射的无线信号。为此，未来的通信系统将采用波束赋形(beamforming)技术来获得具有良好方向性的波束，以提高在发射方向上的功率，从而改善接收端的信干噪比(Signal to Interference plus Noise Ratio,SINR)。为了增加覆盖范围和控制天线阵列成本，混合波束赋形(Hybrid beamforming)成为一种选择，它同时包含了基带的数字波束赋形(Digital beamforming)和射频端的模拟波束赋形(Analog beamforming)。
如图1所示，当基站在进行波束扫描时，正在扫描的波束可能无法覆盖终端。相反，如果基站没有进行波束扫描，服务于终端的波束会指向终端，在该波束中可以发送的CSI-RS用于CSI测量。
发明人在创造本申请技术方案的过程中发现，CSI-RS在承担CSI测量的功能的时候资源利用率极低。

具体实施方式
为进一步描述本申请，首先，对本申请实施例涉及到的相关技术作简单介绍。
为了获得更大的传输带宽、更快的传输速率等特性，下一代通信系统中将使用相对长期演进技术(LTE，Long Term Evolution)更高的载波频率。
高频通信需要通过波束扫描来实现基站侧和用户侧的波束配对，从而保证有较好的通信质量。图2给出了一种CSI-RS用于波束测量的导频图案的示例，它在连续的OFDM符号10和OFDM符号11上都映射CSI-RS，每个OFDM符号可以扫描同时发射的最多8个模拟 波束，这里称其为一个波束组。每个模拟波束对应到一个端口，并且各个端口之间采用频分复用或码分复用的方式。如果要支持更多模拟波束的扫描，可以选择更多的OFDM符号用于波束扫描。
发明人发现，在现有技术中，由于在进行波束扫描时，不能保证被调度了数据传输的终端的模拟波束和映射CSI-RS的OFDM符号所使用的模拟波束一致，故在CSI-RS用于波束测量的OFDM符号上，尽管还有闲置资源，但也无法用于终端的数据信号的传输。
在下一代通信系统中，CSI-RS不仅可以用于承担波束测量的功能，而且还可以用于承担对终端进行CSI测量的功能。当CSI-RS用于CSI测量时，则要求被执行CSI测量的终端始终被波束覆盖，因此模拟波束在CSI测量过程中不会发生变化或不会发生较多的变换。在这种情况下，模拟波束所覆盖的范围内的终端可以使用CSI-RS所在OFDM符号上的空闲资源，以提高用户资源的利用效率。
本申请实施例提供的技术方案，可以应用于无线蜂窝网络的各种通信系统，例如：全球移动通信(Global System for Mobile communications，GSM)系统，码分多址(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access Wireless，WCDMA)系统，通用分组无线业务(General Packet Radio Service，GPRS)系统，长期演进(Long Term Evolution，LTE)系统，通用移动通信系统(Universal Mobile Telecommunications System，UMTS)，下一代移动通信系统(例如，5G)等。
如图3所示，本申请实施例提供了一种通信系统100。该通信系统100至少包括至少一个基站(base station，BS)20和多个终端，例如终端1、终端2、终端3，终端4等等。与基站20连接的控制节点60，可以对系统中的资源进行统一调度，可以给终端配置资源，进行资源复用决策，或者干扰协调等。
本申请实施例所指网络侧设备可以包括作为对传统无线电信系统中的对等设备的改进的系统和设备。这种高级或下一代设备可以包含在演进无线通信标准(例如长期演进LTE)中。例如，LTE系统可以包括演进通用陆地无线接入网(E-UTRAN)节点B(eNB)、无线接入点或类似组件，而不是传统的基站。任何此类组件将在本文中被称作eNB，但是应当理解的是，此类组件不一定是eNB。下一代通信系统，将使用“gNB”代替LTE系统的eNB。
具体的，网络侧设备可以是如图3所示的基站20或者控制节点60。
本申请实施例所涉及的基站，如图3所示的基站20等，它是一种部署在无线接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)，在第三代(3rd generation，3G)系统中，称为节点B(Node B)等。为方便描述，本申请所有实施例中，上述为终端提供无线通信功能的装置统称为基站或BS。
本申请实施例中所涉及到的控制节点，如图3所示通信系统中的控制节点60，其可以 连接多个基站，并为多个基站覆盖下的多个终端配置资源。例如，基站可以为UMTS系统中的Node B，控制节点可以为网络控制器。又例如，基站可以为小站，则控制节点可以为覆盖小站的宏基站。再例如，控制节点可以为无线网络跨制式协同控制器等，基站为无线网络中的基站，在本申请实施例中不作限定说明。
本申请实施例中所涉及到的终端，如图3所示的通信系统100中的终端1、终端2、终端3等，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述终端也可以称为移动台(mobile station，简称MS)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication,MTC)终端等。为方便描述，本申请所有实施例中，上面提到的设备统称为终端。
本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
图4示意了本申请实施例的终端与网络侧设备之间进行数据复用的结构示意图。
本申请实施例提供的终端，包括：收发器10和处理器11，该终端还可以包括存储器12，其存储计算机执行指令；系统总线13，该系统总线13连接处理器11，收发器10和存储器12等。网络侧设备包括收发器20和处理器21，该网络侧设备还可以包括存储器22，其存储计算机执行指令；系统总线23，该系统总线23连接处理器21，收发器20和存储器22等。
一种实现方式中，网络侧设备的收发器20通过天线向终端的收发器10发送数据信号、CSI-RS和相应的CSI-RS复用指示信息。终端的收发器11通过天线接收来自网络侧设备的收发器20发送的数据信号、CSI-RS和相应CSI-RS复用指示信息，根据该CSI-RS复用指示信息，在所述CSI-RS复用指示信息指示的正交频分复用OFDM符号上解析所述数据信号，并与该OFDM符号所在的传输时隙里的数据信号一起进行解调，其中，在所述OFDM符号上所述数据信号与所述CSI-RS进行了频分复用。这里的传输时隙通常是指的进行数据调制和解调的一个时间单元，通常可以是一个TTI(transmission time interval，传输时间间隔)。
或者在另一种实现方式中，网络侧设备的收发器20通过天线向终端的收发器10发送传输时隙里所有的CSI-RS的模拟波束信息和用于数据传输的模拟波束的信息；
终端的收发器10接收上述传输时隙里所有的CSI-RS的模拟波束信息和用于数据传输的模拟波束的信息，终端的处理器11判断是否存在某个CSI-RS的模拟波束和传输终端的数据信号的模拟波束相同；若是，终端的处理器11则判断该CSI-RS所在OFDM符号上映射有数据信号。进一步的，终端的处理器11在映射有数据信号的OFDM符号上解析数据信号。若否，终端的处理器11则判断该CSI-RS所在OFDM符号上未映射有数据信号。
需要说明的是：终端的处理器11和网络侧设备的处理器21可以是中央处理器(central processing unit，简称CPU)，网络处理器(network processor，简称NP)或者CPU和NP的组合。处理器还可以进一步包括硬件芯片。上述硬件芯片可以是专用集成电路(application-specific integrated circuit，简称ASIC)，可编程逻辑器件(programmable logic device，简称PLD)或其组合。上述PLD可以是复杂可编程逻辑器件(complex programmable logic device，简称CPLD)，现场可编程逻辑门阵列(field-programmable gate array，简称FPGA)，通用阵列逻辑(generic array logic，简称GAL)或其任意组合。
终端的存储器12和网络侧设备的存储器22可以包括易失性存储器(volatile memory)，例如随机存取内存(random access memory，简称RAM)；还可以包括非易失性存储器(non-volatile memory)，例如快闪存储器(flash memory)，硬盘(hard disk drive，简称HDD)或固态硬盘(solid-state drive，简称SSD)；存储器还可以包括上述种类的存储器的组合。
本申请基于CSI-SI复用指示信息实现CSI-RS与数据信号的复用，具体方案如图5所示，结合图4，本申请实施例的数据复用方法如下：
第一步，网络侧设备的处理器21根据实际应用场景或者CSI-RS的功能，以及CSI-RS所在OFDM符号的资源使用情况，判断是否需要将终端的数据信号和CSI-RS进行频分复用，以及在哪些OFDM符号上进行复用，然后进行CSI-RS复用指示信息的配置。
具体的，有如下几种情况：
1、当CSI-RS用于对某个模拟波束覆盖的终端进行信道状态测量，且CSI-RS所在OFDM符号存在空闲资源时，网络侧设备的处理器21确定将终端的数据信号与CSI-RS进行频分复用；
2、当CSI-RS用于对某个模拟波束覆盖的终端进行信道状态测量，但其所在OFDM符号不存在空闲资源时，网络侧设备的处理器21确定终端的数据信号不与CSI-RS进行频分复用；
3、当CSI-RS用于波束测量时，网络侧设备的处理器21确定终端的数据信号不与所述CSI-RS进行频分复用。
第二步，根据配置的CSI-RS复用指示信息的内容，网络侧设备侧的处理器21进行数据和导频OFDM符号之间的资源映射。
第三步，网络侧设备的收发器20根据CSI-RS复用指示信息配置方式的不同，选择合适的方式通知终端，以便终端能正确完成解资源映射。例如：通过L1/L2/L3信令承载CSI-RS复用指示信息，或者其他方式。
第四步，终端的收发器10接收CSI-RS复用指示信息，其处理器11根据该CSI-RS复用指示信息进行解资源映射。
上述第一步中，网络侧设备的处理器21配置CSI-RS复用指示信息，有如下几种实现方式：
1、如果所有OFDM符号上的CSI-RS都与终端的数据信号进行频分复用时，则网络侧设备的处理器21将CSI-RS复用指示信息配置用于指示该所有OFDM符号已频分复用；
2、如果所有OFDM符号上的CSI-RS都不与终端的数据信号进行频分复用时，则网络侧设备的处理器21将CSI-RS复用指示信息配置用于指示该所有OFDM符号未频分复 用；
3、如果部分OFDM符号上的CSI-RS与终端的数据信号进行频分复用时，则网络侧设备的处理器21将CSI-RS复用指示信息配置用于分别指示每个OFDM符号是否频分复用；
4、如果部分OFDM符号上的CSI-RS与终端的数据信号进行频分复用时，则网络侧设备的处理器21将CSI-RS复用指示信息配置用于指示已频分复用的OFDM符号；或指示信息配置用于指示未频分复用的OFDM符号。
下面详细描述本申请实施例中网络侧设备配置CSI-RS复用指示信息以及发送给终端的几种实现过程。
实施例一：
为了灵活地指示CSI-RS与终端的数据信号进行复用的情况，网络侧设备的收发器20可以通过L1/L2信令来承载该CSI-RS复用指示信息。
如果所有OFDM符号上的CSI-RS与终端的数据信号都同时复用或者不复用，那么网络侧设备的处理器21可在下行控制信息(Downlink control information，DCI)中选取1bit资源来标记该信息，0表示不复用，1表示复用；或者0表示不复用，1表示不复用。
如果不同OFDM符号上的CSI-RS与终端的数据信号不同时复用，那么网络侧设备的处理器21可以为每一个CSI-RS所在的OFDM符号配置1bit指示信息，独立指示是否将CSI-RS与终端的数据信号进行复用。
图6给出了一种CSI-RS复用指示信息的实际应用方案。其中，该OFDM符号包括解调参考信号(demodulation reference signal，DMRS)所在的OFDM符号部分，数据信号所在的OFDM符号部分，物理下行控制信道(Physical Downlink Control Channel，PDCCH)所在的OFDM符号部分，CSI-RS所在的OFDM符号部分。CSI-RS复用指示信息通过DCI承载，终端的处理器11通过解PDCCH获得CSI-RS复用指示信息。
应理解的是，此处网络侧设备用DCI信令承载CSI-RS复用指示信息仅为举例，在其他的实现方式中，还可以通过L2信令，例如MAC CE(medium access control control element，媒体接入控制控制元素)信令承载。
实施例二
当在多个OFDM符号上都映射CSI-RS，但只有部分OFDM符号上不和终端的数据信号进行频分复用时，网络侧设备的处理器21可以通过只指示部分CSI-RS和用户数据复用的信息，来减少指示信息的开销。具体指示方法包括：
1、网络侧设备的处理器21确定只指示没有映射数据信号的OFDM符号，其收发器20通过DCI直接通知终端在哪些OFDM符号上没有映射数据信号；
2、网络侧设备的处理器21确定只指示有映射数据信号的OFDM符号，其收发器20通过DCI直接通知终端在哪些OFDM符号上映射了数据信号。
图7示意了用DCI指示多个OFDM符号上进行CSI-RS复用的示意图。在DCI信息中，只需指示被复用的OFDM符号，其余CSI-RS所在OFDM符号则默认为不复用的。 或者，DCI中只需要指示不被复用的OFDM符号，其余CSI-RS所在OFDM符号则默认为被复用的OFDM符号。通常来讲，如果被复用的OFDM符号多则指示未被复用的OFDM符号，如果未被复用的OFDM符号多，则指示被复用的OFDM符号，以达到节约指示信息开销的目的。
实施例三
在一些应用场景中，某些终端可能长时间处于某种相同状态下，此时需要通过L3信令，例如无线资源控制(Radio Resource Control，RRC)信令来承载CSI-RS复用指示信息，避免增加L1/L2信令开销。比如，终端长时间驻留在某个波束覆盖范围内，且通信质量良好，不需要经常进行波束扫描；或者，终端一直处在高速移动中，可能会频繁地进行波束扫描。
图8给出了一种用RRC信令承载CSI-RS复用指示信息的示意图。网络侧设备的处理器21通过RRC承载CSI-RS复用指示信息并通过其收发器20发送至终端，该RRC信令可以用较长的更新周期，避免频繁的信令开销。
应理解的是，RRC信令仅为举例，其他L3信令只要能实现本申请的技术方案，也可以采用来承载CSI-RS复用指示信息。
实施例四
本实施例中，通过L3信令联合L1/L2信令，实现更加灵活的CSI-RS资源配置(CSI-RS resource settings)和CSI报告配置(CSI report settings)，以满足各种不同CSI测量的需求。本实施例中，CSI-RS复用指示信息在进行CSI-RS资源配置时同时配置，也即包含在CSI-RS资源配置(CSI-RS resource settings)信息或CSI-RS配置(CSI-RS settings)信息或CSI-RS初始配置(CSI-RS initial settings)信息中。CSI-RS复用指示信息由网络侧设备根据当前应用和调度需求，直接指示被频分复用的CSI-RS对应的OFDM符号位置，或者指示没有被复用的OFDM符号位置。具体指示方式如下：
1、网络侧设备的处理器21进行CSI-RS初始配置。在该CSI-RS初始配置中，根据终端的应用场景(如终端在某个波束覆盖范围内，没有发生快速移动)，配置一种默认的复用方式，作为CSI-RS和终端的数据信号在一段较长通信周期内的复用方式。
2、在通信过程中，网络侧设备的处理器21根据终端应用场景的变化，例如终端进入高速移动状态，那么之前关于CSI-RS复用指示信息的设置不再适用。此时，网络侧设备的处理器21更新CSI-RS复用指示信息的设置，由收发器20通过L1/L2信令，通知终端新的CSI-RS复用方式。
图9给出了本实施例的示意图，其中应用场景的变化可以是网络侧设备的处理器21根据终端实时反馈的信道质量进行判断；如果终端能自己判断自己的应用场景，也可以通过收发器10主动上报给网络侧设备进行决策。
在本实施方案中，CSI-RS复用指示信息是CSI-RS配置的一部分，其随着CSI-RS配置一起更新。除了配置灵活外，由于CSI-RS配置还是CSI测量的重要部分，这也便于网络侧设备根据不同应用场景设置CSI-RS的复用方式。
上述实施例一至实施例四描述了网络侧设备进行CSI-RS复用指示信息的配置和采 用不同的信令将其发送到终端的实现方式。而在终端侧，终端收到网络侧设备下发的CSI-RS复用指示信息，再根据该CSI-RS复用指示信息，在与数据信号复用的CSI-RS所在的OFDM符号上去解析数据信号，并与该OFDM符号所在的传输时隙里的数据信号一起进行解调，此为本领域技术人员熟知的技术，在此不再赘述。
在另一种实现方式中，终端可以通过某CSI-RS的模拟波束信息推断是否在CSI-RS所在OFDM符号上映射了数据信号，下面通过实施例五详细描述。
实施例五
本实施例提供的数据复用方法具体过程如图10所示：
步骤100，网络侧设备的收发器20通知终端传输时隙里所有的CSI-RS的模拟波束信息。具体的，网络侧设备的收发器20通过L1/L2/L3信令，比如DCI、MAC CE或RRC信令等，告诉终端传输时隙里的所有CSI-RS的模拟波束信息，该信息可以是模拟波束标识或者CSI-RS资源标识和端口号等，其他能表示CSI-RS的模拟波束的方法也应包括在本申请实施例中。
步骤101，网络侧设备的收发器20通知终端用于数据信号传输的模拟波束信息。具体的，网络侧设备的收发器20在开始数据信号传输之前，用DCI或者RRC等方式通知终端用于数据信号传输的模拟波束信息。
步骤102，终端的收发器10接收到上述CSI-RS的模拟波束信息和用于数据信号传输的模拟波束信息之后，其处理器11判断是否存在某个CSI-RS对应的模拟波束和传输终端的数据信号的模拟波束相同；
步骤103，如果存在，那么终端的处理器11则认为该CSI-RS所在OFDM符号上映射有数据信号；进一步的，终端的处理器11就在该CSI-RS所在OFDM符号上解析数据信号。
步骤104，如果不存在，那么终端的处理器11认为所有CSI-RS所在OFDM符号上都没有数据信号被映射。
图11为通过终端的处理器11通过CSI-RS的模拟波束信息推断复用情况的示意图。其中，用于终端的数据信号传输的模拟波束为波束0。OFDM符号6上的CSI-RS在波束0内发送。OFDM符号12在波束1中发送。此时，网络侧设备让终端在波束1上进行波束测量。由于网络侧设备和终端都不确定波束1是否能够覆盖该终端，故终端认为OFDM符号12上的数据信号和CSI-RS没有频分复用。
另外，在高频通信中，网络侧设备和终端可能会维护多个通信质量较好的波束对的备份列表，以实现更具鲁棒性和可靠性的传输。一个波束对包含了对应的一对发射模拟波束和接收模拟波束的信息。因此，尽管某个CSI-RS对应的发射模拟波束和终端的数据信号传输的模拟波束不相同，但若CSI-RS对应的发射模拟波束，和终端在该时刻对应的接收模拟波束处在波束对的备份列表中，则终端的处理器11也认为数据和CSI-RS是复用的。因此这种情况下，如图12所示，波束1和终端在OFDM符号12上的接收模拟波束配对，也能实现网络侧设备和终端之间的可靠通信。
