为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图1是本申请实施例适用的一种通信系统的示意图。车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的，车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地，基站110可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
图2是本申请实施例适用的另一种通信系统的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地，车载终端可以随机选取传输资源，或者通过侦听的方式选取传输资源。
需要说明的是，在侧行通信中，根据进行通信的终端所处的网络覆盖情况，可以分为网络覆盖内侧行通信，如图3所示；部分网络覆盖侧行通信，如图4所示；及网络覆盖外侧行通信，如图5所示。
图3：在网络覆盖内侧行通信中，所有进行侧行通信的终端均处于基站的覆盖范围内，从而，上述终端均可以通过接收基站的配置信令，基于相同的侧行配置进行侧行通信。
图4：在部分网络覆盖侧行通信情况下，部分进行侧行通信的终端位于基站的覆盖范围内，这部分终端能够接收到基站的配置信令，而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端，无法接收基站的配置信令，在这种情况下，网络覆盖范围外的终端将根据预配置(pre-configuration)信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH)中携带的信息确定侧行配置，进行侧行通信。
图5：对于网络覆盖外侧行通信，所有进行侧行通信的终端均位于网络覆盖范围外，所有终端均根据预配置(pre-configuration)信息确定侧行配置进行侧行通信。
图6：对于有中央控制节点的侧行通信，多个终端构成一个通信组，该通信组内具有中央控制节点，又可以称为组头终端(Cluster Header，CH)，该中央控制节点具有以下功能之一：负责通信组的建立；组成员的加入、离开；进行资源协调，为其他终端分配侧行传输资源，接收其他终端的侧行反馈信息；与其他通信组进行资源协调等功能。
需要说明的是，设备到设备通信是基于终端到终端(Device to Device，D2D)的一种侧行链路(Sidelink，SL)传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，因此具有更高的频谱效率以及更低的传输时延，车联网系统采用终端到终端直接通信的方式。在3GPP定义了两种传输模式，分别记为：第一模式(sidelink resource allocation mode 1)和第二模式(sidelink resource allocation mode 2)。
第一模式：终端的传输资源是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。如图3所示，终端位于网络覆盖范围内，网络为终端分配侧行传输使用的传输资源。
第二模式：终端在资源池中选取一个资源进行数据的传输。如图5所示，终端位于小区覆盖范围外，终端在预配置的资源池中自主选取传输资源进行侧行传输；或者，如图3所示，终端在网络配置的资源池中自主选取传输资源进行侧行传输。
在新空口-车辆到其他设备(New Radio-Vehicle to Everything，NR-V2X)中，支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X中，支持广播传输方式，在NR-V2X中，引入了单播和组播的传输方式。对于单播传输，其接收端终端只有一个终端，如图7所示，UE1、UE2之间进行单播传输；对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端，如图8所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1发送数据，该组内的其他终端设备都是接收端终端；对于广播传输方式，其接收端是发送端终端周围的任意一个终端，如图9所示，UE1是发送端终端，其周围的其他终端，UE2-UE6都是接收端终端。
为便于更好的理解本申请实施例，对本申请相关的NR-V2X系统帧结构进行说明。
NR-V2X中的时隙结构图10所示，图10中的(a)表示时隙中不包括物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)的时隙结构；图10中的图(b)表示包括PSFCH的时隙结构。
NR-V2X中物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)在时域上从该时隙的第二个侧行符号开始，占用2个或3个正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号，在频域上可以占用{10,12 15,20,25}个物理资源块(physical resource block，PRB)。为了降低UE对PSCCH的盲检测的复杂度，在一个资源池内只允许配置一个PSCCH符号的数量和PRB的数量。另外，因为子信道为NR-V2X中物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)资源分配的最小粒度，PSCCH占用的PRB的数量必须小于或等于资源池内一个子信道中包含的PRB的数量，以免对PSSCH资源选择或分配造成额外的限制。PSSCH在时域上也是从该时隙的第二个侧行符号开始，该时隙中的最后一个时域符号为保护间隔(Guard Period，GP)符号，其余符号映射PSSCH。该时隙中的第一个侧行符号是第二个侧行符号的重复，通常接收端终端将第一个侧行符号用作自动增益控制(Auto gain control，AGC)符号，该符号上的数据通常不用于数据解调。PSSCH在频域上占据M个子信道，每个子信道包括N个连续的PRB。如图10中的(a)所示。
当时隙中包含PSFCH信道时，该时隙中倒数第二个符号和倒数第三个符号用作PSFCH信道传输，并且倒数第三个符号上的数据是倒数第二个符号上数据的重复，在PSFCH信道之前的一个时域符号用作GP符号，如图10中的(b)所示。
为便于更好的理解本申请实施例，对本申请相关的侧行(Sidelink，SL)CSI-RS进行说明。
NR-V2X中支持SL CSI-RS，SL CSI-RS可以在满足以下3个条件时发送：
UE发送对应的PSSCH，也就是说，UE不能只发送SL CSI-RS；
高层信令激活了侧行信道状态信息(Channel State Information，CSI)上报；
在高层信令激活了侧行CSI上报的情况下，UE发送的第二阶SCI中的相应比特指示了侧行CSI上报。
SL CSI-RS支持的最大端口数为2，当SL CSI-RS为两端口发送时，每个端口上的SL CSI-RS占用同一个OFDM符号的相邻两个资源元素(Resource Element，RE)，两个端口上的SL CSI-RS占用相同的RE，通过码分的方式区分两个端口的资源。在一个PRB内每个端口的SL CSI-RS的个数为1，即密度为1。所以，在一个PRB内SL CSI-RS最多只会出现在一个正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号上，这个OFDM符号的具体位置由发送端终端确定。SL CSI-RS所在的OFDM符号的位置由PC5-无线资源控制(Radio Resource Control，RRC)中的侧行CSI-RS第一个符号(sl-CSI-RS-FirstSymbol)参数指示。
SL CSI-RS在一个PRB内占用的第一个RE的位置由PC5-RRC中的侧行CSI-RS频域分配(sl-CSI-RS-FreqAllocation)参数指示，如果SL CSI-RS为一个端口，该参数为长度为12的比特位图，对应一个PRB内的12个RE。如果SL CSI-RS为两个端口，该参数为长度为6的比特位图，在这种情况下SL CSI-RS占用2f(1)2f(1)和2f(1)+1两个RE，其中f(1)表示值为1的比特在上述比特位图中的索引。SL CSI-RS的频域位置也是由发送终端确定，但是确定的SL CSI-RS的频域位置不能和相位跟踪参考信号(Phase Tracking Reference Signal，PT-RS)发生冲突。图11给出了一种SL CSI-RS时频位置示意图，在图11中，SL CSI-RS端口数为2，sl-CSI-RS-FirstSymbol为8，sl-CSI-RS-FreqAllocation为[b 5,b 4,b 3,b 2,b 1,b 0]＝[0,0,0,1,0,0]，也即，f(1)＝2，2f(1)＝4和2f(1)+1＝5，SL CSI-RS占用RE#4和RE#5。
为便于更好的理解本申请实施例，对本申请相关的多波束系统进行说明。
NR或5G系统的设计目标包括高频段(例如6GHz以上的频段)的大带宽通信。当工作频率变高时，传输过程中的路径损耗会增大，从而影响高频系统的覆盖能力。为了能够有效地保证高频段NR系统的覆盖，一种有效的技术方案便是基于大规模天线阵列(Massive MIMO)，以形成增益更大的赋形波束，克服传播损耗，确保系统覆盖。
毫米波天线阵列，由于波长更短，天线阵子间距以及孔径更小，可以让更多的物理天线阵子集成在一个有限大小的二维天线阵列中，同时，由于毫米波天线阵列的尺寸有限，从硬件复杂度、成本开销以及功耗等因素考虑，无法采用数字波束赋形方式，而是通常采用模拟波束赋形方式，在增强网络覆盖同时，也可以降低设备的实现复杂度。
一个小区(扇区)使用一个较宽的波束(beam)来覆盖整个小区。因此在每个时刻，小区覆盖范围内终端设备都有机会获得系统分配的传输资源。
NR/5G的多波束(Multi-beam)系统通过不同的beam来覆盖整个小区，即每个beam覆盖一个较小的范围，通过时间上的扫描(sweeping)来实现多个beam覆盖整个小区的效果。
图12示出了不使用波束赋形和使用波束赋形系统的示意图。图12中的(a)是传统的、不使用波束赋形的LTE和NR系统，图12中的(b)是使用波束赋形的NR系统：
在图12中的(a)中，LTE/NR网络侧使用一个宽的波束来覆盖整个小区，用户1-5在任何时刻都可以接收到网络信号。
与此相反，图12中的(b)中网络侧使用较窄的波束(例如图中的波束1-4)，在不同的时刻使用不同波束来覆盖小区中的不同区域，例如在时刻1，NR网络侧通过波束1覆盖用户1所在的区域；在时刻2，NR网络侧通过波束2覆盖用户2所在的区域；在时刻3，NR网络侧通过波束3覆盖用户3和用户4所在的区域；在时刻4，NR网络侧通过波束4覆盖用户5所在的区域。
图12中的(b)中，由于网络使用较窄的波束，发射能量可以更集中，因此可以覆盖更远的距离；同时由于波束较窄，每个波束只能覆盖小区中的部分区域，因此模拟波束赋形是“以时间换空间”。
模拟波束赋形不仅可以用于网络侧设备，也同样可以用于终端。同时，模拟波束赋形不仅可以用于信号的发送(称为发送波束)，同样也可以用于信号的接收(称为接收波束)。
不同的波束(beam)通过上面承载的不同信号来进行识别。
一些不同波束(beam)上传输不同的同步信号块(Synchronization Signal block，SS block)，终端设备可以通过不同的SS block来分辨出不同的波束(beam)。
一些不同的波束(beam)上传输不同的信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，终端设备通过CSI-RS信号/CSI-RS资源来识别出不同的波束(beam)。
在一个多波束(multi-beam)系统中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)可以通过不同的下行发送波束来传输。
对于载频在6GHz以下系统，终端侧一般没有模拟波束，因此采用全向天线(或者接近全向的天线)来接收基站不同下行发送波束发送的信号。
对于毫米波系统，终端侧可能会有模拟波束，需要使用对应的下行接收波束去接收对应的下行发送波束发送的信号。此时，需要相应的波束指示信息(beam indication)来协助终端设备确定网络侧的发送波束相关信息，或者终端侧对应的接收波束相关信息。
在NR协议中，波束指示信息不是直接指示波束本身，而是通过信号之间的准共址(Quasi-co-located，QCL)假设(如QCL类型为“QCL-TypeD”的QCL假设)来进行指示。在终端侧，确定接收相应的信道/信号的统计特性，也是基于QCL准共址假设。
为便于更好的理解本申请实施例，对本申请相关的下行传输的QCL准共址指示/假设进行说明。
终端在进行信号接收时，为了提高接收性能，可以利用数据传输所对应的传输环境的特性来改进接收算法。例如可以利用信道的统计特性来优化信道估计器的设计和参数。在NR系统中，数据传输所对应的这些特性通过QCL状态(QCL-Info)来表示。
下行传输如果来自不同的传输接收点(Transmission Reception Point，TRP)/天线阵列块(panel)/波束(beam)，则数据传输所对应的传输环境的特性可能也会有变化，因此在NR系统中，网络侧在传输下行控制信道或数据信道，会通过传输配置指示(Transmission Configuration Indicator，TCI)状态将对应的QCL状态信息指示给终端。
一个TCI状态可以包含如下配置：
TCI状态标识(ID)，用于标识一个TCI状态；
QCL信息1；
QCL信息2(可选)。
其中，一个QCL信息又包含如下信息：
QCL类型(type)配置，可以是QCL-TypeA，QCL-TypeB，QCL-TypeC或QCL-TypeD中的一个；
QCL参考信号配置，包括参考信号所在的小区标识(ID)，带宽部分(Band Width Part，BWP)标识(ID)以及参考信号的标识(可以是CSI-RS资源标识或同步信号块索引)。
其中，如果QCL信息1和QCL信息2都配置了，至少一个QCL信息的QCL类型必须为QCL-TypeA，QCL-TypeB，QCL-TypeC中的一个，另一个QCL信息的QCL类型必须为QCL-Type D。
其中，不同QCL类型配置的定义如下：
'QCL-TypeA':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread),平均时延(average delay)，延时扩展(delay spread)}；
'QCL-TypeB':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread)}；
'QCL-TypeC':{多普勒频移(Doppler shift),平均时延(average delay)}；
'QCL-TypeD':{空间接收参数(Spatial Rx parameter)}。
在NR系统中，网络侧可以为下行信号或下行信道指示相应的TCI状态。
如果网络侧通过TCI状态配置目标下行信道或目标下行信号的QCL参考信号为参考SSB或参考CSI-RS资源，且QCL类型配置为TypeA，TypeB或TypeC，则终端可以假设该目标下行信号与该参考SSB或参考CSI-RS资源的大尺度参数是相同的，该大尺度参数通过QCL类型配置来确定。
类似的，如果网络侧通过TCI状态配置目标下行信道或下行信号的QCL参考信号为参考SSB或参考CSI-RS资源，且QCL类型配置为TypeD，则终端可以采用与接收该参考SSB或参考CSI-RS资源相同的接收波束(即Spatial Rx parameter)，来接收所述目标下行信道或目标下行信号。通常的，目标下行信道(或下行信号)与它的参考SSB或参考CSI-RS资源在网络侧由同一个TRP或者同一个panel或者相同的波束来发送。如果两个下行信号或下行信道的传输TRP或传输panel或发送波束不同，通常会配置不同的TCI状态。
对于下行控制信道，可以通过无线资源控制(Radio Resource Control，RRC)信令或者RRC信令+媒体接入控制(Media Access Control，MAC)信令的方式来指示对应控制资源集(Control Resource Set，CORESET)的TCI状态。
对于下行数据信道，可用的TCI状态集合通过RRC信令来指示，并通过MAC层信令来激活其中部分TCI状态，最后通过下行控制信息(Downlink Control Information，DCI)中的TCI状态指示域从激活的TCI状态中指示一个或两个TCI状态，用于所述DCI调度的PDSCH。2个TCI状态的情 况主要是针对多个TRP类似的场景。例如，如图13所示，网络设备通过RRC信令指示N个候选的TCI状态，并通过MAC信令激活K个TCI状态，最后通过DCI中的TCI状态指示域从激活的TCI状态中指示1个或2个使用的TCI状态。
为便于更好的理解本申请实施例，对本申请存在的技术问题进行说明。
在SL系统中，如果接收端支持利用接收波束进行侧行接收，需要考虑如下问题1至问题3。
问题1：在SL系统中，支持单播、组播、广播等传输方式，接收端终端在同一时刻需要接收周围多个终端发送的侧行数据，当终端采用基于波束的发送或接收时，通常采用模拟波束，即终端在同一时刻只能支持一个发送波束或一个接收波束。此时终端很难在同一时刻用一个接收波束接收所有周围终端发送的侧行数据。
问题2：若终端支持发送波束，在确定发送端最优发送波束的过程中，通常采用如下的方式，发送端使用不同的波束轮流发送CSI-RS，不同的发送波束对应不同的CSI-RS资源，接收端使用相同的接收波束分别接收发送端发送的多个CSI-RS，并且对检测到的CSI-RS进行测量，选取具有最优测量结果的CSI-RS资源并将其对应的资源信息(如CSI-RS资源索引)反馈给发送端，该CSI-RS资源对应的发送波束即是对接收端最优的发送波束。发送端根据接收端反馈的CSI-RS资源向接收端配置TCI状态，接收端根据TCI状态关联的参考信号即可确定相应的接收波束和/或发送端使用的发送波束，并且利用该接收波束进行接收。
问题3：若终端支持接收波束，需要确定最优的接收波束，在确定接收波束的过程中，发送端使用相同的发送波束发送CSI-RS，接收端用不同的接收波束分别接收CSI-RS，并进行测量，基于测量结果选取最优的接收波束。但是若发送端是基于自主选取的方式获取传输资源(即上述第二模式)，接收端很难提前获知发送端的传输资源，并且发送端的传输资源也可能被其他终端抢占，因此需要引入特殊的机制进行接收波束的选取，该特殊的机制例如，发送端发送的用于接收端确定接收波束的CSI-RS资源不能被其他终端抢占，或者引入新的CSI-RS结构。
由上可见，若接收端支持基于波束的传输，上述3个问题都是需要解决的问题。另外，若终端具有波束对应(beam correspondence)能力，则终端可以基于接收波束确定发送波束，此时可以简化确定发送波束的过程。
基于上述问题，本申请提出了一种侧行传输方案，发送端设备获取接收端设备的能力信息，如是否支持接收波束、是否具有波束对应性等，发送端设备根据接收端设备的能力信息执行相应的波束选取或波束指示等过程。
需要说明的是，本申请实施例中的波束在未作说明的情况下，可以指的是发送波束和/或接收波束；波束可以通过波束赋形(beamforming)或者空域滤波形成；空域滤波可以通过空域滤波器(spatial domain filter)实现。波束赋形与空域滤波可以作同一理解，或者一个波束与一个空域滤波器对应；发送波束赋形与空域发送滤波可以作同一理解，或者发送波束与空域发送滤波器(spatial domain transmission filter)对应；接收波束赋形与空域接收滤波可以作同一理解，或者，接收波束与空域接收滤波器(spatial domain reception filter)对应。在一些实施例中，空域发送滤波器可以称为空域传输滤波器。在一些实施例中，空域接收滤波器又称为定向空域接收滤波器。
以下通过具体实施例详述本申请的技术方案。
图14是根据本申请实施例的无线通信的方法200的示意性流程图，如图14所示，该无线通信的方法200可以包括如下内容中的至少部分内容：
S210，第一终端设备获取第一信息和/或第二信息；其中，该第一信息用于指示第二终端设备是否支持空域接收滤波器；该第二信息用于指示该第二终端设备是否支持波束对应性，或者，该第二信息用于指示该第二终端设备是否具有波束对应能力；
S220，第二终端设备发送第一信息和/或第二信息；其中，该第一信息用于指示该第二终端设备是否支持空域接收滤波器；该第二信息用于指示该第二终端设备是否支持波束对应性，或者，该第二信息用于指示该第二终端设备是否具有波束对应能力。
在本申请实施例中，该第一终端设备为发送端设备，该第二终端设备为接收端设备。
在一些实施例中，空域发送滤波器(spatial domain transmission filter)也可以称为发送波束(transmissionbeam)或者空间关系(Spatial relation)或者空间配置(spatial setting)或者空间发送参数(SpatialTXparameter)。
在一些实施例中，空域接收滤波器(spatial domain receive filter)也可以称为接收波束(receptionbeam)或者空间接收参数(SpatialRXparameter)。
在一些实施例中，空域发送滤波器和空域接收滤波器统称为空域滤波器，空域发送滤波器也可以称为发送端空域滤波器，空域接收滤波器也可以称为接收端空域滤波器或接收波束。
在一些实施例中，该第一终端设备可以通过该第二终端设备获取该第一信息和/或该第二信息。
在一些实施例中，该第一终端设备也可以通过预配置信息或协议约定信息获取该第一信息和/或该第二信息。
在一些实施例中，该第一终端设备还可以通过网络设备获取该第一信息和/或该第二信息。
例如，在侧行带宽部分(SLBWP)配置信息或资源池配置信息中包括指示信息，该指示信息用于指示是否支持空域接收滤波器。若该指示信息指示不支持空域接收滤波器，则所有的终端都不支持空域接收滤波器，即不采用空域接收滤波器进行侧行数据的接收。
例如，在侧行带宽部分(SLBWP)配置信息或资源池配置信息中包括指示信息，该指示信息用于指示是否支持波束对应性。若该指示信息指示支持波束对应性，则终端可以基于空域接收滤波器确定空域发送滤波器，或者基于空域发送滤波器确定空域接收滤波器。
在侧行系统中，如果采用波束的方式进行数据的传输，在发送端设备需要确定最优的发送波束，和/或，在接收端设备需要确定最优的接收波束，在上述确定波束的过程中，发送端设备需要发送侧行CSI-RS。
在一些实施例中，在确定发送端设备的最优发送波束的过程中，如图15所示，发送端设备可以使用不同的波束轮流发送CSI-RS，不同的发送波束对应不同的CSI-RS资源，接收端设备使用相同的接收波束分别接收发送端设备发送的多个CSI-RS，并且对检测到的CSI-RS进行测量，选取具有最优测量结果的CSI-RS资源并将其对应的资源信息(如CSI-RS资源索引)反馈给发送端设备，该CSI-RS资源对应的发送波束即是对接收端最优的发送波束。
在一些实施例中，接收端设备向发送端设备上报或反馈N个CSI-RS资源信息及其对应的测量结果，发送端设备在该N个CSI-RS资源中选取一个CSI-RS，并用其对应的发送波束进行侧行传输。当接收端设备向发送端设备反馈N个CSI-RS资源时，发送端设备可以认为该N个CSI-RS资源对应的发送波束都是可用的发送波束。发送端设备从该N个CSI-RS资源中选取一个CSI-RS资源作为目标CSI-RS资源(例如，选取最优测量结果对应的CSI-RS资源)，并将该CSI-RS资源对应的波束作为目标发送波束，发送端设备利用该目标发送波束向接收端发送侧行数据，并将该目标CSI-RS资源告知接收端设备，如指示TCI状态，该TCI状态的参考信号为该目标CSI-RS资源，QCL类型为QCL-TypeD。接收端设备根据TCI状态获知该目标CSI-RS资源，即可使用与接收该CSI-RS资源时相同的接收波束接收发送端发送的侧行数据。如果发送端设备可以判断波束失效，则发送端设备会重新选取发送波束。可选的，发送端设备可以从该N个CSI-RS资源中选取除上述目标CSI-RS资源之外的其他的CSI-RS资源作为新的目标CSI-RS资源，并将其对应的发送波束作为新的目标发送波束，利用该新的目标发送波束进行侧行传输。
应理解，在确定空域发送滤波器的过程中，发送端设备使用不同的空域发送滤波器轮流发送CSI-RS，包括发送端设备发送的每个CSI-RS都对应不同的空域发送滤波器，或者，发送端设备不是使用相同的空域发送滤波器发送CSI-RS，本申请对此不做限定。
