一种通信方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
在车到一切(vehicle to everything，V2X)系统中，终端设备之间可通过PC5接口进行直接通信，使用的通信链路称为侧行链路side-link。在侧行链路上，信道状态信息(chanel state information，CSI)反馈通常使用物理侧行链路共享信道(physical side-link shared channel，PSSCH)。
现有技术中，PSSCH信道资源的频域最小粒度为一个子信道带宽，一般为4RB。而CSI信息的数据量一般较少，可能只有几个或几十个bit。假设使用占用8个符号的PSSCH传输CSI信息，该PSSCH会占用4*12*8＝384个资源单元(resource element，RE)。可以看出，在现有的PSSCH上发送CSI信息，会造成较多的资源浪费。

以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端设备，又可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。所述终端设备可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。例如，终端设备可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的示例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control) 中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。本申请实施例中的终端设备还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。
2)网络设备，是网络中用于将终端设备接入到无线网络的设备。所述网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为无线接入网(radio access network，RAN)节点(或设备)。网络设备可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(5th generation，5G)新无线(new radio，NR)系统中的下一代节点B(next generation node B，gNB)，或者还可以包括传输接收点(transmission reception point，TRP)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或WiFi接入点(access point，AP)等，再或者还可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。再例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)，RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其它实体交换消息。
3)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
请参考图2，为本申请实施例提供的一种通信方法的流程示意图，该方法包括如下的步骤S201至步骤S203：
步骤S201、第一终端设备从第二终端设备接收侧行信道状态信息参考信号。
该侧行信道状态信息参考信号可以为在侧行链路上传输的信道状态信息参考信号(channel state information-reference signal，CSI-RS)。
步骤S202、第一终端设备根据该侧行信道状态信息参考信号确定信道状态信息(channel state information，CSI)。
本申请实施例中，第一终端设备根据侧行信道状态信息参考信号确定信道状态信息可以为，第一终端设备对步骤S201中接收的侧行信道状态信息参考信号进行测量，得到信道状态信息，该信道状态信息包括一项或多项参数，可由第二终端设备配置。
步骤S203、第一终端设备向第二终端设备发送信道状态信息。
本申请实施例中，该信道状态信息承载在第一侧行链路数据信道上，且该第一侧行链路数据信道的带宽小于最小子信道(sub-channel)带宽。示例性的，该第一侧行链路数据信道可以是PSSCH，第一终端设备对第二终端设备发送的侧行CSI-RS进行测量，并在该PSSCH上向第二终端设备发送CSI，具体可包括，第一终端设备将CSI包括的各个信息比特进行信道编码，并添加循环冗余校验(cyclic redundancy check，CRC)，然后进行调制，将调制后的符号逐一映射到PSSCH包括的各个资源单元(resource element，RE)上。
应理解，本申请实施例中的第一侧行链路数据信道与现有的用于承载数据的PSSCH相比，该第一侧行链路数据信道的带宽小于最小子信道带宽。一般来说，通信系统中可预先设定可使用的最小子信道带宽，该最小子信道带宽以子载波为单位，最小子信道带宽可以为q个RB，q为自然数。网络设备可根据该最小子信道带宽来配置数据信道或控制信道的带宽，网络设备调度的数据信道的带宽为最小子信道带宽的整数倍。例如，目前用于数据调度的PSSCH的最小子信道带宽一般为4个资源块(resource block，RB)或者更多，而本申请实施例中用于承载CSI的PSSCH的带宽可小于4个RB，例如可以是1～3个RB。再例如，最小子信道带宽也可以设置为2RB，在这一情形下，本申请实施例中用于承载CSI的PSSCH的带宽可小于2RB，如可以是1RB。再例如，最小子信道带宽也可以设置为3RB，在这一情形下，本申请实施例中用于承载CSI的PSSCH的带宽可小于3RB，如可以是1RB。因此，第一侧行链路数据信道可以称为紧凑的PSSCH(compact PSSCH)。在仅向第二终端设备发送CSI的情况下，第一终端设备使用这种紧凑的PSSCH来承载CSI，能够有效节省系统资源。
在一种可能的设计中，信道状态信息可承载在逻辑信道的媒体访问控制(media access control，MAC)控制单元CE中。
步骤S204、第一终端设备向第二终端设备发送第一控制信息。
该第一控制信息用于指示信道状态信息。该第一控制信息承载在第一侧行链路数据信道对应的第一侧行链路控制信道上。例如，承载CSI的第一侧行链路数据信道为紧凑的PSSCH，第一终端设备可在该紧凑的PSSCH对应的PSCCH上向第二终端设备发送第一控制信息。如此，第二终端设备可通过检测和解析该PSCCH的内容来对PSSCH的内容进行正确解码，从而得到第一终端设备上报的CSI。
需要注意的是，本申请实施例中的第一侧行链路控制信道占用的资源与第一侧行链路数据信道占用的资源存在时域重叠。例如，第一侧行链路控制信道可在第一侧行链路数据信道所占用的时域资源上，与第一侧行链路数据信道进行频分复用。在一种可能的设计中，第一侧行链路控制信道还可分为两级侧行链路控制信道，其中，第二级侧行链路控制信道可与第一侧行链路数据信道在相同的频域资源上进行时分复用，在此基础上，第一级侧行链路控制信道可在第一侧行链路数据信道与第二级侧行链路控制信道占用的所有时域资源上，与第一侧行链路数据信道进行频分复用。
在一种可能的设计中，该第一控制信息中可包括第一终端设备的身份标识和第二终端设备的身份标识。该第一控制信息中还可包括第一终端设备发送的信道状态信息采用的调 制编码方案(modulation and coding scheme，MCS)，以便第二终端设备在接收到该第一控制信息后对信道状态信息进行解码。该第一控制信息中还可包括源节点标识(source node ID)和目的节点标识(destination node ID)。这里，源节点标识是指第一终端设备的标识，目的节点标识是指第二终端设备的标识，表示第一控制信息是由第一终端设备发送给第二终端设备的，以便第二终端设备检测发送给自己的信息。该第一控制信息可以由第一终端设备携带在侧行链路控制信息(sidelink control information，SCI)中发送给第二终端设备，或者也可以通过其他方式发送，本申请并不限定。例如，第一终端设备可向第二终端设备发送CSI上报消息，该CSI上报消息中包括第一控制信息和信道状态信息。
请参阅图3，为本申请实施例提供的一种紧凑的PSSCH的结构示意图。一个时隙(slot)中，紧凑的PSSCH具有一个与该PSSCH对应的、用于指示该PSSCH的PSCCH。该PSCCH具体可分为两部分，也可以理解为该PSCCH包括又可包括两级信道，分别记作第一级PSCCH和第二级PSCCH。其中，第二级PSCCH可与紧凑的PSSCH的带宽相同，也小于最小子信道带宽。第一级PSCCH的带宽可大于紧凑的PSSCH的带宽，但仍小于最小子信道带宽。例如，如图3中所示，第一级PSCCH的带宽可以为2个RB，第二级PSCCH的带宽与紧凑的PSSCH的带宽相同，可以为1个RB。从时域上看，第一级PSCCH占用的时域资源可与，第二级PSSCH以及紧凑的PSSCH占用的时域资源的总和重叠。
紧凑的PSSCH、该PSSCH对应的第一级PSCCH和第二级PSSCH、以及预留空白(GAP)符号共同构成了一个用于上报CSI信息的资源集合，其中，紧凑的PSSCH与该紧凑的PSSCH对应的第二级PSSCH可共同占据时隙中的13个时域符号，该紧凑的PSSCH对应的第一级PSSCH也可占据时隙中的13个时域符号。而且时隙中的第一个符号还可用于自动增益控制(automatic gain control，AGC)。
如图3所示，紧凑的PSSCH、该PSSCH对应的第一级PSCCH和第二级PSCCH、AGC符号和GAP符号共包括14个时域符号，占满了整个时隙。其中，AGC符号用于第二终端设备的接收机控制接收数据的功率，以免接收功率超过最大动态范围造成误码，GAP符号用于帧之间的收发转换，AGC符号和GAP符号各占用一个时域符号。而PSCCH用于指示PSSCH，以便接收方对PSSCH进行正确解码。PSSCH用于承载CSI信息。例如，第二终端设备在接收CSI时，可如图4，先盲检测PSSCH对应的PSCCH，在检出PSCCH后，根据PSCCH与PSSCH之间的对应关系，对PSSCH中承载的CSI信息进行解码。
应理解，图3中所示的紧凑的PSSCH与对应的PSCCH占用的时域符号的数量仅为一种示例，在实际应用中，紧凑的PSSCH与PSCCH占用的时域符号数量之和为12，但PSSCH占用的时域符号数量可大于等于3且小于等于9，相应的PSCCH占用的时域符号的数量可根据PSSCH占用的时域符号数量而定。
请参阅图5，为本申请实施例提供的另一种紧凑的PSSCH的结构示意图。在这种紧凑的PSSCH的结构中，一个时隙内包括紧凑的PSSCH、该紧凑的PSSCH对应的PSCCH、和GAP符号。该紧凑的PSSCH用于承载CSI信息，带宽小于最小子信道带宽，例如可以是1个RB。该紧凑的PSSCH对应的PSCCH用于承载第一控制信息，其带宽可与紧凑的PSSCH的带宽相同，例如也可以是1个RB，而且该紧凑的PSSCH对应的PSCCH占用的时域资源可与紧凑的PSSCH相同。GAP符号各占用一个时域符号，分别用于自动增益控制和帧收发转换。但是由于图5所示的结构中紧凑的PSSCH与该紧凑的PSSCH对应的PSCCH占用的时域资源相同，二者以频分的方式复用，因此，紧凑的PSSCH和紧凑的 PSSCH对应的PSCCH均占据一个时隙中的13个时域符号，其中该时隙的第一个符号还可用于自动增益控制AGC。
请参阅图6，为本申请实施例提供的一种MAC控制单元(control element，CE)的结构示意图，该MAC CE用于承载信道状态信息CSI。该用于承载CSI消息的MAC协议数据单元(protocol data unit，PUD)由一个MAC头部(header)和一个CSI MAC CE组成。MAC header中含有逻辑信道标识(logical channel ID，LCID)，固定为3比特。该CSI MAC CE的大小为固定16比特，其中含有5或9比特的CSI反馈消息。
请参阅图7，为本申请实施例提供的一种专用资源池的结构示意图，该专用资源池(dedicated resource pool)用于CSI反馈，可以理解为，该专用资源池仅用于发送信道状态信息。本申请中定义的CSI反馈专用PSSCH位于这些资源池中，即第一侧行链路数据信道和第一侧行链路控制信道使用专用资源池内的资源。
在UE所使用的带宽部分(bandwidth part，BWP)中，专用资源池体现为其中的一部分连续/非连续时频资源(图7所示为连续的)。专用资源池的资源调度粒度为子信道，带宽为2～3RB专用资源池中含有且只含有一系列发送CSI反馈的时频资源单元，每个单元的时频资源中含有一个compact format PSSCH和对应的PSCCH。
UE在发送CSI反馈时，如果有数据需要同时发送，则使用数据资源池中的PSSCH发送数据和CSI反馈；如果没有数据需要同时发送，则使用CSI专用资源池中的PSSCH仅发送CSI反馈。
本申请实施例中，如图8中的步骤S200所示，第一终端设备还可从第二终端设备接收侧行信道状态信息配置信息，即侧行CSI config。该侧行信道状态信息配置信息用于指示或触发第一终端设备根据接收到的侧行信道状态信息参考信号，发送信道状态信息。该侧行信道状态信息配置信息可以由第二终端设备携带在侧行链路控制信息(sidelink control information，SCI)中发送给第二终端设备，或者也可以通过单独的侧链无线资源控制(radio resource control，RRC)信令或其他方式发送，本申请并不限定。而且承载该侧行信道状态信息配置信息的PSCCH可以不与PSSCH复用，单独发送。
在一种可能的设计中，侧行信道状态信息配置信息可包括测量侧行信道状态信息参考信号的时域粒度和/或频域粒度、以及信道状态信息包括的参数。这部分配置信息属于侧行信道状态信息配置信息中的测量配置部分，其中测量侧行信道状态信息参考信号的时域粒度是指CSI是根据多少个时域符号上的CSI-RS测量得到的，测量侧行信道状态信息参考信号的频域粒度是指基于RB还是基于子信道测量CSI，信道状态信息中包括的参数是指需要上报的CSI参数，这些CSI参数可包括信道质量指示(channel quality indicator，CQI)、阶数指示(rank indicator，RI)、预编码矩阵指示(precoding matrix indicator，PMI)、参考信号接收功率(reference signal receiving power，RSRP)中的一项或多项。如此，第一终端设备在接收到该侧行信道状态信息配置信息后，可根据该侧行信道状态信息配置信息中的测量配置，对侧行信道状态信息参考信号进行测量，得到信道状态信息。
侧行信道状态信息配置信息中还可包括信道状态信息的发送资源、发送次数和发送时间间隔中的一项或多项。这部分配置信息属于侧行信道状态信息配置信息中的上报配置部分，其中，信道状态信息的发送资源是指第一终端设备发送该信道状态信息可以使用的时域资源或时频资源；信道状态信息的发送次数是指第一终端设备接收到该侧行信道状态信息配置信息后，重复发送信道状态信息的次数，也可以理解为信道状态信息的发送数量； 信道状态信息的发送时间间隔是指第一终端设备重复发送多次信道状态信息时，相邻两次信道状态信息之间的发送时间间隔。如此，第一终端设备在接收到该侧行信道状态信息配置信息后，可根据第二终端设备在侧行信道状态信息配置信息中指示的上报方式，发送信道状态信息。
需要说明的是，侧行信道状态信息配置信息中还可包括源节点标识和目的节点标识，这里，源节点标识是指第二终端设备的标识，目的节点标识是指第一终端设备的标识，表示该侧行信道状态信息配置信息是由第二终端设备发送给第一终端设备的。应理解，该侧行信道状态信息配置中还可以包括其他信息，例如，侧行信道状态信息参考信号的模式(pattern)、信道状态信息的上报条件等，本申请对此并不限定。
在步骤S203中，第一终端设备可向第二终端设备发送第一控制信息和信道状态信息，当第一终端设备完成了侧行信道状态信息配置信息中指示的发送次数、发送时间间隔后，一次信道状态信息上报的程结束。在此之后，若第一终端设备再次接收到第二终端设备发送的侧行信道状态信息配置信息，则会触发下一次的信道状态信息上报的流程。
