Description

通信方法，装置和可读存储介质
本申请要求于2022年5月26日提交中国国家知识产权局、申请号为202210582445.X、申请名称为“通信方法，装置和可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，更具体地，涉及一种通信方法，装置和可读存储介质。
背景技术
目前，终端设备与终端设备之间传输的数据可以称为侧行链路(sidelink，SL)数据。为了能够实现SL数据的可靠传输，终端设备可以在多个载波中选择信道繁忙程度较低的载波进行SL数据的传输。例如，网络设备可以为每个载波配置至少一个资源池，不同的资源池可以对应不同的区域标识，终端设备根据所处位置的区域标识确定唯一对应的资源池，并根据该资源池的配置参数进行信道繁忙率(channel busy ratio，CBR)测量，进而选择CBR较低的载波传输SL数据，其中终端设备所确定的唯一的资源池为该终端设备用于所述SL数据传输的候选资源池。
随着通信技术的发展，为了实现更为灵活的SL数据传输，终端设备可以使用载波中的一个或多个资源池传输SL数据。例如，终端设备可以根据SL数据的数据量大小选择载波中合适的一个或多个资源池进行SL数据传输。但是在这种场景中，目前并没有定义终端设备如何通过确定载波的繁忙程度从多个载波中选择用于所述SL数据传输的载波。
发明内容
本申请提供一种通信方法，装置和可读存储介质，以期终端设备在支持使用载波中的一个或多个资源池传输侧行链路SL数据，也即，载波中用于该终端设备侧行链路SL数据传输的候选资源池的数量可以为多个时，能够通过确定载波的繁忙程度选择用于所述SL数据传输的载波。
第一方面，提供了一种通信方法，该方法可以由终端设备或者终端设备中的芯片实现，该方法包括：第一终端设备获取第一载波中的多个资源池中的部分或者全部资源池中每个资源池的测量结果，该部分或者全部资源池中每个资源池的测量结果用于确定第一载波的信道繁忙率，第一载波的信道繁忙率用于从多个载波中确定该第一载波；第一终端设备使用该第一载波与第二终端设备进行侧行链路数据的传输；其中，第一载波中的多个资源池为用于侧行链路数据的传输的候选资源池。
第一载波中的多个资源池可以是网络设备为第一终端设备配置的资源池，每个资源池可以基于自身的配置参数进行测量以获得测量结果，其中，该配置参数可以包括以下参数中的一项或多项：用于指示一个子信道中的物理资源块数量的参数、用于指示进行测量的测量时间的参数、用于指示用于确定繁忙子信道的预设阈值的参数(例如，当第一终端设 备测量接收信号强度指示RSSI时，该预设阈值可以为与RSSI进行比较的阈值)。
该第一载波可以是多个载波中信道繁忙率最低的前L个载波，其中L为正整数且小于该多个载波的数量，从而实现SL数据的可靠传输。其中，L的取值可以基于协议预定义，或，网络设备的配置，或，所述SL数据的传输需求，确定。
第一终端设备与第二终端设备进行侧行链路数据的传输可以包括：第一终端设备向第二终端设备发送侧行链路数据，和/或第一终端设备接收来自第二终端设备的侧行链路数据。
基于该技术方案，第一终端设备可以获取载波中的部分或者全部资源池的测量结果，并且基于该部分或者全部资源池的测量结果获取该载波的信道繁忙率，进而使得终端设备能够在多个载波中确定用于进行SL数据的传输的一个或多个载波。
另外，第一终端设备可以参考或者使用资源池的配置参数获取该部分或者全部资源池中每个资源池的测量结果，从而减少终端设备和网络设备之间的信令传输，减少信令开销。
需要说明的是，在本申请实施例中，参考某一信息(例如测量结果、参数等)可以是指对该信息进行适当的处理，例如可以对该参数进行运算，再例如可以从多个可供参考的参数中选取一个参数；使用某一信息既可以是指对该信息不作处理进行使用，例如，可以直接使用某一参数，也可以包括前述“参考”的含义。
结合第一方面，在第一方面的某些实现方式中，部分或全部资源池是根据多个资源池中每个资源池的以下信息中的至少一项确定的：子信道的数量、资源块的数量、子信道包括的资源块的数量。

基于该技术方案，一个资源池中的子信道或资源块的数量可以影响该资源池在确定载波的信道繁忙率过程中的重要程度，进而，终端设备或者网络设备可以综合多个参数选择合适的资源池用于载波的信道繁忙率的确定，从而提高该信道繁忙率的可信度。

或者，该部分或者全部资源池为多个资源池中测量结果大于或等于第一特定阈值的资源池，再或者，该部分或者全部资源池为多个资源池中测量结果小于或等于第二特定阈值的资源池，再或者，该部分或者全部资源池为多个资源池中测量结果处于特定区间的资源池。其中，第一特定阈值，第二特定阈值或特定区间的取值可以基于协议预定义，或，网络设备的配置，或，所述SL数据的传输需求，确定。
基于该技术方案，可以根据不同的场景需求，确定采用测量结果较高或者较低的一个或多个资源池的测量结果确定第一载波的信道繁忙率，例如在进行侧行链路通信的用户较多的场景中，较高的测量结果较为可靠，从而可以选择测量结果较高的资源池的测量结果确定第一载波的信道繁忙率；再例如在进行侧行链路通信的用户较少的场景中，可以选择测量结果较低的资源池的测量结果确定第一载波的信道繁忙率，从而能够增加载波的利用率，进而本技术方案能够支持多种场景的运用。可以理解的是，本申请中的“较高”可以是指比一相应阈值高，“较低”可以是指比一相应阈值低。

本申请实施例适用的通信系统主要包括终端设备，例如图1所示的终端设备121与终端设备122，以及网络设备，例如图1所示的网络设备110。另外，该通信系统主要包括两种通信接口，例如分别为终端设备121与网络设备110之间的通信接口(Uu口)，和终端设备121与终端设备122之间的通信接口(PC5口)，其中Uu口用于终端设备与网络设备之间的通信，PC5口用于终端设备与终端设备之间的侧行链路通信。Uu口上终端设备发送数据给网络设备的链路称为上行链路(uplink)，而终端设备接收网络设备发送的数据的链路称为下行链路(downlink)。PC5口上的终端设备和终端设备之间传输数据的链路称为侧行链路(sidelink)或直通链路。侧行链路一般用于设备到设备(device to device，D2D)等可以在设备间进行直联通信的场景，在该场景中，设备之间的数据传输不需要经过网络设备。车联网(vehicle to everything,V2X)通信可以看成是D2D通信的一种情形。
在Uu口上，终端设备和网络设备之间通过无线承载来传输数据和无线资源控制(radio resource control，RRC)信令中的一项或多项。其中，用于传输数据的无线承载称为数据无线承载(data radio bearer，DRB)，用于传输RRC信令的承载称为信令无线承载(signaling radio bearer，SRB)。一个无线承载包括分组数据汇聚协议(packet data convergence protocol，PDCP)实体和无线链路控制(radio link control，RLC)承载。其中，一个RLC承载包括一个RLC实体和对应的逻辑信道(Logical Channel,LCH)。无线承载的配置即为该无线承载的PDCP实体，RLC实体和逻辑信道的配置。无线承载的配置需要能够保证通过该无线承载传输的业务的服务质量(quality of service，QoS)要求。在Uu口，无线承载的配置由网络设备为终端设备配置。
在PC5口上，终端设备和终端设备之间也通过无线承载来传输数据和RRC信令中的一项或多项。PC5口上的无线承载可以称为侧行链路无线承载(sidelink radio bearer，SL RB)。在长期演进(long term evolution，LTE)V2X系统中，PC5口上的无线承载分别由发送端终端设备和接收端终端设备自己建立，无线承载的配置通过标准预定义或者由发送端终端设备和接收端终端设备自己确定。
在未来通信中，Uu口或PC5口这些接口的名称可以不变，或者也可以用其它名称代替，本申请对此不作限定。

本申请中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。
本申请实施例中的网络设备，也可以称为接入网(radio access network,RAN)设备。
RAN设备为将终端设备接入到无线网络的节点或设备，RAN设备又可以称为基站。RAN设备例如包括但不限于：基站、5G中的下一代节点B(generation nodeB，gNB)、演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(base band unit，BBU)、收发点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、和/或移动交换中心等。或者，接入网设备还可以是集中单元(centralized unit，CU)、分布单元(distributed unit,DU)、集中单元控制面(CU control plane，CU-CP)节点、集中单元用户面(CU user plane，CU-UP)节点、接入回传一体化(integrated access and backhaul，IAB)、或云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器等中的至少一个。或者，接入网设备可以为中继站、接入点、车载设备、终端设备、可穿戴设备、5G网络中的接入网设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的接入网设备等。

上述图1所示的本申请实施例能够应用的架构仅是一种举例说明，适用本申请实施例的架构并不局限于此，任何能够实现上述各个设备的功能的架构都适用于本申请实施例。
还应理解，上述命名仅为便于区分不同的功能而定义，不应对本申请构成任何限定。本申请并不排除在5G网络以及未来其它的网络中采用其他命名的可能。例如，在6G网络中，上述各个设备中的部分或全部可以沿用5G中的术语，也可能采用其他名称等。图1中的各个设备之间的接口名称只是一个示例，具体实现中接口的名称可能为其他的名称，本申请对此不作具体限定。此外，上述各个设备之间的所传输的消息(或信令)的名称也仅仅是一个示例，对消息本身的功能不构成任何限定。
为了便于理解本申请实施例，首先对本申请中涉及到的术语做以下说明。
1、载波
电磁频谱通常基于频率/波长而被细分为各种类别、频带、信道等。在5G NR中，定义了两种频段范围，FR1和FR2，FR1(410MHz-7.125GHz)表示低频频段。FR2(24.25GHz-52.6GHz)表示毫米波高频频段，是5G的扩展频段。在FR1和FR2之间的频率通常称为中频频段。
这些频段范围被分成多个载波，网络设备与终端设备之间或终端设备与终端设备之间可以利用所分配的载波进行通信。
2、侧行链路中资源池(resource pool)
终端设备可以使用侧行链路资源池中的资源进行数据传输，一个资源池可以在频域上配置一个或多个连续的物理资源块(physical resource block，PRB)，在时域上配置一个或多个时隙(slot)，其中多个时隙可以是连续或者非连续的。为了便于理解资源池的含义，以下结合图2对侧行链路中的资源池进行示例性说明。
图2示出了一种多个资源池的示意图。载波带宽(carrier bandwidth)中的一部分用于SL的频谱可以称为侧行部分带宽SL BWP(sidelink bandwidth part)，SL BWP内可以定义多个资源池，例如图2示出的三个资源池。以其中一个资源池进行是示例性说明，一个资源池在频域上可以配置有多个连续的PRB，一定数量的连续的PRB可以组成一个子信道，终端设备可以使用一个或多个子信道传输SL数据。换句话说，终端设备发送或者接收SL数据的最小单位粒度可以称为子信道，一个子信道中PRB的数量可以是10、12、15、20、25、50、75或100个。一个资源池在时域上可以配置多个能够用于该终端设备的SL传输的时隙。示例性地，终端设备可以通过物理层的同步信号(例如同步信号块(synchronization signal block，SSB))确定该多个时隙所属时域范围的起始时隙，其中，该多个时隙所属时域范围可以为可以用于多个终端设备SL数据传输的多个连续的时隙，比如10个时隙(slot)，20个时隙，40个时隙，或，100个时隙等。可以通过位图(bitmap)的方式指示该多个能够用于该终端设备的SL传输的时隙在所属时域范围内的位置。例如，位图“0011000000”可以表示在10slot的时域范围内第3、4个时隙为能够用于该终端设备的SL传输的时隙，即该终端设备的资源池在时域上配置的为该第3、4个时隙。可以理解的是，位图中每个比特(bit)所代表的时间单元数，比如时隙数，可以为一个或多个，具体数量可以基于协议预定义，或，由网络设备配置。
终端设备可以被配置多个用于多个终端设备的SL传输的资源池，在一种可能的实现 方式中，终端设备用于该终端设备SL传输的候选资源池只有唯一的一个。例如，在LTE V2X中，终端设备根据所在位置的区域标识(zone ID)从网络设备指示的用于多个终端设备的多个资源池中确定唯一的一个候选资源池进行SL传输。
在另一种可能的实现方式中，终端设备进行SL传输的候选资源池的数量可以多于一个。例如，在NR V2X中，当终端设备的配置参数设置为sl-ScheduedCofig时，终端设备可以采用模式1(mode 1)的方式进行SL传输，也就是说终端设备在传输SL数据或者信令时，可以将SL数据或者信令填充至一个或者多个资源池中。当终端设备的配置参数设置为sl-SelectedConfig时，终端设备可以采用模式2(mode 2)的方式进行SL传输，也就是说终端设备可以在多个资源池中选择一个或多个资源池进行数据传输，即在模式2下用于侧行链路数据传输的候选资源池也可以有多个。
3、信道繁忙率(channel busy ratio，CBR)
CBR可以用于表示信道的繁忙程度，例如，若CBR的值较高，则可以表示附近有较多的用户占用该信道，或者，存在与作为CBR测量方的终端设备较近的终端设备占用该信道。其中，“占用”不限于SL数据的传输，可以包括Uu口数据的传输，或，其他无线数据的传输，在此不予限定。可选的，该CBR可以用于终端设备或者网络设备选择传输SL数据的资源，为了保证SL数据传输的可靠性，终端设备或者网络设备可以选择CBR较低的载波进行SL数据传输。
在目前的通信系统中，终端设备可以通过测量子信道的接收信号强度指示(received signal strength indications，RSSI)确定CBR取值，其中RSSI可以表示接收信号的强度，RSSI持续过高可以表示接收的信号受到的干扰较大。例如，一个资源池的CBR可以定义为在测量CBR的时间窗长度内，繁忙的子信道占该资源池全部子信道的比率，其中，时间窗长度与资源配置参数相关，例如，资源配置参数以时隙为粒度时，该时间窗长度可以设置为100个时隙，或者资源配置参数以毫秒为粒度，该时间窗长度可以设置为100毫秒。该时间窗应在前述配置用于该终端设备的SL传输的时隙之前，比如，基于前述配置用于该终端设备的SL传输的时隙和所述终端设备基于所述CBR确定用于该终端设备的SL传输的载波后为SL传输做准备的时间确定该时间窗。当子信道的RSSI值大于预定阈值时，该子信道可以认为是繁忙的子信道。可以理解的是，本申请中的“预定”可以为协议预定义，预存储，预配置，预设置，或，预烧制，在此不予限定。
在一种实施方式中，终端设备可以使用资源池的配置参数进行CBR测量。例如，sl-SubchannelSize-r16可以指示一个子信道中的PRB数，sl-ThreshS-RSSI-CBR-r16可以指示RSSI的预定阈值，sl-TimeWindowSizeCBR-r16可以指示测量CBR的时间窗长度。进而在终端设备使用一个资源池的情况下，终端设备可以使用资源池的配置参数进行CBR测量。
可见，上文所示的测量CBR，以及根据CBR选择载波的方式可以适用于在测量CBR时用于SL传输的候选资源池只有确定的一个的场景，例如，在测量CBR时就已经根据自身的zone ID获知用于SL传输的唯一的资源池。如果终端设备在测量CBR的过程中，并不知道实际进行SL传输的资源池时，也即候选资源池不确定时，上文所示的方式便不能够被实现。本申请提出了一种通信方法和装置，使得终端设备在支持使用载波中的一个或多个资源池传输SL数据，即，用于该终端设备的SL数据传输的候选资源池的数量为多个时，能够确定载波的繁忙程度。以下对该通信方法进行说明。
图3是本申请实施例提出的一种通信方法的示意性流程图。
S310，第一终端设备获取第一载波中的多个资源池中的部分或者全部资源池中每个资源池的测量结果。
该部分或者全部资源池中每个资源池的测量结果用于确定第一载波的信道繁忙率，第一载波的信道繁忙率用于从多个载波中确定该第一载波。
该第一载波可以是被配置为使用其中的一个或者多个资源池进行SL传输的载波，例如，第一载波可以是第一终端设备的配置参数设置为sl-ScheduedCofig时对应的载波。
第一载波中的多个资源池可以是网络设备为第一终端设备配置的资源池，例如，网络设备可以通过侧行链路信息单元(sidelink information elements)中的参数SL-BWP-PoolConfig为第一终端设备配置8个资源池。
多个资源池中的部分或者全部资源池可以是指：该部分或者全部资源池可以是该多个资源池中的一个资源池，或者是该多个资源池中的部分多个资源池，或者是该多个资源池的全部资源池。
以下对该部分或者全部资源池中的一个资源池(例如第一资源池)的测量结果进行示例性说明。
第一资源池的测量结果为第一繁忙子信道的数量占第一资源池的子信道总数的比值。其中，第一繁忙子信道为第一资源池的子信道中接收测量值大于或等于第一阈值的子信道，接收测量值可以为以下值中的至少一项：接收信号强度指示RSSI、参考信号接收功率或者参考信号接收质量。
第一终端设备在对第一资源池进行CBR测量的测量过程中，可以使用或者参考第一资源池中的相关参数(例如参见上文侧行链路中的CBR介绍的相关参数)进行测量。进而，第一终端设备可以获取该部分或者全部资源池中每个资源池的测量结果。
以上介绍了资源池的测量结果的获取方式，以下对如何确定该部分或者全部资源池进行说明。
在一种可能的实现方式中，第一终端设备可以根据网络设备的指示确定部分或者全部资源池。在这种方式中，步骤S310可以由步骤S311和步骤S312实现。
S311，网络设备向第一终端设备发送第一信息，对应地，第一终端设备接收来自网络设备的第一信息。
该第一信息用于指示该部分或者全部资源池，其中，指示方式可以为直接指示或间接指示。可以理解的是，本申请中间接指示，比如A间接指示C可以通过A指示B，以及B和C的对应关系来实现。B和C的对应关系可以为协议预定义的或预配置的，在此不予限定。
可选地，该第一信息还用于指示第一终端设备对第一信息指示的部分或者全部资源池进行CBR测量。
在一种可能的实现方式中，该第一信息可以指示该部分或者全部资源池的标识信息，例如该第一信息可以包括该部分或者全部资源池的标识，或者第一信息包括该部分或者全部资源池的在资源中的位置信息(例如该部分或者全部资源池对应的时隙号或子信道号等)。
示例性地，网络设备可以在向第一终端设备发送第一信息之前，根据多个资源池中每 个资源池的以下信息中的至少一项确定该部分或者全部资源池：子信道的数量、资源块的数量、子信道包括的资源块的数量。例如，网络设备可以选取子信道数量、资源块的数量或者子信道包括的资源块的数量最多的资源池；或者选取子信道数量、资源块的数量或者子信道包括的资源块的数量大于特定阈值的资源池；或者网络设备对子信道的数量、资源块的数量、子信道包括的资源块的数量中的一项或多项进行运算，选取运算结果达到预设条件的资源池。部分或者全部资源池的确定方式可以根据实际的运用场景进行设计，本申请对此不作特别限定。进而，网络设备可以通过第一信息将确定的部分或者全部资源池的标识信息发送给第一终端设备，第一终端设备可以基于第一信息获取该部分或者全部资源池的测量结果，而无需获取除该部分或全部资源池之外的资源池的测量结果，可以节省测量资源。
在另一种可能的实现方式中，该第一信息可以指示确定该部分或者全部资源池的方式。示例性地，网络设备可以通过第一信息告知第一终端设备如下方式中的一项或多项：
方式1：
第一终端设备可以根据多个资源池中每个资源池的以下信息中的至少一项确定该部分或者全部资源池：子信道的数量、资源块的数量、子信道包括的资源块的数量。
该方式与上文描述的网络装备确定部分或者全部资源池的描述类似，在此不予赘述。
方式2：
第一终端设备可以根据多个资源池中每个资源池的测量结果确定该部分或者全部资源池。
示例性地，该部分或者全部资源池为多个资源池按测量结果递增排序的前N个资源池。或者，该部分或者全部资源池为所述多个资源池按测量结果递减排序的前M个资源池，其中，所述N和所述M为正整数。或者，该部分或者全部资源池为多个资源池中测量结果大于或等于特定阈值的资源池。再或者，该部分或者全部资源池为多个资源池中测量结果小于或等于特定阈值的资源池。再或者，该部分或者全部资源池为多个资源池中测量结果处于特定区间的资源池。进而，第一终端设备可以获取第一载波中的每个资源池的测量结果，并根据每个测量结果确定部分或者全部资源池。
可以理解的是，网络设备可以直接指示该部分或者全部资源池的方式。或者，网络设备可以间接指示确定方式，例如，网络设备和第一终端设备预先约定确定方式的编号标识，进而该第一信息可以包括方式的编号间接指示确定方式。或者，网络设备也可以采用直接指示和间接指示相结合的方式指示确定方式，例如，该第一信息包括上述N的数值，间接指示第一终端设备选取测量结果递增排序的前N个资源池。可选的，网络设备和终端设备可以基于协议预定义采用前述多种方式中的一种，比如，该部分或者全部资源池为多个资源池按测量结果递增排序的前N个资源池，确定该部分或者全部资源池，这种情况下，该第一信息可以指示该方式对应的参数，例如，该第一信息可以包括上述方式中N的数值，换句话说，该第一信息所指示的N的数值，网络设备和第一终端设备基于预先的规则解析为该部分或者全部资源池为多个资源池按测量结果递增排序的前N个资源池。本申请对此不作特别限定。
以上对第一信息指示全部或者部分资源池的两种方式进行了说明。
需要说明的是，第一信息还可以用于指示第一终端设备返回部分或者全部资源池的测 量结果，或者，协议预定义第一终端设备返回部分或者全部资源池的测量结果，这样，网络设备可以根据该测量结果确定第一载波的信道繁忙率。或者，该第一信息还可以用于指示第一终端设备根据该部分或者全部资源池的测量结果确定第一载波的信道繁忙率，或者，协议预定义第一终端设备根据该部分或者全部资源池的测量结果确定第一载波的信道繁忙率，这样第一终端设备可以根据测量结果确定第一载波的信道繁忙率。
可选的，第一载波的信道繁忙率的确定方式可以包括以下中的一种或多种。当确定方式有多种时，具体的确定方式也可以通过前述第一信息来直接或间接指示。或者，确定方式也可以为协议预定义的其中一种，在此不予限定。
示例性地，部分或全部资源池的数量为一个或多个，比如第一载波中的多个资源池中子信道的数量最大的前K个资源池为用于确定第一载波的信道繁忙率的一个或多个资源池，K为正整数且小于该多个资源池的数量。在K等于1，即用于确定第一载波的信道繁忙率的资源池的数量为一个的情况下，第一载波的信道繁忙率可以是该确定的一个资源池的测量结果。在K大于或等于2，即用于确定第一载波的信道繁忙率的部分或全部资源池的数量为多个的情况下，那么第一载波的信道繁忙率可以是对多个测量结果进行处理后获得的。例如，第一载波的信道繁忙率可以为部分或者全部资源池的测量结果的平均值。或者，再例如，第一载波的信道繁忙率可以为部分或者全部资源池的测量结果的加权平均值，比如可以满足式1：
CBRcarrier＝ω1*CBRRP1+ωi*CBRRPi+……+ωs*CBRRPs          式1
其中，CBRcarrier表示第一载波的信道繁忙率，CBRRPi表示s个部分或者全部资源池中第i个资源池的测量结果，ωi表示第i个资源池的测量结果对应的加权系数，s为正整数。
加权系数ωi可以与第i个资源池的子信道总数正相关，例如，该加权系数ωi可以为第i个资源池的子信道总数占该部分或者全部资源池的子信道总数的比值。
或者，加权系数ωi可以与第i个资源池的资源块总数正相关，例如，该加权系数ωi可以为第i个资源池的资源块总数占该部分或者全部资源池的资源块总数的比值。
可以理解的是，在本申请中，正相关的含义是指自变量增长(例如子信道总数)，因变量(加权系数)也跟着增长，两个变量的变动方向相同，而正比例关系是正相关的其中一种形式，本申请对正相关的形式不作任何限定。
S312，第一终端设备获取该部分或者全部资源池中每个资源池的测量结果。
第一终端设备可以基于第一信息在第一载波的多个资源池中选取该部分或者全部资源池，对该部分或者全部资源池进行测量，以获得部分或者全部资源池中每个资源池的测量结果。第一终端设备选取部分或者全部资源池的方式可以参见步骤S311的相关描述，第一终端设备对该部分或者全部资源池进行测量的方式可以参见步骤S310的相关描述，在此不予赘述。
以上对网络设备指示第一终端设备部分或者全部资源池的方式进行了说明。
在另一种可能的实现方式中，第一终端设备可以根据预设置的确定方式从多个资源池中确定该部分或者全部资源池。步骤S310可以由步骤S312实现。也就是说，第一终端设备可以通过预配置的方式获知确定部分或者全部资源池的方式，也即，第一终端设备基于协议预定义自行确定相应的确定部分或者全部资源池的方式。比如，第一终端设备可以基于多个资源池中每个资源池的子信道的数量、资源块的数量或者子信道包括的资源块的数 量中的一项或多项确定该部分或者全部资源池，或者第一终端设备也可以根据多个资源池中每个资源池的测量结果确定该部分或者全部资源池。确定的方式可以与步骤S311中描述的类似，在此不予赘述。

其中，第一终端设备或者网络设备基于S320确定的第一载波的信道繁忙率，确定第一载波用于SL数据的传输。其中，第一载波为多个载波中的一个。
从多个载波中确定第一载波的方式，可以包括如下中的一种，具体为哪种方式可以由协议预定义，在网络设备和第一终端设备预设置，或者，由网络设备进行配置：
确定多个载波中的一个或多个载波的信道繁忙率，将前述一个或多个载波的信道繁忙率大于预定阈值的一个或多个第一载波确定为用于SL数据传输的载波；或，
对多个载波确定各自的信道繁忙率，并依据该多个载波对应的信道繁忙率的排序，确定信道繁忙率最低的一个或多个第一载波为用于SL数据传输的载波。

S322c，第一终端设备向网络设备发送第一载波的信道繁忙率，对应地，网络设备接收来自第一终端设备的该第一载波的信道繁忙率。
可以理解的是，和“指示”包括直接指示和间接指示类似，本申请中的信息发送并不 限定信息发送的方式，比如，可以是发送该信息，比如发送所述第一载波的信道繁忙率本身，或者，也可以是发送该信息对应的信息，比如发送用于指示第一载波的信道繁忙率的信息，比如和所述第一载波的信道繁忙率对应的索引。
可选地，第一终端设备可以确定包括第一载波的多个载波的信道繁忙率，并将该多个载波的信道繁忙率发送给网络设备，从而网络设备可以基于该多个载波的信道繁忙率在该多个载波中确定用于传输SL数据的第一载波。
从而，上文介绍的步骤S320和S330的可能的实现方式可以灵活使用，进而支持丰富的运用场景。
S340，第一终端设备使用第一载波与第二终端设备进行侧行链路数据的传输。
可以理解的是，本申请中的传输可以包括第一终端设备向第二终端设备发送侧行链路数据，或，第二终端设备向第一终端设备发送侧行链路数据。
基于该技术方案，第一终端设备可以获取载波中的部分或者全部资源池的测量结果，并且基于该部分或者全部资源池的测量结果获取该载波的信道繁忙率，进而使得终端设备能够在多个载波中选择用于进行SL数据的传输的载波。
在图3和图4所提供的通信方法中，终端设备可以基于资源池的测量结果确定第一载波的信道繁忙率，该方法可以利用资源池的相关参数，比如上文侧行链路中的CBR介绍的相关参数，对资源池进行测量，能够减少终端设备和网络设备之间空口消耗。本申请还提供了一种通信方法，可以基于载波的信道繁忙率的定义进行载波的CBR测量，即采用载波粒度的参数确定第一载波的信道繁忙率，使得终端设备能够在多个载波中选择用于进行SL数据的传输的载波进行SL数据的传输。以下结合图5对该方法进行说明。
图5示出了另一种载波CBR的确定方法的示意性流程图。
S510，第一终端设备确定第一载波的信道繁忙率。
第一载波的信道繁忙率为繁忙子信道的数量占全部子信道的数量的比值。
繁忙子信道为全部子信道中接收测量值大于或等于测量阈值的子信道，其中，接收测量值为以下值中的至少一项：接收信号强度指示、参考信号接收功率或者参考信号接收质量。有关繁忙子信道的定义可以参考图3中步骤S310中的描述，在此不予赘述。可以理解的是，该测量阈值为用于确定载波信道繁忙率的繁忙子信道的测量阈值，其可以不同于用于确定资源池信道繁忙率的繁忙子信道的测量阈值。
全部子信道的定义可以采用如下两种方式，以下结合图6分别对该两种方式进行说明。
方式1：
全部子信道为第一载波中配置用于侧行链路SL数据传输的候选资源池所包括的子信道。
第一载波中的候选资源池所包括的子信道是经过去重处理后包括的子信道。例如，对于配置频分复用方式的候选资源池，如果候选资源池在频域上存在子信道重叠的情况，参见图6(a)，第一载波中包括三个候选资源池#1-3，候选资源池#1包括的子信道为子信道#1-3，候选资源池#2包括的子信道为子信道#3-5，候选资源池#3包括的子信道为子信道#7-9。那么全部子信道为子信道#1-5以及子信道#7-9。即使候选资源池#1和候选资源池#2在子信道#3上存在重叠，那么第一载波中的候选资源池所包括的子信道不会重复包括子信道#3。
第一终端设备可以在经过去重处理后的全部子信道，例如图6(a)所示的子信道#1-5以及子信道#7-9上进行测量，获取每个子信道的接收测量值，基于测量阈值确定第一载波的信道繁忙率。
需要说明的是，对于配置时分复用方式的候选资源池，参见图6(b)，如果候选资源池在时域上存在时隙(或者其它时间单元粒度)重叠的情况下，候选资源池#1包括时隙#1-3，候选资源池#2包括时隙#3-5，候选资源池#3包括时隙8-10，如果第一终端设备的测量接收测量值的时间包括重复的时隙#3，那么第一终端设备在测量候选资源池所包括的子信道时，对时隙#3也进行去重处理。
方式2：
全部子信道为第一载波中配置用于确定第一载波的信道繁忙率的子信道。
其中，全部子信道的数量，也可以替换为子信道总数。
网络设备可以为第一终端设备配置用于确定第一载波的信道繁忙率的子信道。可以理解的是，在该实现方式中，该全部子信道是指用于确定信道繁忙率的全部的子信道，全部子信道可以是配置用于传输侧行链路SL数据的所有子信道，这样可以使得第一载波的CBR更准确，或者，也可以是配置用于传输SL数据的所有子信道中的部分子信道，这样可以减少终端设备的测量量，比如，该部分子信道是用于传输侧行链路SL数据的所有子信道中每R个中的一个且均匀分布，或者，和，配置用于传输SL数据的所有子信道部分重叠，即可以包括第一载波中不是配置用于传输SL数据的子信道，这样，可以引入非SL传输，比如Uu口的测量，可以使第一载波的CBR的确定更准确。
可选的，配置用于确定第一载波的信道繁忙率的子信道的粒度，即每个子信道包括的PRB的数量，可以和配置用于侧行链路SL数据传输的子信道的粒度相同，这样，可以减少配置的信令，提高终端设备处理的一致性。
可选的，配置用于确定第一载波的信道繁忙率的子信道的粒度，即每个子信道包括的PRB的数量，可以和配置用于侧行链路SL数据传输的子信道的粒度不同，这样，可以采用更适用于用于确定第一载波的信道繁忙率的子信道的配置，使得该配置更符合系统需求。
示例性地，图7示出了一种配置的用于确定第一载波的信道繁忙率的子信道的示意图。参加图7，子信道#1至子信道#4是配置用于确定第一载波的信道繁忙率的子信道，每个子信道可以包括至少一个PRB，每个子信道包括的PRB的个数可以相同也可以不同，用于确定第一载波的信道繁忙率的子信道可以是连续的也可以是非连续的。
其中，在上述两种方式中，测量参数可以包括以下中的一项或多项：配置用于确定第一载波的信道繁忙率的子信道(即全部子信道)的数量、全部子信道的频域位置、全部子信道中每个子信道中包括的PRB的个数、测量阈值、测量接收测量值的时间。以上测量参数可以是预先配置(例如协议预定义)的，或者也可以是网络设备指示的，或者测量参数中的一部分是预先配置的，一部分是网络设备指示的，该指示可以为直接指示或间接指示。比如，第一终端设备中配置有多组测量参数，以及与每组测量参数具有对应关系的索引，(例如以表格或字符串的形式存储前述对应关系)，第一终端设备可以基于网络设备指示的索引确定配置用于所述第一载波的CBR的参数。
例如，在上述的方式1中，全部子信道为第一载波中配置用于SL数据传输的候选资源池所包括的子信道，全部子信道的数量、全部子信道的频域位置、全部子信道中每个子 信道中包括的PRB的个数、测量接收测量值的时间可以采用参考或者使用所在的候选资源池中的参数(例如上文侧行链路中的CBR介绍的相关参数)确定，比如，直接采用所述候选资源池中的参数，或者，是所述候选资源池中的参数的函数，具体函数可以为预定义的；测量阈值可以为协议预定义的，即预先配置的，或者，通过网络设备指示的方式确定。
再例如，在上述的方式2中，全部子信道为第一载波中配置用于确定第一载波的信道繁忙率的子信道，上述测量参数中的全部或部分可以预存储或预配置在所述第一终端设备中，或者也可以基于网络设备的指示确定。
当测量参数中存在一个或多个测量参数由网络设备指示给第一终端设备时，在步骤S510之前，该方法还可以执行步骤S520。
可选地，S520，网络设备向第一终端设备发送参数信息，该参数信息指示进行测量时的前述测量参数中的一项或多项，对应地，第一终端设备接收来自网络设备的该参数信息。
示例性地，在方式1中，进行测量时的参数可以包括该测量阈值。该测量阈值可以由协议预定义也可以由网络设备配置给第一终端设备。
需要说明的是，第一终端设备在对资源池所包括的子信道进行测量时，可以参考各个资源池的配置参数确定测量接收测量值的时间(例如参考sl-TimeWindowSizeCBR-r16指示的测量CBR的时间窗长度)、子信道中的PRB数(例如参考sl-SubchannelSize-r16指示的PRB数)进行测量，以获取每个子信道的接收测量值，然后可以与前述测量阈值进行比较。
再示例性地，在方式2中，进行测量时的参数可以包括以下信息中的至少一项：测量阈值、测量接收测量值的时间、该全部子信道的频域位置、该全部子信道中每个子信道包括的资源块的数量。这些参数中的全部或部分可以由协议预定义，或者，由网络设备配置给第一终端设备，比如，通过参数信息指示前述参数中的一项或多项，具体配置方式可以是直接配置，也可以是间接配置。也就是说，网络设备可以以载波粒度配置用于确定载波的信道繁忙率的参数。
例如，该参数信息可以以时隙的粒度指示测量接收测量值的时间，或者也可以以其它时间单元(例如毫秒)的粒度指示测量接收测量值的时间。另外，该参数信息可以通过指示全部子信道中的起始子信道的起始PRB位置和子信道包括的PRB数指示每个子信道频域位置。即第一终端设备可以结合预先配置的参数，例如子信道之间间隔PRB的个数，以及参数信息指示的起始PRB位置和子信道包括的PRB数确定全部子信道中每个子信道的频域位置。可以理解的是，该参数信息可以采用多种形式指示用于测量全部子信道的参数，本申请对次不作特别限定。
S530，第一终端设备基于第一载波的信道繁忙率从多个载波中确定第一载波。
示例性地，第一终端设备可以选取多个载波中信道繁忙率较小的载波作为用于SL传输的第一载波。也即，第一终端设备可以针对多个载波进行和前述第一载波的信道繁忙率类似的载波信道繁忙率的确定，并将信道繁忙率较小的载波，比如本申请中的第一载波，用于SL数据的传输(也简称为SL传输)。可以理解的是，本申请的SL数据，包括SL业务数据，也包括信令。
S540，第一终端设备使用第一载波与第二终端设备进行侧行链路数据的传输。
基于该技术方案，第一终端设备可以基于用于确定第一载波的信道繁忙率的参数对全部子信道进行测量，进而使得终端设备能够在多个载波中选择用于进行SL数据的传输的载波进行SL数据的传输。
