具体实施方式
为了更好的理解本公开实施例公开的一种CBR的确定方法和装置，下面首先对本公开实施例适用的通信系统进行描述。
图1示出了本公开实施例可应用的通信系统100。通信系统100可以是长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)通信系统、新空口(newradio，NR)通信系统，还可以是机器与机器(machine to machine，M2M)通信系统、车联网通信系统、设备对设备(device to device，D2D)通信系统、第六代及后续未来演进的通信系统等。
如图1所示，通信系统100可以包括：至少一个终端设备101。其中，终端设备101与终端设备101之间可通过无线接口(如PC5接口)进行通信。在PC5接口上，终端设备101与终端设备101之间传输数据的链路可以称为侧链路(sidelink，SL)。本公开实施例中的侧链路还可以称为侧行链路或直通链路。
SL通信一般用于车到一切(vehicle to everything，V2X)或D2D等设备直联通信的场景。V2X是指把车联到网或车联成网，包括4种不同类型的应用，分别为汽车对汽车(vehicle to vehicle，V2V)、汽车对基础设施(vehicle to infrastructure，V2I)、汽车对网络(vehicle to network，V2N)、和汽车对行人(vehicle to pedestrian，V2P)等。通过这4种应用，车辆、路边的基础设施、应用服务器和行人等可收集、处理和分享周边车辆和环境的状态信息，以提供更智能化的服务，如无人驾驶(unmanned driving)、自动驾驶(automated driving)、辅助驾驶(driver assistance)、智能驾驶(intelligentdriving)、网联驾驶(connected driving)、智能网联驾驶(intelligent networkdriving)、和汽车共享(car sharing)等。
可选的，在上述图1所示的通信系统100中还可以包括网络设备(网络侧设备)102。其中，网络侧设备102与终端设备101之间的通信接口为Uu空口。其中，网络设备102可以在网络设备控制器(未示出)，如基站控制器(base station controller，BSC)的控制下，通过Uu空口与终端设备101通信。
本公开实施例中的网络侧设备102是网络侧的一种用于发射或接收信号的实体。例如，网络侧设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对基站所采用的具体技术和具体设备形态不做限定。本公开实施例提供的基站可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将基站，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备101是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的一种CBR的确定方法和装置进行详细地介绍。
为了支持终端设备与终端设备之间的直接通信，引入了sidelink通信方式，终端设备与终端设备之间的接口为PC-5。根据发送和接收终端设备的对应关系，在sidelink上支持三种传输方式，单播，组播和广播。
Sidelink通信有两种发送资源分配方式，一种是网络侧设备动态调度的方式(mode 1)，另一种是终端设备在网络侧设备广播的资源池中自主选择的方式(mode 2)。其中动态调度是网络侧设备根据终端设备的缓存数据上报，动态给终端设备分配sidelink上的发送资源，而自主选择是终端设备自行在网络侧设备广播或者预配置的资源池中随机选择发送资源。具体使用哪种分配方式是网络侧设备通过RRC(Radio Resource Control,无线资源控制)信令配置的。
CBR(channel busy ratio，信道占用率)是衡量一个频段上的子信道(sub-channel)被占用情况的一个参数，终端设备在发送资源池上根据网络侧设备的配置进行CBR测量，CBR的测量值越低表明占用该资源池的子信道进行数据发送的UE越少，选择这个资源池发数据的冲突性越低。其中，LTE V2X里一个载波上可以支持一个(发送)资源池，NR Sidelink里一个载波上可以支持一个或多个(发送)资源池，UE可以分别在多个发送资源池上进行CBR的测量。
针对相关技术中，终端设备在资源池上进行CBR的测量，得到的为资源池的CBR，如何在载波选择和/或载波重选的过程中确定载波的CBR的问题。
本公开实施例中，提供一种CBR的确定方法和装置，终端设备在满足触发进行载波选择或载波重选的条件的情况下，确定资源池对应的CBR，其中，一个载波激活的部分带宽BWP上配置有至少一个资源池，根据资源池对应的CBR，确定载波的CBR，能够在载波选择和/或载波重选的过程中确定载波的CBR。
需要说明的是，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行，本公开实施例并不对此作出限定。
请参见图2，图2是本公开实施例提供的一种信道占用率CBR的确定方法的流程图。
如图2所示，该方法由终端设备执行，该方法可以包括但不限于如下步骤：
S21：响应于满足触发进行载波选择或载波重选的条件，终端设备在载波的激活的BWP上配置的资源池上进行CBR测量得到CBR测量结果，确定资源池对应的CBR，其中，一个载波激活的BWP上配置有至少一个资源池。
S22：根据资源池对应的CBR，确定载波的CBR。
可以理解的是，为了满足单用户峰值速率和系统容量提升的要求，提出了增加系统传输带宽的方法，例如：CA(Carrier Aggregation，载波聚合)。CA技术可以将多个载波(ComponentCarrier，CC)聚合在一起，能够有效提高上下行传输速率。
本公开实施例中，LTE V2X或者NR V2X或者其他通信系统的V2X支持侧链路载波聚合，针对自主选择资源的传输方式，终端设备可以进行数据发送的载波的载波选择和/或载波重选。
其中，触发进行载波选择的条件，可以为触发资源选择的条件，或者还可以为其他任意需要进行载波选择的条件；触发载波重选的条件，可以为触发资源重选的条件，或者还可以为其他任意需要进行载波重选的条件，本公开实施例对此不作具体限制。
本公开实施例中，终端设备的HARQ(hybrid automatic repeat request，混合自动重传请求)进程可以触发终端设备进行载波选择；终端设备的HARQ进程可以触发终端设备进行载波重选。
在一些可能的实现方式中，NR V2X和/或其他通信系统的V2X中一个载波激活一个BWP(Bandwidth Part，部分带宽)，且一个BWP上配置有一个资源池。
在此情况下，终端设备在满足触发进行载波选择或载波重选的条件的情况下，可以对该一个资源池进行CBR的测量，以确定资源池对应的CBR，其中，一个载波激活的BWP上配置有一个资源池，进而根据资源池对应的CBR确定载波的CBR，可以确定载波的CBR为该一个资源池对应的CBR。由此，可以在载波选择和/或载波重选的过程中确定载波的CBR。
在另一些可能的实现方式中，例如，NR V2X中一个载波激活一个BWP，且一个BWP上配置有多个资源池，或者NR V2X和/或其他通信系统的V2X中一个载波激活多个BWP，且一个BWP上配置有一个资源池。
在此情况下，一个载波对应多个资源池，终端设备在满足触发进行载波选择或载波重选的条件的情况下，终端设备可以对每一个资源池进行CBR的测量，在得到多个资源池对应的CBR的基础上，取其中的最大值/最小值/平均值/任一个/指定一个/其中部分的最大值/其中部分的最小值/其中部分的平均值，等等，确定为载波的CBR。由此，可以在载波选择和/或载波重选的过程中确定载波的CBR。
通过实施本公开实施例，终端设备响应于满足触发进行载波选择或载波重选的条件，确定资源池对应的CBR，其中，一个载波激活的BWP上配置有至少一个资源池；根据资源池对应的CBR，确定载波的CBR。由此，终端设备可以在载波选择和/或载波重选的过程中确定载波的CBR。

需要说明的是，终端设备可以基于实现确定选择的资源池对应的CBR个数N，或者还可以根据网络侧设备的指示确定选择的资源池对应的CBR个数N，或者根据预配置确定选择的资源池对应的CBR个数N，本公开实施例对此不作具体限制。
在一些实施例中，终端设备随机从所有测量的资源池对应的CBR中选择N个，包括：接收网络侧设备发送的第一指示信息，其中，第一指示信息用于指示随机从所有资源池对应的CBR中选择的个数N；根据第一指示信息，确定随机从所有测量的资源池对应的CBR中选择N个。

示例性地，N为2，终端设备接收网络侧设备发送的第一指示信息，其中，第一指示信息用于指示随机从所有资源池对应的CBR中选择的个数2；根据第一指示信息，确定随机从所有资源池对应的CBR 中选择2个。
本公开实施例中，终端设备在激活的BWP上配置的资源池上进行CBR测量得到CBR测量结果，可以根据资源池对应的CBR，确定载波的CBR，确定资源池中的一个默认资源池，确定默认资源池对应的CBR为载波的CBR。
需要说明的是，终端设备可以基于实现确定一个默认资源池，或者还可以根据网络侧设备的指示确定一个默认资源池，本公开实施例对此不作具体限制。
在一些实施例中，终端设备确定资源池中的一个默认资源池，包括：接收网络侧设备发送的第二指示信息，其中，第二指示信息用于指示默认资源池；根据第二指示信息，确定默认资源池。
本公开实施例中，终端设备确定资源池中的一个默认资源池，可以基于网络侧设备的指示确定一个默认资源池，示例性地，终端设备接收网络侧设备发送的第二指示信息，第二指示信息用于指示默认资源池，终端设备可以根据第二指示信息，确定默认资源池。
在一些可能的实现方式中，在载波激活一个BWP，一个BWP配置有多个资源池的情况下，网络侧设备发送的第二指示信息可以指示BWP配置的多个资源池中的一个资源池作为默认资源池。
示例性地，第二指示信息可以指示BWP配置的多个资源池中的一个资源池的标识，例如：资源池索引(Resource pool index)，用于指示终端设备在BWP配置的多个资源池中的一个默认资源池。
示例性地，第二指示信息还可以指示资源池是否为默认资源池，例如：可以在资源池配置中指示该资源池是否为默认资源池，例如通过新增或复用相关指示参数，在指示参数为第一特定值时，指示该资源池为默认资源池，在指示参数为非第一特征值或第二特征值时，指示该资源池不是默认资源池。例如：指示参数设置为1时，表明该资源池是默认资源池，在该指示参数不为1或者为0时，表明该资源池不是默认资源池。例如：指示参数设置为使能时，表明该资源池是默认资源池，在该指示参数为去使能时，表明该资源池不是默认资源池。
在另一些实施例中，终端设备确定资源池中的一个默认资源池；在默认资源池上进行CBR测量，确定默认资源池对应的CBR，确定默认资源池对应的CBR为载波的CBR。
本公开实施例中，终端设备确定载波激活的BWP上配置的至少一个资源池中的一个默认资源池的方法，可以参见上述实施例中的相关描述，此处不再赘述。
本公开实施例中，终端设备在确定资源池中的一个默认资源池的基础上，可以在该默认资源池上进行CBR测量，确定默认资源池对应的CBR，并且确定默认资源池对应的CBR为载波的CBR。
可以理解的是，LTE V2X支持侧链路载波聚合，针对自主选择资源的传输方式，终端设备可以进行发送载波的载波选择和/或载波重选，LTE V2X中，CBR被选为载波选择和/或载波重选的一个粒度并且引入一个重选门限(threshCBR-FreqReselection)，当触发了载波选择或者载波重选，终端设备通过比较某个载波上测量的CBR和配置的重选门限之间的大小，来确定某个载波是否可以作为候选载波。其中，该重选门限可以按优先级粒度进行配置，也就是说不同优先级关联的重选门限可以相同也可以不同，取决于网络侧设备的配置。
LTE V2X中，资源重选的触发条件就是载波重选的触发条件，但是载波重选不意味着一定要“重选”到新的载波上，如果当前载波比较合适，终端设备可以继续“保持”这个载波。因此为了实现这个目标，LTE V2X中引入另外一个保持门限(threshCBR-FreqKeeping)，当触发了载波重选，终端设备通过比较当前触发载波重选的载波的测量CBR和配置的保持门限之间的大小，来确定是否可以重选到当前触发重选的载波上。该保持门限也可以按优先级粒度进行配置，也就是说不同优先级关联的保持门限可以相同也可以不同，取决于网络侧设备的配置。
在一些实施例中，终端设备接收网络侧设备发送的配置信息，其中，配置信息用于指示进行载波选择或载波重选的重选门限，和/或进行载波选择或载波重选的保持门限；根据配置信息，确定进行载波选择或载波重选的重选门限，和/或进行载波选择或载波重选的保持门限。
