下面先结合附图1，对应用于终端设备的副链路资源确定方法进行说明。
图1示出了根据本公开一个实施例的副链路资源确定方法，应用于终端设备。如图1所示，该方法可以包括如下步骤：
步骤101、基于预设信息和预设参数中的至少一种，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
其中，所述预设信息包括所述终端设备的Uu接口使用的资源的相关信息和承载所述目标SL资源的载波的属性中的任一种；所述预设参数包括所述候选SL资源的利用率和所述候选SL资源的通信质量参数中的至少一种。Uu接口指的是用户到网络的通用(User to Network interface universal，Uu)接口。下文中会结合具体的实施方式对上述预设信息进行更为详细的说明，详见下文。
目标SL业务，可以是一个终端设备通过副链路(Sidelink，SL)发现另一终端设备的业务(以下简称发现业务)，或者可以是一个终端设备SL向另一终端设备传输数据的业务(以下简称传输业务)。
候选SL资源，可以是由网络侧预先配置的用于SL业务的资源池(pool)中的资源。一般而言，网络侧给终端设备预先配置的用于SL业务的资源池中除了包含发现业务或传输业务所用的资源，还可以包含与传输业务相关的参 数。例如，还可以包含资源池的第一个子帧的偏移值、资源池对应的比特位图(bitmap)、是否会在相邻资源块(Resource Block，RB)传输物理副链路控制信道(Physical Sidelink Control Channel,PSCCH)和物理副链路共享信道(Physical Sidelink Shared Channel,PSSCH)、子信道的数量和每个子信道的大小以及子信道对应的最低RB索引值、PSCCH资源池对应的最低RB索引值、信道占用率(Channel Busy Rate，CBR)测量的副链路接收信号强度指示器(Sidelink Received Signal Strength Indicator，SL-RSSI)门限、区域标识等参数。
可选地，网络侧给终端设备配置的用于SL业务的资源池，除了普通资源池，还可以配置一个异常资源池(exceptional pool))，异常资源池用于一些特殊的情况，如应用于使用资源切换、无线链路失败(Radio Link Failure，RLF)、从空闲(IDLE)向连接(CONNECTED)状态转换等过程中。
目标SL资源，是处理目标SL业务需要使用的SL资源。
在实际应用中，终端设备可以在准备处理目标SL业务时，或者，终端设备在基于其他方式为目标SL业务确定的目标SL资源不满足需求，需要重新确定针对目标SL业务的目标SL资源时，执行上述步骤101。
在本公开实施例中，终端设备是在考虑了Uu接口使用的资源的相关信息、承载目标SL资源的载波的属性、候选SL资源的利用率和候选SL资源的通信质量参数中的至少一个因素的影响的基础上，确定的针对目标SL业务的目标SL资源，因此，可以改善终端设备中的SL资源的利用情况，能使终端设备更合理、更好地使用SL资源。
下面结合具体的实施方式对本公开实施例提供的副链路资源确定方法进行说明。
在第一种具体实施方式中，步骤101可以包括：基于预设信息，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
作为一个例子，在上述第一种具体实施方式中，步骤101中的候选SL资源包括分别位于增补上行链路(Supplement UpLink，SUL)载波上和非SUL载波上且具有相同服务质量(Quality of Service，QoS)参数的SL资源，所述预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括 所述Uu接口使用的SL资源的信息。
如果网络侧给一个小区(cell)配置两个上行载波，其中的一个为普通载波(或称非SUL载波)，另一个即为SUL载波。一般情况下，SUL载波的覆盖性能比非SUL载波的覆盖性能号，SUL载波可以用来提高NR系统的载波覆盖。
其中，QoS参数，具体可以包括但不限于以下参数中的一种或多种：业务优先级、数据包或数据流时延(latency)、数据包或数据流的可靠性(Reliability)、数据包或数据流的通信距离(communication range)、数据包或数据流的大小(payload)、数据包或数据流的发送速率(communication range)、数据包或数据流的数据速率(Data rate)。
相应的，步骤101具体可以包括：基于所述预设信息，将所述候选SL资源中被所述Uu接口使用的SL资源，确定为所述目标SL资源。
具体的，如果所述Uu接口使用的SL资源为所述SUL载波，则将所述SUL载波确定为所述目标SL资源；如果所述Uu接口使用的SL资源为所述非SUL载波，则将所述非SUL载波确定为所述目标SL资源。
该例子意在说明，如果为一个小区配置的SUL载波和非SUL载波上存在QoS相同的SL资源，那么终端设备可以考虑Uu接口当前工作在SUL载波上还是非SUL载波上，来确定目标SL资源。具体是将Uu接口当前工作的载波上的SL资源确定为目标SL资源，这样可以减少载波的切换，提高通信效率。
作为另一个例子，在上述第一种具体实施方式中，步骤101中的预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括所述Uu接口所使用的SL资源的激活或去激活的信息。
相应的，步骤101具体可以包括：基于所述预设信息，将所述候选SL资源中被所述Uu接口使用且处于激活状态的SL资源确定为所述目标SL资源。
更为具体的，可以将所述候选SL资源中被所述Uu接口使用且处于激活状态的辅小区(Secondary cell，Scell)或带宽部分(bandwidth part，BWP)对应的SL资源，确定为所述目标SL资源。
该例子意在说明，由于位于不同载波上的Scell或BWP存在激活或去激活两个不同的状态，因此，如果SL资源和Uu接口使用的载波位于同一载波上，形成混合载波，那么可以基于Uu接口使用的资源是否被激活或去激活，来确定目标SL资源，具体的可以将候选SL资源中被Uu接口使用且处于激活状态的辅小区Scell或带宽部分BWP对应的SL资源，确定为所述目标SL资源。这样可以减少终端设备的射频变化(Radio frequency change，RF change)。
作为另一个例子，在上述第一种具体实施方式中，步骤101中的预设信息包括所述Uu接口使用的资源的相关信息，所述相关信息包括所述Uu接口使用的资源对候选SL资源产生的干扰的信息。
相应的，步骤101具体可以包括：基于所述预设信息，将所述候选SL资源中由所述Uu接口使用的资源带来的干扰的程度小于第一阈值的SL资源，确定为所述目标SL资源。
其中，Uu接口使用的资源对候选SL资源产生的干扰可以是谐波、焦调或邻频泄露等。
该例子旨在说明，由于Uu接口在某一频率的资源上工作(例如发送或接收数据)时，会对在另一频率的资源产生干扰，因此，可以基于所述Uu接口使用的资源给候选SL资源带来的干扰的程度的高低，来确定目标SL资源，具体可以将所述Uu接口使用的资源给候选SL资源带来的干扰的程度小于一定门限的候选SL资源，确定为目标SL资源。这样可以降低终端设备使用目标SL资源处理目标SL业务时受到的干扰，保证目标SL业务被顺利处理。
作为又一个例子，在上述第一种具体实施方式中，步骤101中的候选SL资源可以包括所述终端设备支持的不同无线接入技术(Radio Access Technology，RAT)对应的SL资源池中的资源，所述预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括所述Uu接口选用的RAT的信息。
相应的，步骤101具体可以包括：基于所述预设信息，确定所述Uu接口选用的目标RAT；从所述候选SL资源中所述目标RAT对应的SL资源池中，确定所述目标SL资源。
在该例子中，基于Uu接口当前选用的RAT，来确定目标SL资源，这可以避免出现确定出的目标SL资源对应的RAT与Uu接口当前选用的RAT不一致，需要进行RAT切换的现象。
作为再一个例子，在上述第一种具体实施方式中，步骤101中的预设信息包括承载所述目标SL资源的载波的属性，且本公开实施例提供的一种副链路资源确定方法，还可以包括：基于所述终端设备的特征信息和所述目标SL业务的特征信息中的至少一种，确定承载所述目标SL资源的载波的属性。
其中，载波的属性可以用子载波间隔(SubCarrier Spacing，SCS)或BWP来表征。终端设备的特征信息可以包括但不限于所述终端设备的移动速度。其中，目标SL业务的特征信息可以包括但不限于所述目标SL业务的优先级信息和承载所述目标SL业务的逻辑信道信息中的任一种。
举例来说，一般情况下，如果载波的属性用SCS表征，那么终端设备的移动速度越快或者目标SL业务的优先级越高，相应的确定出的目标SL资源的载波的SCS越大；如果载波的属性用BWP表征，那么终端设备的移动速度越快，相应的选择具有支持高速移动终端设备的标识的BWP作为目标SL资源的载波的属性。在实际应用中，可以预先建立终端设备的特征信息或目标SL业务的特征信息与承载目标SL资源的载波的属性的对应关系，然后基于该对应关系，确定承载目标SL资源的载波的属性。
相应的，上述步骤101可以包括：基于所述预设信息，将所述候选SL资源中具有所述属性的SL资源，确定为所述目标SL资源。
在该例子中，是基于承载目标SL资源的载波的属性，确定目标SL资源，这可以满足特定SL业务或特定逻辑信道上承载的SL业务需要使用特定SL资源的需求。
在第二种具体实施方式中，步骤101可以包括：基于预设信息和预设参数，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
例如，如图2所示，步骤101可以包括如下子步骤：
子步骤201、基于所述预设信息，从所述候选SL资源中确定针对所述目标SL业务的第一SL资源。
需要说明的是，子步骤201中确定第一SL资源的方式与上文所述的第一 种具体实施方式中确定目标SL资源的方式对应一致，为避免重复，此处不再赘述。
子步骤202、在所述第一SL资源的预设参数与第二SL资源的预设参数满足第一预设条件时，将所述第二SL资源确定为所述目标SL资源，所述第二SL资源为所述候选SL资源中的SL资源。
可选的，如果所述第一SL资源的预设参数与第二SL资源的预设参数不满足上述第一预设条件时，则将所述第一SL资源确定为所述目标SL资源。
在该实施方式中，第二SL资源是候选SL资源中与第一SL资源不同的资源，也即第二SL资源是未被选作第一SL资源的候选SL资源。作为一个例子，第二SL资源可以是候选SL资源中除第一SL资源外的部分或全部SL资源。
如前文所述，预设参数可以包括但不限于所述候选SL资源的利用率和所述候选SL资源的通信质量参数中的至少一种。
相应的，在一个例子中，如果预设参数包括所述候选SL资源的利用率，那么子步骤202可以包括：在所述第一SL资源的利用率比所述第二SL资源的利用率高第二阈值时，将所述第二SL资源确定为所述目标SL资源。
其中，资源的利用率可以基于信道占用率(Channel Busy Rate，CBR)来确定。相应的，在该例子中，当资源的利用率用CBR表征时，则可以在第一SL资源的CBR比第二SL资源的CBR高第二阈值时，将所述第二SL资源确定为所述目标SL资源。
具体如，假设第一SL资源的CBR等于a，第二SL资源的CBR等于b，第二阈值为c时，则在a-b＞c，其中，a、b、c均大于或等于0。
由于资源的利用率反映了资源的繁忙程度，一个资源的利用率越高(CBR越大)，说明该资源越繁忙，反之越不繁忙。因此，可以理解，该例子意在说明，在基于子步骤201确定出针对目标SL业务的第一SL资源之后，并不直接将第一SL资源作为目标SL资源，而是需要进一步地确定候选SL资源中未被选作第一SL资源的SL资源的繁忙程度是不是更低，如果第一SL资源相比于第二SL资源很繁忙，则选择第二SL资源作为目标SL资源；否则，才将第一SL资源作为目标SL资源。以使最终确定的目标SL资源能够保证 目标SL业务被更好地处理。
在另一个例子中，如果预设参数包括所述候选SL资源的通信质量参数，那么子步骤202可以包括：在所述第一SL资源的通信质量参数比所述第二SL资源的通信质量参数低第三阈值时，将所述第二SL资源确定为所述目标SL资源。
其中，通信质量参数可以包括但不限于参考信号接收功率(Reference Signal Receiving Power，RSRP)和参考信号接收质量(Reference Signal Received Quality，RSRQ)。
具体如，假设第一SL资源的通信质量参数等于d，第二SL资源的通信质量参数等于e，第三阈值为f时，则在e-d＞f，其中，a、b、c均大于或等于0。
由于通信质量参数反映了资源的性能，一个资源的通信质量参数越高，说明该资源的性能越好，反之越不好。因此，可以理解，该例子意在说明，在基于子步骤201确定出针对目标SL业务的第一SL资源之后，并不直接将第一SL资源作为目标SL资源，而是需要进一步地确定候选SL资源中未被选作第一SL资源的SL资源的性能是不是更优，如果第一SL资源相比于第二SL资源性能较差，则选择第二SL资源作为目标SL资源；否则，才将第一SL资源作为目标SL资源。以使最终确定的目标SL资源能够保证目标SL业务被更好地处理。
在第三种具体实施方式中，步骤101可以包括：基于预设参数，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
具体的，步骤101可以包括：将所述候选SL资源中所述预设参数满足第二预设条件的SL资源，确定为所述目标SL资源。
例如，如果所述预设参数为候选SL资源的利用率，则可以将所述候选SL资源中利用率最低或者低于某一阈值的SL资源，确定为所述目标SL资源。
再如，如果所述预设参数为候选SL资源的通信质量参数，则可以将所述候选SL资源中通信质量参数最高或者高于某一阈值的SL资源，确定为所述目标SL资源。
以上对应用于终端设备的副链路资源确定方法进行了说明，下面将结合图3至图4详细描述根据本公开实施例的终端设备。
图3示出了本公开实施例提供的一种终端设备的结构示意图，如图3所示，终端设备300包括：资源确定模块301。
资源确定模块301，用于基于预设信息和预设参数中的至少一种，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
其中，所述预设信息包括所述终端设备的Uu接口使用的资源的相关信息和承载所述目标SL资源的载波的属性中的任一种；所述预设参数包括所述候选SL资源的利用率和所述候选SL资源的通信质量参数中的至少一种。
在本公开实施例中，终端设备是在考虑了Uu接口使用的资源的相关信息、承载目标SL资源的载波的属性、候选SL资源的利用率和候选SL资源的通信质量参数中的至少一个因素的影响的基础上，确定的针对目标SL业务的目标SL资源，因此，可以改善终端设备中的SL资源的利用情况，能使终端设备更合理、更好地使用SL资源。
下面结合具体的实施方式对本公开实施例提供的终端设备300进行说明。
在第一种具体实施方式中，终端设备300中的资源确定模块301，可以用于基于预设信息，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
作为一个例子，在上述第一种具体实施方式中，资源确定模块301的候选SL资源包括分别位于SUL载波上和非SUL载波上且具有相同QoS参数的SL资源，所述预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括所述Uu接口使用的SL资源的信息。
相应的，资源确定模块301具体可以用于：基于所述预设信息，将所述候选SL资源中被所述Uu接口使用的SL资源，确定为所述目标SL资源。
具体的，如果所述Uu接口使用的SL资源为所述SUL载波，则将所述SUL载波确定为所述目标SL资源；如果所述Uu接口使用的SL资源为所述非SUL载波，则将所述非SUL载波确定为所述目标SL资源。
该例子意在说明，如果为一个小区配置的SUL载波和非SUL载波上存在QoS相同的SL资源，那么终端设备可以考虑Uu接口当前工作在SUL载 波上还是非SUL载波上，来确定目标SL资源。具体是将Uu接口当前工作的载波上的SL资源确定为目标SL资源，这样可以减少载波的切换，提高通信效率。
作为另一个例子，在上述第一种具体实施方式中，资源确定模块301中的预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括所述Uu接口所使用的SL资源的激活或去激活的信息。
相应的，资源确定模块301具体可以用于：基于所述预设信息，将所述候选SL资源中被所述Uu接口使用且处于激活状态的SL资源确定为所述目标SL资源。
更为具体的，可以将所述候选SL资源中被所述Uu接口使用且处于激活状态的Scell或BWP对应的SL资源，确定为所述目标SL资源。
该例子意在说明，由于位于不同载波上的Scell或BWP存在激活或去激活两个不同的状态，因此，如果SL资源和Uu接口使用的载波位于同一载波上，形成混合载波，那么可以基于Uu接口使用的资源是否被激活或去激活，来确定目标SL资源，具体的可以将候选SL资源中被Uu接口使用且处于激活状态的辅小区Scell或带宽部分BWP对应的SL资源，确定为所述目标SL资源。这样可以减少终端设备的射频变化(Radio frequency change，RF change)。
作为另一个例子，在上述第一种具体实施方式中，资源确定模块301中的预设信息包括所述Uu接口使用的资源的相关信息，所述相关信息包括所述Uu接口使用的资源对候选SL资源产生的干扰的信息。
相应的，资源确定模块301具体可以用于：基于所述预设信息，将所述候选SL资源中由所述Uu接口使用的资源带来的干扰的程度小于第一阈值的SL资源，确定为所述目标SL资源。
其中，Uu接口使用的资源对候选SL资源产生的干扰可以是谐波、焦调或邻频泄露等。
该例子旨在说明，由于Uu接口在某一频率的资源上工作(例如发送或接收数据)时，会对在另一频率的资源产生干扰，因此，可以基于所述Uu接口使用的资源给候选SL资源带来的干扰的程度的高低，来确定目标SL资源，具体可以将所述Uu接口使用的资源给候选SL资源带来的干扰的程度小 于一定门限的候选SL资源，确定为目标SL资源。这样可以降低终端设备使用目标SL资源处理目标SL业务时受到的干扰，保证目标SL业务被顺利处理。
作为又一个例子，在上述第一种具体实施方式中，资源确定模块301中的候选SL资源可以包括所述终端设备支持的不同无线接入技术RAT对应的SL资源池中的资源，所述预设信息包括所述Uu接口使用的资源的相关信息，且所述相关信息包括所述Uu接口选用的RAT的信息。
相应的，资源确定模块301具体可以用于：基于所述预设信息，确定所述Uu接口选用的目标RAT；从所述候选SL资源中所述目标RAT对应的SL资源池中，确定所述目标SL资源。
在该例子中，基于Uu接口当前选用的RAT，来确定目标SL资源，这可以避免出现确定出的目标SL资源对应的RAT与Uu接口当前选用的RAT不一致，需要进行RAT切换的现象。
作为再一个例子，在上述第一种具体实施方式中，资源确定模块301中的预设信息包括承载所述目标SL资源的载波的属性，且本公开实施例提供的一种副链路资源确定方法，还可以包括：基于所述终端设备的特征信息和所述目标SL业务的特征信息中的至少一种，确定承载所述目标SL资源的载波的属性。
其中，载波的属性可以用SCS或BWP来表征。终端设备的特征信息可以包括但不限于所述终端设备的移动速度。其中，目标SL业务的特征信息可以包括但不限于所述目标SL业务的优先级信息和承载所述目标SL业务的逻辑信道信息中的任一种。
举例来说，一般情况下，如果载波的属性用SCS表征，那么终端设备的移动速度越快或者目标SL业务的优先级越高，相应的确定出的目标SL资源的载波的SCS越大；如果载波的属性用BWP表征，那么终端设备的移动速度越快，相应的选择具有支持高速移动终端设备的标识的BWP作为目标SL资源的载波的属性。在实际应用中，可以预先建立终端设备的特征信息或目标SL业务的特征信息与承载目标SL资源的载波的属性的对应关系，然后基于该对应关系，确定承载目标SL资源的载波的属性。
相应的，上述资源确定模块301可以用于：基于所述预设信息，将所述候选SL资源中具有所述属性的SL资源，确定为所述目标SL资源。
在该例子中，是基于承载目标SL资源的载波的属性，确定目标SL资源，这可以满足特定SL业务或特定逻辑信道上承载的SL业务需要使用特定SL资源的需求。
在第二种具体实施方式中，资源确定模块301可以用于：基于预设信息和预设参数，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
例如，如图4所示，资源确定模块301可以包括如下子模块：
第一确定子模块401，用于基于所述预设信息，从所述候选SL资源中确定针对所述目标SL业务的第一SL资源。
需要说明的是，第一确定子模块401中确定第一SL资源的方式与上文所述的第一种具体实施方式中确定目标SL资源的方式对应一致，为避免重复，此处不再赘述。
第二确定子模块402，用于在所述第一SL资源的预设参数与第二SL资源的预设参数满足第一预设条件时，将所述第二SL资源确定为所述目标SL资源，所述第二SL资源为所述候选SL资源中的SL资源。
可选的，如果所述第一SL资源的预设参数与第二SL资源的预设参数不满足上述第一预设条件时，则将所述第一SL资源确定为所述目标SL资源。
在该实施方式中，第二SL资源是候选SL资源中与第一SL资源不同的资源，也即第二SL资源是未被选作第一SL资源的候选SL资源。作为一个例子，第二SL资源可以是候选SL资源中除第一SL资源外的部分或全部SL资源。
如前文所述，预设参数可以包括但不限于所述候选SL资源的利用率和所述候选SL资源的通信质量参数中的至少一种。
相应的，在一个例子中，如果预设参数包括所述候选SL资源的利用率，那么第二确定子模块402可以用于：在所述第一SL资源的利用率比所述第二SL资源的利用率高第二阈值时，将所述第二SL资源确定为所述目标SL资源。
其中，资源的利用率可以基于CBR来确定。
由于资源的利用率反映了资源的繁忙程度，一个资源的利用率越高(CBR越大)，说明该资源越繁忙，反之越不繁忙。因此，可以理解，该例子意在说明，在基于第一确定子模块401确定出针对目标SL业务的第一SL资源之后，并不直接将第一SL资源作为目标SL资源，而是需要进一步地确定候选SL资源中未被选作第一SL资源的SL资源的繁忙程度是不是更低，如果第一SL资源相比于第二SL资源很繁忙，则选择第二SL资源作为目标SL资源；否则，才将第一SL资源作为目标SL资源。以使最终确定的目标SL资源能够保证目标SL业务被更好地处理。
在另一个例子中，如果预设参数包括所述候选SL资源的通信质量参数，那么第二确定子模块402可以用于：在所述第一SL资源的通信质量参数比所述第二SL资源的通信质量参数低第三阈值时，将所述第二SL资源确定为所述目标SL资源。
其中，通信质量参数可以包括但不限于RSRP和RSRQ。
由于通信质量参数反映了资源的性能，一个资源的通信质量参数越高，说明该资源的性能越好，反之越不好。因此，可以理解，该例子意在说明，在基于第一确定子模块401确定出针对目标SL业务的第一SL资源之后，并不直接将第一SL资源作为目标SL资源，而是需要进一步地确定候选SL资源中未被选作第一SL资源的SL资源的性能是不是更优，如果第一SL资源相比于第二SL资源性能较差，则选择第二SL资源作为目标SL资源；否则，才将第一SL资源作为目标SL资源。以使最终确定的目标SL资源能够保证目标SL业务被更好地处理。
在第三种具体实施方式中，资源确定模块301可以用于：基于预设参数，从候选副链路SL资源中确定针对目标SL业务的目标SL资源。
具体的，资源确定模块301可以用于：将所述候选SL资源中所述预设参数满足第二预设条件的SL资源，确定为所述目标SL资源。
例如，如果所述预设参数为候选SL资源的利用率，则可以将所述候选SL资源中利用率最低或者低于某一阈值的SL资源，确定为所述目标SL资源。
再如，如果所述预设参数为候选SL资源的通信质量参数，则可以将所述 候选SL资源中通信质量参数最高或者高于某一阈值的SL资源，确定为所述目标SL资源。
