旁链路(Sidelink)是指终端设备(User Equipment，UE)和UE之间不通过网络进行直连通信的链路。长期演进(Long Term Evolution，LTE)Sidelink包括设备到设备(Device to Device，D2D)通信、车联网(Vehicle to Everything，V2X)通信。新空口(New Radio，NR)Sidelink目前包括V2X通信。在LTE Sidelink中支持两种资源分配模式：调度资源分配模式和UE自主资源选择模式。调度资源分配模式下，网络设备为Sidelink配置资源；UE自主资源选择模式下，UE会基于一段时间的监测结果，周期性的预留一定的资源。
相关技术中，UE在进行资源监测的过程中依据的参数值为固定值，影响UE选择到合适资源的概率，不利于平衡UE的可靠性和系统的丢包率。

以下结合附图，详细说明本公开各实施例提供的技术方案。
图1示出了根据本公开一个实施例的确定参数值的方法。图1所示的方法可以由旁链路Sidelink通信中的终端设备执行。如图1所示，方法包括：
S110，若当前时刻为参数值调整时刻，则根据目标方式确定目标参数在所述当前时刻的目标数值，所述目标参数包括干扰门限、信号强度门限、信道占用率门限、信道忙率门限和距离门限中的至少一种，所述目标方式为以下方式中的一种：
根据目标映射关系确定所述目标数值，所述目标映射关系包括所述目标参数的值与第一目标信息之间的映射关系，所述第一目标信息包括目标时长、目标时长比例、计数器的值和重传次数中的至少一种；以及
根据所述目标参数的初始值和数值调整步长，确定所述目标数值，其中，所述目标参数的初始值与所述第一目标信息相关。
可以理解的是，在S110中的目标时长、计数器的值和重传次数实际上是随时间变化的值。目标参数在当前时刻的目标数值的有效时间段可以为该目标数值的生效时刻与目标参数在下一个调整时刻的值的生效时刻之间的时间段。
可选地，作为一个例子，S110中的计数器可以用于资源分配。
可选地，在一些实施例中，目标方式为根据目标映射关系确定所述目标数值；其中，所述第一目标信息包括目标时长或目标时长比例，所述目标时长包括第一时长或第二时长，所述第一时长为计时开始时刻与所述当前时刻之间的时长，所述第二时长为所述当前时刻与满足传输时延需求的最晚时刻之间的时长，所述终端设备在所述第一时长内未进行信息传输，所述目标时长比例为所述计时开始时刻与所述当前开始时刻之间的时长与时延需求的比值。
在目标方式为根据目标映射关系确定所述目标数值，所述第一目标信息包括目标时长的情况下，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻，或者根据目标时长和预设时长，确定当前时刻是否为参数调整时刻。在目标方式为根据目标映射关系确定所述目标数值，所述第一目标信息包括目标时长比例的情况下，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻，或者根据目标时长比例和预设时长比例，确定当前时刻是否为参数调整时刻。例如，时延需求为100ms，预设时长比例为40％，则当已经过去的时间为40ms时，触发参数调整。
这里的计时开始时刻可以为以下时刻中的一种：数据包的到达时刻、第二目标信息的接收时刻和第二目标信息指示的时刻；在终端设备为发送端终端设备时，第二目标信息包括以下信息中的至少一种：高层信令、下行控制信息(Downlink Control Information，DCI)和旁链路控制信息(Sidelink Control Information，SCI)；在终端设备为接收端终端设备时，第二目标信息包括以下信息中的至少一种：高层信令、DCI、调度请求(Scheduling Request，SR)、缓存状态包括(Buffer Status Report，BSR)和SCI。这里的高层信令例如可以是无线资源控制(Radio Resource Control，RRC)信令、广播信令、旁链路广播信息或旁链路系统信息。
需要说明的是，满足传输时延需求的最晚时刻还可以理解为终端设备确定丢包的时刻。或者可以理解为与数据包的生成时刻之间的时间间隔为传输时延需求的时刻。
以第一时长和第二时长的和为时延L，目标参数为干扰测量门限或信号 强度门限为例。若第一时长为t，则第二时长res_t＝L-t，可以预定义或预配置干扰测量门限或信号强度门限与第一时长或第二时长的映射关系(映射关系可以为表格)。根据t＝0或res_t＝L与映射关系，可以得到干扰测量门限值或信号强度门限的初始值。如果当前时刻为干扰测量门限或信号强度门限的调整时刻，则可以根据当前时刻的t或res_t的值和映射关系确定出干扰门限或信号强度门限的值。
在这个例子中，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻。或者根据第一时长或第二时长，确定当前时刻是否为参数调整时刻。例如，如果在当前时刻，t大于T1，或者res_t小于T2，则当前时刻为参数调整时刻。这里调整时间粒度、T1和T2的值可以是预定义的，或者可以是预配置的，或者可以是网络设备配置的，或者可以是终端设备配置的。调整时间粒度例如可以是以下粒度中的一个：毫秒(ms)、子帧(subframe)、N个时隙(slot)、多时隙(multi-slot)、N个符号(symbol)、帧(frame)和一个时间样式(Time Pattern)，N为大于或等于1的正整数。
或者，以目标参数为信道占用率门限或信道忙率门限，以第一目标信息包括计数器(counter)的值为例。可以预定义或预配置信道占用率门限或信道忙率门限与计数器的值的映射关系(映射关系可以为表格)。每个参数调整时刻，根据参数调整时刻的计数器的值和映射关系，即可以确定出每个参数调整时刻的信道占有率门限的值或信道忙率的值。在这个例子中，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻。
或者，以目标参数为距离门限，以第一目标信息包括重传次数为例。可以预定义或预配置距离门限与重传次数的映射关系。每个参数调整时刻，根据参数调整时刻的重传次数和映射关系，即可以确定出每个参数调整时刻的距离门限的值。在这个例子中，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻。初传可以认为对应的重传次数为0。
上述的距离门限可以理解为终端设备与终端设备之间的距离的门限。例如，一个参数调整时刻对应的重传次数为0，距离门限的值为1000米，则终端设备将与自己相距1000米以内的其他终端设备占用的资源认为是被占用的资源。下一个参数调整时刻对应的重传次数为1，距离门限的值为500米， 则终端设备将与自己相距500米以内的其他终端设备占用的资源认为是被占用资源。
可选地，在一些实施例中，目标方式为根据目标参数的初始值和数值调整步长，确定所述目标数值。图1所示的方法还包括：
根据所述第一目标信息对应的初始值以及目标参数的值与所述第一目标信息之间的映射关系，确定所述目标参数的初始值。
可以理解的是，在当前时刻为第一次对目标参数的值进行调整的参数调整时刻时，终端设备根据目标参数的初始值和数值调整步长，确定目标数值。当在当前时刻不是第一次对目标参数的值进行调整的参数调整时刻时，终端设备实际根据当前时刻之前目标参数的值和数值调整步长，确定目标参数的目标数值。
举例来说，第一目标信息包括目标时长，目标时长包括第一时长或第二时长，第一时长为计时开始时刻与当前时刻之间的时长，第二时长为当前时刻与满足传输时延需求的最晚时刻之间的时长，终端设备在所述第一时长内未进行信息传输。在这种情况下，可以根据调整时间粒度，确定当前时刻是否为参数调整时刻，或者根据目标时长和预设时长，确定当前时刻是否为参数调整时刻。
这里的计时开始时刻可以为以下时刻中的一种：数据包的到达时刻、计数器的激活时刻、第三目标信息的接收时刻和第三目标信息指示的时刻；在所述终端设备为发送端终端设备时，第三目标信息包括以下信息中的至少一种：高层信令、DCI和SCI；在所述终端设备为接收端终端设备时，第三目标信息包括以下信息中的至少一种：高层信令、DCI、SR、BSR和SCI。
以第一时长和第二时长的和为时延L，目标参数为干扰测量门限或信号强度门限为例。若第一时长为t，则第二时长res_t＝L-t，可以预定义或预配置干扰测量门限或信号强度门限与第一时长或第二时长的映射关系(映射关系可以为表格)。根据t＝0或res_t＝L与映射关系，可以得到干扰测量门限值或信号强度门限的初始值。
或者，以目标参数为信道占用率门限或信道忙率门限，以第一目标信息包括计数器(counter)的值为例。可以预定义或预配置信道占用率门限或信 道忙率门限与计数器的值的映射关系(映射关系可以为表格)。可以根据数据包的到达时刻计时器的值与映射关系，确定信道占用门限或信道忙率门限的初始值。
或者，以目标参数为距离门限，以第一目标信息包括重传次数为例。可以预定义或预配置距离门限与重传次数的映射关系。可以根据该映射关系和重传次数0，确定距离门限的初始值。
在确定出目标参数的初始值之后，可以进一步确定数值调整步长。数值调整步长可以是预配置、预定义、网络设备配置或终端设备配置的。数值调整步长也可以是基于映射关系确定的。
在一些实施例中，数值调整步长由终端设备根据目标时长和数值调整步长之间的映射关系确定。
例如，以第一时长和第二时长的和为时延L，目标参数为干扰测量门限为例。若第一时长为t，则第二时长res_t＝L-t，可以预定义或预配置干扰测量门限与第一时长的映射关系，预定义或预配置调整时间粒度为1个slot。假设t在[a,b]内，数值调整步长为3dB，在[b,c]内，数值调整步长为6dB。A＝0，b＝5，c＝50，若t＝48ms，则t在[b,c]内，则在下一个slot中，判断资源是否被预留时，干扰门限的值为当前时刻的干扰门限的值减去6dB。
在一些实施例中，所述第一目标信息中还包括频域资源单元的粒度，所述数值调整步长由所述终端设备根据所述频域资源单元的粒度和所述数值调整步长之间的映射关系确定。或者，所述数值调整步长由所述终端设备根据所述重传次数和所述数值调整步长之间的映射关系确定。这里不同次的重传对应的数值调整步长不同，能够平衡可靠性和系统拥塞。
可以理解的是，上述确定初始值和根据映射关系确定数值调整步长的方案至少包括以下技术方案：(1)根据目标时长的初始值确定目标参数的初始值，根据目标时长和数值调整步长之间的映射关系确定数值调整步长；(2)根据目标时长的初始值确定目标参数的初始值，根据频域资源单元的粒度和数值调整步长之间的映射关系确定数值调整步长；(3)根据目标时长的初始值确定目标参数的初始值，根据重传次数和数值调整步长之间的映射关系确定数值调整步长；(4)根据计数器的初始值确定目标参数的初始值，根据目 标时长和数值调整步长之间的映射关系确定数值调整步长；(5)根据计数器的初始值确定目标参数的初始值，根据频域资源单元的粒度和数值调整步长之间的映射关系确定数值调整步长；(6)根据计数器的初始值确定目标参数的初始值，根据重传次数和数值调整步长之间的映射关系确定数值调整步长；(7)根据重传次数为0确定目标参数的初始值，根据目标时长和数值调整步长之间的映射关系确定数值调整步长；(8)根据重传次数为0确定目标参数的初始值，根据频域资源单元的粒度和数值调整步长之间的映射关系确定数值调整步长；(9)根据重传次数为0确定目标参数的初始值，根据重传次数和数值调整步长之间的映射关系确定数值调整步长。
作为一个具体的例子，确定参数值的方法可以包括以下步骤：
步骤1、预定义计数器的值和优先级的映射关系，预配置参考信号接收功率(Reference Signal Receiving Power，RSRP)门限的值和第二时长的映射关系，调整时间粒度为N，数值调整步长为A。
步骤2、数据到在传输时间间隔(Transmission Time Interval，TTI)n时刻到达，根据数据包的优先级，以及计数器的值和优先级的映射关系，初始化计数器的值为M。
步骤3、若M＝0，则在当前slot上传输信息。若M>0，则判断当前TTI是否被占用。
具体在判断当前TTI是否被占用时，根据第二时长以及第二时长和RSRP门限的值的映射关系得到RSRP门限的值RSRP_thresh。
可以理解的是，TTI n对应RSRP门限的初始值RSRP_thresh_initial，在TTI n*k*N，需要调整RSRP门限的值，TTI n*k*N对应的RSRP门限的值为RSRP_thresh_initial-k*A，k＝1,2,3…floor(L/N)，L为时延。其他时刻RSRP门限的值保持不变，即除了初始化RSRP门限的值或调整RSRP的门限的值的时刻，其他时刻对应的RSRP门限的值保持和该时刻的上一个TTI一致。
在判断当前TTI是否被占用时，可以测量调度分配(Scheduling Assignment，SA)所在资源上的RSRP，若RSRP大于RSRP_thresh，则认为被占用。
步骤4、若被占用，则计数器的值保持不变，TTI+1，若未被占用，计数 器的值递减，TTI+1。
步骤5、若计数器的值小于或0，则在下一个可用的TTI发送信息，否则执行步骤3及其后续步骤。
需要说明的是，上述步骤1-5并不是对方法步骤的限定，上述步骤的先后具体以步骤之间的逻辑关系确定。
图2示出了根据本公开另一个实施例的确定参数值的方法。图2所示的方法可以由旁链路Sidelink通信中的终端设备执行。如图2所示，方法包括：
S210，判断当前时刻对应的传输资源的占用情况；
S220，若所述传输资源未被占用，则调整计数器的值，所述计数器用于资源分配。
可选地，在S210中，可以根据以下方式中的至少一种确定当前时刻对应的传输资源的占用情况：
根据调度分配SA信息，判断所述传输资源的占用情况，所述SA信息用于调度所述当前时刻对应的传输资源；
根据调度分配SA信息的测量信息，判断所述当前时刻对应的传输资源的占用情况；
根据调度分配SA信息指示的信息的测量信息，判断所述当前时刻对应的传输资源的占用情况；以及，
根据所述SA信息指示的传输资源的测量信息，判断所述当前时刻对应的传输资源的占用情况。
作为一个实施例，在S210中，根据调度分配SA信息，判断所述传输资源的占用情况，所述SA信息用于调度所述当前时刻对应的传输资源。
举例来说，解调SA得到数据包的业务优先级。如果得到的业务优先级高于待传输业务的优先级，则确定传输资源未被占用。
作为一个实施例，在S210中，根据调度分配SA信息的测量信息，判断所述当前时刻对应的传输资源的占用情况，所述SA信息用于调度所述当前时刻对应的传输资源。
举例来说，测量SA的接收信号强度指示(Received Signal Strength Indication，RSSI)，若RSSI高于门限值，则认为传输资源未被占用。并且， 可以理解的是，RSSI的门限值可以根据图1所示的方法进行调整。
作为一个实施例，在S210中，根据调度分配SA信息指示的信息的测量信息，判断所述当前时刻对应的传输资源的占用情况，所述SA信息用于调度所述当前时刻对应的传输资源；或，根据调度分配SA信息指示的传输资源的测量信息，判断所述当前时刻对应的传输资源的占用情况，所述SA信息用于调度所述当前时刻对应的传输资源。
举例来说，测量SA指示的数据的RSRP，若RSRP高于门限值，则认为传输资源未被占用。并且，可以理解的是，RSRP的门限值可以根据图1所示的方法进行调整。
在S220中，所述计数器的值的调整粒度为时域调整粒度，或所述计数器的值的调整粒度为时频域调整粒度。
这里的时域调整粒度可以是slot、ms和time-pattern中的一种，时频域调整粒度中的时域粒度slot、ms和time-pattern中的一种，时频域调整粒度中的频域粒度为子信道(sub-channel)、资源块(Resource Block，RB)、F个资源块组(Resource Block Group，RBG)中的一种。
可选地，图2所示的方法还包括：确定所述计数器的初始值。
可选地，在一些实施例中，根据服务质量(Quality of Service，QoS)需求和第一映射关系，确定所述初始值，所述第一映射关系包括所述QoS需求和初始值范围之间的映射关系。这里的QoS需求可以包括以下至少一种：优先级、时延、可靠性和业务类型。
具体地，在一些实施例中，所述根据服务质量QoS需求和第一映射关系，确定所述初始值，包括：根据所述第一映射关系，确定所述初始值所在的目标初始值范围；根据第一目标信息，从所述目标初始值范围内确定所述初始值，所述第一目标信息包括以下信息中的至少一种：终端设备的地理位置、终端设备的速度、终端设备之间的距离、预设区域范围内的终端设备密度、承载类型、业务类型、包的大小和包的到达率。这里包的到达率可以理解为数据包产生的频率。
也就是说，可以基于QoS需求确定计数器的初始值的取值范围，然后进一步根据第一目标信息从初始值范围中选择出一个值作为计数器的初始值。
举例来说，预先配置优先级和计数器的初始值的取值范围的映射关系，这里的映射关系可以是一对多、多对一或多对多的映射关系。
如果为一对多或多对多的映射关系，可以根据配置的优先级，选择计数器的初始值的取值范围，然后从取值范围中随机选择一个值作为计数器的初始值。或者根据配置的优先级，选择计数器的初始值的取值范围，然后根据终端设备的ID或终端设备的地理位置选择一个值作为计数器的初始值，由此可以使得具有相同优先级的不同终端设备对应的计数器的初始值不同。或者，根据配置的优先级，选择计数器的初始值的取值范围，然后基于DCI或SCI的指示从取值范围中选择一个值作为计数器的初始值。在这种情况下，DCI或SCI可以指示计数器的初始值在取值范围中的序号，也可以直接指示该初始值。
可选地，在一些实施例中，根据第二目标信息和第二映射关系，确定所述初始值，所述第二映射关系包括所述第二目标信息和所述初始值之间的映射关系，所述第二目标信息包括以下信息中的至少一种：服务质量QoS需求、终端设备的地理位置、终端设备的速度、终端设备之间的距离、预设区域范围对应的终端设备密度、承载类型、业务类型、包的大小和包的到达率。也就是说，可以直接根据第二目标信息和初始值的映射关系，确定出初始值。
可以理解的是，如果终端设备配置了不同类型的计数器，则每种类型的计数器的初始值均可以根据上述确定初始值的方法来确定，并且每种类型的计数器的初始值可以配置不同或相同的值，本公开实施例对此不作限定。
