为便于理解本申请实施例,下面首先对本申请实施例涉及的概念进行说明。
以下结合附图对本申请实施例进行具体说明。
图2是本申请实施例提供的无线通信的方法的一示例性流程图。
本方案中,当终端装置待发送数据的候选频域单元组中包括被其他终端装置预约的频 域单元时,该终端装置确定与该候选频域单元组对应的一个频域单元组,该一个频域单元组包括该其他终端用于发送数据的频域单元,该终端装置通过测量该一个频域单元组的能量,确定该候选频域单元组是否可以用于该终端装置发送数据。通过包括该其他终端装置发送数据的一个频域单元组确定该其他终端装置的预约资源对该终端装置的影响,从而确定是否采用该候选频域单元组发送数据,能够有效地避免干扰,保障业务的可靠性需求。
S210,确定第一时间单元中的第一频域单元和第二时间单元中的第二频域单元。
第一终端装置在第一时间单元中包括的一个或多个频域单元中,确定至少一个第一频域单元,以及,在第二时间单元中包括的一个或多个频域单元中,确定至少一个第二频域单元,其中,第一频域单元为第二终端装置在第一时间单元中用于发送数据的频域单元,也可以说,第一频域单元的集合用于第二终端装置发送数据,第二频域单元为第二终端装置在第二时间单元中预约的频域单元,也可以说,第二频域单元的集合为第二终端装置预约的频域单元的集合,其中,第一时间单元在时间上晚于第二时间单元。
例如图3所示,第一时间单元中包括3个用于第二终端装置发送数据的第一频域单元,即频域单元1、频域单元2、频域单元3,该3个第一频域单元为第一频域单元的集合。第二时间单元中,4个第二终端装置预约的第二频域单元,即频域单元3、频域单元4、频域单元5、频域单元6,该4个第二频域单元为第二频域单元的集合。
一种实施方式中,第一终端装置接收第一信息和第二信息,第一信息用于指示第一频域单元的集合,第一终端装置根据第一信息确定第一频域单元的集合,第二信息用于指示第二频域单元的集合,第一终端装置根据第二信息确定第二频域单元的集合。第一信息和第二信息可以由同一个信令承载,例如,第一信息和第二信息侧行控制信息(sidelink control information,SCI),第一信息和第二信息也可以承载在不同的信令中由第一终端装置分别接收到。
S220,确定与第二时间单元中的第二候选频域单元组相关联的第一时间单元中的第一频域单元组。
S230,根据第一频域资源确定第二频域资源是否可用。
第二时间单元为第一终端装置待发送数据的候选时间单元,第一终端装置根据待发送数据的大小确定需要的频域单元的个数,再根据需要的频域单元的个数确定第二时间单元中的一个或多个候选频域单元组。其中,在第二时间单元中的一个或多个候选频域单元组中,包括至少一个第二频域单元的候选频域单元组为第二候选频域单元组,其中,第二频域单元为第二时间单元中被另一个终端装置预约的时间单元,也就是说,第二候选频域单元组包括至少一个被第二终端装置预约的频域单元。例如图4所示,第一终端装置待发送数据需要的频域单元个数N data为2,资源池包括的全部频域单元的个数N Total为8,将每两个连续的频域单元作为一个待发送数据的候选频域单元组,则资源池中共包括候选频域单元组C i的个数为N Total-N data+1(即7个),即0<i≤6。该第二时间单元,即时间单元n+T中第二频域单元的集合包括4个第二频域单元,即频域单元3、频域单元4、频域单元5、频域单元6,则可以确定包括至少一个第二频域单元的候选频域单元组,即第二候选频域单元组为C2、C3、C4、C5、C6。
第一终端装置为了确定第二终端装置预约的资源对第一终端装置的影响,根据与第二候选频域单元组相关联的第一时间单元中的第一频域单元组来判断该第二候选频域单元 组是否可用,第一频域单元组为第一时间单元中包括至少一个第一频域单元的频域单元组,也就是说,第一频域单元组中包括至少一个第一频域单元,其中,第一频域单元组包括包括第一时间单元中的P个连续的频域单元,第二候选频域单元组包括第二时间单元中的连续的P个频域单元。
确定第一时间单元中与第二候选频域单元组相关联的第一频域单元组的方式包括但不限于以下一种或多种:
方式1,根据该第二候选频域单元组包括的第二频域单元的个数,确定与该第二候选频域单元组对应的第一频域单元组。
一种实施方式中,第一频域单元组包括的第一频域单元的个数与该第二候选频域单元组包括的第二频域单元的个数相同。例如图4所示的时间单元n+T(即,第二时间单元)中的第二候选频域单元组C2包括一个频域单元,频域单元3,则与该C2相关联的第一频域单元组可以是时间单元n(即第一时间单元)中包括一个第一频域单元的频域单元组,例如图5所示,在时间单元n中包括一个第一频域单元的频域单元组为R0和R3,则R0和R3可以与该第二候选频域单元组C2对应的,则第一终端装置可以根据R0和/或R3,确定C2是否可用于发送数据,例如,可以在R0或R3中随机选择一个作为确定C2是否可用的参考,也可以根据R0和R3结合采用测量参数的平均值作为确定C2是否可用的参考,还可以根据R0和R3中测量参数的值中较低或较高的一个作为确定C2是否可用的参考。再例如图5中,时间单元n+T中的第二候选频域单元组C3包括频域单元3、频域单元4两个第二频域单元,则与该C3相关联的第一频域单元组可以是时间单元n中包括两个第一频域单元的频域单元组,可以确定与该C3相关联的频域单元组为R1和R2,则第一终端装置根据R1和/或R2确定C3是否可用于发送数据。
本方案的其他实施方式中,第一频域单元组包括的第一频域单元的个数与该第二候选频域单元组包括的第二频域单元的个数还可以具有预定比例,但本申请不限于此。
方式2,根据第二候选频域单元组包括的第二频域单元的个数和第二候选频域单元组中第二频域单元的位置,确定与该第二候选频域单元组相关联的第一频域单元组。
第一频域单元组包括的第一频域单元的个数与该第二候选频域单元组包括的第二频域单元的个数相同,并且第一频域单元组中第一频域单元的位置与所述第二候选频域单元组中第二频域单元的位置相同。频域单元在频域单元组中的位置可以是频域单元在频域单元组的频域排列顺序,即,该频域顺序可以是频域单元在频域单元组中的索引,该索引可以为频率由低到高,或由高到低的顺序。
例如图5所示,时间单元n+T中的第二候选频域单元组C6包括一个第二频域单元,频域单元6,并且该频域单元6为C6中的第一个频域单元,那么时间单元n中与C6相关联的第一频域单元组为包括一个第一频域单元且该第一频域单元为频域单元组中的第一个频域单元,可以确定R3为与C6相关联的第一频域单元组,根据R3确定C6是否可以用于发送数据。
再例如,时间单元n+T中的第二候选频域单元组C3包括频域单元3、频域单元4两个第二频域单元,且仅包括两个第二频域单元,因此,时间单元n中包括两个第一频域单元且仅包括两个第一频域单元的频域单元组为与C3相关联的第一频域单元组,则可以确定与C3相关联的频域单元组为R1和R2,则第一终端装置可以根据R1和/或R2,确定 C3是否可用于发送数据。
方式3,根据第二候选频域单元组中包括的第二频域单元的个数X以及第二候选频域单元组在包括X个第二频域单元的多个频域单元组中的排列顺序,确定与该第二候选频域单元组对应的第一频域单元组。
一种实施方式中,该第一频域单元组中包括X个第一频域单元,且该第一频域单元组在包括X个第一频域单元的多个频域单元组中的排列顺序与第二候选频域单元组在包括X个第二频域单元的多个频域单元组中的排列顺序相同,该排列顺序可以是按频率依次增大的顺序,也可以是按频率依次减小的顺序,还可以是按索引值依次增大的顺序或按索引值依次减小的顺序,但本申请不限于此。例如,第一时间单元中包括X个第一频域单元的频域单元组为第三频域单元组,第二时间单元中包括X个第二频域单元的候选频域单元组为第四候选频域单元组,第二候选频域单元组为第四候选频域单元组中的一个候选频域单元组,则第三频域单元组中排列顺序与第二候选频域单元组在第四候选频域单元组中的排列顺序相同的频域单元组即为第一频域单元组。例如图5所示,第二候选频域单元组C4包括频域单元4、频域单元5两个第二频域单元,时间单元n+T中共包括C3、C4、C5共三个包括两个第二频域单元的频域单元组,其中C4为该C3、C4、C5三个频域单元组中的第二个频域单元组,因此,时间单元n中与该C4相关联的第一频域单元组为第一时间单元中包括两个第一频域单元的频域单元组,即R1、R2,其中R1、R2中的第二个频域单元组R2为C4相关联的第一频域单元组,第一终端装置根据R2确定C4是否可用。
再例如,图5中第二候选频域单元组C6中包括一个第二频域单元,频域单元6,时间单元n+T中共包括C2、C6两个包括一个第二频域单元的频域单元组,其中C6为该C2、C6两个第二候选频域单元组中的第二个频域单元组,因此,时间单元n中与该C6相关联的第一频域单元组包括一个第一频域单元,且第一时间单元中包括一个第一频域单元的第一频域单元组为R0和R3,其中R0和R3中的第二个第一频域单元组R3为与C6相关联的第一频域单元组,第一终端装置根据R3确定C6是否可用。
第一时间单元中共N个包括X个第一频域单元的第一频域单元组,即包括N个第三频域单元组,第二时间单元中共M个包括X个第二频域单元的第一频域单元组,即包括M个第四候选频域单元组。
可选地,当N<M的情况下,若第二候选频域单元组为第N+K个包括X个第二频域单元的频域单元组,则与该第二候选频域单元组相关联的频域单元组为第一时间单元中第N个包括X个第一频域单元组的频域单元组,即第一频域单元组为第一时间单元中第N个包括X个第一频域单元组的频域单元组,0<K≤M-N。
也就是说,当N<M的情况下,若第二候选频域单元组为M个第四候选频域单元组第N+K个频域单元组,则与该第二候选频域单元组相关联的频域单元组为N个第三频域单元组中的第N个频域单元组,0<K≤M-N。
例如图5中,时间单元n+T中共3个包括两个第二频域单元的第二候选频域单元组C3、C4、C5,时间单元n中共两个包括两个第一频域单元的第一频域单元组R1、R2,其中,第二候选频域单元组C5为C3、C4、C5中的第三个频域单元组,而时间单元n中没有第三个包括两个第一频域单元的频域单元组,则C5与R1、R2中的最后一个相关联,即与C5相关联的第一频域单元组为R2。
可选地,当N<M的情况下,若第二候选频域单元组为第N+K个包括X个第二频域单元的频域单元组的频域单元组,则将该第二频域单元作为可用于发送数据的候选频域单元组。
也就是说,当N<M的情况下,若第二候选频域单元组为M个第四候选频域单元组中的第N+K个频域单元组,则将该第二频域单元作为可用于发送数据的候选频域单元组。
例如图5中,时间单元n+T中共3个包括两个第二频域单元的第二候选频域单元组C3、C4、C5,时间单元n中共两个包括两个第一频域单元的第一频域单元组R1、R2,其中,第二候选频域单元组C5为C3、C4、C5中的第三个频域单元组,而时间单元n中没有第三个包括两个第一频域单元的第一频域单元组,则将C5作为可用于发送数据的候选频域单元组。
方式4,以上方式的结合,包括以下步骤:
a.根据第二候选频域单元组包括的第二频域单元的个数X,确定第一时间单元中包括X个第一频域单元的第一频域单元组,其中X为大于0的整数;
b.根据该第二候选频域单元组中第二频域单元的位置,在包括X个第一频域单元的一个或多个频域单元组中确定第一频域单元组,第一频域单元组中第一频域单元的位置与第二频域单元在该第二候选频域单元组中的位置相同;
c.第二候选频域单元组包括的频域单元均为第二频域单元,即X=P时,根据该第二候选频域单元组在包括X个第二频域单元的一个或多个第二候选频域单元组中的排列顺序,确定与该第二候选频域单元组对应的第一频域单元组,其中,第一时间单元中包括X个第一频域单元的频域单元组个数为N,即包括N个第三频域单元组,第二时间单元中包括X个第二频域单元的频域单元组的个数为M,即包括M个第四候选频域单元组,N、M为大于0的整数。
M≤N时,该第一频域单元组在包括X个第一频域单元中的多个频域单元组中的排列顺序与该第二候选频域单元组在包括X个第二频域单元的多个频域单元组中的排列顺序相同。也就是说,该第一频域单元组在M个第三频域单元组中的排列顺序与该第二候选频域单元组在N个第四候选频域单元组中的排列顺序相同。
M>N时,若第二候选频域单元组为包括X个第二频域单元的M个频域单元组中前N个中的一个,该第一频域单元组在包括X个第一频域单元中的多个频域单元组中的排列顺序与该第二候选频域单元组在包括X个第二频域单元的多个频域单元组中的排列顺序相同。若第二候选频域单元组为包括X个第二频域单元的M个频域单元组中的第M+K个频域单元组,则该第一频域单元组为包括X个第一频域单元中的多个频域单元组中的第N个频域单元组,0<K≤M-N。
也就是说,M>N时,若第二候选频域单元组为M个第四候选频域单元组中前N个中的一个,该第一频域单元组在N个第一频域单元组中的排列顺序与该第二候选频域单元组在M个第四候选频域单元组中的排列顺序相同。若第二候选频域单元组为M个第四候选频域单元组中的第M+K个频域单元组,则该第一频域单元组为N个第三频域单元组中的第N个频域单元组,0<K≤M-N。
例如图5所示的示例,根据步骤a可以确定与第二时间单元中包括1个第二频域单元的第二候选频域单元组C2、C6分别相关联的第一频域单元组在第一时间单元中包括1个 第一频域单元的两个频域单元组R0、R3中,以及,确定与第二时间单元中包括两个第二频域单元的第二候选频域单元组C3、C4、C5分别相关联的第一频域单元组在第一时间单元中包括两个第一频域单元的两个频域单元组R1、R2中。
根据步骤b可以确定第二频域单元在C2中的位置与第一频域单元在R0中的位置相同,因此C2与R0相关联,同理,C6与R3相关联,C3、C4、C5均包括两个第二频域单元与其分别相关联的第一频域单元组仍在R1、R2中。
根据步骤c可以确定C3在C3、C4、C5的排列顺序与R1在R1、R2中的排列顺序相同则C3相关联的第一频域单元组为R1,同理,C4与R2相关联。由于M>N,因此C3与R1、R2中的第N个(即,第二个),R2相关联,关联关系如图6所示。
第一终端装置根据第一频域单元组确定与其相关联的第二候选频域单元组是否可用于发送数据
再例如图7所示,时间单元n(第一时间单元)中包括5个第一频域单元(频域单元1、2、3、4、5),即5个第二终端装置用于发送数据的频域单元,时间单元n+T(第二时间单元)中包括4个第二频域单元(频域单元3、4、5、6),即4个第二终端装置预约的频域单元,第一终端装置待发送数据需要2个频域单元则包括8个频域单元的时间单元n+T中包括C0至C6,共8个候选频域单元组,其中,包括第二频域单元的候选频域单元组,即第二候选频域单元组为C2、C3、C4、C5。
根据步骤a可以确定与第二时间单元中包括1个第一频域单元的频域单元组C2、C6分别相关联的第一频域单元组在第一时间单元中包括1个第一频域单元的两个频域单元组R0、R5中,以及,确定与第二时间单元中包括2个第二频域单元的频域单元组C3、C4、C5分别相关联的第一频域单元组在第一时间单元中包括2个第一频域单元的4个频域单元组R1、R2、R3、R4中。
根据步骤b可以确定第二频域单元在C2中的位置与第一频域单元在R0中的位置相同,因此C2与R0相关联,同理,C6与R5相关联,C3、C4、C5均包括两个第二频域单元与其分别相关联的第一频域单元仍在R1、R2、R3、R4中。
根据步骤c可以确定C3在C3、C4、C5的排列顺序与R1在R1、R2、R3、R4中的排列顺序相同则C3相关联的第一频域单元为R1,同理,C4、C5分别与R2、R3相关联。
第一终端装置根据第一频域单元组确定与其相关联的第二候选频域单元组是否可用于发送数据
方式5,第一时间单元中包括T个第一频域单元组,第二时间单元中包括的S个第二候选频域单元组,第二时间单元中包括的前min(T,S)。个第二候选频域单元组与第一时间单元中包括的前min(N,M)个第一频域单元组依次一一对应,其中,min(T,S)表示取T和S中的最小值。
当T≥S时,每个第二候选频域单元与T个第一频域单元组中的前S个频域单元组一一对应;
当T<S时,S个第二候选频域单元组中的前T个候选频域单元组与T个第一频域单元组一一对应。可选地,S个第二候选频域单元组中的第T+1个第二候选频域单元至第S个第二候选频域单元组将作为可用于发送数据的候选频域单元组。
换个角度说,对于两个相关联的第一频域单元组(以下称为频域单元组#1)和第二候 选频域单元组(以下称为频域单元组#2),第一时间单元中包括第一频域单元的频域单元组也可以称为第五频域单元组,则第一时间单元中包括T个第五频域单元组,第二时间单元中包括第二频域单元的频域单元组也可以称为第六候选频域单元组,则第二时间单元中包括T个第六候选频域单元组,根据映射关系可以确定与候选频域单元组#2相关联的频域单元组#1,其中,映射关系为所述T个第五频域单元组中的前min(T,S)个第五频域单元组与所述S个第六候选频域单元组中的前min(T,S)个第六候选频域单元组依次一一对应,频域单元组#1属于第一时间单元上前min(T,S)个第五频域单元组中的一个第五频域单元组,候选频域单元#2组属于第二时间单元上前min(T,S)个第六候选频域单元组中的一个第六候选频域单元组,其中,min(T,S)表示取T和S中的最小值。
例如图5所示的示例,时间单元n中包括4个第一频域单元组R0、R1、R2、R3,时间单元n+T中包括5个第二候选频域单元组C2、C3、C4、C5、C6,因min(N,M)=4,时间单元n中的前4个第一频域单元组与时间单元n+T中的前4个第二候选频域单元组一一对应,因此,C2与R0相关联,C3与R1相关联,C4与R2相关联,C5与R3相关联,第一终端装置根据第一频域单元组确定与其相关联的第二候选频域单元组是否可用于发送数据,N、M为大于0的整数。可选地,没有相关联的第一频域单元组的第二候选频域单元组C6将作为可用于发送数据的候选频域单元组。
上面以一个时间单元(即第二时间单元)作为第一终端装置发送数据的候选时间单元为例进行说明,第一终端装置待发送数据的候选资源实际可以多个时间单元组成,可以是连续的多个时间单元,例如一个包括多个连续的时间单元的时间间隔窗,还可以是多个离散的时间间隔,多个时间单元中的每一个可以根据上述任一种方式确定是否可用。
例如,图8所示,第一时间间隔(也可以称为选择窗)包括多个第二时间单元,每个第二时间单元包括至少一个第一终端装置待发送数据的候选频域单元组,第一终端装置针对每个第二时间单元采用上述确定第二候选频域单元组相关联的第一频域单元组的一种或多种方式确定每个第二时间单元上的第二候选频域单元组相关联的第一频域单元组,进而根据第一频域单元组确定第二候选频域单元组是否可用。例如,一个第二终端装置通过第一信息指示在第一时间单元1中包括的第二终端装置用于发送数据的一个或多个频域单元,以及通过第二信息指示在第二时间单元2中包括的第二终端装置预约的一个或多个频域单元。另一个第二终端装置通过第一信息指示在第一时间单元2中包括的第二终端装置用于发送数据的一个或多个频域单元,以及通过第二信息指示在第二时间单元1中包括的第二终端装置预约的一个或多个频域单元。第一信息和第二信息可以承载在同一个控制信息中(如,侧行链路控制信息SCI、下行控制信息(downlink control information,DCI)或无线资源控制(radio resource control,RRC)信息中),也可以承载在不同的控制信息中。当第一信息和第二信息承载在不同的控制信息中时,第一时间单元与第二时间单元的关联关系可以通过第三信息指示,第三信息可以与第一信息或第二信息承载在同一个控制信息中。
根据第一频域单元组确定第二候选频域单元组是否用于发送数据,具体可以包括但不限于,根据第一终端装置检测得到的第一频域单元组的能量,确定第二候选频域单元组是否可用。当能量高于第一预设阈值的情况下,确定第二候选频域单元组不可以用于发送数据;当能量低于第一预设阈值的情况下,确定第二候选频域单元组可以用于发送数据。
作为示例非限定,该能量可以是参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal receiving quality,RSRQ)或接收信号的强度指示(received signal strength indicator,RSSI)是中的一种或多种。
作为示例非限定,第一预设阈值为系统预设或协议规定的。

第一终端装置对第一时间间隔中的每个第二时间单元采取相同方式排除第二候选频域单元组,排除后第一时间间隔中剩余的为第一终端装置可用的候选频域单元组。
根据第一时间间隔中被一个或多个第二终端装置预约的频域单元(即,第二频域单元),排除第一时间间隔中每个第二时间单元中所有包括第二频域单元的候选频域单元组(即,第二候选频域单元组),排除后第一时间间隔中剩余的为第一终端装置可用于发送数据的候选频域单元组。若第一时间间隔中可用的候选频域单元组占全部候选频域单元组的百分比小于第二预设门限值,第一终端装置从被排除的第二候选频域单元组中恢复部分候选频域单元组作为可用于发送数据的候选频域单元组,使得恢复后可用于发送数据的候选频域单元组占第一时间间隔中全部候选频域单元组的百分比大于第二预设门限值。
例如,第一时间间隔包括的Q个候选频域单元组,排除所有第二候选频域单元组后剩余A个候选频域单元组,当A/Q小于第二预设门限值时,第一终端装置取Q个候选频域单元组中被排除的Q-A个第二候选频域单元组中的Y个第二候选频域单元组,使得(A+Y)/Q大于或等于所述第二预设门限值,Y个第二候选频域单元组作为可用于发送数据的频域单元组。

排除不可用的第二候选频域单元组后,若第二时间间隔中剩余的可用于发送数据的候选频域单元组占全部候选频域单元组的百分比小于第二预设门限值,第一终端装置从被排除的第二候选频域单元组中恢复部分候选频域单元组作为可用于发送数据的候选频域单元组,使得恢复后的可用于发送数据的候选频域单元组占全部候选频域单元组的百分比大于第二预设门限值。
例如,第一时间间隔包括的Q个候选频域单元组,排除所有第二候选频域单元组后剩余A个候选频域单元组,当A/Q小于第二预设门限值时,第一终端装置取Q个候选频域单元组中被排除的Q-A个第二候选频域单元组中的Y个第二候选频域单元组,使得(A+Y)/Q大于或等于所述第二预设门限值,Y个第二候选频域单元组作为可用于发送数据的频域单元组。
