图2是根据本申请实施例的通信方法200的示意性流程图,所述方法200可以由图1所述的无线通信系统中的终端设备执行,如图2所示,所述方法200包括:
S210,终端设备确定用于监听下行控制信息的目标监听资源;
S220,在所述目标监听资源上,监听下行控制信息。
在本申请实施例中,所述目标监听资源包括周期性的时域资源,为了便于描述,将所述周期性的时域资源的周期记为监听周期,每个监听周期内包括用于监听所述下行控制信息的监听位置,即,所述目标监听资源包括周期性的监听位置。可选地,每个监听周期内的每个监听位置还可以对应特定的频域宽度,或者也可以对应整个系统带宽,也就是说,所述目标监听资源既可以包括周期性的时域资源还可以包括一定的频域资源。
应理解,在本申请实施例中,所述目标监听资源包括的时域资源可以为子帧粒度的,或者也可以为符号粒度的,本申请实施例对于所述目标监听资源的时间粒度此不作限定。
以下,主要针对所述目标监听资源包括的周期性时域资源进行介绍。作为示例而非限定,如图3所示,所述监听周期为4毫秒(ms),每个监听周期内的可以包括能够用于监听所述下行控制信息的监听位置,例如,第1个和第3个子帧,可选的,所述每个监听周期内还可以包括不能用于监听所述下行控制信息的位置,例如,第2个子帧和第4个子帧,那么这些周期性的子帧集合就构成所述目标监听资源,即所述目标监听资源可以包括{#n ,#n+2, #n+4, #n+6, #n+8, #n+10, #n+12, #n+14, #n+16, #n+18,…}。那么所述终端设备可以在每个监听周期的第1个子帧和第3个子帧上监听所述下行控制信息,在第2个子帧和第4个子帧上不监听所述下行控制信息。再如,所述每个监听周期内的监听位置可以为稀疏性的监听位置,例如,在每个监听周期内的前一个或多个子帧进行监听,其他子帧不监听,或者在所述每个监听周期内的中间一个或多个子帧进行监听,其他子帧不监听,或者也可以在所述每个监听周期内的最后一个或多个子帧进行监听,其他子帧不监听,如图4所示,每个监听周期(4ms)内的第2个和第3个子帧用于监听下行控制信息,第1和第4个子帧不能用于监听下行控制信息,那么这些周期性的子帧集合就构成所述目标监听资源,即所述目标监听资源可以包括{#n+1 ,#n+2, #n+5, #n+6, #n+9, #n+10, #n+13, #n+14, #n+17, #n+18,…}。
应理解,本申请实施例不限定每个监听周期内包括的监听位置的数量,可以为一个或多个,以及监听位置在每个监听周期内的位置,例如,监听位置可以位于每个监听周期的前部,中部或尾部,例如,监听周期为4ms,每个周期内的监听位置可以包括四个子帧中的一个或多个子帧,若包括一个子帧,所述一个子帧可以为四个子帧中的任一个子帧,或者若包括至少两个子帧,所述至少两个子帧可以是连续的子帧,也可以是不连续的,例如,包括第2个子帧和第3个子帧,或者也可以包括第1个子帧和第3个子帧,或者也可以包括第3个子帧和第4个子帧。
还应理解,每个监听周期内的监听位置可以是完整子帧,也可以是部分子帧,其中,完整子帧指示终端设备可以占用子帧包含的全部(7个或14个)符号监听下行控制信息,部分子帧指示所述终端设备只能占用该子帧包含的一部分符号监听下行控制信息,而在子帧的另一部分符号不监听所述下行控制信息,例如,部分子帧包括一个子帧的前2个符号,也就是所述终端设备在子帧的前2个符号监听下行控制信息,而在子帧的其他符号上不监听下行控制信息,或者也可以包括一个子帧的后3个符号,即所述终端设备在子帧的后3个符号监听下行控制信息,在子帧的其他符号上不监听下行控制信息,或者也可以包括一个子帧的中间2个符号,即所述终端设备在子帧的中间2个符号监听下行控制信息,在子帧的其他符号上不监听下行控制信息。
需要说明的是,在每个监听周期内可以只包括能够用于监听所述下行控制信息的监听位置,那么在每个监听周期内,所述终端设备可以在所述能够用于监听所述下行控制信息的监听位置上监听所述下行控制信息,而在每个监听周期内的其他时域资源上不监听所述下行控制信息。可选的,所述每个监听周期内还可以包括不能用于监听所述下行控制信息的位置,例如,网络设备调度所述终端设备在一个或多个时隙传输数据时,所述不能用于监听所述下行控制信息的位置可以包括用于所述终端设备进行数据传输的位置,可选的,所述每个监听周期内不能用于监听所述下行控制信息的位置还可以包括所述网络设备用于传输下行同步信号或下行参考信号的位置,也就是说,所述目标监听资源可以不包括用于所述终端设备进行数据传输的时域资源,也可以不包括用于所述网络设备传输下行同步信号和下行参考信号的时域资源,即所述终端设备不在用于数据传输的时域资源上监听下行控制信息,也不再网络设备传输下行同步信号和下行参考信号的时域资源上监听下行控制信息,从而能够节省耗电开销。
可选的,在一些实施例中,终端设备可以确定用于监听下行控制信息的目标监听资源,因此,增加了监听下行控制信息的灵活性。可选地,网络设备可以给所述终端设备预配置一组监听资源,所述一组监听资源可以包括至少一个监听资源,所述至少一个监听资源中的每个监听资源都包括周期性的时域资源,每个监听周期内都可以包括能够用于监听所述下行控制信息的监听位置,每个监听资源对应的监听周期或监听位置等信息不同。可选地,若所述网络设备预配置的所述至少一个监听资源包括多个监听资源,所述终端设备可以在所述多个监听资源中选择用于监听所述下行控制信息的目标监听资源,即所述目标监听资源为所述多个监听资源中的一个监听资源。可选的,所述终端设备也可以对所述多个监听资源中的第一监听资源进行调整,例如,调整第一监听资源的监听周期或每个监听周期内的监听位置的数量,将调整后的所述第一监听资源作为所述目标监听资源。
可选地,若所述网络设备预配置的所述至少一个监听资源只包括一个监听资源,也就是说,所述网络设备为所述终端设备只配置了一个监听资源,如果终端设备根据所述一个监听资源进行下行控制信息监听,灵活性较差,因此所述终端设备可以根据对下行控制信息的监听机会的需求,调整所述一个监听资源,例如,调整监听周期或每个监听周期内的监听位置,将调整后的所述一个监听资源作为所述目标监听资源,例如,若所述终端设备确定需要增加监听机会,那么所述终端设备可以减小监听周期,或增加每个监听周期内的监听位置的数量,或者若所述终端设备确定需要减少监听机会,那么所述终端设备可以增大监听周期,或减少每个监听周期内的监听位置的数量。
因此,本申请实施例的通信方法,终端设备可以自己确定用于监听下行控制信息的目标监听资源,因此,增加了监听下行控制资源的灵活性,可选地,所述终端设备可以根据对下行控制信息的监听机会的需求,在预配置的多个监听资源中确定目标监听资源,或者也可以根据对下行监听资源的需求对预配置的监听资源进行调整,将调整后的监听资源作为目标监听资源,从而增加了终端监听下行控制信息的灵活性。
可选的,所述终端设备可以结合下行控制信息的历史接收情况,在所述至少一个监听资源或一组监听资源中确定所述目标监听资源,例如,若所述终端设备在至少一个监听周期内未监听到所述下行控制信息,也就是说,用于上行调度或下行分配的下行控制信息的数量不多,因此,每个监听周期内的监听位置不必太多,或监听不必太频繁,或者说,单位时间内的监听位置不必太密集,因此,所述终端设备可以在所述一组监听资源或至少一个监听资源中选择监听位置相对稀疏的监听资源作为所述目标监听资源,从而能够节约所述终端设备的功耗。
可选的,所述终端设备可以结合下行控制信息的历史接收情况,在至少一个监听资源或一组监听资源中确定所述目标监听时域,例如,若所述终端设备在至少一个监听周期内监听到所述下行控制信息,也就是说,用于上行调度或下行分配的下行控制信息的数量较多,因此,每个监听周期内的监听位置需求较多,或者说,单位时间内的监听位置需求较多,因此,所述终端设备可以在至少一个监听资源或一组监听资源中选择监听位置相对密集的监听资源作为所述目标监听资源,从而能够增加监听机会,从而能够减小下行控制信息的接收时延。
可选的,在一些实施例中,所述方法还包括:
所述终端设备接收网络设备发送的一组监听资源的信息;
所述终端设备确定用于监听下行控制信息的目标监听资源,包括:
根据所述一组监听资源,确定所述目标监听资源。
具体的,所述网络设备可以向所述终端设备发送一组监听资源的信息,可选的,所述网络设备可以通过高层信令给所述终端设备配置所述一组监听资源的信息,从而所述终端设备可以根据所述一组监听资源,确定目标监听资源,可选地,所述终端设备可以直接在所述一组监听资源中确定所述目标监听资源,也可以对所述一组监听资源中的第一监听资源进行调整,例如,调整监听周期或监听位置,将调整后的所述第一监听资源作为所述目标监听资源。
可选的,在一些实施例中,所述根据所述一组监听资源,确定所述目标监听资源,包括:
根据所述一组监听资源,以及所述下行控制信息的接收情况,确定所述目标监听资源。
具体的,所述终端设备可以根据当前时刻之前的一段时间内所述下行控制信息的接收情况,在所述一组监听资源中确定所述目标监听资源,即所述目标监听资源为所述一组监听资源中的一个监听资源。或者,所述终端设备可以根据下行控制信息的接收情况,调整所述一组监听资源中的第一监听资源,然后将调整后的所述第一监听资源确定为所述目标监听资源,可选地,所述终端设备也可以将所述一组监听资源都做调整,例如采用同样的比例,进行监听周期的缩放,每个监听周期内的监听位置之间的间隔作同等比例的缩放。例如,若一段时间内,例如一个或多个监听周期内,未接收到所述下行控制信息,所述终端设备确定需要减少监听次数,那么所述终端设备可以在所述一组监听资源中选择相对于所述终端设备当前使用的监听资源而言,监听次数更稀疏的监听资源作为所述目标监听资源,可选地,若所述终端设备当前使用第二监听资源监听下行控制信息,那么所述终端设备可以调整所述第二监听资源的监听参数,例如,增大监听周期或减少每个监听周期内的监听位置的数量,从而减少单位时间内的监听次数。再如若一段时间内,例如一个或多个监听周期内,接收到一个或多个下行控制信息,所述终端设备确定需要增加监听次数,那么所述终端设备可以在所述一组监听资源中选择相对于所述终端设备当前使用的监听资源而言,监听次数更密集的监听资源作为所述目标监听资源,可选地,若所述终端设备当前使用第二监听资源监听下行控制信息,那么所述终端设备可以调整所述第二监听资源的监听参数,例如,减小监听周期或增大每个监听周期内的监听位置的数量,从而增加单位时间内的监听次数。
可选的,在一些实施例中,所述根据所述一组监听资源,以及所述下行控制信息的接收情况,确定所述目标监听资源,包括:
若在第一监听资源包括的至少一个监听周期内监听到所述下行控制信息,在所述一组监听资源中确定第二监听资源,所述第一监听资源为所述终端设备当前用于监听所述下行控制信息的监听资源;

所述在所述目标监听资源上,监听下行控制信息,包括:
在所述第二监听资源上,监听所述下行控制信息。
其中,单位时间内所述第二监听资源比所述第一监听资源包括的监听位置的数量多。
具体的,终端设备当前使用第一监听资源监听所述下行控制信息,但是在所述第一监听资源包括的一个或多个监听周期内都监听下行控制信息,可以理解为所述下行控制信息的数量较多,此情况下,需要增多监听机会,以减小下行控制信息的接收时延,因此,所述终端设备可以在所述一组监听资源中确定第二监听资源,所述第二监听资源比所述第一监听资源的资源丰富,或者说,单位时间内的监听位置更多,例如,若所述第一监听资源以4ms为监听周期,每个监听周期内包括两个监听位置,那么可以确定以4ms为监听周期,每个监听周期内包括三个监听位置的监听资源为所述目标监听资源,或可以确定以3ms为监听周期,每个周期内包括2个监听位置的监听资源为所述目标监听资源,也就是说,可以在所述一组监听资源中确定单位时间内监听位置的数量更多的监听资源作为所述目标监听资源。可选的,所述终端设备还可以调整所述第一监听资源的监听周期或每个监听周期内的监听位置,将调整后的所述第一监听资源确定为所述目标监听资源,例如,减小监听周期或增多每个监听周期内的监听位置,从而使得调整后的所述第一监听资源单位时间内的监听数量增多。
可选的,在一些实施例中,所述根据所述一组监听资源,以及所述下行控制信息的接收情况,确定所述目标监听资源,包括:
若在第三监听资源包括的至少一个监听周期内未监听到所述下行控制信息,所述终端设备在所述一组监听资源中确定第四监听资源;
将所述第四监听资源确定为所述目标监听资源;
所述在所述目标监听资源上,监听下行控制信息,包括:
在所述第四监听资源上,监听所述下行控制信息。
单位时间内所述第四监听资源比所述第三监听资源包括的监听位置的数量少。
具体的,若终端设备当前使用第三监听资源监听所述下行控制信息,但是在所述第三监听资源包括的至少一个监听周期内都未监听都下行控制信息,可以理解为所述下行控制信息的数量较少,此情况下,需要减少监听次数,以降低增大终端的功耗,因此,所述终端设备可以在所述一组监听资源中确定第四监听资源,所述第四监听资源比所述第三监听资源的资源少,或者说,单位时间内的监听位置较少,例如,所述第三监听资源以4ms为监听周期,每个监听周期内包括两个监听位置,那么可以确定以4ms为监听周期,每个监听周期内包括一个监听位置的监听资源为所述目标监听资源,或可以确定以3ms为监听周期,每个周期内包括1个监听位置的监听资源为所述目标监听资源。也就是说,可以在所述一组监听资源中确定单位时间内监听位置的数量更少的监听资源作为所述目标监听资源。可选的,所述终端设备还可以调整所述第三监听资源的监听周期或每个监听周期内的监听位置,将调整后的所述第三监听资源确定为所述目标监听资源,例如,增大监听周期或减少每个监听周期内的监听位置,从而使得调整后的所述第三监听资源单位时间内的监听数量减少。
因此,本申请实施例的通信方法,可以在下行控制信息的数量较多时,增加单位时间内的监听位置的数量,从而减小下行控制信息的接收时延,在下行控制信息的数量较少时,减小单位时间内的监听位置的数量,从而降低终端的功耗,因此,能够根据对下行控制信息的监听机会的需求,灵活调整用于监听下行控制信息的监听资源,从而能够实现终端功耗和下行控制信息的接收时延的折中。
可选地,在一些实施例中,所述根据所述一组监听资源,确定所述目标监听资源,包括:
根据所述一组监听资源,以及所述终端设备当前配置的基础参数集,确定所述目标监听资源。
具体的,所述一组监听资源可以对应一个基础参数集,所述一组监听资源对应的基础参数集可以理解为参考基础参数集,所述终端设备可以根据所述终端设备当前配置的第一基础参数集与所述参考基础参数集,确定所述目标监听资源,例如,若所述第一基础参数集与所述参考基础参数集相同,那么所述终端设备可以在所述一组监听资源中确定所述目标监听资源,从一组监听资源中确定目标监听资源的方法可以参考前述实施例,这里不再赘述。或者,若所述第一基础参数集与所述参考基础参数集不同,所述终端设备可以将所述一组监听资源调整,得到另一组监听资源,然后从所述另一组监听资源中确定所述目标监听资源,从另一组监听资源中确定目标监听资源的方法可以参考前述实施例中从一组监听资源中确定所述目标监听资源的相关描述,这里不再赘述。或者若所述第一基础参数集与所述参考基础参数集不同,所述网络设备还可以给所述终端设备配置另一组监听资源,所述另一组监听资源对应所述第一基础参数集,也就是说网络设备可以针对不同的基础参数,配置不同的监听资源。
可选的,在一些实施例中,所述一组监听资源对应第一基础参数集,所述根据所述一组监听资源,以及所述终端设备当前配置的基础参数集,确定所述目标监听资源,包括:
若所述终端设备当前配置的第二基础参数集与所述第一基础参数集相同, 从所述一组监听资源中确定所述目标监听资源;或
若所述终端设备当前配置的所述第二基础参数集与所述第一基础参数集不同,根据所述一组监听资源,确定另一组监听资源;
从所述另一组监听资源中确定所述目标监听资源。
具体的,所述一组监听资源可以对应第一基础参数集,若所述终端设备当前配置基础参数集为第二基础参数集,若所述第二基础参数集和所述第一基础参数集相同,可以从所述一组监听资源中确定所述目标监听资源,所述一组监听资源中确定所述目标监听资源的方法参考前述实施例,这里不再赘述。若所述第二基础参数集与所述第一基础参数集不同,那么所述终端设备可以将所述第一基础参数集作为参考基础参数集,根据所述一组监听资源,确定另一组监听资源,然后从所述另一组监听资源中确定所述目标监听资源。
可选的,在一些实施例中,所述根据所述一组监听资源,确定另一组监听资源,包括:
根据所述一组监听资源,以及所述第二基础参数集对应的子载波间隔和所述第一基础参数集对应的子载波间隔的比例关系,确定所述另一组监听资源。
具体的,在NR系统中,物理层可以支持多个基础参数集,不同的基础参数集可以用不同的子载波间隔区分,可以将某个子载波间隔对于的基础参数集作为参考基础参数集,例如,可以将15kHz的子载波间隔对应的基础参数集作为参考基础参数集,时域上在1ms子帧上有两个时隙(slot),每个slot包括的OFDM符号为7个或14个,其他的基础参数集的子载波间隔取值为15kHz*2n,每个子帧包括的时隙数为参考基础参数集对应的一个子帧包括的时隙数*2n。因此,所述终端设备可以根据基础参数集的缩放方式进行监听资源的缩放,其他基础参数集对应的监听资源也可以通过2n进行缩放。
可选的,在一些实施例中,所述根据所述一组监听资源,以及所述第二基础参数集对应的子载波间隔和所述第一基础参数集对应的子载波间隔的比例关系,确定所述另一组监听资源,包括:
将所述一组监听资源中的第五监听资源的监听周期乘以A/B,并将所述第五监听资源中的每个监听周期中的监听位置之间的间隔乘以A/B;
将调整后的所述第五监听资源确定为所述另一组监听资源中的第六监听资源。
其中,所述A为所述第一基础参数集的子载波间隔,所述B为所述第二基础参数集的子载波间隔。
如图5所示,15KHz的基础参数集为参考基础参数集,对应的第一监听资源的监听周期为4ms,每个监听周期内包括第1个子帧和第3个子帧的监听位置,那么对于30KHz的基础参数集对应的第二监听资源,可以通过2n进行缩放,由于30KHz相对于15KHz是进行21缩放的,所以所述第二监听资源可以相对于所述第一监听资源进行21缩放。那么所述第二监听资源的监听周期为2ms,每个监听周期内的监听位置相对不变,监听位置之间的间隔按照缩放比例进行缩放,即两个监听位置之间的间隔由2ms变为1ms,因此,单位时间内的监听位置的数量增多,因此30KHz的基础参数集相对于15KHz的基础参数集对应的监听资源较多,因此,监听机会较多,接收下行控制信息的时延较低,对终端设备的功耗也较大,因此,所述终端设备确定了跟当前配置的基础参数集对应的监听资源后,还可以结合下行控制信息的接收情况,确定目标监听资源,具体方法可以参考前述实施例,为了简洁,这里不再赘述。

可选地,所述目标监听资源不包括用于所述终端设备传输数据的时域位置。
具体的,若所述网络设备调度所述终端设备在一个或多个时隙上进行数据传输,那么所述目标监听资源可以不包括用于所述终端设备传输数据的时域位置,从而所述终端设备可以不在所述用于数据传输的位置进行下行控制信息的监听,从而能够降低终端的功耗。
可选地,所述目标监听资源不包括用于网络设备传输下行同步信号或下行参考信号的时域位置。
具体的,若所述网络设备可以在一些时域位置传输下行同步信号或下行参考信号,因此,这些时域位置可以不用进行下行控制信息的监听,那么所述目标监听资源可以不包括用于所述网络设备传输下行同步信号和下行参考信号的时域位置,从而所述终端设备可以不在所述用于传输下行同步信号和下行参考信号的位置进行下行控制信息的监听,从而能够降低终端的功耗。
