但对于终端设备而言,也带来了一些实现上以及具体使用中的问题,例如,宽带的终端射频以及极速的基带处理导致终端设备的功耗相比以往的无线通信系统增大。这会影响5G终端设备的待机时间以及使用时间甚至影响终端的电池寿命。
有鉴于此,本申请提出了一种灵活配置机制,网络设备可以向终端设备发送指示信令,通过该指示信令用于向终端设备灵活指示用于时域资源分配的目标配置信息,从而终端设备可以根据该目标配置信息,确定传输数据信道的时域资源,例如,在数据信道上的待传输业务的时延要求较低的情况,该目标配置信息所指示的用于传输数据信道的时域资源可以与调度该数据信道的控制信道的时域资源的时间间隔较大,从而终端设备可以降低控制信道的解调速度以及数据信道的编码速度,也就是说,终端设备可以以较低的芯片运转速度来接收数据或发送数据,从而降低终端设备的功耗。
图2为本申请实施例提供的一种无线通信的方法的示意性流程图,该方法200可以由终端设备执行,如图2所示,该方法200包括如下内容:
S210,终端设备接收第一信令,所述第一信令指示用于时域资源分配的多个配置信息中的目标配置信息;
S220,所述终端设备根据所述目标配置信息,确定传输数据信道所使用的时域资源。
可选地,在本申请实施例中,该用于时域资源分配的多个配置信息可以是预配置的,具体地,该多个配置信息可以是协议约定的,进一步地,可以将协议约定的该多个配置信息预设在该终端设备上。或者,该多个配置信息也可以是网络设备配置的,可选地,网络设备可以通过静态或半静态信令为终端设备配置该多个配置信息,例如,网络设备可以通过无线资源控制(Radio Resource Control,RRC)信令为终端设备配置该多个配置信息。或者,该多个配置信息中的部分配置信息可以是网络设备配置的,其他配置信息可以是预配置的,本申请实施例对此不作限定。
在本申请实施例中,终端设备可以接收网络设备发送的第一信令,该第一信令可以用于指示该多个配置信息中的目标配置信息,进一步地,终端设备可以根据该第一信令所指示的目标配置信息,确定传输数据信道所使用的时域资源,例如,传输数据信道所使用的时域资源相对于调度该数据信道的控制信道的时域资源的时间间隔,数据信道的调度方式,以及时域资源的起始位置和长度等信息。
可选地,在本申请实施例中,该第一信令可以为媒体接入控制(Media Access Control,MAC)控制元素(Control Element,CE)信令或物理下行控制信道(Physical Downlink  Control Channel,PDCCH)等动态信令。
具体地,可以在第一信令中携带指示信息,该指示信息用于指示网络设备配置的该目标配置信息,可选地,该指示信息可以为至少一个比特,具体地,该指示信息的长度可以根据该多个配置信息的数量确定,假设该多个配置信息为两个配置信息,此情况下,该指示信息可以为1个比特,或者,若该多个配置信息为三个配置信息,此情况下,该指示信息为2个比特,进一步地,可以设置该指示信息为不同的取值时,用于指示不同的配置信息。
可选地,在本申请实施例中,该数据信道可以是物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)等用于传输数据或业务的信道。
需要说明的是,该用于时域资源分配(TimeDomainResourceAllcation)的多个配置信息可以用于确定传输数据信道的时域资源,可选地,该多个配置信息中的每个配置信息包括如下参数中的至少一项:
数据信道的时域资源相对于调度该数据信道的控制信道的时间间隔,或称定时差,若该数据信道为PDSCH,则该定位差可以为PDCCH和PDSCH之间的定时差,即K0,或者若该数据信道为PUSCH,则该定位差可以为PDCCH和PUSCH之间的定时差,即K2;
数据信道的调度方式,或称数据信道的映射类型(mappingType),例如,基于时隙(slot based)的调度或基于非时隙(non-slot based)的调度;
数据信道的时域资源的起始时域位置和长度(startSymbolAndLength),可选地,该起始时域位置和长度可以用于指示数据信道的起始符号位置和连续占用的符号数目。
当然,本申请实施例的用于时域资源分配的配置信息也可以包括其他相关参数,本申请实施例对此不作具体限定。
应理解,PDCCH和PDSCH的定时差为PDCCH和PDSCH所在的时间单元的偏移量,以时间单元为时隙为例,则该PDCCH和PDSCH的定时差可以为该PDCCH和PDSCH所在的时隙的偏移量。若该定时差为零,即K0=0,则该PDSCH为同时隙调度,即调度数据的PDCCH和被调度的PDSCH处于同一时隙;或者若该定时差大于零,则该PDSCH为跨时隙调度,即调度数据的PDCCH和被调度的PDSCH处于不同时隙。对于定位差K2的含义亦是如此,这里不再赘述。
可以理解,同时隙调度通常需要终端设备提高PDCCH的解调速度以及PUSCH的编码速度,这就使得终端设备需要以较高的芯片时钟运转速度来接收数据或发送数据,导 致终端设备的功耗较大。对于跨时隙调度而言,终端设备可以降低PDCCH的解调速度以及PUSCH的编码速度,从而终端设备可以以较低的芯片时钟运转速度来接收数据或发送数据,有利于降低终端设备的功耗。
因此,在本申请实施例中,可以给终端设备配置多个配置信息,每个配置信息对应一组参数,假设该多个配置信息包括第一配置信息和第二配置信息,将该第一配置信息配置为支持同时隙调度,即最小的K0/K2等于0,将该第二配置信息配置为仅支持跨时隙调度,即最小的K0/K2大于0,换句话说,该第一配置信息可以适用于调度时延要求较高的业务,该第二配置信息可以适用于调度时延要求较低的业务,则在不同的场景下,网络设备可以通过第一信令向终端设备指示不同的配置信息。具体地,网络设备可以根据待调度业务的时延需求,确定为终端设备配置哪个配置信息,例如,在待调度业务的时延要求较低的情况下,该第一信令可以指示第二配置信息,从而终端设备可以降低PDCCH的解调速度以及PUSCH的编码速度,即终端设备可以以较低的芯片运转速度来接收数据或发送数据,从而能够降低终端设备的功耗。
应理解,在本申请实施例中,该多个配置信息还可以包括更多个配置信息,例如第三配置信息,每个配置信息可以对应一种应用场景,或者,时延需求,本申请实施例对此不作限定,以下,以该第一配置信息和第二配置信息为例进行说明。
可选地,在一些实施例中,该第一配置信息和第二配置信息可以是独立的配置信息(记为情况1),或者该第二配置信息可以是基于第一配置信息的配置信息(记为情况2),也就是说,需要根据第一配置信息确定第二配置信息所指示的用于数据信道的时域资源分配的配置信息。
例如,该第二配置信息可以是相对于该第一配置信息的偏移信息,从而终端设备可以根据该第一配置信息和该偏移信息,确定该第二配置信息对应的用于时域资源分配的配置信息。
以下,结合表1至表4所示的具体表格,以PDSCH的时域资源分配为例进行说明。需要说明的是,上述表1至表4所示的参数仅仅为说明问题的示例,不构成对参数的个数、类型以及取值的任何限定。
对于情况1而言,该第一配置信息和第二配置信息可以分别对应表1和表2中所示的配置信息,从表1和表2可看出,表1中的定时差(即K0)相对于表2中的定时差较小,也就是说,表1更适合传输时延要求较高的业务,表2更适合传输时延要求较低的业务。因此,在待调度业务的时延要求不高的情况下,网络设备可以给终端设备配置该2中的配置信息,有利于降低终端设备的功耗;或者,在待调度业务的时延要求较高的情 况下,网络设备可以给终端设备配置该表1中的配置信息,例如,表1中的配置1或配置2,从而能够保证待调度业务的及时传输。
表1
  K0 mappingType startSymbolAndLength
配置1 0 typeA 0
配置2 0 typeA 1
配置3 4 typeB 0
配置4 4 typeB 1
表2
  K0 mappingType startSymbolAndLength
配置1 2 typeA 0
配置2 2 typeA 1
配置3 4 typeB 0
配置4 4 typeB 1
应理解,该第一配置信息和第二配置信息可以对应独立的表格,或者也可以为也可以将第一配置信息和第二配置信息对应的表格合并为一个表格,例如,可以将表2中的配置1~配置4合并到表1,修改索引值为配置5~配置8,然后网络设备可以通过配置1~配置8的索引值向终端设备指示所配置的配置信息,对于本示例来说,可以采用3比特来指示该配置1~配置8,通过该3比特取不同的取值来指示该配置1~配置8。
可选地,在本申请实施例中,也可以将该多个配置信息合并在一起,通过不同的索引值指示合并后的每个配置信息中的具体配置项,以上,该多个配置信息的存储格式仅为示例,本申请实施例并不限定该多个配置信息的具体存储格式。
对于情况2而言,该第一配置信息可以对应表3中所示的配置信息,第二配置信息可以为偏移信息,可选地,该偏移信息可以为单个偏移量,该单个偏移量可以应用于该表3中的每个配置项或部分配置项,例如,该单个偏移量可以适用于表3中的配置1~配置4,或者只适用于表3中的配置1和配置2;或者该偏移信息可以是一组偏移量,分别对应于该表3中的一个配置项,具体对应方式不作具体限定。
可选地,以该第二配置信息指示单个偏移量(K0_offset)为例,假设该K0_offset=2,该单个偏移量适用于表3中的每个配置项,则根据第一配置信息和该偏移量,可以确定第二配置信息对应的用于时域资源分配的配置信息,如表4所示。
表3
  K0 mappingType startSymbolAndLength
配置1 0 typeA 0
配置2 0 typeA 1
配置3 2 typeB 0
配置4 2 typeB 1
表4
  K0 mappingType startSymbolAndLength
配置1 2 typeA 0
配置2 2 typeA 1
配置3 4 typeB 0
配置4 4 typeB 1
在具体实现中,在待调度业务的时延要求不高的情况下,网络设备可以给终端设备配置第二配置信息,进一步地,该终端设备可以根据该第一配置信息和该第二配置信息指示的偏移信息,得到该表4中的配置信息,进一步可以根据表4中的配置信息确定传输PDSCH的时域资源;在待调度业务的时延要求较高的情况下,网络设备可以给终端设备配置该表3中的配置信息,例如,表1中的配置1或配置2,从而能够保证PDSCH的及时传输。
因此,在本申请实施例中,网络设备可以根据待调度的业务的时延需求,通过第一信令为终端设备灵活配置PUSCH或PDSCH的时域资源,例如,在待调度业务的时延要求较高时,为终端设备配置定时差较小的时域资源,从而实现待调度业务的及时调度,或者在待调度业务的时延要求较低时,为终端设备配置定时差即K0/K2较大的时域资源,从而终端设备可以以较低的芯片运转速度来接收数据或发送数据,有利于降低终端设备的功耗。
