背景技术
在通信系统中,通常一个控制信息(control information,CI)调度一个传输块(transport block,TB)。数据信道可以是物理下行数据信道或物理上行数据信道。
为了降低CI传输的开销,节省传输资源,可以使用一个CI调度多个数据信道,或者使用一个CI调度多个传输块。
当一个CI调度多个传输块时,该CI需要指示调度的传输块的数目,该CI还需要指示每个传输块对应的混合自动重发请求(hybrid automatic retransmission request,HARQ)进程(process)索引(number)。
在现有技术中,一个CI调度多个传输块时,该CI除了需要指示调度的传输块的数目之外,还需要针对每个传输块对应的HARQ进程索引进行单独指示,因此需要的指示开销很大。
上述现有技术中CI调度传输块的比特开销过大,特别考虑到高可靠性的控制信道性能,太多的比特开销需要消耗更多的传输资源,如何降低CI调度传输块的指示开销仍有待解决。
发明内容

在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述控制信息用于多个传输块的调度,所述多个传输块中的除第一个传输块以外的其它传输块的HARQ进程索引根据所述第一个传输块的HARQ进程索引确定;和/或,所述多个传输块中的每个传输块对应一个HARQ进程索引,且所述多个传输块对应的多个HARQ进程索引是连续的。
其中,若控制信息调度多个传输块时,第一信息用于指示第一个传输块的HARQ进程索引,对于多个传输块中的除第一个传输块以外的其它传输块的HARQ进程索引根据第一个传输块的HARQ进程索引确定。例如其它传输块的HARQ进程索引可以使用预设的计算方式对第一个传输块的HARQ进程索引进行计算,从而得到其它传输块的HARQ进程索引。例如预设的计算方式可以包括多种计算规则,后续实施例中详细说明。对于多个传输块中的每个传输块对应一个HARQ进程索引,即每个传输块都配置有一个HARQ进程索引,而且多个传输块对应的多个HARQ进程索引是连续的,当第一信息用于指示第一个传输块的HARQ进程索引时,其它传输块的HARQ进程索引可以根据所有HARQ进程索引是连续的得到。举例说明,第一个传输块的HARQ进程索引是1,若控制信息共调度3个传输块,则其它传输块的HARQ进程索引从HARQ进程索引1开始,采用连续规则确定出其它3个传输块的HARQ进程索引是2,3,4。

在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述高层信令为无线资源控制信令,所述无线资源控制信令包括第一信息;所述第一信息中包括所述传输块信息,且所述传输块信息只指示所述控制信息调度的传输块中的第一个传输块的HARQ进程索引时,所述控制信息指示所述控制信息调度的传输块个数;或者,所述第一信息中包括所述最大传输块个数信息和/或所述第一组合信息时,所述控制信息指示所述控制信息调度的传输块个数和指示所述控制信息调度的传输块中的第一个传输块的HARQ进程索引,或者所述控制信息指示所述控制信息调度的所有传输块的HARQ进程索引。
其中,第一信息包括传输块信息,若该传输块信息只指示控制信息调度的传输块中的第一个传输块的HARQ进程索引时,控制信息指示控制信息调度的传输块个数。因此通过传输块信息和控制信息可以确定出第一个传输块的HARQ进程索引和控制信息调度的传输 块个数。在另一种实现场景下,第一信息为高层信令,第一信息中包括最大传输块个数信息和/或第一组合信息时,控制信息可以指示控制信息调度的传输块个数和指示控制信息调度的传输块中的第一个传输块的HARQ进程索引,或者控制信息指示控制信息调度的所有传输块的HARQ进程索引。对于控制信息指示第一个传输块的HARQ进程索引,还是所有个传输块的HARQ进程索引,具体取决于应用场景,此处不做限定。
在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述第一信息包括所述传输块信息时,所述方法还包括:所述第一通信设备接收所述第二通信设备发送的HARQ进程索引集合信息,所述HARQ进程索引集合信息指示至少一个HARQ进程索引集合。其中,第二通信设备还可以向第一通信设备发送HARQ进程索引集合信息,从而第一通信设备可以根据该HARQ进程索引集合信息确定出至少一个HARQ进程索引集合。第二通信设备可以向第一通信设备发送HARQ进程索引集合信息,从而第二通信设备进一步的向第一通信设备发送控制信息,该控制信息在第二通信设备所确定的HARQ进程索引集合中进行HARQ索引的指示和/或传输块个数的指示,因此可以减少控制信息的指示开销。
在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述最大传输块个数取值为取值集合{2,4}或取值集合{1,2,4}中的值。本申请实施例中第二通信设备可以限定控制信息调度的最大传输块个数,从而使得控制信息只需要从取值集合{2,4}或取值集合{1,2,4}中指示具体的最大传输块个数,而不需要对所有的传输块个数进行指示,因此可以减少控制信息的指示开销。
在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述控制信息调度的所有传输块是全部初传的传输块,或者所述控制信息调度的所有传输块是全部重传的传输块。其中,全部初传的传输块指的是控制信息调度的所有传输块的传输方式都是初传,全部重传的传输块指的是控制信息调度的所有传输块的传输方式都是重传。例如控制信息中可以使用1个比特指示所有传输块是全部初传的传输块或者全部重传的传输块,从而使得通信设备通过解析该控制信息确定所有传输块采用全部初传还是全部重传。
在第一方面或者第二方面或者第三方面或者第四方面的一种可能设计中,所述第一通信设备工作在覆盖增强模式B,或覆盖增强等级2,或覆盖增强等级3。
在本申请的第三方面中,第一通信设备的组成模块还可以执行前述第一方面以及各种可能的实现方式中所描述的步骤,详见前述对第一方面以及各种可能的实现方式中的说明。

为解决现有技术中控制信息调度传输块的指示开销过大问题,本申请实施例提出如下的数据传输方法,适用于控制信息调度传输块场景中,本申请实施例中控制信息具体可以是下行控制信息。请参阅图2所示,为本申请实施例提供的网络设备和终端设备之间的一种交互流程示意图,本申请实施例提供的数据传输方法,主要包括如下步骤:
201、第二通信设备确定控制信息调度的传输块个数,以及确定控制信息调度的传输块中每个传输块对应的HARQ进程索引。
在本申请实施例中,控制信息由第二通信设备生成,第二通信设备通过控制信息向第一通信设备下发控制指令,后续举例中该控制信息用CI表示。第二通信设备首先确定用于数据传输的传输块(transport block,TB)个数(number)。例如,第二通信设备确定的传输块个数可以是1个或者2个或者3个或者4个。第二通信设备还需要确定控制信息调度的传输块中每个传输块对应的HARQ进程(process)索引,其中,HARQ进程索引是指传输块对应的HARQ进程索引,HARQ进程索引也可以称为HARQ进程序列号。
举例说明如下,如图3所示,控制信息可以调度4个传输块,分别为TB1、TB2、TB3、TB4,其中第二通信设备还可以确定每个传输块对应的HARQ进程索引。
在本申请的一些实施例中,第一通信设备可以工作在覆盖增强模式B,或覆盖增强等 级2,或覆盖增强等级3。当第一通信设备工作在覆盖增强模式B时,控制信息调度的最大传输块个数可以是4个。不限定的是,第一通信设备也可以工作在其他模式,例如可以工作在覆盖增强模式A,或覆盖增强等级0,或覆盖增强等级1。
202、第二通信设备生成第一信息,并向第一通信设备发送第一信息;
其中,第一信息用于指示传输块集合信息、最大传输块个数信息、传输块信息、第一组合集合信息中的一种或多种;传输块集合信息指示传输块个数范围和/或指示传输块个数集合。
在本申请的一些实施例中,为了使第一通信设备能够获取到该第二通信设备确定的传输块个数和每个传输块对应的HARQ进程索引,第二通信设备可以生成一个第一信息,将该第一信息发送给第一通信设备,从而使得第一通信设备能够根据接收到的第一信息来获取到该第二通信设备确定的传输块个数和每个传输块对应的HARQ进程索引。为了节省控制信息的指示开销,本申请实施例中第二通信设备所生成的第一信息可以用于指示如下信息中的一种或者多种:传输块集合信息、最大传输块个数信息、传输块信息、第一组合集合信息。举例说明如下,第一信息可以只用于指示传输块集合信息,第一信息可以只用于指示最大传输块个数信息,第一信息可以只用于指示传输块信息,第一信息可以只用于指示第一组合集合信息。不限定的是,第一信息可以指示上述四种信息中的任意两种信息,或者任意三种信息,或者同时指示上述四种信息。

接下来对本申请实施例中第二通信设备生成的第一信息具体举例说明。
在本申请的一些实施例中,第一信息包含第一字段;
第一字段的比特状态属于第一状态时,指示控制信息用于一个传输块的调度;
第一字段的比特状态属于第二状态时,指示控制信息用于多个传输块的调度;
第一字段包含1个或多个比特,第一状态包括第一字段的一种或多种比特状态,第二状态包括第一字段的一种或多种比特状态。
其中,第一字段是第一信息的组成部分,例如该第一字段可以位于第一信息的头部,也可以位于第一字段的末尾,或者第一字段处于第一信息中的特定位置,此处不做限定。第一字段可以具有多种比特状态,例如第一字段至少包括:第一状态和第二状态。当第一字段的比特状态属于第一状态时,第一字段可以指示控制信息用于一个传输块的调度,例如第一状态可以是00。当第一字段的比特状态属于第二状态时,指示控制信息用于多个传输块的调度,控制信息调度的多个传输块可以是2个传输块,或者3个传输块,或者4个传输块等,例如第二状态可以是01、10、11。
在本申请实施例中,第一字段包含1个或多个比特,第一状态包括第一字段的一种或 多种比特状态,第二状态包括第一字段的一种或多种比特状态。对于第一字段包括的比特个数此处不做限定,对于第一字段包括的每种状态此处不做限定。在本申请实施例中使用第一信息中第一字段来指示控制信息用于一个传输块的调度,还是用于多个传输块的调度。使用第一字段的不同比特状态来指示控制信息调度一个传输块,或者调度多个传输块,可节省控制信息的比特开销,减少占用传输资源。
进一步的,在本申请的一些实施例中,控制信息用于多个传输块的调度,
多个传输块中的除第一个传输块以外的其它传输块的HARQ进程索引根据第一个传输块的HARQ进程索引确定;和/或,
多个传输块中的每个传输块对应一个HARQ进程索引,且多个传输块对应的多个HARQ进程索引是连续的。
其中,若控制信息调度多个传输块时,第一信息用于指示第一个传输块的HARQ进程索引,对于多个传输块中的除第一个传输块以外的其它传输块的HARQ进程索引根据第一个传输块的HARQ进程索引确定。例如其它传输块的HARQ进程索引可以使用预设的计算方式对第一个传输块的HARQ进程索引进行计算,从而得到其它传输块的HARQ进程索引。例如预设的计算方式可以包括多种计算规则,后续实施例中详细说明。对于多个传输块中的每个传输块对应一个HARQ进程索引,即每个传输块都配置有一个HARQ进程索引,而且多个传输块对应的多个HARQ进程索引是连续的,当第一信息用于指示第一个传输块的HARQ进程索引时,其它传输块的HARQ进程索引可以根据所有HARQ进程索引是连续的得到。举例说明,第一个传输块的HARQ进程索引是1,若控制信息共调度3个传输块,则其它传输块的HARQ进程索引从HARQ进程索引1开始,采用连续规则确定出其它3个传输块的HARQ进程索引是2,3,4。
进一步的,在本申请的一些实施例中,多个传输块中的除第一个传输块以外的其它传输块对应的HARQ进程索引根据第一个传输块对应的HARQ进程索引按照依次递增的顺序确定;或者,
多个传输块中的第n个传输块的HARQ进程索引的值Rn满足如下关系:
Rn={R1+n-1}mod N;
其中,R1为第一个传输块的HARQ进程索引的值,n是正整数,mod表示求模运算,N是控制信息支持的最大HARQ进程个数。
其中,多个传输块中的除第一个传输块以外的其它传输块对应的HARQ进程索引根据第一个传输块对应的HARQ进程索引还可以按照依次递减的顺序确定,此处不做限定。另外,本申请实施例中多个传输块中每个传输块对应的HARQ进程索引都可以通过上述的求模运算公式来得到。在实际应用场景下,可以结合具体场景来确定每个传输块对应的HARQ进程索引的获取方式。
在本申请的一些实施例中,第一信息包含第一字段;第一字段的比特状态属于第一状态时,指示控制信息用于一个传输块的调度。第一字段的比特状态属于第二状态时,指示控制信息用于多个传输块的调度。在这种实现场景下,进一步的,在本申请实施例中,针对控制信息调度的传输块个数的不同,第一个传输块的HARQ进程索引也可以有多种取值情况,接下来进行详细的举例说明。
在本申请的一些实施例中,控制信息用于1个传输块的调度时,第一信息在取值集合{0,1,2}内指示第一个传输块的HARQ进程索引;或,
控制信息用于2个传输块的调度时,第一信息在取值集合{0,1}或{0,2}内指示第一个传输块的HARQ进程索引;或,
控制信息用于3个传输块的调度时,第一信息在取值集合{0,1}内指示第一个传输块的HARQ进程索引;或,
控制信息用于4个传输块的调度时,第一信息指示第一个传输块的HARQ进程索引取值是0。
其中,控制信息用于1传输块的调度时,第一信息只需要从{0,1,2}内指示第一个传输块的HARQ进程索引。例如第一个传输块的HARQ进程索引可以是0,或者1,或者2。控制信息用于2个传输块的调度时,第一信息只需要在取值集合{0,1}或{0,2}内指示第一个传输块的HARQ进程索引。例如第一个传输块的HARQ进程索引可以是0,或者1,第一个传输块的HARQ进程索引可以是0或者2。控制信息用于3个传输块的调度时,第一信息只需要在取值集合{0,1}内指示第一个传输块的HARQ进程索引。例如第一个传输块的HARQ进程索引可以是0,或者1。控制信息用于4个传输块的调度时,第一信息指示第一个传输块的HARQ进程索引取值是0,此时例如控制信息调度的所有传输块的HARQ进程索引可以是0,1,2,3。详见后续实施例中表1所示的举例内容,通过上述方式,可以减少控制信息的比特开销。

不限定的是,在本申请的一些实施例中,第二通信设备指示多个传输块中的第一个传输块对应的HARQ进程索引可以有不同实施方式。例如,一种实施方式为实施方式1,即为第二通信设备只指示多个传输块中的第一个传输块对应的HARQ进程索引,多个传输块中的其他传输块(非第一个传输块)对应的HARQ进程索引根据第一个传输块对应的HARQ进程索引按照依次递增顺序或者求模运算公式确定。例如,另一种实施方式为实施方式2,即为第二通信设备指示了多个传输块中的所有传输块(包括第一个传输块)对应的HARQ进程索引。多个传输块中对应的HARQ进程索引满足依次递增顺序或者满足求模运算公式。此时,实施方式2只是实施方式1的变换。在本申请实施例中,实施方式1和实施方式2是等价的或等同的,都是第二通信设备指示多个传输块中的第一个传输块对应的HARQ进程索引的具体实施方式。

进一步的,在本申请的一些实施例中,第一个传输块个数范围为{1,3},控制信息调度A个传输块,第一信息在取值集合{0,1}指示第一个传输块的HARQ进程索引,A是取值集合{1,3}中的值。或者,
第一个传输块个数范围为{1,4},控制信息调度1个传输块时,第一信息在取值集合是{0,1,2}指示第一个传输块的HARQ进程索引,控制信息调度4个传输块时,第一信息指示的第一个传输块的HARQ进程索引取值是0。
其中,第一个传输块个数范围为{1,3}表示控制信息调度的传输块个数只能是{1,3}中的一个数值,第一信息可以指示第一个传输块的HARQ进程索引为0,或者1。或者,第一个传输块个数范围为{1,4},控制信息调度1个传输块时,第一信息指示第一个传输块的HARQ进程索引为0,或者1,或者2。控制信息调度4个传输块时,第一信息指示的第一个传输块的HARQ进程索引取值是0,则控制信息调度的其它三个传输块的HARQ进程索引为0,1,2。通过上述方式,只需要指示第一个传输块的HARQ进程索引,对于控制信息 调度的其它HARQ进程索引无需指示,可以减少控制信息的比特开销。
在本申请的一些实施例中,当第一个传输块个数范围可以是{1,3},此时第二传输块个数范围为{2,4}。当第一个传输块个数范围可以是{1,4},此时第二传输块个数范围为{2,3},接下来对第二传输块个数范围以及第一信息指示的第一个传输块的HARQ进程索引进行说明。
第二传输块个数范围为{2,4},控制信息调度2个传输块,第一信息在取值集合{0,1,2}指示第一个传输块的HARQ进程索引,控制信息调度4个传输块时,第一信息指示的第一个传输块的HARQ进程索引取值为0。或者,
第二传输块个数范围为{2,3},控制信息调度2个传输块,第一信息在取值集合{0,1}或{0,2}指示第一个传输块的HARQ进程索引,控制信息调度3个传输块时,第一信息在取值集合{0,1}指示第一个传输块的HARQ进程索引。
对于第二传输块个数范围的具体取值,第一信息所指示的第一个传输块的HARQ进程索引详见上述举例,通过上述方式,只需要指示第一个传输块的HARQ进程索引,对于控制信息调度的其它HARQ进程索引无需指示,可以减少控制信息的比特开销。
在本申请的一些实施例中,传输块信息指示控制信息调度的传输块个数,传输块信息包括2个比特。
传输块信息的比特状态是00时,指示控制信息用于一个传输块的调度。
传输块信息的比特状态是01至11中的任意一个比特状态时,指示控制信息用于多个传输块的调度。
特别地,本申请实施例中控制信息调度的一个或者多个传输块中的第一个传输块的HARQ进程索引为0或者为预设值或者为配置的值,且多个传输块对应的多个HARQ进程索引是连续的。
其中,传输块信息可以用于指示控制信息调度的传输块个数。例如传输块信息包括2个比特。控制信息调度的一个或者多个传输块中的第一个传输块的HARQ进程索引为0,且多个传输块对应的多个HARQ进程索引是连续的,此时对于每个传输块的HARQ进程索引都不需要指示,因为第一个传输块的HARQ进程索引固定为0,此时其它传输块的HARQ进程索引都可以依次得出。详见后续实施例中表3所示的举例内容,通过上述方式,无需指示传输块的HARQ进程索引,可以减少控制信息的比特开销。
在本申请的一些实施例中,高层信令为无线资源控制信令,无线资源控制信令包括第一信息;
第一信息中包括传输块信息,且传输块信息只指示控制信息调度的传输块中的第一个传输块的HARQ进程索引时,控制信息指示控制信息调度的传输块个数。或者,
第一信息中包括最大传输块个数信息和/或第一组合信息时,控制信息指示控制信息调度的传输块个数和指示控制信息调度的传输块中的第一个传输块的HARQ进程索引,或者控制信息指示控制信息调度的所有传输块的HARQ进程索引。
其中,第一信息包括传输块信息,若该传输块信息只指示控制信息调度的传输块中的第一个传输块的HARQ进程索引时,控制信息指示控制信息调度的传输块个数。因此通过传输块信息和控制信息可以确定出第一个传输块的HARQ进程索引和控制信息调度的传输 块个数。在另一种实现场景下,第一信息为高层信令,第一信息中包括最大传输块个数信息和/或第一组合信息时,控制信息可以指示控制信息调度的传输块个数和指示控制信息调度的传输块中的第一个传输块的HARQ进程索引,或者控制信息指示控制信息调度的所有传输块的HARQ进程索引。对于控制信息指示第一个传输块的HARQ进程索引,还是所有个传输块的HARQ进程索引,具体取决于应用场景,此处不做限定。
进一步的,在本申请的一些实施例中,第一信息包括传输块信息时,方法还包括:第一通信设备接收第二通信设备发送的HARQ进程索引集合信息,HARQ进程索引集合信息指示至少一个HARQ进程索引集合。
其中,第二通信设备还可以向第一通信设备发送HARQ进程索引集合信息,从而第一通信设备可以根据该HARQ进程索引集合信息确定出至少一个HARQ进程索引集合。第二通信设备可以向第一通信设备发送HARQ进程索引集合信息,从而第二通信设备进一步的向第一通信设备发送控制信息,该控制信息在第二通信设备所确定的HARQ进程索引集合中进行HARQ索引的指示和/或传输块个数的指示,因此可以减少控制信息的指示开销。
在本申请的一些实施例中,最大传输块个数取值为取值集合{2,4}或取值集合{1,2,4}中的值。本申请实施例中第二通信设备可以限定控制信息调度的最大传输块个数,从而使得控制信息只需要从取值集合{2,4}或取值集合{1,2,4}中指示具体的最大传输块个数,而不需要对所有的传输块个数进行指示,因此可以减少控制信息的指示开销。
在本申请的一些实施例中,控制信息调度的所有传输块是全部初传的传输块,或者控制信息调度的所有传输块是全部重传的传输块。
其中,全部初传的传输块指的是控制信息调度的所有传输块的传输方式都是初传,全部重传的传输块指的是控制信息调度的所有传输块的传输方式都是重传。例如控制信息中可以使用1个比特指示所有传输块是全部初传的传输块或者全部重传的传输块,从而使得通信设备通过解析该控制信息确定所有传输块采用全部初传还是全部重传。
通过前述实施例对本申请的举例说明可知,为了使第一通信设备能够获取到该第二通信设备确定的传输块个数和每个传输块对应的HARQ进程索引,第二通信设备可以生成一个第一信息,将该第一信息发送给第一通信设备,从而使得第一通信设备能够根据接收到的第一信息来获取到该第二通信设备确定的传输块个数和每个传输块对应的HARQ进程索引。为了节省控制信息的指示开销,本申请实施例中第二通信设备所生成的第一信息可以用于指示如下信息中的一种或者多种:传输块集合信息、最大传输块个数信息、传输块信息、第一组合集合信息。本申请实施例中,可以限制下行信息调度的各个传输块对应的HARQ进程索引,从而可以优化控制信息的比特开销,提升控制信息的传输性能。
为便于更好的理解和实施本申请实施例的上述方案,下面举例相应的应用场景来进行具体说明。
本申请实施例中,以第一通信设备为UE,第二通信设备为基站进行示例说明,前述的控制信息以CI进行后续示例,本申请实施例中CI调度多个传输块时,可以降低CI指示的开销,提高资源效率。
本申请实施例中,HARQ进程索引的灵活性相对于TB个数指示的灵活性来说不够重要,即本申请实施例中优先保证TB个数的灵活调度,因此,限制CI调度的各TB对应的HARQ 进程,优化CI比特开销,提升CI传输性能。
本申请实施例只需要2至3个比特就可以指示调度的TB及HARQ进程。
在本申请实施例中,第二通信设备发送第一信息给第一通信设备。第二通信设备可以是基站,或具有发送能力的设备。第一通信设备可以是用户设备,或具有接收能力的设备。第一信息可包含在高层(如RRC或媒体接入控制)信令或物理层信令中。
第一信息可包含在高层(如RRC或媒体接入控制)信令或物理层信令中。第一信息的定义如前所述,这里不再赘述。
可选地,CI调度的多个TB中不同TB对应的HARQ进程索引都相同。
可选地,第一信息指示了第一个TB的HARQ进程索引,其他TB对应的HARQ进程索引根据第一个TB的HARQ进程索引得出。
可选地,第一信息指示传输块集合信息,即指示CI可以调度的TB个数集合。或第一信息指示可以调度的最大TB数。可选地,传输块集合信息指示CI可在第一数量个传输块中调度,还是在第二数量个传输块中调度。第一信息可以是CI中携带的信息,也可以是基站通过高层信令(如无线资源控制信令或媒体接入控制信令)通知给用户设备。第一信息可以包含1个或多个比特,也或者是一个字段的一种或多种状态。
第一数量可以是一个具体的数值,也可以是包含多个数值的集合,也可以是一个数值的范围。第一数量可以是预先规定的,或者是基站配置或指示的。例如,第一数量是基站配置或指示的一个值,或者第一数量是基站配置或指示的数值集合,或者第一数量是一个预先规定的数值范围。
第二数量可以是一个具体的数值,也可以是包含多个数值的集合,也可以是一个数值的范围。第二数量可以是预先规定的,或者是基站配置或指示的。例如,第二数量是基站配置或指示的一个值,或者第二数量是基站配置或指示的数值集合,或者第二数量是一个预先规定的数值范围。
例如,第一数量等于1,第二数量为N,且1<N<M,M是预先规定的整数。
例如,第一数量是一个数值的集合,且第一数量为{1,2},第二数量是一个数值的集合,且第二数量为{3,4}。
例如,第一信息的大小是1比特。当第一信息的比特状态为0时,CI指示该CI用于一个传输块的调度,当第一信息的比特状态为1时,CI指示该CI用于2至4个传输块的调度。
例如,第一信息是第一字段的比特状态。当第一信息的比特状态是第一字段的第一状态时,CI指示该CI用于一个传输块的调度,当第一信息的比特状态是第一字段的第二状态时,CI指示该CI用于2至4个传输块的调度。
当第一信息指示CI用于第二数量个传输块的调度时,第二数量个传输块中的每个传输块都对应一个HARQ进程索引。不同传输块对应的HARQ进程索引可以不同。可选地,不同传输块对应的HARQ进程索引也可以相同。
例如,第二数量是2至4中的值。第二数量个传输块中的每个传输块对应的HARQ进程索引都不同,且第二数量个传输块对应的第二数量个HARQ进程索引是连续的。
例如,当第一信息指示CI用于第二数量个传输块的调度时,假设支持4个HARQ进程 的指示。
如,当第二数量是2时,2个传输块对应的HARQ进程索引集合是{n 0,n 1}。
如,当第二数量是3时,3个传输块对应的HARQ进程索引集合是{n 0,n 1,n 2},或3个传输块对应的HARQ进程索引集合是{n 1,n 2,n 3}。
如,当第二数量是4时,4个传输块对应的HARQ进程索引集合是{n 0,n 1,n 2,n 3}。
上述n 0,n 1,n 2,n 3是4个HARQ进程的索引。n 0,n 1,n 2,n 3的值可以是固定的,如n 0=0,n 1=1,n 2=2,n 3=3。
可选地,第二数量个传输块中的第一个传输块对应的HARQ进程索引ni是基站指示的,第二数量个传输块中的其他传输块对应的HARQ进程索引是在ni上依次递增(或递减)确定的。
如下表1例示了一种CI指示方法。
当第一信息状态为第一比特状态时,CI调度了一个TB,且该TB对应的HARQ进程是基站指示的。如用1比特从2种索引中指示该TB对应的HARQ进程索引。当第一信息状态为第二比特状态时,CI调度了2至4个TB。
CI指示调度的TB数,和指示各TB对应的HARQ进程索引。如表1,TB数是2至4时,各TB数及其分别对应的HARQ进程组合共有4种组合。因此,当指示的TB数是2至4时,可以用2比特指示CI调度的TB数,和调度的TB对应的HARQ进程索引。
表1:CI指示调度的TB数及HARQ进程索引
Figure PCTCN2019075289-appb-000001
表2a和表2b例示了CI调度了2至4个TB时,用2比特指示CI调度的TB数,和调度的TB对应的HARQ进程索引。可选地,CI只指示多TB块中的第一个TB块的HARQ进程索引(如表2a、2b的第三列)。可选地,CI指示多TB块中的各个TB块的HARQ进程索引(如表2a、2b第四列)。
当CI只指示多TB块中的第一个TB块的HARQ进程索引时,CI指示的多TB块中的其他TB块的HARQ进程索引根据第一个TB块的HARQ进程索引按照自然顺序递增(或递减)得出。如,CI指示调度了2个TB块,且第一个TB块的HARQ进程索引为m,则第二个TB块的HARQ进程索引为m+1。

如下表3例示了另一种CI指示方法。
当第一信息状态为第一比特状态时,CI调度了一个TB,且该TB对应的HARQ进程是固定的(例如为0)。当第一信息比特状态为第一字段的第二比特状态时,CI调度了多个TB,且多个TB中的第一个TB对应的HARQ进程是固定的。CI指示的多TB块中的其他TB块的HARQ进程索引根据第一个TB块的HARQ进程索引按照自然顺序递增(或递减)得出。如,第一个TB对应的HARQ进程固定为0。

如下表4例示了另一种CI指示方法。
当第一信息比特状态为第一字段的第一比特状态时,CI调度了一个TB。当第一信息比特状态为第一字段的第二比特状态时,CI调度了多个TB,且指示了多个TB中的第一个TB对应的HARQ进程索引。CI指示的多TB块中的其他TB块的HARQ进程索引根据第一个TB块的HARQ进程索引按照自然顺序递增(或递减)得出。

如下表5例示了另一种CI指示方法。
当第一信息比特状态为第一字段的第一比特状态时,CI调度了一个TB,且CI指示了该TB对应的HARQ进程索引。当第一信息比特状态为第一字段的第二比特状态时,CI调度了多个TB,且CI指示了多个TB全部为初传或全部为重传,且CI指示了多个TB中的第一个TB对应的HARQ进程索引(如表5第三列),或指示了所有TB对应的HARQ进程索引(如表5第四列)。当第一信息比特状态为第一字段的第三比特状态时,CI指示了该CI调度的多个TB中既有初传TB也有重传TB。
表5:CI指示调度的TB数及HARQ进程索引

可选地,本申请实施例中,CI中还可以包含1比特,用于指示该CI调度的TB是全部初传TB还是全部重传TB。
可选地,本申请实施例方案可以用于用户设备工作在覆盖增强模式B,或覆盖增强等级2,或覆盖增强等级3。
在本申请的另一些实施例中,例如RRC信令中的1比特或2比特作为第一信息。第一 信息指示CI可以调度的TB个数集合。如,1比特指示TB个数集合是{1,2}或TB个数集合是{3,4}。或第一信息指示DCI可以调度的最大TB数。如,指示最大TB数是2或4。再如,指示最大TB数是1、2或4。
如图4a所示,第一信息指示TB个数集合{1,2}(或指示最大TB数是2)时,RRC还用1比特从2个集合中指示一个集合作为第一集合。CI用2比特指示第一集合中的一个组合。UE根据CI的指示,确定CI调度的TB个数(即图4a的L)和第一个TB对应的HARQ进程索引(即图4a中的第一个HARQ进程索引)。其他TB对应的HARQ进程索引根据第一个TB的HARQ进程索引按照递增顺序得出。
如图4b所示,第一信息2比特指示一个集合。每个集合包含4种组合。第一信息用2比特从3个集合中指示一个集合作为第一集合。CI用2比特指示第一集合中的一个组合。UE根据CI的指示,确定CI调度的TB个数(即图4b的L)和第一个TB对应的HARQ进程索引。其他TB对应的HARQ进程索引根据第一个TB的HARQ进程索引按照递增顺序得出。
例如,第一信息指示CI可调度的TB数,或第一信息指示CI调度的最大TB数。
例如,第一信息用1比特指示调度的最大TB数是2或4。当第一信息指示调度的最大TB数是2时,CI可调度的TB数为1或2。当第一信息指示调度的最大TB数是4时,CI可调度的TB数为3或4。
再如,第一信息用1比特指示CI可调度的TB数是{1,2}或{3,4}。
如图4c所示,当CI指示调度的TB数是1或2时,第一信息还有2比特指示CI调度的第一个TB对应的HARQ进程索引(图4c的0至3)。当CI指示调度的TB数是3或4时,CI调度的第一个TB对应的HARQ进程索引固定为0。
可选地,第一信息指示CI可调度的TB数,或第一信息指示CI调度的最大TB数。
如,第一信息用1比特指示调度的最大TB数是2或4。当第一信息指示调度的最大TB数是2时,CI可调度的TB数为1或2。当第一信息指示调度的最大TB数是4时,CI可调度的TB数为3或4。
再如,第一信息用1比特指示CI可调度的TB数是{1,2}或{3,4}。
如图4d所示,当CI指示调度的TB数是1或2时,第一信息还有1比特指示CI调度的TB数及CI调度的第一个TB对应的HARQ进程索引。当DCI指示调度的TB数是3或4时,CI调度的第一个TB对应的HARQ进程索引固定为0。
本申请实施例中,CI中还可以包含1比特,用于指示该CI调度的TB是全部初传TB还是全部重传TB。
在本申请实施例中,HARQ进程索引的灵活性相对于TB个数指示的灵活性来说不够重要。因此,限制CI调度的各TB对应的HARQ进程,优化CI比特开销,提升CI传输性能。现有技术中需要4个比特指示调度的TB个数,HARQ进程索引。本申请实施例只需要2至3个比特就可以指示调度的TB及HARQ进程。
