在一种可能的设计中,下行控制信息能够调度的最多的传输块个数L是预先约定的,也就是,无需向终端设备发送该第一信息,可直接在HARQ进程号的取值范围内,向终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号,从而减少数据传输的开销。
在本申请实施例中,在HARQ进程号的取值范围内,根据下行控制信息能够调度的最多的传输块个数以及该HARQ进程号的取值范围,提供了多种可选取的设计方式用以向终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号。
例如,L=2,HARQ进程号的取值范围是[0,3]时,下行控制信息中包括指示一个或两个传输块中每个传输块对应的HARQ进程号,当该第一字段指示两个传输块对应的HARQ进程号时,该两个块对应的HARQ进程号能够是不连续的,也就是,该第一字段包括了该两个传输块对应的所有可选取的HARQ进程号组合,换而言之,可选取的HARQ进程号组合的灵活性最大,且下行控制信息能够调度的最多的传输块个数为2,即用于指示每个传输块的NDI的比特数最多为2个,从而下行控制信息的比特开销也较小。
例如,L=4,HARQ进程号的取值范围是[0,7]时,下行控制信息指示所调度的M个传输块中的第一个传输块对应的HARQ进程号,另外该下行控制信息还包括有指示M取值以及M个传输块的NDI的5个连续比特,由于下行控制信息实际调度的传输块个数最多为4,而HARQ进程号的取值范围为[0,7],意味着,M个传输块对应的可选取的HARQ进程号组合数较多,也就需要在下行控制信息中占用较大的比特开销来指示M个传输块对应的HARQ进程号的所有组合,本申请实施例中通过指示第一个传输块对应的HARQ进程号,以及在第二字段使用比特状态为1的比特在所述第二字段的位置来指示M的取值,就可以实现对M个传输块对应的M个HARQ进程号的指示,占用的比特开销较少,且第一个传输块对应的HARQ进程号不是固定的,比如M=2,第一个传输块对应的HARQ进程号的取值为[0,6]中的任一个,相当于,保障了HARQ进程号选取的灵活性。
例如,L=8,HARQ进程号的取值范围是[0,7]时,同样地,M的最大取值为8,若在下行控制信息中指示M个传输块对应的M个HARQ进程号,则需要占用较大的比特开销,本申请实施例中下行控制信息包含10个比特,通过该10个比特中除M个连续比特之外的(10-M)个连续比特指示第一个传输块对应的HARQ进程号以及M的取值,相当于在下行控制信息中仅需(10-M)个比特即可实现了对M个传输块对应的M个HARQ进程号的指示,从而减少了下行控制信息的比特开销,且状态为1的比特可以是(9-M)连续个比特中的任一个,也就是第一个传输块对应的HARQ进程号的取值是灵活的,从而保障了HARQ进程号选取的灵活性。
例如,L=4,HARQ进程号的取值范围是[0,3]时,同样地,M的最大取值为4,若在下行控制信息中指示M个传输块对应的M个HARQ进程号,则需要占用较大的比特开销, 本申请实施例中下行控制信息包含6个比特,通过该6个比特中除M个连续比特之外的(6-M)个连续比特指示第一个传输块对应的HARQ进程号以及M的取值,实现了对所有M个传输块对应的M个HARQ进程号的指示,比特开销较小,且状态为1的比特可以是(5-M)连续个比特中的任一个,也就是第一个传输块对应的HARQ进程号的取值是灵活的,保证了HARQ进程号选取的灵活性。
结合第一方面,在第一方面的一种可能的设计中,所述L=2,所述HARQ进程号的取值范围是[0,3],所述第一字段用3个连续比特指示所述一个或两个传输块中每个传输块对应的HARQ进程号,所述3个连续比特的6种状态用于指示所述下行控制信息调度所述两个传输块时每个传输块对应的HARQ进程号,且所述下行控制信息用2个连续比特指示所述两个传输块中每个传输块的NDI;和/或,
所述3个连续比特的除所述6种状态外剩余2种状态用于指示所述下行控制信息调度所述一个传输块时,所述一个传输块对应的HARQ进程号,且所述下行控制信息中有一个比特指示所述一个传输块的NDI。
也就是,在L=2,HARQ进程号的取值范围是[0,3]时,第一字段包括3个连续比特,该3个连续比特对应8种状态,通过使用该8种状态指示调度两个传输块时该两个传输块对应的两个HARQ进程号,以及调度一个传输块时该一个传输块对应的HARQ进程号,从而可以实现在下行控制信息中指示一个或多个传输块中对应的HARQ进程号的所有情况,也就意味着,HARQ进程号的选取的灵活性高,且下行控制信息最多能够调度2个传输块,即用于指示传输块的NDI的比特开销最多为2个,因而下行控制信息最多使用5个比特即可指示每个传输块对应的HARQ进程号以及每个传输块的NDI,比特开销小。
结合第一方面,在第一方面的一种可能的设计中,所述L=4,所述HARQ进程号的取值范围是[0,7],所述下行控制信息中用3个连续比特指示所述第一个传输块对应的HARQ进程号,所述第二字段中,从第一个高位比特到低位比特的第i个比特的状态为1,用于指示M的取值,所述i为(5-M),所述第i个比特的前(4-M)个比特的状态都为0,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个传输块的NDI。
也就是,在L=4,HARQ进程号的取值范围是[0,7]时,使用下行控制信息中的3个连续比特指示第一个传输块对应的HARQ进程号,3个连续比特对应8种状态,可以指示[0,7]中的任意一个HARQ进程号,意味着,第一个传输块对应的HARQ进程号是可以灵活选取的,然后使用第二字段中,从第一个高位比特到低位比特的第一个比特状态为1的比特在该第二字段中的位置指示M的取值,相当于使用较少的比特即可隐式指示调度的每个传输块对应的HARQ进程号,又由于第一个传输块对应的HARQ进程号不是固定的,故M个传输块对应的M个HARQ进程号也不是固定的,从而在保证HARQ进程号选取的灵活性的同时减少了下行控制信息的比特开销。
结合第一方面,在第一方面的一种可能的设计中,所述L=8,所述HARQ进程号的取值范围是[0,7],所述(9-M)个连续比特中,从第一个高位比特到低位比特的第j个比特用于指示所述第一个传输块对应的HARQ进程号(j-1),所述第j个比特的状态为1,所述其他的(8-M)个比特的状态都为0,所述10个比特中,从第一个高位比特到低位比特的第i个比特用于指示所述M的取值,所述第i个比特的状态为1,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个传输块的NDI。
也就是,在L=8,HARQ进程号的取值范围是[0,7]时,使用(9-M)个连续比特中, 从第一个高位比特到低位比特的第j个比特指示第一个传输块对应的HARQ进程号(j-1),即使用状态为1的比特在(9-M)个连续比特中的位置来指示第一个传输块对应的HARQ进程号,显然第j个比特的位置不是固定的,也就是第一个传输块对应的HARQ进程号不是固定的,然后使用M个连续比特之前的一个比特指示M的取值,即仅使用(10-M)个比特就可以指示M个传输块对应的M个HARQ进程号,相当于使用较少比特隐式指示调度的每个传输块对应的HARQ进程号,又由于第一个传输块对应的HARQ进程号不是固定的,故M个传输块对应的M个HARQ进程号也不是固定的,从而在保证HARQ进程号选取的灵活性的同时减少了下行控制信息的比特开销。
结合第一方面,在第一方面的一种可能的设计中,所述L=4,所述HARQ取值范围是[0,3],所述(5-M)个连续比特中,从第一个高位比特到低位比特的第j个比特用于指示所述第一个传输块对应的HARQ进程号(j-1),所述第j个比特的状态为1,所述其他的(4-M)个比特的状态都为0,所述6个比特中,从第一个高位比特到低位比特的第i个比特用于指示所述M的取值,所述第i个比特的状态为1,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个传输块的NDI。
也就是,在L=4,HARQ进程号的取值范围是[0,3]时,使用(5-M)个连续比特中,从第一个高位比特到低位比特的第j个比特指示第一个传输块对应的HARQ进程号(j-1),即使用状态为1的比特在(5-M)个连续比特中的位置来指示第一个传输块对应的HARQ进程号,显然第j个比特的位置不是固定的,也就是第一个传输块对应的HARQ进程号不是固定的,然后使用M个连续比特之前的一个比特指示M的取值,即仅使用(10-M)个比特就可以指示M个传输块对应的M个HARQ进程号,相当于使用较少比特隐式指示调度的每个传输块对应的HARQ进程号,又由于第一个传输块对应的HARQ进程号不是固定的,故M个传输块对应的M个HARQ进程号也不是固定的,从而在保证HARQ进程号选取的灵活性的同时减少了下行控制信息的比特开销。

所述L=4,所述HARQ进程号的取值范围是[0,3],所述下行控制信息包含6个比特,所述6个比特中有M个连续比特按照比特映射的方式指示所述M个传输块的NDI,所述6个比特中除所述M个比特之外的(5-M)个连续比特中有一个比特的状态为1且其他的(4-M)个比特的状态都为0,所述6个比特中除所述M个连续比特和所述(5-M)个连续比特外的一个比特的状态为1,其中M是正整数,且1≤M≤4。
在一种可能的设计中,下行控制信息能够调度的最多的传输块个数L是预先约定的,也就是,网络设备无需向终端设备发送该第一信息,终端设备可直接在HARQ进程号的取值范围内,确定下行控制信息调度的一个或多个传输块对应的HARQ进程号,从而减少数据传输的开销。
其中,第二方面或第二方面中该种设计方式所带来的技术效果可参见第一方面中不同设计方式所带来的技术效果,此处不再赘述。
结合第二方面,在第二方面的一种可能的设计中,所述在混合自动重传请求HARQ进程号的取值范围内,确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号,包括:

所述3个连续比特指示了除所述6中状态外剩余的2种状态中的一种,确定所述下行控制信息调度了1个传输块,所述3个连续比特指示的一个传输块对应的HARQ进程号,以及所述2个连续比特中,从第一个高位比特到低位比特的第一个比特指示的所述一个传输块的NDI。
也就是,在L=2,HARQ取值范围是[0,3]时,第一字段的3个连续比特对应8种状态,该8种状态中的6种状态指示调度两个传输块时该两个传输块对应的所有HARQ进程号组合,除该6种状态外剩余的2种状态指示调度一个传输块时该一个传输块对应的HARQ进程号,意味着,下行控制信息可以指示两个HARQ进程号的任意组合,也可以指示单调度的传输块对应的HARQ进程号,从而终端设备根据该3个连续比特对应状态可以直接确定每个传输块对应的HARQ进程号,减少终端设备的工作量,且HARQ进程号选取的灵活性高。
结合第二方面,在第二方面的一种可能的设计中,所述在混合自动重传请求HARQ进程号的取值范围内,确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号,包括:

也就是,在L=4,HARQ取值范围是[0,7]时,终端设备根据3个连续比特对应状态确定第一个传输块对应的HARQ进程号,再根据第二字段中,从第一个高位比特到低位比特的第一个比特状态为1的比特为该第二字段中的位置确定M的取值,从而能够确定出M个传输块中每个传输块对应的HARQ进程号,换而言之,终端设备仅需根据该3个连续比特对应的状态,以及第二字段中从第一个高位比特到低位比特的第一个比特状态为1的比特在第二字段的位置,就可以确定出M个传输块对应的M个HARQ进程号,意味着,仅使用(8-M)个比特即可确定出M个传输块中每个传输块对应的HARQ进程号,显然实施方式简单,终端设备的工作量较少,比特开销小,又由于第一个传输块对应的HARQ进程号不是固定的,从而还保障了HARQ进程号选取的灵活性。

也就是,在L=8,HARQ取值范围是[0,7]时,由于(9-M)个连续比特中,从第一个高位比特到低位比特的第一个比特状态为1的比特在(9-M)个连续比特中的位置指示了第一个传输块对应的HARQ进程号,10个比特中,从第一个高位比特到低位比特的第二个状态为1的比特在该10个比特中的位置指示了M的取值,意味着,终端设备仅需确定出该10个比特中,从第一个高位比特到低位比特的第一个比特状态为1以及第二个比特状态为1的两个比特在该10个比特中的位置,即可确定出第一个传输块对应的HARQ进程号以及M的取值,进而能够确定出M个传输块中每个传输块对应的HARQ进程号,实施方式简单,终端设备的工作量较少,又因为第一个传输块对应的HARQ进程号不是固定的,且仅需使用(10-M)个比特就可以确定出M个传输块对应的M个HARQ进程号,从而保障了HARQ进程号选取的灵活性的同时减少了下行控制信息的比特开销。
结合第二方面,在第二方面的一种可能的设计中,所述在混合自动重传请求HARQ进程号的取值范围内,确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号,包括:

也就是,在L=4,HARQ取值范围是[0,3]时,由于(5-M)个连续比特中,从第一个高位比特到低位比特的第一个比特状态为1的比特在该(5-M)个比特中的位置指示了第一个传输块对应的HARQ进程号,6个比特中,从第一个高位比特到低位比特的第二个状态为1的比特在该6个比特中的位置指示了M的取值,意味着,终端设备仅需确定出该6个比特中,从第一个高位比特到低位比特的第一个比特状态为1以及第二个比特状态为1 的两个比特在该6个比特中的位置,即可以确定出第一个传输块对应的HARQ进程号以及M的取值,进而能够确定出M个传输块中每个传输块对应的HARQ进程号,实施方式简单,终端设备的工作量较少,又因为第一个传输块对应的HARQ进程号不是固定的,且仅需使用(6-M)个比特就可以确定出M个传输块对应的M个HARQ进程号,从而保障了HARQ进程号选取的灵活性的同时减少了下行控制信息的比特开销。
结合上述第一方面或第二方面中任意一个方面的各个可能的设计,在一个可能的设计中,第一信息由无线资源控制信令,或媒体接入控制信令,或物理层信令携带。
也就是,网络设备通过无线资源控制信令向终端设备发送第一信息,或者,网络设备通过媒体接入控制信令向终端设备发送第一信息,或者,网络设备通过物理层信令发送第一信息。这样,网络设备可以选择多个信令中的任意一个信令将下行控制信息能够调度的最多的传输块个数指示给终端设备,以使终端设备获知该下行控制信息调度传输块的能力。

5)第一个传输块,是指下行控制信息调度的多个传输块对应的多个HARQ进程号中的最小HARQ进程号对应的传输块。例如,调度的3个传输块对应的3个HARQ进程号分别为0,2,5,则第一个传输块指HARQ进程号为0所对应的传输块。
6)本申请实施例中的“L”,指下行控制信息能够调度的最多的传输块的个数,L为正整数。例如,L为2、4、或8等。“Q”指下行控制信息能够调度的传输块对应的HARQ进程号的个数,例如,下行控制信息能够调度的传输块对应的HARQ进程号的取值范围为(0~Q-1),Q为正整数。例如,Q为4,则意味着下行控制信息能够调度的传输块对应的HARQ进程号的取值范围为[0,3]。“M”指下行控制信息实际调度的传输块个数,M为正整数。显然,M小于或等于L。
7)本申请实施例中的“从第一个高位比特到低位比特”指示了多个比特的一种排序方式。对于下行控制信息中的多个比特,高位比特到低位比特指该多个比特按照比特的编号或比特的序列号从小到大的排序,第一个高位比特指该多个比特中比特编号或序列号最小的比特,第一个低位比特指该多个比特中比特编号或序列号最大的比特。比如,4个比特对应的序列号分别为9,10,11,12,对于该4个比特而言,第一个高位比特为序列号为9的比特,第一个低位比特为序列号为12的比特。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多 个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。例如,第一值和第二值,只是为了区分不同的取值,而并不是表示这两个取值的内容、优先级或者重要程度等的不同。
需要注意的是,为了便于描述,下文以下行控制信息为DCI为例进行描述,但不限制于下行控制信息仅为DCI。
需要注意的是,为了便于描述,下文以传输块为TB为例进行描述,但不限制于传输块仅为TB。
前文介绍了本申请实施例所涉及到的一些名词概念,下面介绍本申请实施例涉及的技术特征。
在无线通信系统中,为了提高传输效率,可以使用一个DCI调度多个数据信道承载的多个TB,或者,一个DCI可以调度一个数据信道,该数据信道可以承载多个TB。例如,一个下行控制信息调度8个传输块时可参见图1,在图1中,一个下行控制信息调度传输块1、传输块2……传输块7、传输块8。目前,仅有调度一个TB时指示HARQ进程号以及每个TB是用于新传或用于重传的方法,比如,在DCI中使用NDI的取值是否发生翻转来指示调度的每个TB是用于新传或用于重传,再比如,在DCI中使用一个比特的两种状态分别指示调度的TB是用于新传或用于重传,然而在一个DCI调度多个TB时,如何指示该多个TB对应的HARQ进程号以及NDI并没有相应的解决方法。
若参照调度一个TB时指示HARQ进程号以及NDI的方法,那么在调度过程中,DCI需要指示多个TB中每个TB对应的HARQ进程号,以及多个TB中每个TB的NDI。例如,使用一个DCI调度4个TB,HARQ进程号的取值范围为[0,7],则DCI可以指示其中任意4个进程号(比如,0、3、5、6;再比如,1、2、4、7)对应调度的4个TB;另外,还需要4个比特按照比特映射的方式指示调度的4个TB中每个TB的NDI。尽管按照此方法可以灵活地指示所调度的TB中每个TB对应的HARQ进程号,但是当DCI能够调度的最多的TB个数较大时,按照上述方法需要使用Q个比特按照比特映射的方式指示被选择的HARQ进程号,同时需要L个比特按照比特映射的方式指示每个TB的NDI,这样共需要在DCI中占用(L+Q)个比特,增大了DCI的比特开销。
可见,如何在减少DCI的比特开销的同时,保障HARQ进程号选取的灵活性,实现更高的数据传输效率,是需要解决的问题。
鉴于此,根据本申请实施例的技术方案。在本申请实施例中,网络设备向终端设备发送DCI能够调度的最多的TB的的个数;并在HARQ进程号的取值范围内,采用多种方式中的至少一种向终端设备指示DCI调度的一个或多个TB对应的HARQ进程号,其中的一种方式中,通过使用指示一个TB对应的HARQ进程号以及M的取值来确定M个TB对应的M个HARQ进程号,在DCI调度多个TB时,可以减少DCI的比特开销,提高数据的传输效率,同时该一个TB对应的HARQ进程号的取值不是固定的,也就是,在DCI调度多个TB时,该多个TB对应的HARQ进程号的选取具有灵活性,意味着,能够保障多个TB调度的灵活性。
可参考图2,为本申请实施例的一种应用场景。图2包括网络设备和终端设备。终端设备的类型可以有多种,例如图2中的终端设备1为电视机,终端设备2为路由器,终端设备3为热水壶,终端设备4为水杯,终端设备5为手机,终端设备6为打印机。其中,终端设备5还可以作为终端设备4和终端设备6的中继,终端设备4和终端设备6的上行 通信需要通过中继的转发,即,终端设备4先将上行信号发送给终端设备5,终端设备5将接收到终端设备4的上行信号转发给网络设备,从而网络设备能够接收到来自终端设备4的上行信号。对于终端设备6来说也是同样的。但是对于下行通信,终端设备4和终端设备6都可以直接从网络设备接收下行信号,无需通过中继的转发。
图2中的网络设备例如为基站。其中,网络设备在不同的系统可以对应不同的设备,例如在第四代移动通信技术(4th generation,4G)系统中可以对应4G系统中的网络设备,例如eNB,在5G系统中可以对应5G系统中的网络设备,例如gNB。
下面结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种通信方法,请参见图3,为该方法的流程图。在下文的介绍过程中,以该方法应用于图2所示的网络架构为例。另外,该方法可由两个通信装置执行,这两个通信装置例如为第一通信装置和第二通信装置,其中,第一通信装置可以是网络设备或能够实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统;第二通信装置可以是终端设备或能够实现该方法所需的功能的通信装置,当然还可以是其他通信装置,例如芯片系统。对于第一通信装置和第二通信装置的实现方式均不做限制,例如第一通信装置可以是网络设备,第二通信装置是终端设备。其中,网络设备例如为基站。
为了便于介绍,在下文中,以该方法由网络设备和终端设备执行为例,也就是说,以第一通信装置是网络设备、第二通信装置是终端设备为例。因为本实施例是以应用在图2所示的网络架构为例,因此,下文中所述的网络设备可以是图2所示的网络架构中的网络设备,下文中所述的终端设备可以是图2所示的网络架构中的终端设备。
S31、网络设备向终端设备发送第一信息,所述第一信息指示下行控制信息能够调度的最多的传输块个数。
在无线通信系统中,为了提高传输效率,一个DCI中能够调度多个数据信道承载的多个TB,或者可以调度一个数据信道,该一个数据信道可以承载多个TB,其中,数据信道为物理下行数据信道或物理上行数据信道。在调度过程中,一方面DCI需要指示调度的TB所对应或关联的HARQ进程号,另一方面DCI需要指示调度的TB中每个TB的NDI。
本申请实施例,DCI调度M个TB时,网络设备向终端设备发送第一信息,该第一信息由无线资源控制信令携带,或由媒体接入控制信令携带,或由物理层信令携带。换而言之,网络设备向终端设备发送携带有该第一信息的无线资源控制信令,或者网络设备向终端设备发送携带有该第一信息的媒体接入控制信息,或者网络设备向终端设备发送携带有该第一信息的物理层信令。
作为一种可选的实施方式,所述DCI能够调度的最多的TB个数为预先约定的,比如预先约定DCI能够调度的最多的TB个数为2,或预先约定DCI能够调度的最多的TB个数为4,或预先约定DCI能够调度的最多的TB个数为8。
作为一种可选的实施方式,该第一信息还可以用于指示DCI能够调度的最多的TB个数集合,即网络设备向终端设备发送DCI能够调度的最多的TB个数集合,比如该集合可以是{2,4,8},或是{1,2,4,8},或是{1,2,4},或是{4,8}等,本申请实施例不限制于此。
作为另一种可选的实施方式,DCI能够调度的最多的TB个数为预先约定的,在此情况下,网络设备无需向终端设备发送该第一信息,也就是,网络设备不用执行S31。
S32、在HARQ进程号的取值范围内,网络设备向所述终端设备指示下行控制信息调 度的一个或多个传输块对应的HARQ进程号。
在HARQ进程号的取值范围内,网络设备向终端设备指示DCI调度的M个TB中的一个TB对应的HARQ进程号,其中,该一个TB可表示为第一TB,该第一TB为所述M个TB中的第一个TB;或者,网络设备向终端设备指示DCI调度的M个TB中的多个TB对应的HARQ进程号。其中,HARQ进程号的取值范围为DCI能够调度的最多的TB所对应的HARQ进程号的取值范围。
需要注意的是,上述第一TB可以是所述M个TB中的任意一个TB,比如第一TB为M个TB中的第一个TB,或第一TB为M个TB中的第M个TB,或M取值大于1时,第一TB为M个TB中的第(M-1)个TB,本申请实施例对此不作限制。在下文不作特殊说明的情况下,可以认为第一TB为M个TB中的第一个TB。
作为一种可选的实施方式,HARQ进程号的取值范围为预先约定的,比如预先约定HARQ进程号的取值范围为[0,3],意味着M个TB对应的M个HARQ进程号为0、1、2、3中的任意M个,或预先约定HARQ进程号的取值范围为[0,7],意味着M个TB对应的M个HARQ进程号为0、1、2、3、4、5、6、7中的任意M个。
作为一种可选的实施方式,网络设备根据DCI能够调度的最多的TB个数,在HARQ进程号的取值范围内,向所述终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号。
作为一种可选的实施方式,网络设备根据HARQ进程号的取值范围,在所述HARQ进程号的取值范围内,向所述终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号。
作为另一种可选的实施方式,网络设备根据DCI能够调度的最多的TB个数以及HARQ进程号的取值范围,在所述HARQ进程号的取值范围内,向所述终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号。
S33:终端设备接收来自网络设备的第一信息,以及网络设备所指示的一个或多个传输块对应的HARQ进程号之后,作为响应,在HARQ进程号的取值范围内,终端设备确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号。
在HARQ进程号的取值范围内,终端设备确定DCI调度的M个TB中的一个TB对应的HARQ进程号,其中,该一个TB可表示为第一TB,该第一TB为所述M个TB中的第一个TB;或者,网络设备确定DCI调度的M个TB中的多个TB对应的HARQ进程号。其中,HARQ进程号的取值范围为DCI能够调度的最多的TB所对应的HARQ进程号的取值范围。
作为一种可选的实施方式,DCI能够调度的最多的TB个数为预先约定,终端设备在接收到来自网络设备所指示的一个或多个传输块对应的HARQ进程号之后,在HARQ进程号的取值范围内,确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号。
作为一种可选的实施方式,所述HARQ进程号的取值范围为预先约定的,比如预先约定HARQ进程号的取值范围为[0,3],意味着M个TB对应的M个HARQ进程号为0、1、2、3中的任意M个,或预先约定HARQ进程号的取值范围为[0,7],意味着M个TB对应的M个HARQ进程号为0、1、2、3、4、5、6、7中的任意M个。
作为一种可选的实施方式,终端设备根据DCI能够调度的最多的TB个数,在HARQ进程号的取值范围内,确定下行控制信息调度的一个或多个传输块对应的HARQ进程号。
作为一种可选的实施方式,终端设备根据HARQ进程号的取值范围,在所述HARQ进程号的取值范围内,确定下行控制信息调度的一个或多个传输块对应的HARQ进程号。
作为另一种可选的实施方式,终端设备根据DCI能够调度的最多的TB个数以及HARQ进程号的取值范围,在所述HARQ进程号的取值范围内,确定下行控制信息调度的一个或多个传输块对应的HARQ进程号。
在前述S31中,即在HARQ进程号的取值范围内,网络设备向所述终端设备指示下行控制信息调度的一个或多个传输块对应的HARQ进程号时,关于如何在DCI中调度M个TB,可以包括多种实现方式,下面举例介绍。
方式一:网络设备根据HARQ进程号的取值范围,以及DCI能够调度的最多的TB个数,在HARQ进程号的取值范围内,实现对所述M个TB的调度;具体地,L=2时,网络设备使用DCI中
个比特来指示所述M个TB,其中,
个比特中的
个连续比特指示M个TB中的每个TB对应的HARQ进程号,
个比特中除
个连续比特之外的剩余2个连续比特按照比特映射的方式指示M个TB中的每个TB的NDI;L>2时,网络设备使用DCI中
个比特来指示M个TB,其中,
个比特中的
个连续比特指示M个TB中的每个TB对应的HARQ进程号,
个比特中除
个连续比特之外的连续L个比特按照比特映射的方式指示M个TB中的每个TB的NDI。
显然,上述方式一中的
所指示的HARQ进程号组合或
所指示的HARQ进程号组合可以隐式指示DCI实际调度的TB的个数,即隐式指示M的取值,且M个TB对应的M个HARQ进程号可以是连续排列的,也可以是非连续排列的。
需要注意的是,在上述方式一中,L=2时,在
个比特中,从第一个高位比特到低位比特,
个连续比特可以位于L个连续比特的前面或后面,本申请实施例不限制于此。同样地,L>2时,在
个比特中,从第一个高位比特到低位比特,
个连续比特可以位于L个连续比特的前面或后面,本申请实施例不限制于此。下文在不进行特殊说明的情况下,可认为在DCI中,从第一个高位比特到低位比特的所述
或所述
个连续比特位于所述L个连续比特的前面。
下面对上述方式一的具体实现方式,进行详细介绍。
在L=2时,在Q个HARQ进程号中任意选取2个HARQ进程号用来指示能够调度的M个TB,这样就有
种组合,从而在DCI中需要
个连续比特来指示M个TB中的每个TB对应的HARQ进程号;另外还需要L个连续比特按照比特映射的方式指示M个TB中的每个TB的NDI,这样,在DCI中就需要
个比特来实现对M个TB的调度。例如Q=4时,网络设备需要在DCI中使用5个比特来调度M个TB,该5个比特 中的3个连续比特用于指示每个TB对应的HARQ进程号,该5个比特中除该3个连续比特之外的2个连续比特按照比特映射的方式指示M个TB中每个TB的NDI;例如Q=8时,网络设备需要在DCI中使用7个比特来调度M个TB,该7个比特中的5个连续比特用于指示M个TB中每个TB对应的HARQ进程号,该7个比特中除该5个连续比特之外的2个连续比特按照比特映射的方式指示M个TB中每个TB的NDI。
在L>2时,在Q个HARQ进程号中任意选取L个HARQ个进程号用来指示可能调度的L个TB,这样就有
种组合,在Q个HARQ进程中任意选取(L-1)个HARQ进程号用来指示可能调度的(L-1)个TB,这样就有
种组合,依次类推,在L>2时,DCI能够调度的TB对应的可选取的HARQ进程号的组合数为
从而需要
个连续比特来指示M个TB中的每个TB对应的HARQ进程号;另外还需要L个连续比特按照比特映射的方式指示M个TB中每个TB的NDI;这样,在DCI中就需要
个比特实现M个TB的调度。比如,L=4,Q=4时,网络设备可能需要在DCI占用8个比特来实现M个TB的调度,该8个比特中4个连续比特用于指示M个TB中的每个TB对应的HARQ进程号,该8个比特中除该4个连续比特之外剩余4个连续比特按照比特映射的方式指示调度的每个TB的NDI。比如,L=4,Q=8时,网络设备可能需要在DCI占用12个比特来实现M个TB的调度,该12个比特中的8个连续比特指示调度的每个TB对应的HARQ进程号,该12个比特中除该8个连续比特之外剩余4个连续比特按照比特映射的方式指示调度的每个TB的NDI。再比如,L=8,Q=8时,网络设备可能需要在DCI占用17个比特来调度M个TB,该17个比特中的9个连续比特指示调度的每个TB对应的HARQ进程号,该17个比特中除该9个连续比特之外剩余的8个连续比特按照比特映射的方式指示调度的每个TB的NDI。
示例性地,L=2,Q=4,即DCI能够调度的最多的TB个数为2,HARQ进程号的取值范围为[0,3]时,按照上述方式一可以确定出需要在DCI中占用5个比特用于指示所调度的M个TB,如表1.1所示,该5个比特中的3个连续比特指示调度的1个或2个TB中每个TB对应的HARQ进程号,除该3个连续比特之外剩余的2个连续比特按照比特映射的方式指示调度的1个或2个TB中每个TB的NDI。
表1.1:DCI中用于指示所调度的M个TB的比特数
指示每个TB对应的HARQ进程号的比特数 | 用于新传或重传的比特数 |
3bit | 2bit |
参见表1.2,示例性地示出了表1.1中3个连续比特的一种指示方式;如表1.2所示,2个TB对应的HARQ进程号分别为0、1时,网络设备将该3个比特设置为000;2个TB对应的HARQ进程号分别为0、2时,网络设备将该3个比特设置为001;2个TB对应的HARQ进程号分别为0、3时,网络设备将该3个比特设置为010;2个TB对应的HARQ进程号分别为1、2时,网络设备将该3个比特设置为011;2个TB对应的HARQ进程号 分别为1、3时,网络设备将该3个比特设置为100;2个TB对应的HARQ进程号分别为2、3时,网络设备将该3个比特设置为101。另外,3个连续比特对应的8种状态中除前述的6种状态之外的剩余2种状态可以指示单TB的调度,比如1个TB对应的HARQ进程号分别为0时,网络设备将该3个比特设置为110;1个TB对应的HARQ进程号分别为2时,网络设备将该3个比特设置为111。
表1.2:一种指示方式
HARQ进程号 | 0、1 | 0、2 | 0、3 | 1、2 | 1、3 | 2、3 | 0 | 2 |
3个比特 | 000 | 001 | 010 | 011 | 100 | 101 | 110 | 111 |
按照上述方式一,DCI可以实现对一个或多个TB的调度,DCI调度多个TB时,可选择的HARQ进程号的组合数多,意味着,多个TB调度的灵活性高,但当L、Q较大时,DCI的比特开销较大,且当M的取值小于L时,连续L个比特指示M个TB中每个TB的NDI中有(L-M)个比特未使用,比如,L=8,Q=8时,按照上述方式一,需要在DCI中占用17个比特来调度多个比特。
但需要说明的是,上述方式一在具体实现时,DCI的比特开销与M的取值有关,比如L=4,Q=8时,按照上述方式一,在DCI中需要占用12个比特实现对M个TB的调度,但在实际应用中,为了减少DCI的比特开销,M取值的最大值为4,当M取值为2时,仅需要2个连续比特按照比特映射的方式指示每个TB的NDI,也就是说,仅需要占用DCI的10个比特即可完成对该2个TB的调度,该10个比特中的另外8个连续的比特指示该2个TB对应的2个HARQ进程号。也就是说,当L=2时,在DCI中需要占用
个比特,当L>2时,在DCI中需要占用
个比特。当然,在对DCI的比特开销不敏感的情况下,可以预留L个连续比特按照比特映射的方式指示M个TB中每个TB的HARQ进程号。
方式二:网络设备根据DCI能够调度的最多的TB个数,以及HARQ进程号的取值范围,在HARQ进程号的取值范围内,实现对所述M个TB的调度;具体地,网络设备使用DCI中的
个比特来指示所述M个TB,该
个比特中的
个连续比特用于指示第一TB对应的HARQ进程号,该
个比特中除该
个连续比特之外剩余的(L+1)个连续比特用于指示M的取值以及M个TB中的每个TB的NDI,其中第一TB为第一个TB。
在方式二中,HARQ进程号取值范围内可选取的HARQ进程号的个数为Q,第一TB对应的HARQ进程号可以为该Q个HARQ进程号的中任意一个,从而在DCI中需要
个连续比特来指示第一TB对应的HARQ进程号;另外还需要(L+1)连续个比特指示M的取值以及M个TB中每个TB的NDI,在该(L+1)个连续比特中,从第一个高位比特到低位比特的(L+1-M)个连续比特指示M的取值,在该(L+1)个连续比特中除该(L+1-M)个连续比特之外剩余的M个连续比特按照比特映射的方式指示M个TB的每个TB的NDI。
其中,在该(L+1-M)个比特中,从第一个高位比特到低位比特的第(L+1-M)个比特的状态为1,在该(L+1-M)个比特中除第(L+1-M)个比特以外的比特状态为0,该第(L+1-M)个比特之后的M个连续比特按照比特映射的方式指示M个TB中每个TB的NDI,意味着,该(L+1-M)个比特中,从第一个高位比特到低位比特的第一个状态为1的比特在所述(L+1-M)个比特中的位置指示M的取值,即从第一个高位比特到低位比特的第一个状态为1的比特在该(L+1-M)个比特的位置指示M的取值,也就是说,在该(L+1-M)个比特中,从第一个高位比特到低位比特的第一个状态为1的比特为第i个比特,i为(L+1-M),则M的取值为(L+1-M-i)。
需要注意的是,一个比特在多个比特中的位置,可以根据该多个比特的编号、标识、序列号等确定。比如,3个比特对应的编号分别是6,8,7,从高位比特到低位比特,编号为7的比特在该3个比特的位置,可以用第2个来表示。
需要注意的是,上述方式二中,在该
个比特中,从第一个高位比特到低位比特,用于指示第一TB对应的HARQ进程号的
个连续比特可以位于(L+1)个连续比特的前面,或后面,本申请实施例对此不作限定,在下文不做特殊说明的情况下,可认为在DCI汇总,从第一个高位比特到低位比特的
个连续比特可以位于(L+1)个连续比特的前面。
还需要注意的是,上述方式二还可以从低位比特到高位比特确定M的取值,比如,在该(L+1-M)个比特中,从第一个低位比特到高位比特的第(L+1-M)个比特的状态为1,从而该(L+1-M)个比特中,从第一个低位比特到高位比特的第一个状态为1的比特在该(L+1-M)个比特的位置指示M的取值。
举例而言,L=2,Q=4时,网络设备需要在DCI中占用5个比特指示M个TB,该5个比特中的2个连续比特指示第一TB对应的HARQ进程号,除该2个连续比特之外剩余的3个连续比特指示M的取值以及M个TB中每个TB的NDI。比如,L=2,Q=8时,网络设备需要在DCI占用6个比特指示M个TB,该6个比特中的3个连续比特指示第一TB对应的HARQ进程号,除该3个连续比特之外剩余的3个连续比特指示M的取值以及M个TB中每个TB的NDI。比如,L=4,Q=4时,网络设备需要在DCI占用7个比特指示M个TB,该7个比特中的2个连续比特指示调度的第一TB对应的HARQ进程号,除该2个连续比特之外剩余的5个连续比特指示M的取值以及M个TB中每个TB的NDI。比如,L=4,Q=8时,网络设备需要在DCI占用8个比特指示M个TB,该8个比特中的3个连续比特用于指示调度的第一TB对应的HARQ进程号,除该3个连续比特之外剩余的5个连续比特指示M的取值以及M个TB中每个TB的NDI。再比如,L=8,Q=8时,网络设备需要在DCI占用12个比特指示所调度的M个TB,该12个比特中的3个连续比特用于指示调度的第一TB对应的HARQ进程号,除该3个连续比特之外剩余的9个连续比特指示M的取值以及M个TB中每个TB的NDI。
示例性地,L=4,Q=8,即DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,7]时,按照上述方式二可以确定出需要在DCI中占用8个比特用于指示所调度的M个TB,如表2.1所示,该8个比特中的3个连续比特用于指示第一HARQ进程号,该8个比特中除该3个连续比特之外剩余的5个连续比特用于指示M的取值以及M个TB中每个TB的NDI。
表2.1:DCI中用于指示M个TB的比特数
指示第一HARQ进程号的比特数 | 指示M取值以及每个TB的NDI |
3bit | 5bit |
参见表2.2,示例性地示出了表2.1中所示的8个比特的一种指示方式;如表2.2所示,M=4时,网络设备使用DCI中的3个连续比特来指示第一TB对应的HARQ进程号为0~4中的任一个,比如网络设备设置该3个比特为010来指示该第一TB对应的HARQ进程号为2,那么剩余3个TB对应的HARQ进程号分别为3、4、5,比如网络设备设置该3个比特取值为100来指示该第一TB对应的HARQ进程号为4,那么剩余3个TB对应的HARQ进程号分别为5、6、7,另外,网络设备还需要将DCI中的5个比特设置为“1****”来指示M的取值以及M个TB中每个TB的NDI;M=3时,网络设备使用DCI中的3个连续比特来指示第一TB对应的HARQ进程号为0~5中的任一个,另外,网络设备还需要将DCI中的5个比特设置为“01***”来指示M的取值以及M个TB中每个TB的NDI;M=2时,网络设备使用DCI中的3个连续比特来指示第一TB对应的HARQ进程号为0~6中的任一个,另外,网络设备还需要将DCI中的5个比特设置为“001**”来指示M的取值以及M个TB中每个TB的NDI;M=1时,网络设备使用DCI中的3个连续比特来指示第一TB对应的HARQ进程号为[0,7]中的任一个,另外,网络设备还需要将DCI中的5个比特设置为“0001*”来指示调度的1个TB以及该TB是用于新传或用于重传。
表2.2:一种指示方式
按照上述方式二,DCI可用于指示一个或多个TB的调度,DCI调度多个TB时,需要在DCI中占用
个比特,其中的连续
个比特用于指示第一TB对应的HARQ进程号,意味着第一TB对应的HARQ进程号是不固定的,可选择的HARQ进程号的组合数并不单一,保障了多个TB调度的灵活性,比如,L=8,Q=8时,按照上述方式二,需要在DCI中占用12个比特来调度M个TB。
需要注意的是,本申请实施例中的“*”仅示例性地指示M个TB中每个TB的NDI。
需要注意的是,上述方式二中,第一TB为第一个TB,当然,该第一TB也可以为M 个TB中的任意一个,比如,第一TB为M个TB中的第二个TB,在终端设备确定出第一TB对应的HARQ进程号为3,M取值为3时,该M个TB对应的M个HARQ进程号分别为2,3,4。
方式三:网络设备根据HARQ进程号的取值范围,在HARQ进程号的取值范围内,实现对M个TB的调度;具体地,网络设备使用DCI中的(Q+2)个连续比特指示所述M个TB,该(Q+2)个连续比特中,从第一个高位比特到低位比特的(Q+1-M)个连续比特指示第一TB对应的HARQ进程号,除该(Q+1-M)个连续比特之外剩余的(M+1)连续个比特指示所述M的取值以及M个TB中的每个TB的NDI。
在上述方式三中,HARQ进程号的取值范围为0~Q-1,DCI实际调度的TB的个数为M,利用在(Q+2)个连续比特中,从第一个高位比特到低位比特第一个状态为1的比特在所述(Q+2)个比特的位置来指示第一TB对应的HARQ进程号,第二个状态为1的比特在所述(Q+2)个比特的位置来指示M的取值(,在所述第二个状态为1的比特的后面的M个连续比特按照比特映射的方式指示M个TB中每个TB的NDI。
这样,网络设备需要从第一个高位比特到低位比特的(Q+1-M)个连续比特指示第一TB对应的HARQ进程号,另外在DCI中需要(1+M)个连续比特指示M的取值以及M个TB中每个TB的NDI。
其中,假设第一TB对应的HARQ进程号为(j+1),所述(Q+1-M)个连续比特中,从第一个高位比特到低位比特的第j个比特的状态为1,所述(Q+1-M)个连续比特中除所述第j个比特之外的其余比特的状态为0,换而言之,所述(Q+2)个连续比特中,从第一个高位比特到低位比特,该第j个比特为第一个状态为1的比特;比如,Q=4,M=2,第一TB对应的HARQ进程号可以为0~2中的任一个,网络设备需要在DCI中占用3个连续比特来指示第一TB对应的HARQ进程号,第一TB对应的HARQ进程号为0时,该3个连续比特为100,第一TB对应的HARQ进程号为1时,该3个连续比特为010,第一TB对应的HARQ进程号为2时,该3个连续比特为001;在该(L+1)个连续比特中;(Q+2)个连续比特中,从第一个高位比特到低位比特的第二个状态为1的比特在该(L+1)个连续比特的位置用于指示M的取值,即所述第二个状态为1的比特为所述(Q+2)个比特中从第一个高位比特到低位比特的第i个比特,显然所述i为(Q+2-M),则所述M的取值为(Q+2-i),该第i个比特后面剩余的M个连续比特按照比特映射的方式指示M个TB中每个TB的NDI。
需要注意的是,上述方式三中还可以从第一个低位比特到高位比特来确定指示第一TB对应的HARQ进程号的比特在该连续(Q+2)个比特中的位置,以及指示M取值的比特在该连续(Q+2)个比特中的位置。
还需要注意的是,上述中方式三的具体实现过程,第一TB为M个TB中的第一个TB,当然,该第一TB也可以是M个TB中除第一个TB之外的其它TB,本申请实施例对此不作限定,比如第一TB为M个TB中的第m个TB,第一TB对应的HARQ进程号为(i-1),按照上述方式三,需要将所述(Q+1-M)个比特中,从第一个高位比特到低位比特的第(i+m-1)个比特的状态置为1,除该第(i+m-1)个比特之外的其余比特的状态置为0。
这样,在本申请实施例的方式三中,网络设备需要在DCI中占用(Q+2)个连续比特来调度M个TB。
举例而言,L=2,Q=4时,网络设备需要在DCI中占用6个连续比特指示M个TB, 该6个连续比特中的(5-M)个连续比特指示调度的第一TB对应的HARQ进程号,剩余的(M+1)个连续比特指示M的取值以及M个TB中每个TB的NDI。比如,L=2,Q=8时,网络设备需要在DCI占用10个连续比特调度M个TB,该10个来比特中的(9-M)个连续比特用于指示调度的第一TB对应的HARQ进程号,除该(9-M)个连续比特之外剩余的(M+1)个连续比特用于指示M的取值以及M个TB中每个TB的NDI。比如,L=4,Q=4时,网络设备需要在DCI占用6个连续比特调度M个TB,该6个来比特中的(5-M)个连续比特用于指示调度的第一TB对应的HARQ进程号,除该(5-M)个连续比特之外剩余的(M+1)个连续比特用于指示M的取值以及M个TB中每个TB的NDI。比如,L=4,Q=8时,网络设备需要在DCI占用10个连续比特来调度M个TB,该10个比特中的(9-M)个连续比特用于指示调度的第一TB对应的HARQ进程号,除该(9-M)个连续比特之外剩余的(M+1)个连续比特用于指示M的取值以及M个TB中每个TB的NDI。再比如,L=8,Q=8时,需要在DCI占用10个连续比特用于指示所调度的M个TB,该10个连续比特中的(9-M)个连续比特用于指示调度的第一TB对应的HARQ进程号,除该(9-M)个连续比特之外剩余的(M+1)个连续比特用于指示M的取值以及M个TB中每个TB的NDI。
示例性地,Q=8,L=8,即DCI能够调度的最多的TB个数为8,HARQ进程号的取值范围为[0,7]时,按照上述方式三可以确定出需要在DCI中占用10个连续比特指示所调度的M个TB,如表3.1所示,该10个用于比特中的(9-M)个连续比特指示第一HARQ进程号,除该(9-M)个用于比特之外剩余的(M+1)个连续比特用于指示M的取值以及M个TB中每个TB的NDI。
表3.1:DCI中用于指示M个TB的比特数
指示第一TB对应的HARQ进程号 | 指示M取值以及每个TB的NDI |
(9-M)bit | (M+1)bit |
参见表3.2,示例性地示出了表3.1所示的10个连续比特的一种指示方式,其中,第一TB为第一个TB;如表3.2所示,M=8,第一TB对应的HARQ进程号为0时,网络设备将DCI中的10个连续比特设置为“11********”来调度8个TB;M=7,第一TB对应的HARQ进程号为0,或为1时,相应地,网络设备将DCI中的10个连续比特设置为“101*******”,或“011*******”来调度7个TB;M=6,第一TB对应的HARQ进程号为0,或为1,或为2时,相应地,网络设备将DCI中的10个连续比特设置为“1001******”,或“0101******”,或“0011******”来调度6个TB;M=5,第一TB对应的HARQ进程号为0,或为1,或为2,或为3时,相应地,网络设备将DCI中的10个连续比特设置为“10001*****”,或“01001*****”,或“00101*****”,或“00011*****”来调度5个TB;M=4,第一TB对应的HARQ进程号为0,或为1,或为2,或为3,或为4时,相应地,网络设备将DCI中的10个连续比特设置为“100001****”,或“010001****”,或“001001****”,或“000101****”,或“000011****”来调度4个TB;M=3,第一TB对 应的HARQ进程号为0,或为1,或为2,或为3,或为4,或为5时,相应地,网络设备将DCI中的10个连续比特设置为“1000001***”,或“0100001***”,或“0010001***”,或“0001001***”,或“0000101***”,或“0000011***”来调度3个TB;M=2,第一TB对应的HARQ进程号为0,或为1,或为2,或为3,或为4,或为5,或为6时,相应地,网络设备将DCI中的10个连续比特设置为“10000001**”,或“01000001**”,或“00100001**”,或“00010001**”,或“00001001**”,或“00000101**”,或“00000011**”来调度2个TB;另外,上述方式三还可以用于指示单TB的调度,比如,将网络设备将DCI中的10个连续比特设置为“100000001*”,或“010000001*”,或“001000001*”,或“000100001*”,或“000010001*”,或“000001001*”,或“000000101*”,或“000000011*”来指示第一TB对应的HARQ进程号为[0,7]中的一个。
表3.2:一种指示方式
按照上述方式三,DCI可以实现对一个或多个TB的调度,DCI调度多个TB时,需要在DCI中占用(Q+2)个连续比特,其中的(Q+1-M)个连续比特指示第一TB对应的HARQ进程号,意味着第一TB对应的HARQ进程号是不固定的,可选择的HARQ进程号的组合数并不单一,保障了多个TB调度的灵活性。
方式四:预先定义第一TB对应的HARQ进程号为0,网络设备根据DCI能够调度的最多的TB个数,在HARQ进程号的取值范围内,实现对M个TB的调度;具体地,网络设备使用DCI中(L+1)个连续比特来指示M的取值以及M个TB中每个TB的NDI,其中,该(L+1)个连续比特中的(L+1-M)个连续比特用于指示M的取值,除该(L+1-M)个连续比特之外剩余的M个连续比特用于指示M个TB中的每个TB的NDI。
在方式四中,网络设备使用比特的状态来指示M的取值,这样就需要在DCI中占用(L+1-M)个连续比特来指示M的取值,其中,该(L+1-M)个连续比特中,从第一个高位比特到低位比特的第i个比特的状态为1,除该第i个比特之外的其余比特的状态为0,第i个比特之后的M个连续比特按照比特映射的方式指示M个TB中的每个TB的NDI,换而言之,该第i个比特为该(L+1)个比特中,从第一个高位比特到低位比特的第一个状态为1的比特,显然该i为(L+1-M),故M的取值为(L+1-i)。
这样,本申请实施例中的上述方式四中,网络设备需要在DCI使用(L+1)个连续比特来调度M个TB。
需要注意的是,在上述方式四中还可以从第一个低位比特到高位比特将第i个比特的状态置为1,也就是说,在(L+1)个连续比特中,从第一个低位比特到高位比特的第一个状态为1的比特为该第i个比特,本申请实施例对此不作限定。
举例说明,L=2时,网络设备需要在DCI中使用3个连续比特来指示M个TB,该3 个连续比特中的(3-M)个连续比特用于指示M的取值,除该(3-M)个连续比特之外剩余的M个连续比特按照比特映射的方式指示调度的每个TB的NDI。比如L=4时,网络设备需要在DCI中占用5个连续比特来指示调度的M个TB,该5个连续比特中的(5-M)个连续比特用于指示M的取值,除该(5-M)个连续比特之外剩余的M个连续比特按照比特映射的方式指示调度的每个TB的NDI。L=8时,网络设备需要在DCI中占用9个连续比特来指示调度的M个TB,该9个连续比特中的(9-M)个连续比特用于指示M的取值,除该(9-M)个连续比特之外剩余的M个连续比特按照比特映射的方式指示调度的每个TB的NDI。
示例性地,L=8,即DCI能够调度的最多的TB个数为8,按照上述方式四可以确定网络设备需要在DCI中使用9个连续比特用于指示所调度的M个TB;如表4所示,网络设备使用DCI中的9个连续比特来指示M的取值以及M个TB中每个TB的NDI;M=8时,网络设备将DCI中的9个连续比特设置为“1********”来指示调度的8个TB;M=7时,网络设备将DCI中的9个连续比特设置为“01*******”来指示调度的7个TB;M=6时,网络设备将DCI中的9个连续比特设置为“001******”来指示调度的6个TB;M=5时,网络设备将DCI中的9个连续比特设置为“0001*****”来指示调度的5个TB;M=4时,网络设备将DCI中的9个连续比特设置为“00001****”来指示调度的4个TB;M=3时,网络设备将DCI中的9个连续比特设置为“000001***”来指示调度的3个TB;M=2时,网络设备将DCI中的9个连续比特设置为“0000001**”来指示调度的2个TB;M=1时,网络设备将DCI中的9个连续比特设置为“00000001*”来指示调度的1个TB。
表4:一种指示方式
示例性地,L=4,第一个TB对应的HARQ进程号为0,参见表5,网络设备使用DCI中的5个连续比特来指示M的取值以及M个TB中每个TB的NDI;M=4时,网络设备将DCI中的5个连续比特设置为“1****”来指示调度的4个TB;M=3时,网络设备将DCI中的5个连续比特设置为“01***”来指示调度的3个TB;M=2时,网络设备将DCI中的5个连续比特设置为“001**”来指示调度的2个TB;M=1时,网络设备将DCI中的5个连续比特设置为“0001*”来指示调度的1个TB。
表5:一种指示方式
上述方式四中,第一个TB对应的HARQ进程号预先约定为固定值,即第一个TB对应的HARQ进程号是固定的,可选择的HARQ进程号组合数减少,相当于,多个TB的调度缺乏灵活性,给HARQ进程号的指示和使用带来了限制,但是将DCI的比特开销从(L+Q)减少到(L+1),在DCI调度多个TB时,在DCI中仅需占用(L+1)比特,也就是说,最大程度地减少了DCI的比特开销,从而提高
需要注意的是,DCI中仅指示第一TB对应的HARQ进程号时,其余(M-1)个TB对应的(M-1)个HARQ进程号可根据预先约定的排列规则来确定。比如,预先约定的排列规则为M个TB对应的M个HARQ进程号连续排列(连续递增排列或连续递减排列),比如0、1、……、Q-1;或M个TB对应的M个HARQ进程号偶数排列,比如0、2、……、Q-2;或M个TB对应的M个HARQ进程号奇数排列,比如1、3、……、Q-1;本申请实施例不限制于此。在下文不作特殊说明的情况下,可以认为M个TB对应的M个HARQ进程号连续排列。
还需要注意的是,在前述内容中,利用比特状态为1来指示第一TB对应的HARQ进程号,或M的取值,显然,也可以用比特状态为0,其余相关比特的状态置为1来指示第一TB对应的HARQ进程号,或M的取值。
请参考表6,示出了按照上述四种方式分别需要的DCI比特开销,在L=2,Q=4时,按照方式一需要在DCI中使用5个比特,按照方式二需要在DCI中使用5个比特,按照方式三需要在DCI中使用6个比特,按照方式四需要在DCI中使用3个比特;在L=4,Q=4时,按照方式一需要在DCI中使用8个比特,按照方式二需要在DCI中使用7个比特,按照方式三需要在DCI中使用6个比特,按照方式四需要在DCI中使用5个比特;在L=4,Q=8时,按照方式一需要在DCI中使用12个比特,按照方式二需要在DCI中使用8个比特,按照方式三需要在DCI中使用10个比特,按照方式四需要在DCI中使用5个比特;在L=8,Q=4时,按照方式一需要在DCI中使用17个比特,按照方式二需要在DCI中使用12个比特,按照方式三需要在DCI中使用10个比特,按照方式四需要在DCI中使用9个比特。

在S32中,考虑到DCI的比特开销以及TB调度的灵活性,在HARQ进程号的取值范围内,就网络设备如何向所述终端设备指示DCI调度的一个或多个TB对应的HARQ进程 号,可使用如下情况1~情况5中的至少一个来实现,下面举例介绍。
情况1:DCI能够调度的最多的TB个数为2,HARQ进程号的取值范围为[0,3]时,可以采用上述方式一指示调度的M个TB,这样需要占用DCI中的5个比特,根据上述方式一,DCI包括第一字段,该第一字段指示了一个或者两个TB中每个TB对应的HARQ进程号,且当该第一字段指示两个TB对应的HARQ进程号时,两个TB对应的HARQ进程号能够是不连续的,且DCI还按照比特映射的方式指示每个TB的NDI。
进一步地,该第一字段用3个连续比特指示一个或两个TB中每个TB对应的HARQ进程号,3个连续比特的6种状态用于指示所述DCI调度两个TB时每个TB对应的HARQ进程号,且所述DCI用2个连续比特指示所述两个TB中每个TB的NDI。
进一步地,3个连续比特的8种状态中除所述6种状态外剩的余2种状态用于指示所述DCI调度所述一个TB时,该一个TB对应的HARQ进程号,且所述DCI中有一个比特指示所述一个TB的NDI。
对于情况1,网络设备根据M、M个TB中的每个TB对应的HARQ进程号以及M个TB中的每个TB的NDI,按照上述方式一,将DCI中的5个比特中的3个连续比特用于指示M个TB中每个TB对应的HARQ进程号,所述DCI中的5个比特中的除该3个连续比特中的剩余的M个连续比特用于指示M个TB中的每个TB的NDI(当M为1时,使用1个比特指示该1个TB的NDI)。其中,从第一个高位比特到低位比特,请参见表2.2,所述3个连续比特可以位于所述2个连续比特的前面,或所述3个连续比特可以位于所述2个连续比特的后面,比如,M=2时,2个TB对应的HARQ进程号为0、3,DCI中的5个比特可以设置为“010**”,或设置为“**010”。
在情况1中,3个连续比特用于指示M个TB中每个TB对应的HARQ进程号,3个连续比特对应8种状态,而M最大取值为2,有4个HARQ进程号可以选择,也就是说,2个TB对应的HARQ进程号的组合数为6种,显然,该3个比特对应的8种状态可以指示所有该2个TB对应的HARQ进程号的组合,即在M=2时,该3个连续比特可以用于指示每个TB对应的HARQ进程号,请参见表2.2,该8种状态中剩余的2个状态还可以用于指示单TB的调度,可见,情况1所描述的实施方式实现了在DCI中最大灵活度地调度多个TB,同时,对DCI的比特开销也较少。
情况2:DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,7]时,采用上述方式二指示调度的M个TB,1≤M≤4,这样需要占用DCI中的8个比特,根据上述方式二,DCI需要指示M个TB中的第一TB对应的HARQ进程号,DCI包括有5个连续比特的第二字段,所述第二字段中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述第二字段中其余(5-M)个比特中有(4-M)个比特的比特状态都是0且除所述(4-M)个比特之外的一个比特的比特状态是1。其中,第一TB为第一个TB,M个TB对应的M个HARQ进程号是连续的。
进一步地,DCI中用3个连续比特指示所述第一个TB对应的HARQ进程号,所述第二字段中,从第一个高位比特到低位比特的第i个比特的状态为1,用于指示M的取值,所述i为(5-M),所述第i个比特的前(4-M)个比特的状态都为0,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个TB的NDI。
对于情况2,网络设备根据M、第一TB对应的HARQ进程号以及M个TB中的每个TB的NDI,按照上述方式二,将DCI中的8个比特中的3个连续比特用于指示第一TB 对应的HARQ进程号,所述8个比特中的除该3个连续比特之外的5个连续比特用于指示M的取值以及M个TB中的每个TB的NDI,在所述除3个比特之外的5个连续比特中,从第一个高位比特到低位比特,将第i个比特的状态置为1,所述第i个比特之前的比特的状态置为0,第i个比特之后的连续M个比特按照比特映射的方式指示M个TB中的每个TB的NDI,所述i为(5-M),换而言之,所述第i个比特为所述除3个连续比特之外的5个连续比特中,从第一个高位比特到低位比特第一个状态为1的比特,这样,终端设备在接收到DCI后,从DCI中的8个比特中除3个连续比特之外的5个连续比特中,确定第一个状态为1的比特在该5个比特的位置,即第i个比特,进而可以确定出M的取值为(5-i)。其中,从第一个高位比特到低位比特,请参见表3.2,所述3个连续比特可以位于所述5个连续比特的前面,或所述3个连续比特可以位于所述5个连续比特的后面,比如,3个连续比特设置为“000”用于指示第一TB对应的HARQ进程号为0,M=2时,DCI中的8个比特可以设置为“000001**”,或设置为“001**000”。
在情况2中,3个连续比特用于指示第一TB对应的HARQ进程号,虽然受限于预先定义的M个TB对应的M个HARQ进程号的排列方式,该8个比特不能指示任意HARQ进程号的组合,比如,若预先定义M个TB对应的HARQ进程号偶数排列,在M=2,第一TB对应的HARQ进程号为0时,该情况2所描述的方式不能指示0、1,或0、3,或0、4,或0、5等的调度方式,但是第一TB对应的HARQ进程号不是固定的,也就是说,第一TB对应的HARQ进程可以灵活指示,比如预先约定M个TB对应的HARQ进程号连续排列,第一TB为第一个TB,M=3时,第一个TB对应的HARQ进程号可以是0~5中的任一个,DCI调度3个TB的情况为6种,可见,情况3所描述的实施方式保障了DCI调度对多个TB调度的灵活性,同时,对DCI的比特开销也较少。
情况3:DCI能够调度的最多的TB个数为8,HARQ进程号的取值范围为[0,7]时,采用上述方式三指示调度的M个TB,1≤M≤8,这样需要占用DCI的10个比特,根据上述方式三,DCI包含10个比特,所述10个比特中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述10个比特中除所述M个比特之外的(9-M)个连续比特中有一个比特的状态为1且其他的(8-M)个比特的状态都为0,所述10个比特中除所述M个连续比特和所述(9-M)个连续比特外的一个比特的状态为1。
进一步地,所述(9-M)个连续比特中,从第一个高位比特到低位比特的第j个比特用于指示所述第一个TB对应的HARQ进程号(j-1),所述第j个比特的状态为1,所述其他的(8-M)个比特的状态都为0,所述10个比特中,从第一个高位比特到低位比特的第i个比特用于指示所述M的取值,所述第i个比特的状态为1,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个TB的NDI。
对于情况3,网络设备根据M、第一TB对应的HARQ进程号以及M个TB中的每个TB的NDI,按照上述方式三,将DCI中的10个比特中,从第一个高位比特到低位比特的(9-M)个比特用于指示第一TB对应的HARQ进程号,1个状态为1的比特用于指示M的取值,M个比特按照比特映射的方式指示M个TB中的每个TB的NDI。
具体实现过程如下,假设第一TB对应的HARQ进程号为(j-1),将DCI中的(5-M)个连续比特中,从第一个高位比特到低位比特的第j个比特的状态置1,在该(5-M)个中除该第j个比特以外的其余比特的状态置0,换而言之,该第j个比特为该DCI中的6个连续比特中从第一个高位比特到低位比特第一个状态为1的比特,比如M=2,j=1,DCI 的6个连续比特中的前3个连续比特用于指示(j-1)的取值,需要将该3个连续比特中的第二个比特的状态置为1,该3个连续比特中的第一个比特以及第3个比特的状态皆为0,这样,终端设备在接收到DCI后,可以从第一个高位比特到低位比特,确定第一个状态为1的比特在所述6个比特中的位置,即确定第j个比特,进而确定DCI调度的第一TB对应的HARQ进程号为(j-1);将DCI中的6个比特中,从第一个高位比特到低位比特的第i个比特的状态置为1,所述i取值为(6-M),由于前面的(5-M)个比特中仅第j个比特的状态为1,故该第i个比特为该DCI中的6个连续比特中从第一个高位比特到低位比特第二个状态为1的比特,比如M=2,需要将该6个连续比特中从第一个高位比特到低位比特的第4个比特的状态置为1,这样,终端设备在接收到DCI后,可以从第一个高位比特到低位比特,确定第二个状态为1的比特在所述6个连续比特中的位置,即确定第i个比特,进而确定M的取值为(6-i);将DCI中的6个比特中,从第一个高位比特到低位比特的第i个比特之后的M个连续比特按照比特映射的方式指示M个TB中的每个TB的NDI。
在情况3中,(9-M)个连续比特用于指示第一TB对应的HARQ进程号,虽然受限于预先定义的M个TB对应的M个HARQ进程号的排列方式,该(9-M)个连续比特不能指示任意HARQ进程号的组合,但是第一TB对应的HARQ进程号不是固定的,也就是说,第一TB对应的HARQ进程可以灵活指示,可见,情况3所描述的实施方式保障了DCI对多个TB调度的灵活性,同时,对DCI的比特开销也较少。
情况4:DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,3]时,采用上述方式三指示调度的M个TB,1≤M≤4,这样需要占用6个比特,根据上述方式三,DCI包含6个比特,所述6个比特中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述6个比特中除所述M个比特之外的(5-M)个连续比特中有一个比特的状态为1且其他的(4-M)个比特的状态都为0,所述6个比特中除所述M个连续比特和所述(5-M)个连续比特外的一个比特的状态为1。
进一步地,所述(5-M)个连续比特中,从第一个高位比特到低位比特的第j个比特用于指示所述第一个TB对应的HARQ进程号(j-1),所述第j个比特的状态为1,所述其他的(4-M)个比特的状态都为0,所述6个比特中,从第一个高位比特到低位比特的第i个比特用于指示所述M的取值,所述第i个比特的状态为1,所述第i个比特之后的M个连续比特按照比特映射的方式指示所述M个TB的NDI。
对于情况4,网络设备根据M、第一TB对应的HARQ进程号以及M个TB中的每个TB的NDI,按照上述方式三,将DCI中的6个比特中,从第一个高位比特到低位比特的连续(5-M)个比特用于指示第一TB对应的HARQ进程号,1个状态为1的比特用于指示M的取值,M个比特指示M个TB中的每个TB的NDI。
具体实现过程可参考上述对于情况3的具体实现过程,两者皆是按照上述方式三来调度M个TB,在此不再赘述。
请参见表7,示例性地示出了上述情况4对应的一种指示方式,其中,第一TB为第一个TB;如表7所示,M=4,第一TB对应的HARQ进程号为0时,网络设备将DCI中的6个连续比特设置为“11****”来调度4个TB;M=3,第一TB对应的HARQ进程号为0时,网络设备将DCI中的6个连续比特设置为“101***”来调度3个TB;M=3,第一TB对应的HARQ进程号为1时,网络设备将DCI中的6个连续比特设置为“011***” 来调度3个TB;M=2,第一TB对应的HARQ进程号为0时,网络设备将DCI中的6个连续比特设置为“1001**”来调度2个TB;M=2,第一TB对应的HARQ进程号为1时,网络设备将DCI中的6个连续比特设置为“0101**”来调度2个TB;M=2,第一TB对应的HARQ进程号为2时,网络设备将DCI中的6个连续比特设置为“0011**”来调度2个TB;M=1,第一TB对应的HARQ进程号为0时,网络设备将DCI中的6个连续比特设置为“10001*”来调度1个TB;M=1,第一TB对应的HARQ进程号为1时,网络设备将DCI中的6个连续比特设置为“01001*”来调度1个TB;M=1,第一TB对应的HARQ进程号为2时,网络设备将DCI中的6个连续比特设置为“00101*”来调度1个TB;M=1,第一TB对应的HARQ进程号为3时,网络设备将DCI中的6个连续比特设置为“00011*”来调度1个TB。
表7:一种指示方式
在情况4中,(5-M)个连续比特用于指示第一TB对应的HARQ进程号,虽然受限于预先定义的M个TB对应的M个HARQ进程号的排列方式,该(5-M)个连续比特不能指示任意HARQ进程号的组合,比如,若预先定义M个TB对应的HARQ进程号连续排列,在M=2,第一TB对应的HARQ进程号为0时,该情况2所描述的方式不能指示0、2,或0、3的调度方式,但是第一TB对应的HARQ进程号不是固定的,也就是说,第一TB对应的HARQ进程可以灵活指示,比如,第一TB为第一个TB,M=2时,第一个TB对应的HARQ进程号可以是0~2中的任一个,DCI调度2个TB的情况为3种,可见,情况2所描述的实施方式保障了DCI调度对多个TB调度的灵活性,同时,对DCI的比特开销也较少。
情况5:预先定义第一个TB对应的HARQ进程号为0,DCI能够调度的最多的TB个数为8,HARQ进程号的取值范围为[0,7]时,采用上述方式四指示调度的M个TB,根据上述方式四,DCI包含9个连续比特,所述9个连续比特中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述9个连续比特中除所述M个连续比特之外的(9-M)个比特指示M的取值。
进一步地,所述(9-M)个连续比特中,从第一个高位比特到低位比特的第i个比特的状态为1,所述第i个比特之前的比特的状态为0,该i为(9-M),M的取值为(9-i)。
对于情况5,网络设备根据M以及M个TB中的每个TB的NDI,按照上述方式四,将DCI中的9个连续比特中,从第一个高位比特到低位比特的第i个比特的状态置为1,所述第i个比特之前的比特的状态置为0,所述第i个比特之后的M个连续比特按照比特映射的方式指示M个TB中的每个TB的NDI,所述i为(9-M),换而言之,所述第i个比特为所述9个比特中,从第一个高位比特到低位比特第一个状态为1的比特,这样,终端设备可以根据所述9个比特中,确定从第一个高位比特到低位比特的第一个状态为1的比特在所述9个比特的位置,即第i个比特,进而确定M的取值为(9-i)。
在情况5中,尽管第一TB对应的HARQ进程号为固定值,DCI对多个TB调度的灵活性较低,但DCI的比特开销最小,若对DCI的比特开销较为敏感的话,可以选择情况5所对应的实施方式来调度多个TB,以最大程度降低对DCI的比特开销。
当然,网络设备向终端设备指示DCI调度的一个或多个TB对应的HARQ进程号不限于如上的五种情况,比如还可以包括DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,3]时,可以按照上述方式二来调度M个TB,即DCI的比特开销为7个比特,该7个比特中的2个连续比特用于指示第一TB对应的HARQ进程号。
在S33中,即在HARQ进程号的取值范围内,终端设备确定所述下行控制信息调度的一个或多个传输块对应的HARQ进程号。由于网络设备可以优选情况1、情况2、情况3、情况4、以及情况5中的至少一个方式向终端设备指示DCI调度的M个TB,故终端设备需要根据网络设备所指示的信息确定M个TB。下面就情况1、情况2、情况3、情况4、以及情况5为例,详细介绍终端设备如何确定DCI调度DCI调度的M个TB。
对于情况1:DCI能够调度的最多的TB个数为2,HARQ进程号的取值范围为[0,3]时,可以由前述方式一指示调度的M个TB,这样需要占用DCI中的5个比特,根据前述方式一,DCI包括第一字段,所述第一字段用于确定所述一个或者两个TB中每个TB对应的HARQ进程号,且当所述第一字段指示两个TB对应的HARQ进程号时,所述两个TB对应的HARQ进程号能够是不连续的,且所述DCI还按照比特映射的方式指示每个TB的NDI。
进一步地,该第一字段的3个连续比特指示了6种状态中的一种时,确定所述DCI调度了2个TB,该3个连续比特指示的两个TB中每个TB对应的HARQ进程号,以及所述2个连续比特指示的所述2个TB的NDI。
进一步地,该3个连续比特指示了除所述6中状态外剩余的2种状态中的一种,确定所述DCI调度了1个TB,所述3个连续比特指示的一个TB对应的HARQ进程号,以及所述2个连续比特中,从第一个高位比特到低位比特的第一个比特指示的所述一个TB的NDI。
具体地,终端设备可以按照前述方式一确定DCI调度M个TB,即DCI中的5个比特用于指示M个TB,该5个比特中的3个连续比特用于指示的M个TB中每个TB对应的HARQ进程号,该5个比特中除该3个连续比特之外的比特用于指示M个TB中每个TB的NDI,比如,请参见表2.2,DCI中用于指示M个TB的5个比特为“011**”,终端设备可以确定出该DCI调度的M个TB对应的HARQ进程号分别为1、2,隐式指示了M的取值为2,则该3个连续比特之后的2个比特用于指示每个TB的NDI。
对于情况2:DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,7]时,由前述方式二指示调度的M个TB,1≤M≤4,这样需要占用DCI中的8个比特,根据前述方式二,所述DCI指示了所述M个TB中的第一个TB对应的HARQ进程号,所述M个TB对应的M个HARQ进程号是连续的,所述DCI包括有5个连续比特的第二字段,所述第二字段中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述第二字段中其余(5-M)个比特中有(4-M)个比特的比特状态都是0且除所述(4-M)比特之外的一个比特的比特状态是1。

具体地,终端设备可以按照前述方式二确定DCI调度M个TB,即DCI中的8个比特用于指示M个TB,该8个比特中的3个连续比特用于指示第一TB对应的HARQ进程号,除该3个连续比特之外的5个连续比特中,从第一个高位比特到低位比特的第一个状态为1的比特在该5个连续比特中的位置指示M的取值,该第一个状态为1的比特为第i个比特,该第i个比特之前的比特状态为0,该第i个比特之后的比特用于指示M个TB中的每个TB的NDI。终端设备仅需确定出该8个比特中从第一个高位比特到低位比特的3个连续比特来确定第一TB对应的HARQ进程号,除该3个连续比特之外的5个比特中的第一个状态为1的比特在该5个比特中的位置,即第i个比特,可确定出M的取值为(5-i)。
进步一地,终端设备根据第一TB对应的HARQ进程号以及M,确定除该第一TB之外的其余(M-1)个TB对应的HARQ进程号,以及根据该第i个比特之后的(4-i)个比特来确定M个TB中每个TB的NDI。
对于情况3:DCI能够调度的最多的TB个数为8,HARQ进程号的取值范围为[0,7]时,由前述方式三指示调度的M个TB,1≤M≤8,这样需要占用DCI的10个比特,根据前述方式三,DCI包含10个比特,所述10个比特中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,所述10个比特中除所述M个比特之外的(9-M)个连续比特中有一个比特的状态为1且其他的(8-M)个比特的状态都为0,所述10个比特中除所述M个连续比特和所述(9-M)个连续比特外的一个比特的状态为1。
进一步地,所述(9-M)个连续比特中,从第一个高位比特到低位比特的第一个比特状态为1的比特为第j个比特,所述10个比特中,从第一个高位比特到底位比特的第二个比特状态为1的比特为第i个比特,确定所述第一个TB对应的HARQ进程号为(j-1),所述M的取值为(10-i),所述M个TB中除了所述第一个TB之外剩余(M-1)个TB对应的HARQ进程号,以及所述M个连续比特指示的所述M个TB的NDI。
具体地,终端设备可以按照前述方式三确定DCI调度M个TB,即DCI中的10个比特用于指示M个TB,该10个比特中,从第一个高位比特到低位比特的第一个状态为1的比特在所述10个比特中的位置用于指示第一TB对应的HARQ进程号,第二个状态为1的比特在所述10个比特中的位置用于指示M的取值,所述第二个状态为1的比特之后的比特用于指示M个TB中每个TB的NDI;终端设备仅需确定出该10个比特中从第一个高位比特到低位比特的第j个比特的状态为1,则可确定出第一TB对应的HARQ进程号为(j-1),以及确定该10个比特中从第一个高位比特到低位比特的第二个状态为1的比特,即 第i个比特,可确定出M的取值为(10-i)。
进步一地,终端设备根据第一TB对应的HARQ进程号以及M,确定除该第一TB之外的其余(M-1)个TB对应的HARQ进程号,以及根据该第i个比特之后的(10-i)个连续比特来确定M个TB中每个TB的NDI。
对于情况4:DCI能够调度的最多的TB个数为4,HARQ进程号的取值范围为[0,3]时,由前述方式三指示调度的M个TB,1≤M≤4,这样需要占用6个比特,根据上述方式三,DCI包含6个比特,6个比特中有M个连续比特按照比特映射的方式指示所述M个TB的NDI,6个比特中除所述M个比特之外的(5-M)个连续比特中有一个比特的状态为1且其他的(4-M)个比特的状态都为0,所述6个比特中除所述M个连续比特和所述(5-M)个连续比特外的一个比特的状态为1。
进一步地,该(5-M)个连续比特中从第一个高位比特到低位比特的第一个比特状态为1的比特为第j个比特,所述6个比特中从第一个高位比特到低位比特的第二个比特状态为1的比特为第i个比特,确定所述第一个TB对应的HARQ进程号为(j-1),所述M的取值为(6-i),所述M个TB中除了所述第一个TB之外剩余(M-1)个TB对应的HARQ进程号,以及所述M个连续比特指示的所述M个TB的NDI。
