Description

通信方法和通信装置
本申请要求申请日2021年09月30日递交中国国家知识产权局的，申请号为CN202111160969.1的中国专利申请的优先权，其通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种通信方法和通信装置。
背景技术
目前，在配置授权物理上行共享信道(physical uplink shared channel，PUSCH)的传输中，一个时隙承载一个PUSCH重复，一个时隙承载一个传输块循环冗余校验码。在一个传输周期内，配置授权物理PUSCH可以从冗余版本(redundancy version，RV)为0的重复所在的时隙开始PUSCH传输，这种情况下，网络设备在接收PUSCH时，需要判断终端设备从哪个RV为0的重复所在的时隙开始发送。
为了增强上行覆盖，可以考虑在多个时隙上承载一个PUSCH重复，在多个时隙上承载一个传输块循环冗余校验码。在这种新的传输方式下，在考虑资源利用效率和网络侧设备的盲检复杂度的情况下，如何确定PUSCH传输的初始时隙，如何设定每个PUSCH重复的RV，成为了新的PUSCH传输方式应用于配置授权资源需要解决的问题。

在NR中，一般有以下几种物理上行共享信道(physical uplink shared channel，PUSCH)的调度方式。
方式一：
用一个下行控制信息(downlink control information，DCI)中的上行授权动态调度PUSCH，其中，DCI为物理层信息。
这种情况下，终端设备接收到一次上行调度，就进行一次PUSCH传输。
方式二：
配置授权(configured grant，CG)类型1：由包含rrc-ConfiguredUplinkGrant的高层信息单元configuredGrantConfig半持续配置，不需要接收DCI中的上行授权。
这种情况下，高层配置了一些半持续资源，终端设备如果有上行数据需要发送，就可以使用这些资源进行PUSCH发送，如果没有上行数据需要发送，就不发送。
方式三：
配置授权类型2：先接收不包含rrc-ConfiguredUplinkGrant的高层信息单元configuredGrantConfig，再由有效激活DCI中的上行授权半持续调度。
这种情况下，高层配置了一些半持续资源，然后由物理层信令去激活，激活时终端设备如果有上行数据需要发送，就可以使用这些资源进行PUSCH发送，如果没有激活，这些资源是不能使用的。
一次PUSCH可以包含多个重复(repetition)，每个重复都传输相同的传输块(transport block，TB)，冗余版本可以相同或不同，一个重复中承载一个传输块循环冗余校验码(transport block cyclic redundancy check，TB CRC)，另外速率匹配的单位也是一个重复。本申请的技术方案将针对多时隙传输块PUSCH传输。
图2是本申请实施例中的一种重复类型的示意图。
如图2中的(a)所示，设有k个重复(k＝4)，则k次传输机会对应连续的k个时隙(slot)，每个时隙中的一个传输机会可以用来传输一个PUSCH的重复，每个传输机会(图2中的图案填充部分)在每个时隙中的起始符号和持续时间相同。
在时分复用(time-division duplexing，TDD)模式下，如果一次PUSCH重复的资源中的任一个符号是下行符号，或者PUSCH时频资源和取消指示(cancellation indication，CI)指示取消的资源有重叠，或者和高优先级的上行信道/信号传输重叠，则此次PUSCH重复取消发送，如图2中的(b)所示，在第二个重复中，重复的资源A为下行符号，则该第二个PUSCH重复取消发送。
然而，在一些情况下，可能存在来不及取消发送的情形，如图2中的(c)所示，当第二个PUSCH重复已经开始发送了，如在to时刻才解析出CI，发现有资源B重叠，此时，该第二PUSCH重复已经传输了部分，则只能取消部分PUSCH重复。
从上述内容可知，其重复类型中，一次PUSCH传输的K次重复是标称重复，也就是说一次PUSCH传输对应k个时隙，无论这k个时隙中的每个时隙是否可以真正用来发送PUSCH重复。
那么，在另一种重复类型中，引入了有效时隙(available slot)的概念。对于上述方式一中的PUSCH的调度方式，可以基于无线资源控制(radio resource control，RRC)配置和调度DCI确定K个有效时隙。对于上述方式二中的PUSCH的调度方式，可以基于RRC配置确定K个有效时隙。对上述方式三中的PUSCH的调度方式，可以基于RRC配置和激活DCI确定K个有效时隙。
前文中提到，一些原因会导致一次PUSCH发送的某个重复取消。一类是根据RRC配置确定的，第二类是根据动态指示确定的，即物理层指示导致的，例如CI。而有效时隙的确定可以只考虑RRC信令，而不考虑此次PUSCH调度DCI以外的其它物理层指示。
图3是本申请实施例中的另一种重复类型的示意图。如图3中的(a)所示，在第二个重复的时隙中存在一个RRC配置的高优先级上行信道/信号传输和本PUSCH资源重叠，则该时隙不是一个有效时隙。
如图3中的(b)所示，在第二个重复的时隙中存在一个物理层指示的高优先级上行信道/信号传输和本PUSCH资源重叠，那么该时隙仍然是一个有效时隙。
在多时隙传输块PUSCH传输中，设有K个重复，则每个重复对应N个连续的时隙，K个传输机会共对应N*K个连续的时隙，每个时隙内的可用资源的起始符号和持续时间相同。一个重复中承载一个TB CRC，即N个时隙上至承载一个TB CRC，从而可以降低TB CRC的信令开销。
另外，速率匹配也可以以N个时隙为单位进行。需要注意的是，这里的时隙可以是所有时隙，也可以是有效时隙。
图4是本申请实施例中的多时隙传输块的示意图。如图4所示，设有k个重复(k＝2)，每个重复中可以理解为一个多时隙传输块，每个重复中包括4个有效时隙。
图5是本申请实施例中的时域资源配置的示意图。如图5所示，在配置授权PUSCH传输中，高层配置资源可以包含以下参数：
周期(periodicity)：即表示相邻两组传输机会之间的间距，periodicity的取值最小是2个符号，最大可以是5120个时隙。
重复次数repK：即每组传输机会中包含的传输机会的个数，也就是重复次数，还可以是时隙数或有效时隙数。
应理解，repK可以简称为K，K的取值可以包括{1，2，4，8}，未来可能支持的取值可以包括{1，2，3，4，7，8，12，16，20，24，28，32}，K还可以取其他值，本申请实施例对此不予限定。
高层参数repK-RV指示K次重复传输中采用的冗余版本(redundancy version，RV)序列，针对K次传输中的第n次传输机会，采用RV序列中的第(mod(n-1,4)+1)个值，n＝1，2，…，K。
repK-RV存在四种情况，分别为不配置、配置为{0，2，3，1}、配置为{0，3，0，3}、配置为{0，0，0，0}。
如果高层参数startingFromRV0配置为“off”，则一个传输块只能从K个重复的第一个传输机会开始传输，否则，一个传输块按下述描述传输：
当K＝1时，ConfiguredGrantConfig不配置参数repK-RV，传输的RV版本设为0。
下面将结合图6-图8分别介绍余下的几种RV序列下的传输块的传输方式。
如果RV序列配置为{0，2，3，1}，则初始传输只能在K次重复的第一个传输机会上，如图6所示，图6是本申请实施例中的一种冗余版本序列的示意图。
当K＝2时，第一个重复中使用的RV为0，第二个重复中使用的RV为3。
应理解，若每个重复中包含N个时隙，则该N个时隙使用的RV均相同。
当K＝4时，第一个重复中使用的RV为0，第二个重复中使用的RV为3，第三个重复中使用的RV为3，第四个重复中使用的RV为1。
应理解，若每个重复中包含N个时隙，则该N个时隙使用的RV均相同。
当K＝8时，第一个重复中使用的RV为0，第二个重复中使用的RV为3，第三个重复中使用的RV为2，第四个重复中使用的RV为1，第五个重复中使用的RV为0，第六个重复中使用的RV为3，第七个重复中使用的RV为2，第 八个重复中使用的RV为1。
应理解，若每个重复中包含N个时隙，则该N个时隙使用的RV均相同。
还应理解，当K为其他值时，如K＝16，则该16个重复可以按照RV序列{0，2，3，1}循环使用。
如果RV序列配置为{0，3，0，3}，则初始传输可以发生在K次重复的传输机会中的任意一个对应RV＝0的传输机会上，如图7所示，图7是本申请实施例中的另一种冗余版本序列的示意图。
当K＝2时，第一个重复中使用的RV为0，第二重复使用的RV为3。
应理解，若每个重复中包含N个时隙，则该N个时隙使用的RV均相同。
当K＝4时，重复的传输情况可能包括以下两种：
一种是初始传输从第一个重复开始，则第一重复使用的RV为0，第二个重复使用的RV为3，第三个重复使用的RV为0，第四个重复使用的RV为3。
另一种是第一个重复和第二个重复不传输PUSCH，初始传输从第三个重复开始，则第三个重复使用的RV为0，第四个重复使用的RV为3。
当K＝8时，重复的传输情况可能包括以下四种：
第一种是初始传输从第一个重复开始，则第一个重复中使用的RV为0，第二个重复中使用的RV为3，第三个重复中使用的RV为0，第四个重复中使用的RV为3，第五个重复中使用的RV为0，第六个重复中使用的RV为3，第七个重复中使用的RV为0，第八个重复中使用的RV为3。
第二种是第一个重复和第二个重复不传输PUSCH，初始传输从第三个重复开始，则第三个重复使用的RV为0，第四个重复使用的RV为3，第五个重复中使用的RV为0，第六个重复中使用的RV为3，第七个重复中使用的RV为0，第八个重复中使用的RV为3。
第三种是第一个重复至第四个重复不传输PUSCH，初始传输从第五个重复开始，则第五个重复中使用的RV为0，第六个重复中使用的RV为3，第七个重复中使用的RV为0，第八个重复中使用的RV为3。
第四种是第一个重复至第六个重复不传输PUSCH，初始传输从第七个重复开始，第七个重复中使用的RV为0，第八个重复中使用的RV为3。
如果RV序列配置为{0，0，0，0}，则初始传输可以发生在K次重复的传输机会的任意一个传输机会上；但是当K＝8时，初始传输不能发生在最后一个传输机会上。如图8所示，图8是本申请实施例中的另一种冗余版本序列的示意图。
当K＝2时，重复的传输情况可能包括以下两种：
一种是初始传输从第一个重复开始，则第一个重复使用的RV为0，第二重复使用的RV为0。
另一种是第一个重复不传输PUSCH，则第二个重复使用的RV为0。
当K＝4时，重复的传输情况可能包括以下四种：
第一种是初始传输从第一个重复开始，则第一个重复至第四个重复使用的RV均为0。
第二种是第一个重复不传输PUSCH，初始传输从第二个重复开始，则第二个重复至第四个重复使用的RV均为0。
第三种是第一个重复、第二个重复不传输PUSCH，初始传输从第三个重复开始，则第三个重复至第四个重复使用的RV均为0。
第四种是第一个重复至第三个重复不传输PUSCH，初始传输从第四个重复开始，则第四个重复使用的RV均为0。
当K＝8时，重复的传输情况可能包括以下七种：
第一种是初始传输从第一个重复开始，则第一个重复至第八个重复使用的RV均为0。
第二种是第一个重复不传输PUSCH，初始传输从第二个重复开始，则第二个重复至第八个重复使用的RV均为0。
第三种是第一个重复、第二个重复不传输PUSCH，初始传输从第三个重复开始，则第三个重复至第八个重复使用的RV均为0。
第四种是第一个重复至第三个重复不传输PUSCH，初始传输从第四个重复开始，则第四个重复至第八个重复使用的RV均为0。
第五种是第一个重复至第四个重复不传输PUSCH，初始传输从第五个重复开始，则第五个重复至第八个重复使用的RV均为0。
第六种是第一个重复至第五个重复不传输PUSCH，初始传输从第六个重复开始，则第六个重复至第八个重复使用的RV均为0。
第七种是第一个重复至第六个重复不传输PUSCH，初始传输从第七个重复开始，则第七个重复至第八个重复使用的RV均为0。
针对任意一种RV序列，重复传输的停止条件有三种，哪一种先达到都要停止传输：
(1)已经传输了K次。
(2)在周期periodicity内的K次重复的最后一个传输机会进行传输。
(3)在用DCI format0_0或0_1调度的相同进程的另一个PUSCH的起始符号上。
如前文所述，在一个传输机会上，如果终端设备有数据需要发送，就可以在配置的资源上发送；如果终端设备没有数据需要发送，就可以不发送。终端设备是否发送了数据，网络设备需要进行盲检。网络设备可以给不同的终端设备进行不同的解调参考信号(demodulation reference signal，DMRS)参数配置，这样，网络设备可以监测不同终端设备的不同DMRS，检测终端设备在此次传输机会上，是否有数据发送。
此外，在一个传输机会上，配置授权PUSCH可以从RV为0的重复开始PUSCH传输，这种情况下，网络设备在接收PUSCH时，需要判断终端设备从哪个RV为0的重复中开始发送的，从而增加了网络设备进行盲检的复杂度。
进一步地，网络设备采用DMRS判断传输机会上是否有数据发送，还可能会造成在一个传输机会上没有PUSCH发送，盲检的结果为有PUSCH发送；或 者，在一个传输机会上有PUSCH发送时，盲检的结果为没有PUSCH发送，从而导致PUSCH接收性能下降。
为了增强上行覆盖，可以考虑在多个时隙上承载一个PUSCH重复，在多个时隙上承载一个传输块循环冗余校验码。在这种新的传输方式下，在考虑资源利用效率和网络侧设备的盲检复杂度的情况下，如何确定PUSCH传输的初始时隙，如何设定每个PUSCH重复的RV，成为了新的PUSCH传输方式应用于配置授权资源需要解决的问题。
有鉴于此，本申请实施例提供一种通信方法，以期降低网络设备进行盲检的复杂度，并提升PUSCH的接收性能。
图9是本申请实施例提供的一种通信方法的示意性交互图。如图9所示，该方法可以包括步骤910至步骤940。
910，网络设备向终端设备发送第一参数和第二参数，其中，所述第一参数和所述第二参数为如下参数中的任意两个：一个配置授权周期内的有效时隙数P；一个配置授权周期内的重复数量K；每个重复的有效时隙数N，N为大于或等于2的整数，所述每个重复中承载一个传输块循环冗余校验码TB CRC。
需要说明的是，全文中的有效时隙可以替换为时隙，也就是不区分是否有效。
需要说明的是，每个重复的有效时隙数为N是指每个重复在N个有效时隙上传输。
示例性地，该第一参数为一个配置授权周期内的有效时隙数P，该第二参数为一个配置授权周期内的重复数量K；或者，该第一参数为一个配置授权周期内的有效时隙数P，该第二参数为每个重复的有效时隙数N；或者，该第一参数为一个配置授权周期内的有效时隙数P，该第二参数为每个重复的有效时隙数N。
应理解，该第一参数和第二参数可以承载在无线资源控制RRC信令中；或者，第一参数和第二参数承载在激活下行控制信息DCI中；或者，第一参数承载在RRC信令中，第二参数承载在激活DCI中；或者，第一参数承载在激活DCI中，第二参数承载在RRC信令中，本申请实施例对此不予限定。当第一参数和第二参数分别承载在RRC信令和激活DCI中时，网络设备可以根据实时传输情况进行参数调整，从而可以增加网络设备调度的灵活性，进一步地，也可以减少物理层的信令开销。
需要说明的是，这里的激活下行控制信息DCI是指配置授权类型2的PUSCH传输的激活下行控制信息。
在一些实现方式中，当所述第一参数为所述一个配置授权周期内的有效时隙数P时，若所述第二参数为所述重复数量K，则所述一个配置授权周期内的有效时隙数P为所述重复数量K的整数倍；
若所述第二参数为所述每个重复中的有效时隙数N，则所述一个配置授权周期内的有效时隙数P为所述每个重复中的有效时隙数N的整数倍。
当一个配置授权周期内的有效时隙数P为一个配置授权周期内的重复的数量K或每个重复包括的有效时隙数N的整数倍时，有利于减小计算初始时隙的 复杂度。
这种情况下，协议可以规定一个配置授权周期内的有效时隙数P为一个配置授权周期内的重复的数量K或每个重复包括的有效时隙数N的整数倍，当该一个配置授权周期内的有效时隙数P不为一个配置授权周期内的重复的数量K或每个重复包括的有效时隙数N的整数倍时，终端设备可以认为是无效配置。
在另一些实现方式中，当所述第一参数和所述第二参数为所述重复数量K和所述每个重复中的有效时隙数N时，则所述一个配置授权周期内的有效时隙数为K*N。
在这种情况下，一个配置授权周期内的有效时隙数P可以通过第一参数和第二参数计算得到，即P＝K*N。
920，终端设备根据所述第一参数和所述第二参数确定配置授权PUSCH传输的初始时隙。
应理解，该初始时隙指的是终端设备开始传输PUSCH的时隙。该初始时隙可以是一个配置授权周期内的有效时隙中的第一个，也可以是一个配置授权周期内的有效时隙中的最后一个，还可以是一个配置授权周期内的有效时隙的其他时隙，本申请实施例对此不予限定。
在一种可能的实现方式中，所述初始时隙为一个配置授权周期内与参考有效时隙距离M*N1个有效时隙的有效时隙，M为整数，当第一参数或第二参数为每个重复的有效时隙数N时，N1＝N，当第一参数和第二参数中一个是一个配置授权周期内的有效时隙数P，另一个是一个配置授权周期内的重复的数量K时，N1＝floor(P/K)或者N1＝ceiling(P/K)；或者，所述初始时隙为一个配置授权周期内与参考有效时隙距离M*N1-1个有效时隙的有效时隙，其中，M为大于或等于1的整数，当第一参数或第二参数为每个重复的有效时隙数N时，N1＝N，当第一参数和第二参数中一个是一个配置授权周期内的有效时隙数P，另一个是一个配置授权周期内的重复的数量K时，N1＝floor(P/K)或者N1＝ceiling(P/K)。
需要说明的是：初始时隙为与参考有效时隙距离M*N1个有效时隙是指有效时隙的序号相差M*N1个，可以是初始时隙的序号比参考有效时隙的序号大M*N1，也可以是参考有效时隙的序号比初始时隙的序号大M*N1。
其中，所述终端设备根据所述第一参数和所述第二参数确定配置授权物理上行共享信道PUSCH传输的初始时隙，包括：
所述终端设备根据冗余版本RV序列和所述第一参数和所述第二参数确定配置授权物理上行共享信道PUSCH传输的初始时隙，所述冗余版本RV序列是所述终端设备从所述网络设备接收的。
应理解，终端设备可以根据第一参数、第二参数确定初始时隙，并根据RV序列确定该初始时隙承载的重复使用的RV。
应理解，该RV序列可以是终端设备从网络设备接收的。该RV序列可以是前文中的{0，0，0，0}、{0，2，3，1}、{0，3，0，3}等。
930，终端设备根据所述初始时隙，进行所述配置授权PUSCH传输。
其中，终端设备根据所述初始时隙，从该初始时隙开始，进行配置授权PUSCH传输。
具体地，该终端设备从该初始时隙上承载的重复开始，根据所述配置授权PUSCH传输的每个重复的RV进行所述配置授权PUSCH的编码；并根据编码的结果进行配置授权PUSCH的传输。
可选地，所述初始时隙上承载的重复的RV为0。
示例性地，参见图10中的(a)，图10是本申请实施例提供的一种传输PUSCH的可能性的示意图。一个配置授权周期内的重复数量K为2，每个重复中包括的有效时隙数N为4，则一个配置授权周期内的有效时隙P＝K*N＝8，RV序列为{0，3，0，3}。
在可能性A中，初始时隙为配置授权周期内的有效时隙中的第一个，则第一个重复即第一个时隙至第四个时隙编码使用的RV为0，第二个重复即第五个时隙至第八个时隙编码使用的RV为3，则终端设备可以对编码后的重复进行配置授权PUSCH传输。
在可能性B中，初始时隙为配置授权周期内的有效时隙中的第五个，即不在第一个重复传输PUSCH，第五个时隙至第八个时隙编码使用的RV为0，则终端设备可以对编码后的第二个重复进行配置授权PUSCH传输。
可选地，一个重复使用一个RV，所述配置授权PUSCH传输的所有重复循环使用所述RV序列中的RV。
示例性地，参见图10中的(c)，一个配置授权周期内的有效时隙数P为16，每个重复包括的有效时隙的数量N为4，可知，该配置授权周期内的重复数量K为4，RV序列为{0，3，0，3}。
在可能性A中，初始时隙为配置授权周期内的有效时隙中的第一个，则第一个重复中包括的第一个有效时隙至第四个有效时隙使用的RV相同，即RV为0，第二个重复使用的RV为3，第三个重复使用的RV为0，第四个重复使用的RV为3。应理解，若该配置授权周期拥有更多个重复，则余下的重复可以根据该RV序列循环使用RV。
940，网络设备进行盲检。
应理解，网络设备在进行盲检时，可以从多种可能的初始时隙开始，采用DMRS判断一个配置授权调度上是否有数据发送。当确定在一种可能的初始时隙上有数据发送时，可以根据RV序列对初始时隙上承载的重复进行译码。
示例性地，当一个初始时隙上有数据发送时，且网络设备确定初始时隙上承载的重复的RV为0，则可以直接用RV0进行译码。
其中，网络设备可以在接收到配置授权PUSCH后，可以确定PUSCH传输的初始时隙，从而可以减低网络设备盲检的复杂度。
基于本申请实施例，网络设备向终端设备发送第一参数和第二参数，终端设备可以根据该第一参数和第二参数确定配置授权PUSCH传输的初始时隙，并根据该初始时隙进行配置授权PUSCH传输，从而有利于降低网络设备盲检的复杂 度。

在一个示例中，参见图11中的(a)，图11是本申请实施例提供的另一种PUSCH传输的可能性的示意图，第一参数可以为一个配置授权周期内的有效时隙数P，P＝16，第二参数为每个重复中的有效时隙数N，N＝3，则P不为N的整数倍，所述参考有效时隙为所述一个配置授权周期内的有效时隙中的第一个，则所述初始时隙为一个配置授权周期内与参考有效时隙距离M*N个有效时隙的有效时隙。

在另一个示例中，参见图12中的(a)，图12是本申请实施例提供的另一种PUSCH传输的可能性的示意图，第一参数可以为一个配置授权周期内的有效时隙数P，P＝16，第二参数为每个重复中的有效时隙数N，N＝3，则P不为N的整数倍，所述参考有效时隙为所述一个配置授权周期内的有效时隙中的最后一个，即第16个有效时隙，所述初始时隙为一个配置授权周期内与参考有效时隙距离M*N-1个有效时隙的有效时隙，M为大于或等于1的整数。
当M＝1时，对应于可能性E，初始时隙为一个配置授权周期内与参考有效时隙距离1*3-1个有效时隙的有效时隙，即该初始时隙为第十四个有效时隙。

当M＝5时，对应于可能性A，初始时隙为一个配置授权周期内与参考有效时隙距离5*3-1个有效时隙的有效时隙，即该初始时隙为第二个有效时隙。
可选地，所述参考有效时隙为预设的；或者所述参考有效时隙是所述终端设 备从所述网络设备接收的。
应理解，该参考有效时隙为预设的，可以理解为该参考有效时隙为协议规定的。
可选地，所述M＝A1*N2，其中，A1为大于或等于0的整数，N2为所述RV的最小周期。
应理解，该N2为RV的最小周期，该最小周期指的是，RV序列中相邻两个相同RV的距离。示例性地，当RV序列为{0，0，0，0}时，该RV的最小周期为1，当RV序列为{0，3，0，3}，该RV的最小周期为2，当RV序列为{0，3，2，1}时，该RV的最小周期为4。
示例性地，参见图10中的(c)，该RV的序列为{0，3，0，3}，则该最小周期N2＝2，则该M＝A1*2，当A1＝0时，M＝0，则初始时隙为距离参考时隙0*4个有效时隙的有效时隙，即一个配置授权周期内的第一个有效时隙，对应于可能性A。

可选地，所述初始时隙上承载的重复的RV为0。
示例性地，参见图12中的(a)、(b)，初始时隙上承载的重复使用的RV为0。
该技术方案中，当初始时隙上承载的重复使用的RV为0时，由于RV0里基本包含了全部系统比特，如果从RV0开始发送，则可以提升提前译码成功的可能性。
可选地，所述初始时隙上承载的重复的RV为RV序列中的第T个RV，T＝floor(S/N)+1，S为初始时隙在一个配置授权周期内的有效时隙中的序号。
应理解，S可以从0开始，T可以从1开始。一个配置授权周期中的所有有效时隙从0开始标号，这里所说的所有有效时隙是指所有P个有效时隙或者所有N*K个有效时隙。
示例性地，参见图13，图13是本申请实施例提供的另一种PUSCH传输的可能性的示意图。一个配置授权周期内的有效时隙数P＝16，每个重复中包括的有效时隙数N＝4，则该一个配置授权周期内包括4个重复，该RV序列为{0，3，0，3}。
对于可能性A，该初始时隙为一个配置授权周期内的第一个有效时隙，则T＝floor(0/4)+1，则初始时隙所在的第一个重复的RV为RV序列中的第1个RV，即RV为0。
对于可能性B，该初始时隙在一个配置授权周期内的有效时隙中的序号为5， 则T＝floor(4/4)+1＝2，则初始时隙所在的第二个重复的RV为RV序列中的第2个RV，即RV为3。
同样的，当初始时隙在一个配置授权周期内的有效时隙中的序号为9时，该初始时隙所在的第三个重复的RV为RV序列中的第3个RV，即RV为0。
示例性地，参见图14，图14是是本申请实施例提供的另一种PUSCH传输的可能性的示意图。
对于图14中的(a)，参考有效时隙为一个配置授权周期内的有效时隙中的第一个，且一个配置授权周期内的有效时隙P(P＝16)不为一个重复中包括的有效时隙数N(N＝3)的整数倍，RV序列为{0，3，0，3}。
对于可能性A，该初始时隙为一个配置授权周期内的第一个有效时隙，即该初始时隙在一个配置授权周期内的有效时隙中的序号为0，则T＝floor(0/3)+1，则初始时隙对应的有效时隙所在的第一个重复的RV为RV序列中的第1个RV，即RV为0。
对于可能性B，该初始时隙在一个配置授权周期内的有效时隙中的序号为4，则T＝floor(3/3)+1＝2，则初始时隙对应的有效时隙所在的第一个重复的RV为RV序列中的第2个RV，即RV为3。
同样的，对于可能性C，该初始时隙所在的第三个重复的RV为RV序列中的第3个RV，即RV为0。对于可能性D，该初始时隙所在的第四个重复的RV为RV序列中的第4个RV，即RV为3。对于可能性E，该初始时隙所在的第五个重复的RV为RV序列中的第1个RV，即RV为0。
对于图14中的(b)，参考有效时隙为一个配置授权周期内的有效时隙中的最后一个，且一个配置授权周期内的有效时隙P(P＝16)不为一个重复中包括的有效时隙数N(N＝3)的整数倍，RV序列为{0，3，0，3}。
对于可能性A，该初始时隙为一个配置授权周期内的第一个有效时隙，即该初始时隙在一个配置授权周期内的有效时隙中的序号为1，则T＝floor(1/3)+1，则初始时隙所在的第一个重复的RV为RV序列中的第1个RV，即RV为0。
对于可能性B，该初始时隙在一个配置授权周期内的有效时隙中的序号为4，则T＝floor(4/3)+1，则初始时隙所在的第一个重复的RV为RV序列中的第2个RV，即RV为3。
同样的，对于可能性C、D、E，可以根据上述方式进行计算，为了简洁，不再赘述。
应理解，当P为其他值，如P为20、24、28、32或其他值时，本申请实施例中的技术方案同样是适用的，具体可以参见上述的相关描述，为了简洁，不再赘述。
该技术方案可以根据初始时隙的位置来确定初始时隙所在的重复的RV，从而简化了终端设备传输PUSCH的复杂度。
可选地，在所述初始时隙上承载的重复的RV不为0的情况下，所述配置授权PUSCH传输的所有重复中至少存在一个重复使用的RV为0。
示例性地，参见图13，不存在可能性D的情况。
RV0中基本包含全部系统比特，而除RV0以外其他的RV中可能只包括部分系统比特，如果仅发送其他的RV，可能导致无法译码。该技术方案可以提升提前译码的可能性。
此外，当初始时隙上承载的重复的RV不为0时，可以保证在不同的可能性中，在相同的有效时隙中传输PUSCH使用的RV是相同的，从而可以减小网络设备进行盲检的复杂度。
可选地，当所述第一参数为一个配置授权周期内的有效时隙数P，所述第二参数为所述每个重复中的有效时隙数N，且所述第一参数不为所述第二参数的整数倍，且参考有效时隙为所述一个配置授权周期内的有效时隙中的第一个时，最后P-floor(P/N)*N个有效时隙中不传输所述PUSCH；或者所述方法还包括：
根据第一RV和所述有效时隙数N进行编码，所述第一RV为最后P-floor(P/N)*N个有效时隙上承载的重复的RV；
将所述编码的结果从前往后在最后P-floor(P/N)*N个有效时隙中传输。
需要说明的是，这里的将所述编码的结果从前往后在最后P-floor(P/N)*N个有效时隙中传输，指的是，从最后P-floor(P/N)*N个有效时隙中第一个有效时隙开始传输。
示例性地，参见图14中的(a)，该第一参数可以为一个配置授权周期内的有效时隙数P(P＝16)，该第二参数可以为每个重复中的有效时隙数N(N＝4)，即第一参数不为第二参数的整数倍，参考有效时隙为配置授权周期内的第一个有效时隙。
则最后P-floor(P/N)*N＝16-floor(16/3)*3＝1个有效时隙不传输PUSCH；
或者，终端设备根据第一RV对所述有效时隙数N进行配置授权PUSCH的编码，该最后P-floor(P/N)*N＝16-floor(16/3)*3＝1个有效时隙上承载的重复的RV为3，即该第一RV为3，则对于最后1个有效时隙也进行配置授权PUSCH的编码，并将编码的结果在最后一个有效时隙中也传输，此时，传输的可能是部分内容，从而可以有效的利用资源，提升资源利用率。可选地，当所述第一参数为一个配置授权周期内的有效时隙数P，第二参数为一个配置授权周期内的重复的数量K，且所述第一参数不为所述第二参数的整数倍，且参考有效时隙为所述一个配置授权周期内的有效时隙中的第一个时，最后P-floor(P/K)*K个有效时隙中不传输所述PUSCH，或者所述方法还包括：
根据第一RV和有效时隙数N进行所述配置授权PUSCH的编码，所述第一RV为最后P-floor(P/K)*K个有效时隙上承载的重复的RV；
将所述编码的结果从前往后在最后P-floor(P/K)*K个有效时隙中传输。
该技术方案可以参见前文中的相关描述，为了简洁，不再赘述。
