一种可能的设计中，第一信令指示如下至少一项：第一起始符号、第一长度，第一起始符号以及第一长度用于指示第一符号。第一信令还指示如下至少一项：第二起始符号以及第二长度，第二起始符号以及第二长度用于指示第二符号。
一种可能的设计中，时域资源还包括第二时隙上的时域资源，第二时隙上的第一符号中不包括下行符号。通过上述设计，终端设备可以利用上行时隙和特殊时隙传输该上行传输块，从而可以提升传输效率。

具体实施方式
为便于理解本申请实施例，下面首先结合本申请中涉及的几个术语进行简单介绍。
1)时隙(slot)
一种slot的格式可以为包含若干个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。例如，一个slot的格式可以包括14个OFDM符号，或者，一种slot的格式可以为包含12个OFDM符号；或者，一种slot的格式为包含7个OFDM符号。一个slot中的OFDM符号可以全用于上行传输；可以全用于下行传输；也可以一部分用于下行传输，一部分用于上行传输，一部分灵活时域符号(可以灵活的配置为用于上行或者下行传输)。应理解，以上举例仅为示例性说明，不应对本申请构成任何限定。出于系统前向兼容性考虑，slot包含的OFDM符号的数目以及slot用于上行传输和/或下行传输不限于以上示例。本申请中，时域符号可以为OFDM符号，即时域符号可以替换为OFDM符号或者符号。
为了描述上的方便，本申请实施例中将用于上行传输的OFDM符号称为上行符号，将用于下行传输的OFDM符号称为下行符号，将可以灵活的配置为用于上行或者下行传输的符号称为灵活符号。并将所包括符号均为上行符号的时隙称为上行时隙，将所包括符号均为下行符号的时隙称为下行时隙。将包括上行符号和如下至少一项的时隙：下行符号或灵 活符号，或者，只包括灵活符号的时隙称为特殊时隙。
应理解，上述时隙和符号的命名仅是一种示例，并不限定于此。
2)物理时隙：可以理解为NR帧结构中定义的时隙，详见3GPP 38.211，这里不再展开叙述。
3)可用时隙：发送上行传输块实际使用的时隙。
4)传输时机(transmission occasions of TBoMS，TOT)
TOT为TBoMS的上行传输过程中涉及的一种时间单元，包括一个或多个用于上行传输的物理时隙。举例说明，TOT包括的时隙数可以为1,2,3,4,7,8,12,16等等。应理解，这里仅是一种举例说明，并不限定TOT的时隙数。
应理解，“TOT”仅是一种示例性命名，本申请实施例并不对这种时间单元的命名进行具体限定。
5)类型A(type A)的重复发送
type A的重复发送，指的是：N次重复需要调度连续的N个slot(如连续的N个物理时隙，又如连续的N个可用时隙)，配置一个slot中需要占用的时域符号的起始位置和总长度，N个slot中发送占用的时域符号的起始位置和总长度均满足配置的起始位置和总长度。其中，N为大于或等于1的整数。例如，假设配置了发送占据一个slot上的第2至第10个时域符号，那么每一个slot上的发送均需要在各个slot的第2至第10个时域符号上。

本申请实施例中，用于实现终端设备的功能的装置可以是终端设备，也可以是应用于终端设备中能够支持终端设备实现该功能的装置，例如具备通信功能的部件或组件，或者芯片系统，该装置可以被安装在终端设备中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端的功能的装置是终端设备为例，描述本申请实施例提供的技术方案。
7)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与终端设备通信的设备。网络设备可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(the 5th generation，5G)NR系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和/或分布式单元(distributed unit，DU)，本申请实施例并不限定。例如网络设备可以为Cloud RAN系统中的CU，或为DU，或为CU和DU的整体。

本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a和b,a和c,b和c,或a和b和c，其中a,b,c可以是单个，也可以是多个。
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大小、内容、顺序、时序、优先级或者重要程度等。例如，第一时间单元和第二时间单元，只是为了区分不同的时间单元，而并不是表示这两个时间单元的大小、优先级或者重要程度等的不同。
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。
为了增强NR的上行覆盖性能，提出TBoMS PUSCH技术。该技术将每个时隙上的小数据包聚合成一个大数据包，并在多个时隙上完成这个大数据包的传输。通过小包聚合能够降低包头开销，通过减少传输块(transport block，TB)的切分次数能够减少循环冗余码的开销，通过增加传输块大小(transport block size，TBS)能够提高编码增益，并通过降低物理资源块(physical resource block，PRB)数量能够提高功率谱密度，最终达成NR上行覆盖性能增强的目的。
目前，TBoMS传输的TDRA可以复用重复类型A的TDRA(repetition type A like TDRA)。即TBoMS在每个时隙上使用相同的符号分配。其中，每个时隙的起始符号和长度可以由TDRA表中起始和长度指示值(start and length indicator value，SLIV)(startSymbolAndLength字段)、和/或起始符号S(startSymbol字段)和长度L(length字段)指示。目前，当SLIV(或起始符号S、长度L)指示的符号中包括下行符号时，符号所在时隙不能用于PUSCH传输。而特殊时隙通常包括三部分，依次为下行符号，灵活符号和上行符号。因此，解决跨时隙传输的传输块只能利用上行时隙传输，上行覆盖性能较差。
基于此，本申请实施例提供一种通信方法及装置，用于解决跨时隙传输的传输块只能利用上行时隙传输，上行覆盖性能较差的问题。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例的技术方案可以应用于各种通信系统，例如：可以是物联网(internet of things，IoT)、窄带物联网(narrow band internet of things，NB-IoT)、LTE，也可以是第五代(5 th generation,5G)通信系统，还可以是LTE与5G混合架构，也可以是6G或者未来通信发展中出现的新的通信系统等。本申请所述的5G通信系统可以包括非独立组网(non-standalone，NSA)的5G通信系统、独立组网(standalone，SA)的5G通信系统中的至少一种。通信系统还可以是M2M网络、MTC或者其他网络。
为便于理解本申请实施例，首先结合图1说明适用于本申请实施例的通信系统。
图1是适用于本申请实施例的通信系统100的示意图。如图1所示，该通信系统100可以包括至少一个网络设备，例如图1所示的网络设备111，该通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备121。
本申请实施例也可用于其他通信系统，只要该通信系统中需要进行跨时隙的上行传输。另外申请实施例不仅适用于一个网络设备和一个UE通信的场景，而且适用于一个网络设备与多个UE通信，或者，多个网络设备协作同时与一个或多个UE进行通信的场景。图1仅是一种示意图，并不对通信系统的类型，以及通信系统内包括的设备的数量、类型等进行具体限定。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题同样适用。
本申请实施例中“在……情况下”、“若……”、“如果”、“当……时”等之间相互替换描述。例如，“在所述第一符号不包括用于下行传输的符号的情况下”，也可以描述为“若所述第一符号不包括用于下行传输的符号”，或者“如果所述第一符号不包括用于下行传输的符号”或者“当所述第一符号不包括用于下行传输的符号时”等等。
此外，下文实施例中，多次提到重复发送、重复传输或者重复发送上行传输块，对此本领域技术人员应理解其含义。重复发送、重复传输或者重复发送上行传输块，其均用于表示对于某一上行传输块，要发送一次或者多次。本申请实施例对每次发送的内容是否完全相同，不作限定。例如，在实际通信中，每次发送的RV可能是不同的。另，在本申请中，“上行传输块”均可以替换为“传输块”或者“数据”或“数据块”或者“上行数据”等等，或者在未来协议中，用于表示相同或相似含义的命名，都适用于本申请实施例。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
参见图2，为本申请提供的一种通信方法的流程示意图。该方法包括：
S201，网络设备向终端设备发送第一信令。相应的，终端设备接收来自网络设备的第一信令。
其中，第一信令用于指示上行传输块的TDRA，其中，该上行传输块可以在多个时隙发送，例如，该上行传输块为TBoMS。具体的，第一信令可以指示第一符号以及第二符号，第一符号包括至少一个符号，第二符号包括至少一个符号。
可选的，第一符号与第二符号有如下至少一项区别：起始符号不同、长度不同。
示例性的，第一信令可以指示第一起始符号和第一长度，其中，第一起始符号为分配给该上行传输块的第一时隙中的第一个符号，第一长度为分配给该上行传输块的第一时隙中的符号数。根据第一起始符号S1和第一长度L1可以确定以符号S1为起点，长度为L1的第一符号。举例说明，第一信令可以携带如下至少一个参数：第一SLIV、第一起始符号、或第一长度，其中，第一SLIV可以指示第一起始符号和第一长度。
可以理解的，上述第一符号的指示方式以第一起始符号和第一长度为例，在具体实施中，第一信令也可以通过第一结束符号与第一长度指示第一符号，或者，还可以通过第一起始符号和第一结束符号指示第一符号等等。
需要说明的是，上述第一起始符号、第一结束符号或第一长度也可以是默认的，例如，第一起始符号默认为时隙中的第一个符号，第一结束符号默认为时隙中的最后一个符号，第一长度默认为7个符号等等。
第二符号的指示方式与第一符号的指示方式类似，重复之处不再赘述。
此外，第一信令还可以指示起始时隙以及第一时隙数，第一时隙数指示分配给上行传输块的连续时隙的时隙数，也就是，第一时隙数指示分配给该上行传输块的物理时隙的数量。通过该方式，使得时域资源范围能够提前划分，实现更简单。
或者，第一信令还可以指示起始时隙以及第二时隙数，第二时隙数指示用于发送上行传输块的多个时隙的时隙数，也就是，第二时隙数指示该上行传输块的可用时隙的数量。通过该方式，可以使得发送的上行传输块携带信息完整，可靠性、覆盖性能更优。
一种示例性说明中，第一时隙数的候选值可以但不限于为：1，2，3，4，7，8，12，16，20，24，28，32，34，36，40，42等等。
第二时隙数的候选值可以但不限于为：1，2，3，4，7，8，12，16，20，24，28，32，34，36，40，42等等。
应理解，这里仅是对第一时隙数、第二时隙数进行举例说明，并不限定第一时隙数与第二时隙数的候选值相同，且在具体实施中，第一时隙数、第二时隙数的候选值也可以包括其他，或者包括上述举例中的部分，这里不做具体限定。
通过上述方式，终端设备可以确定发送上行传输块的时隙。
可选的，若该上行传输块采用重复传输(例如重复类型A)的方式进行发送，第一信令还可以指示重复间隔，重复间隔用于指示相邻两次重复之间的时间间隔。重复间隔的具体指示内容将在下文详细介绍。第一信令还可以指示上行传输块的重复次数。
示例一，重复间隔可以指示相邻两次重复传输的起始时隙之间的时间间隔。
示例二，重复间隔可以指示相邻两次重复传输中为前一次重复传输配置的多个时隙中的最后一个时隙与后一次重复传输的起始时隙之间的时间间隔。
示例三，重复间隔可以指示相邻两次重复传输中前一次重复传输中最后一个用于上行传输的时隙与后一次重复传输的起始时隙之间的时间间隔。
其中，时间间隔的单位可以为时隙、或第三时间单元、或迷你时隙、或子帧、或半帧、或帧、或上下行时隙配比周期、或毫秒，其中，第三时间单元可以参阅前文术语介绍中关于TOT的相关描述。为了便于描述，下面将第三时间单元称为TOT。
一种可能的实施方式中，第一信令指示第一时隙数时，重复间隔可以为示例一或示例二或示例三。第一信令指示第二时隙数时，重复间隔可以为示例一或示例三。
以上介绍了第一信令的指示内容，下面对第一信令的信令设计进行举例说明。应理解，下面的示例仅以第一信令包括前文涉及到的各个参数为例，并不限定第一信令包括以下示例中的所有参数。
该第一信令可以为无线资源控制(radio resource control，RRC)信令。第一信令可以通过RRC信令中TDRA表(PUSCH-TimeDomainResourceAllocationList)指示上行传输块的TDRA。下面介绍两种可能的TDRA表。
示例一，TDRA表中包括PUSCH分配表(puschAllocationList表)，该PUSCH分配表中包括以下字段中的至少一个字段：slotNum、startSymbolAndLength、startSymbol、Length、startSymbolAndLength2、startSymbol2、Length2、intervalOfRepetitions，其中，slotNum用于指示第一时隙数或第二时隙数，startSymbolAndLength用于指示第一SLIV，startSymbol用于指示第一起始符号，Length用于指示第一长度，startSymbolAndLength2用于指示第二SLIV，startSymbol2用于指示第二起始符号，Length2用于指示第二长度，intervalOfRepetitions用于指示重复间隔。该PUSCH分配表还可以包括其他字段，例如指示起始时隙的k2字段、指示第一类时隙中DMRS的映射方式的mappingType字段、用于指示重复次数的numberOfRepetitions字段等等，这里不再一一列举。
一种举例说明，TDRA表中包括k2以及PUSCH分配表，其中，PUSCH分配表包括mappingType、slotNum、startSymbolAndLength、startSymbol、Length、startSymbolAndLength2、startSymbol2、Length2、numberOfRepetitions、以及intervalOfRepetitions。
上述示例中，通过增加slotNum、startSymbolAndLength2、startSymbol2、Length2、intervalOfRepetitions等字段，使得第一信令可以指示第二符号、重复间隔、时隙数等信息。
示例二，TDRA表中包括PUSCH分配表(puschAllocationList表)，该PUSCH分配表中包括以下字段中的至少一个字段：startSymbolAndLength、startSymbol、Length、startSymbolAndLength2、startSymbol2、Length2、numberOfRepetitions，其中，numberOfRepetitions可以指示第一时隙数或第二时隙数，startSymbolAndLength用于指示第一SLIV，startSymbol用于指示第一起始符号，Length用于指示第一长度，startSymbolAndLength2用于指示第二SLIV，startSymbol2用于指示第二起始符号，Length2用于指示第二长度。该PUSCH分配表还可以包括其他字段，例如指示起始时隙的k2字段、 指示第一类时隙中DMRS的映射方式的mappingType字段等等，这里不再一一列举。
一种举例说明，TDRA表中包括k2以及PUSCH分配表，其中，PUSCH分配表包括mappingType、startSymbolAndLength、startSymbol、Length、startSymbolAndLength2、startSymbol2、Length2、以及numberOfRepetitions。
上述示例中，通过复用numberOfRepetitions字段来指示时隙数，从而可以降低信令开销。
需要说明的是，示例二可以应用于不支持重复传输的场景中。
此外，第一信令还可以指示第二类时隙中DMRS的映射方式。例如，第一信令的PUSCH分配表中可以包括mappingType2字段，该字段可以指示第二类时隙中DMRS的映射方式。
需要说明的是，在第一信令中指示第二类时隙中DMRS的映射方式仅是一种可能的实施方式。在具体实施中，第二类时隙中DMRS的映射方式也可以通过其他方式确定，例如，第二类时隙中DMRS的映射方式也可以是默认的，例如，第二类时隙中DMRS的映射方式可以默认为MappingTypeB。
S202，终端设备基于第一信令确定用于发送该上行传输块的时域资源。
在一些实施例中，终端设备基于第一信令确定用于发送该上行传输块的时域资源，可以包括：确定用于发送该上行传输块的时隙，以及每个时隙中用于发送该上行传输块的时域资源。
这里首先介绍每个时隙中用于发送该上行传输块的时域资源。
一种实现方式中，时隙的满足的条件不同，时隙上用于发送该上行传输块的时域资源不同。下面介绍不同条件下时隙中用于发送该上行传输块的时域资源的三个举例。
举例1，若时隙上的第一符号中不包括下行符号，则上行传输块的时域资源包括该时隙上的第一符号。或者，若时隙上的第一符号中包括下行符号，且该时隙上的第二符号中不包括下行符号，则上行传输块的时域资源包括该时隙上的第二符号，不包括第一时隙上的第一符号。
基于上述举例，终端设备可以根据第一信令确定用于发送该上行传输块的时域资源包括如下至少一项：第一时隙中的第二符号、或第二时隙中的第一符号。
其中，第一时隙中的第一符号包括下行符号，且第一时隙中的第二符号中不包括下行符号。第二时隙中的第一符号中不包括下行符号。
举例2，若时隙上的第一符号中不包括下行符号，且该时隙上的第二符号中不包括下行符号，则上行传输块的时域资源包括该时隙上的第一符号。或者，若时隙上的第一符号包括下行符号，且该时隙上的第二符号中不包括下行符号，则上行传输块的时域资源包括该时隙上的第二符号。
一种举例说明中，以时隙1～5为例，其中，时隙1～时隙2均包括14个下行符号，时隙3中符号0～7为下行符号，符号8～13为上行符号，时隙4～时隙5均包括14个上行符号。假设第一信令指示第一符号为0～11，第二符号为10～13。对于时隙1和时隙2，第一符号和第二符号均包括下行符号，则时隙1和时隙2上没有用于发送上行传输块的时域资源。对于时隙3，第一符号包括下行符号，第二符号均为上行符号，则时隙3中的符号10～13为用于发送上行传输块的时域资源。对于时隙4和时隙5，第一符号均为上行符号，则时隙4和时隙5中的符号0～11为用于发送上行传输块的时域资源。如图3所示。
基于上述举例，终端设备可以根据第一信令确定用于发送该上行传输块的时域资源包 括如下至少一项：第三时隙中的第二符号、或第四时隙中的第一符号。
其中，第三时隙中的第一符号包括下行符号，且第三时隙中的第二符号中不包括下行符号。第四时隙中的第一符号中不包括下行符号，且第四时隙中的第二符号中不包括下行符号。
举例3，若时隙上的第一符号不包括下行符号，且该时隙上的第二符号不包括下行符号，且该时隙上的第一符号的符号数量多于该时隙上的第二符号的符号数量，则上行传输块的时域资源包括该时隙上的第一符号。
或者，若该时隙上的第一符号不包括下行符号，且该时隙上的第二符号包括下行符号，则上行传输块的时域资源包括该时隙上的第一符号。
或者，若该时隙上的第一符号不包括下行符号，且该时隙上的第二符号不包括下行符号，且该时隙上的第一符号的符号数量不多于该时隙上的第二符号的符号数量，则上行传输块的时域资源包括该时隙上的第二符号。
或者，若该时隙上的第一符号包括下行符号，且该时隙上的第二符号不包括下行符号，则上行传输块的时域资源包括该时隙上的第二符号。
基于上述举例，终端设备可以根据第一信令确定用于发送该上行传输块的时域资源包括如下至少一项：第五时隙中的第一符号、或第六时隙中的第一符号、或第七时隙中的第二符号、或第八时隙中的第二符号。
其中，第五时隙上的第一符号不包括下行符号，且第五时隙上的第二符号不包括下行符号，且第五时隙上的第一符号的符号数量多于第五时隙上的第二符号的符号数量。
第六时隙上的第一符号不包括下行符号，且第六时隙上的第二符号包括下行符号。
第七时隙上的第一符号不包括下行符号，且第七时隙上的第二符号不包括下行符号，且第七时隙上的第一符号的符号数量不多于第七时隙上的第二符号的符号数量。
第八时隙上的第一符号包括下行符号，且第八时隙上的第二符号不包括下行符号。
可选的，基于上述举例3，第一信令可以指示第一类时隙中DMRS的映射方式以及第二类时隙中DMRS的映射方式。例如，第一信令可以包括mappingType字段以及mappingType2字段，其中，mappingType字段指示第一类时隙中DMRS的映射方式，mappingType2字段指示第二类时隙中DMRS的映射方式。
在上述三个举例中，根据第一符号和第二符号中是否包括下行符号来确定时隙中用于发送上行传输块的时域资源为第一符号还是第二符号。基于上述三个举例，这里还给出一种可选的方案，即在确定时隙中用于发送上行传输块的时域资源为第一符号时，除了满足上述三个举例中对应的条件以外，还要满足如下：如果该时隙有下行符号，且最后一个下行符号与第一符号的第一个上行符号之间的间隔不小于GP。在这个方案中，如果一个时隙满足了上述第二时隙、或第四时隙、或第五时隙、或第六时隙所满足的条件，且该时隙有下行符号，且最后一个下行符号与第一符号的第一个上行符号之间的间隔不小于GP，则可以确定该时隙中用于发送上行传输块的时域资源为第一符号。如果该时隙满足了上述第二时隙、或第四时隙、或第五时隙、或第六时隙所满足的条件，但是该时隙有下行符号，且最后一个下行符号与第一符号的第一个上行符号之间的间隔小于GP，则可以确定该时隙中用于发送上行传输块的时域资源为第二符号。
需要说明的是，上述三个举例仅以第一符号是否包括下行符号，和/或，第二符号是否包括下行符号为例，来确定时隙上用于发送该上行传输块的时域资源为第一符号还是第二 符号。在具体实施中，也可以根据第一符号是否包括如下至少一项：下行符号、灵活符号、保护间隔(guard period，GP)，和/或，第二符号中是否包括如下至少一项：下行符号、灵活符号、GP，来确定时隙上用于发送该上行传输块的时域资源为第一符号还是第二符号。
为了区分使用第一符号发送上行传输块的时隙和使用第二符号发送上行传输块的时隙，下面将使用第一符号发送上行传输块的时隙称为第一类时隙，将使用第二符号发送上行传输块的时隙称为第二类时隙。应理解，这里仅为了区分作用，并不限定时隙要根据满足的条件进行分类。
上文介绍了每个时隙中用于发送该上行传输块的时域资源，下面介绍确定用于发送该上行传输块的时隙的方法。
根据前文所述，第一信令可以指示起始时隙和第一时隙数，或者，指示起始时隙和第二时隙数。这里结合第一时隙数N和第二时隙数M对终端设备确定用于发送该上行传输块的时隙的方法进行说明。
在第一信令指示起始时隙和第一时隙数N的实施方式中，终端设备可以根据上述三个举例确定用于发送该上行传输块的时隙，其中，第一连续时隙以第一信令指示的起始时隙为起点，且长度为第一时隙数N。
应理解，用于发送该上行传输块的时隙以及每个时隙中用于发送该上行传输块的时域资源可以通过一个实现过程确定，以上述举例1为例，如图4所示，该实现过程可以如下：
S401，根据第一信令确定时隙n上的第一符号。执行S402。
其中，n的初始值为第一信令指示的起始时隙的索引。
S402，判断第一符号是否包括用于下行传输的符号。若是，执行S403，若否，执行S407。
S403，根据第一信令确定时隙n上的第二符号。执行S404。
S404，判断第二符号是否包括用于下行传输的符号。若是，执行S405，若否，执行S408。
S405，判断n的值是否小于(n+N-1)。若是，则执行S406。若否，则结束。
S406，将n的值加1。执行S401。
S407，确定用于发送该上行传输块的时域资源包括时隙n上的第一符号。执行S405。
S408，确定用于发送该上行传输块的时域资源包括时隙n上的第二符号。执行S405。
通过图4所示过程可以确定出用于发送该上行传输块的时隙以及每个时隙中用于发送该上行传输块的时域资源。
图4所述方法中将第一连续时隙中的第一类时隙和第二类时隙作为发送上行传输块的时隙，但是在具体实施中，第一传输时隙中可能存在一些第一类时隙/第二类时隙被其它高优先级信号或信道抢占，因此，终端设备在确定时域资源时可以将这些时隙排除掉。
举例说明，假设上下行时隙配比周期“DDDSUDDSUU”，起始时隙为第一个时隙，N＝10，即给上行传输块分配了10个时隙，除去下行时隙和被其它高优先级信号或信道抢占第二个上行时隙，该上行传输块实际使用了4个时隙，如图5所示。
在第一信令指示起始时隙和第二时隙数M的实施方式中，终端设备可以从第一信令指示的起始时隙开始，根据上述三个举例确定M个用于发送该上行传输块的时隙，并将计数器加1。否则，继续判断下一个时隙，直到计数器的值等于第二时隙数M。通过上述方式可以确定出M个用于发送上行传输块的时隙。
应理解，用于发送该上行传输块的时隙以及每个时隙中用于发送该上行传输块的时域资源可以通过一个实现过程确定，以上述举例1所示确定方法为例，如图6所示，该实现过程可以如下：
S601，根据第一信令确定时隙n上的第一符号。执行S602。
其中，n的初始值为第一信令指示的起始时隙的索引。
S602，判断第一符号是否包括用于下行传输的符号。若是，执行S603，若否，执行S607。
S603，根据第一信令确定时隙n上的第二符号。执行S604。
S604，判断第二符号是否包括用于下行传输的符号。若是，执行S605，若否，执行S608。
S605，判断计数器的值是否小于(M-1)。若是，则执行S606。若否，则结束。
其中，计数器的初始值为0。
S606，将n的值加1。执行S601。
S607，确定用于发送该上行传输块的时域资源包括时隙n上的第一符号，且计数器加1。执行S605。
S608，确定用于发送该上行传输块的时域资源包括时隙n上的第二符号，且计数器加1。执行S605。
通过图6所示过程可以确定出用于发送该上行传输块的时隙以及每个时隙中用于发送该上行传输块的时域资源。
图6所述方法中将确定的第一类时隙和第二类时隙作为发送上行传输块的时隙，但是在具体实施中，确定的第一类时隙/第二类时隙可能被其它高优先级信号或信道抢占，因此，终端设备在确定时域资源时可以将这些时隙排除掉。
举例说明，假设上下行时隙配比周期“DDDSUDDSUU”，起始时隙为第一个时隙，N＝5，即上行传输块实际使用5个时隙，除去下行时隙和被其它高优先级信号或信道抢占第二个上行时隙，为了保证上行传输块实际使用的时隙数为5，第二个上下行时隙配比周期中的第一个S时隙也会被用于上行传输块，如图7所示。
S203，网络设备基于第一信令确定用于发送该上行传输块的时域资源。
其中，网络设备确定时域资源的方式与终端设备相同，具体可以参阅S202，这里不再重复赘述。
需要说明的是，步骤S202和S203在执行上没有严格的时间顺序。
S204，终端设备在确定的时域资源上发送该上行传输块。相应的，网络设备在确定的时域资源上接收该上行传输块。
具体传输方式将在下文详细说明。
本申请实施例中通过第一信令使得终端设备可以有效的判别上行时隙和特殊时隙，并可以独立的指示上行时隙和特殊时隙中的时域资源，从而可以有效的利用特殊时隙发送上行传输块，并有利于提升资源利用率，提高传输效率。
下面对终端设备在确定的时域资源上发送该上行传输块的过程进行说明。
一种可能的实施方式中，终端设备在确定的时域资源上发送该上行传输块时，可以确定上行传输块对应的信息比特量，并根据信息比特量确定上行传输块对应的上行信号。终端设备在时域资源上发送该上行信号。
其中，该信息比特量可以根据用于缩放的参数K确定，K为上行传输块中第一时间单元对应的资源与第二时间单元对应的资源的比值。例如，信息比特量N info可以满足如下公式，或者，也可以理解为通过如下公式确定：
N info＝K·N RE·R·Q m·v；
其中，N RE为第二时间单元上的资源单元(resource element，RE)数，R表示码率，Q m表示调制阶次，v表示层数。
上述第一时间单元对应的资源指第一时间单元对应的资源中用于发送上行传输块的资源，第二时间单元对应的资源指第二时间单元对应的资源中用于发送上行传输块的资源。
上述资源可以指符号数(第一符号的符号数或第二符号的符号数)、或除DMRS的符号后的符号数、或一个PRB中的RE数N′ RE、或RE总数等等。
下面介绍第一时间单元、第二时间单元的几种可能的定义。
第一时间单元可以为如下至少一种：用于发送上行传输块的TOT中最长的TOT、或用于发送上行传输块的TOT中最短的TOT、或用于发送上行传输块的TOT中多个TOT、或用于发送上行传输块的所有时隙。
第二时间单元可以为如下至少一种：第一类时隙、或第二类时隙、或第一个用于发送上行传输块的TOT(即第一个可用的TOT)、或第一个用于发送上行传输块的时隙(即第一个可用的时隙)、或用于发送上行传输块的TOT中最长的TOT、或用于发送上行传输块的TOT中最短的TOT。
举例说明，假设上下行时隙配比为“DDDSUDDSUU”，上行传输块分配的时隙数为N＝15，起始时隙为第一个下行时隙，如图8所示。假设上行传输块包括三个TOT，其中第一个TOT为前两个“SU”时隙，第二个TOT为中间三个“SUU”时隙，第三个TOT为最后两个“SU”时隙。
若第一时间单元为用于发送上行传输块的TOT中最短的TOT，第一时间单元为图8的第一个TOT或第三个TOT，等等，这里不再一一展开说明。
若第二时间单元为第一个可用的时隙，第二时间单元为图8的第一个特殊时隙，等等，这里不再一一展开说明。
为了便于对方案的理解，下面集合第一时间单元、第二时间单元以及资源的各个示例解释K的定义。示例性的，如表1所示。
表1
Figure PCTCN2022110477-appb-000001
Figure PCTCN2022110477-appb-000002
Figure PCTCN2022110477-appb-000003
其中，其中L和L2分别表示第一符号长度和第二符号长度，L DMRS和L2 DMRS分别表示第一类时隙上的DMRS符号数和第二类时隙上的DMRS符号数，N′ RE和N′ RE2分别表示第一类时隙上的一个PRB中的RE数和第二类时隙上的一个PRB中的RE数，N RE和N RE2分别表示第一类时隙上的RE总数和第二类时隙上的RE总数。
需要说明的是，表1仅示出几种可能的K的定义，在具体实施中，K的定义也可以为其他，这里不再一一列举。
通过上述确定信息比特量的方式，可以在利用特殊时隙进行上行传输的前提下，使得信息比特量计算的更准确，提升信息传输的准确性。
以上介绍了上行传输块的一次传输的过程，在具体实施中，上行传输块也可以采用重复传输的方式进行发送。
其中，重复传输的次数可以是第一信令指示的，在这种方式中，若第一信令未指示重复传输的次数，可以认为该上行传输块不支持(或不进行)重复传输。
若该上行传输块进行重复传输，终端设备可以根据重复间隔确定下一次重复传输的时域资源。重复间隔的定义可以参阅上述步骤S201中介绍的重复间隔的三个示例。
其中，重复间隔可以为第一信令指示的，指示方式具体可以参阅前文中第一信令的相关描述。或者，重复间隔也可以是预配置的，例如，每次重复传输的起始时隙在上下行时隙配比周期的同一位置，等等。
下面结合重复间隔的不同示例对重复传输的起始位置进行说明。遍历该上行传输块的重复传输，记作重复#m，其中，m＝0,1,…,M-1；应理解，重复#0表示该上行传输块的第一次传输。
举例1，每次重复传输的起始时隙在上下行时隙配比周期的同一位置。示例性的，假设下行时隙配比周期为“DDDSUDDSUU”，重复#0的起始时隙为一个上下行时隙配比周期的第一个特殊时隙，则重复#m的起始时隙为另一个上下行时隙配比周期的第一个特殊时隙，如图9所示。
该方式中，通过预配置的重复间隔(或者默认的重复间隔)可以确定每次重复的起始位置。
举例2，结合重复间隔的示例一，重复#m的起始时隙与重复#m-1的起始时隙相差I。示例性的，假设上下行时隙配比周期为“DDDSUDDSUU”，且为上行传输块分配了10个时隙。为重复#m-1分配的时隙为一个上下行时隙配比周期的10个时隙，起始时隙为该上下行时隙配比周期的第一个下行时隙，假设重复间隔I＝10时隙，则重复#m的起始时隙为10个时隙后的时隙，即下一个上下行时隙配比周期的第一个下行时隙，如图10所示。
举例3，结合重复间隔的示例二，重复#m的起始时隙与分配给重复#m-1的最后一个时隙(即最后一个物理时隙)相差I。示例性的，假设上下行时隙配比周期为“DDDSUDDSUU”，且为上行传输块分配了7个时隙。为重复#m-1分配的时隙为一个上下行时隙配比周期的前7个时隙，重复#m-1分配的最后一个时隙为该上下行时隙配比周期的第五个下行时隙，假设重复间隔I＝6个时隙，则重复#m的起始时隙为下一个上下行时隙配比周期的第1个特殊时隙，如图11所示。
举例4，结合重复间隔的示例三，重复#m的起始时隙与重复#m-1实际使用的最后一个时隙(即最后一个可用时隙)相差I。示例性的，假设上下行时隙配比周期为“DDDSUDDSUU”，且为上行传输块分配了10个时隙。为重复#m-1分配的时隙为一个上下行时隙配比周期的10个时隙，重复#m-1实际使用的最后一个时隙为该上下行时隙配比周期的第二个上行时隙，假设重复间隔I＝4个时隙，则重复#m的起始时隙为下一个上下行时隙配比周期的第一个特殊时隙，如图12所示。
基于上述确定起始时隙，可以根据S202所述的方法确定每次重复传输中的时域资源。
通过上述确定重复传输的起始位置的方式，可以使得每一次重复传输的时域资源分配一致，从而可以复用现有技术重复类型A(repetition type A)。并且，通过上述方式，可以更为灵活的指示重复间隔，且可以指示更长的重复间隔，有助于获取时间分集增益，提升上行覆盖性能。
例如，以图4所述方法为例，假设上下行时隙配比周期“DDDSUDDSUU”，N＝10，则每一次重复传输分配的时隙数均为10，如图13所示，除去下行时隙和被其它高优先级信号或信道抢占第二个上行时隙，重复#0实际使用了4个时隙，重复#1实际使用了5个时隙。
又例如，以图6所述方法为例，假设上下行时隙配比周期“DDDSUDDSUU”，M＝4，则每一次重复传输实际使用时隙数都是4，如图14所示，除去下行时隙和被其它高优先级信号或信道抢占第二个上行时隙，重复#0实际使用了前两个特殊时隙和第一、三个上行时隙，重复#1实际使用了第三、第四个特殊时隙和第四、五个上行时隙。
需要说明的是，本申请实施例中提供的重复间隔的定义以及确定重复间隔的起始时隙的方法可以不依赖于图2所述的方法单独实施。此外，本申请实施例提供的确定根据用于缩放的参数K确定所述上行传输块对应的信息比特量的方法也可以不依赖于图2所述的方法单独实施。
本申请实施例中通过第一信令使得终端设备可以有效的判别上行时隙和特殊时隙，并可以独立的指示上行时隙和特殊时隙中的时域资源，从而可以有效的利用特殊时隙发送上行传输块，并有利于提升资源利用率，提高传输效率。
并且，通过上述确定信息比特量的方式，可以在利用特殊时隙进行上行传输的前提下，使得信息比特量计算的更准确，提升信息传输的准确性。
此外，通过上述确定重复传输的起始位置的方式，可以使得每一次重复传输的时域资源分配一致，从而可以复用现有技术重复类型A(repetition type A)。并且，通过上述方式，可以更为灵活的指示重复间隔，且可以指示更长的重复间隔，有助于获取时间分集增益，提升上行覆盖性能。
