At this time, if the number of symbols of the resource used for sending the PUSCH is small, the resource after frequency hopping needs to carry the DMRS alone, which will result in fewer resources for sending the PUSCH data, and reduce the resource utilization rate. For example, referring to FIG. 6 , on time slot n, the resources used for sending PUSCH are from symbol 8 to symbol 13. At this time, if PUSCH is not sent with frequency hopping, only one symbol is required to carry DMRS among the six symbols. If If the PUSCH is transmitted by frequency hopping, 2 symbols out of 6 symbols are required to carry the DMRS, which reduces the resources for transmitting the PUSCH data and reduces the resource utilization rate.

具体实施方式
在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种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这三种情况。在本申请的描述中，除非另有说明，“至少一个”是指一个或多个，“多个”是指两个或多于两个。
另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了便于理解本申请，首先对本申请实施例涉及到的部分概念和内容作简单介绍。
1、时隙(slot)
在新无线(new radio，NR)中，对于常规(normal)循环前缀(cyclic prefix，CP)，1个时隙包含14个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号(下文中简称为符号)。对于扩展(extended)CP，1个时隙包含12个符号。为了方便描述，本申请中以一个时隙包含14个符号为例进行描述，但是不限制一个时隙只能包含14个符号。
在时隙中，14个符号按照从小到大的顺序依次编号，最小的编号为0，最大的编号为13。本申请实施例中将索引(即编号)为i的符号记为符号i，则一个时隙包含符 号0至符号13。另外，本申请下文中将索引(即编号)为f的时隙记为时隙f。f为大于或等于0的整数，i为大于或等于0小于或等于13的整数。本申请中以时隙和符号均从0开始编号为例进行描述，在实际实现时，时隙和/或符号的编号还可以从1或其他数字开始，本申请不作限制。
一个时隙可以由一种或多种类型的符号构成。符号的类型包括：用作下行发送的符号(记为下行符号)、用作灵活传输的符号(记为灵活符号)、用作上行发送的符号(记为上行符号)、保护间隔符号等。时隙的构成可以称为时隙格式(slot format，SF)。
时隙可以分为上行时隙、下行时隙和特殊时隙。上行时隙是指仅包括上行符号的时隙，下行时隙是指仅包括下行符号的时隙，特殊时隙是指包括下行符号、上行符号和灵活符号中的至少两种的时隙。
2、资源元素(resource element，RE)
RE是物理资源中最小的资源单位。在时域上占用1个符号，频域上占用1个子载波。
3、解调参考信号(de-modulation reference signal，DMRS)
DMRS用于实现PUSCH的解调。DMRS承载于PUSCH中的部分符号上。PUSCH包括DMRS和数据。
4、PUSCH的映射类型(mapping type)
PUSCH包括两种mapping type，分别为：Type A和Type B。mapping type可以理解为资源分配类型。在NR的通信标准中，Type A和Type B都指示了起始符号(标识为S)，符号长度(标识为L)，以及S+L的可能值范围，示例性的，第三代合作伙伴计划(3rd generation partnership project，3GPP)技术规范(Tchnology Standard，TS)38.214中6.1.2.1章节中的表6.1.2.1-1(本申请中记为表1)示出了Type A和Type B下，有效的S和L的组合(Valid S and L conbinations)。
表1：有效的S和L的组合
Figure PCTCN2021134624-appb-000001
其中，Type A一行的参数仅适用于Type A的重复发送(repetition Type A only)。Type B一行的S+L一列中的“{1,…,14}”和“{1,…,12}”适用于Type A的重复发送(for repetition Type A)，Type B一行的S+L一列中的“{1,…,27}”和“{1,…,23}”适用于Type B的重复发送(for repetition TypeB)。
表1可以称为时域资源分配(time domain resource assignment，TDRA)表。
5、PUSCH的时域资源分配
目前，网络设备可以通过高层信令(例如，无线资源控制(radio resource cntrol，RRC)信令)为终端配置PUSCH的默认的时域资源分配表(TimeDomainAllocation List)， 该时域资源分配表中包括多行，一行为一个时域资源分配参数的组合，每行对应一个行索引。每行包括如下参数配置：PUSCH mapping type、K 2、起始和长度指示值(start and length indicator value，SLIV)。
其中，PUSCH mapping type为Type A或者Type B。K 2用于配置PUSCH所在的时隙相比调度该PUSCH的下行控制信息(downlink control information，DCI)所在时隙的偏置，例如，调度PUSCH的DCI所在的时隙为时隙n-K 2，则PUSCH发送的时隙为时隙n。SLIV用于配置PUSCH的起始符号S和符号长度L，S和L满足上述表1的限定。
具体的，PUSCH需要通过物理下行控制信道(physical downlink control channel，PDCCH)进行调度。DCI格式(DCI Format)0-0和DCI Format 0-1用于调度PUSCH。DCI中的时域资源指示域(Time domain resource assignment)字段对应时域资源分配表中的行。PUSCH的时域资源通过两个参数来确定，通过K 2确定PUSCH的发送时隙，通过S和L确定在该时隙内PUSCH占据的符号位置。
示例性的，默认的时域资源分配表可以为表2。其中，j通过μ PUSCH确定，μ PUSCH的取值可参见表3，μ PUSCH与子载波间隔有关，子载波间隔为15*2 μKHz(千赫兹)。j和μ PUSCH的对应关系可参见表3。

若S＝10，L＝14，则参见图1，PUSCH的发送位置为从第一个承载PUSCH的时隙(假设为时隙n)中第11个符号(即起始符号10)开始，持续14个符号。由于一个时隙的符号个数为14，因此持续的14个符号包括时隙n中的后4个符号和时隙n+1中的前10个符号。在这种跨2个时隙的情况下，从时隙n中的第11个符号到下一个时隙中的第10个符号记为一次名义重复(nominal repetition)，从时隙n中的第11个符号到时隙n中的第14个符号记为一个实际重复(actual repetition)(即实际重复0)，从时隙n+1中的第1个符号到时隙n+1中的第10个符号记为另一个实际重复(即实际重复1)。
6、PUSCH的频域资源分配
PUSCH频域资源通过PDCCH的频域资源指示域进行指示。频域资源有两种指示方法。
第一种指示方式是类型0(type0)。该指示方法的频域粒度为资源块组(resource block groups，RBG)。以带宽为10个资源块(resource block，RB)，RBG的大小(即RBG中包含的RB的个数)为2为例，如图2所示，可以将10个RB分为5组，得到5个RBG。通过位图(bitmap)的形式指示PUSCH占用的频域资源。以PDCCH中指示信息为10001为例，则PUSCH占用RBG0和RBG4。
第二种指示方式是类型1(type1)，该指示方式中PDCCH中指示频域的RB的起始位置(记为RB start)和L＇，L＇表示占用RB的长度。以带宽为10个RB为例，参见图3，若RB start＝2，L＇＝3。则PUSCH占用的频域资源为RB2，RB3和RB4。
7、冗余版本(redundancy version，RV)
传输块(transport block，TB)经过信道编码(turbocoder)后的数据包括三段，第一段可以认为是系统比特(即信息比特)，其余两段是冗余数据，这三段数据依次放在一个环形缓冲区内。RV其实就是指示从这个环形缓冲区的哪个位置开始取数据。目前，RV包括索引为0，2，3和1的RV，可以分别记为RV0、RV2、RV3和RV1。RV0、RV2、RV3和RV1各自对应一个在环形缓冲区内取数据的开始位置。其中，RV0中包含的系统比特最多，RV1和RV3次之，RV2最少。
其中，TB的大小(TB size，TBS)，也就是TB包含的比特(bit)数，可以根据用于发送PUSCH的RE的个数确定，用于发送PUSCH的RE的个数可以根据名义重复包含的符号个数、网络设备配置的用于发送PUSCH的RB个数以及DMRS的资源个数等信息确定。例如，若用于发送PUSCH的RE的个数为396，TBS为120比特，若对TB进行信道编码后的数据包含360比特，则396个RE用来发送这360个比特。若用于发送PUSCH的RE的个数大于编码出的数据中的比特数，剩余的资源上可以不承载任何比特。
本申请实施例中所描述的发送PUSCH可以理解为发送PUSCH上承载的数据，PUSCH上承载的数据是指对TB经过信道编码后得到的数据。
由于信道编码的过程描述起来比较繁琐，因此，本申请中描述到信道编码时采用了简化描述。具体的，本申请下文中的描述中，若描述到基于某些可用符号对TB进行信道编码，其含义为基于这些可用符号的个数、网络设备配置的用于发送PUSCH的RB个数以及DMRS的资源个数等信息确定TBS，并对TB进行信道编码；若描述 到基于某些资源进行信道编码，则其含义为基于这些资源中的可用符号的个数、网络设备配置的用于发送PUSCH的RB个数以及DMRS的资源个数等信息确定TBS，并对TB进行信道编码。
8、PUSCH的重复发送
PUSCH的重复发送是指发送多个PUSCH，多个PUSCH为多份相同的上行数据。一个PUSCH(即一份上行数据)的发送可以称为PUSCH的一次重复发送。多份相同的上行数据是指同一份系统比特经过信道编码之后所得到的多份相同或不同的RV。重复发送时，是基于L个可用符号对TB进行信道编码的。
针对Type B，通信标准引入参数“重复次数(numberOfRepetitions-r16)”配置重复次数，numberOfRepetitions-r16共有8个可配置值，由3bit指示，这3bit的各种值依次对应{n1,n2,n3,n4,n7,n8,n12,n16}，n之后的数值表示重复次数，例如，n1表明发送1次，n16表明发送16次。网络设备可以通过高层信令，例如，RRC信令为终端配置上述8个可配置值中的一个值，从而为终端指示重复次数。针对Type B，从重复发送PUSCH的起始时隙中的起始符号S开始，L*numberOfRepetitions-r16个可用符号，均用于PUSCH的重复发送。本申请中的“*”是指“乘以”。例如，参见图4，若S＝8，L＝14，重复次数＝4，从时隙n中的起始符号8开始，L*4个可用符号，均用于重复发送PUSCH。其中，从时隙n中的起始符号8开始每L个可用符号记为一个名义重复，一个名义重复中的位于同一个时隙中的符号记为一个实际重复。每个实际重复上发送PUSCH的一个RV，每个实际重复上发送的RV的一种可能的情况可参见图4。该方法可以尽可能的利用所有的可用符号重复发送PUSCH。
针对Type A，S+L是小于或等于14的。当终端被配置了重复次数(假设为R1)时，终端会在R1个时隙(从起始时隙开始的连续R1个时隙)中的每个时隙进行检测，当某个时隙内从起始符号S开始的L个符号均为可用符号，则在该时隙上发送PUSCH，否则放弃在该时隙上发送PUSCH，继续看其他时隙是否满足条件。
本申请中的可用符号不为下行符号、下行转上行的灵活符号以及被其他传输占用的符号。
9、重复发送的PUSCH的RV
为使接收端能够借助增量冗余(incremental redundancy，IR)的合并接收方法来提升译码能力，网络设备会通过配置使得PUSCH多次重复发送时采用不同的RV。每次PUSCH发送所采用的RV通过本次发送对应的实际重复的索引p以及用于调度PUSCH的DCI中的RV指示域所指示的rv id共同确定，rv id是指RV的索引。例如，3GPP TS 38.214中规定，用于发送PUSCH的索引为p的实际重复对应的RV由表4确定。表4中的“mod”是指“取余”。
表4

Figure PCTCN2021134624-appb-000003
10、跳频
跳频是指频域资源发生变更。跳频发送PUSCH是指在两个连续的时域资源上采用不同的频域资源发送PUSCH。本申请的描述中，跳频发送PUSCH是指在时隙内采用跳频方式发送PUSCH，非跳频发送PUSCH是指在时隙内不采用跳频方式发送PUSCH。
以上是对本申请实施例涉及到的部分概念和内容所作的简单介绍。
本申请实施例的技术方案可以应用于第四代(4th Generation，4G)系统、基于4G系统演进的各种系统、第五代(5th-generation，5G)系统、基于5G系统演进的各种系统中、或者应用于未来演进系统或者多种通信融合系统。其中，4G系统也可以称为演进分组系统(evolved packet system，EPS)。4G系统的核心网(core network，CN)可以称为演进分组核心网(evolved packet core，EPC)，接入网可以称为长期演进(long term evolution，LTE)。5G系统的核心网可以称为5GC(5G core)，接入网可以称为NR。其中，5G系统可以为非独立组网(non-standalone，NSA)的5G系统或独立组网(standalone，SA)的5G系统。
本申请涉及到的网元包括通信系统中的网络设备和终端。参见图5，本申请实施例提供的方法主要涉及网络设备和终端之间的通信。网络设备和终端可以通过空口(Uu口，即UTRAN-to-UE接口)通信。
本申请实施例中的网络设备为网络侧的一种用于发送信号，或者，接收信号，或者，发送信号和接收信号的实体。网络设备可以为部署在无线接入网(radio access network，RAN)中为终端提供无线通信功能的装置，例如可以为传输接收点(transmission reception point，TRP)、基站、各种形式的控制节点(例如，网络控制器、无线控制器(例如，云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器))等。具体的，网络设备可以为各种形式的宏基站，微基站(也称为小站)，中继站，接入点(access point，AP)等，也可以为基站的天线面板。所述控制节点可以连接多个基站，并为所述多个基站覆盖下的多个终端配置资源。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。例如，通用移动通信系统(universal mobile telecommunications system，UMTS)或LTE系统中可以为宏基站演进型基站(evolved NodeB，eNB或eNodeB)，在异构网络(heterogeneous network，HetNet)场景下可以为微基站eNB，在分布式基站场景可以是基带单元(base band unit，BBU)和射频拉远单元(remote radio unit，RRU)，在CRAN场景下可以是基带池(BBU pool)和RRU，5G系统或NR系统中可以为下一代基站节点(next generation node base station，gNB)，本申请对基站的具体名称不作限定。网络设备还可以是未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
本申请实施例中的终端是用户侧的一种用于接收信号，或者，发送信号，或者，接收信号和发送信号的实体。终端用于向用户提供语音服务和数据连通性服务中的一种或多种。终端还可以称为用户设备(user equipment，UE)、终端设备、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信设 备、用户代理或用户装置。终端可以是移动站(mobile station，MS)、用户单元(subscriber unit)、无人机、物联网(internet of things，IoT)设备、无线局域网(wireless local area networks，WLAN)中的站点(station，ST)、蜂窝电话(cellular phone)、用户手持通信设备(例如，智能电话(smart phone)、手机、平板电脑)、无绳电话、无线数据卡、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备(例如，车载通信模块或其它嵌入式通信模块)、可穿戴设备(也可以称为穿戴式智能设备)。终端还可以为未来演进的PLMN中的终端等。
网络设备和终端之间的PUSCH发送会存在以下2个问题。
问题1
终端在发送PUSCH时，会根据网络设备的配置确定是否跳频发送PUSCH，在网络设备配置跳频发送PUSCH的情况下，终端跳频发送PUSCH。此时，若用于发送PUSCH的资源的符号个数较少，跳频后的资源需要单独承载DMRS，会导致发送PUSCH的数据的资源变少，降低了资源利用率。例如，参见图6，在时隙n上，用于发送PUSCH的资源为符号8至符号13，此时，若非跳频发送PUSCH，则6个符号中只需要一个符号来承载DMRS即可，若跳频发送PUSCH，则6个符号中需要2个符号来承载DMRS，会导致发送PUSCH的数据的资源变少，降低了资源利用率。
问题2
在上述图5所示的架构中，存在网络设备到终端的下行发送和终端到网络设备的上行发送。由于网络设备成本相对较高，下行发送的覆盖范围一般会高于上行发送的覆盖范围。由于终端侧成本限制因素，只能使用较廉价的功率放大器，其功率上限也相对网络设备侧要低，因此覆盖增强的研究主要集中于如何提高上行发送的覆盖范围。上行发送一般包含物理上行控制信道(physical uplink control channel，PUCCH)和PUSCH。其中，PUCCH属于控制信道，发送信息量小，不需要太高的信噪比(signal noise ratio，SNR)，即使终端距离网络设备较远，也可以满足SNR的需求，因此，覆盖范围相对较广。PUSCH属于数据信道，发送信息量大，需要更高的SNR，终端距离网络设备较近时，才可以满足SNR需求，因此，覆盖范围相对较小。因此，如何提高PUSCH的覆盖范围是更加紧迫的问题。
目前讨论到的一种提高PUSCH的覆盖范围的方法是跨多个时隙承载1个TB(1 TB over multiple slots)，通过整合多个时隙(例如，图7中的时隙n至时隙n+2)上的资源，在发送PUSCH上承载的数据时可以采用更低的码率，从而不需要太高的SNR，进而提升PUSCH的覆盖。该方案目前仅仅在讨论阶段，具体如何实现跨多个时隙承载1个TB，目前并没有解决方案。
问题3
为了提高PUSCH的覆盖范围，除了跨多个时隙承载1个TB，还可以在多个时隙内重复发送PUSCH，重复次数越多，PUSCH可以纳入更多的符号，此时，可以适当的降低SNR，提高PUSCH的覆盖范围。目前，如何确定发送PUSCH或重复发送PUSCH 的多个时隙也是一个需要解决的问题。
为了解决上述问题，本申请提供了一种数据传输方法，该数据传输方法可以通过以下实施例一或实施例二实现。实施例一中，终端可以根据可用符号的个数确定是否跳频发送PUSCH，可以在符号个数较多的情况下跳频发送PUSCH，在符号个数较少的情况下非跳频发送PUSCH，从而提高资源利用率，解决上述问题1。实施例二提供了如何实现跨多个时隙承载1个TB的方案，解决上述问题2。实施例三提供了确定发送PUSCH或重复发送PUSCH的多个时隙的方法，解决上述问题3。以下对实施例一、实施例二和实施例三提供的方法分别进行描述。
实施例一
参见图8，实施例一提供的方法包括：
801、网络设备向终端发送时隙格式和PUSCH参数。相应的，终端接收来自于网络设备的时隙格式和PUSCH参数。
本申请各个实施例中，网络设备执行的动作也可以由位于网络设备外部或内部的芯片执行，终端执行的动作也可以由位于终端外部或内部的芯片执行。为了方便描述，本申请以网络设备和终端为例对本申请提供的方法做示例性说明。
其中，时隙格式用于指示时隙中各个符号的类型。网络设备可以半静态或动态的为终端配置时隙格式，具体配置过程为本领域技术人员所公知的，不再赘述。PUSCH参数用于确定PUSCH资源。PUSCH资源包括PUSCH时域资源和PUSCH频域资源。PUSCH参数包括时域参数和频域参数。时域参数用于确定PUSCH时域资源，频域参数用于确定PUSCH频域资源。时域参数可以包括以下信息中的一个或多个：用于指示时隙个数的信息(具体内容可参见实施例二)，重复次数，对应起始符号S、符号个数L和K 2的一个索引(例如，表2中的一个行索引)。其中，时隙个数是指承载一个TB的时隙的个数，多个时隙承载一个TB时，基于多个时隙中的部分或全部可用符号对TB进行信道编码，并在多个时隙上发送PUSCH(即信道编码后的数据)。频域参数包括用于指示PUSCH频域资源的参数(例如，位图、RB start和L＇)，具体可参见上文中关于PUSCH的频域资源分配的内容。PUSCH参数也可以称为PUSCH调度参数。
其中，PUSCH参数可以携带在RRC信令和/或DCI中。
802、终端根据时隙格式和PUSCH参数确定第一时隙中的第一资源，第一资源由可用符号组成。
其中，第一时隙可以为上行时隙，也可以为特殊时隙(例如，下行转上行的时隙)，本申请不作限制。第一资源包括上行符号和部分灵活符号，不包括下行符号和下行到上行转换的灵活符号。第一资源中的可用符号在时域上是连续的。本申请中的第一资源是指时域资源，终端可以根据频域参数确定第一资源对应的频域资源，具体过程可参见上文中关于PUSCH的频域资源分配的内容，不再赘述。
第一时隙具体可以通过以下情况1或情况2确定，以下对情况1和情况2以及这两种情况下第一时隙中的第一资源的确定进行阐述：
情况1、当仅在一个时隙上发送PUSCH时，该时隙即第一时隙。
在情况1下，终端可以根据时域参数指示的K 2和调度PUSCH的DCI所在的时隙 (假设为时隙n-K 2)确定发送PUSCH的时隙为时隙n。一种情况下，第一资源为时隙n内的可用符号组成的资源。另一种情况下，终端还可以根据时隙格式、以及时域参数指示的起始符号S和符号个数L(S+L小于或等于14)确定第一资源，若时隙n中的从起始符号S开始的L个符号均为可用符号，则第一资源为时隙n中的从起始符号S开始的L个符号。例如，参见图9，若S＝2，L＝10，若从起始符号S开始的10个符号(即符号2至符号11)均为可用符号，则确定时隙n中的符号2至符号11为第一资源。
情况2、第一时隙为N个时隙中的一个时隙，N为大于1的整数。
其中，N个时隙可以有以下几种情况：
(1)N个时隙为从起始时隙开始连续的N个时隙。
(2)N个时隙为从起始时隙开始的不包括下行时隙的N个时隙。
(3)N个时隙为从起始时隙开始的不包括下行时隙和特殊时隙的N个时隙。
(4)N个时隙为从起始时隙开始的N个上行时隙。
(5)N个时隙为从起始时隙开始的满足每个时隙中的从起始符号S开始的符号均为可用符号的N个时隙。也就是说，这N个时隙中每个时隙中的从起始符号S开始的符号均为可用符号。
(6)N个时隙为从起始时隙开始的满足每个时隙中的从起始符号S开始的L个符号均为可用符号的N个时隙。也就是说，这N个时隙中每个时隙中的从起始符号S开始的L个符号均为可用符号。
(7)N个时隙为从起始时隙中的起始符号S开始L*X个可用符号对应的时隙。其中，X为时隙个数或重复次数。例如，基于图10所示的时隙格式，若起始时隙为时隙n，S＝8，L＝14，重复次数或时隙个数为4，则N个时隙为时隙n至时隙n+5。
(8)N个时隙为满足起始时隙中的从起始符号S开始的L个符号均为可用符号、且N个时隙中的其他时隙的符号均为可用符号的N个时隙。也就是说，这N个时隙中的起始时隙中的从起始符号S开始的L个符号均为可用符号，这N个时隙中的第2个时隙至第N个时隙中的符号均为可用符号。
(9)N个时隙为满足起始时隙中的从起始符号S开始的符号均为可用符号、且N个时隙中的其他时隙的符号均为可用符号的N个时隙。也就是说，这N个时隙中的起始时隙中的从起始符号S开始的符号均为可用符号，这N个时隙中的第2个时隙至第N个时隙中的符号均为可用符号。
(10)N个时隙为从起始时隙开始的存在可用符号的N个时隙。也就是说，N个时隙中的每个时隙都存在可用符号。
(11)N个时隙为从起始时隙开始的满足可用符号个数大于或等于第五阈值的N个时隙。也就是说，N个时隙中的每个时隙中的可用符号个数都大于或等于第五阈值。此处的大于或等于也可以替换为大于。第五阈值可以为预设的，或，协议规定的，或网络设备和终端协商确定的，本申请不作限制。
需要说明的是，N的取值可以是PUSCH参数直接或间接配置的。N个取值也可以是终端自己确定的，例如，PUSCH参数配置一个N＇，此时，终端可以根据时隙格式确定N个时隙。例如，终端确定从起始时隙开始的N＇个时隙内的满足上述某个情况 所述的特征的所有时隙为该情况中的N个时隙。例如，对于情况(1)，从起始时隙开始的N＇个时隙内的连续的时隙为N个时隙，此时N个时隙即该N＇个时隙。对于情况(2)，从起始时隙开始的N＇个时隙内的不为下行时隙的全部时隙为N个时隙。对于情况(3)，从起始时隙开始的N＇个时隙内的不为下行时隙和特殊时隙的全部时隙为N个时隙。对于情况(4)，从起始时隙开始的N＇个时隙内的全部的上行时隙为N个时隙。对于情况(5)，从起始时隙开始的N＇个时隙内的满足从起始符号S开始的符号均为可用符号的全部时隙为N个时隙。其他情况可类似推导，不再赘述。
上述情况(5)至情况(9)中，S和L可以为PUSCH参数配置的。
情况(1)确定的N个时隙中可能有无法使用的时隙，例如，若N个时隙中存在下行时隙，则该时隙无法用于发送PUSCH，而情况(2)至情况(11)相比情况(1)而言，确定的N个时隙都可以用于发送PUSCH。若N个时隙为情况(1)所描述的N个时隙，则N个时隙中的满足一定条件的时隙用于发送PUSCH。该条件为时隙中的从起始符号S开始的L个符号为可用符号(也就是说，对于N个时隙中的每个时隙，只有该时隙中的从起始符号S开始的L个符号为可用符号，该时隙才可以用于发送PUSCH)，或者，该条件为时隙存在可用符号(也就是说，对于N个时隙中的每个时隙，只有该时隙中存在可用符号，该时隙才可以用于发送PUSCH)，或者，该条件为时隙中的从起始符号S开始的符号均为可用符号(也就是说，对于N个时隙中的每个时隙，只有该时隙中的从起始符号S开始的符号均为可用符号，该时隙才可以用于发送PUSCH)。
终端可以根据时域参数指示的K 2和调度PUSCH的DCI所在的时隙(假设为时隙n-K 2)确定发送PUSCH的起始时隙为时隙n。
在第一种场景下，N个时隙用于发送PUSCH。“N个时隙用于发送PUSCH”是指在N个时隙上发送对TB进行信道编码后的数据，该TB基于N个时隙中的部分或全部可用符号进行信道编码。其中，该TB可以基于N个时隙中的全部可用符号进行信道编码，也可以基于N个时隙中的用于发送PUSCH的可用符号进行信道编码，也可以基于N个时隙中的部分时隙(例如，连续的上行时隙)中的全部可用符号进行信道编码，还可以基于N个时隙中的部分时隙(例如，连续的上行时隙)中的用于发送PUSCH的可用符号进行信道编码。例如，假设该TB基于N个时隙中的全部可用符号进行信道编码，若N个时隙为图11中所示的6个时隙，N个时隙上发送的数据可以是基于图11中的资源0至资源5中的可用符号对TB进行信道编码后的数据。再例如，假设该TB基于N个时隙中的用于发送PUSCH的可用符号进行信道编码，若N个时隙为图12中所示的6个时隙，假设N个时隙中的用于发送PUSCH的可用符号为N1个时隙中的每个时隙中的从起始符号S开始的L个符号，N1个时隙为N个时隙中的满足从起始符号S开始的L个符号均为可用符号的时隙，则若S＝2，L＝10，那么N个时隙中的用于发送PUSCH的可用符号为图12中的资源0至资源3，N个时隙上发送的数据可以是基于资源0至资源3对TB进行信道编码后的数据。再例如，假设该TB基于N个时隙中的连续的上行时隙中的全部可用符号进行信道编码，若N个时隙为图12中所示的6个时隙，N个时隙上发送的数据可以是基于时隙n+1和时隙n+2中的可用符号对TB进行信道编码后的数据。
在第一种场景下，终端可以根据PUSCH参数中的用于指示时隙个数的信息，或者，PUSCH参数中的用于指示时隙个数的信息和时隙格式确定N个时隙(具体根据用于指示时隙个数的信息确定N的取值，根据时隙格式确定N个时隙为哪些时隙，或者，根据S和L确定从起始时隙中的起始符号S开始L*X个可用符号，再根据这些可用符号确定N个时隙，X为时隙个数)。
在第二种场景下，N个时隙用于重复发送PUSCH。“N个时隙用于重复发送PUSCH”是指，在N个时隙上发送基于N个时隙中的某个时隙(例如，第一个时隙，或，可用符号个数最多的时隙)中的可用符号对TB进行信道编码后的数据，或者，“N个时隙用于重复发送PUSCH”是指在N个时隙上发送基于L个可用符号对TB进行信道编码后的数据。此时，终端可以根据PUSCH参数中的重复次数，或者，PUSCH参数中的重复次数和时隙格式确定N个时隙(具体根据重复次数确定N的取值，根据时隙格式确定N个时隙为哪些时隙，或者，根据S和L确定从起始时隙中的起始符号S开始L*X个可用符号，再根据这些可用符号确定N个时隙，X为重复次数)。
第一时隙可以为N个时隙中的上行时隙或特殊时隙。
第一资源可以为第一时隙中的可用符号组成的资源。例如，N个时隙为图11中所示的6个时隙，若第一时隙为时隙n，则第一资源可以为资源0，若第一时隙为时隙n+1，则第一资源可以为资源1。
第一资源也可以为第一时隙中的从起始符号S开始的L个可用符号组成的资源，此时，第一时隙为从起始符号S开始的L个符号均为可用符号的时隙。例如，N个时隙为图12中所示的6个时隙，若第一时隙为时隙n+1，则第一资源为资源0，若第一时隙为时隙n+2，则第一资源为资源1。
第一资源还可以为第一时隙中的用于发送同一个RV的资源，此时，第一资源也就是一个实际重复对应的资源。例如，N个时隙为图10中所示的6个时隙，若第一时隙为时隙n，则第一资源可以为资源0，若第一时隙为时隙n+1，则第一资源可以为资源1，也可以为资源2。
803、网络设备根据时隙格式和PUSCH参数确定第一时隙中的第一资源。
步骤803的具体实现过程与步骤802类似，区别仅在于此处为网络设备，可参考进行理解，不再赘述。
步骤803可以执行在步骤802之后，也可以执行在步骤802之前，本申请不作限制。
804、终端根据第一资源中的可用符号个数确定是否在第一资源内跳频发送PUSCH。
805、网络设备根据第一资源中的可用符号个数确定是否在第一资源内跳频接收PUSCH。
可选的，步骤804在具体实现时包括：终端在第一资源中的可用符号个数大于或等于第一阈值的情况下，使能跳频，即在第一资源内跳频发送PUSCH；终端在第一资源中的可用符号个数小于第二阈值的情况下，不使能跳频，即在第一资源内非跳频发送PUSCH。相应的，步骤805在具体实现时包括：网络设备在第一资源中的可用符号个数大于或等于第一阈值的情况下，在第一资源内跳频接收PUSCH；网络设备在第一 资源中的可用符号个数小于第二阈值的情况下，在第一资源内非跳频接收PUSCH。
其中，第二阈值小于或等于第一阈值。该可选的方法中的“大于或等于第一阈值”也可以替换为“大于第一阈值”，该情况下，“小于第二阈值”也可以替换为“小于或等于第二阈值”。“第一资源内非跳频”是指时隙内不跳频，时隙间可以跳频也可以不跳频。“第一资源内跳频”是指时隙内跳频，时隙间可以跳频也可以不跳频。
其中，PUSCH参数还可以配置跳频发送PUSCH。
可选的，PUSCH参数指示PUSCH的符号个数和/或DMRS占据的符号个数，第一阈值和/或第二阈值与PUSCH的符号个数和/或DMRS占据的符号个数有关。其中，PUSCH的符号个数可以为上述符号个数L。DMRS占据的符号个数越大时，第一阈值和/或第二阈值可以越大，PUSCH的符号个数越大时，第一阈值和/或第二阈值可以越大。第一阈值与第二阈值一般情况下是相同的。示例性的，若第一阈值和/或第二阈值仅与PUSCH的符号个数有关，第一阈值和/或第二阈值例如可以为
Figure PCTCN2021134624-appb-000004
或
Figure PCTCN2021134624-appb-000005
或
Figure PCTCN2021134624-appb-000006
等。若第一阈值和第二阈值仅与DMRS占据的符号个数有关，DMRS占据的符号个数为2，第一阈值和第二阈值可以为10，DMRS占据的符号个数为1，第一阈值和第二阈值可以为8。若第一阈值和第二阈值与PUSCH的符号个数和DMRS占据的符号个数有关，第一阈值和第二阈值例如可以为
Figure PCTCN2021134624-appb-000007
或
Figure PCTCN2021134624-appb-000008
S是指DMRS占据的符号个数。
第一阈值和/或第二阈值也可以为预设的，或，协议规定的，或，网络设备和终端协商确定的，或，网络设备指示的，本申请不作限制。若为网络设备指示的，网络设备可以通过RRC等配置信令或者DCI等指示信令将第一阈值和/或第二阈值通知给终端。
在步骤804中，不论第一资源中的可用符号个数为多少，终端最终都是要发送PUSCH的，区别仅在于是跳频发送PUSCH还是非跳频发送PUSCH。步骤804的一种可替换的实现方式为：终端根据第一资源中的可用符号个数确定是否在第一资源内发送PUSCH。该步骤在实现时，若PUSCH参数配置跳频发送PUSCH、且第一资源中的可用符号个数大于或等于(此处的大于或等于也可以替换为大于)第六阈值，则终端在第一资源内发送PUSCH，否则，终端不在第一资源内发送PUSCH；若PUSCH参数配置非跳频发送PUSCH、且第一资源中的可用符号个数大于或等于(此处的大于或等于也可以替换为大于)第七阈值，则终端在第一资源内发送PUSCH，否则，终端不在第一资源内发送PUSCH。在终端确定在第一资源内发送PUSCH的情况下，是否跳频发送PUSCH取决于PUSCH参数的配置。
其中，第六阈值可以大于第七阈值。例如，若将第六阈值记为Y2，第七阈值记为Y1，DMRS占据的符号个数记为S，则Y2＝Y1+S。第六阈值和/或第七阈值也可以为预设的，或，协议规定的，或，网络设备和终端协商确定的，本申请不作限制。
上述实施例中，关于S的取值可以为：若网络设备配置单符号DMRS(即一个DMRS占据1个符号)、且无额外的DMRS，则S＝1；若网络设备配置双符号DMRS(即一个DMRS占据2个符号)、且无额外的DMRS，则S＝2；若网络设备配置单符号DMRS、且有额外的DMRS，则S＝2；若网络设备配置双符号DMRS、且有额外的DMRS，则S＝4。
步骤804的可替换的实现方式规定了跳频和非跳频情况下，发送PUSCH的可用符号的下限。
在上述实施例中，终端确定在第一资源内跳频发送PUSCH之后，在一种实现方式中，终端跳频的位置可以与第一资源所属的时隙中的可用符号个数有关，例如，若该时隙中的可用符号个数为K，则跳频位置可以为K个可用符号中的第
Figure PCTCN2021134624-appb-000009
或
Figure PCTCN2021134624-appb-000010
个符号。在另一种实现方式中，终端跳频的位置可以与配置的符号个数L有关，例如，跳频位置可以为第一资源所属的时隙中的L个符号中的第

或

个符号。
需要说明的是，时域资源配置时存在特殊时隙，例如，下行转上行的时隙中，下行符号：灵活符号：上行符号的配比为10:2:2或者6:4:4。当N个时隙中存在特殊时隙时，在需要使用特殊时隙中的资源发送PUSCH的情况下，由于特殊时隙的上行符号位于特殊时隙的最后几个符号上，而TypeA对应的起始符号S＝0，因此，若采用TypeA对应的起始符号S和符号个数L确定特殊时隙中的资源，大概率会导致特殊时隙无法用于PUSCH的发送，造成资源的浪费。
因此，可以另外为特殊时隙直接或间接配置起始符号S和符号个数L，具体可以通过以下方式11至方式13中的任意一种方式实现。本申请中为了方便描述，将为特殊时隙配置的起始符号S(也可以描述为特殊时隙对应的起始符号S)记为S S，将为特殊时隙配置的符号个数L(也可以描述为特殊时隙对应的符号个数L)记为L S。
方式11、直接配置特殊时隙对应的起始符号S S和/或符号个数L S。
当仅配置S S时，表示从特殊时隙中的符号S S开始的可用符号均用于发送PUSCH；当仅配置L S时，表示从特殊时隙中的符号(14-L S)开始的L S个符号中的可用符号用于发送PUSCH；当既配置S S又配置L S时，表示从特殊时隙中的符号S S开始的L S个符号中的可用符号用于发送PUSCH。
方式12、配置特殊时隙对应的起始符号S S，以及特殊时隙对应的符号个数L S与下一个时隙中的上行符号个数之和(由于该符号个数与现有的符号个数含义不同，此处记为L2)。此时，
Figure PCTCN2021134624-appb-000014
例如，时隙n为特殊时隙，时隙n+1为上行时隙，终端根据S S和L2的值可以计算得到特殊时隙上发送PUSCH的符号个数。若S S＝10，L2＝18＝L S+14，在特殊时隙上，采用S S＝10，L S＝4发送PUSCH，上行时隙上，采用S＝0，L＝14发送PUSCH，若S S＝12，L2＝16＝L S+14，在特殊时隙上，采用S S＝12，L S＝2发送PUSCH，上行时隙上，采用S＝0，L＝14发送PUSCH。
方式13、在N个时隙上发送PUSCH或重复发送PUSCH时，配置起始时隙中的起始符号S，以及PUSCH资源的总符号个数(由于该符号个数与现有的符号个数含义不同，此处记为L3)。
若N个时隙中起始时隙为特殊时隙，其他时隙为上行时隙时，则配置的起始符号S即S S，L S＝14-S S。此时，L3＝(14-S S)+(N-1)*14。若网络设备未为终端配置N，则
Figure PCTCN2021134624-appb-000015
若N个时隙中起始时隙为特殊时隙，其他时隙包括上行时隙和另一个特殊时隙时，第一个特殊时隙对应的S S即配置的起始符号S，第一个特殊时隙对应的L S＝14-S S。此时，L3＝(14-S S)+(N-2)*14+L S2，L S2是指第二个特殊时隙对应的符号个数。若网 络设备未为终端配置N，则
Figure PCTCN2021134624-appb-000016
第二个特殊时隙对应的
Figure PCTCN2021134624-appb-000017
Figure PCTCN2021134624-appb-000018
第二个特殊时隙对应的起始符号为S S2＝14-L S2。
若N个时隙的除起始时隙之外的其他时隙中有一个时隙为特殊时隙，则L3＝(14-S)+(N-2)*14+L S。此时，若网络设备为终端配置了N，则可以确定则L S＝L3-(14-S)-(N-2)*14，若网络设备未为终端配置N，则
Figure PCTCN2021134624-appb-000019
L S＝L3-(14-S)-(N-2)*14，特殊时隙对应的起始符号为S S＝14-L S。
若N个时隙中起始时隙为特殊时隙，N个时隙中的其他时隙中的从起始符号S开始的L个符号用于发送PUSCH，则配置的起始符号S即S S，L S＝14-S S。此时，L3＝(14-S S)+L*(N-1)。若网络设备未为终端配置N，则
Figure PCTCN2021134624-appb-000020
若N个时隙的除起始时隙之外的其他时隙中有一个时隙为特殊时隙，N个时隙中的除特殊时隙之外的时隙中的从起始符号S开始的L个符号用于发送PUSCH，则L3＝(14-S)+L*(N-2)+L S。此时，若网络设备为终端配置了N，则可以确定L S＝L3-(14-S)-L*(N-2)，若网络设备未为终端配置N，则
Figure PCTCN2021134624-appb-000021
则L S＝L3-(14-S)-L*(N-2)，特殊时隙对应的起始符号为S S＝14-L S。
方式11和方式12可以使得终端确定S S和L S。方式13中，终端不仅可以确定S S和L S，还可以确定N，因此，在方式13中，网络设备可以不为终端配置N，通过L3间接指示N的值。
上述方式11至方式13在具体实现时，网络设备可以向终端发送配置信息，该配置信息用于配置特殊时隙对应的起始符号S S和/或符号个数L S，终端根据该配置信息确定特殊时隙对应的起始符号S S和/或符号个数L S。该配置信息配置的值可以为对应方式中配置的值。
上述方式11在具体实现时，可以单独为特殊时隙配置一个类似于表1的时域资源分配表，例如，在3GPP TS38.331中的PUSCH配置参数中新增参数“startSymbol_special_slot”配置特殊时隙对应的起始符号，新增参数“length_special_slot”配置特殊时隙对应的符号长度。方式12或方式13在具体实现时，若L2或L3大于14，则可以通过配置在表1中增加一行L的取值范围，该L的取值范围即方式12或方式13中配置的L2或L3的一些可能取值。
上述方式11至方式13中任一种方式中配置的值也可以配置在上述表2中，例如，通过RRC信令的配置在表2中增加一行(或多行)方式11至方式13中任一种方式配置的值。
可选的，PUSCH参数还用于指示特殊时隙对应的起始符号和/或符号个数。此时，在第一时隙为特殊时隙的情况下，终端可以根据PUSCH参数确定第一时隙对应的起始符号和/或符号个数。示例性的，在方式11至方式13中任一种方式中配置的值配置在上述表2中时，PUSCH参数中可以携带表2中的一个行索引，该行索引对应的参数可以直接或间接指示特殊时隙对应的起始符号和符号个数。
可选的，该方法还包括：网络设备向终端发送第一指示信息，第一指示信息用于指示所述第一资源中的DMRS位置，所述DMRS位置为所述第一资源中的第1个至第4个可用符号中的一个符号或多个符号(多个符号可以连续也可以不连续)，或者， 所述DMRS位置为所述第一资源中的倒数第3个符号和/或倒数第4个符号。相应的，终端接收来自于网络设备的第一指示信息。后续过程中，终端可以根据第一指示信息确定发送的PUSCH中DMRS的位置。
该可选的方法可以解决采用本申请中的方式发送PUSCH时，DMRS如何发送的问题。
现有技术中，在PUSCH重复发送时，若PUSCH映射类型为TypeA，通过参数“dmrs-TypeA-Position”配置每个时隙的第3个(“dmrs-TypeA-Position”配置的值为2)或第4个(“dmrs-TypeA-Position”配置的值为3)符号承载DMRS，由于特殊时隙的前几个符号可能为下行符号，这种配置不适用，因此需要重新定义特殊时隙中的DMRS的位置。该可选的方法还可以解决该问题。示例性的，可以有以下几种方式：
方式21、“dmrs-TypeA-Position”配置的值为2指示PUSCH资源的第3个符号用于发送DMRS，“dmrs-TypeA-Position”配置的值为3指示PUSCH资源的第4个符号用于发送DMRS。
方式22、“dmrs-TypeA-Position”配置的值为2指示PUSCH资源的第1个符号用于发送DMRS，“dmrs-TypeA-Position”配置的值为3指示PUSCH资源的第2个符号用于发送DMRS。
方式23、“dmrs-TypeA-Position”配置的值为2指示PUSCH资源的第2个符号用于发送DMRS，“dmrs-TypeA-Position”配置的值为3指示PUSCH资源的第3个符号用于发送DMRS。
方式24、dmrs-TypeA-Position”配置的值为2指示PUSCH资源的第3个符号用于发送DMRS，“dmrs-TypeA-Position”配置的值为3指示PUSCH资源的第4个符号用于发送DMRS。
实施例一提供的方法给出了跳频和可用符号之间的关联关系，终端可以根据时隙中的可用符号的个数确定是否跳频发送PUSCH，可以在符号个数较多的情况下跳频发送PUSCH，在符号个数较少的情况下非跳频发送PUSCH，从而提高资源利用率。
实施例一提供的方法中的PUSCH的映射类型可以为TypeA，也可以为TypeB。
实施例一提供的方法在具体实现时，终端可以确定N个时隙中的每个时隙中的每个资源，并根据每个资源中的可用符号个数确定是否在该资源内跳频发送PUSCH，终端也可以确定N个时隙中的部分时隙中的部分或全部资源，并根据每个资源中的可用符号个数确定是否在该资源内跳频发送PUSCH。其中，一个时隙中有可能有多个资源，确定每个时隙中的资源的方法与确定第一时隙中的第一资源的方法类似，不再赘述。
实施例一提供的方法，终端可以根据第一资源中的可用符号的个数确定是否在第一资源内跳频发送PUSCH，可以在符号个数较多的情况下跳频发送PUSCH，在符号个数较少的情况下非跳频发送PUSCH，从而提高资源利用率。
实施例二
跨多个时隙承载1个TB的方案目前仅仅在讨论阶段，具体如何实现跨多个时隙承载1个TB，存在以下两个问题：
问题1、由于跨多个时隙，PUSCH资源的符号个数大于14，而原有的S和L的组合中的L是小于或等于14的，因此，如何低开销地指示PUSCH资源中的符号个数或 者1个TB所跨的时隙的个数是一个待解决的问题。
问题2、由于1个TB跨多个时隙，那么如何确定发送对该TB经过信道编码后的数据的资源，即该数据的发送涉及到的资源放弃准则，需要进一步设计。类似的，重复发送对该TB经过信道编码后的数据时如何确定重复发送的资源，也需要进一步设计。
参见图13，实施例二提供的方法包括：
1301、网络设备向终端发送时隙格式和PUSCH参数。相应的，终端接收来自于网络设备的时隙格式和PUSCH参数。
步骤1301的相关描述可参见上述步骤801，区别仅在于，时域参数中不需要包括重复次数，在有些情况下，时域参数中也可以不包括对应起始符号S、符号个数L和K 2的一个索引。可参考进行理解，不再赘述。在时域参数中包括重复次数但是不包括用于指示时隙个数的信息的情况下，也可以将重复次数确定为时隙个数。
其中，PUSCH参数可以携带在RRC和/或DCI中。
其中，时域参数中可以包括用于指示时隙个数的信息，具体可以通过以下三种方式指示时隙个数。
方式31、在配置时域资源分配表(例如，上述表1或表2)时，额外配置TB覆盖的时隙个数，比如新增一个参数用于配置时隙个数N，该参数用于指示跨N个时隙承载TB。该情况下，N的取值通过PUSCH参数指示。
方式32、在配置时域资源分配表(例如，上述表1或表2)时，配置L为起始时隙中的用于发送的符号个数与14*(N-1)之和，此时的L由于与现有技术中不同，记为L1。例如，通过配置在表2中增加一行或多行，每行用于指示一个L1，每行中还可以配置一个S，用于指示起始时隙中的起始符号。例如，S＝8，L1＝32，则得到
Figure PCTCN2021134624-appb-000022
Figure PCTCN2021134624-appb-000023
即N＝3，起始时隙中的用于发送的符号长度为32-14*(N-1)＝4，即起始时隙中从起始符号S开始的4个符号用于发送数据。该情况下，L1可以是PUSCH参数指示的，N的取值根据PUSCH参数指示的符号个数L1确定。
方式33、在配置时域资源分配表(例如，上述表1或表2)时，配置L为起始时隙中的用于发送的符号个数与N-1之和，此时的L由于与现有技术中不同，记为L1。例如，通过配置在表2中增加一行或多行，每行用于指示一个L1，每行中还可以配置一个S，用于指示起始时隙中的起始符号。在方式33中，默认起始时隙中的起始符号S开始的符号均用于发送，则L1＝(N-1)+(14-S)，则通过L1可以计算得到N。例如，S＝8，L1＝8，起始时隙内用于发送的符号个数为14-S＝6，即起始时隙中的从S开始的6个符号用于发送数据，从而得到N-1＝L1-(14-S)＝2，则N＝3。该情况下，L1可以是PUSCH参数指示的，N的取值根据PUSCH参数指示的符号个数L1确定。
方式31相比方式32和方式33，需要额外引入参数指示N，方式32和方式33均无需引入额外的参数指示N，通过L1即可指示N。方式33假设起始时隙中的起始符号S开始的符号均用于发送，因此，方式33中的L1的取值范围要比方式32中的L1的小，从而可以节约一定的比特数。
另外，方式32和方式33中的L1也可以指示用于发送数据的PUSCH资源，例如， 方式32中的L1可以用于指示起始时隙中的从起始符号S开始的L1-14*(N-1)个符号用于发送数据，N个时隙中的第二个时隙至第N个时隙中的可用符号均用于发送数据，方式33中的L1可以用于指示起始时隙中的从起始符号S开始的可用符号均用于发送数据，N个时隙中的第二个时隙至第N个时隙中的可用符号均用于发送数据。可以理解的是，相比直接指示PUSCH资源中的符号个数，方式32和方式33所需的比特数更少，从而可以节约一定的比特数。
上述方式31至方式33在具体实现时，网络设备可以向终端发送配置信息，该配置信息用于配置N的值(对应方式31)或L1(对应方式32或方式33)，终端根据该配置信息确定N的取值或L1。该配置信息配置的值可以为对应方式中配置的值。
1302、终端根据PUSCH参数确定N个时隙。
步骤1302在具体实现时，在有些情况下，终端需要根据PUSCH参数和时隙格式确定N个时隙。
终端确定N个时隙的过程可参见实施例一，不再赘述。N个时隙也可以为实施例一中的情况(1)至情况(11)中的任一种。
1303、网络设备根据PUSCH参数确定N个时隙。
步骤1303在具体实现时，可参考步骤1302进行理解，区别仅在于，此处为网络设备。
步骤1303可以执行在步骤1302之后，也可以执行在步骤1302之前，本申请不作限制。
1304、终端根据N个时隙的时隙格式确定是否在N个时隙内发送PUSCH上承载的数据，在N个时隙内发送的数据是对TB进行信道编码得到的，TB的大小根据N个时隙中的可用符号确定。也就是说，该数据是基于N个时隙中的可用符号对TB进行信道编码的。TBS可以根据N个时隙中的可用符号个数、网络设备配置的用于发送PUSCH的RB个数以及DMRS的资源个数等信息确定。
在N个时隙内发送的数据可以是基于N个时隙中的全部可用符号对TB进行信道编码后的数据，也可以是基于N个时隙中的部分可用符号对TB进行信道编码后的数据。具体可参见实施例一中的相关描述，不再赘述。
步骤1304在具体实现时，可以通过以下几种方式实现：
方式41、在满足第一条件的情况下，在N个时隙内发送数据；否则，确定不在N个时隙上发送数据。第一条件为：N个时隙中的每个时隙的起始符号以及每个时隙的起始符号之后的符号均为可用符号。
方式42、在满足第二条件的情况下，在N个时隙内发送数据；否则，确定不在N个时隙上发送数据。第二条件为：N个时隙中的起始时隙中的从起始符号开始的符号均为可用符号、且N个时隙中的其他时隙中的符号均为可用符号(或者说起始符号以及起始符号之后的N*14-S个符号)。
方式43、在满足第三条件的情况下，在起始时隙内发送数据，否则，确定不在起始时隙上发送数据；在满足第四条件的情况下，在第i个时隙内发送数据，否则，确定不在第i个时隙上发送数据，i的取值为：2，…，N。其中，S为起始符号的索引，S由PUSCH参数指示。第三条件为：N个时隙中的起始时隙中的起始符号开始的符号 均为可用符号。第四条件为N个时隙中的第i个时隙中的符号均为可用符号。
方式44、在满足第五条件的情况下，在第i个时隙内发送数据，否则，确定不在第i个时隙上发送数据，i的取值为：1，2，…，N。第五条件为：N个时隙中的第i个时隙内存在的可用符号的个数大于或等于第三阈值。第五条件中的“大于或等于”也可以替换为“大于”。
方式45、在满足第六条件的情况下，在第i个时隙内发送数据，否则，确定不在第i个时隙上发送数据，i的取值为：1，2，…，N。第六条件为：N个时隙中的第i个时隙内存在可用符号。
上述方式41至方式45中的方式41和方式42为多时隙级别的规则，方式43和方式44为单时隙级别的规则，方式45为符号级别的规则。需要说明的是，对于方式41至方式45中的任意一种方式，若终端在确定N个时隙的过程中已经确定N个时隙满足相应方式对应的条件时，则在发送数据之前，不需要再进行相应条件的判断。
可选的，上述方式41至方式45中，终端还可以在满足相应方式对应的条件、且满足N个时隙中的可用符号的总个数大于或等于(此处的大于或等于也可以替换为大于)第八阈值的情况下，才发送数据。第三阈值和/或第八阈值可以为预设的，或，协议规定的，或网络设备和终端协商确定的，本申请不作限制。可以理解的是，若终端在满足一定的条件时发送数据，则网络设备也是在满足该条件时接收数据，为避免重复，不再赘述。
上述方式41至方式45中的各个条件也可以用于确定PUSCH资源。其中，在满足方式41、方式42或方式43中的条件的情况下，在每个时隙的从起始符号S开始的L个符号内发送数据，或者，在每个时隙的全部可用符号内发送数据，或者，在起始时隙的从起始符号S开始的L个符号、以及N个时隙中的其他时隙中的可用符号上发送数据，或者，在起始时隙的从起始符号S开始的全部可用符号、以及N个时隙中的其他时隙中的可用符号上发送数据。在满足方式44或方式45中的条件的情况下，若一个时隙的从起始符号S开始的L个符号均为可用符号，在该时隙的从起始符号S开始的L个符号内发送数据，或者，在该时隙的全部可用符号内发送数据，若该时隙的从起始符号S开始的L个符号中存在不可用符号，可以在该时隙的全部可用符号内发送数据。
可选的，若各个条件中S＝0或者未配置S，则可以认为N个时隙中每个时隙中的14个符号均为可用符号时，才可以用于发送数据；
1305、网络设备根据N个时隙的时隙格式确定是否在N个时隙内接收PUSCH上承载的数据，在N个时隙内发送的数据是对TB进行信道编码得到的，TB的大小根据N个时隙中的可用符号确定。
实施例二还提供了重复发送数据的起始时隙的确定方法，可选的，有以下几种情况：
情况1、N个时隙之后的第一个时隙为用于重复发送数据的起始时隙。例如，参见图14中的(a)，若N＝2，第一次发送数据从时隙n开始覆盖2个时隙到时隙n+1，重传从时隙n+2开始覆盖两个时隙到时隙n+3，再一次重传从时隙n+4开始覆盖两个时隙到时隙n+5。
情况2、N个时隙之后的第一个存在可用符号的时隙为用于重复发送数据的起始时隙。例如，参见图14中的(b)，若N＝2，第一次发送从时隙n开始覆盖2个时隙到时隙n+1，重传从下一个有可用符号的时隙开始，即时隙n+3开始覆盖两个时隙到时隙n+4，期间由于时隙n+2为下行时隙没有上行符号所以没有作为重传的开始时隙。
情况3、N个时隙之后的包含的可用符号的符号个数大于或等于(此处的大于或等于也可以替换为大于)第四阈值的第一个时隙为用于重复发送数据的起始时隙。其中，第四阈值可以为预设的，或，协议规定的，或，网络设备和终端协商确定的，本申请不作限制。
情况4、N个时隙之后的从起始符号开始的L个符号均为可用符号的第一个时隙为用于重复发送数据的起始时隙。实施例二提供的方法，解决了1个TB跨多个时隙的情况下，确定发送对该TB经过信道编码后的数据的资源的问题，以及如何低开销的指示PUSCH资源中的符号个数或者1个TB所跨的时隙的个数等问题，使得跨多个时隙承载1个TB的方案得以实现。
在实施例二所示的方法中，可选的，N个时隙中的每个时隙内是否跳频发送数据根据该时隙中的可用符号个数确定。相应的，N个时隙中的每个时隙内是否跳频接收数据根据该时隙中的可用符号个数确定。该可选的方法的具体实现与步骤805类似，将其中的第一资源替换为该时隙中的可用符号进行理解即可，不再赘述。
在实施例二所示的方法中，可选的，N个时隙中的第一个时间窗口内的时隙对应的频域位置为第一频域位置，第二个时间窗口内的时隙对应的频域位置为第二频域位置。第一个时间窗口与第二个时间窗口为时域上相邻的时间窗口。第一频域位置与第二频域位置不同。N个时隙中可以有2个时间窗口，也可以有更多个时间窗口。
其中，时间窗口的大小可以是网络设备通过RRC信令配置给终端的，时间窗口的大小与信道特征有关，例如，时间窗口可以包括K个时隙，则在K个时隙中用于承载PUSCH的时隙上发送数据时，数据位于同一个频域位置。K可以为大于1的整数。该可选的方法中，由于多个时隙上的信道特征一般具有相关性，因此，以时间窗口作为时隙间跳频的单位，可以提高信道的检测性能。
实施例二提供的方法，终端根据PUSCH参数确定N个时隙，并根据N个时隙的时隙格式确定是否在N个时隙内发送PUSCH上承载的数据，从而在N个时隙内可以发送PUSCH上承载的数据的情况下，在N个时隙上发送PUSCH，实现跨多个时隙承载1个TB。另外，实施例二还提供了低开销的指示PUSCH资源中的符号个数的方法、确定用于发送数据的PUSCH资源的方法以及确定重复发送数据的起始时隙的方法，从而保证了跨多个时隙承载1个TB的方案的实现。
其中，若将实施例一和实施例二中的方案作为一个整体的方案，可以认为是终端和/或网络设备根据时隙格式和PUSCH参数确定第一信息，第一信息为实施例一中的第一时隙中的第一资源或实施例二中的N个时隙。若确定第一信息为实施例一中的第一时隙中的第一资源，则本申请提供的方案的具体的实现过程可参见实施例一，若确定第一信息为实施例二中的N个时隙，则本申请提供的方案的具体的实现过程可参见实施例二。
实施例三
参见图15，实施例三提供的方法包括：
1501、终端确定N个时隙，N个时隙用于发送PUSCH或用于重复发送PUSCH。
步骤1501的具体实现可参见实施例一，不再赘述。N个时隙可以为实施例一中的情况(1)至情况(11)中的任一种。
在步骤1501之前，该方法还可以包括上述步骤1301，以便终端执行步骤1501。
1502、网络设备确定N个时隙。
步骤1502在具体实现时，可参考步骤1501进行理解，区别仅在于，此处为网络设备。
1503、终端在N个时隙上发送PUSCH或者重复发送PUSCH。相应的，网络设备在N个时隙上接收PUSCH或者接收PUSCH的重复。
实施例三中的相关概念的解释以及相关步骤的实现可以参见上述实施例一和实施例二，为避免重复，此处不再赘述。
实施例三提供的方法，在通过跨多个时隙承载1个TB或在多个时隙内重复发送PUSCH提高PUSCH的覆盖范围的情况下，可以确定这多个时隙，从而使得这些方案得以顺利实现。
本申请上文中提到的各个实施例之间在方案不矛盾的情况下，均可以进行结合，不作限制。本申请各个附图中所示的时隙之间(例如，图1中的时隙n+2和时隙n+3)之间可能存在下行时隙，由于本申请不涉及在下行时隙上发送数据，因此，在附图中并未示出，但应理解，本申请附图中示出的各个时隙均为举例，并不是对实际实现时的时隙格式以及时隙位置的限定。本申请上述实施例中的PUSCH参数在指示起始符号S、符号个数L和K 2时，也可以不是指示一个索引，而是直接指示起始符号S、符号个数L和K 2中的一个或多个，本申请不作限制。
本申请的主要发明点概述：
本申请给出了一种PUSCH Type A方式重复传输的增强方法：
实施例1：1个时隙内Type A增强方案，基于是否跳频设计可用资源的放弃准则，或者根据可用资源数量确定是否跳频。
实施例2：1个TB跨多时隙的Type A重复传输方案，设计放弃准则，粒度包括多时隙级别、时隙级别、符号级别等。
实施例3：指示实施例1和实施例2所述的增强方案时，配置新TDRA表格，在RRC配置时，配置新的TimeDomainAllocationList，在高层配置了信令后，DCI中指示新的TimeDomainAllocationList的某一行，区别是L>14，并且定义其含义。
本申请实施例1：可用资源与时隙内跳频的关联。
核心思想：根据是否跳频得到可用资源的下限用于放弃准则，或者根据可用资源的符号数决定传输PUSCH时是否跳频。
可用符号：包括上行符号以及部分灵活符号，不含下行符号，以及下行符号之后的用于下行转上行切换的符号。
准则1：当配置时隙内不跳频时，如果从起始符号(S)开始的L个中可用符号大于或等于Y1，在该时隙传输PUSCH；当配置时隙内跳频时，如果从起始符号(S)开始的L个中可用符号大于或等于Y2，在该时隙传输PUSCH，Y2>Y1。
可选的，Y2＝Y1+DMRS符号数，比如配置单符号DMRS，且无额外的DMRS，Y2＝Y1+1；如配置双符号DMRS，且无额外的DMRS，Y2＝Y1+2；配置单符号DMRS，有1个额外的DMRS，Y2＝Y1+2；配置双符号DMRS，且有额外的DMRS，Y2＝Y1+4。
准则2：当配置PUSCH的符号数L且配置了时隙内跳频时，若一个时隙内可用符号数小于一个门限值X，则不使能时隙内跳频，即在该时隙内传输PUSCH时不进行时隙内跳频；若一个时隙内可用符号数大于或等于门限值X，则在该时隙传输PUSCH时使能时隙内跳频。
可选的，门限值X和L有关，比如
Figure PCTCN2021134624-appb-000024
或
Figure PCTCN2021134624-appb-000025
或
Figure PCTCN2021134624-appb-000026
具体门限值可以通过RRC等配置信令或者DCI等指示信令承载通知终端。
除了是否使能跳频，实施例1的一个次要发明点在于DMRS位置的确定。现有的Type-A repetition是通过参数dmrs-TypeA-Position配置整个时隙的第3个(pos2)或第4个(pos3)符号承载DMRS，由于特殊时隙的前几个符号可能未下行符号，这种配置不适用，因此需要重新定义DMRS的位置。
方式1：pos2或pos3指示该PUSCH的第3个或第4个符号。
方式2：pos2或pos3指示该PUSCH的第1个或第2个符号，或者第2个或第3个符号。
方式3：pos2或pos3指示该PUSCH的倒数第3个或倒数第4个符号。
本申请实施例1的技术效果：本申请提出的方案给出了时隙内跳频和可用资源之间的关联关系，通过可用资源来确定是否时隙内跳频或者根据时隙内跳频来确定可用资源的承载PUSCH的下限。
本申请实施例1区别于现有技术的改进之处：本申请提出的方案和现有技术中Type-A的方式相比对于资源的要求更灵活，但仍限制在1个时隙内，相比Type-B的方式减少了跨时隙带来的资源零散问题。
本申请实施例2：1个TB覆盖多个时隙的重复放弃准则。
核心思想：给出了1个TB覆盖N个时隙进行重复的放弃准则，包含多时隙级、单时隙级和符号级，从而给出了可用资源的确定方法(N>1)，需要说明的是，这些放弃准则也可以用于1个TB覆盖N个时隙时确定可用资源。
在1个TB覆盖N个时隙时(N>1)，资源的确定包含以下两部分，一部分是起始时隙的位置，另一个部分是起始时隙开始的多个时隙内可用资源包含那些符号。
首先，起始时隙的确定：
对于首次传输，根据DCI的指示信息所在的时隙以及RRC或DCI中指示的间隔时隙个数，得到首次传输起始时隙位置。对于之后的重传，有以下两种方式确定起始时隙：
第一种方式类似Type A，上一次传输之后的第一个时隙计为起始时隙；
第二种方式类似Type B，上一次传输之后的第一个出现可用符号的时隙或者该时隙可以承载PUSCH的第一个时隙时，该时隙计为起始时隙(推荐)；
举例如图14中的(a)和图14中的(b)所示，第一种方式(对应图14中的(a))的第一次传输从时隙n开始覆盖2个时隙到时隙n+1，重传从时隙n+2开始覆盖两个时隙到时隙n+3，再一次重传从时隙n+4开始覆盖两个时隙到时隙n+5。第二种方式 (对应图14中的(b))的第一次传输从时隙n开始覆盖2个时隙到时隙n+1，重传从下一个有可用资源的时隙开始，即时隙n+3开始覆盖两个时隙到时隙n+4，期间由于时隙n+2为全下行时隙没有上行符号所以没有作为重传的开始时隙。
在确定了每次传输覆盖的N个时隙所在的范围，进一步确定其中的可用资源有哪些。
方式1：多时隙级别放弃准则
当N个时隙中不满足第一个时隙中S起始符号为可用符号，S符号之后的符号均为可用符号时或者S符号之后的N*14-S个符号均为可用符号，放弃该PUSCH重复传输；若S＝0或者未配置S，则N个时隙均以14个符号均为可用符号时才能承载该PUSCH重复传输。
方式2：单时隙级别放弃准则
起始时隙中S符号为可用符号，且该时隙内S符号之后的14-S个符号为可用符号时才传输；起始时隙之后的时隙，14个符号均为可用符号时才用于传输；
若S＝0或者未配置S，则每个时隙均以14个符号均为可用符号为标准确定作为传输资源。
方式3：符号级别放弃准则
除了下行符号以及下行符号后的用于收发转换的灵活符号外，其余符号纳入可用符号，用于传输PUSCH。
本申请实施例2的技术效果：本申请提出的方案给出了1个TB覆盖多个时隙时确定资源的方法，包括起始时隙的确定，时隙内资源的确定等。
本申请实施例2区别于现有技术/实施例1的改进之处：现有技术未有1个TB覆盖多个时隙的可用资源确定方法，本实施例补齐了这种缺失。
本申请实施例3：增强方法的指示。
核心思想：现有技术通过TDRA表格配置S和L，但对于实施例1和实施例2均不适用，因为实施例1涉及的特殊时隙中S不再是0，而实施例2中L不再仅限于14个符号内，本实施例通过配置新的TDRA表格，分别适用于上述两种实施例。
38.331中PUSCH配置表格如下：
Figure PCTCN2021134624-appb-000027
Figure PCTCN2021134624-appb-000028
实施例1的指示方法：
对于实施例1的方案，一种方式1，在配置RRC表格时，额外配置特殊时隙所用的起始符号和/或符号长度，比如新增startSymbol_special_slot，或者length_special_slot，用来指示特殊时隙中承载PUSCH的资源位置。
当仅配置了startSymbol_special_slot时，表示从startSymbol_special_slot开始的所有上行或灵活符号均用来传输PUSCH；当仅配置了length_special_slot时，表示从14-length_special_slot对应的那个符号开始，一直持续length_special_slot达到时隙结束位置中间的length_special_slot个符号用于承载PUSCH；当既配置了startSymbol_special_slot又配置了length_special_slot时，表示从startSymbol_special_slot开始，持续length_special_slot个符号用于承载PUSCH。
对于实施例1的方案，另一种配置方式2是在重复方式为TypeA的情况下，配置startSymbol2和length2，此时startSymbol2为一个时隙中起始符号，该时隙中持续符号长度为min(length2-startSymbol2,14)，对于剩余的length2-min(length2-startSymbol2,14)，即为在特殊时隙中的符号长度，起始位置从特殊时隙的末尾开始，向前包含length2-min(length2-startSymbol2,14)个符号。
对于实施例1的方案，还有一种配置方式3，startSymbol3指示特殊时隙中起始符号位置，L标识为特殊时隙的符号长度加上下一个时隙中的上行符号数。例如startSymbol3＝10,L＝4+14＝18，在其余的UL时隙上，UE理解为startSymbol＝0,L＝14，而在第一个时隙上，采用startSymbol3＝10,L＝4传输PUSCH；startSymbol3＝12,L＝2+14＝18，在其余的UL时隙上，UE理解为startSymbol＝0,L＝14，而在第一个时隙上，采用start＝12,L＝2传输第一次。
实施例2的指示方法：
对于实施例2的方案，一种方式a，在配置RRC表格时，额外配置覆盖的时隙个数，比如新增一个参数时隙个数N，用来指示跨N个时隙承载1个TB。
对于实施例2的方案，另一种方式b，在配置RRC表格时，配置L为初始时隙内从S开始的符号个数加上14*(N-1)，其中N为所述跨N个时隙承载1个TB。
例如S＝8，L＝32，则得到
Figure PCTCN2021134624-appb-000029
即N＝3，第一个时隙内符号长度为32-14*(N-1)＝4，即第一个时隙中从S开始的4个符号承载PUSCH。
对于实施例2的方案，还有一种指示方式c，在配置RRC表格时，配置L为初始时隙内从S开始的符号个数加上(N-1)，其中N为所述跨N个时隙承载1个TB。由于通过S知道首个时隙内的起始符号位置，在首个时隙从S开始符号均用于承载PUSCH，得到首个时隙中可用符号数为14-S，从而根据L得到(N-1)的值，即可知1个TB覆盖的时隙个数N。
例如S＝8，L＝8，第一个时隙内符号长度为14-S＝6，即第一个时隙中从S开始的6个符号承载PUSCH，从而得到N-1＝L-(14-S)＝2，即N＝3。
可以看出方式a需要额外引入参数，方式b和方式c均无需引入新的参数，但是方式c通过假设第一个时隙内从S开始的符号均为可用资源，导致方式c的L取值范围要比方式b的小，从而可以节约一定的比特数。
本申请实施例3的技术效果：本申请提出的方案给出了如何指示实施例1和实施例2涉及的PUSCH传输所占的资源位置。
本申请实施例3区别于现有技术/实施例1的改进之处：与现有技术相比，实施例3给出了特殊时隙的指示或者计算方法和/或1个TB覆盖N个时隙时的N的指示或者计算方法。
