Description

信息发送的方法和装置
本申请要求于2021年5月11日提交中国国家知识产权局、申请号为202110513676.0、发明名称为“信息发送的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且，更具体地，涉及一种信息发送的方法和装置。
背景技术
为了提升覆盖性能，通过跨多时隙传输块(transport block over multi-slot，TBoMS)技术，将多个时隙上的小数据包聚合成一个大数据包，并在多个时隙上共同传输聚合后的数据包。进一步地，为了实现TBoMS的资源映射，可以复用重复的资源映射机制，即冗余版本(redundantversion，RV)循环机制，通过RV来指示循环缓存中一个传输时机携带的编码比特。由于在使用重复的资源映射机制时，一个传输块(transport block，TB)只包括一个时隙上的数据包，因此在相同数量的时隙上，使用TBoMS技术时的传输块大小(transport block size，TBS)要远大于使用重复的资源映射机制时的TBS。从而，在进行TBoMS的资源映射时，很可能出现信息比特不能完整地映射到时频资源的情况，从而导致解调性能下降。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：第五代(5th generation，5G)系统或新无线(new radio，NR)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)等。此外，本申请实施例的技术方案还可以应用于侧链路通信。例如，本申请实施例的技术方案还可以应用于：设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车联网系统中的通信。
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无线通信系统100的一示意图。如1图所示，该无线通信系统100可以包括至少一个网络设备，
如图1所示的网络设备111，该无线通信系统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。网络设备和终端设备均可配置多个天线，网络设备与终端设备可使用多天线技术通信。
其中，网络设备和终端设备通信时，网络设备可以管理一个或多个小区，一个小区中可以有整数个终端设备。可选地，网络设备111和终端设备121组成一个单小区通信系统，不失一般性，将小区记为小区#1。网络设备111可以是小区#1中的网络设备，或者说，网络设备111可以为小区#1中的终端设备(例如终端设备121)服务。
需要说明的是，小区可以理解为网络设备的无线信号覆盖范围内的区域。
本申请实施例中提到的发送端设备可以为终端设备，接收端设备可以为网络设备。例如，发送端设备为终端设备121，接收端设备为网络设备111。
应理解，上述图1仅是示例性说明，本申请并未限定于此。例如，本申请实施例还可以应用于需要重复发送数据(或者说数据块)的任何通信场景。
还应理解，该无线通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved node B，或home node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control， RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
还应理解，该无线通信系统中的终端设备也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
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。
2、跨多时隙传输块(transport block over multi-slot，TBoMS)
与LTE和长期演进高级(long term evolution advanced，LTE-A)无线通信系统相比，NR无线通信系统部署的频段更高，以获取更大的通信带宽。然而，高频段会导致更大的路径损耗和穿透损耗，使得NR的覆盖性能远不如LTE和LTE-A。
为了提升NR的覆盖性能，提出跨多时隙传输块技术。示例性地，如图2所示，将TB#1至TB#4聚合成一个大的TB。该技术将每个时隙上的小数据包聚合成一个大数据包，并在多个时隙上共同传输聚合后的数据包，通过减少TB切分次数，从而减少循环冗余码(cyclic redundancy code，CRC)的开销，通过增加传输块大小(transport block size，TBS)，从而提高编码增益，并通过降低频率资源，提高功率谱密度，提升覆盖性能。
3、传输时机(transmission occasion，TO)
一个传输时机由多个连续的时域符号组成。作为一个示例，如图4所示的时域资源中包括下行(downlink，DL)时隙(slot)，特殊(special，S)时隙，上行(uplink，UP) 时隙。DL时隙中包括14个DL符号(symbol)，UL时隙中包括14个UL符号，S时隙中包括6个DL符号，2个无效(invalid)符号，6个UL符号。图4中的时域资源的帧结构不对称，因此每个传输时机包括的上行时域符号数可能不同，当时域资源的帧结构对称时，每个传输时机包括的上行时域符号数相同。一个传输时机可以包括一个或多个时隙，或者，也可以包括一个时隙和几个时域符号，或者，也可以包括多个时隙和几个时域符号。
4、类型A(type A)和类型B(type B)的重复发送
如前所述，在一些场景下，如一些深覆盖场景，如小区边沿，或者地下室等，无线信号传播的路径损耗非常严重。为了改善上行传输性能，一种增强覆盖性能的方法是重复发送数据块。例如，终端设备重复发送PUSCH，网络设备对重复发送的数据块进行合并检测。通过该方式可以提升信道估计性能，提升数据解调性能，从而提升小区覆盖能力。
以当前的NR协议为例，在当前的NR协议中支持对PUSCH最大16次的重复发送，支持对PUCCH最大8次的重复发送。当前NR协议对PUCCH支持type A的重复发送，对PUSCH支持type A和type B的重复发送。
(1)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，配置一次重复发送在一个slot中需要占用的时域符号的起始位置和总长度，N个slot中，满足一次重复发送占据的时域符号的起始位置和总长度与配置的起始位置和总长度相同的slot，可以实际用于一次重复发送。其中，N为大于或等于1的整数。
(2)type B的重复发送
type B的重复发送，指示是：N次重复发送，依据第1次重复发送的起始时域符号位置S，按照每次重复需要占据的时域符号数目L，在连续的多个时域符号上进行重复发送。即从调度的第一个slot的第S个时域符号开始，后续的N*L个时域符号(可能会到延伸到其他的slot上)均用于N次重复发送。
应理解，关于type A和type B的重复发送的具体描述可以参考现有的协议，其对本申请实施例的保护范围不造成限定。
下文为方便描述，将type A的重复发送方式记为重复type A(repetition typeA)，将type B的重复发送方式记为重复type B(repetition type B)。
5、冗余版本(redundancy version，RV)
信息比特串在通过物理天线发出去之前，一般会经历一些信号处理过程，如图3所示。
信道编码：通过对信息比特串中引入冗余和校验比特，使得信号在到达接收端之后，接收端能够依据收到的多个比特(包括信息比特和校验比特)彼此之间的校验关系，能够较好的恢复出信息比特串。对于数据信道而言，目前NR可以支持低密度奇偶校验码(low density parity check code，LDPC)的信道编码。例如，对于100比特(bit)的信息比特串，通过1/5编码码率的LDPC编码，变成了500bit的编码后比特串，引入了400bit的冗余，信息比特串和编码后比特串长度的比值等于编码码率1/5。为区分，将编码后的比特串记为编码后比特串。
速率匹配：信息比特串传输经过信道编码得到较长的编码后比特串之后，并不是直接将所有的编码后比特串都发出去。一般地，终端设备可以按照网络设备指示给终端配置的可用的资源元素(resource element，RE)个数及调制阶数来确定能够发送多少比特，进而 从编码后比特串中进行选择(当前协议规定了4个起点，近似均匀的分布在编码后比特串中，分别标记为RV0，RV1，RV2，RV3)。
例如，当前1个资源块(resource block，RB)中的可用RE数目＝12*12＝144，采用正交相移键控(quadrature phase shift keying，QPSK)调制，则1个物理资源块(physical resource block，PRB)中能够承载144*2＝288bit。因此，需要从500比特的编码后比特串中选择出288比特，作为选择出的比特串，然后对该选择出的比特串进行调制和资源映射等处理。此时，对应的编码码率＝信息比特串/选择出的比特串长度＝100/288。
更具体地，速率匹配包括比特选择和比特交织。比特选择是指根据RV指定的起点从循环缓存中选择编码比特，选择的编码长度由被映射的时频资源大小决定的。比特交织是将选择出的比特进行行列交织，所以比特交织粒度与比特选择粒度一致，可以统称为速率匹配的粒度。
示例性的，如果被映射的时频资源是一个TO包括的时隙，那么选择的编码比特的长度就是一个TO上的时频资源(不考虑码块分割)，也可以理解为，速率匹配的粒度是一个TO。具体地，如果不考虑码块分割，选择的编码比特的长度就是被映射的时频资源大小，可以用公式表示为：N TO＝N RE·Q·ν，其中，N TO为一个传输时机的时频资源可以承载的比特数，Q为调制阶数，ν为层数。
6、将RV循环机制复用到TBoMS的资源映射
下面以重复type A为例，介绍目前将RV循环机制复用到TBoMS的资源映射的方案。
假设调度物理上行共享信道(physical uplink shared channel，PUSCH)的下行控制信息(downlink control information，DCI)指示的RV为rv id。对于基于重复类型A的时域资源分配(time domain resouce allocation，TDRA)的TBoMS，PUSCH的第n个传输时机使用的RV如表1所示。其中，一个传输时机定义为一个时隙。应理解，RV更新粒度为一个传输时机，即每一个传输时机都要更新使用的RV，更新顺序由RV序列决定，RV序列默认为{0,2,3,1}，即RV按照{0,2,3,1}顺序进行循环更新，循环的起点由调度PUSCH的DCI指示的rv id确定。另外，如果高层信令配置了RV序列指示信息repK-RV，则按照repK-RV指示的顺序更新RV。对于基于重复类型B的TDRA的TBoMS，PUSCH的第n次实际重复使用的RV如表1所示。其中，实际重复是名义重复被时隙边界、无效符号切分后得到的，名义重复是基站直接配置的，例如起点和长度指示值(start and length indicator value，SLIV)，重复次数K等参数。
表1 重复的资源映射机制

RV用于指示循环缓存中一个传输时机携带的编码比特。详细地说，经过低密度奇偶校验(low density parity check，LDPC)编码后的数据保存在循环缓存中，称作编码比特；每次传输根据rv id确定RV起点，记作k 0；从循环缓存的k 0处依次选取编码比特，映射至 一次传输时机的时频资源上，直到时频资源用完为止。其中，RV起点共有4个，分别用rv id＝0，rv id＝1，rv id＝2和rv id＝3指示，并分别记作RV0，RV1，RV2和RV3，每个RV起点k 0与LDPC编码使用的基图(basic grapy，BG)有关，如表2所示，其中N cb表示编码比特长度，Z C表示LDPC编码的扩展因子。
表2 RV起点位置k 0

示例性的，图5给出调度PUSCH的DCI指示rv id＝0、跨4个时隙的TBoMS的资源映射结果。如图5中的(a)所示，圆环表示循环缓存，存储信息比特经过信道编码之后得到的编码后比特串序列，RV0至RV3的位置根据表2确定；如图5中的(b)所示，为基于重复类型A的TDRA的资源映射结果，按照RV序列{0,2,3,1}的顺序将编码比特依次映射至4次传输时机的时频资源。
重复的资源映射机制，即RV循环机制，一个TB只包括一个时隙上的数据包，而一个TBoMS是多个时隙上数据包的聚合结果。在相同数量的时隙上，TBoMS的TBS要远大于重复的TBS，很容易出现信息比特无法完整发送的问题，从而导致解调性能降低。
示例性地，如图6所示，圆环表示循环缓存，该循环缓存用于存储信息比特经过信道编码之后得到的编码后比特串序列，圆环中的空白部分为编码后的校验比特，圆环中的阴影部分为编码后的信息比特。RV0,1,2,3为该编码后比特序列的近似4等分的位置点，当采用RV循环{0,2,3,1}的方式进行发送时，即不同时隙传输的比特从不同RV起点进行选择(选择出一定长度的比特序列)进行映射和发送。需要说明的是，本申请中的循环缓存存储的编码后比特串序列为“第一比特序列”，本申请中提及的“循环缓存”本质上是指“第一比特序列”，例如，“循环缓存中的第一个比特”本质上是再说“第一比特序列中的第一个比特”。
以图6为例，PUSCH#0内的资源假设能承载100比特，则从编码后比特序列中从RV0的位置开始选择连续的100比特进行发送；PUSCH#1内的资源假设能够承载100比特，则从编码后的比特序列中从RV2的位置开始选择连续的100比特进行发送；PUSCH#2内的资源假设能承载100比特，则从编码后比特序列中从RV3的位置开始选择连续的100比特进行发送；PUSCH#3内的资源假设能够承载100比特，则从编码后的比特序列中从RV1的位置开始选择连续的100比特进行发送。
由于PUSHC#0只能携带部分信息比特，其它PUSCH携带校验比特，当PUSCH#0能够承载的比特数小于循环缓存中信息比特的长度时，就会导致时域资源(PUSCH#0至PUSCH#3)无法承载完整的信息比特，导致解调性能下降。
理论分析如下，假设TBoMS的资源映射机制为基于重复Type A的TDRA，编码码率 为R，调制阶次为Q，层数为v，一个传输时机上分配给PUSCH的RE数量为N RE，时隙数为K，可得信息比特数为N info＝N RE·Q·R·ν·K，一个传输时机的时频资源可以承载的比特数为N TO＝N RE·Q·ν。如果等效码率R·K>1，则信息比特无法被一个传输时机的时频资源完整承载，导致解调性能下降。

S402b，终端设备根据第一资源与网络设备传输SRS，根据第三资源与网络设备传输TBoMS，第三资源为所述第二资源中除与所述第一资源在同一个时隙的资源以外的资源。

S402c，终端设备根据第一资源与网络设备传输SRS，终端设备根据第四资源与网络设备传输TBoMS，第四资源为第二资源中时序在所述第一资源之前的资源。
示例性地，当第四指示信息指示第一个时隙(即S时隙)的后四个OFDM符号以及后面两个时隙(均为UL时隙)用于传输TBoMS，第五指示信息指示第二时隙的后4个OFDM符号用于传输SRS，当终端设备执行S402时，如图9中的(d)所示，SRS占用了三个时隙中的第二个时隙的最后4个OFDM符号，时序在该4个OFDM符号以后的OFDM符号作为非法符号(即图9中的(d)中的第三个时隙)，不传输TBoMS，第四指示信息指示的除该第三个时隙、第二个时隙的最后4个OFDM符号外的资源仍用于传输TBoMS。可选地，第三个时隙也可以用于传输其他信号。
S402d，终端设备根据第一资源与网络设备传输SRS，终端设备不传输TBoMS。
示例性地，当第四指示信息指示第一个时隙(即S时隙)的后四个OFDM符号以及后面两个时隙(均为UL时隙)用于传输TBoMS，第五指示信息指示第二时隙的后4个OFDM符号用于传输SRS，当终端设备执行S402时，如图9中的(e)所示，SRS占用了三个时隙中的第二个时隙的最后4个OFDM符号，第四指示信息指示的除该4个OFDM符号之外的资源，不传输TBoMS。可选地，第四指示信息指示的除该4个OFDM符号之外的资源也可以用于传输其他信号。
本申请实施例，当传输TBoMS PUSCH与SRS的资源冲突时，即TBoMS PUSCH与SRS占用相同的资源时，在该资源上优先传输SRS，减少了TBoMS PUSCH与SRS的资源的冲突；其中S402a中的实现方式花费的代价和开销最小。

网络设备根据BG、调制和编码方案(modulation and coding scheme，MCS)表和MCS 索引确定所述资源映射参数，所述资源映射参数包括时隙数K，RV指示信息rv id和RV序列指示信息repK-RV。
应理解，本申请中，对于重复Type A的情况，一个传输时机定义为一个时隙，因此以重复Type A为例的可能的实现方式中，例如可能的实现方式一中，所涉及的“时隙数”即为MCS表中的“传输时机数”。
MCS表如下表3至表7所示，每个MCS表中均涉及MCS索引、调制阶数Q、目标码率、谱效率和传输时机数集合A以及传输时机数集合B。需要说明的是，PDSCH的MCS表是上下行通用的。
在对信息比特进行LDPC编码时采用如表2所示的LDPC BG1或LDPC BG2时，可以根据MCS索引指示，从MCS表(本申请中的表3至表7)中选择对应的传输时机数集合A，随后在该传输时机数集合A中确定出时隙数K。
示例性的，MCS表为PDSCH的MCS索引表1，即表3，MCS索引为3，则网络设备确定传输时机数集合A为{1,2,3,4}，则上述时隙数K的取值应当是{1,2,3,4}中的一个。
应理解，可能的实现方式一中的传输时机数集合A中包括的K满足第一条件：R·K≤1。其中，R为编码码率。由于信息比特数为N info＝N RE·Q·R·ν·K，一个传输时机的时频资源可以承载的比特数为N TO＝N RE·Q·ν，则当满足第一条件时，N info≤N TO，那么信息比特能够被一个传输时机的时频资源完全承载。当R一定时，根据第一条件可以确定出满足条件的K。

S502，网络设备向终端设备发送资源映射参数，相应地，终端设备接收来自网络设备的资源映射参数，该资源映射参数中包括时隙数K。
可选地，网络设备可以通过高层信令或者DCI发送资源映射参数。
S503，终端设备根据资源映射参数将编码比特映射到上行传输的时频资源。
终端设备根据已知的编码码率R和网络设备发送的时隙数K的乘积小于第一切换门限μ时，即R·K≤μ时，终端设备使用第一资源映射机制进行资源映射。当R·K≥μ时，终端设备使用第二资源映射机制进行资源映射。示例性地，当LDPC编码使用BG1时，μ可以是集合

图11中的(c)示出了终端设备使用第一资源映射机制时的示意图。第一资源映射机 制，即RV循环机制，以所述RV指示信息rv id为RV循环起点，所述RV序列指示信息repK-RV为RV循环顺序，RV更新粒度为一次传输时机，从循环缓存中对应位置将编码比特取出并映射至对应的传输时机上的时频资源。例如，如图11中的(c)所示，以rvid＝0为起点，将RV0、RV1、RV2、RV3分别映射到一个传输时机上。
图11中的(d)示出了终端设备使用第二资源映射机制时的示意图。第二资源映射机制，即连续资源映射机制，从循环缓存中的第一个编码比特开始将编码比特取出，映射到K个传输时机的时频资源上，RV不进行更新。例如，如图11中的(d)所示，以rv id＝0为起点，将RV0映射到一个TBoMS的传输时机上。
需要说明的是，该第二资源映射机制以所有传输时机为粒度进行速率匹配，换句话说，该第二资源映射机制是以整个TBoMS为粒度进行速率匹配。同样，第二资源映射机制比特交织的粒度也是所有传输时机或整个TBoMS。
S504，终端设备在上行传输的时频资源上向网络设备发送上行信号；相应地，网络设备在上行传输的时频资源上接收来自终端设备的上行信号。
需要说明的是，可能的实现方式一中，当网络设备执行S501时，本申请对于终端设备执行的资源映射的方法不做限定，终端设备执行的S503可以替换为现有的各种资源映射的方法；当终端设备执行S503时，本申请对应网络设备执行的确定传输时机数的方法不做限定，网络设备执行的S501可以替换为现有的各种确定传输时机数的方法。
本申请实施例，编码码率与传输时机数的乘积小于或等于1时，可以使得编码后比特序列中的信息比特能够被一个传输时机完全承载。网络设备通过编码码率确定出满足条件的传输时机数的集合，从该集合中确定传输时机数，发送给终端设备，终端设备根据该传输时机数进行资源映射时，能够使得信息比特完整地映射到时频资源上进行传输，提高解调性能。
下面以每个时隙分配的时域资源一致为例，结合图12，介绍可能的实现方式二。
S501，网络设备确定上行传输的资源映射参数。
网络设备根据BG、调制和编码方案(modulation and coding scheme，MCS)表和MCS索引确定所述资源映射参数，所述资源映射参数包括时隙数K，RV指示信息rv id和RV序列指示信息repK-RV。
应理解，本申请中，对于重复Type A的情况，一个传输时机定义为一个时隙，因此该可能的实现方式一中，所涉及的“时隙数”即为MCS表中的“传输时机数”。
在对信息比特进行LDPC编码时采用如表2所示的LDPC BG1时，可以根据MCS索引指示，从MCS表(本申请中的表3至表7)中选择对应的传输时机数集合B，随后在该传输时机数集合B中确定出时隙数K，同时，约束RV指示信息rv id和RV序列指示信息repK-RV，使得RV0和RV1必须分别映射到至少一个传输时机的时频资源上。
示例性的，MCS表为表4，即PDSCH的MCS索引表2，MCS索引为5，则网络设备根据MCS索引确定时隙数集合B为{3}，则所述时隙数K＝3，同时RV指示信息rv id＝1或3，且不配置repK-RV，即默认为{0,2,3,1}。应理解，“约束RV指示信息rv id和RV序列指示信息repK-RV，使得RV0和RV1必须分别映射到至少一个传输时机的时频资源上”在该示例中可以理解为，如果能够映射的时域资源中只有三个传输时机，那么rv id＝1时，RV1、RV0、RV2可以分别映射到一个传输时机上，rv id＝3时，RV3、RV1、RV0可 以分别映射到一个传输时机上。
应理解，可能的实现方式二中的传输时机数集合B中包括的K满足第二条件：
Figure PCTCN2022091408-appb-000132
其中，R为编码码率。在对信息比特进行LDPC编码时采用如表2所示的LDPC BG1时，母码码率为1/3，即信息比特约占编码比特的1/3，RV0至RV1之间的信息比特约占编码后信息比特串的
Figure PCTCN2022091408-appb-000133
那么在循环缓存中，RV0与RV1之间均为信息比特，RV1中也包括一部分信息比特。信息比特数为N info＝N RE·Q·R·ν·K，循环缓存中的编码比特数为3×N info，则RV0与RV1之间的信息比特数为
Figure PCTCN2022091408-appb-000134
一个传输时机的时频资源可以承载的比特数为N TO＝N RE·Q·ν，则当满足第二条件时，N info≥N TO，且，
Figure PCTCN2022091408-appb-000135
那么即可使得RV0至RV1之间的信息比特被一个传输时机上的时频资源完全承载。
图12示出了本申请实施例信息发送的方法的可能的实现方式二的示意图。如图12所示，圆环表示循环缓存，存储信息比特经过信道编码之后得到的编码后比特串序列，圆环中的空白部分为编码后的校验比特，圆环中的阴影部分为编码后的信息比特。
S502至S504与可能的实现方式一类似，在此不多赘述。
需要说明的是，可能的实现方式二中，当网络设备执行S501时，本申请对于终端设备执行的资源映射的方法不做限定，终端设备执行的S503可以替换为现有的各种资源映射的方法；当终端设备执行S503时，本申请对应网络设备执行的确定传输时机数的方法不做限定，网络设备执行的S501可以替换为现有的各种确定传输时机数的方法。
本申请实施例，编码码率与传输时机数的乘积大于1且小于或等于22/17，并且约束RV0和RV1分别映射到不同的传输时机时，可以使得编码后比特序列中的信息比特能够被多个传输时机完全承载。网络设备通过编码码率确定出满足条件的传输时机数的集合，从该集合中确定传输时机数，发送给终端设备，终端设备根据该传输时机数进行资源映射时，能够使得信息比特完整地映射到时频资源上进行传输，提高解调性能。
下面以每个时隙分配的时域资源一致为例，结合图13，介绍可能的实现方式三。
S501包括可能的实现方式一中S501中的确定传输时隙数集合A的所有相关内容，并在此基础上，并根据选择比特的长度对应的时频资源包括的传输时机的个数M，将传输时机数集合A的上限扩大M倍，构成传输时机数集合A-M，在传输时机数集合A-M范围内确定时隙数K。应理解，结合本申请前述对“冗余版本”、“速率匹配”、“比特选择”的相关说明可知，选择的编码比特的长度就是被映射的时频资源的大小，例如被映射的时频资源是M个TO上的时频资源，那么选择比特的长度就是M个TO上的时频资源，速率匹配的粒度即为M个TO，也即RV更新粒度为M个传输时机。可能的实现方式三主要讨论M大于1的情况。
另外，S501中的网络设备向终端设备发送的资源映射参数中除了时隙数K外，还包括第一指示信息，该第一指示信息用于指示被映射的时频资源的大小为M个传输时机，或者，该第一指示信息用于指示选择比特的长度为M个传输时机上的资源，或者，第一指示信息用于指示RV更新粒度为M个传输时机。
需要说明的是，该可能的实现方式三在进行资源映射时是以M个传输时机为粒度进 行速率匹配，换句话说。
示例性的，MCS表为PDSCH的MCS索引表1，即表3，MCS索引为3，M＝2，时隙数集合A为{1,2,3,4}，则时隙数集合A-M为{1,2,..,8}，所述时隙数K的取值应当是{1,2,..,8}中的一种。
应理解，可能的实现方式三中的传输时机数集合A-M中包括的K满足第三条件：R·K≤M，其中，R为编码码率。由于信息比特数为N info＝N RE·Q·R·ν·K，M个传输时机的时频资源可以承载的比特数为N TO＝N RE·Q·ν·M，则当满足第三条件时，N info≤N TO，那么信息比特能够被M个传输时机的时频资源完全承载。
在可能的实现方式三中，图13示出了本申请实施例信息发送的方法的可能的实现方式三的示意图。其中，图13中的(a)以LDPC BG1、M＝2为例示出了满足第三条件时的资源映射的示意图。如图13中的(a)所示，圆环表示循环缓存，存储信息比特经过信道编码之后得到的编码后比特串序列，圆环中的空白部分为编码后的校验比特，圆环中的阴影部分为编码后的信息比特。BG1母码码率为1/3，即信息比特约占编码比特的1/3。以RV0为起点的编码后比特串序列可以被PUSCH#0和PUSCH#1完全承载，以RV1为起点的编码后比特串可以被PUSCH#6和PUSCH#7承载，以RV2为起点的编码后比特串可以被PUSCH#2和PUSCH#3承载，以RV3为起点的编码后比特串可以被PUSCH#4和PUSCH#5承载。
S502，网络设备向终端设备发送资源映射参数，相应地，终端设备接收来自网络设备的资源映射参数，该资源映射参数中包括时隙数K和第一指示信息。
可选地，网络设备可以通过高层信令或者DCI发送资源映射参数。
S503，终端设备根据资源映射参数将编码比特映射到上行传输的时频资源。
当终端设备接收到的资源映射参数中包括上述第一指示信息，终端设备根据已知的编码码率R和网络设备发送的时隙数K的乘积小于第二切换门限时，即R·K≤M·μ时，终端设备使用第四资源映射机制进行资源映射。当R·K≥M·μ时，终端设备使用第二资源映射机制进行资源映射。示例性地，当LDPC编码使用BG1时，μ可以是集合
Figure PCTCN2022091408-appb-000136
Figure PCTCN2022091408-appb-000137
中的一个。
示例性地，假设第一指示信息指示M＝2，RV指示信息rv id＝0，RV序列为{0,2,3,1}，时隙数K＝8，图13中的(b)示出了终端设备使用第四资源映射机制时的示意图。如图13中的(b)所示，第四资源映射机制，以RV指示信息rvid为RV循环起点，RV序列指示信息repK-RV为RV循环顺序，RV更新粒度为2次传输时机，从循环缓存中对应位置将编码比特取出并映射至对应的传输时机上的时频资源。应理解，第四资源映射机制与第一资源映射机制的不同点在于，第四资源映射机制的RV更新粒度为M次传输时机，即每M个传输时机更新一次RV。换句话说，第四资源映射机制与第一资源映射机制的不同点在于，第四资源映射机制的速率匹配粒度为M次传输时机，比特交织的粒度也为M次传输时机。
终端设备使用第二资源映射机制的情况参考可能的实现方式一中的说明。
S504与可能的实现方式一中类似，在此不多赘述。
需要说明的是，可能的实现方式三中，当网络设备执行S501时，本申请对于终端设 备执行的资源映射的方法不做限定，终端设备执行的S503可以替换为现有的各种资源映射的方法；当终端设备执行S503时，本申请对应网络设备执行的确定传输时机数的方法不做限定，网络设备执行的S501可以替换为现有的各种确定传输时机数的方法。
本申请实施例，编码码率与传输时机数的乘积小于或等于N(N为大于1的正整数)，时，可以使得编码后比特序列中的信息比特能够被N个传输时机完全承载。网络设备通过编码码率确定出满足编码码率与传输时机数的乘积小于或等于1这一条件的传输时机数的集合，将该集合的上限扩大M倍，从该集合中确定传输时机数，网络设备将传输时机数发送给终端设备的同时向终端设备发送指示N的指示信息，终端设备根据该传输时机数进行资源映射时，能够使得信息比特完整地映射到时频资源上进行传输，提高解调性能。
下面以每个时隙分配的时域资源一致为例，结合图14，介绍可能的实现方式四。
S501，网络设备确定上行传输的资源映射参数。
网络设备根据编码码率R，时隙数K，和第四条件确定资源映射参数，第四条件为R·K≤N≤K，资源映射参数包括时隙数K和第二指示信息，第二指示信息用于指示RV0的更新粒度为N，即RV0每N个传输时机更新一次。
应理解，时隙数K是网络设备预先确定的，例如可以是根据覆盖性能、业务类型、服务质量(quality of service，QoS)等因素综合确定时隙数K。
应理解，第二指示信息仅指示RV0的更新粒度为N，因此在该可能的实现方式四中，RV2、RV3、RV1的更新粒度仍为一个传输时机。
应理解，为了解决一个传输时机的时频资源无法承载完整的信息比特的问题，该可能的实现方式四通过约束信息比特可以被N个传输时机的时频资源完全承载，即N info≤N TO，来解决该问题。信息比特数为N info＝N RE·Q·R·ν·K，N个传输时机的时频资源可以承载的比特数为N TO＝N RE·Q·ν·N，要满足N info≤N TO，可得R·K≤N，又因为承载RV0的传输时机的数量N一定小于承载编码比特的传输时机的数量K，因此第四条件为R·K≤N≤K。
示例性的，假设R＝379/1024，K＝4，满足第四条件时，
Figure PCTCN2022091408-appb-000138
则N＝2,3,4。
可选地，当rv id＝0时，可以使得RV0尽可能地映射至上行传输的时频资源，因此该可能的实现方式四中，优选在资源映射参数中向终端设备指示rvid＝0。
图14示出了本申请实施例信息发送的方法的可能的实现方式四的示意图。其中，图14中的(a)以LDPC BG1、N＝2为例示出了满足第四条件时的资源映射的示意图。如图14中的(a)所示，圆环表示循环缓存，存储信息比特经过信道编码之后得到的编码后比特串序列，圆环中的空白部分为编码后的校验比特，圆环中的阴影部分为编码后的信息比特。BG1母码码率为1/3，即信息比特约占编码比特的1/3。以RV0为起点的编码后比特串序列可以被PUSCH#0和PUSCH#1完全承载，以RV1、RV2、RV3为起点的编码后比特串序列分别可以被PUSCH#4、PUSCH#2、PUSCH#3承载。
S502，网络设备向终端设备发送资源映射参数，相应地，终端设备接收来自网络设备的资源映射参数，该资源映射参数中包括时隙数K和第二指示信息。
可选地，网络设备可以通过高层信令或者DCI发送资源映射参数。
S503，终端设备根据资源映射参数将编码比特映射到上行传输的时频资源。
当终端设备接收到的资源映射参数中包括上述第二指示信息，终端设备根据该第二指 示信息确定使用第三资源映射机制。
示例性地，假设第二指示信息指示N＝2，RV指示信息rv id＝0，RV序列为{0,2,3,1}，时隙数K＝8，图14中的(b)示出了终端设备使用第四资源映射机制时的示意图。第三资源映射机制，以RV指示信息rv id为RV循环起点，RV序列指示信息repK-RV为RV循环顺序，从循环缓存中对应位置将编码比特取出并映射至对应的传输时机上的时频资源。其中，RV0更新粒度为2次传输时机，RV1、RV2、RV3更新粒度为1次传输时机，换句话说，RV0更新至RV2需要两个传输时机，其它RV更新仅需要一个传输时机。应理解，第三资源映射机制与第一资源映射机制的唯一不同点在于RV0更新粒度为N次传输时机，即每N个传输时机更新一次RV0。
S504与可能的实现方式一中类似，在此不多赘述。
本申请实施例，在信息比特无法被一个传输时机的时频资源完整承载时，网络设备向终端设备发送指示信息，用于指示终端设备用于承载信息比特的传输时机的数量，终端设备根据网络设备指示的传输时机的数量进行资源映射，能够使得信息比特能够完整地映射到时频资源上进行传输，提高解调性能。
下面以每个时隙分配的时域资源一致为例，结合图13，介绍可能的实现方式五。
网络设备根据编码码率R，时隙数K，和第五条件确定资源映射参数，第五条件为R·K≤M≤K，资源映射参数包括时隙数K和第一指示信息，第一指示信息用于指示RV的更新粒度为N，即每N个传输时机更新一次RV。
应理解，时隙数K是网络设备预先确定的，例如可以是根据覆盖性能、业务类型、服务质量(quality of service，QoS)等因素综合确定时隙数K。
应理解，为了解决一个传输时机的时频资源无法承载完整的信息比特的问题，该可能的实现方式四通过约束信息比特可以被M个传输时机的时频资源完全承载，即N info≤N TO，来解决该问题。第五条件与第四条件的推导过程类似，在此不多赘述。
可选地，当rvid＝0时，可以使得RV0尽可能地映射至上行传输的时频资源，因此该可能的实现方式四中，优选在资源映射参数中向终端设备指示rvid＝0。
在可能的实现方式五中，图13示出了本申请实施例信息发送的方法的可能的实现方式五的示意图。其中，图13中的(a)以LDPC BG1、M＝2为例示出了满足第五条件时的资源映射的示意图。如图13中的(a)所示，圆环表示循环缓存，存储信息比特经过信道编码之后得到的编码后比特串序列，圆环中的空白部分为编码后的校验比特，圆环中的阴影部分为编码后的信息比特。BG1母码码率为1/3，即信息比特约占编码比特的1/3。以RV0为起点的编码后比特串序列可以被PUSCH#0和PUSCH#1完全承载，以RV1为起点的编码后比特串可以被PUSCH#6和PUSCH#7承载，以RV2为起点的编码后比特串可以被PUSCH#2和PUSCH#3承载，以RV3为起点的编码后比特串可以被PUSCH#4和PUSCH#5承载。

可选地，网络设备可以通过高层信令或者DCI发送资源映射参数。

则传输时机数集合A-P为{1，2，3，4，6}，则传输时机K的取值应当是{1，2，3，4，5，6}中的一种。应理解，传输时机数集合A-P的上限6是根据对

应理解，可能的实现方式八中的传输时机数集合A-P中包括的K满足第六条件：R·K≤P。假设一个TBoMS传输包括的TO个数是偶数K的情况下，对于LDPC编码使用表2所示的BG1和BG2时，“SU”时隙包括的信息比特数为

图16中的(b)示出了终端设备使用第一资源映射机制时的示意图。第一资源映射机制，即RV循环机制，以所述RV指示信息rv id为RV循环起点，所述RV序列指示信息repK-RV为RV循环顺序，RV更新粒度为一次传输时机，从循环缓存中对应位置将编码比特取出并映射至对应的传输时机上的时频资源。例如，如图16中的(b)所示，以rvid＝1为起点，将RV0、RV1、RV2、RV3分别映射到一个传输时机上，且RV0映射到长传输时机上。
图16中的(c)示出了终端设备使用第二资源映射机制时的示意图。第二资源映射机制，即连续资源映射机制，从循环缓存中的第一个编码比特开始将编码比特取出，映射到K个传输时机的时频资源上，RV不进行更新。例如，如图16中的(c)所示，以rvid＝0为起点，将RV0映射到一个TBoMS的传输时机上。
需要说明的是，该第二资源映射机制以所有传输时机为粒度进行速率匹配，换句话说，该第二资源映射机制是以整个TBoMS为粒度进行速率匹配。同样，第二资源映射机制比特交织的粒度也是所有传输时机或整个TBoMS。
S504，终端设备在上行传输的时频资源上向网络设备发送上行信号；相应地，网络设备在上行传输的时频资源上接收来自终端设备的上行信号。
需要说明的是，可能的实现方式八中，当网络设备执行S501时，本申请对于终端设备执行的资源映射的方法不做限定，终端设备执行的S503可以替换为现有的各种资源映射的方法；当终端设备执行S503时，本申请对应网络设备执行的确定传输时机数的方法不做限定，网络设备执行的S501可以替换为现有的各种确定传输时机数的方法。
本申请实施例，编码码率与传输时机数的乘积小于或等于P(P≥1)时，可以使得编码后比特序列中的信息比特能够被一个传输时机完全承载。网络设备通过编码码率确定出满足条件的传输时机数的集合，从该集合中确定传输时机数，发送给终端设备，终端设备根据该传输时机数进行资源映射时，能够使得信息比特完整地映射到时频资源上进行传输，提高解调性能。
下面以每个时隙分配的时域资源可以不一致、非对称帧结构为例，结合图16，介绍可能的实现方式九。
S501，网络设备确定上行传输的资源映射参数。
网络设备根据BG、调制和编码方案(modulation and coding scheme，MCS)表和MCS索引确定所述资源映射参数，所述资源映射参数包括时隙数K，RV指示信息rvid和RV序列指示信息repK-RV。
在对信息比特进行LDPC编码时采用如表2所示的LDPC BG1时，可以根据MCS索引指示，从MCS表(本申请中的表3至表7)中选择对应的传输时机数集合B，进一步地，需要将传输时机数集合B中传输时机数的上限扩大P倍，得到传输时机数集合B-P，随后在该传输时机数集合B-P中确定出时隙数K，同时，约束RV指示信息rvid和RV序列指示信息repK-RV，使得RV0映射到长传输时机的时频资源上。
应理解，可能的实现方式二中的传输时机数集合B中包括的K满足第二条件：

其中，R为编码码率。
S502至S504与可能的实现方式八中类似，在此不多赘述。
需要说明的是，可能的实现方式九中，当网络设备执行S501时，本申请对于终端设备执行的资源映射的方法不做限定，终端设备执行的S503可以替换为现有的各种资源映射的方法；当终端设备执行S503时，本申请对应网络设备执行的确定传输时机数的方法不做限定，网络设备执行的S501可以替换为现有的各种确定传输时机数的方法。
本申请实施例，编码码率与传输时机数的乘积大于P且小于或等于22/17倍的P(P≥1)，并且约束RV0和RV1分别映射到不同的传输时机时，可以使得编码后比特序列中的信息比特能够被多个传输时机完全承载。网络设备通过编码码率确定出满足条件的传输时机数的集合，从该集合中确定传输时机数，发送给终端设备，终端设备根据该传输时机数进行资源映射时，能够使得信息比特完整地映射到时频资源上进行传输，提高解调性能。
下面结合图17，对本申请的信息发送的方法600进行详细说明。方法600的具体实现有多种方式，下面对3种可能的方式进行详细说明。
终端设备在进行连续资源映射时，每个TO从循环缓存器读取编码比特的起始位置以Z c的整数倍为粒度，其中Z c表示LDPC的扩展因子(LDPC lifting size)，即LDPC编码是按照Zc的整数倍为粒度输出编码比特。
方式一，如图17中的(a)所示，y k表示映射至第k个传输时机的第一个比特在循环缓存中的位置，x k表示映射至第k个传输时机的最后一个比特在循环缓存中的位置，x k＝0,1,2，……N cb-1，其中N cb表示循环缓存中编码比特的数量，

Figure PCTCN2022091408-appb-000169
作为一个示例，Z c＝10，k＝0时，第一次进行LDPC编码后得到的编码比特包括50个比特，而映射至TO#0的编码比特只有45个，即x k＝44。那么按照方式一，映射至TO#1的比特序列的第一比特位置为y k+1＝40；按照方式二，y k+1＝50；按照方式三，y k+1＝40。
作为一个示例，Z c＝10，k＝0时，第一次进行LDPC编码后得到的编码比特包括50个比特，而映射至TO#0的编码比特只有48个，即x k＝48。那么按照方式一，y k+1＝40；按照方式二，y k+1＝50；按照方式三，y k+1＝50。
本申请实施例，终端侧在进行资源映射时，减少了查找映射至上一个传输时机或时隙的最后一个比特在循环缓存中的位置的步骤，简化了映射过程中的计算，节省了开销。
应理解的是，本申请的信息发送的方法600可以单独实施，也可以与本申请信息发送的方法的其他实施例结合实施。
下面结合图18，对本申请的信息发送的方法700进行详细说明。
如图18中的(a)所示，S701，网络设备向终端设备发送TBoMS重复传输次数，相应地，终端设备接收来自网络设备的TBoMS重复传输次数。
S702，终端设备根据TBoMS重复传输次数进行资源映射，资源映射方法与上述一致。
需要说明的是，假设传输一个TBoMS需要K个传输时机，TBoMS重复传输次数为S，S可以等于1，2，3，4……S不一定需要等于K。
示例性的，如图18中的(b)所示，传输一个TBoMS需要4个传输时机，TBoMS重复传输次数为2，可以理解为只对RV0和RV2进行重复传输。
本申请实施例，在进行重复的资源映射时，对TBoMS进行部分重复传输，在提高传输可靠性和准确性的基础上，能够缩短TBoMS重复传输的时延。
