为了便于理解本申请，下面介绍本申请实施例涉及的相关技术知识。
1.时域结构
新无线(new radio，NR)标准中，传输的帧长持续时间为10ms，每个帧(frame)被分割为10个子帧，每个子帧长1ms。每个子帧被划分为若干个时隙(slot)：当循环前缀(cyclic prefix，CP)为普通(normal)CP时，每个时隙由14个正交频分复用(orthogonal frequency-division multiplexing，OFDM)符号构成；当循环前缀为扩展(extended)CP时，每个时隙由12个OFDM符号构成。每个时隙具体的时间长度由参数集确定，其中，参数集例如可以包括子载波间隔(subcarrier spacing，SCS)。如，SCS为15kHz时，一个slot长1ms；子载波间隔为30kHz时，一个slot长0.5ms。
NR支持一个时隙用于上行传输，记为U slot；NR支持一个时隙用于下行传输，记为D slot；NR支持一个时隙既有上行也有下行的配置，记为S slot。典型的时分复用(time division duplex，TDD)系统时隙配置格式，包括DDDSU、DDDSUDDSUU、DDDDDDDDUU等。可以理解的，一个时隙中可以包括下行符号(downlink symbols)、上行符号(uplink symbols)、和灵活符号(flexible symbols)，下行符号不能用于上行传输；上行符号不能用于下行传输；而灵活符号既可用于下行传输也可用于上行传输。
在长期演进(long term evolution，LTE)标准中，上行时隙由离散傅里叶变换扩展正交频分复用(discrete Fourier transform-spread-orthogonal frequency-division  multiplexing，DFT-S-OFDM)符号构成。
2.频域结构
NR定义一个资源单元(resource element，RE)为一个OFDM符号上的一个子载波，RE是NR标准里最小的物理单元。频域上连续的12个子载波称为一个资源块(resource block，RB)。虽然一个RB固定包括12个子载波，但由于不同的子载波间隔，不同RB在频域上占用的实际带宽不一定相同。
3.上行信道和信号
NR中上行信道包括：物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)、以及物理随机接入信道(physical random access channel，PRACH)。
NR中上行信号包括：探测参考信号(sounding reference signal，SRS)，解调参考信号(demodulation reference signal，DMRS)，以及相位跟踪参考信号(phase-tracking reference signal，PTRS)。其中，上行DMRS伴随PUCCH和PUSCH传输，其时频资源占用了PUCCH或PUSCH的一部分。上行PTRS伴随PUSCH传输，其时频资源占用了PUSCH的一部分。
4.三种PUSCH传输
NR中的PUSCH传输分为三种：基于动态调度的PUSCH传输、配置许可(configured grant，CG)类型1(type1)的PUSCH传输，和CG type2的PUSCH传输。
其中，基于动态调度的PUSCH传输，即每次PUSCH传输，都用物理层指示下行控制信息(downlink control information，DCI)进行调度。在此种传输中，终端设备接收到一次上行调度，就进行一次PUSCH传输。
其中，CG Type1的PUSCH传输，即半静态调度的PUSCH传输，接收高层配置(包含rrc-ConfiguredUplinkGrant的高层参数configuredGrantConfig)，不接收物理层指示DCI，协议中称为configured uplink grant。在此种传输中，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，就可以利用这些资源发送PUSCH；如果没有上行数据需要发送，则不进行数据发送。
其中，CG Type2的PUSCH传输，即先接收高层配置(不包含rrc-ConfiguredUplinkGrant的高层参数configuredGrantConfig)，再由物理层指示DCI激活或者去激活，协议中称为configured uplink grant based on L1signalling。此种传输中，高层配置了一些半持续资源，然后由物理层信令激活/去激活：激活时行为和配置许可Type1PUSCH传输类似；没有激活时，这些资源不能使用。
5.PUSCH处理的一般步骤
在NR中，PUSCH的数据(uplink shared channel，UL-SCH)传输中，一个PUSCH传输块(transport block，TB)的编码过程，可以参见图1。图1为一种编码过程的示意图，结合图1，可以看出，针对一个TB，终端设备可以依次进行传输块循环冗余校验(cyclic redundancy check，CRC)附着、码块(code block，CB)分割、码块CRC附着、信道编码、速率匹配、码块级联、加扰(scrambling)、调制(modulation)、预编码、符号映射等。
若TB的比特序列为a 0,a 1,a 2,a 3,...,a A-1，A为有效载荷大小。终端设备对该TB进行传输块CRC附着，可以包括：终端设备根据TB的有效载荷大小A，确定CRC的生成多项式以及校验比特数L；终端设备根据TB的比特序列和CRC的生成多项式生成校验比特序列p 0,p 1,p 2,p 3,...,p L-1，并将校验比特序列p 0,p 1,p 2,p 3,...,p L-1附着到TB的比特序列，得到CRC附着后的比特序列b 0,b 1,b 2,b 3,...,b B-1。其中，B＝A+L。接着，若B大于最大码块尺寸K cb，终端设备对TB的比特序列进行码块分割，得到C个码块，C个码块中每个码块的比特流为 c r0,c r1,c r2,c r3,...,c r(K′-L-1)，r为大于或等于0，且小于C的整数，r为码块号，K′为K r或K，K r＝K为第r个码块的比特数。然后，终端设备根据每个码块的比特流确定每个码块的CRC校验比特序列
Figure PCTCN2022101295-appb-000041
并将每个码块的CRC校验比特序列
Figure PCTCN2022101295-appb-000042
附着到对应码块，得到每个码块附着后的比特序列
Figure PCTCN2022101295-appb-000043
其中，每个码块的校验比特数L＝24。紧接着，在NR中，对于数据信道，终端设备可以采用低密度奇偶校验(low density parity check，LDPC)码，对每个码块进行LDPC信道编码，其中，信道编码的输入例如可以为c 0,c 1,c 2,c 3,...,c K-1，信道编码的输出例如可以为d 0,d 1,d 2,d 3,...,d N-1，N为信道编码的输入经过信道编码后序列的长度。当然，终端设备还可以对每个码块进行速率匹配，速率匹配可以包括比特选择(bit selection)和比特交织(bit interleaving)，具体不在此赘述。其中，速率匹配的输入例如可以为d 0,d 1,d 2,d 3,...,d N-1，速率匹配的输出例如可以为f 0,f 1,f 2,f 3,...,f E-1，E为速率匹配的输入经过速率匹配后序列的长度。然后，终端设备还可以将速率匹配后的C个码块的比特f rk顺序级联，得到比特序列g t。其中，k为大于或等于0，且小于或等于E r-1的整数，E r为第r个码块经过速率匹配后的比特数，t为大于或等于0，且小于或等于G-1的整数，G为比特序列g t的长度。
另外，终端设备还可以对比特序列g t进行加扰。如对于单码字q＝0，加扰前的比特序列为
Figure PCTCN2022101295-appb-000044
加扰后的比特序列为
Figure PCTCN2022101295-appb-000045
为一个星座点对应的比特数。可以理解的，加扰类似于
Figure PCTCN2022101295-appb-000046
为加扰后的比特序列，b (q)(i)为加扰前的比特序列，c (q)(i)为加扰序列，i为大于或等于0，且小于或等于
Figure PCTCN2022101295-appb-000047
的整数。接着，终端设备还可以对加扰后的比特序列进行星座调制，得到复数调制符号序列
Figure PCTCN2022101295-appb-000048
然后，终端设备可以将复数调制符号序列和预编码矩阵进行相乘，得到预编码后的复数调制符号序列
Figure PCTCN2022101295-appb-000049
ap(antenna port)为天线端口数。最后，针对每个天线端口，终端设备可以将预编码后的复数调制符号序列映射到时频资源上。映射时可以跳过协议预设的预留资源(比如DMRS、PTRS等)，映射可以按照先频域后时域的顺序进行，如从第一个OFDM符号的最低序号子载波开始，按子载波序号升序映射，映射完第一个OFDM符号的所有子载波之后，再从第二个OFDM符号的最低序号子载波开始映射。以此类推，直到映射完所分配的时频资源。
6.PUSCH的两种重复类型(repetition Type)
NR中PUSCH重复类型分为两种：PUSCH repetition Type A和PUSCH repetition Type B，前者是Rel-15版本中采用的，后者是Rel-16版本中新引入的。
其中，PUSCH repetition Type A以时隙为单位重复K次，起始符号S是相对时隙的开始位置；L是分配给PUSCH的，从S开始的连续符号个数；S与L由开始与长度指示SLIV来决定。在K>1时，在K个连续时隙上应用相同的符号分配。协议中规定有效的S与L组合的设计，使得PUSCH重复类型A不会跨越时隙边界。如果分配的某一组符号中，有符号不能用于发送该PUSCH重复，则取消此次PUSCH重复的发送。
示例性的，参见图2，图2为PUSCH repetition Type A的映射图案示意图。可以理解的，在图2中，S＝0，L＝10，K＝4。在每个时隙中，从起始符号S(S＝0)开始连续L(L＝10)个符号用于发送PUSCH。如，在时隙1，从左往右第0个符号开始连续10个符号用于发送PUSCH，即Rep#1；在时隙2，从左往右第0个符号开始连续10个符号用于发送PUSCH，即Rep#2；在时隙3，从左往右第0个符号开始连续10个符号用于发送PUSCH，即Rep#3；在时隙4，从左往右第0个符号开始连续10个符号用于发送PUSCH，即Rep#4。因此，可以看出，PUSCH以时隙为单元重复4次，即Rep#1至Rep#4。
其中，PUSCH repetition Type B以网络侧指示的长度L为单位重复K次，起始符号S 是相对时隙的开始位置；L是分配给PUSCH的，从S开始的连续符号个数。PUSCH重复类型B相比较PUSCH重复类型A更为灵活，可能会出现一个repetition跨越时隙边界，或一个repetition中包含无效符号(invalid symbol(s))的情况，此时，该repetition会出现分裂。协议中将分裂前的repetition称为名义重复(nominal repetition)，将分裂后的repetition称为实际重复(actual repetition)，网络侧指示的重复次数K指的是nominal repetition的总次数。
示例性的，参见图3，图3为一种PUSCH repetition Type B的映射图案示意图。可以理解的，在图3中，S＝11，L＝7，K＝4。由图3可见，4次nominal repetition，由于时隙边界的存在，分裂成6次actual repetition。
当PUSCH重复类型B的repetition遇到无效符号，比如下行符号时，nominal repetition会首先将这些无效符号去掉。如果一个nominal repetition中的潜在有效符号数大于0，那么该nominal repetition会包括一个或多个actual repetition，每个actual repetition利用连续的有效符号传输(除非L＝1，否则单符号的actual repetition被忽略)。
示例性的，参见图4，图4为又一种PUSCH repetition Type B的映射图案示意图。可以理解的，在图4中，S＝0，L＝7，K＝2。在图4中，2次nominal repetition，由于无效符号(即下行符号)的存在，分裂成3次actual repetition，且用于PUSCH传输的有效符号数目也降低。
7.PUSCH传输数据速率的限制
在一个小区组中，第j个服务小区，j＝0,1,2,…,J-1，如果时隙s j上的任一时刻，以下条件不满足，则终端设备不需要在第j个服务小区中时隙s j中处理PUSCH的传输：
Figure PCTCN2022101295-appb-000050
其中，J为属于一个频率范围(frequency range，FR)的配置服务小区个数；对第j个服务小区，M为时隙s j中传输的TB数目。对PUSCH repetition Type B，每个actual repetition被分别计算。
其中，
Figure PCTCN2022101295-appb-000051
为一个时隙的持续时间，μ(j)为在第j个服务小区中时隙s j中的PUSCH的子载波间隔配置。NR中子载波间隔配置μ与子载波间隔Δf的关系如下表所示：
μ Δf＝2 μ×15[kHz] 循环前缀(cyclic prefix，CP)
0 15 Normal
1 30 Normal
2 60 Normal,Extended
3 120 Normal
4 240 Normal
其中，对于第m个TB，有
Figure PCTCN2022101295-appb-000052
A为该传输块的比特数，如上述5中的有效载荷大小。C为该传输块的总码块数，如上述5中的总码块数。C′为该传输块的调度的码块数。具体来说，如果在调度该TB的DCI中，没有码块组传输信息(code block group transmission information，CBGTI)域的话，则C′＝C；如果调度该TB的DCI中，有CBGTI域的话，则C′为传输块的调度的码块数。
DataRate为对所有载波求和后的最大数据速率，单位为兆比特每秒(megabits per second，Mbps)。其计算公式为对多个分量载波(component carrier，CC)求和的形式，参数都是由高层给定的，终端设备最大能支持的参数，由此计算出终端设备支持的最大数据速率。
示例性的，参见图5，图5为在不同载波上传输的TB的数据速率示意图。如图5所示，共有3个服务小区，3个CC对应的子载波间隔分别为60kHz、30kHz、15kHz，TB0、TB1、TB2分别在CC0、CC1、CC2上传输。在时刻1，不同载波上传输的TB的数据速率满足以下公式：
Figure PCTCN2022101295-appb-000053
其中，TB0、TB1和TB2分别表示各个TB所传输的比特数。
除了上述在一整个小区组中对终端设备数据速率的限制，针对第j个服务小区，也有对终端设备数据速率的限制。具体包括以下任意一种条件：
条件1.如果对该服务小区，高层参数PUSCH-ServingCellConfig中的processingType2Enabled被配置了，且被配置为enable；(也就是终端设备支持处理能力2)；或，
条件2.当终端设备使用编码调制方式(modulation and coding scheme，MCS)表5.1.3.1-1或5.1.3.1-3时，W＝28；当终端设备使用MCS表5.1.3.1-2,6.1.4.1-1，或6.1.4.1-2时，W＝27：如果对一个PUSCH，至少有一个I MCS>W。换句话来说，该PUSCH为混合自动重传(hybrid automatic repeat request，HARQ)；或，
条件3.如果对PUSCH repetition Type B是一次实际重复；
可以理解的，在上述任意一个条件的限制下，在以下条件不满足时，终端设备不需要处理PUSCH的传输：
Figure PCTCN2022101295-appb-000054
其中，L为分配给PUSCH的符号数；M为PUSCH中的TB数；
Figure PCTCN2022101295-appb-000055
为一个时隙内的符号数，μ为PUSCH的子载波间隔配置；V j,m可以参考上述相关描述，在此不加赘述。DataRateCC为一个载波的最大数据速率，单位为Mbps。
8.多时隙PUSCH的传输块处理
在NR R-15/R-16协议版本中，在绝大多数情况下，一个传输块只在一个时隙上传输(除非对PUSCH repetition Type B，在名义重复被时隙边界分割为实际重复时，相同传输块在至多两个时隙上传输)。也就是说，目前NR协议中，基站不会主动调度一个传输块在多个slot上传输。
在R-17覆盖增强(coverage enhancement，CE)的讨论中，多时隙PUSCH传输块处理(transport block processing over multi-slot PUSCH，TBoMS)工作项描述(work item description，WID)被审批通过，TBoMS指基站侧调度一个TB对应在多个slot上发送PUSCH。
TBoMS的优势可总结如下：在上行覆盖受限的场景下，通过在多个时隙聚合较小的包(packet)，TBoMS可以提升信道编码增益；通过在多个时隙上传输单个TB，只有一个TB循环冗余校验码附着，降低了TB CRC所占的比特数；TBoMS的单个TB在时域上拉长，降低了频域所占RB数，从而提升功率谱密度。
9.TBoMS的时域资源分配
在最近的RAN1#105-e会议讨论中，将TBoMS的时域资源分配(time domain resource allocation，TDRA)方式确定为PUSCH repetition Type A的TDRA方式，将该结论写入协议。此外，对于非成对频谱(也就是TDD)场景下，在S时隙分配传输TBoMS所用的资源，S时隙的TDRA是否有必要优化，仍待讨论。
10.TBoMS的传输块大小
在RAN1#105-e会议讨论中，确定TBoMS的传输块大小(transport block size，TBS)的计算方式为：首先基于TBoMS传输分配的前L个符号确定RE数目，之后再乘以K≥1。此处，L为PUSCH的TDRA的SLIV中的L，代表符号数目；K的定义仍待讨论。
此外，在RAN1#104-e会议讨论中，将TBoMS的最大TBS不变写入协议。也就是说，虽然TBoMS的单个TB被拓展到多个slot上发送，但TBoMS的单个TB的最大尺寸，仍与R-15/R-16中在一个时隙上发送的TB的最大尺寸一致。
11.TBoMS的传输时机
在NR R-15/R-16协议版本中，PUSCH的传输时机(transmission occasion，TO)，对非重复的PUSCH，以及PUSCH repetition Type A给出了规定，TO为一个时隙中PUSCH的一次重复。TO是功率控制(power control)、冗余版本(redundancy version，RV)循环(cycling)的基本单元。
在RAN1#104-bis-e的会议讨论中，提出为TBoMS定义传输时机的工作假设(working assumption)，即为TOT(transmission occasion for TBoMS)。在RAN1#105-e会议讨论中，将TOT确定为由至少一个或多个连续的用于上行传输的物理时隙构成。同时，TOT与信号生成相关的设计层面，比如速率匹配(rate matching，RM)、RV cycling、功率控制、冲突处理(collision handling)等的关系，仍待讨论。
12.TBoMS的速率匹配与RV
在RAN1#105-e会议讨论中，确定了以下三种速率匹配的方式，考虑在下一次会议，也就是RAN1#106-e会议中筛选，最终只选出一种RM的方式：
(1)速率匹配逐时隙执行；
(2)速率匹配逐TOT执行，亦即RM在一个TOT分配的所有时隙上连续地执行；
(3)速率匹配在TBoMS分配的所有时隙/所有TOT上连续地执行。
在NR协议流程中，冗余版本的确定属于比特选择的部分。对于TBoMS的RV cycling，在整个TBoMS上，可能用单个RV，也可能用多个RV，仍待后续会议讨论。
目前，在计算物理上行共享信道对应的数据速率时，针对的是一个传输块不跨越时隙传输的场景。然而，如果针对一个TB跨越多个时隙传输的场景(即对于R-17将要引入的TBoMS)，依旧按照一个TB不跨越时隙传输的场景来计算数据速率的话，往往会存在计算出来的数据速率误差较大的问题。换句话来说，如果一个TB跨越多个时隙传输时，依旧采用上述7中涉及到的数据速率计算公式(分子仍为该TB被调度传输的比特数，而分母为一个时隙的持续时间(多CC公式)或一个时隙中L个符号的持续时间(单CC公式))，从而导致计算出来的数据速率远大于TBoMS实际传输的数据速率，这也限制TBoMS传输的TBS或限制TBoMS的调度。另外，上述7中涉及到的数据速率计算公式
Figure PCTCN2022101295-appb-000056
是对多个服务小区上的TB求和的，对TBoMS计算出的数据速率比真实值要大，也会限制其他CC上PUSCH传输的数据速率小于终端设备能够支持的最大数据速率，从而限制了其他CC上TB的调度或限制了其他TB的TBS。因此，针对一个TB跨越多个时隙传输的场景，如何精准确定数据速率成为当前阶段亟待解决的技术问题。
