在本申请实施例中，以VoIP业务场景为例，其传输时间间隔为20毫秒，但是现有协议中指示的重复技术与TBoMS技术的相关参数进行结合，最大只能占用16毫秒的传输时机(TBoMS的聚合时隙个数为1时，没有起到两种技术结合的效果)，本采用本申请实施例的对应关系确定的第一时长大于16毫秒，达成了更好的覆盖增加的效果。
结合第一方面或第二方面，在一种可能的设计中，上行传输的最大可占用时隙个数为第一时隙个数，根据对应关系确定的上行传输占用时隙为第二时隙个数，第二时隙个数小于或等于第一时隙个数。
本申请实施例中，第一信息指示的对应关系应该满足上行传输的最大可占用时隙个数的约束条件，避免产生编码错误。

结合第一方面或第二方面，在一种可能的设计中，在第二集合中包括5和/或10的情况下，T＝1。
本申请实施例中，第一时长为20毫秒，以VoIP业务场景为例，其传输时间间隔为20毫秒，即是说根据对应关系确定的上行传输的占用时长与传输时间间隔相等，上行传输完全占用传输时间间隔，能够充分利用传输实际进行覆盖增强，充分提升覆盖增强的效果。
结合第一方面或第二方面，在一种可能的设计中，在子载波间隔为15kHZ时，重复传输次数M为4与聚合时隙个数为5存在第一对应关系。

本申请实施例中，上述设定的三种第一对应关系，都能满足第一时长为20毫秒的设定，并且不需要增加重复传输次数M对应的聚合时隙个数种类(T＝1)，而只需要增加重复传输次数M的取值集合，和/或TBoMS的聚合时隙个数的取值集合，就能够使得上行传输完全占用传输时间间隔，降低了第一信息对应关系的复杂度和信令开销，同时能够充分利用传输实际进行覆盖增强，充分提升覆盖增强的效果。
结合第一方面或第二方面，在一种可能的设计中，第二信息为无线资源控制RRC信令，或为系统信息块SIB；和/或第一信息承载在下行控制信息DCI或RRC信令中。
本申请实施例中，通过RRC信令或SIB进行重复传输次数与TBoMS的聚合时隙个数的对应关系的配置，再通过DCI对重复传输次数M与聚合时隙个数的对应关系进行指示，一方面可以通过RRC信令或SIB的配置使得配置信息能够适用于整个通信过程，另一方面又能够通过每次DCI的下发更新指示信息，提升指示对应关系的灵活性。若通过RRC信令进行对应关系的指示，能够减少对DCI的更改，减少终端设备盲检的复杂度。
结合第一方面或第二方面，在一种可能的设计中，第一信息承载在RRC信令中，RRC信令中包括重复传输次数M与聚合时隙个数集合的第一对应关系，聚合时隙个数集合中的不重复元素个数为T；或者RRC信令中包括多个第一重复传输次数中每个第一重复传输次数与一种聚合时隙个数的对应关系。
本申请实施例中，通过RRC信令直接指示重复传输次数M与聚合时隙个数的对应关系，减少了大量配置信息下发过程可能造成的资源开销。
结合第一方面或第二方面，在一种可能的设计中，若对应关系包括多个第一重复传输次数与一种聚合时隙个数的对应关系，在上行传输中，每个第一重复传输次数对应的重复传输是独立编码的。
在本申请实施例中，上行传输过程中针对多个第一重复传输次数，每个第一重复传输次数的重复传输进行独立编码，可以降低接收端解码的复杂度，提升解码效率，进而提升数据传输效率。
结合第一方面或第二方面，在一种可能的设计中，当T＝M时，M次重复传输与T种聚合时隙个数为一一对应关系；和/或当1＜T＜M时，T种聚合时隙个数循环与M次重复传输对应。

随着5G新空口(new radio，NR)的发展与演进，增强移动带宽(enhanced mobile broadband，eMBB)、大规模机器类型通信(massive machine type communication，MMTC)、超可靠低延迟(ultra-reliable low-latency communications，uRLLC)等众多的应用场景需求逐渐渗透地面通信网络(terrestrial Network,TN)的各个层面。但万物互联的美好愿景仍受限制于一些特殊的通信场景，如沙漠、森林、海洋等地区，或飞机、高铁等高速移动交通工具中，因受成本或物理条件等的制约，无法采用传统的地面基站方式为其提供网络覆盖。因此，5G网络中的NTN技术应运而生。相比于传统的地面通信网络，NTN中采用典型的如卫星、HAPS等通信设备参与布网技术，以实现真正的全球范围网络覆盖，其优势与发展战略重要性不言而喻。卫星通信系统与5G相融合，取长补短，共同构成全球无缝覆盖的海、陆、空、天一体化综合通信网，满足用户无处不在的多种业务需求，是未来通信发展的重要方向。
针对NTN场景，覆盖增强技术是重要的讨论话题。在NTN场景中，RTT远远超过地面蜂窝系统，因此存在小区边缘用户链路预算较差的情况。尤其对于对地静止轨道(geostationary earth orbit，GEO)，中地球轨道(medium earth orbit，MEO)，低地球轨道(low earth orbit，LEO)-1200等轨道高度相对较高的场景，卫星在地面覆盖区域的边缘小区(或波束)，链路预算差的情况更加明显。此外，考虑到手机终端直连卫星的场景，由于手机终端发射功率较小，天线数目较少，导致NTN场景中多种物理层传输信道解码存在瓶颈，尤其对于上行传输场景，比如物理上行共享信道(physical uplink shared channel，PUSCH)、物理上行控制信道(physical uplink controlchannel，PUCCH)消息(Msg)3，以及PUCCH、物理下行控制信道(physical uplink controlchannel，PDCCH)等控制信道等，覆盖增强的需求亟待解决。
本申请实施例即是针对NTN场景下的覆盖增强技术提出解决方案。
首先结合图示对本申请实施例涉及的系统架构和专业术语进行介绍。
请参阅图1，图1为本申请实施例提供的一种通信系统架构示意图，如图1所示，NR与NTN融合的通信网络中，地面移动终端通过5G NR接入网络，5G基站部署在卫星上，并通过无线链路与地面的核心网相连。同时，在卫星之间存在无线链路，完成基站与基站之间的信令交互和用户数据传输。图1中的各个网元以及他们的接口说明如下：
终端:支持5G NR的移动设备，具体可以指用户设备(user equipment，UE)、接入终端、用户单元(subscriber unit)、用户站、移动台(mobile station)、客户终端设备(customer-premises equipment，CPE)、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。终端设备还可以是卫星电话、蜂窝电话、智能手机、无线数据卡、无线调制解调器、机器类型通信设备、可以是无绳电话、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)、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、高空飞机上搭载的通信设备、可穿戴设备、无人机、机器人、智能销售点(point of sale，POS)机、设备到设备通信(device-to-device，D2D)中的终端、车到一切(vehicle to everything， V2X)中的终端、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)中的无线终端或者未来通信网络中的终端设备等，本申请不作限制。

5G基站:是指5G网络中将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，又可以称为接入网设备，网络设备，或者继续演进的节点B(gNB)。主要是提供无线接入服务，调度无线资源给接入终端，提供可靠的无线传输协议和数据加密协议等。网络设备可以为无线接入网中的节点，又可以称为基站，还可以称为RAN节点(或设备)。网络设备可以是LTE中的演进型基站(evolved Node B，eNB或eNodeB)；或者5G网络中的下一代节点B(next generation node B，gNB)或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机或者非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等。可选的，本申请实施例中的网络设备可以包括各种形式的基站，例如：宏基站、微基站(也称为小站)、中继站、接入点、5G之后演进的通信系统中实现基站功能的设备、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备等，还可以包括云接入网(cloud radio access network，C-RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)、NTN通信系统中的网络设备，即可以部署于高空平台或者卫星。本申请实施例对此不作具体限定。
5G核心网:是指在5G网络中为终端设备提供业务支持的核心网(core network，CN)中的设备。用于进行用户接入控制，移动性管理，会话管理，用户安全认证，计费等业务。它有多个功能单元组成，可以分为控制面功能实体和数据面功能实体。认证管理功能(authentication management function，AMF)，负责用户接入管理，安全认证，还有移动性管理。用户面功能(user plane function，UPF)负责管理用户面数据的传输，流量统计等功能。

覆盖增强技术：物理层覆盖增强技术包括且不限于重复(repetition)、多时隙传输块处理(transport block processing over multiple slots，TBoMS)、联合信道估计、跳频，以及天线选择等技术。其中，重复和TBoMS作为增益突出，技术手段明确的两种增强方法，以降低传输速率以及码率的方式使接收机在合并解码时获得能量增益以及编码增益，可以有效的降低链路译码门限，达到覆盖增强的效果。
重复技术：重复技术是地面覆盖增强技术中运用广泛(适用于各种物理信道)的物理层传输手段，通过降低传输速率(等效降低码率)的方式，对同一传输块(transport block,TB)连续发送，可以在接收端获得多段传输合并的能量增益。其合并方式根据每次重复中发送的编码信息的冗余版本(redundancy version，RV)是否相同，在接收端可以分为蔡司合并(chase combining，CC)以及增量冗余(incremental redundancy，IR)合并两种。相比于CC合并在接收端获得的重复发送带来的能量增益，IR合并还可以额外获得不同RV版本合并带来的编码增益，达到降低解码门限的作用。
多时隙传输块处理技术：TBoMS技术是地面覆盖增强中，针对PUSCH信道的覆盖增强提出的一种通过增加编码长度，降低编码头部(header)开销，以相对低的码率进行传输而获得编码增益的覆盖增强技术，该技术的主要影响点在计算传输块大小(transport block size，TBS)流程中增加聚合时隙个数N，作为TBS缩放系数。相比于传统的TBS计算流程，该改动可以使标准中一个TBS的编码比特版本在一个时隙中传输变为在连续的N个时隙中传输。
冗余版本：RV将编码器生成的冗余比特分成若干组，每个RV定义一个传输开始点，首次传送和各次混合自动重传(hybrid automatic repeat request，HARQ)分别使用不同的RV，以实现冗余比特的逐步积累， 完成增量冗余HARQ操作。具体可参阅图2，图2为本申请实施例提供的一种冗余版本RV示意图，如图2所示，TB经过信道编码的数据包括系统位(S)对应的基本数据，以及冗余位(P)对应的冗余数据，这些数据被放在环形缓冲区内。RV0，RV1，RV2，和RV3四个RV版本表示以不同的位置作为起点从环形缓冲区内获取数据。图2中左下角表示按照(0,2,3,2)的冗余版本进行4次重复传输时，每个RV占用的时域资源长度。当前的NR标准中，每次重复传输对应的聚合时隙个数相同，因此每个RV占用的时域资源长度也相同。
一种可能的实现中，重复技术和TBoMS技术可以联合使用。以PUSCH调度场景中的配置授权(configured grant，CG)类型2(type 2)调度为例：聚合时隙数N配置在无线资源控制(radio resource controller，RRC)信令中，具体可以在PUSCH时域资源分配(time domain resource allocation，TDRA)信息单元中(information element，IE)中(与NR传统的重复次数配置在同一位置)，也即是说，聚合时隙个数和重复次数在同一个RRC信令中配置。此后，在上行数据调度中，网络侧通过向UE下发下行控制信息(downlink control information，DCI)激活该配置，UE通过DCI信令中TDRA字段指示到RRC信令中PUSCH_TDRA IE中的行号，获得后续上行PUSCH发送使用的TBoMS聚合时隙个数N以及重复次数M。除了CG Type 2调度场景，TBoMS技术同样支持上行传输的动态调度(dynamic grant，DG)以及CG Type1调度场景。在Type 1调度中，聚合时隙数N以及重复次数M通过RRC信令直接下发给UE，不需要DCI激活。
一种可能的实现中，同一个TBoMS中仅传输一个码块(code block，CB)，即TBoMS中不支持传输块分段。此外，TBoMS传输使用一个RV版本，TBoMS在多次重复传输之间使用不同的RV版本。
基于互联网协议的语音传输(voice over Internet protocol，VoIP)场景中，VoIP PUSCH信道的链路预算具体如表1所示。
表1
表1中表示在PUSCH中，子载波间隔(subcarrier spacing，SCS)为15KHz，物理资源块(Physical Resource Block，PRB)数量为2对应的链路预算。其中最大复合噪声比(composite noise ratio，CNR)为-5.163dB，最小复合噪声比为-23.577dB。在3GPP TS38.821中卫星、终端能力的参数设置下，NTN场景VoIP业务上行数据传输信道的译码门限较高(即是说对传输信道的信噪比需求较高)，很难满足表1所示的链路预算。
一种可能的实现中，可以通过重复技术和TBoMS结合的技术可以提升链路覆盖水平。例如在VoIP场景中，网络侧通过在RRC参数的IE：PUSCH-TimeDomainResourceAllocation中配置UE进行上行传输需要使用的重复次数Mrep，以及TBoMS的聚合时隙个数Ntboms。上述两个参数的取值范围为：Mrep＝{1,2,3,4,7,8,12,16,20,24,28,32}，以及Ntboms＝{1,2,4,8}。具体可参阅图3A，图3A为本申请实施例提供的一种重复传输次数和聚合时隙个数指示信令示意图，如图3A所示，在RRC参数的IE中，配置了“numberofRepetitionsEex-r17”参数的取值，即重复传输次数Mrep的取值。配置了“numberOfSlots-TBoMS-r17”参数的取值，即Ntboms的取值。即，现有标准仅支持网络侧对UE下发RRC参数中已有的参数取值，并且根据关于连续最大传输次数不得超过32个时隙的约束，可知网络侧需要对这两个时域资源分配参数有以下约束：Mrep×Ntboms≤32。
当前，对于VoIP业务的仿真最高使用16ms的传输时间，重复技术和TBoMS结合的传输时长为16ms时，视距(line of sight，LOS)信道下的译码门限为-5.5dB，仅满足LEO600 SET1 30°对应的CNR-5.5dB，其他情况均不满足。
一些场景中，上行数据传输具有传输间隔的限制，VoIP场景中语音包传输间隔可以为20ms。在VoIP业务20ms传输一个语音packet的背景下，基于Mrep×Ntboms≤32的约束，当TBoMS技术与重复技术联合使用，且SCS＝15KHz(1时隙＝1ms)时，网络侧对UE指示的重复次数以及TBoMS聚合时隙个数共有如表2所示的五种组合下发方式：
表2
其中，从终端处理复杂度(译码，接收机处理等)角度考虑，用于调度PUSCH传输的简单的时域资源指示方式为表2中的首行，即仅将传输块重复发送20次，接收端采用CC或IR合并译码。然而仅采用传输块重复发送没有TBoMS带来的额外的编码增益。示例性的，可参阅图3B，图3B为本申请实施例提供的一种重复技术和TBoMS技术联合的性能示意图，其中横轴表示信噪比，纵轴表示误块率(block error rate，BLER)。N表示TBoMS的聚合时隙个数，M表示重复传输次数，MCS表示调制编码方案(modulation and coding scheme)，TBS表示传输块大小(transport block size)。根据图3B所示的示例仿真结果可知，发端仅采用重复技术而不做TBoMS聚合(如N＝1，M＝16)，在三个取值组合中，会有最差的译码性能。N值越大，译码性能越好。发端采用N>1的M、N组合进行传输，覆盖增强的效果更佳。
如表2中所示，当Nthoms>1时，所选择的Mrep与Nthoms的组合，实际上都无法将20ms传输时机完全用于重复技术结合TBoMS聚合以提升覆盖的需求。这将导致覆盖增强无法达到理想效果。
基于此，请参阅图4A，为本申请实施例提供一种数据调度方法示意图，如图4A所示，该方法包括如下流程：
101、网络设备发送第一信息，第一信息用于指示终端设备上行传输的重复传输次数M与T种聚合时隙个数的第一对应关系；M为大于或等于1的整数，T为大于或等于1且小于或等于M的整数。
在本申请实施例中，由网络设备向终端设备发送指示信息，用于指示终端设备上行传输的重复次数M与T种TBoMS的聚合时隙个数的第一对应关系。其中1≤T≤M。通过灵活的方式对TBoMS技术与重复技术联合，使得重复传输是能够更加充分利用传输时机，提升覆盖增强的效果。需要说明的是，本申请实施例中涉及的聚合时隙个数都是指TBoMS的聚合时隙个数，以下不再赘述。
一种可能的实现中，根据对应关系确定的上行传输占用的时长为第一时长，第一时长大于16毫秒。终端设备根据指示信息指示的第一对应关系进行上行传输，可以使得上行传输占用的时长大于16ms。该第一时长可以为20ms，也即是说，采用本申请实施例的指示信息进行上行传输，能够使得终端设备的上行传输充分占用20ms的传输时机。
具体地，本申请实施例可以包括两种实施方式，其中一种实施方式为T＝1，另一种实施方式为T>1。
当T＝1时，即是说重复传输次数M与一种聚合时隙个数存在第一对应关系。
一种可能的实现中，重复传输次数M的取值集合(第二集合)中可以包括5和/或10。也即是说，传输时间间隔20ms，SCS为15KHz时，图4A的方法之前描述的重复传输次数为原始M的集合{1,2,3,4,7,8,12,16,20,24,28,32}中的任意一个，而该可能的实现中，M为第二集合中的任意一个，第二集合＝{1,2,3,4,5,7,8,12,16,20,24,28,32}。对应到图3A中用于指示重复传输次数的“numberofRepetitionsEex-r17”的参数，其取值可以修改为ENUMERATED{n1,n2,n3,n4,n5,n7,n8,n12,n16,n20,n24,n28,n32,spare3,spare2,spare1}。或者第二集合＝{1,2,3,4,7,8,10,12,16,20,24,28,32}，或者第二集合＝{1,2,3,4,5,7,8,10,12,16,20,24,28,32}。同样的，第二集合中新增的10可以以“n10”新增到图3A中所示的参数取值中。
第二集合中包括5和/或10的情况下，当M＝5时，与其存在第一对应关系的聚合时隙个数N＝4，那么第一时长为M*N＝20ms。同样的，当M＝10时，与其存在第一对应关系的聚合时隙个数N＝2，第一时长为M*N＝20ms。这两种第一对应关系都能够使得终端设备的上行传输占用时长(第一时长)刚好能够全部占用VoIP的20ms的传输时机，提升覆盖增强的效果。
又一种可能的实现中，TBoMS的聚合时隙个数的取值集合(第一集合)中包括5。也即是说，图4A 的方法之前描述的聚合时隙个数N为原始N的集合{1,2,4,8}中的任意一个，本申请实施例中，N为第一集合中的任意一个，第一集合＝{1,2,4,5,8}。对应到图3A中用于指示重复传输次数的“numberofRepetitionsEex-r17”的参数，其取值可以修改为ENUMERATED{n1,n2,n4,n5,n8,spare2,spare1}。当N＝5时，与其存在第一对应关系的重复传输次数M＝4，第一时长为M*N＝20ms。
上述第一对应关系是以SCS＝15kHZ为例确定的。当SCS为其他值时，也可以确定其他第一对应关系。例如SCS＝30kHZ，M＝5，聚合时隙个数N＝8，这种情况下每个时隙时长为0.5ms，即第一时长为M*N*0.5＝20ms。M＝10，聚合时隙个数N＝4，第一时长为M*N*0.5＝20ms。即与M＝5存在第一对应关系的为N＝8，与M＝10存在第一对应关系的为N＝4。当N＝5时，M＝8，第一时长为M*N*0.5＝20ms。这些第一对应关系也都能够使得终端设备的上行传输占用时长刚好全部占用VoIP的20ms的传输时机。达成覆盖增强的效果。其他子载波间隔的情况能够以同样的方式确定M＝5和/或10，以及N＝5的第一对应关系。在此不再赘述。
可见，在本申请实施例中，通过增加重复传输次数的取值，或者增加TBoMS的取值，或者同时增加两者的取值，使得重复传输技术与TBoMS技术联合，能够完全占用传输时机，充分利用传输时机进行上行数据的传输，达成更好的覆盖增强的效果。
当T>1时，重复传输次数M与多种TBoMS的聚合时隙个数存在第一对应关系。具体可参阅图4B，图4B为本申请实施例提供的一种第一对应关系示意图，如图4B所示，重复传输次数M中的每次重复传输Repi，都对应一个聚合时隙个数Ni，i＝1,2,3…M。在M个Ni中，至少有两个Ni为不同的值。
在T＞1的情况下，重复传输次数M的取值集合(第二集合)中也可以包括5和/或10，以及TBoMS的聚合时隙个数N的取值集合(第一集合)中也可以包括5。举例来说，当M＝5时，与其存在第一对应关系的聚合时隙个数为{2,4,8,4,2}。同理也可以确定M＝10的情况下的第一对应关系，以及确定T种聚合时隙个数中包括N＝5的情况下的第一对应关系。
在本实施例中，重复传输次数M和T种TBoMS的聚合时隙个数的指示方式如下：
一种可能的实现中，网络设备发送第二信息，第二信息中配置了重复传输次数与聚合时隙个数集合的对应关系；第一信息用于指示第二信息中，重复传输次数M与第一聚合时隙个数集合的第一对应关系，第一聚合时隙个数集合中的不重复元素个数为T。
具体可参阅图4C，图4C为本申请实施例提供的一种重复传输次数与聚合时隙个数集合的对应关系示意图，如图4C所示，每个重复传输次数对应一个或多个聚合时隙个数集合，集合中的不重复元素个数为T。例如M＝3时，对应三个聚合时隙个数集合(元素顺序不同为不同的集合)，分别为集合{8,8,4}、集合{4,8,8}以及集合{8,4,8}。每个集合中包括2个不重复的元素，也即T＝2。通过第二信息将这些重复传输次数与聚合时隙个数集合的对应关系进行配置，再通过第一信息指示重复传输次数M与第一聚合时隙个数集合的第一对应关系。例如指示第一对应关系的序列号或索引号05，表示重复次数M＝4与聚合时隙个数集合{4,4,8,8}的第一对应关系。第二信息中也可以配置新增重复传输次数M＝5和/或10，或者聚合时隙个数包括5的第一对应关系，例如索引号09～11指示的对应关系。
第二信息可以为RRC信令，或者系统信息块(system information block,SIB)，即配置信息通过RRC信令或SIB发送。第一信息可以承载在DCI或RRC信令中。即网络设备通过在DCI或RRC信令中指示第一对应关系的索引号或序列号，激活第一对应关系。
又一种可能的实现中，第一信息承载在RRC信令中，RRC信令中包括重复传输次数M与聚合时隙个数集合的第一对应关系，聚合时隙个数集合中的不重复元素个数为T。
除了上述先配置后激活的方式指示第一对应关系，也可以直接由RRC信令指示第一对应关系。具体地，RRC信令可以显式地指示第一对应关系中的所有参数，包括M以及M对应的完整的聚合时隙个数集合{N1,N2,…,NM}，其中，完整的聚合时隙个数集合中的元素个数＝M(集合中包含的聚合时隙个数的种类T为可以根据聚合时隙个数集合元素获取的参数，可以进行指示，也可以不进行指示)。例如RRC信令中指示了M＝3，与完整的聚合时隙个数集合{4,8,8}，则终端设备可以直接确定存在第一对应关系的为M＝3和集合{4,8,8}。
或者，RRC信令可以显式地指示第一对应关系中的部分参数，另一部分参数根据显示指示的部分参数获取。例如RRC信令中指示了M＝7，并指示了聚合时隙个数集合{2,4}，其中聚合时隙个数N＝2对应第奇数次重复传输次数，N＝4对应第偶数次重复传输次数。即{N1,N2}＝{2,4}两种聚合时隙个数循环与重复传输次数对应。这种情况下RRC并未指示完整的聚合时隙个数集合，但是根据RRC指示的信息，可以确定M＝7对应的完整的聚合时隙个数集合为{2,4,2,4,2,4,2}。同理，RRC信令可以指示完整的聚合时隙个数集 合{N1,N2,…,Nm}＝{2,4,8,4,2}，不指示M，终端设备根据该完整的聚合时隙个数集合可以确定M＝5。
终端设备确定M以及M对应的完整的聚合时隙个数集合之后，可以确定上行传输占用时长(第一时长)，例如M＝5，完整的聚合时隙个数集合＝{2,4,8,4,2}，第一时长＝2+4+8+4+2＝20ms。可以全部占用VoIP的20ms的传输时机。
针对T＝1的情况，也可以通过RRC信令或SIB发送的第二信息进行配置，即图4C中的对应关系示意图可以包括M与单个N或者与单个N组成的集合的对应关系，然后由RRC信令或DCI发送第一信息对该对应关系进行指示或激活。也可以采用RRC信令直接指示M与单个N的对应关系。在此不再赘述。
上述示例是以SCS＝15KHz进行说明的。同样地，当SCS为其他值时，也可以同过上述两种方式指示第一对应关系。例如SCS＝30KHz时，第一信息可以指示M＝4与其对应的完整的聚合时隙个数集合{16,16,4,4}。其他SCS的其他情况本申请实施例在此不做赘述。
102、终端设备接收第一信息，根据第一信息中指示的第一对应关系进行上行传输。相应地，网络设备接收上行传输数据，该上行传输数据为根据第一信息指示的第一对应关系发送的。
终端设备接收到第一信息中的指示的第一对应关系后，根据第一对应关系确定每次重复传输对应的聚合时隙个数，然后按照相应的聚合时隙个数进行对应的重复传输。对应的第一时长＝，这显然比只指示一个M值以及与其对应的一个N值的情况更能获得更多第一时长可能值，因此终端设备采用这种对应关系进行上行传输能够占用全部的传输时机的概率也更大。
网络设备接收终端设备发送的上行传输数据。由于网络设备向终端设备发送了第一指示信息用于指示终端设备如何进行M次重复传输对应的上行传输，因此网络设备接收到上行传输数据对应的编码单元(例如数据包、数据报文等)之后，可以确定如何解码，并获得其中的上行传输数据。
进一步地，前述相关内容中介绍了RV。在重复技术与TBoMS技术联合使用的场景下，可以选择不同的RV循环方式进行重复传输。
(1)RV＝{0,2,3,1}的循环方式。可参阅图4D，图4D为本申请实施例提供的一种RV应用的示意图，如图4D中的(a)所示，RV0，RV2，RV3，RV1循环与7次重复传输次数对应，并且与每次重复传输的聚合时隙个数(包括2,4两种聚合时隙个数)对应。
另外，在本申请实施例中，由于不同次数的重复传输，对应的聚合时隙个数不同，因此4种RV对应占用的时域资源长度也有所不同。具体可参阅图4D中的(b)，RV0对应第1次重复传输，聚合时隙个数为2时隙，则RV0映射到连续的2个时隙；依次类推，RV2映射到连续的4时隙，RV3映射到连续的2个时隙，RV1映射到连续的4个时隙。更广泛地，RV0，RV2，RV3，RV1映射到的连续时隙个数依次根据第M mod 4＝1、M mod 4＝2、M mod 4＝3、M mod 4＝0个重复传输次数对应的聚合时隙个数确定，其中M表示总的重复传输次数。
(2)RV＝{0,3,0,3}的循环方式。可参阅图4E，图4E为本申请实施例提供的另一种RV应用的示意图，如图4E中的(a)所示，RV0，RV3，RV0，RV3循环与7次重复传输次数对应，并且与每次重复传输的聚合时隙个数(包括2,4两种聚合时隙个数)对应。
同样地，RV占用的时域资源长度根据其对应的重复传输次数的聚合时隙个数确定。可参阅图4E中的(b)，RV0对应第1次重复传输，聚合时隙个数为2时隙，则RV0映射到连续的2个时隙。类推可确定RV3映射到连续的4个时隙。更广泛地，RV0映射到的连续时隙个数根据第M mod 4＝1、M mod 4＝3个重复传输次数对应的聚合时隙个数确定，RV3映射到的连续时隙个数根据第M mod 4＝2、M mod 4＝0个重复传输次数对应的聚合时隙个数确定。因为该示例中未采用RV1和RV2，其占用的时域资源长度不在考虑范围。
可选情况下，可以在第一信息或其他信息中指示每个RV占用的时域资源长度，具体可以根据每次重复传输对应的聚合时隙个数确定。以便RV映射的连续时隙个数能够随着灵活变化的聚合时隙个数适应性调整，提升通信过程的可靠性。
另外需要说明的是，上述实施例是以VoIP的传输时机为20ms进行举例说明的。在其他通信业务场景下，对应其他传输时机时，也可以采用本申请实施例的方式确定具有第一对应关系的重复传输次数M和T种TBoMS的聚合时隙个数的第一对应关系，这些对应关系能够使得上行传输占用时长接近或等于其他传输时机。终端设备根据这种第一对应关系进行上行传输，能够尽可能多地占用相关通信业务的传输时机，达成更好的覆盖增强的效果。该说明同样适用于下述实施例，在下述实施例中不在赘述。
可见，在本申请实施例中，通过为重复传输次数M对应至少两种TBoMS的聚合时隙个数，使得不同种类的聚合时隙个数在M次重复传输中进行组合，尽可能多地占用传输时机，以便更多的传输时机能够用 于进行上行数据的传输，达成更好的覆盖增强的效果。
上述实施例都是通过一次性指示重复传输次数M与TBoMS聚合时隙个数的对应关系确定M次重复传输过程中对应的聚合时隙个数。实际上，也可以将M次重复传输进行拆分，并分开指示每部分重复传输对应的聚合时隙个数，进而确定M次重复传输对应的聚合时隙个数。具体地，请参阅图5A，为本申请实施例提供的一种数据调度方法流程图，如图5A所示，该方法包括如下步骤：
201、网络设备发送第一信息，第一信息用于指示终端设备上行传输的多个第一重复传输次数与一种聚合时隙个数的对应关系，多个第一重复传输次数和值为M，M为大于1的整数。在本申请实施例中，由网络设备向终端设备发送指示信息，用于指示多个第一次重复传输次数与一种TBoMS的聚合时隙个数的对应关系，多个第一重复传输次数的和值为M，也即是说分段指示M个重复传输次数，与其对应的聚合时隙个数。
一种可能的实现中，根据对应关系确定的上行传输占用时长为第一时长，第一时长大于16毫秒。该第一时长可以为20毫秒。
具体地，请参阅图5B，图5B为本申请实施例提供的一种第一重复传输次数与聚合时隙个数的对应关系示意图，如图5B所示，假设重复传输次数M被拆分成j个第一重复传输次数，分别为M1、M2…Mj，其中j大于或等于2，且M1+M2+…Mj＝M。其中M1个重复传输对应的聚合时隙个数为N1，M2个重复传输对应的聚合时隙个数为N2，Mj个重复传输对应的聚合时隙个数为Nj。那么根据该对应关系确定的上行传输占用时长(第一时长)为M1*N1+M2*N2+…+Mj*Nj(在SCS＝15KHz的情况下，在其他SCS的情况下，再在每个Mj*Nj的基础上乘以每个时隙的毫秒数即可获得该Mj次重复传输占用时长)。
在本实施例中，多种第一重复传输次数与聚合时隙个数的对应关系可通过以下方式指示：
一种可能的实现中，网络设备发送第二信息，第二信息中配置了重复传输次数与聚合时隙个数的对应关系；第一信息用于指示第二信息中，多个第一重复传输次数中，每个第一重复传输次数与聚合时隙个数的对应关系。
重复传输次数可以为前述描述的{1,2,3,4,7,8,12,16,20,24,28,32}中的任意一个，聚合时隙个数可以为{1,2,4,8}中的任意一个。那么重复传输次数和聚合时隙个数的对应关系可参阅表3：
表3
每种重复传输次数都可以与聚合时隙个数2,4,8对应，且每个重复传输次数与聚合时隙个数的对应关系可以用序列号或索引号进行标识。第二信息中配置了如表3中所示的内容。
然后通过第一信息指示多个第一重复传输次数中，每个第一重复传输次数与聚合时隙个数的对应关系，例如指示M1＝4，N1＝2，M2＝3，N2＝4。具体可以指示这些对应关系在配置内容中的索引号或序列号，例如指示索引号07以及05。
在一些情况下，重复传输次数对应的第二集合中可以包括如前述实施例描述的5和/或10，聚合时隙个数对应的第一集合中可以包括如前述实施例描述的5。例如表3中，配置了M＝5时，分别与聚合时隙个数2,4,8存在对应关系。
一种可能的实现中，第二信息可以为RRC信令或SIB，第一信息可以承载在DCI或RRC信令。
又一种可能的实现中，第一信息承载在RRC信令中，RRC信令中包括多个第一重复传输次数中每个第一重复传输次数与一种聚合时隙个数的对应关系。
即每个第一重复传输次数与聚合时隙个数的对应关系可以由RRC信令直接指示，例如直接指示(M1＝4，N1＝2)以及(M2＝3，N2＝4)两组对应关系，无需额外的信令进行激活。
可选情况下，第一信息还可以用于指示多个第一重复传输次数的执行顺序，例如指示M1为先执行的重复传输次数，那么该上行传输对应的7次重复传输中，先执行的前4次重复传输，对应的聚合时隙个数为2。
202、终端设备接收第一信息，根据第一信息中指示的对应关系进行上行传输。相应的，网络设备接收上行传输数据，该上行传输数据为根据第一信息指示的对应关系发送的。
终端设备接收到第一信息后，根据第一信息中指示的对应关系，确定M次重复传输中，分别按照每个第一传输次数对应的聚合时隙个数进行相应次数的重复传输。在总共包括j个第一传输次数的情况下，对应的第一时长＝M1*N1+M2*N2+…+Mj*Nj。这显然比只指示一个M值与其对应的一个N值的情况更能获得更多第一时长可能值，因此终端设备采用这种对应关系进行上行传输能够占用全部的传输时机的概率也更大。
终端设备接收网络设备发送的上行传输数据。由于网络设备向终端设备发送了第一指示信息用于指示终端设备如何进行M次重复传输对应的上行传输，因此网络设备接收到上行传输数据对应的编码单元(例如数据包、数据报文等)之后，可以确定如何解码，并获得其中的上行传输数据。
可见，在本申请实施例中，可以通过指示多个第一重复传输次数与一种聚合时隙个数的对应关系，完成全部M次重复传输次数对应聚合时隙个数的指示。该过程中，指示的重复传输次数与聚合时隙个数的对应关系与现有协议相同，区别仅在于指示的对应关系数量大于一种。使用该中方法进行指示，可以降低指示过程的复杂度和资源开销，同时能够达成尽量占用传输时机，达成提升覆盖增强效果的作用。
进一步地，一种可能的实现中，本方法的上行传输中，每个第一重复传输次数的重复传输是独立编码的。
具体可参阅图5C，图5C为本申请实施例提供的一种独立编码示意图，如图5C所示，假设网络设备指示了(M1＝4，N1＝2)以及(M2＝3，N2＝4)两组对应关系，则M1对应的前4次重复传输的聚合时隙个数都为2，而M2对应的后3次重复传输的聚合时隙个数都为4。假设将前4次重复传输和后3次重复传输进行独立编码，那么网络设备在接收到终端设备发送的两个编码单元之后，对同一个编码单元能够以统一的聚合时隙个数进行解码，降低接收端解码的复杂度。
可见，在本申请实施例中，上行传输过程中针对多个第一重复传输次数，每个第一重复传输次数的重复传输进行独立编码，可以降低接收端解码的复杂度，提升解码效率，进而提升数据传输效率。
需要说明的是，本申请实施例开与前述图4A～图4E的实施例结合使用。也即是说，第一信息可以同时指示多个第一重复传输次数，且每个第一重复传输次数可以与一种聚合时隙个数对应，也可以与多种聚合时隙个数对应。举例来说，M＝7，M1＝2，N1＝2；M2＝5，对应的聚合时隙个数集合为{4,2,4,2,4}。则M＝7时，对应的聚合时隙个数集合为{2,2,4,2,4,2,4}。这种指示方式也能够降低指示内容的资源占用。假设将M1对应的重复次数和M2对应的重复次数进行独立编码，也能够起到降低接收端解码复杂度，提升数据传输效率的作用。
另外，本申请图4A～图4E，以及图5A～图5C描述的实施例为覆盖增强技术中的重复技术与TBoMS技术联合的技术，这些技术方法还可以与其他覆盖增强技术结合使用。例如与联合信道估计技术结合，将联合信道估计的窗口长度设置为大于或等于或(k表示M次重复传输被分成的k个第一重复传输次数)，那么在M次重复传输对应的连续时隙上，可以进行联合信道估计。或者这些技术方法还可以与调频技术结合使用，在同一次重复传输对应的Ni个时隙上不进行调频，而在不同次数的重复传输对应的时隙上可以进行调频，保证通信质量的同时，获得信道频选增益。与其他技术结合的方式同理，在此不再一一列举。
