一种CG传输时机的配置方法及通信装置
相关申请的交叉引用
本申请要求在2023年02月17日提交中华人民共和国国家知识产权局、申请号为202310157021.3、申请名称为“一种CG传输时机的配置方法及通信装置”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
本申请涉及通信技术领域，尤其涉及一种CG传输时机的配置方法及通信装置。
背景技术
随着无线通信系统的不断发展，数据传输时延不断降低，传输容量越来越大。无线通信系统逐渐渗入一些实时性强、数据容量要求大的业务，比如视频传输、云游戏、扩展现实(extended reality，XR)等。其中，XR是指通过计算机技术和可穿戴设备产生的一个真实与虚拟组合、可人机交互的环境，是增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)、混合现实(mixed reality，MR)等多种形式的统称。
以XR业务为例，接入网设备和终端之间可以通过半静态调度的方式传输XR业务的视频帧，接入网设备可以通过半静态调度为终端配置传输时机。如果视频帧对应的传输时机所能承载的数据量小于视频帧的数据量，会引入额外的调度时延，进而增加XR业务的上行传输时延。
发明内容
本申请提供一种CG传输时机的配置方法及装置，能够降低半静态调度的业务的上行传输时延。
第一方面，本申请实施例提供一种CG传输时机的配置方法，该方法可以由终端执行；或者，也可以由应用于终端中的模块，例如芯片、芯片系统或电路执行；或者，还可以由能实现全部或部分终端功能的逻辑节点、逻辑模块或软件实现，对此不作限定。为了便于描述，下面以由终端执行为例进行说明。终端获得第一参数集合，该第一参数集合包括M个第一参数，M个第一参数中第m个第一参数用于配置M个时段的第m个时段中的多个配置授权CG传输时机，第m个第一参数指示第m个时段中连续的Nm个时间单元，第m个时段中的多个CG传输时机包括Nm个时间单元中的上行时间单元；M为大于1的整数，1≤m≤M，Nm为大于1的整数；终端在第m个时段中的至少一个CG传输时机上，发送上行信息。
通过设计第一参数集合指示多个CG传输时机所在的时间单元，以较少的指示开销，实现对一定时间段内多个CG传输时机的配置，用于半静态调度的业务，能够减少上行传输时延。
在一种可能的设计中，M个时段对应于一个CG周期时段，或者，M个时段中的一个时段对应于一个CG周期时段。这样的设计实现了在CG周期时段中配置多个CG传输时机，可以周期性地增加半静态调度的资源，能够减少上行传输时延，有助于提升上行传输的稳定性。
在一种可能的设计中，N个CG传输时机中一个CG传输时机对应的混合自动重传请求HARQ的重传时长小于一个CG周期时段的时长。这样的设计减少了HARQ的重传时长，可以支持一个CG周期时段内不同CG传输时机对HARQ资源的重复利用，能够节省HARQ资源，提升HARQ资源的利用率。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
本申请实施例涉及如下的至少一个(项)，指示一个(项)或多个(项)。其中，多个(项)，是指两个(项)或两个(项)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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。另外，应当理解，尽管在本申请实施例中可能采用术语第一、第二等来描述各对象、但这些对象不应限于这些术语。这些术语仅用来将各对象彼此区分开。
本申请实施例如下描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何方法或设计方案不应被解释为比其 它方法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。
本申请实施例提供的技术可以应用于各种通信系统，图1为示出了一种可能的、非限制性的通信系统示意图。如图1所示，通信系统1000包括无线接入网(radio access network，RAN)100和核心网(core network,CN)200。RAN 100包括至少一个RAN节点(如图1中的110a和110b，统称为110)和至少一个终端(如图1中的120a-120j，统称为120)。RAN100中还可以包括其它RAN节点，例如，无线中继设备和/或无线回传设备(图1中未示出)等。终端120通过无线的方式与RAN节点110相连。RAN节点110通过无线或有线方式与核心网200连接。RAN节点110用于帮助终端实现无线接入。核心网200中的核心网设备与RAN 100中的RAN节点110可以分别是不同的物理设备，也可以是集成了核心网逻辑功能和无线接入网逻辑功能的同一个物理设备。可选的，RAN节点110还可以连接互联网300，或通过核心网200与互联网300连接。
RAN 100可以为第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统，例如，第四代(4th generation，4G)、第五代(5th generation，5G)移动通信系统、或面向未来的演进系统(例如6G移动通信系统)。RAN 100还可以是开放式接入网(open RAN，O-RAN或ORAN)、云无线接入网络(cloud radio access network，CRAN)或者无线保真(wireless fidelity，WiFi)系统。RAN100还可以是以上两种或两种以上系统融合的通信系统。其中，4G移动通信系统包括长期演进(long term evolution，LTE)系统、5G移动通信系统包括新无线(new radio，NR)系统。
通信系统1000中的多个RAN节点110可以为同一类型的节点，也可以为不同类型的节点。在一些场景下，RAN节点110和终端120的角色是相对的，例如，图1中网元120i可以是直升机或无人机，其可以被配置成移动基站，对于那些通过网元120i接入到RAN 100的终端120j来说，网元120i是基站；但对于基站110a来说，网元120i是终端。RAN节点110和终端120有时都称为通信装置，例如图1中网元110a和110b可以理解为具有基站功能的通信装置，网元120a-120j可以理解为具有终端功能的通信装置。
下面对RAN节点和终端进行详细说明。
(1)RAN节点
在一种可能的场景中，RAN节点，也可以称为接入网设备，RAN实体或接入节点或网络设备等，构成通信系统的一部分，用以帮助终端实现无线接入。RAN节点可以是基站(base station，BS)、演进型基站(evolved NodeB，eNB)、接入点(access point，AP)、发送接收点(transmission reception point，TRP)、下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站或未来移动通信系统中的基站、或WiFi系统中的接入节点等。RAN节点可以是宏基站(如图1中的110a)、微基站或室内站(如图1中的110b)、中继节点或施主节点、或者是CRAN场景下的无线控制器。可选的，RAN节点还可以是服务器，可穿戴设备，车辆或车载设备等。例如，车辆外联(vehicle to everything，V2X)技术中的接入网设备可以为路侧单元(road side unit，RSU)。本申请中的RAN节点的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平台)上实例化的虚拟化功能来实现。本申请中的RAN节点还可以是能实现全部或部分RAN节点功能的逻辑节点、逻辑模块或软件。
在另一种可能的场景中，由多个RAN节点协作协助终端实现无线接入，不同RAN节点分别实现接入网设备的部分功能。接入网设备包括集中式单元(central unit，CU)、分布式单元(distributed unit，DU)和无线单元(radio unit，RU)。CU和DU可以是单独设置，或者也可以包括在同一个网元中，例如基带单元(baseband unit，BBU)中。RU可以包括在射频设备或者射频单元中，例如包括在射频拉远单元(remote radio unit，RRU)、有源天线处理单元(active antenna unit，AAU)或远程射频头(remote radio head，RRH)中。
可以理解，在不同系统中，CU(或CU-CP和CU-UP)、DU或RU也可以有不同的名称，但是本领域的技术人员可以理解其含义。例如，在ORAN系统中，CU也可以称为O-CU(开放式CU)，DU也可以称为O-DU，CU-CP也可以称为O-CU-CP，CU-UP也可以称为O-CU-UP，RU也可以称为O-RU。为描述方便，本申请中以CU，CU-CP，CU-UP、DU和RU为例进行描述。本申请中的CU(或CU-CP、CU-UP)、DU和RU中的任一单元，可以是通过软件模块、硬件模块、或者软件模块与硬件模块结合来实现。

本申请实施例中“向…(终端)发送信息”可以理解为该信息的目的端是终端，可以包括直接或间接的向终端发送信息。“从…(终端)接收信息”可以理解为该信息的源端是终端，可以包括直接或间接的从终端接收信息。信息在信息发送的源端和目的端之间可能会被进行必要的处理，例如格式变化等，但目的端可以理解来自源端的有效信息。本申请中类似的表述可以做类似的理解，在此不再赘述。
本申请实施例描述的通信系统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。
下面先对本申请实施例所涉及的相关术语进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
(1)半静态调度
接入网设备为终端调度上下行传输资源的方式可以有两种，即动态调度和半静态调度。在动态调度中，接入网设备可以通过控制信道向终端发送控制信息，从而为终端分配数据信道的传输参数。其中，控制信道比如为物理下行控制信道(physical downlink control channel，PDCCH)，控制信息比如可以为下行控制信息(downlink control information，DCI)；数据信道比如可以为物理下行共享信道(physical downlink shared channel，PDSCH)或物理上行共享信道(physical uplink shared channel，PUSCH)。示例性地，控制信息可以指示数据信道所映射的时频位置(比如，数据信道所映射的时域符号、频域资源块(resource block，RB))，进而接入网设备和终端在该时频位置上，可以通过数据信道传输下行信息(比如PDSCH携带的数据)和/或上行信息(比如PUSCH携带的数据)。
在半静态调度中，接入网设备可以为终端分配周期性的上下行传输资源。其中，用于分配上行传输资源的半静态调度可以称为配置授权(configured grant，CG)，用于分配下行传输资源的半静态调度可以称为半持续调度(semi-persistent scheduling，SPS)。进一步地，针对于上行：用于进行一次上行传输的传输资源可以称为一个上行传输时机(或简称传输时机)，上行传输时机也可以替换为其它可能的描述，比如CG传输时机、CG传输机会、基于CG的PUSCH机会、基于CG的PUSCH时机、或CG PUSCH。针对于下行：用于进行一次下行传输的传输资源可以称为一个下行传输时机(或简称传输时机)，下行传输时机也可以替换为其它可能的描述，比如SPS传输时机、SPS资源、PDSCH资源、PDSCH机会、 或PDSCH时机。
从时域上看，传输时机可以包括一个符号或连续的多个符号。当传输时机包括多个符号时，这多个符号可以位于同一个时隙，或者也可以位于多个时隙；类似地，当传输时机所包括的多个符号位于多个时隙时，这多个时隙可以位于同一个系统帧，或者也可以位于多个系统帧。
(2)CG
在CG机制中，网络设备通过只需要通过无线资源控制(radio resource control，RRC)消息或者PDCCH分配或指定一次上行传输资源，而后就可以周期性地重复使用相同的时频资源。具体来说，CG可以支持两种类型，分别为CG类型1(CG type1)和CG类型2(CG type 2)，CG类型1和CG类型2的区别在于激活传输时机的方式不同。
CG类型1是指，网络设备通过RRC消息配置至少一套CG传输时机中每套CG传输时机对应的CG周期(或称为CG周期时段)、CG时机的时域资源和频域资源。也就是说，周期参数和用于指示具体的时频位置的参数均承载于RRC消息。终端一旦正确接收到RRC消息，配置就立即生效(也就是说，配置即激活)。
CG周期可以是NR支持的2个符号，7个符号或者14个符号的整数倍。符号的长度与子载波间隔有关，比如当子载波间隔为30kHz时，时隙的长度为0.5ms，一个时隙包括14个符号，此种情形下，CG周期可以为2个符号，7个符号或者(1～1280)*14个符号，即最小的CG周期为0.5/7ms，最大的CG周期为640ms。
如图2A示意，针对CG类型1的一套CG传输时机，网络设备发送的RRC消息中可以包括CG周期(periodicity)；一个CG传输时机在一个时隙内的时域资源(timeDomainAllocation)，如一个CG传输时机包括的符号数量；一个CG传输时机在一个时隙内的频域资源(frequencyDomainAllocation)；mcsAndTBS，该mcsAndTBS指示在CG传输时机上传输上行信息采用的调制和编码速率(modulation and code scheme，MCS)以及传输块的大小(transport Block size，TBS)。
示例性地，RRC消息还可以包括它可能的参数，比如timeReferenceSFN、timeDomainOffset、S等。其中，timeReferenceSFN用于指示首个CG传输时机的起始时间对应的SFN，timeDomainOffset用于指示首个CG传输时机的起始时间对应的时隙编号，S用于指示首个CG传输时机的起始时间对应的符号编号。
CG类型2类似于SPS，即网络设备可以通过RRC消息配置至少一套CG传输时机对应的CG周期、时域资源分配(time domain resource assignment)、频域资源分配(frequency domain resource assignment)等参数，然后，针对至少一套传输时机中的每套传输时机，网络设备可以通过DCI(承载于PDCCH)激活并指示该套传输时机中首个传输时机的时频位置，该DCI也可以称为激活DCI，承载于PDCCH。
如图2B示意，针对CG类型2的一套CG传输时机，DCI中包括该套CG传输时机对应的CG周期，时域资源分配(time domain resource assignment，TDRA)字段和频域资源分配(frequency domain resource assignment，FDRA)字段，以及MCS。其中，TDRA字段指示一个CG传输时机在一个时隙内的时域资源(timeDomainAllocation)，FDAR字段指示一个CG传输时机在一个时隙内的时频域资源(timeDomainAllocation)。可选的，TDRA字段中包括scheduling offset K2(如下简称为K2)、起始和长度指示值(start and length indicator value，SLIV)。其中，K2指示激活DCI和该套CG传输时机中的首个CG传输时机之间的时隙(slot)偏移值，例如，K2＝0时，表示首个CG传输时机与PDCCH在同一个时隙上，K2＝1时，表示首个CG传输时机位于PDCCH后面一个时隙上。SLIV指示首个CG传输时机的起始符号位置和时间长度。MCS指示在CG传输时机上传输上行信息采用的调制和编码速率。
另外，对应于业务的上行传输场景，网络设备可以根据业务信息，确定业务的周期和数据量大小，进而确定前述至少一套CG传输时机对应的CG周期、时频域资源配置等参数。示例性地，业务信息可以包括终端的服务请求，服务质量(quality of service，QoS)流建立请求，或终端上报的辅助信息等。
(3)数据帧
数据帧也可以称为数据片(slice)、数据块(tile)。针对于某一业务(比如XR业务)，该业务可以包括至少一个数据帧，或者至少一个数据片，或者至少一个数据块，或者至少一个协议数据单元(protocol data unit，PDU)集合(PDU set)，一个PDU set中包含至少一个数据帧、至少一个数据片或至少一个数据块中的一项或多项。
本申请实施例中，数据帧可以为视频帧、音频帧或者其它可能的帧，具体不做限定。下文中将以数 据帧为视频帧为例进行描述。
视频可以是由一张张连贯起来的图像(或者说图片、照片等)连续播放组成的，当一秒钟有24张图像快速播放，人眼就会认为这是连续的画面(即视频)。帧率是指每秒钟播放的图像数量，比如当帧率为30帧每秒钟(30fps)时，表示每秒钟播放30张图像，当帧率为60(frame per second，FPS)时，表示每秒钟播放60张图像，以此类推。一个视频帧可以理解为一张图像，即一个视频帧可以包括一张图像对应的多个数据包，一个视频帧的数据量即为该视频帧所包括的多个数据包的数据量之和。帧率和周期互为倒数，当帧率为60帧时，视频帧的传输周期为1000/60＝50/3毫秒(ms)，约等于16.67ms。以帧率为60帧为例，参见图3所示，为多个视频帧的传输示意图，图3中的视频帧1至视频帧4为连续的4个视频帧。可选的，视频帧的传输周期(16.67ms)也可以理解为XR业务的一种业务周期。
以XR业务为例，接入网设备和终端之间可以通过半静态调度的方式传输XR业务的视频帧。终端在CG传输时机上向接入网设备发送XR业务的上行信息，接入网设备在SPS传输时机上向终端发送XR业务的下行信息。
对于不同的XR业务，其上行和下行的业务模型通常也不相同。例如VR的场景内容显示的变化是由姿态或位置(动作)引发的，VR的上行信息的主要是位置和姿态信息，数据量通常为几十kbps。下行信息的主要是渲染后的视频流，数据量比较大，可达几十到上百Mbps。与VR不同的是，AR的场景内容显示的变化是由注视聚焦目标的变化以及位置和注视点之间空间关系变化(动作)引发的，AR的上行信息包括感知所需要的视觉信息，例如清晰和稳定的图片或者视频流(视频帧)，或者一些抽取出的环境特征信息，数据量较大。由上述内容可知，XR业务尤其是AR业务对上行传输的速率需求较高。
目前在授权频谱中，一个CG周期内只能配置一个CG传输时机，视频帧的数据量大于一个CG传输时机所能承载的数据量。对于超出CG传输时机的数据量，如果终端需要向接入网设备发送缓存状态报告(buffer status report，BSR)以请求更多的上行传输资源，BSR涉及的解析、调度和组包等操作会造成更大的时延，影响视频帧的正常传输，无法满足AR业务对上行传输的速率需求；如果终端不发送BSR，接入网设备侧无法感知超出CG传输时机的数据量，导致视频帧传输出错。
而在非授权频谱中，虽然支持一个CG周期内配置一个或多个CG传输时机，但要求多个CG传输时机占用连续的时续，导致不同CG周期中包括的CG传输时机的数量可能不同。如图4示意，以U表示上行时隙，D表示下行时隙。在第一CG周期中，假设第一个CG传输时机为上行时隙2，由于上行时隙7和上行时隙2之间不连续，因此，CG传输时机只包括上行时隙2。在第二CG周期中，假设第一个CG传输时机为上行时隙2，由于上行时隙3和上行时隙7之间不连续，因此，CG传输时机只包括上行时隙2和上行时隙3。在视频帧的上行传输场景中，这样的设计可能出现部分CG周期中的CG传输时机的数据量小于视频帧，而导致视频帧的传输时延变大或传输出错。
基于此，本申请实施例提供一种CG传输时机的配置方案，可以实现在一个CG周期中配置多个CG传输时机，两个相邻CG传输时机所在的时隙可以连续或者不连续，多个CG周期中的CG传输时机的数量相同。该方案能够应用于授权频谱或者非授权频谱的场景中，可以降低例如XR业务等半静态调度业务的上行传输时延，以及提升上行传输的准确性。下面进一步结合实施例，以接入网设备与终端之间的交互为例对该方案进行详细说明。
可以理解，本申请下述提供的方法中是以接入网设备和终端设备作为交互示意的执行主体为例来示意，但本申请并不限制交互示意的执行主体。例如，本申请中的接入网设备也可以是应用于接入网设备的模块(例如芯片、芯片系统、或处理器)，还可以是能实现全部或部分接入网设备功能的逻辑节点、逻辑模块或软件；本申请中的终端设备也可以是应用于终端设备的模块(例如芯片、芯片系统、或处理器)，还可以是能实现全部或部分终端设备功能的逻辑节点、逻辑模块或软件。
实施例一
如图5示意一种通信方法，该通信方法也可以替换描述为CG传输时机的配置方法，该通信方法主要包括如下步骤。
S501，接入网设备向终端发送第一参数集合。
其中，第一参数集合包括M个第一参数，M个第一参数中第m个第一参数用于配置M个时段的第m个时段中的多个配置授权CG传输时机，第m个第一参数指示第m个时段中连续的Nm个时间单 元，第m个时段中的多个CG传输时机包括Nm个时间单元中的上行时间单元；M为大于1的整数，Nm为大于1的整数，1≤m≤M，或者也可以理解为m取1到M的整数。
可以理解的是，前述上行时间单元指的是用于上行传输的时间单元，该时间单元可以是上行子帧、上行时隙、上行符号、或者可灵活配置上行或下行的时间单元，如灵活时隙或灵活子帧中的时间单元。
可选的，m的取值不同，对应的Nm的取值可以相同或者不相同，Nm个时间单元中的上行时间单元的数量相同。通过这样的设计，可以实现M个时段的每个时段中的CG传输时机的数量相同。示例性的，M个时段中一个时段可以为一个视频帧的传输周期(16.67ms)，一方面，这样的设计增加了一个视频帧对应的CG传输时机的数量，能够避免或减少额外的调度时延，提升XR业务的上行传输速率。另一方面，这样的设计可以保证每个视频帧的传输周期对应相同数量的CG传输时机，有利于XR业务的稳定传输。
在一种可能的实现中，接入网设备可以根据TDD format和M个时段的起始位置确定Nm的取值。其中，TDD format指的是时分双工(time-division fuplex，TDD)格式(format)中的上行时间单元/下行时间单元的配比。
例如，图6示意一种上行时间单元/下行时间单元的配比方式，“U”表示上行时间单元，“D”表示下行时间单元。M个时段的起始位置为时间单元0，M个时段中的一个时段为16.67ms，M为3，M个时段总长50ms，1ms对应一个上行时间单元或下行时间单元。其中，第1个时段(0～16.67ms)中的时间单元2、3、7、8、12、13为上行时间单元，第2个时段(16.67ms～33.33ms)中的时间单元17、18、22、23、27、28为上行时间单元，第3个时段(33.33～50ms)中的时间单元37、38、42、43、47、48为上行时间单元。为保证每个时段中的CG传输时机数量相同，接入网设备可以确定N1为8，表示第1个时段的CG传输时机位于前8个时间单元，或者也可以理解为：第0～16.67ms内有3个有效(valid)的CG传输时机，包括时间单元2、3、7。类似地，接入网设备可以确定N2为6，表示第2个时段的CG传输时机位于前6个时间单元，或者也可以理解为：第16.67ms～33.3ms内有3个有效(valid)的CG传输时机，包括时间单元17、18、22。接入网设备可以确定N3为9，表示第3个时段的CG传输时机位于前6个时间单元，或者也可以理解为：第16.67ms～33.3ms内有3个有效(valid)的CG传输时机，包括时间单元37、38、42。
可选的，接入网设备可以根据CG类型，确定第一参数集合的发送方式。
例如，在CG类型1的场景中，接入网设备可以向终端发送包括第一参数集合的RRC消息。该RRC消息可以是一条单独用于传输第一参数集合的信令；或者，该RRC消息可以是前述用于配置至少一套CG传输时机的信令，即也可以理解为：接入网设备在包含至少一套CG传输时机的RRC消息中，新增加了第一参数集合。实际应用时，还可以在RRC消息中定义一个字段(如cg-nrofSlot-List)来指示第一参数集合。终端侧可以根据RRC消息中激活的一套CG传输时机和第一参数集合，确定M个时段的每个时段中的多个CG传输时机。
又如，在CG类型2的场景中，接入网设备可以向终端发送包括第一参数集合的DCI或称PDCCH。该DCI可以是一条单独用于传输第一参数集合的信令；或者，该DCI可以是前述用于激活一套CG传输时机的信令，即也可以理解为：接入网设备在用于激活一套CG传输时机的DCI中，新增加了第一参数集合。实际应用时，还可以在DCI中定义一个字段(如cg-nrofSlot-List)来指示第一参数集合。终端侧可以根据DCI中激活的一套CG传输时机和第一参数集合，确定M个时段的每个时段中的多个CG传输时机。或者可选的，接入网设备可以向终端发送包括第一参数集合的RRC，例如该RRC可以是一条单独用于传输第一参数集合的信令；或者，该RRC是用于配置至少一套CG传输时机的信令，接入网设备在每套CG传输时机的配置参数中添加对应的第一参数集合(cg-nrofSlot-List)。终端侧可以根据RRC消息中激活的一套CG传输时机的配置参数，确定M个时段的每个时段中的多个CG传输时机。
可以理解的是，在第一参数集合表示为cg-nrofSlot-List的情况下。一种可能的设计中，第一参数集合中的M个第一参数从0开始编号，cg-nrofSlot-List中的第m个第一参数可以表示为cg-nrofSlot-List[m-1]，对应的Nm也可以替换描述为cg-nrofSlot-List[m-1]。另一种可能的设计中，第一参数集合中的M个第一参数从1开始编号，cg-nrofSlot-List中的第m个第一参数可以表示为cg-nrofSlot-List[m]，对应的Nm也可以替换描述为cg-nrofSlot-List[m]。此外可以理解的是，上述M个时段和CG周期时段存在一定的对应关系。
在一种可能的设计中，M个时段中的一个时段对应于一个CG周期时段。接入网设备通过第一参数集合，可以同时配置M个CG周期时段中的CG传输时机。可选的，CG周期时段也可以替换描述为CG周期，即也可以理解为：M个时段中的一个时段为一个CG周期，本申请实施例对此不予限制。类似地，每M个CG周期时段中CG传输时机的配置均可参照接入网设备指示的前述M个CG周期时段中CG传输时机的配置理解，本申请实施例对此不进行赘述。以XR业务的上行传输为例，M个时段中一个时段可以是一个视频帧的传输周期(16.67ms)，则一个CG周期时段可以为16.67ms。
在另一种可能的设计中，M个时段对应于一个CG周期时段。接入网设备通过第一参数集合，可以配置一个CG周期时段中的多个CG传输时机。其余的CG周期时段中CG传输时机的配置均可参照该一个CG周期时段中CG传输时机的配置理解，本申请实施例对此不进行赘述。以XR业务的上行传输为例，M个时段中一个时段可以是一个视频帧的传输周期(16.67ms)，则一个CG周期时段可以为M*16.67ms。例如M为3时，一个CG周期时段为50ms，一个CG周期时段包括3个XR业务周期。
S502，终端根据第一参数集合，确定第m个时段中的多个CG传输时机。
A1，在CG类型1的场景中，终端可以利用如下关系式(1)确定M个时段中至少一个时段中的第一个CG传输时机的起始符号；进而，终端根据第一参数集合和至少一个时段中的第一个CG传输时机的起始符号，可以确定M个时段的每个时段中的每个CG传输时机的起始符号；并且，终端也可以从接入网设备下发的RRC消息中获取CG传输时机的时域资源、频域资源。
例如，以第一时段指示M个时段中的第一个时段或者第n个时段，可以理解的是，第一时段中的第一个CG传输时机的起始符号满足关系式(1)：
SFN1×TSnum×Snum+TS1×Snum+S1＝Int[RSFN×TSnum×Snum+RTS×Snum+RS+I×P]
modulo(1024×TSnum×Snum)；(1)
下面结合(1-a)～(1-f)对关系式(1)中的参数进行详细说明。

例如，在M个时段对应于一个CG周期时段的情况下，第一时段为M个时段中的第一个时段，I为一个CG周期时段的编号，P为一个CG周期时段的时长。此情况下，第m个时段中的第一个CG传输时机的起始符号相对于第一时段中的第一个CG传输时机的起始符号的偏移量为M个时段中m-1个时段的时长的取整结果。例如将前述偏移量表示为offset，第m个时段中的第一个CG传输时机的起始符号对应的offsetm＝int[(m-1)*L]，L表示一个时段的时间长度，简称该时段的时长。
又如，第一时段为M个时段中第m个时段，I为第m个时段的编号，P为第m个时段的时长。

(1-f)：modulo表示取模运算。(1024×TSnum×Snum)表示的是1024个系统帧，或者是以符号为单位的1024个系统帧的时间长度。前述(1-a)～(1～e)中涉及的参数的取值范围为1024个系统帧， 例如SFN1、RSFN的编号的取值范围可以是0～1023。
可选的，本申请实施例中提到的1024个系统帧也可以被看作一个超帧，也即作为一种示例，一个超帧包括1024个系统帧。可以理解的是，如果未来对于超帧的定义不是包括1024个系统帧，上述关系式中的“1024”也可以被替换为其他的固定值或者变量，本申请实施例对此不予限定。
此外可以理解的是，本申请实施例中的系统帧的编号、时隙编号、符号编号、时段的编号、CG周期时段的编号等编号的范围均可以统一从0或其他的正整数开始。本申请实施例对此不予限制。
以XR业务场景为例，M个时段中的一个时段为一个业务周期(16.67ms)。假设子载波间隔为30kHz，RFS＝0，RTS＝0，Int[]表示向上取整。
一种可能的实现中，在一个CG周期时段为3个业务周期(50ms)，第一时段为M个时段中的第一个时段的情况下，M＝3。首先将I＝0，P＝50ms，代入关系式(1)确定M个时段中第1个时段中的第一个CG传输时机的起始位置为0ms。然后，结合前述offsetm可以确定第2个时段中的第一个CG传输时机的起始位置为17ms，以及第3个时段中的第一个CG传输时机的起始位置为34ms。最后，终端可以根据第一参数集合，确定每个时段中其余的CG传输时机。为便于理解，本申请实施例在图7A中以不同的图案填充区分确定不同CG传输时机的先后顺序。
另一种可能的实现中，第一时段为M个时段中的第m个时段的情况下，以M＝3，一个CG周期时段为三个业务周期(50ms)为例，首先将I＝0，P＝16.67ms，代入关系式(1)可以得到M个时段中第1个时段中的第一个CG传输时机的起始位置为0ms，第2个时段中的第一个CG传输时机的起始位置为17ms，以及第3个时段中的第一个CG传输时机的起始位置为34ms。然后，终端可以根据第一参数集合，确定每个时段中其余的CG传输时机。为便于理解，本申请实施例在图7B中以不同的图案填充区分确定不同CG传输时机的先后顺序。

如图10示意一种通信方法，该通信方法也可以替换描述为CG传输时机的配置方法，该通信方法主要包括如下步骤。
S1001，接入网设备向终端发送第四参数集合。
其中，第四参数集合包括N个第四参考CG传输时机的资源参数，N个第四参考CG传输时机中第n个第四参考CG传输时机的资源参数用于配置CG周期时段中，N个CG传输时机中的第n个CG传 输时机；N为大于1的整数，1≤n≤N。
可选的，N个第四参考CG传输时机位于一个参考CG周期时段中，该参考CG周期时段与待配置的CG周期时段的时长相同。参考CG周期时段中的N个第四参考CG传输时机的资源参数与待配置的CG周期时段中N个CG传输时机一一对应。
可选的，接入网设备可以向终端发送包括第四参数集合的RRC消息。该RRC消息可以是一条单独用于传输第四参数集合的信令；或者，该RRC消息可以是用于配置至少一套CG传输时机的信令，该RRC消息中可以包括第四参数集合。终端侧可以根据RRC消息中激活的一套CG传输时机和第四参数集合，确定M个时段的每个时段中的多个CG传输时机。
示例性地，第n个第四参考CG传输时机的资源参数指示第n个第四参考CG传输时机的起始符号，第n个第四参考CG传输时机的起始符号可以用于配置CG周期时段中，N个CG传输时机中的第n个CG传输时机的起始符号。
S1002，终端根据第四参数集合，确定CG周期时段中的N个CG传输时机。
例如，在CG类型1的场景中，终端可以利用如下关系式(5)确定第n个CG传输时机的起始符号，并且，终端也可以从接入网设备下发的RRC消息中获取CG传输时机的时域资源、频域资源。可选的，CG周期时段中包括N个CG传输时机，第n个CG传输时机的起始符号满足关系式(5):
SFNn×TSnum×Snum+TSn×Snum+Sn＝Int[RSFNn×TSnum×Snum+RTSn×Snum+RSn+I×P]
modulo(1024×TSnum×Snum)；(5)
其中，RSFNn、RTSn、RSn对应于第n个第四参考CG传输时机。RSFNn为第n个第四参考CG传输时机的起始符号所在的系统帧的编号，也可以被替换描述为timeReferenceSFN[n]；RTSn为第n个第四参考CG传输时机的起始符号所在的时隙的编号，也可以被替换描述为timeDomainOffset[n]；RSn为第n个第四参考CG传输时机的起始符号的编号。

此外可以理解的是，系统帧、时隙、符号可以从0开始编号，如n＝1，第1个第四参考CG传输时机的起始符号所在的系统帧的编号表示为RSFN1＝0，或者timeReferenceSFN[1]＝0。或者，系统帧、时隙、符号也可以从1开始编号，如n＝1，第1个第四参考CG传输时机的起始符号所在的系统帧的编号表示为RSFN1＝1，或者timeReferenceSFN[1]＝1。本申请实施例对此不予限制。可选的，在系统帧、时隙、符号从0开始编号的情况下，可以统一将关系式(5)中部分参数的下角标从n替换为n-1。例如，将SFNn替换为SFNn-1。
又如，在CG类型2的场景中，终端可以利用如下关系式(6)确定第n个CG传输时机的起始符号，并且，终端也可以从接入网设备下发的DCI中获取激活的CG传输时机的时域资源、频域资源。可选的，CG周期时段中包括N个CG传输时机，第n个CG传输时机的起始符号满足关系式(6):
SFNn×TSnum×Snum+TSn×Snum+Sn＝Int[SFNstart[n]×TSnum×Snum+TSstart[n]×Snum+
Sstart[n]+I×P]modulo(1024×TSnum×Snum)；(6)
其中，SFNstart[n]、TSstart[n]、Sstart[n]对应于第n个第四参考CG传输时机。其中，SFNstart[n]为第n个第四参考CG传输时机的起始符号所在的系统帧的编号，也可以替换描述为timeReferenceSFN[n]。TSstart[n]为第n个第四参考CG传输时机的起始符号所在的时隙的编号，TSstart[n]也可以替换描述为slot number in the frame[n]，即TSstart[n]是在一个系统帧内的时隙编号。Sstart[n]为第n个第四参考CG传输时机的起始符号的编号，Sstart[n]也可以替换描述为symbol number in the slot[n]，即Sstart[n]是在一个时隙内的符号编号。
SFNn、TSn、Sn对应于第n个CG传输时机。SFNn、TSn、Sn、TSnum、Snum、Int[]、I、P、modulo等均可参照S902中的描述理解，本申请实施例对此不进行赘述。
此外可以理解的是，系统帧、时隙、符号可以从0开始编号，如n＝1，第1个第四参考CG传输时机的起始符号所在的系统帧的编号表示为SFNstart[1]＝0，或者timeReferenceSFN[1]＝0。或者，系统帧、时隙、符号也可以从1开始编号，如n＝1，第1个第四参考CG传输时机的起始符号所在的系统帧的编号表示为SFNstart[1]＝1，或者timeReferenceSFN[1]＝1。本申请实施例对此不予限制。可选的，在系统帧、时隙、符号从0开始编号的情况下，可以统一将关系式(6)中部分参数的[n]替换为[n-1]，例如将TSstart[n]替换为TSstart[n-1]；以及将关系式(6)中部分参数的下角标从n替换为n-1。例如，将SFNn替换 为SFNn-1。
S1003，终端在CG周期时段中的至少一个CG传输时机上，发送上行信息。
其中，该上行信息可以包括承载于PDSCH的上行数据。示例性地，在XR业务场景中，该上行信息可以包括数据帧，如视频帧。
本申请实施例提供的上述实施例三，引入多个参考CG传输时机的资源参数配置，能够加快确定一个CG周期内的多个CG传输时机的时域位置，降低上行传输时延。
此外，本申请实施例还提供一种重传方法，该重传方法可以应用于上述实施例一至实施例四中的任意一个实施例。如图11示意，该重传方法主要包括如下步骤。
S1101，接入网设备向终端发送第一重传配置信息，第一重传配置信息用于配置一个CG周期时段中N个CG传输时机对应的重传资源的占用时长，第一重传配置信息指示至少一种时长；N个CG传输时机中的一个CG传输时机对应的重传资源的占用时长为至少一种时长中的一种时长，至少一种时长中任意一种时长小于一个CG周期时段的时长。
可以理解的是，一个CG周期时段中的至少两个CG传输时机对应的重传资源相同，该至少两个CG传输时机中相邻两个CG传输时机之间的间隔大于或等于重传资源的占用时长。这样的设计可以减少CG传输时机所需占用的重传资源的数量，避免长时间占用重传资源而导致不必要的资源浪费。
可选的，前述重传资源可以是混合自动重传请求HARQ进程(process)，重传资源的占用时长也可以替换描述为HARQ的重传时长。
可选的，对应于上述实施例，当一个CG周期包括M个时段时，一个重传资源的占用时长可以为M个时段中一个时段的时长。以XR业务场景为例，M个时段中一个时段对应于一个业务周期(视频帧的周期)，可以理解一个CG周期包括M个业务周期，一个重传资源的占用时长可以为一个业务周期的时长，例如16.67ms。
作为示例，图12A示意出，一个CG周期为50ms，每个16.67ms内有3个CG传输时机，一个CG周期总共包括9个CG传输时机。假设第一个16.67ms中的第一个CG传输时机对应HARQ进程0，在一个重传资源的占用时长为16.67ms的情况下，第二个16.67ms中的第一个CG传输时机也可以对应HARQ进程0。以此类推，一个CG周期时段中的9个CG传输时机，只需要配置3个HARQ进程。这样的设计相较于配置HARQ进程的占用时长大于CG周期时段的情况，减少了HARQ进程的占用数量，避免长时间占用HARQ进程而导致不必要的资源浪费。示例性地，图12B中示出了配置HARQ进程的占用时长大于CG周期时段(50ms)的情况中，需要配置9个HARQ进程(0～8)。
类似地，在一个CG周期为16.67ms的情况下，一个重传资源的占用时长可以是15ms。
S1102，当第一CG传输时机对应的数据传输出错时，接入网设备向终端发送第一重传指示信息，该第一重传指示信息用于指示第一CG传输时机对应的数据出错，或者用于指示终端重传第一CG传输时机对应的数据。
可选的，第一重传指示信息中包括第一CG传输时机对应的重传资源的调度信息。示例性地，在重传资源可以是HARQ进程的情况下，第一重传指示信息可以包括第一CG传输时机对应的HARQ process ID。例如，接入网设备可以在DCI中的HARQ process ID指示域中添加前述第一重传指示信息。
S1103，终端在第一重传指示信息指示的重传资源上，重传对应的CG传输时机的上行信息。
例如，第一重传指示信息为中第一CG传输时机对应的HARQ process ID，那么终端可以在该HARQ process ID所指示的HRAQ进程上重传上行信息。
