可选地，该方法还包括：基于CG信息获得CG周期的时长。
通过该方法，便于在CG周期内可以完成一个XR视频帧的完整传输，从而提升用户对XR业务的接收体验。
结合第一方面，在第一方面的某些实施方式中，CG信息包括TB配置数量信息。基于CG信息获得CG周期内TB的配置数量N，包括：基于TB配置数量信息获得TB的配置数量N。
通过上述的CG信息实现方式，可以借助CG信息中专门的字段或信元配置CG周期中 最多可传输TB的数量，由于该专门的字段或信元可以为了实现CG周期中最多可传输TB数量的配置而专门设计其取值范围，因此可以使得CG周期中最多可传输TB的数量配置更有针对性。
结合第一方面，在第一方面的某些实施方式中，CG信息包括重复传输配置信息和重复传输次数信息。基于CG信息获得CG周期内TB的配置数量N，包括：基于重复传输配置信息和重复传输次数信息获得TB的配置数量N。这一实现方式可以理解为复用CG信息中的重复传输次数信息，来进行CG周期中最多可传输TB的数量的配置。上述重复传输配置信息可理解为用来配置重复传输次数信息的功能。当重复传输配置信息被配置为某一预设值时，重复传输次数信息用来配置CG周期中最多可传输TB的数量。当重复传输配置信息被配置为另一预设值时，复传输次数信息用来配置CG周期中的重复传输次数。

结合第一方面，在第一方面的某些实施方式中，在第一时间单元向网络设备发送MAC CE，包括：当待传输数据量大于第二阈值时，在第一时间单元向网络设备发送MAC CE。待传输 数据量可以是CG对应的逻辑信道所对应的待传输数据量。该CG可以是由前述CG信息所配置的CG。通过该实施方式，当配置的N个TB无法承载待传数据量，说明此时配置的资源不足，此时通过MAC CE通知网络设备，网络设备可以根据该MAC CE，分配额外的传输资源，以便及时传输剩余数据，以降低传输时延。
结合第一方面，在第一方面的某些实施方式中，在第一时间单元向网络设备发送MAC CE，包括：
当接收到预设参数或预设参数被配置为预设值时，或者
当第二时间单元与第一时间单元之间的间隔大于第一阈值时，并且当接收到预设参数或预设参数被配置为预设值时，或者
当待传输数据量大于第二阈值时，并且当接收到预设参数或预设参数被配置为预设值时：
在第一时间单元向网络设备发送MAC CE。
在上述MAC CE基于LCH向网络设备上报M或缓存大小中的至少一个的情况下，上述预设参数例如可以表示为enhanced-per-LCH-BSR。在一种可能的实现方法中，当接收到该enhanced-per-LCH-BSR，则在第一时间单元向网络设备发送MAC CE。在另一种可能的实现方法中，当该enhanced-per-LCH-BSR被设置为预设值时，则在第一时间单元向网络设备发送MAC CE，前述预设值例如可以是“true”、“enable”、“0”或“1”等。
在上述MAC CE基于LCG向网络设备上报M或缓存大小中的至少一个的情况下，上述预设参数例如可以表示为enhanced-cg-BSR。在一种可能的实现方法中，当接收到该enhanced-cg-BSR，则在第一时间单元向网络设备发送MAC CE。在另一种可能的实现方法中，当该enhanced-cg-BSR被设置为预设值时，则在第一时间单元向网络设备发送MAC CE，前述预设值例如可以是“true”、“enable”、“0”或“1”等。
通过上述实施方式，终端设备可以根据一定的条件判断是否有必要向网络设备发送上述MAC CE，避免了无效的信令指示和资源浪费。
结合第一方面，在第一方面的某些实施方式中，第一阈值为预定义的，或者是由网络设备配置的。
在第一阈值为预定义的情况下，第一阈值可以是由协议预先规定的值。
在第一阈值由网络设备配置的情况下，网络设备可以通过RRC消息中的信元配置第一阈值。用于配置第一阈值的RRC消息中的信元可以是新定义的信元，也可以复用已有的信元。例如，可以复用cg-minDFI-Delay信元配置第一阈值，cg-minDFI-Delay表示从PUSCH的结束符号到包含承载该PUSCH对应的HARQ-ACK的下行反馈指示(downlink feedback indicator，DFI)的PDCCH的起始符号的最小时间间隔。第一阈值还可以由两个或两个以上的信元/参数共同确定。例如，第一阈值可以通过cg-minDFI-Delay信元配置的值C1以及K2的值共同确定，其中K2表示终端收到承载于下行控制信息(downlink control information，DCI)下行调度信息到在该下行调度信息调度的PUSCH发送上行数据的最小时间间隔。比如第一阈值可以表示为C1+K2。K2的值可以由下行调度信息指示(例如可以由下行调度信息中的“minimum applicable scheduling offset indicator”域指示)，也可以由网络设备通过RRC消息中的信元配置(例如可以由minimumSchedulingOffsetK2信元配置)。
通过上述实施方式，终端设备可以获知网络设备的处理时延，当网络设备处理时延太大而导致CG周期内剩余的资源无法用于调度其他终端时，终端设备不必发送上述UCI或MAC CE，从而节省信令开销。
结合第一方面，在第一方面的某些实施方式中，第二阈值为前述配置的N个TB能承载 的总数据量。通过该实施方式，当配置的N个TB无法承载待传数据量，说明此时配置的资源不足，此时通过上述UCI或MAC CE通知网络设备，网络设备可以根据UCI或MAC CE，分配额外的传输资源，以便及时传输剩余数据，以降低传输时延。
通过上述实施方式，网络设备可以获知终端在CG周期内实际传输的TB数量，使得网络设备可以将CG周期中没有被该终端占用的CG资源调度给其他终端使用，从而避免资源的浪费，提高资源利用率。此外，通过上述实施方式，对于未被终端占用的CG资源，网络设备也不会误认为终端在该CG资源上传输失败，从而无需再向终端发送调度信息指示数据重传，避免了不必要的信令开销。
第二方面，本申请实施例提供一种通信方法，该方法可以由网络设备执行，也可以由网络设备的部件(例如处理器、芯片、或芯片系统等)执行，还可以由能实现全部或部分网络设备功能的逻辑模块或软件实现。该方法包括：向终端发送CG信息，CG信息用于配置CG周期内TB的配置数量N，TB的配置数量N为CG周期中最多可传输的TB的数量，N为大于0的整数。以及在CG周期中接收来自所述终端的与M个TB对应的上行数据，其中，M为大于0且小于等于N的整数。

可选地，当重复传输配置信息被配置为预设值时，重复传输次数信息用于N的配置。
结合第二方面，在第二方面的某些实施方式中，该方法还包括：接收来自终端的UCI，并基于该UCI获得M。该方法可以理解为通过UCI向网络设备指示在CG周期中向网络设备实际发送的TB数量M。可选地，该UCI为CG-UCI，CG-UCI用于向网络设备发送与CG有关的控制信息。可选地，该UCI可以由PUSCH承载，也可以由PUCCH承载。
可选地，上述UCI包括TB激活信息。基于UCI获得M，包括：基于该TB激活信息获得M。可选地，TB激活信息为TB激活数量信息或TB激活位图信息。进一步可选地，UCI还包括HARQ信息、RV信息、NDI信息或COT共享信息中的一种或多种。
结合第二方面，在第二方面的某些实施方式中，接收来自终端的UCI，包括：在第一时间单元接收来自终端的UCI，第一时间单元为所述配置的N个TB中第一个TB对应的时间单元。第一时间单元可以是一个或多个时隙，也可以是一个或多个时域符号。上述第一个TB对应的时间单元可以有不同的理解。例如，第一个TB对应的时间单元可以理解成CG周期内配置的N个TB中的第一个TB对应的时隙或时域符号，或者也可以理解成CG周期内配置的N个TB中在数据到达后的第一个TB对应的时隙或时域符号。通过该实施方式，网络设备可以尽早通过UCI获知CG周期中实际发送的TB数量M，以便根据实际的TB数量将未用的资源分配给其他终端使用，避免资源浪费。
结合第二方面，在第二方面的某些实施方式中，该方法还包括：接收来自终端的MAC CE，并基于MAC CE获得M或缓存大小中的至少一个。
可以理解，在获得缓存大小的情况下，网络设备也可以进一步获得M。网络设备知道CG周期内配置的N个TB中每个TB所能承载的数据量，结合缓存大小(也可理解为待传数据量)，由此可以确定CG周期内该终端实际传输需要的TB数量M。
通过上述实施方式，网络设备可以通过MAC CE的方式获知M或缓存大小中的至少一个，以便将未用的资源分配给其他终端使用，避免资源浪费。
结合第二方面，在第二方面的某些实施方式中，接收来自终端的MAC CE，包括：在第一时间单元接收来自终端的MAC CE，第一时间单元为前述配置的N个TB中第一个TB对应的时间单元。第一时间单元可以是一个或多个时隙，也可以是一个或多个时域符号。上述第一个TB对应的时间单元可以有不同的理解。例如，第一个TB对应的时间单元可以理解成CG周期内配置的N个TB中的第一个TB对应的时隙或时域符号，或者也可以理解成CG周期内配置的N个TB中在数据到达后的第一个TB对应的时隙或时域符号。通过该实施方式，网络设备可以尽早通过MAC CE获知CG周期中实际发送的TB数量M或缓存大小中的至少一个，以便将未用的资源分配给其他终端使用，避免资源浪费。

XR技术具有多视角、交互性强等优点，能够为用户提供一种全新的体验，具有极大的应用价值和商业潜力。XR包含VR、AR和MR等技术，能够广泛应用于娱乐、游戏、医疗、 广告、工业、在线教育、以及工程等诸多领域。VR技术主要是指对视觉和音频场景的渲染以尽可能地模拟现实世界中的视觉和音频对用户的感官刺激，VR技术中通常用户会佩戴XR终端(例如头戴式设备)进而向用户模拟视觉和/或听觉。VR技术还可以对用户进行动作跟踪，从而及时更新模拟的视觉和/或听觉内容。AR技术主要是指在用户感知的现实环境中提供视觉和/或听觉的附加信息或人工生成内容，其中，用户对现实环境的获取可以是直接的(例如不进行感测、处理和渲染)，也可以是间接的(例如通过传感器等方式进行传递)，并进行进一步的增强处理。MR技术是将一些虚拟元素插入到物理场景中，目的是为用户提供一种这些元素是真实场景一部分的沉浸体验。
XR的数据量一般较大，并且具有动态变化的特点，因此如何能够合理的利用有限的无线资源高效传输XR数据是一个亟待解决的问题。
本申请中提供了一种数据传输方法，在该方法中通过对配置授权(configured grant，CG)周期中最多可传输的传输块(transport block，TB)进行配置，能够适配XR数据的特点，从而利用有限的资源完成高效的数据传输。可以理解，本申请提供的方法并不限制其应用的数据业务类型，XR数据之外的数据业务类型也同样适用。
本申请提供的实施例适用于多种不同的场景。图2-图5示出了本申请实施例适用的几种系统框架示意图。
图2示出了一种本申请实施例适用的场景示意图。图2示意了一个系统200，包含服务器210、核心网和接入网220(可简称为传输网络220，例如LTE、5G或6G网络)、以及终端230。其中，服务器210可用于对XR的源数据进行编解码和渲染，传输网络220可用于对XR数据的传输，终端230通过对XR数据的处理为用户提供多样化的XR体验。可以理解，传输网络220与终端230之间还可以包含其他的装置，例如还可以包含其他的终端(例如手机、笔记本电脑、或车载终端等)和/或网络设备(例如中继设备、一体化接入回传(integrated access backhaul，IAB)设备、WiFi路由器、或WiFi接入点等)，终端230借助其他的终端和/或网络设备从传输网络220获得XR数据。
图3示出了另一种本申请实施例适用的场景示意图。图3示意了一个系统300，包含终端320和其他终端310。其他终端310是终端320之外的终端。其他终端310可以向终端320传输XR数据。例如，其他终端310可将XR数据投屏至终端320。又例如，其他终端310和终端320为车载终端，车载终端之间可进行XR数据的交互。可以理解，其他终端310还可以与传输网络(例如LTE、5G或6G网络)相连，以获得来自传输网络的XR数据，或者向传输网络发送数据。
图4示出了另一种本申请实施例适用的场景示意图。图4示意了一个系统400，包含终端430、WiFi路由器或WiFi接入点420(可简称为WiFi装置420)、和其他终端410。其他终端410是终端430以外的终端。其他终端410可借助WiFi装置420向终端430传输XR数据。例如，其他终端410是手机设备，WiFi装置420是WiFi路由器、WiFi接入点或机顶盒，终端430是电视设备、智慧屏设备或电子平板设备，手机设备可通过WiFi路由器、WiFi接入点或机顶盒将XR数据投屏至电视设备、智慧屏设备或电子平板设备上呈现给用户。
图5示出了另一种本申请实施例适用的场景示意图。图5示意了一个系统500，包含服务器510、固网520、WiFi路由器或WiFi接入点530(可简称为WiFi装置530)、和终端540。服务器510可用于对XR的源数据进行编解码和渲染，并借助固网520和WiFi装置530向终端540传输XR数据。例如，固网520为运营商网络，WiFi装置530是WiFi路由器、WiFi接入点或机顶盒，服务器510借助运营商网络520和WiFi装置530将XR数据传输或投屏到 终端540。
可以理解，图2-图5仅给出了本申请实施例可以适用的几种场景示意，并没有对本申请实施例的适用场景产生限定。
下面结合附图对本申请的技术方案进行说明。
另外为便于理解本申请的技术方案，首先对XR或者视频业务的特点以及CG机制进行简要介绍。
对于XR或者视频业务数据，其通常具有一定的帧率和周期性。以图6为例，给出了帧率为60帧每秒(frame per second，FPS)的情况下，XR业务的画面帧在时间上的分布示意图。从图6中可以看出，在60FPS的情况下，每隔1000/60≈16.67ms会出现或到达一个画面帧。
其他可能的帧率还包括30FPS、90FPS以及120FPS。无线接入网设备可以通过多种不同的方式获得XR或视频业务数据的帧率。
例如，无线接入网设备可以通过与数据对应的服务质量(quality of service，QoS)流的配置信息，例如QoS模板(QoS profile)，获得XR或视频业务数据的帧率。又例如，无线接入网设备可以通过检测QoS流中数据包的到达时间间隔来获得XR或视频业务数据的帧率。又例如，终端可以通过辅助信息，例如信元UEAssistanceInformation，将上行数据的帧率或者是与帧率有关的信息上报给无线接入网设备。
终端也可以通过多种不同的方式获得XR或视频业务数据的帧率。
例如，终端可以通过与数据对应的QoS流的配置信息，例如QoS规则(QoS rule)，获得XR或视频业务数据的帧率。又例如，终端可以通过检测QoS流中数据包的到达时间间隔来获得XR或视频业务数据的帧率。又例如，终端可以通过协议层间的交互，将应用层数据的帧率或者是与帧率有关的信息通知给终端的应用层以下的协议层(例如RRC层)。
配置授权(configured grant，CG)机制是一种适合于进行上行周期性业务传输的数据传输机制。通过CG机制，可以在上传数据传输过程中，借助RRC消息或下行控制信息(downlink control information，DCI)为终端分配用于上行数据传输的资源(也可以称为CG资源)，使得终端可以周期性地重复使用该分配的资源进行上行数据传输。CG机制有时也可以被称为配置调度(configured scheduling，CS)机制或免授权(grant free，GF)机制。
CG机制包括两种类型：CG类型1和CG类型2。下面分别介绍这两种CG类型的工作流程。
●CG类型1：
在CG类型1中，无线接入网设备通过RRC消息为终端提供相关的CG配置，例如CG周期、CG资源等。该RRC消息还用于激活CG配置，终端在收到该RRC消息后，可以基于该RRC消息配置的CG周期和CG资源向无线接入网设备发送上行数据。
在CG类型1中，无线接入网设备通过向终端发送DCI，指示终端去激活CG配置。终端在接收到该DCI后，可以释放CG资源，或者也可以理解为停止/暂停在该CG资源上的上行数据发送。
●CG类型2：
在CG类型2中，无线接入网设备通过RRC消息为终端提供相关的CG配置，例如CG周期等。无线接入网设备进一步通过DCI向终端指示CG资源。终端在收到该DCI后，可以基于RRC消息配置的CG周期和DCI指示的CG资源向无线接入网设备发送上行数据。上述DCI也可以理解为在指示并激活了CG资源。
在CG类型2中，无线接入网设备通过向终端发送另一个DCI，指示终端去激活CG配置。终端在接收到该DCI后，可以释放CG资源，或者也可以理解为停止/暂停在该CG资源上的上行数据发送。
在上述CG机制(包括CG类型1和CG类型2)中，一般在一个CG周期中会配置一个CG资源，用于传输一个传输块(transport block，TB)。对于可靠性要求较高的业务，比如超可靠低时延通信(ultra-reliable low-latency communication，URLLC)的业务，可以在一个CG周期中配置多个CG资源，用于传输一个TB的不同冗余版本(redundancy version，RV)，从而提升数据传输的可靠性。其中，RV的设计用于实现增量冗余(incremental redundancy，IR)混合自动重传请求(hybrid automatic repeat request，HARQ)传输。比如，将编码生成的比特分成若干比特组，每个RV对应一个比特组，初传和重传分别使用不同RV对应的比特组，以实现冗余比特的逐步积累，完成IR HARQ操作，达到提升数据传输可靠性的效果。
上述传输一个TB的不同RV，也可以被称为对该TB的重复传输，或者是被称为CG重复传输、物理上行共享信道(physical uplink shared channel，PUSCH)重复传输。无线接入网设备可以通过RRC消息中的重复传输次数信息为终端配置CG周期中的重复传输次数。
CG机制中的PUSCH重复传输有两种类型：PUSCH重复类型A和PUSCH重复类型B。下面分别介绍这两种PUSCH重复类型。
●PUSCH重复类型A：
PUSCH重复类型A可以理解为时隙(slot)级别的重复传输，即在多个连续或不连续的时隙中传输一个TB的不同RV，每个时隙中的CG资源配置是相同的。
●PUSCH重复类型B：
PUSCH重复类型B可以理解为微时隙(mini-slot)级别的重复传输，即在多个连续或不连续的微时隙中传输一个TB的不同RV，每个微时隙中的CG资源配置是相同的。例如，当一个时隙包含14个符号时，一个微时隙包含2个符号或7个符号。此外，微时隙级别的重复传输可以在一个时隙内，也可以跨越多个时隙。
如前所述，对于XR或者视频业务数据，其通常具有一定的帧率和周期性，因此CG机制也适合于传输这种具有周期性的XR或者视频业务数据。但是，由于XR或者视频业务数据的数据量一般较大，并且具有动态变化的特点，因此如何能够合理的利用有限的无线资源高效传输XR或者视频业务数据是一个亟待解决的问题。
本申请中提供了一种CG配置方法，可以通过配置CG周期内传输多个TB，使得CG机制能更好地适配XR或视频业务数据的传输。可以理解，本申请提供的方法并不限制其应用的数据业务类型，XR和或者视频业务数据之外的数据业务类型也同样适用。
图7为本申请实施例提供的一种CG配置方法700的交互示意图。图7中以无线接入网设备和终端作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图7中的无线接入网设备也可以是支持该无线接入网设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分无线接入网设备功能的逻辑模块或软件；图7中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端功能的逻辑模块或软件。如图7所示，该实施例的方法700可包括710部分、720部分和730部分。
710部分：无线接入网设备向终端发送CG信息，该CG信息用于配置CG周期内TB的配置数量N，该TB的配置数量N为CG周期中最多可传输的TB的数量，N为大于0的整数。相应地，终端接收来自无线接入网设备的CG信息。
本申请中的TB也可以理解为承载TB的PUSCH、PUSCH传输机会、时隙或时域符号。本申请中的TB数量也可以理解为承载TB的PUSCH数量、PUSCH传输机会数量、时隙数量或时域符号数量。
可选地，该CG信息由RRC消息承载。例如，该CG信息可以是RRC消息中的ConfiguredGrantConfig信元。可以理解，ConfiguredGrantConfig仅是CG信息的一种可能性名称，本申请对CG信息的名称不作限定。
720部分：终端基于上述CG信息获得CG周期内TB的配置数量N。
730部分：终端在CG周期中向无线接入网设备发送与M个TB对应的上行数据，其中，M为大于0且小于等于N的整数。相应地，无线接入网设备在CG周期中接收来自终端的与M个TB对应的上行数据。
XR的视频帧一般较大，通过方法700可以在一个CG周期内传输更多的TB，从而便于在CG周期内可以完成一个XR视频帧的完整传输，从而提升用户对XR业务的接收体验。
方法700中，CG信息还可用于配置CG周期的时长。相应地在720部分中，终端还可以基于CG信息获得CG周期的时长。
方法700中，无线接入网设备向终端发送CG信息，为终端配置CG周期内最多可传输的TB数量N。可以通过不同的实施方式进行N的配置。
在一种可能的CG信息的实现方式中，该CG信息包括TB配置数量信息，该TB配置数量信息用于配置TB的配置数量N。相应地，在720部分中，终端基于TB配置数量信息，获得TB的配置数量N。
例如，CG信息为RRC消息中的ConfiguredGrantConfig信元，ConfiguredGrantConfig信元中包括cg-maxNrofTB信元。该cg-maxNrofTB信元为上述TB配置数量信息，用于配置TB的配置数量N。终端基于cg-maxNrofTB信元，获得TB的配置数量N。例如，ConfiguredGrantConfig和cg-maxNrofTB信元可以如下表所示：
表1
Figure PCTCN2022113653-appb-000001
上表中以cg-maxNrofTB信元表示的取值为1,2…,8为例进行示意，其表示上述TB的配置数量N的可能取值为1,2…,8，即表示CG周期中最多可传输的TB的数量为1,2…,8。可以理解，上表仅是以cg-maxNrofTB信元表示的取值为1,2…,8进行示例，不排除可以有其他的取值。此外，上述cg-maxNrofTB仅是TB配置数量信息的一种可能的信元名称，本申请对TB配置数量信息的信元名称不作限定。可以理解，ConfiguredGrantConfig信元中还可以有其他的用于配置CG的信元。
通过上述的CG信息实现方式，可以借助CG信息中专门的字段或信元配置CG周期中最多可传输TB的数量，由于该专门的字段或信元可以为了实现CG周期中最多可传输TB数量的配置而专门设计其取值范围，因此可以使得CG周期中最多可传输TB的数量配置更有针对性。
在另一种可能的CG信息的实现方式中，该CG信息包括重复传输配置信息和重复传输次数信息，该重复传输配置信息和该重复传输次数信息用于配置TB的配置数量N。相应地，在720部分中，终端基于该重复传输配置信息和该重复传输次数信息，获得TB的配置数量N。这一实现方式可以理解为复用CG信息中的重复传输次数信息，来进行CG周期中最多可传输TB的数量的配置。上述重复传输配置信息可理解为用来配置重复传输次数信息的功能。 当重复传输配置信息被配置为某一预设值时，重复传输次数信息用来配置CG周期中最多可传输TB的数量。当重复传输配置信息被配置为另一预设值时，复传输次数信息用来配置CG周期中的重复传输次数。
可选地，当重复传输配置信息被配置为预设值A1时，重复传输次数信息用于配置CG周期中最多可传输TB的数量N，相应地，终端基于该重复传输次数信息获得N。或者也可以理解为，当重复传输配置信息被配置为预设值A1时，重复传输次数信息用于配置CG周期中的非重复传输。
可选地，当重复传输配置信息被配置为预设值A2时，重复传输次数信息用于配置CG周期中的重复传输次数。或者也可以理解为，当重复传输配置信息被配置为预设值A2时，重复传输次数信息用于配置CG周期中的重复传输。
例如，CG信息为RRC消息中的ConfiguredGrantConfig信元，ConfiguredGrantConfig信元中包括cg-repIndicator信元和repK信元。cg-repIndicator信元为上述重复传输配置信息，repK信元为上述重复传输次数信息。例如，ConfiguredGrantConfig、cg-maxNrofTB和repK信元可以如下表所示：
表2
Figure PCTCN2022113653-appb-000002
上表中以cg-repIndicator信元表示的取值为枚举值true或false为例，cg-repIndicator信元表示的取值也可以是布尔值true或false(例如表示成“cg-repIndicator BOOL{true,false}”)。
比如，“true”可以作为上述预设值A1，“false”可以作为上述预设值A2。当cg-repIndicator信元被配置为true时，repK信元用于配置CG周期中最多可传输TB的数量N；当cg-repIndicator信元被配置为false时，repK信元用于配置CG周期中的重复传输次数。
又比如，“false”可以作为上述预设值A1，“true”可以作为上述预设值A2。当cg-repIndicator信元被配置为false时，repK信元用于配置CG周期中最多可传输TB的数量N；当cg-repIndicator信元被配置为true时，repK信元用于配置CG周期中的重复传输次数。
上表中以repK信元表示的取值为枚举值n1,n2,n4,n8为例进行示意。其中，当repK信元用于配置CG周期中最多可传输TB的数量N时，n1表示CG周期中最多可传输TB的数量N为1，n2表示CG周期中最多可传输TB的数量N为2，n4表示CG周期中最多可传输TB的数量N为4，n8表示CG周期中最多可传输TB的数量N为8；当repK信元用于配置CG周期中的重复传输次数时，n1表示CG周期中的重复传输次数为1，n2表示CG周期中的重复传输次数为2，n4表示CG周期中的重复传输次数为4，n8表示CG周期中的重复传输次数为8。
可以理解，上表仅是以cg-repIndicator信元表示的取值为true或false、repK信元表示的取值为n1,n2,n4,n8进行示例，不排除可以有其他的取值。此外，上述cg-repIndicator和repK仅是重复传输配置信息和重复传输次数信息的可能的信元名称，本申请对重复传输配置信息和重复传输次数信息的信元名称不作限定。可以理解，ConfiguredGrantConfig信元中还可以有其他的用于配置CG的信元。
通过上述的CG信息实现方式，可以复用CG信息中的重复传输次数信息进行CG周期中最多可传输TB的数量的配置，从而可以减少配置信息的开销。
在重配置或更新CG的配置信息前，CG资源的大小一般是不变的。然而，XR或视频业 务数据具有动态变化的特点，大小固定不变的CG资源有可能无法匹配XR或视频业务数据的这一特点。如果配置的CG资源充足，虽然可以满足XR或视频业务数据的传输需求，但会造成资源的浪费，降低资源利用率。如果配置的CG资源不足，虽然可以提高资源利用率，但是可能会造成数据传输时延的增加，从而无法满足XR或视频业务数据的传输需求。
以图8为例，示意了帧率为60FPS的XR业务的画面帧在时间上的分布，每隔1000/60≈16.67ms会出现或到达一个画面帧，不同时间上的画面帧的帧大小不同。时刻t1的画面帧的帧大小最大，时刻t2的画面帧的帧大小最小，时刻t2的画面帧的帧大小居中。以CG资源根据最大画面帧的帧大小进行配置，如图8所示，配置的CG资源在CG周期中最多可传输的TB数量N为4。那么除了时刻t1的画面帧数据可以占用CG周期内的全部CG资源以外，时刻t2和t3的画面帧数据都没有完全占用对应CG周期内的全部CG资源，图中分别用不同的阴影表示不同时刻的画面帧数据占用CG资源的情况。由此可以看出，当配置的CG资源充足时，虽然可以满足XR或视频业务数据的传输需求，但会造成资源的浪费，降低资源利用率。
此外，无线接入网设备对于图8中没有承载数据的CG资源，可能会误认为终端在该资源上进行了传输，但是传输失败。在这种情况下，无线接入网设备会通过调度信息指示终端进行数据重传，这样会造成不必要的信令开销，并且终端还需要监听调度信息，从而增加了终端的功耗。
以图9为例，同样示意了与图8相同的XR业务的画面帧在时间上的分布以及帧大小。如图9所示，配置的CG资源在CG周期中最多可传输的TB数量N为3，则图9中示意的CG周期中的CG资源不足以完整传输时刻t1的画面帧数据，因此时刻t1的画面帧数据的一部分被延迟至下一个CG周期中进行传输，从而导致时延的增加，造成用户的体验下降。
为了解决上述问题，可选地，方法700还可以包括：终端向无线接入网设备发送上行控制信息(uplink control information，UCI)，该UCI用于指示前述M，即该UCI用于向无线接入网设备指示终端在CG周期中向无线接入网设备实际发送的TB数量。相应地，无线接入网设备接收来自终端的UCI，并基于该UCI获得前述M。可选地，该UCI为配置授权UCI(CG-UCI)，CG-UCI用于终端向无线接入网设备发送与CG有关的控制信息。可选地，该UCI可以由PUSCH承载，也可以由物理上行控制信道(physical uplink control channel，PUCCH)承载。
通过上述方法，无线接入网设备可以获知终端在CG周期内实际传输的TB数量，使得无线接入网设备可以将CG周期中没有被该终端占用的CG资源调度给其他终端使用，从而避免资源的浪费，提高资源利用率。此外，通过上述方法，对于未被终端占用的CG资源，无线接入网设备也不会误认为终端在该CG资源上传输失败，从而无需再向终端发送调度信息指示数据重传，避免了不必要的信令开销。
在上述UCI的一种可能的实现方式中，该UCI包括TB激活信息，该TB激活信息用于向无线接入网设备指示终端在CG周期内实际传输的TB数量M。相应地，无线接入网设备基于该TB激活信息获得M。可选地，该UCI中还可以包括下述信息中的一种或多种：HARQ信息、RV信息、新数据指示符(new data inficator，NDI)信息或信道占用时间(channel occupancy time，COT)共享信息。其中，HARQ信息指示上行数据传输对应的HARQ进程号，RV信息指示上行数据传输对应的RV，NDI信息指示上行数据传输是否为新数据，COT共享信息指示非授权频段通信场景下的信道占用时间信息。
在TB激活信息的一种可能的实现方式中，该TB激活信息为TB激活数量信息，该TB 激活数量信息用于向无线接入网设备指示终端在CG周期内实际传输的TB数量M。相应地，无线接入网设备基于该TB激活数量信息获得M。
可选地，上述UCI中包括cg-ActiveTB字段，该cg-ActiveTB字段承载的信息为上述TB激活数量信息。该cg-ActiveTB字段的比特位数可以与N的可能的取值数量有关。例如，当N的可能取值为{1,2,…,8}时(共8个可能取值)，cg-ActiveTB字段的比特位数可以是log 2(8)＝3。当N的可能取值为{1,2,…,16}时(共16个可能取值)，cg-ActiveTB字段的比特位数可以是log 2(16)＝4。当N的可能取值为{1,2,4,8}时(共4个可能取值)，cg-ActiveTB字段的比特位数可以是log 2(4)＝2。可以理解cg-ActiveTB仅是TB激活数量信息的可能字段名称，本申请对TB激活数量信息的字段名称不作限定。
在TB激活信息的另一种可能的实现方式中，该TB激活信息为TB激活位图(bitmap)信息，该TB激活位图信息用于向无线接入网设备指示终端在CG周期内实际传输的TB数量M。相应地，无线接入网设备基于该TB激活位图信息获得M。
可选地，上述UCI中包括cg-ActiveTBBitmap字段，该cg-ActiveTBBitmap字段承载的信息为上述TB激活位图信息。该cg-ActiveTBBitmap字段的比特位数可以与N的可能的取值数量有关。例如，当N的可能取值为{1,2,…,8}时(共8个可能取值)，cg-ActiveTBBitmap字段的比特位数可以是8。当N的可能取值为{1,2,…,16}时(共16个可能取值)，cg-ActiveTBBitmap字段的比特位数可以是16。当N的可能取值为{1,2,4,8}时(共4个可能取值)，cg-ActiveTBBitmap字段的比特位数可以是4。M的取值等于cg-ActiveTBBitmap字段中“1”的比特数量，或者，M的取值等于cg-ActiveTBBitmap字段中“0”的比特数量。可以理解cg-ActiveTBBitmap仅是TB激活位图信息的可能字段名称，本申请对TB激活位图信息的字段名称不作限定。
以图10为例对上述TB激活信息的一种传输方式进行描述。图10中，示意了帧率为60FPS的XR业务的画面帧在时间上的分布，每隔16.67ms会出现或到达一个画面帧，不同时间上的画面帧的帧大小不同。时刻t1的画面帧的帧大小最大，时刻t2的画面帧的帧大小最小，时刻t2的画面帧的帧大小居中。以CG资源根据最大画面帧的帧大小进行配置，那么除了时刻t1的画面帧数据可以占用CG周期内的全部CG资源以外，时刻t2和t3的画面帧数据都没有完全占用对应CG周期内的全部CG资源，图中分别用不同的阴影表示不同时刻的画面帧数据占用CG资源的情况以及TB激活信息。
为了能够让无线接入网设备获知终端在CG周期内实际传输的TB数量M，终端在每个CG周期(图中示意的CG周期时长为16.67ms)中向无线接入网发送上行数据时，也向无线接入网设备发送上述TB激活信息。在第一个CG周期中，TB激活信息指示在该CG周期内实际传输的TB数量M为4。在第二个CG周期中，TB激活信息指示在该CG周期内实际传输的TB数量M为2。在第三个CG周期中，TB激活信息指示在该CG周期内实际传输的TB数量M为3。
以图11为例对上述TB激活信息的另一种传输方式进行描述。图11同样示意了与图10相同的XR业务的画面帧在时间上的分布以及帧大小。与图10示意的传输方式不同的地方在于，在图11示意的传输方式中，当在CG周期内实际传输的TB数量M等于CG周期中最多可传输的TB数量N时，终端不发送上述TB激活信息。无线接入网设备在没有收到上述TB激活信息时，可以获知M＝N。
可以理解，图10和图11中的TB激活信息占用的资源位置仅用作示意，TB激活信息也可以占用其他的资源位置，本申请对此不作限定。
在终端向无线接入网设备发送上述UCI的一种可能的实施方式中，终端在第一时间单元向无线接入网设备发送上述用于指示M的UCI。第一时间单元可以是一个或多个时隙，也可以是一个或多个时域符号。上述第一个TB对应的时间单元可以有不同的理解。例如，第一个TB对应的时间单元可以理解成CG周期内配置的N个TB中的第一个TB对应的时隙或时域符号，或者也可以理解成CG周期内配置的N个TB中在数据到达后的第一个TB对应的时隙或时域符号。通过该实施方式，网络设备可以通过UCI尽早获知CG周期中实际发送的TB数量M，以便将未用的时隙资源分配给其他终端使用，避免资源浪费。
终端可以在满足一定条件的情况下，在第一时间单元向无线接入网设备发送上述用于指示M的UCI。
在一种可能的实施方式中，在满足下述条件1时，终端在第一时间单元向无线接入网设备发送上述UCI。
条件1：第二时间单元与第一时间单元之间的间隔大于第一阈值。
其中，第二时间单元为前述配置的N个TB中第N个TB对应的时间单元。第二时间单元可以是一个或多个时隙，也可以是一个或多个时域符号。上述第N个TB对应的时间单元可以理解成CG周期内配置的N个TB中的第N个TB(即最后一个TB)对应的时隙或时域符号。
第一阈值为预定义的，或者是由无线接入网设备配置的。
在第一阈值为预定义的情况下，第一阈值可以是由协议预先规定的值。
在第一阈值由无线接入网设备配置的情况下，无线接入网设备可以通过RRC消息中的信元配置第一阈值。用于配置第一阈值的RRC消息中的信元可以是新定义的信元，也可以复用已有的信元。例如，可以复用cg-minDFI-Delay信元配置第一阈值，cg-minDFI-Delay表示从PUSCH的结束符号到包含承载该PUSCH对应的HARQ-ACK的下行反馈指示(downlink feedback indicator，DFI)的PDCCH的起始符号的最小时间间隔。第一阈值还可以由两个或两个以上的信元/参数共同确定。例如，第一阈值可以通过cg-minDFI-Delay信元配置的值C1以及K2的值共同确定，其中K2表示终端收到承载于下行控制信息(downlink control information，DCI)下行调度信息到在该下行调度信息调度的PUSCH发送上行数据的最小时间间隔。比如第一阈值可以表示为C1+K2。K2的值可以由下行调度信息指示(例如可以由下行调度信息中的“minimum applicable scheduling offset indicator”域指示)，也可以由无线接入网设备通过RRC消息中的信元配置(例如可以由minimumSchedulingOffsetK2信元配置)。
通过上述实施方式，终端设备可以获知网络设备的处理时延，当网络设备处理时延太大而导致CG周期内剩余的资源无法用于调度其他终端时，终端设备不必发送上述UCI，从而节省信令开销。
在另一种可能的实施方式中，在满足下述条件2时，终端在第一时间单元向无线接入网设备发送上述UCI。
条件2：待传输数据量大于第二阈值。
待传输数据量可以是CG对应的逻辑信道所对应的待传输数据量。该CG可以是由前述CG信息所配置的CG。第二阈值可以为前述配置的N个TB能承载的总数据量。
通过上述实施方式，当配置的N个TB无法承载待传输数据量，说明此时配置的资源不足，此时通过UCI通知网络设备，网络设备可以根据上述UCI，分配额外的传输资源，以便及时传输剩余数据，以降低传输时延。
为了解决图8或图9示意的问题，可选地，方法700还可以包括：终端向无线接入网设 备发送媒体接入控制(media access control，MAC)控制元素(control element，CE)，该MAC CE用于指示前述M或缓存大小(buffer size)中的至少一个。该MAC CE可以用于基于逻辑信道(logical channel，LCH)或逻辑信道组(logical channel group，LCG)向无线接入网设备上报M或缓存大小中的至少一个，其中一个LCG包括一个或多个LCH。缓存大小也可以理解为终端的待传数据量。
在上述MAC CE基于LCH向无线接入网设备上报M或缓存大小中的至少一个的情况下，该MAC CE中包括LCH的标识符，还包括指示M或缓存大小中至少一项的信息。LCH的标识符例如可以是LCH ID，指示M的信息例如可以由cg-ActiveTB字段承载，指示缓存大小的信息例如可以由Buffer Size字段承载。通过该实施方式，网络设备可以知道具体某个LCH对应的实际发送的TB数量M或缓存大小中至少一项的信息，以便网络设备可以进行更加精细的调度(例如LCH粒度的调度)，提高资源利用率。
在上述MAC CE基于LCG向无线接入网设备上报M或缓存大小中的至少一个的情况下，该MAC CE中包括LCG的标识符，还包括指示M或缓存大小中至少一项的信息。LCG的标识符例如可以是LCG ID，指示M的信息例如可以由cg-ActiveTB字段承载，指示缓存大小的信息例如可以由Buffer Size字段承载。在MAC CE指示缓存大小的情况下，无线接入网设备可以知道终端的待传输数据量，由于无线接入网设备也知道CG周期内为终端配置的N个TB中每个TB所能承载的数据量，因此无线接入网设备可以确定CG周期内终端实际传输需要的TB数量M。如果M<N，那么无线接入网设备可以将N-M个TB中至少一个TB对应的资源(例如PUSCH、PUSCH传输机会、时隙或时域符号)分配给其他终端使用。如果M>N，那么无线接入网设备可以给该终端额外分配更多的资源用于数据传输。通过该实施方式，网络设备可以复用现有的缓存状态报告(buffer size report，BSR)机制上报LCG对应的实际发送的TB数量M或缓存大小中至少一项的信息，以便给网络设备调度做参考，提高资源利用率。
可以理解，上述cg-ActiveTB和Buffer Size仅是MAC CE中分别指示M和缓存大小的信息的一种可能的名称，本申请对此不作限定。
在终端向无线接入网设备发送上述MAC CE的一种可能的实施方式中，终端在第一时间单元向无线接入网设备发送上述用于指示M或缓存大小中至少一个的MAC CE。关于第一时间单元以及第一个TB对应的时间单元的描述可参考前文，此处不再赘述。通过该实施方式，终端可以通过MAC CE将CG周期中实际发送的TB数量M尽早地通知网络设备，使得网络设备可以及时获知M，以便根据实际的TB数量将未用的资源分配给其他终端使用，避免资源浪费。
终端可以在满足一定条件的情况下，在第一时间单元向无线接入网设备发送上述用于指示M或缓存大小中至少一个的MAC CE。
在一种可能的实施方式中，在满足前述条件1时，终端在第一时间单元向无线接入网设备发送上述MAC CE。关于条件1的描述可参考前文，此处不再赘述。通过该实施方式，当网络设备处理时延太大而导致CG周期内剩余的资源无法用于调度其他终端时，终端不必发送上述MAC CE，从而节省信令开销。
在另一种可能的实施方式中，在满足前述条件2时，终端在第一时间单元向无线接入网设备发送上述MAC CE。关于条件2的描述可参考前文，此处不再赘述。通过该实施方式，当配置的N个TB无法承载待传数据量，说明此时配置的资源不足，此时通过MAC CE通知网络设备，网络设备可以根据该MAC CE，分配额外的传输资源，以便及时传输剩余数据， 以降低传输时延。
在另一种可能的实施方式中，在满足下述条件3时，终端在第一时间单元向无线接入网设备发送上述MAC CE。
条件3：接收到预设参数或预设参数被配置为预设值。
在上述MAC CE基于LCH向无线接入网设备上报M或缓存大小中的至少一个的情况下，上述预设参数例如可以表示为。在一种可能的实现方法中，当接收到该enhanced-per-LCH-BSR，终端在第一时间单元向无线接入网设备发送MAC CE。在另一种可能的实现方法中，当该enhanced-per-LCH-BSR被设置为预设值时，终端在第一时间单元向无线接入网设备发送MAC CE，前述预设值例如可以是“true”、“enable”、“0”或“1”等。
在上述MAC CE基于LCG向无线接入网设备上报M或缓存大小中的至少一个的情况下，上述预设参数例如可以表示为enhanced-cg-BSR。在一种可能的实现方法中，当接收到该enhanced-cg-BSR，终端在第一时间单元向无线接入网设备发送MAC CE。在另一种可能的实现方法中，当该enhanced-cg-BSR被设置为预设值时，终端在第一时间单元向无线接入网设备发送MAC CE，前述预设值例如可以是“true”、“enable”、“0”或“1”等。
可以理解，上述enhanced-per-LCH-BSR和enhanced-cg-BSR仅是上述预设参数的一种可能的名称，本申请对此不作限定。
通过上述实施方式，终端设备可以根据网络设备的配置信息判断是否有必要向网络设备发送指示信息，避免了无效的信令指示和资源浪费。
在另一种可能的实施方式中，在满足前述条件1和条件3时，终端在第一时间单元向无线接入网设备发送上述MAC CE。关于条件1和条件3的描述可参考前文，此处不再赘述。通过该实施方式，终端设备可以根据网络设备的配置信息以及数据到达时间等信息判断是否有必要向网络设备发送指示信息，避免了无效的信令指示和资源浪费。
在另一种可能的实施方式中，在满足前述条件2和条件3时，终端在第一时间单元向无线接入网设备发送上述MAC CE。关于条件2和条件3的描述可参考前文，此处不再赘述。通过该实施方式，终端设备可以根据网络设备的配置信息以及待传输数据量等信息判断是否有必要向网络设备发送指示信息，避免了无效的信令指示和资源浪费。
