Description

通信方法及相关装置
本申请要求在2023年07月29日提交中国国家知识产权局、申请号为202310949354.X、申请名称为“通信方法及相关装置”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，尤其涉及一种通信方法及相关装置。
背景技术
在新空口(new radio，NR)系统中，终端设备可以通过缓存状态报告(buffer status report，BSR)通知接入网设备其有上行待传输数据，因此，接入网设备可以根据BSR为终端设备分配资源。当前，终端设备在上报BSR时，可以通过上报长BSR或短BSR对应的BSR表格上的索引值来通知接入网设备待传输数据的大小(或所处的BS区间)，但是当前长BSR或短BSR对应的BSR表格中的缓存状态(buffer status，BS)区间步长较大，因此，使得上报的待传输数据的数据量大小误差也较大，基于此，当前第三代合作伙伴计划(the 3rd generation partnership project，3GPP)版本18(Rel-18)的讨论中提出了可以引入一张新的BSR表格，该新的BSR表格中BS区间步长比较小，因此可以降低上报的待传输数据的数据量大小误差。除此之外，为了使接入网设备能够感知到数据的时延消耗情况和数据在终端设备侧的缓存情况，3GPP Rel-18还提出了终端设备可以向接入网设备上报数据的剩余时间(remaining time)和与剩余时间关联的待传输数据的数据量大小。
由此可知，在上述使用新的BSR表格场景和上报剩余时间的场景中，都需要上报终端设备的待传输数据的数据量大小，如果分别为这2种场景设计不同的上行信号来上报信息，将会增加空口资源消耗，且如果接入网设备先后收到两次不同的上报，可能会产生误解导致不能准确根据终端设备缓存进行调度。基于此，如何设计增强的上行信号成为亟待解决的问题。
发明内容
本申请提供了一种通信方法及相关装置，对上行信号的设计进行了增强，既支持剩余时间上报和新BS表格两种功能分别使用，也支持两者同时使用，避免上报的信息产生重复或冲突，同时也保障了网络灵活可配。
第一方面，本申请提供了一种通信方法，由终端设备执行，该终端设备可以为终端设备本身，也可以是终端设备中的模块或芯片。在该方法中，终端设备确定上行信号，并向网络设备发送所述上行信号。其中，所述上行信号包括至少一个逻辑资源的信息，所述至少一个逻辑资源包括第一逻辑资源，所述第一逻辑资源的信息包括第一字段和/或第二字段，所述第一字段用于指示所述第一逻辑资源中待传输数据的剩余时间信息，所述第二字段用于指示所述第一逻辑资源启用的第一BS表格，所述第一逻辑资源被配置的预设BS表格的数量为多个，所述第一BS表格包含于所述预设BS表格，所述第一BS表格包括多个BS区间；当所述第一逻辑资源被配置了剩余时间上报功能时，所述第一逻辑资源的信息包括所述第一字段；当所述预设BS表格的数量为多个时，所述第一逻辑资源的信息包括所述第二字段。
在本申请实施例中，上行信号可以为MACCE，RRC消息，PDCP controlPDU，或RLCcontrol PDU等，逻辑资源可以为逻辑信道组，逻辑信道，或DRB等，本申请实施例对此不做限制。其中，通过对上行信号的设计进行增强，使得其既支持剩余时间上报和新BS表格两种功能分别使用，也支持两者同时使用，进而可避免上报的信息产生重复或冲突，同时也保障了网络灵活可配。
在一种可能的设计中，当所述第一逻辑资源没有被配置剩余时间上报功能时，所述第一字段为预留字段；当所述预设BS表格的数量为1个时，所述第二字段为预留字段。
在该种实现方式下，通过改变第一字段和第二字段的含义，使得统一格式的MAC CE可以用于不同场景不同配置，表达了不同的含义。既支持剩余时间和新BS表格两种功能分别使用，也支持两者同时使用，避免上报的信息产生重复或冲突，也保障了网络灵活可配。
在一种可能的设计中，所述第一逻辑资源的信息还包括第三字段和/或第四字段，所述第三字段用于指 示所述第一字段是否存在，所述第四字段用于指示所述第二字段是否存在；
当所述第三字段指示所述第一字段存在时，所述第一逻辑资源的信息包括所述第一字段；或者，
当所述第三字段指示所述第一字段不存在时，所述第一逻辑资源的信息不包括所述第一字段；或者，
当所述第四字段指示所述第二字段存在时，所述第一逻辑资源的信息包括所述第二字段；或者，
当所述第四字段指示所述第二字段不存在时，所述第一逻辑资源的信息不包括所述第二字段。
在该种实现方式下，引入第三字段和第四字段实现不同配置时MAC CE包含的内容不同，以支撑不同的网络功能。相比于上述改变第一字段和第二字段的含义的实现方式，进一步减少了MAC CE中可能存在的无用字段，减少了空口资源消耗。通过第三字段和第四字段灵活组合，既支持剩余时间和新BS表格两种功能分别使用，也支持两者同时使用，避免上报的信息产生重复或冲突，也保障了网络灵活可配。

当所述第三字段指示所述第一字段不存在时，所述第一逻辑资源的信息不包括所述第一字段，且所述第一逻辑资源的信息包括所述第二字段。
在该种实现方式下，当第三字段指示第一字段不存在时，不需要单独的第四字段来指示第二字段是否存在，而是直接包括第二字段，这样可进一步减少无用字段，有利于减少空口资源消耗。

在一种可能的设计中，所述第一逻辑资源的信息还包括第五字段，所述第五字段用于指示所述第一逻辑资源中待传输数据的数据量大小所属的第一BS区间，所述第一BS区间包含于所述第一BS表格。
在该种实现方式下，第一逻辑资源的信息还可以包括用于指示第一逻辑资源中待传输数据的数据量大小的第五字段，当接入网设备获知后，可以合理为终端设备分配资源以用于传输待传输数据。可选的，第五字段也可以替换描述为BS value字段或BS value。

具体实施方式
下面结合附图对本申请具体实施例作进一步的详细描述。
本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等是用于区别不同对象，而不是用 于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，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。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上，“至少两个(项)”是指两个或三个及三个以上，“和/或”，用于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：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。
为了更好地理解本申请实施例，下面首先对本申请实施例涉及的系统架构进行介绍：
请参见图1，图1是本申请的实施例应用的通信系统的架构示意图。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。可选的，该通信系统1000还可以包括互联网300。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)。RAN 100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。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。
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，4G、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。RAN 100还可以是以上两种或两种以上系统融合的通信系统。
RAN节点110，有时也可以称为接入网设备，RAN实体或接入节点等，构成通信系统的一部分，用以帮助终端实现无线接入。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中基站110a和110b可以理解为具有基站功能的通信装置，终端120a-120j可以理解为具有终端功能的通信装置。
在一种可能的场景中，RAN节点可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、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、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节点分别实现基站的部分功能。例如，RAN节点可以是集中式单元(central unit，CU)，分布式单元(distributed unit，DU)，CU-控制面(control plane，CP)，CU-用户面(user plane，UP)，或者无线单元(radio unit，RU)等。这里的CU完成基站的无线资源控制协议和分组数据汇聚层协议(packet data convergence protocol，PDCP)的功能，还可以完成业务数据适配协议(service data adaptation protocol，SDAP)的功能；DU完成基站的无线链路控制层和介质访问控制(medium access control，MAC)层的功能，还可以完成部分物理层或全 部物理层的功能，有关上述各个协议层的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。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。
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。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端、移动设备(mobile equipment，ME)等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端的设备形态不做限定。
核心网中可以包括一个或多个功能实体(或称核心网网元，网元，实体等)。例如网络切片选择功能(network slice selection function，NSSF)、网络开放功能(network exposure function，NEF)、网络存储功能(network function repository function，NRF)、策略控制功能(policy control function，PCF)、统一数据管理(unified data management，UDM)、接入与移动性管理功能(access and mobility management function，AMF)、认证服务器功能(authentication server function，AUSF)、会话管理功能(session management function，SMF)等。
需要说明的是，以上功能实体仅是一个名字，名字本身对实体不构成限定。例如，该会话管理功能也有可能被替换为“会话管理功能实体”或其它名字。而且，该会话管理功能实体也可以对应一个包括除了会话管理功能外还有其他功能的实体。用户面功能也有可能被替换为“用户面功能实体”或其它名字，而且，该用户面功能实体也可以对应一个包括除了用户面功能外还有其他功能的实体。在此进行统一说明，以下不再赘述。
需要说明的是，本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，本申请实施例对此不做具体限定。
本申请中“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。
应当理解的是，本申请实施例中的终端设备可以是上述任意一种设备或芯片，具体此处不做限定。无论作为设备还是作为芯片，该终端设备都可以作为独立的产品进行制造、销售或者使用。在本实施例以及后续实施例中，仅以终端设备为例进行介绍。
应当理解的是，本申请实施例中用于实现接入网设备的功能的装置可以是接入网设备本身，也可以是能够支持接入网设备实现该功能的装置，例如芯片系统或可实现接入网设备功能的组合器件、部件，该装置可以被安装在接入网设备中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。在本实施例以及后续实施例中，仅以接入网设备为例进行介绍。
下面对本申请实施例涉及的相关技术特征进行解释说明。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、扩展现实(extended reality，XR)
XR是指各类由计算技术以及可穿戴设备生成的现实和虚拟相结合的环境，以及人机之间的交互，具体包括如下几种典型的形式：增强现实(augmented reality，AR)，混合现实(mixed reality，MR)和虚拟现实(virtual reality，VR)。
XR是目前工业领域重点考虑的5G多媒体应用之一。第三代合作伙伴项目(the 3rd generation  partnership project，3GPP)版本17(Rel-17)对XR的业务特征进行了建模分析，通常XR业务会按照一定的帧率周期性生成数据帧。以一个帧率为60fps的AR业务为例，每秒生成60帧视频图像，约每16.66ms出现一个视频帧，一个视频帧可能由多个数据包进行传输。
数据帧的大小并非是固定不变的，通常服从截断高斯分布。均值可以表示为mean＝R×1e6/F/8，其中F为帧率，R为数据流的速率；以F＝60fps，R＝20Mbps为例，mean＝41.67KBytes；通常数据帧的大小在0.5*mean到1.5*mean之间。
由于数据帧在编码时可能存在时延，导致每个周期的XR数据的到达空口侧的时间可能出现抖动(jitter)，即数据到达时间可能比预期周期时刻早或者晚，通常在数毫秒范围内波动。
XR业务通常有较高的时延要求。以上行AR业务为例，其典型包时延预算(packet delay budget，PDB)为30ms，即数据包到达终端设备接入层到数据包到达用户面功能网元(user plane function，UPF)的N6接口处，之间的传输时延上限为30ms。若数据包未在PDB要求时间内传输成功，则认为这个数据包已经超时并失去作用。
除了PDB，XR业务中还可能考虑PDU集合时延预算(PDU set delay budget，PSDB)，其含义与PDB类似，定义了一组数据包(例如一个PDU set)的传输时延上限。对于上行，指从PDU set中的第一个数据包到达终端设备接入层到最后一个数据包到达UPF的N6接口的时间上限，对于下行则相反。
网络应该尽量在时延预算内完成数据调度和传输，避免数据超时从而影响服务体验。
2、缓存状态报告(bufferstatusreport，BSR)
如果终端设备没有上行数据待发送，接入网设备无需为终端设备分配资源，否则会造成资源浪费。在NR中，终端设备可以通过BSR/调度请求(scheduling request，SR)通知接入网设备有上行待传输数据。
终端设备的每个逻辑信道(logical channel，LCH)可以被分配到一个逻辑信道组(logical channel group，LCG)中。NR中可以配置的LCG最大数目为8个。在NR中，当发生如下事件时，终端设备可以触发BSR：
(1)属于一个LCG的LCH有上行数据到达，且其他LCG包含的LCH均没有待传输数据，或者该LCH的优先级比其他LCG包含的有待传输数据的LCH的优先级都高；此情形触发的BSR叫做“常规BSR(Regular BSR)”；
(2)有上行资源可用，且剩余padding比特(bit)大于等于BSR媒体访问控制层控制单元(medium access control control element，MAC CE)加上MAC CE子头的大小；此情形触发的BSR叫做“填充BSR(Padding BSR)”；
(3)重传BSR定时器(retxBSR-Timer)超时，并且有至少一个包含在LCG中的LCH存在上行待传输数据；此情形触发的BSR叫做“Regular BSR”；
(4)周期BSR定时器(periodicBSR-Timer)超时；此情形触发的BSR叫做“Periodic BSR”。
当终端设备触发了至少一个BSR且未被取消时：
(1)如果有可用的上行新传资源，且该上行资源可以容纳BSR MAC CE加上MAC CE子头大小时：终端设备可以生成一个BSR MAC CE；如果所有生成的BSR都不是长截断BSR或短截断BSR，则终端设备启动/重启periodicBSR-Timer；终端设备启动/重启retxBSR-Timer。
(2)如果触发了Regular BSR且logicalChannelSR-DelayTimer未运行：没有可用的新传上行资源，或者终端设备被配置有配置上行授权(configured uplink grants)且Regular BSR是一个logicalChannelSR-Mask参数被设置为false的LCH触发的，或者可用于新传的上行资源无法满足触发了BSR的LCH对应的LCP映射限制时，终端设备触发SR。
3、BSR MAC CE
当终端设备生成BSR MAC CE时，具体的BSR MAC CE格式如下图2和图3所示。图2所示的短BSR或短截断BSR MAC CE，包含一个3比特的LCG ID字段和5比特的缓存大小(Buffer Size)字段，其中LCG ID指示后面上报的Buffer Size对应的LCG。图3所示的长BSR或长截断BSR MAC CE，包含一个8比特的位图(bitmap)，以及0个或者多个Buffer Size字段。对于长BSR MAC CE，bitmap中的第i个比特LCGi表示LCG i是否有对应的Buffer Size字段存在；对于长截断BSR MAC CE，bitmap中的第i个比特LCGi表示LCG i是否有待传输数据存在，此时后续不一定存在LCG i对应的Buffer Size字段。
具体终端设备选择何种BSR MAC CE格式上报，取决于触发的BSR类型、有待传输数据的LCG的数目、可用剩余资源的大小等。
(1)对于Regular BSR和Periodic BSR：
当存在大于一个的LCG有待传输数据时，上报长BSR；
当只有一个LCG有待传输数据时，上报短BSR；
(2)对于Padding BSR：
①当padding资源等于短BSR加其子头的大小时：
当存在大于一个的LCG有待传输数据时，上报短截断BSR；
当只有一个LCG有待传输数据时，上报短BSR；
②当padding资源大于短BSR加其子头的大小，且小于长BSR加其子头的大小时：
当存在大于一个的LCG有待传输数据时，上报长截断BSR；
当只有一个LCG有待传输数据时，上报短BSR；
③当padding资源大于等于长BSR加其子头大小时，上报长BSR；
终端设备可以通过上报长BSR或短BSR对应的BSR表格上的索引值来通知接入网设备待传输数据的大小(所处的区间)。其中，短BSR和短截断BSR对应的BSR表格如表1所示，长BSR和长截断BSR对应的BSR表格如表2所示，其中，Index表示索引值，缓存状态(bufferstatus，BS)值(BS value)表示待传输数据的大小(所处的区间)，单位为字节(Byte)。
表1短BSR和短截断BSR对应的BSR表格
表2长BSR和长截断BSR对应的BSR表格

由上述表1可知，对于短BSR和短截断BSR对应的BSR表格，其最大BS区间的含义是“大于150KBytes”，当实际数据大小超过150Kbytes时，短BSR无法准确反映，这对于XR业务的数据帧大小来说误差过大，容易引起资源浪费或调度延迟。而对于长BSR和长截断BSR对应的BSR表格，其BS区间的步长随着索引值的增大而增加，这里BS区间步长即相邻索引值对应的BS value之间的差值。例如在索引值172(对应约0.5MBytes)～190(对应约1.5MBytes)之间，BS区间步长已经达到30～90Kbytes，使得XR业务上报BSR时容易存在较大的误差，导致资源浪费。基于此，当前3GPPRel-18的讨论中同意为了XR业务在标准中引入一张新的BSR表格，该新的BSR表格中BS区间步长比较小。支持该新表格的UE在上报BSR时，可以根据网络配置或其它原则(如根据待传输数据量大小是否落在新表格范围内)确定选择新旧BSR表格中的一个，并使用其中的BS索引向网络上报对应的BS值。
除此之外，为了使接入网设备能够感知到数据的时延消耗情况和数据在终端设备中的缓存情况，3GPP Rel-18还提出了终端设备可以向接入网设备上报数据的剩余时间(remaining time)和与剩余时间关联的待传输数据的数据量大小。剩余时间指数据还可以用于空口传输的时间，例如可以是PDB或PSDB减去数据已经在终端设备缓存中停留的时间。通常来说，剩余时间结束后，数据可能因为超时而被丢弃，因此终端设备通过提前上报剩余时间，可以辅助接入网设备及时调度数据，避免超时。例如，终端设备通知接入网设备其缓存中还有500bytes的数据剩余时间为10ms，另有1000bytes的数据剩余时间为20ms，则接入网设备可以先为终端设备提供500bytes的传输资源使其能够传输紧急数据避免其超时，而对于剩下的1000bytes，接入网设备可以稍晚一些再调度，从而先腾出资源服务其它更紧急的用户。
由此可知，在上述使用新的BSR表格场景和上报剩余时间的场景中，都需要上报终端设备的待传输数据的数据量大小，如果分别为这2种场景设计不同的上行信号来上报信息，将会增加空口资源消耗，且如果接入网设备先后收到两次不同的上报，可能会产生误解导致不能准确根据终端设备缓存进行调度。
基于此，本申请提出了一种通信方法，其对上行信号的设计进行了增强，提高了上行信号的适用性。
需要说明的是，本申请实施例中描述的剩余时间区间也可以替换描述剩余时间范围，其中剩余时间区间“t1～t2”可以理解为(t1,t2]，或者，也可以理解为[t1,t2)，或者，也可以理解为(t1,t2)，或者，也可以理解为[t1,t2]。其中，(t1,t2]相当于t1＜t≤t2；[t1,t2)相当于t1≤t＜t2；(t1,t2)相当于t1＜t＜t2；[t1,t2]相当于t1≤t≤t2。为方便描述，以下本申请实施例主要以“t1～t2”表示(t1,t2]为例进行示意性说明，例如剩余时间区间0～10ms表示(0,10]，剩余时间区间10～20ms表示(10,20]。
在本申请实施例中，预设BS表格也可以替换描述为可用(available)BS表格或候选BS表格等，本申请对此不做限制。
下面对本申请提供的通信方法及通信装置进行详细介绍：
请参见图4，图4是本申请实施例提供的通信方法的流程示意图。如图4所示，该通信方法包括如下步骤S401～S402。图4所示的方法执行主体可以为终端设备和接入网设备，或者，图4所示的方法执行主体也可以为终端设备中的芯片和接入网设备中的芯片，为方便描述，图4主要以终端设备和接入网设备为方法的执行主体为例进行说明。需要说明的是，图4是本申请的方法实施例的示意性流程图，示出了该方法的详细的通信步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者图4中的各种操作的变形。此外，图4中的各个步骤可以分别按照与图4所呈现的不同的顺序来执行，并且有可能并非要执行图4中的全部操作。其中：
S401、终端设备确定上行信号。
这里，上行信号可以是MAC CE，无线资源控制(radio resource control，RRC)消息，分组数据汇聚协议(packet data convergence protocol，PDCP)控制协议数据单元(protocol data unit，PDU)(即PDCP control PDU)，或无线链路控制(radio link control，RLC)控制PDU(即RLC control PDU)等，本申请对此不做限制。为便于理解，后文主要以上行信号为MAC CE为例进行示意性说明。
其中，上述上行信号包括至少一个逻辑资源的信息(或描述为至少一个逻辑资源的BS信息)，一个逻辑资源中包括至少一份待传输数据(即一份或者多份待传输数据)，一份待传输数据对应一个剩余时间，通常来说，一份待传输数据可以包括一个或多个数据包。由于每个逻辑资源的信息格式类似，因此，为方便描述，本申请实施例主要以该至少一个逻辑资源中一个逻辑资源(以下描述为第一逻辑资源)的信息设计为例进行说明。其中，第一逻辑资源的信息包括第一字段和/或第二字段。第一字段用于指示第一逻辑资源中待传输数据的剩余时间信息。第二字段用于指示第一逻辑资源启用的第一BS表格，第一逻辑资源被配置的预设BS表格的数量为多个(即两个或者两个以上)，第一BS表格包含于预设BS表格，第一BS表格包括多个BS区间。通常来说，当第一逻辑资源被配置了剩余时间上报功能时，第一逻辑资源的信息包括第一字段；当预设BS表格的数量为多个时，第一逻辑资源的信息包括第二字段；当第一逻辑资源被配置了剩余时间上报功能，且预设BS表格的数量为多个时，第一逻辑资源的信息包括第一字段和第二字段。
示例性地，当BS value字段的长度固定为8bit时，本申请实施例中涉及的预设BS表格可以为长BSR和长截断BSR对应的BSR表格，其中当预设BS表格的数量为1个时，该预设BS表格可以为上述表2所示的表格。当该预设BS表格的数量为2个时，该2个预设BS表格中的一个预设BS表格可以为上述表2所示的表格，另一个预设BS表格可以是为了XR业务在标准中引入的一张新的BSR表格，该新的表格可以包含256行。当该预设BS表格的数量为K(K≥3)个时，该K个预设BS表格中的一个预设BS表格可以为上述表2所示的表格，另外(K-1)个预设BS表格可以是为了XR业务在标准中引入的(K-1)张新的BSR表格。为方便描述，后文可将表2所示的表格描述为旧表格，将为了XR业务在标准中新引入的一个或多个表格称为新表格。基于此，本申请实施例中“预设BS表格的数量为多个”也可以替换描述为“配置了新的BS表格”，“预设BS表格的数量为1个”也可以替换描述为“没有/未配置新的BS表格”。
可选的，第一逻辑资源的信息还包括第五字段，该第五字段用于指示第一逻辑资源中待传输数据的数据量大小所属的第一BS区间，第一BS区间包含于第一BS表格。
其中，逻辑资源可以是逻辑信道组，逻辑信道，或数据无线承载(data radio bearer，DRB)等，本申请对此不做限制。在一种实现中，当逻辑资源为逻辑资源组时，MAC CE中可以包含逻辑信道组标识(LCG ID)，用于表示上报的BS信息来自哪个逻辑信道组，或者，MAC CE中可以包含逻辑信道组的比特位图(LCG bitmap)，其中每个比特位对应一个逻辑信道组，当对应比特位的值为“1”时，表示MAC CE中包 含对应LCG的BS信息。在另一种实现中，当逻辑资源为逻辑信道时，MAC CE中可以包含逻辑信道标识(LCH ID)，用于表示上报的BS信息来自哪个逻辑信道，或者，MAC CE中可以包含逻辑信道的比特位图(LCH bitmap)，其中每个比特位对应一个逻辑信道，当对应比特位的值为“1”时，表示MAC CE中包含对应LCH的BS信息。在又一种实现中，当逻辑资源为DRB时，MAC CE中可以包含DRB标识(DRB ID)，用于表示上报的BS信息来自哪个DRB，或者，MAC CE中可以包含DRB的比特位图(DRB bitmap)，其中每个比特位对应一个DRB，当对应比特位的值为“1”时，表示MAC CE中包含对应DRB的BS信息。为便于理解，后文主要以逻辑资源为逻辑信道组或逻辑信道为例进行示意性说明。
可选的，本申请实施例中的第一字段也可以描述为剩余时间指示字段(remaining time indication字段或remaining time indication)，第二字段也可以描述为BS表格指示字段(BS table indication字段或BS table indication)，第五字段也可以描述为BS value字段或BS value。
下面分别介绍MAC CE的不同设计方式：
在一种实现方式1中，当第一逻辑资源没有被配置剩余时间上报功能时，第一字段为预留字段(或者描述为第一字段被视为保留比特(reserved bits)，或第一字段存在但不具备任何意义)，当预设BS表格的数量为1个时，第二字段为预留字段(或描述为第二字段被视为reserved bits，或第二字段存在但不具备任何意义)。
举例来说，请参见图5，图5是本申请实施例提供的MAC CE的一格式示意图。以上行信号为MAC CE，逻辑资源为逻辑信道组为例，如图5所示，该MAC CE中包括如下各个字段：
1、逻辑信道组的标识(LCG ID)字段：逻辑信道组标识，表示该MAC CE上报了哪个逻辑信道组的信息，例如后文可记为LCG x。可选的，LCG ID字段也可以替换为LCH ID字段，表示该MAC CE上报了哪个逻辑信道的信息，例如后文可记为LCH x，或者，也可以替换为DRB ID字段等，表示该MAC CE上报了哪个数据无线承载的信息，例如可记为DRB x。
2、第一字段：当网络为LCG x配置了剩余时间上报功能时，该第一字段用于指示LCG x中待传输数据的剩余时间；当网络没有为LCG x配置剩余时间上报功能时，该第一字段被视为reserved bits，此时其任何取值都没有意义。
3、第二字段：当预设BS表格的数量为多个时，该第二字段用于指示LCG x的BS value信息所参考的BS表格；当预设BS表格的数量为1个时，该第二字段被视为reserved bits，此时其任何取值都没有意义。
4、BS value字段(或称为第五字段)：缓存数据量的索引号，用于在对应的BS表格中根据该索引号确定LCG x的待传输数据量。MAC CE中至少存在一个BS value字段，也有可能存在多个BS value字段。
5、保留/预留比特(即R)：没有具体含义，用于使MAC CE格式上字节对齐，不一定存在。
应理解，图5给出的例子只考虑了一个LCG的信息的上报，如果有多个LCG存在BS信息需要上报，可以分别在单独的MAC CE中上报，或者，也可以在一个MAC CE中同时携带多个LCG的信息。其中，在一个MAC CE中同时携带多个LCG信息的MAC CE格式可以有多种形式，例如图6中(a)和(b)分别给出了两种可能的实现。如图6中(a)所示，MAC CE中包括多个LCG的信息，其中每个LCG的信息中均可以包括LCG ID，第一字段，第二字段和一个或者多个BS value字段。如图6中(b)所示，MAC CE中包含一个8比特的bitmap，表示对应的LCG是否有信息上报，例如LCG 0的比特位的值为“1”，则表示该MAC CE中包含LCG 0的信息。其中，每个比特位的值为“1”的LCG对应的信息包括第一字段，第二字段和一个或者多个BS value字段。
可选的，当一个MAC CE中包含多个LCG的信息时，各LCG的信息可以按照如下规则之一排列：
规则一：按照LCG标识的大小排列，例如按照LCG标识从小到大的顺序在MAC CE中排列，或者，按照LCG标识从大到小的顺序在MAC CE中排列。
规则二：按照LCG的优先级排列，例如按照LCG的优先级从高到低排列。这里LCG的优先级可以是根据LCG中包含的LCH的优先级确定的，例如LCG的优先级等于包含的LCH的最高优先级。
规则三：按照剩余时间的大小排列，例如按照剩余时间从小到大排列。如果LCG的BS信息中包含剩余时间，则将最小剩余时间更小的LCG排在前面。不包含剩余时间信息的LCG排在所有含剩余时间信息的LCG之后。如果出现多个LCG剩余时间相同的情况，则按照LCG标识大小或LCG优先级排列。
需要说明的是，实现方式1通过改变第一字段和第二字段的含义，使得统一格式的MAC CE可以用于不同场景不同配置，表达了不同的含义。既支持剩余时间和新BS表格两种功能分别使用，也支持两者同时使用，避免上报的信息产生重复或冲突，也保障了网络灵活可配。
在一种实现方式2中，第一逻辑资源的信息还包括第三字段和/或第四字段。其中第三字段用于指示第一字段是否存在，第四字段用于指示第二字段是否存在。也就是说，第三字段和第四字段为2个标志字段，其中一个标志字段用于指示MAC CE中是否含有第一字段，另一个标志字段用于指示MAC CE中是否含有第二字段。
其中，在实现方式2下，当第三字段指示第一字段存在时，第一逻辑资源的信息包括第一字段，当第三字段指示第一字段不存在时，第一逻辑资源的信息不包括第一字段。当第四字段指示第二字段存在时，第一逻辑资源的信息包括第二字段，当第四字段指示第二字段不存在时，第一逻辑资源的信息不包括第二字段。通常来说，当第一逻辑资源被配置了剩余时间上报功能时，第三字段指示第一字段存在，当第一逻辑资源没有被配置剩余时间上报功能时，第三字段指示第一字段不存在。当预设BS表格的数量为多个时，第四字段指示第二字段存在，当预设BS表格的数量为1个时，第四字段指示第二字段不存在。
举例来说，请参见图7，图7是本申请实施例提供的MAC CE的另一格式示意图。以上行信号为MAC CE，逻辑资源为逻辑信道为例，如图7所示，该MAC CE中包括如下各个字段：
1、逻辑信道组的标识(LCG ID)字段：逻辑信道组标识，表示该MAC CE上报了哪个逻辑信道组的信息，例如后文可记为LCG x。可选的，LCG ID字段也可以替换为LCH ID字段，表示该MAC CE上报了哪个逻辑信道的信息，例如后文可记为LCH x，或者，也可以替换为DRB ID字段等，表示该MAC CE上报了哪个数据无线承载的信息，例如可记为DRB x。
2、第三字段：用于指示MAC CE中是否含有指示剩余时间的字段，即图中的第一字段。例如，当第三字段取值为“1”时，表示第一字段存在，当第三字段取值为“0”时，表示第一字段不存在。
3、第四字段：用于指示MAC CE中是否含有指示BS表格的字段，即图中的第二字段。例如，当第四字段取值为“1”时，表示第二字段存在，当第四字段取值为“0”时，表示第二字段不存在。
4、第一字段：当第三字段指示第一字段存在时(例如当第三字段取值为“1”时)，第一字段存在。第一字段用于指示LCG x中待传输数据的剩余时间。
5、第二字段：当第四字段指示第二字段存在时(例如当第四字段取值为“1”时)，第一字段存在。第二字段用于指示LCG x的BS value信息所参考的BS表格。
6、BS value字段(或称为第五字段)：缓存数据量的索引号，用于在对应的BS表格中根据该索引号确定LCG x的待传输数据量。MAC CE中至少存在一个BS value字段，也有可能存在多个BS value字段。
应理解，图7给出的例子只考虑了一个LCG的信息的上报，如果有多个LCG存在BS信息需要上报，可以分别在单独的MAC CE中上报，或者，也可以在一个MAC CE中同时携带多个LCG的信息。其中，在一个MAC CE中同时携带多个LCG信息的MAC CE格式可以有多种形式，例如图8中(a)和(b)分别给出了两种可能的实现。如图8中(a)所示，MAC CE中包括多个LCG的信息，其中每个LCG的信息中均可以包括LCG ID，第三字段，第四字段，第一字段(可选)，第二字段(可选)和一个或者多个BS value字段。如图8中(b)所示，MAC CE中包含三个8比特的bitmap，其中：第一行中的8比特bitmap表示对应的LCG是否有信息上报，例如LCG 0的比特位的值为“1”，则表示该MAC CE中包含LCG 0的信息。第二行中的8比特bitmap表示对应LCG的第三字段，如果第一行中LCG对应比特位的值为“0”，则这里对应的第三字段的取值无意义(或对应的第三字段为预留比特)。例如如果第一行中LCG 1的比特位的值为“0”，则第二行中LCG 1的比特位无意义，又例如如果第一行中LCG 0的比特位的值为“1”，则第二行中LCG 0的比特位用于指示LCG 0信息中是否含有第一字段。第三行中的8比特bitmap表示对应LCG的第四字段，如果第一行中LCG对应比特位的值为“0”，则这里对应的第四字段的取值无意义(或对应的第四字段为预留比特)。例如如果第一行中LCG 1的比特位的值为“0”，则第三行中LCG 1的比特位无意义，又例如如果第一行中LCG 0的比特位的值为“1”，则第三行中LCG 0的比特位用于指示LCG 0信息中是否含有第二字段。第一行中每个比特位的值为“1”的LCG对应的信息包括第一字段(可选)，第二字段(可选)和一个或者多个BS value字段。
可选的，当一个MAC CE中包含多个LCG的信息时，各LCG的信息可以按照实现方式1中描述的三种规则中任一种规则进行排列。
可选的，在实现方式2下，当第一逻辑资源的信息包括第三字段(且不包括第四字段)时，若第三字段指示第一字段不存在，那么第一逻辑资源的信息不包括第一字段且包括第二字段。也就是说，当第三字段指示第一字段不存在时，不需要单独的第四字段来指示第二字段是否存在，而是直接包括第二字段，该第二字段用于指示所用的BS表格，这样可进一步减少无用字段，有利于减少空口资源消耗。
举例来说，请参见图9，图9是本申请实施例提供的MAC CE的另一格式示意图。以上行信号为MAC  CE，逻辑资源为逻辑信道为例，MAC CE包括第三字段，且第三字段的取值为“0”，表示不包括第一字段且包括第二字段。
需要说明的是，实现方式2引入第三字段和第四字段实现不同配置时MAC CE包含的内容不同，以支撑不同的网络功能。相比于实现方式1进一步减少了MAC CE中可能存在的无用字段，减少了空口资源消耗。通过第三字段或第四字段灵活组合，既支持剩余时间和新BS表格两种功能分别使用，也支持两者同时使用，避免上报的信息产生重复或冲突，也保障了网络灵活可配。
在一种实现方式3中，当第一逻辑资源被配置了剩余时间上报功能，且预设BS表格的数量为1个时，第一逻辑资源的信息包括第一字段，且不包括第二字段。当第一逻辑资源没有被配置剩余时间上报功能，且预设BS表格的数量为多个时，第一逻辑资源的信息包括第二字段，且不包括第一字段。当第一逻辑资源被配置了剩余时间上报功能，且预设BS表格的数量为多个时，第一逻辑资源的信息包括第一字段和第二字段。
举例来说，请参见图10，图10是本申请实施例提供的MAC CE的另一格式示意图。以上行信号为MAC CE，逻辑资源为逻辑信道为例：
如图10中(a)所示：当网络配置了剩余时间上报功能，且预设BS表格的数量为1个时，第一逻辑资源的信息包括第一字段，且不包括第二字段。可理解的，MAC CE中还可以BS value字段(或称为第五字段)。
如图10中(b)所示：当网络没有配置剩余时间上报功能，且预设BS表格的数量为多个时，MAC CE中包括第二字段，且不包括第一字段。可理解的，MAC CE中还可以BS value字段。
如图10中(c)所示：当网络配置了剩余时间上报功能，且预设BS表格的数量为多个时，MAC CE中包括第一字段和第二字段。可理解的，MAC CE中还可以BS value字段。
应理解，图10给出的例子只考虑了一个LCG的信息的上报，如果有多个LCG存在BS信息需要上报，可以分别在单独的MAC CE中上报，或者，也可以在一个MAC CE中同时携带多个LCG的信息。其中，在一个MAC CE中同时携带多个LCG信息的MAC CE格式可以有多种形式，例如图11～图13中的(a)和(b)分别给出了不同网络配置下的两种可能的实现。
如图11中(a)所示，每个LCG的信息中均可以包括LCG ID，第一字段和一个或者多个BS value字段。如图11中(b)所示，MAC CE中包含一个8比特的bitmap，表示对应的LCG是否有信息上报，例如LCG 0的比特位的值为“1”，则表示该MAC CE中包含LCG 0的信息。其中，每个比特位的值为“1”的LCG对应的信息包括第一字段和一个或者多个BS value字段。
如图12中(a)所示，每个LCG的信息中均可以包括LCG ID，第二字段和一个或者多个BS value字段。如图12中(b)所示，MAC CE中包含一个8比特的bitmap，表示对应的LCG是否有信息上报，例如LCG 0的比特位的值为“1”，则表示该MAC CE中包含LCG 0的信息。其中，每个比特位的值为“1”的LCG对应的信息包括第二字段和一个或者多个BS value字段。
如图13中(a)所示，每个LCG的信息中均可以包括LCG ID，第一字段，第二字段和一个或者多个BS value字段。如图13中(b)所示，MAC CE中包含一个8比特的bitmap，表示对应的LCG是否有信息上报，例如LCG 0的比特位的值为“1”，则表示该MAC CE中包含LCG 0的信息。其中，每个比特位的值为“1”的LCG对应的信息包括第一字段，第二字段和一个或者多个BS value字段。
可选的，当一个MAC CE中包含多个LCG的信息时，各LCG的信息可以按照实现方式1中描述的三种规则中任一种规则进行排列。
需要说明的是，实现方式3直接为MAC CE设计多种不同的格式，终端设备根据网络配置选择对应的格式，不需要携带额外的指示信息，进一步减少了空口资源消耗。
可选的，在上述实现方式1～实现方式3中，当上行资源受限/不足导致无法完整传输一个包含了多个LCG信息的MAC CE时，终端设备可以对MAC CE进行截断处理，即生成一个更短的MAC CE(truncated MAC CE)，以便尽量在资源范围内传递信息给接入网设备。具体的，终端设备可以按照上述多个LCG的顺序，以LCG的信息为单位，当发现再增加一个LCG的信息后，MAC CE的大小将超过可用传输资源大小时，停止向MAC CE中加入更多LCG信息，即生成一个只包含了部分LCG的BS信息的MAC CE。对于这种情况，终端设备可以在MAC CE中携带信息表明存在部分LCG有待传输数据但其相关BS信息未被包含在此MAC CE中。例如在图6中(b)，图8中(b)，图11中(b)，图12中(b)和图13中(b)所示的MAC CE格式中，如果发生截断，例如假设LCG 7有待传输数据但BS信息没能被包含在MAC CE中，则图中第一行LCG 7对应的比特位依然可以填“1”。
下面针对上述实现方式1～实现方式3中涉及的第一字段，第二字段，以及第五字段(即BS value字段)的几种可能形式分别进行说明：
如前述描述的，第一逻辑资源中可以包括至少一份待传输数据，其中一份待传输数据对应一个剩余时间。
(一)第一字段指示第一逻辑资源中待传输数据的剩余时间信息，可能包括如下几种情况：
情况1、第一字段用于指示至少一份待传输数据对应的剩余时间中的最小剩余时间，也就是说，第一字段可以指示具体的最小剩余时间的数值，例如3ms，表示第一逻辑资源(例如LCG x)中数据的最小剩余时间为3ms。
情况2、第一字段用于指示至少一份待传输数据对应的剩余时间中的最小剩余时间所属的剩余时间区间。也就是说，第一字段可以指示某个剩余时间区间，例如指示最小剩余时间所属的剩余时间区间。举个例子，假设网络和终端设备通过预定义或预配置的方式事先约定好0～5ms、5～10ms、10～15ms、15～20ms四个剩余时间区间，其中第一字段包含2bit，该2bit的取值为“00”时，表示第一逻辑资源中数据的最小剩余时间在0～5ms范围内；该2bit的取值为“01”时，表示第一逻辑资源中数据的最小剩余时间在5～10ms范围内；该2bit的取值为“10”时，表示第一逻辑资源中数据的最小剩余时间在10～15ms范围内；该2bit的取值为“11”时，表示第一逻辑资源中数据的最小剩余时间在15～20ms范围内。再举个例子，假设第一字段包含4bit，该4bit中每个bit位对应一个剩余时间区间，网络和终端设备通过预定义或预配置的方式事先约定好从最低比特位开始，按比特位递增的顺序分别对应0～5ms、5～10ms、10～15ms、15～20ms四个剩余时间区间，其中，当对应比特位的值为“1”时，表示第一逻辑资源中数据的最小剩余时间在该比特位对应的剩余时间区间中。
例如假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为7ms，待传输数据3对应的剩余时间为9ms，因此，第一字段可以为“0001”，表示第一逻辑资源中数据的最小剩余时间(即3ms)所在的剩余时间区间为0～5ms。
又例如假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为8ms，待传输数据3对应的剩余时间为18ms，因此，第一字段可以为“0001”，表示第一逻辑资源中数据的最小剩余时间(即3ms)所在的剩余时间区间为0～5ms。
情况3、第一字段用于指示至少一份待传输数据对应的剩余时间分别所属的剩余时间区间。也就是说，第一字段可以指示多个剩余时间区间，例如第一字段包含2bit，通过预定义或预配置的方式事先约定其中低位比特代表了剩余时间区间0～10ms，高位比特代表了剩余时间区间10～20ms，当对应bit为“1”时，表示第一逻辑资源中存在剩余时间在对应剩余时间区间范围内的数据。
例如，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为7ms，待传输数据3对应的剩余时间为9ms，因此，第一字段可以为“01”，表示第一逻辑资源中存在剩余时间在0～10ms范围内的数据，而不存在剩余时间在10～20ms范围内的数据。
又例如，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为8ms，待传输数据3对应的剩余时间为18ms，因此，第一字段可以为“11”，表示第一逻辑资源中既存在剩余时间在0～10ms范围内的数据，又存在剩余时间在10～20ms范围内的数据。
(二)第二字段指示第一逻辑资源启用的第一BS表格，可能包括如下几种情况：
情况(1)、第二字段指示一个第一BS表格，第一BS表格为多个预设BS表格中的一个，第一逻辑资源的信息中的所有BS value字段所指示的第一BS区间参考第一BS表格。
例如，假设预设BS表格的数量为2个(即1个旧表格和1个新表格)，那么第二字段可以只有1bit，用于表示该MAC CE中与第一逻辑资源相关的所有BS value字段应该参考新的BS表格查找，还是参考旧的BS表格查找，例如“1”表示新表格，“0”表示旧表格，或者，“0”表示新表格，“1”表示旧表格。为方便理解，当预设BS表格的数量为2个时，本申请实施例皆以“1”表示新表格，“0”表示旧表格为例进行示意性说明。
又例如，假设预设BS表格的数量为3个(即1个旧表格和2个新表格)，那么第二字段可以有2bit，用于表示该MAC CE中与第一逻辑资源相关的所有BS value字段应该参考哪个/哪张表格。例如，“00”表示旧 表格，“01”表示新表格1，“10”表示新表格2。
情况(2)、第二字段指示多个第一BS表格，多个第一BS表格中任一个第一BS表格为多个预设BS表格中的一个，多个第一BS表格的数量等于BS value字段的数量(此时BS value字段的数量为多个，例如BS value字段的数量等于第一字段指示的剩余时间区间的个数)，多个第一BS表格与多个BS value字段一一对应，一个BS value字段指示的第一BS区间参考对应的一个第一BS表格。
例如，第二字段可以有多个比特位，且第二字段包括的比特位数与MAC CE中可能包含的BS value字段的个数相同，每个比特位对应一个BS value，用于表示该BS value应该参考新表格还是旧表格查找。举个例子，如果是情况(2)，假设MAC CE中包括2个BS value字段(BS value 1和BS value 2)，其中BS value 1取值“01000000(64)”，BS value 2取值“00000111(7)”，因此，第二字段也包括2bit，通过预定义或预配置的方式事先约定其中低位比特对应BS value 1，高位比特对应BS value 2。如果第二字段的值为“10”，则表示BS value 1中的索引应该参考旧表格查找，BS value 2中的索引应该参考新表格查找。
情况(3)、第二字段指示多个第一BS表格，多个第一BS表格中任一个第一BS表格为多个预设BS表格中的一个，多个第一BS表格的数量等于第一字段包括的比特位数(此时第一字段为上述情况3)，多个第一BS表格与第一字段包括的多个比特位一一对应，一个比特位表示该比特位对应的一个剩余时间区间所关联的BS value字段指示的第一BS区间参考对应的一个第一BS表格。
例如，第二字段有多个比特位，且第二字段包括的比特位数与第一字段的比特位数(即第一字段为情况3)相同，当第一字段中的每个比特对应一个剩余时间区间时，第二字段中的每个比特对应与该剩余时间区间关联的BS value(例如BS value字段为情况④)，用于表示其参考新表格还是旧表格，如果第一字段中的某个比特位为“0”(即表示不存在该剩余时间区间的数据)，则第二字段中对应的比特位没有意义。
举个例子，如果是情况(3)，假设MAC CE中第一字段包含2bit，通过预定义或预配置的方式事先约定其中低位比特代表了剩余时间区间0～10ms，高位比特代表了剩余时间区间10～20ms，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为7ms，待传输数据3对应的剩余时间为9ms，因此，第一字段可以为“01”，表示第一逻辑资源中存在剩余时间在剩余时间区间0～10ms范围内的数据，而不存在剩余时间在区间10～20ms范围内的数据。基于此，还可以确定第二字段也包括2bit(这是因为第二字段包括的比特位数与第一字段的比特位数相同)，其中第二字段中的低位比特对应第一字段中的低位比特，第二字段中的高位比特对应第一字段中的高位比特。如果第二字段的值为“10”，再结合第一字段的取值“01”，可以确定第二字段中高位比特的取值(即第二字段中的“1”)没有意义(这是因为第一字段中高位比特的取值为“0”，表示不存在该剩余时间区间10～20ms的数据)，第二字段中低位比特的取值(即第二字段中的“0”)表示旧表格，用于指示与剩余时间区间0～10ms关联的BS value中的索引应该参考旧表格查找，即待传输数据1，待传输数据2和待传输数据3的数据量大小之和应该参考旧表格查找。
又举个例子，如果是情况(3)，假设MAC CE中第一字段包含2bit，通过预定义或预配置的方式事先约定其中低位比特代表了剩余时间区间0～10ms，高位比特代表了剩余时间区间10～20ms，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1对应的剩余时间为3ms，待传输数据2对应的剩余时间为8ms，待传输数据3对应的剩余时间为18ms，因此，第一字段可以为“11”，表示第一逻辑资源中既存在剩余时间在剩余时间区间0～10ms范围内的数据，又存在剩余时间在区间10～20ms范围内的数据。基于此，还可以确定第二字段也包括2bit(这是因为第二字段包括的比特位数与第一字段的比特位数相同)，其中第二字段中的低位比特对应第一字段中的低位比特，第二字段中的高位比特对应第一字段中的高位比特。如果第二字段的值为“10”，再结合第一字段的取值“11”，可以确定第二字段中高位比特的取值(即“1”)，表示新表格，用于指示与剩余时间区间10～20ms关联的BS value中的索引应该参考新表格查找，即待传输数据3的数据量大小参考新表格查找；第二字段中低位比特的取值(即“0”)表示旧表格，用于指示与剩余时间区间0～10ms关联的BS value中的索引应该参考旧表格查找，即待传输数据1和待传输数据2的数据量大小之和应该参考旧表格查找。
可选的，如果存在不止一张新BS表格(即存在2个或2个以上的新表格)，则第二字段可以有多个比特位，用于指示一张或多张BS表格的索引号，例如每2个比特表示一张BS表格的索引号。可选的，第二字段能够指示的BS表格数量与第一字段能够指示的剩余时间区间数量或MAC CE中存在的BS value字段的个数相关。
(三)BS value字段指示第一逻辑资源中待传输数据的数据量大小所属的第一BS区间，可能包括如下几种情况：
情况①、BS value字段的数量为1个，BS value字段用于指示第一逻辑资源中所有待传输数据的总数据量大小所属的第一BS区间。也就是说，MAC CE中只存在一个BS value字段，用于指示第一逻辑资源中总的待传输数据量。
举例来说，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为500Bytes，待传输数据2的数据量大小为1000Bytes，待传输数据3的数据量大小为2000Bytes，如果是情况①，且采用表2(即旧表格)，那么BS value字段的取值为“01011110(94)”，即(3469,3694]。
又假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为150Bytes，待传输数据2的数据量大小为300Bytes，待传输数据3的数据量大小为100Bytes，如果是情况①，且采用表2(即旧表格)，那么BS value字段的取值为“01000000(64)”，即(526,560]。
情况②、BS value字段的数量为1个，BS value字段用于指示至少一份待传输数据对应的剩余时间中的最小剩余时间内的待传输数据的数据量大小所属的第一BS区间。也就是说，当第一字段指示了最小剩余时间或最小剩余时间区间时，MAC CE中只存在一个BS value字段，用于指示第一逻辑资源中剩余时间最少或在最小剩余时间区间内的待传输数据量。
举例来说，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为500Bytes且剩余时间为3ms，待传输数据2的数据量大小为1000Bytes且剩余时间为7ms，待传输数据3的数据量大小为2000Bytes且剩余时间为9ms。如果是情况②，且采用表2(即旧表格)，那么BS value字段的取值为“00111111(63)”，即(494,526]。
又假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为150Bytes且剩余时间为3ms，待传输数据2的数据量大小为300Bytes且剩余时间为8ms，待传输数据3的数据量大小为100Bytes且剩余时间为18ms，如果是情况②，且采用表2(即旧表格)，那么BS value字段的取值为“00101011(43)”，即(141,150]。
情况③、BS value字段的数量为2个，其中一个BS value字段用于指示总数据量大小所属的第一BS区间，另一个BS value字段用于指示最小剩余时间内的待传输数据的数据量大小所属的第一BS区间。也就是说，当第一字段指示了最小剩余时间或最小剩余时间区间时，MAC CE中存在两个BS value字段，其中一个指示第一逻辑资源中剩余时间最少或在最小剩余时间区间内的待传输数据量，另一个指示第一逻辑资源中除上述最小剩余时间区间内的数据量之外的待传输数据量，或者，指示第一逻辑资源中总的待传输数据量。可理解的，本申请实施例中最小剩余时间区间内的待传输数据量+除最小剩余时间区间内的数据量之外的待传输数据量＝第一逻辑资源中所有待传输数据的总数据量大小。
举例来说，假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为500Bytes且剩余时间为3ms，待传输数据2的数据量大小为1000Bytes且剩余时间为7ms，待传输数据3的数据量大小为2000Bytes且剩余时间为9ms。如果是情况③，且采用表2(即旧表格)，那么一个BS value字段(即最小剩余时间内的待传输数据的数据量大小所属的第一BS区间)的取值为“00111111(63)”，即(494,526]；另一个BS value字段(即指示总数据量大小所属的第一BS区间)的取值为“01011110(94)”，即(3469,3694]。
又假设第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为150Bytes且剩余时间为3ms，待传输数据2的数据量大小为300Bytes且剩余时间为8ms，待传输数据3的数据量大小为100Bytes且剩余时间为18ms。如果是情况③，且采用表2(即旧表格)，那么一个BS value字段(即最小剩余时间内的待传输数据的数据量大小所属的第一BS区间)的取值为“00101011(43)”，即(141,150]；另一个BS value字段(即指示总数据量大小所属的第一BS区间)的取值为“01000000(64)”，即(526,560]。
情况④、BS value字段的数量等于第一字段指示的剩余时间区间的个数，一个BS value字段对应第一字段指示的剩余时间区间中的一个剩余时间区间，一个BS value字段用于指示第一逻辑资源中剩余时间在一个剩余时间区间内的待传输数据的数据量大小所属的第一BS区间。也就是说，当第一字段指示了多个剩余时间区间(即第一字段为情况3)时，MAC CE中存在一个或多个BS value字段，BS value字段的个数取决于第一字段中取值为“1”的比特个数，每个BS value字段对应一个剩余时间区间，表示第一逻辑资源中剩余时间在该剩余时间区间范围内的待传输数据量所属的第一BS区间。
举例来说，假设第一字段包含2bit，通过预定义或预配置的方式事先约定其中低位比特代表了剩余时 间区间0～10ms，高位比特代表了剩余时间区间10～20ms；第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为500Bytes且剩余时间为3ms，待传输数据2的数据量大小为1000Bytes且剩余时间为7ms，待传输数据3的数据量大小为2000Bytes且剩余时间为9ms，因此，第一字段可以为“01”，表示第一逻辑资源中存在剩余时间在0～10ms范围内的数据，而不存在剩余时间在10～20ms范围内的数据。由于第一字段中取值为“1”的比特个数为1个，因此可确定BS value字段的个数也为1个，且该1个BS value字段的取值为“01011110(94)”，即表示第一逻辑资源中剩余时间在0～10ms范围内的待传输数据量所属的第一BS区间为(3469,3694]。
举例来说，假设第一字段包含2bit，通过预定义或预配置的方式事先约定其中低位比特代表了剩余时间区间0～10ms，高位比特代表了剩余时间区间10～20ms；第一逻辑资源中包括3份待传输数据(待传输数据1，待传输数据2和待传输数据3)，其中，待传输数据1的数据量大小为150Bytes且剩余时间为3ms，待传输数据2的数据量大小为300Bytes且剩余时间为8ms，待传输数据3的数据量大小为100Bytes且剩余时间为18ms，因此，第一字段可以为“11”，表示第一逻辑资源中既存在剩余时间在0～10ms范围内的数据，又存在剩余时间在10～20ms范围内的数据。由于第一字段中取值为“1”的比特个数为2个，因此可确定BS value字段的个数也为2个，且该2个BS value字段中一个BS value字段的取值为“00111101(61)”，表示第一逻辑资源中剩余时间在0～10ms范围内的待传输数据量所属的第一BS区间为(436,464]；另一个BS value字段的取值为“00100101(37)”，即表示第一逻辑资源中剩余时间在10～20ms范围内的待传输数据量所属的第一BS区间为(96,103]。
为了更好的帮助理解实现方式1，这里以上面提到的部分可能形式为例，给出几种具体取值的例子来对MAC CE所表达的含义加以说明：
例子一：第一字段长度4bit，用于显式指示LCG x数据的最小剩余时间；第二字段长度1bit，用于指示BS value字段参考的BS表格；仅存在一个BS value字段，表示LCG x总的待传输数据量。第一字段取值“1010”，第二字段取值“1”，BS value取值“01000000(64)”。
a)假设LCG x同时配置了新BS表格和剩余时间上报的功能，则第一字段表示LCG x中数据的最小剩余时间为10ms，第二字段表示BS value参考新的BS表格，BS value指示了索引64，则在新定义的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量；
b)假设LCG x配置了新BS表格，但没有配置剩余时间上报的功能，则第一字段无意义，根据第二字段和BS value，在新定义的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量；
c)假设LCG x未配置新的BS表格，但配置了剩余时间上报的功能，则第一字段表示LCG x中数据的最小剩余时间为10ms，第二字段无意义，BS value默认仍参考旧的BS表格，在旧的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量；
d)假设LCG x既没有配置新的BS表格，也没有配置剩余时间上报的功能，则在旧的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量。
例子二：第一字段长度2bit，其中低位比特代表剩余时间区间0～10ms，高位比特代表10～20ms；第二字段长度2bit，分别对应第一字段的两个时间区间；BS value字段的个数与第一字段有关，第一字段无意义时只有一个BS value字段，第一字段有意义时BS value字段的个数与第一字段中取值为“1”的比特个数相等。第一字段取值“01”，第二字段取值“11”，BS value取值“01000000(64)”。
a)假设LCG x同时配置了新BS表格和剩余时间上报的功能，则第一字段表示LCG x中存在剩余时间在0～10ms的数据且不存在剩余时间在10～20ms的数据；第二字段低位比特表示剩余时间0～10ms的数据对应的BS value参考新的BS表格，高位比特无意义；BS value指示了索引64，则在新定义的BS表格中查找到索引号64对应的数据量即为LCG x中剩余时间为0～10ms的待传输数据量；
b)假设LCG x配置了新BS表格，但没有配置剩余时间上报的功能，则第一字段无意义，根据第二字段和BS value，在新定义的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量；
c)假设LCG x未配置新的BS表格，但配置了剩余时间上报的功能，则第一字段表示LCG x中存在剩余时间在0～10ms的数据且不存在剩余时间在10～20ms的数据；第二字段无意义，BS value默认仍参考旧的BS表格，在旧的BS表格中查找到索引号64对应的数据量即为LCG x中剩余时间为0～10ms的待传输数据量；
d)假设LCG x既没有配置新的BS表格，也没有配置剩余时间上报的功能，则在旧的BS表格中查找到索引号64对应的数据量即为LCG x中总的待传输数据量。
除此之外，为了更好的帮助理解实现方式2，这里以上面提到的部分可能形式为例，给出几种具体取值的例子来对MAC CE所表达的含义加以说明：
例子一：第三字段取值“1”，第四字段取值“0”，此时MAC CE中有第一字段但没有第二字段。假设第一字段长度2bit，其中低位比特代表剩余时间区间0～10ms，高位比特代表10～20ms；BS value字段的个数与第一字段中取值为“1”的比特个数相等。第一字段取值“01”，BS value取值“01000000(64)”，则表示LCH x中存在剩余时间0～10ms的待传输数据且不存在剩余时间10～20ms的数据。BS value默认仍参考旧的BS表格，在旧的BS表格中查找到索引号64对应的数据量即为LCH x中剩余时间为0～10ms的待传输数据量；
例子二：第三字段取值“0”，第四字段取值“1”，此时MAC CE中有第二字段但没有第一字段。假设第二字段长度1bit，BS value字段只有一个。第一字段取值为“1”，BS value取值为“01000000(64)”，则表示在新的BS表格中查找到索引号64对应的数据量即为LCH x中总的待传输数据量；
例子三：第三字段取值“1”，第四字段取值“1”，此时MAC CE中既有第一字段，也有第二字段。假设第一字段长度2bit，其中低位比特代表剩余时间区间0～10ms，高位比特代表10～20ms；第二字段长度2bit，分别对应第一字段的两个剩余时间区间；BS value字段的个数与第一字段中取值为“1”的比特个数相等。第一字段取值“01”，第二字段取值“11”，BS value取值“01000000(64)”。则第一字段表示LCH x中存在剩余时间0～10ms的待传输数据且不存在剩余时间10～20ms的数据。第二字段低位比特表示0～10ms区间的BS value参考新表格，高位比特无意义。在新的BS表格中查找到索引号64对应的数据量即为LCH x中剩余时间为0～10ms的待传输数据量。
S402、终端设备向接入网设备发送上行信号。相应地，接入网设备接收来自终端设备的上行信号。
在一些可行的实施方式中，当接入网设备接收来自终端设备的上行信号之后，接入网设备可以根据接收到的上行信号中携带的至少一个逻辑资源的信息，确定至少一个逻辑资源中每个逻辑资源中待传输数据的剩余时间信息，每个逻辑资源启用的第一BS表格，以及每个逻辑资源中待传输数据的数据量大小所属的第一BS区间等中的一项或者多项信息。因此，接入网设备可以基于获取到的信息及时调度数据，避免超时。
