具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***或5G***等。
示例性的，本申请实施例应用的通信***100如图1所示。该通信***100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备110可以是GSM***或CDMA***中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信***(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上 型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、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、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G***或5G网络还可以称为新无线(New Radio，NR)***或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/***中具有通信功能的设备可称为通信设备。以图1示出的通信***100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信***100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种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。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在终端设备与网络设备之间的通信过程中，网络设备可以针对终端设备分配授权，分配的授权可以包括配置授权(Configured Grant)和/或动态授权。其中，配置授权可以是网络设备半静态配置给终端设备的，动态授权可以是网络设备动态调度给终端设备的，例如，可以通过下行控制信息(Downlink Control Information，DCI)调度给终端设备的。每个授权可以对应于一个资源，用于传输MAC PDU。在本申请实施例中，也可以将授权理解为资源。
在终端设备侧，可能存在多个授权的资源冲突的情况。其中，多个授权的资源冲突可以是指多个授权所占用的资源完全相同，或者，也可以是多个授权所占用的资源部分重叠。
在终端设备的多个授权存在资源冲突的情况下，该终端设备将会执行针对其中的一个授权的传输。
例如，如图2所示，DCI1和DCI2分别为终端设备分配了授权1和授权2，该授权1和授权2具有重叠的资源，其中，针对授权1的MAC PDU1的组包的时间早于针对授权2的MAC PDU2的组包的时间(此时，授权1在时域上所占用的起始位置可以早于授权2在时域上所占用的时域位置，和/或，授权1的时域长度可以长于授权2的时域长度)，如果授权2的业务的优先级高于授权1的业务的优先级，则将会在授权2上传输MAC PDU2，MAC PDU1将会被丢弃或等待后续的授权进行传输。
在终端设备侧，当新上行数据到来(也即新的上行数据产生)时，在MAC层，可以触发生成BSR，该BSR可以用来生成MAC CE，该MAC CE可以封装在MAC PDU中。
例如，如图2所示，在组包MAC PDU1之前，因新上行数据到来而触发了BSR1，该BSR1的MAC CE可以封装在MAC PDU1中，在MAC PDU1组包时，可以将该BSR1取消。
以及如图2所示，可以针对授权2封装MAC PDU2，由于授权2的业务的优先级相比于授权1的业务的优先级更高，此时，终端设备可以在授权2上传输MAC PDU2，且放弃MAC PDU1或缓存MAC PDU1以用于后续传输。
该种实现方式可以保障优先级高的业务能够及时传输，但是如果BSR的MAC CE被封装到了优先级低的业务的MAC PDU上，如该BSR封装到了上文所述的MAC PDU1中,而未封装到MAC PDU2中，则会导致该BSR不能被上报给网络侧。
基于此，本申请实施例提供了以下的方案，可以避免被触发的报告例如BSR不能被上报给网络侧的问题，从而提高通信性能。
图3是根据本申请实施例的通信方法200的示意性流程图。该方法200包括以下内容中的至少部分内容。
在210中，在第一上行信道资源上传输第一MAC PDU时，终端设备取消第一报告，所述第一报告用于生成所述第一MAC PDU中包含的第一MAC CE。
具体地，终端设备可以基于第一报告生成第一MAC CE，并可以将该第一MAC CE封装到第一MAC PDU中，并在该第一上行信道资源上传输该第一MAC PDU，在该第一上行信道资源上传输第一MAC PDU时，终端设备可以取消第一报告。
其中，取消第一报告的时间可以是从传输第一MAC PDU的起始点开始执行的，或者，也可以在传输第一MAC PDU的中间时间点开始执行，或者，也可以在结束传输第一MAC PDU的时间点开始执行。
可选地，本申请实施例中的上行信道资源(例如，第一上行信道资源和第二上行信道资源)可以是物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。
可选地，本申请实施例中提到的报告(可以是上文提到的第一报告，下文提到的第二报告和第三报告)可以是MAC层触发的报告。本申请实施例中的报告具体可以为BSR、功率余量报告(Power Headroom Report，PHR)或配置授权确认。
可选地，本申请实施例中的BSR可以分为重传BSR、周期性BSR、填充BSR(padding BSR)、长BSR(long BSR)、短BSR(short BSR)或截断BSR(Truncated BSR)。其中，截断BSR还可以进一步划分为短截断BSR(Short Truncated BSR)或长截断BSR(Long Truncated BSR)。
可选地，本申请实施例中的PHR可以为周期性PHR。
可选地，本申请实施例中的配置授权确认可以是针对网络设备向终端设备配置授权、激活授权或去激活授权进行确认的报告。
可选地，本申请实施例中的报告可以是周期性触发的报告，也可以是因特殊事件而被触发的报告。
以报告为BSR为例，BSR可以是周期性触发的报告，或者，也可以是因上行数据到达而触发的报告。
本申请实施例中的MAC PDU可以包括多个MAC子PDU，MAC子PDU可以包括服务数据单元(Serving Data Unit，SDU)和其子头，或者可以包括MAC CE和其子头，其中，MAC CE可以是固定大小的MAC CE，也可以是可变长度的MAC CE，例如，如图4所示。
以及如图5所示，MAC CE的子头可以包括逻辑信道标识(Logic Channel Identity，LCID)，其中，此处的LCID用于区分该MAC CE对应的报告是哪种类型的报告，例如，是长BSR、短BSR还是PHR等。其中，图5中的R代表预留比特，L代表对应MAC CE占用的字节长度，F代表(MAC CE的)长度域的大小，
如图6和7所示，MAC CE中可以包括逻辑信道组(Logic Channel Group，LCG)标识(Identity，ID)及其该逻辑信道组的缓存大小，其中，图6所示的是短BSR或短截断BSR的MAC CE的格式，也即具有一个逻辑信道组的标识及其缓存大小；图7所示的是长BSR或长截断BSR的MAC CE的格式，也即具有多个逻辑信道组的标识及其缓存 大小。
可选地，本申请实施例中的报告可以是基于逻辑信道(Logic Channel，LC)或逻辑信道组触发的报告，也可以称为per逻辑信道或逻辑信道组的报告。
可选地，在本申请实施例中，逻辑信道或逻辑信道组可以对应于业务，例如，一个业务可以对应于至少一个逻辑信道或逻辑信道组，不同的业务可以对应的逻辑信道或逻辑信道组可以完全不同。
在本申请实施例中，一个逻辑信道组中的所有逻辑信道可以对应于同一业务，也可以对应于不同的业务。
本申请实施例中的逻辑信道的类别可以是依据所对应的业务进行划分，例如，对应相同业务的逻辑信道(此处的逻辑信道可以是逻辑信道组)可以是同类逻辑信道，或者包含相同业务的逻辑信道组可以是同类逻辑信道组，或者逻辑信道的类别也可以是基于所属的逻辑信道组进行划分的，例如，属于相同逻辑信道组的逻辑信道可以是同类逻辑信道。
其中，报告是基于逻辑信道或逻辑信道组触发的报告可以理解为：报告是基于业务触发的报告，此时此处提到的逻辑信道或逻辑信道组是该业务对应的逻辑信道或逻辑信道组。基于业务触发的也可以称为报告是per业务的。
可选地，报告中携带的信息是基于业务的信息，该业务是某一逻辑信道或逻辑信道组的业务，则该报告所属的逻辑信道或逻辑信道即为该某一逻辑信道或逻辑信道组。
可选地，在本申请实施例中，报告的MAC CE中可以携带所基于的逻辑信道的标识(Logic Channel Identity，LCID)。
例如，如图8和9所示，MAC CE中可以携带报告所属的逻辑信道的标识。其中，图8所示的为在MAC CE中封装了一个逻辑信道的缓存大小的信息。图9所示的在MAC CE中封装了多个逻辑信道的缓存大小的信息。其中，图9中的多个逻辑信道可以是一类逻辑信道，例如，可以对应于相同的业务。
图9所示的是8个逻辑信道的缓存大小的信息，如果业务的逻辑信道数量小于8个或者存在少于8个的逻辑信道具有缓存的数据，则可以MAC CE中携带少于8的逻辑信道的标识和其缓存大小。此时，MAC CE的大小可变。
例如，如图10所示，可以携带5个逻辑信道的标识及其缓存大小，其他比特位置可以为预留比特位R。
或者，在本申请实施例中，在报告是基于业务触发时，一个业务可能对应于至少一个逻辑信道组，则可以在MAC CE中携带该至少一个逻辑信道组的标识信息及其缓存大小。
例如，如图11所示，业务对应的逻辑信道组可以是4个，则可以在MAC CE中携带4个逻辑信道组的标识及其缓存大小，其他比特可以是预留比特。
可选地，在本申请实施例中，所述第一报告是第一逻辑信道的报告，在用于触发所述第一逻辑信道的报告的条件得到满足时，所述第一报告被触发。
其中，所述用于触发所述第一逻辑信道的报告的条件包括以下中的至少一种：
1)所述第一逻辑信道或所述第一逻辑信道所属的逻辑信道组存在待传输的数据。
2)所述第一逻辑信道存在待传输的数据，以及所述第一逻辑信道所属的逻辑信道组中除所述第一逻辑信道之外的逻辑信道没有待传输的数据。
3)所述第一逻辑信道存在待传输的数据，以及所述第一逻辑信道所属的逻辑信道组中的第四逻辑信道具有待传输的数据，所述第四逻辑信道的优先级低于所述第一逻辑信道的优先级。
4)所述第一上行信道资源被分配用于传输所述第一逻辑信道或第一逻辑信道所属的逻辑信道组的数据。
5)所述第一上行资源信道资源中传输数据之后剩余比特的数量大于或等于第一数 值，所述第一数值为所述第一MAC CE和所述第一MAC CE的子头所占用的比特数量。
6)所述第一逻辑信道或所述第一逻辑信道所属的逻辑信道组的重传报告定时器超时。
7)所述第一逻辑信道或所述第一逻辑信道所属的逻辑信道组的周期报告定时器超时。
可选地，在本申请实施例中，所述第一报告的逻辑信道与第一授权承载的数据所属的逻辑信道为同一逻辑信道或同类逻辑信道，或者说，所述第一授权能够满足为所述第一报告的逻辑信道配置的逻辑信道优先级映射限制，所述第一授权是对应所述第一MAC PDU的授权。
具体地，在某一类逻辑信道或某一逻辑信道的授权封装MAC PDU时，可以将该类逻辑信道该逻辑信道的报告封装到MAC PDU中。
其中，逻辑信道或逻辑信道组的逻辑信道优先级映射限制可以表示利用授权传输逻辑信道或逻辑信道组中的信息时，对授权的要求或限制，如果授权满足该要求或限制时，则该授权上可以传输该逻辑信道或逻辑信道组中的数据或信息。
因此，本申请实施例提到的将第一报告通过与该第一报告具有相同的逻辑信道或同类逻辑信道MAC PDU上报给网络侧，即可以理解为：将第一报告通过与该第一报告具有相同业务的MAC PDU上报给网络侧。
本申请实施例提到的所述第一授权能够满足为所述第一报告关联的逻辑信道或逻辑信道组配置的逻辑信道优先级映射限制，即可以理解为：所述第一报告的逻辑信道或逻辑信道组的逻辑信道优先级映射限制与第一授权(具体可以是第一授权的属性)相匹配。
可选地，在本申请实施例中，在所述第一上行信道资源上传输所述第一MAC PDU时或在传输所述第一MAC PDU之前，终端设备取消第二报告，所述第二报告是在对所述第一MAC PDU组包与在所述第一上行信道资源上传输所述第一MAC PDU之间被触发的。
具体地，由于第一MAC PDU组包之后与第一MAC PDU传输之前触发了第二报告，相比于第一报告，该第二报告可能是一些与第一报告的信息内容重复的报告或包含了无用信息的报告，例如，第二报告是重传BSR、周期性BSR或填充BSR，则可以取消第二报告，具体可以在第一上行信道资源上传输第一MAC PDU时取消第二报告，或者，由于第二报告是相对无用的报告，也可以在第一MAC PDU传输之前取消第二报告，当然，也可以在传输第一MAC PDU之后取消第二报告，本申请实施例对此不进行限定。
其中，所述第二报告可选地为满足以下条件的报告：与所述第一报告具有同类逻辑信道或同一逻辑信道。其中，第一报告与第二报告具有同类逻辑信道或同一逻辑信道可以是指第一报告与第二报告所属的业务相同，或者可以指第一报告与第二报告具有同类逻辑信道或同一逻辑信道中的信息，或者可以指第一报告与第二报告具有同类逻辑信道组或同一逻辑信道组中的信息。
具体地，第一报告与第二报告具有同类逻辑信道或同一逻辑信道，则第二报告相对于第一报告而言，通常是包含了一些重复的信息，则此时，可以取消第一报告。
其中，第一报告与第二报告具有同类逻辑信道或同一逻辑信道可以理解第一报告和第二报告分别是相同业务的报告。
在本申请实施例中，第一报告具有的逻辑信道或逻辑信道组可以称为：第一报告所属的逻辑信道或逻辑信道组，第一报告的逻辑信道或逻辑信道组，或所述第一报告关联的逻辑信道或逻辑信道组。
可选地，在本申请实施例中，报告关联于逻辑信道组，可以是指报告包括该逻辑信道中的信息。以及，报告关联于逻辑信道组，可以是指报告包括该逻辑信道组中的全部或部分的逻辑信道中的信息。
或者，在本申请实施例中，报告关联于逻辑信道组，可以是指报告包括该逻辑信道 对应的业务的信息。以及，报告关联于逻辑信道组，可以是指报告包括该逻辑信道组中的全部或部分的逻辑信道对应的业务的信息。
本申请实施例中提到的业务可以是增强型移动带宽(enhanced Mobile Broad Band,eMBB)业务、海量机器类通信(massive Machine-Type Communications，mMTC)业务、超高可靠低时延(ultra-Reliable Low latency Communications，uRLLC)业务、工业物联网(Industrial Internet of Things,IIoT)业务。
可选地，在本申请实施例中，终端设备可以保留第三报告，直到在第二上行信道资源上传输第二MAC PDU，所述第二MAC PDU中包含基于所述第三报告生成的第二MAC CE；所述第三报告是在对所述第一MAC PDU组包与在所述第一上行信道资源上传输所述第一MAC PDU之间被触发的。
具体地，在对第一MAC PDU组包与在第一上行信道资源上传输第一MAC PDU之间触发了第三报告，也可以保留该第三报告直到在第二上行信道资源上传输了封装有该第三报告的MAC CE的第二MAC PDU。
其中，在第三报告是满足以下条件中的至少一个的报告时，第三报告可以不被取消：
因上行数据到达而被触发；
具有非第一逻辑信道的第二逻辑信道，或，具有与所述第一逻辑信道不同类的第三逻辑信道，所述第一逻辑信道是所述第一报告所属的逻辑信道。
具体地，如果第三报告是因上行数据到达而被触发的，则第三报告的信息对于终端设备而言是相对比较有用的，终端设备可以通过将该BSR上报给网络设备，而实现向网络设备请求授权。
以及如果第一报告与第三报告具有不同的逻辑信道或不同类的逻辑信道，则代表该第三报告是其它业务触发的报告，则第三报告即不是第一报告的重复，从而需要将该第三报告上报到网络侧。
可选地，在本申请实施例中，所述第一上行信道资源配置用于传输第一授权和第二授权的MAC PDU；所述第一授权的MAC PDU是所述第一MAC PDU；所述第二授权的MAC PDU是第三MAC PDU，所述第三MAC PDU是在所述第一MAC PDU之前进行组包且未在所述第一上行信道资源上被发送，所述第三MAC PDU包含所述第一MAC CE。
具体地，正如上文提到，在多个授权的资源存在资源冲突的情况下，则终端设备可以择一个授权的第一MAC PDU在冲突的资源上进行传输，即使第一MAC PDU之前存在第二授权的第三MAC PDU封装了第一报告，由于第一报告未被取消，则可以基于第一报告生成MAC CE，以封装到第一MAC PDU中，从而可以实现即使在前的第三MAC PDU未被传输，仍然可以将第一报告通过第一MAC PDU上报给网络侧。
本申请实施例中提到的授权可以是配置的授权或动态的授权，其中，配置的授权可以是网络设备半静态配置的，例如，可以是通过RRC信令配置的，动态的授权可以是网络设备通过DCI向终端设备调度的。
为例更加清楚地理解本申请，以下将以第一报告为BSR为例，结合图1对本申请实施例进行描述。
如图2所示，DCI1和DCI2分别为终端设备分配了授权1和授权2，授权1的资源和授权2的资源可以具有重叠的资源，假设授权2的优先级高于授权1的优先级。
当满足一定条件时，例如，因新上行数据到达时，BSR1将会被触发，基于BSR1生成的BSR MAC CE将会被封装到MAC PDU 1，MAC PDU1是针对授权1的MAC PDU。
假设授权1的优先级高于授权2的优先级，终端设备可以在授权1上传输包含BSR MAC CE的MAC PDU1，并在传输该MAC PDU1时，可以取消BSR，其中，由于针对授权2的MAC PDU2将不会被传输，则可以无需将BSR的MAC CE封装到MAC PDU2，或者也可以不生成MAC PDU2。
假设授权2的优先级高于授权1的优先级，由于该BSR1一直未被取消，则可以基 于该BSR1生成MAC CE，并将该MAC CE封装到MAC PDU2，在授权2上传输包含BSR1的MAC CE的MAC PDU2，以及在传输MAC PDU2时，取消该BSR。
假设在MAC PDU1组包之后与在授权1上传输MAC PDU(MAC PDU1或MAC PDU2)之前存在新的BSR2，可以在授权1上传输数据时将新的BSR进行取消，也可以不取消。
例如，在该BSR2是重传BSR、周期性BSR或是填充BSR，则可以取消该BSR2。
例如，在该BSR2是因新上行数据到达时触发的BSR，则不取消该BSR2，等待为下一个授权封装MAC PDU3时，基于该BSR2生成MAC CE，将该MAC CE封装到MAC PDU3上。
应理解，在本申请实施例中，在BSR2是因新上行数据到达时，如果BSR2是在MAC PDU1组包之后与MAC PDU2组包之前触发的，且在授权2上传输MAC PDU2，则可以将该BSR2的MAC CE与BSR1的MAC CE一同封装到MAC PDU2中，或者将两个中的至少之一封装到MAC PDU2，或者将BSR2的MAC CE封装到MAC PDU2。
如果资源1在传输了上行数据的剩余比特不足以同时封装BSR1的MAC CE及其子头和BSR2的MAC CE及其子头，则可以仅封装BSR1的MAC CE及其子头，或仅封装BSR2的MAC CE及其子头，具体封装哪个BSR的MAC CE及其子头，可以根据BSR的优先级而定，BSR的优先级可以基于该BSR所属逻辑信道或逻辑信道组的优先级而定。或者，可以封装在前的BSR的MAC CE，也即封装BSR1的MAC CE在MAC PDU2中。或者，可以封装在后的BSR的MAC CE，也即封装BSR2的MAC CE在MAC PDU2中。BSR1和BSR2中未被封装对应的MAC CE可以封装到下一个授权的MAC PDU3。
以上以两个授权的资源重叠为例进行说明，但应理解，本申请实施例也适用于多于两个授权的资源重叠的场景。
以上描述了在授权的资源重叠时，如何取消报告的方案，以下将介绍在授权的资源不重叠的情况下，如何进行报告的取消。
如图12所示，网络设备通过DCI1和DCI2分别为终端设备分配了授权1和授权2，授权1的资源1和授权2的资源2是非重叠的资源。由于授权1和授权2不存在重叠的资源，则可以分别在资源1发送针对授权1封装的MAC PDU1，以及在资源2上发送针对授权2封装的MAC PDU2。
当满足一定条件时，例如，因新上行数据到达时，BSR1将会被触发，基于BSR1生成的MAC CE将会封装到MAC PDU1中，在授权1的资源1上传输MAC PDU1，并在传输MAC PDU1时，将BSR1进行取消。
假设在MAC PDU1组包之后MAC PDU2组包之前没有新的BSR，MAC PDU2中可以不包含BSR的MAC CE。
或者即使在MAC PDU1组包之后MAC PDU2组包之前有新的BSR，如果新的BSR是周期性的BSR，重传BSR或者填充BSR,则可以不在MAC PDU2中封装该新的BSR。其中，这些新的BSR可以在被触发时即被取消，或者也可以在资源1上传输MAC PDU1时被取消。
如果如图13所示，在MAC PDU1组包1之后和MAC PDU2组包之前触发了BSR2，该BSR2是因新上行数据到达而被触发的，则可以在MAC PDU2中封装该BSR2的MAC CE，并且在资源2上传输MAC PDU2时，取消该BSR2。
在本申请实施例中，以上提到了报告可以是基于逻辑信道触发的，也即报告可以是per逻辑信道或per业务的，这些报告的取消方式可以不限于以上提到的在传输封装了该报告的MAC CE的MAC PDU时取消，例如，可以在封装该MAC PDU时取消，也可以在封装该MAC PDU之后以及传输该MAC PDU之前取消。
在本申请实施例中，在传输第一MAC PDU时，将用于生成所述第一MAC PDU中包含的第一MAC CE的第一报告进行取消，而非生成该MAC PDU时，将该第一报告取 消，从而可以避免第一MAC PDU未被传输所带来的第一报告不能上报给网络侧的问题。
具体地，在第一报告是BSR时，可以将终端设备的传输需求及时上报给网络侧，从而使得网络设备侧可以及时对终端设备的调度，特别是BSR是基于特定业务(例如，URLLC业务)的BSR时，可以使得该保证该业务的QoS。
应理解，上述方法200仅仅是本申请的具体实现方式，本申请实施例还可以具有其他的实现方式。
例如，以上提到在第一上行信道资源上传输第一MAC PDU时，终端设备取消第一报告，所述第一报告用于生成所述第一MAC PDU中包含的第一MAC CE，在本申请实施例中，如果终端设备确定到第一上行信道资源上不存在除第一MAC PDU的授权之外的授权，则可以在确定到这一事实时，即取消第一报告，例如，终端设备在封装第一MAC PDU时或之前，确定到第一上行信道资源上不存在除第一MAC PDU的授权之外的授权，则可以在封装第一MAC PDU时即取消第一报告；例如，终端设备在封装第一MAC PDU之后，确定到第一上行信道资源上不存在除第一MAC PDU的授权之外的授权，则可以在确定到第一上行信道资源上不存在除第一MAC PDU的授权之外的授权时，即取消第一报告。
或者，在本申请实施例中，即使第一上行信道用于多个授权，该多个授权包括第一MAC PDU的授权，如果终端设备确定第一MAC PDU的授权的优先级最高，则终端设备可以在确定到第一MAC PDU的授权的优先级最高时，取消第一报告；如果终端设备先确定到第一MAC PDU的授权的优先级最高，后进行第一MAC PDU的封装，则可以在进行第一MAC PDU的封装时取消第一报告。
图14是根据本申请实施例的终端设备400的示意性框图。该终端设备400包括取消单元410，用于：

可选地，在本申请实施例中，所述第一报告是属于第一逻辑信道的报告，在用于触发所述第一逻辑信道的报告的条件得到满足时，所述第一报告被触发。
