Description

媒体接入控制MAC重置定时器的处理方法及装置 技术领域
本公开涉及移动通信技术领域，特别涉及一种媒体接入控制MAC重置定时器的处理方法及装置。
背景技术
混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)协议是新空口(New Radio，NR)中最主要的重传方式。当数据包译码错误时，会发送重传请求。尽管无法解析数据包，但接收到的数据包中仍包含有用信息，因此，如果丢弃错误的数据包，会导致有用信息丢失。现有机制将接收到的错误数据包存储在HARQ buffer中，随后与重传的数据包进行合并，得到一个合并的数据包，并对合并的数据包进行纠错解码。由于初传和重传一般采用相同的方式进行调度，终端需要知道这次传输是新传还是重传，因为新传需要清空缓存，而重传需要进行合并，因此下行发送的调度信息中包含了一个显式的新数据指示(New data indicator,NDI)，用于标记该调度的传输块(Transport Block,TB)。NDI本质上是一个1bit的序列号，在新传输块时会翻转，当接收到一个下行调度分配时，终端会检查NDI，判断当前传输是应该与HARQ buffer中的数据包进行合并还是清空HARQ buffer。
在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)R18标准中研究支持非激活态组播业务接收，当终端从非激活态时，也能够继续执行组播业务数据接收。在现有机制中，当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程。在MAC重置流程中，所有定时器会被停止或被视为到期，同时会清空HARQ buffer以及每个下行HARQ链路的配置。从而使支持非激活态组播业务接收的终端，无法继续接收非激活态组播业务(Multicast Broadcast Service，MBS)的业务数据，或产生数据丢失。

具体实施方式
下面详细描述本公开的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)协议是新空口(New Radio，NR)中最主要的重传方式。当数据包译码错误时，会发送重传请求。尽管无法解析数据包，但接收到的数据包中仍包含有用信息，因此，如果丢弃错误的数据包，会导致有用信息丢失。现有机制将接收到的错误数据包存储在HARQ buffer中，随后与重传的数据包进行合并，得到一个合并的数据包，并对合并的数据包进行纠错解码。
然而对于释放到非激活态的终端，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有定时器会被停止或被视为到期。在此种初始化操作下，组播业务无法正常接收，且会继续执行后续清空HARQ buffer以及下行HARQ链路配置的操作。而对于非激活态组播业务来说，不能清空HARQ buffer，一旦清空HARQ buffer，则在非激活态组播业务数据传输过程中发生数据包译码错误时，不能在HARQ buffer中查取译码错误的数据包，进而容易导致有用信息丢失或直接导 致译码失败。
为此，本公开提出了一种媒体接入控制MAC重置定时器的处理方法及装置，可支持非激活态组播业务接收并降低数据丢失。
下面结合附图对本申请所提供的切换方法及装置进行详细地介绍。
图1示出了根据本公开实施例的一种媒体接入控制MAC重置定时器的处理方法的流程示意图。如图1所示，该方法应用于终端，且可以包括以下步骤。
步骤101、对于非激活态组播业务MBS，在媒体接入控制MAC重置过程中，终端根据协议约定对MBS相关定时器执行控制操作。
其中，非激活态组播业务(Multicast Broadcast Service，MBS)为非激活态终端仍能执行业务数据接收的组播业务。
当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有定时器会被停止。在此种初始化操作下，对于非激活态组播业务这一下行配置业务来说，将会无法接收组播业务的业务数据，导致组播业务无法正常执行。故为了保证终端针对非激活态组播业务MBS的正常执行，在媒体接入控制MAC重置过程中，终端根据协议约定对定时器执行不停止MBS相关定时器的操作，可保证支持非激活态组播业务接收的终端，能够正常接收到非激活态组播业务。
在本公开的实施例中，对MBS相关定时器执行控制操作，可包括两种可能实现的方式：
作为一种可能实现方式：对于非激活态组播业务MBS，在媒体接入控制MAC重置过程中，终端可根据协议约定执行不停止MBS相关定时器的操作。在该操作中，终端可以继续运行MBS相关定时器；或者，终端可以停止除了MBS相关定时器之外的所有定时器。
作为一种可能实现方式：对于非激活态组播业务MBS，在媒体接入控制MAC重置过程中，终端可根据协议约定执行停止MBS相关定时器，并之后重新启动MBS相关定时器的操作。在该重新启动操作中，包括但不限于以下任意一种情况：
终端立刻重启MBS相关定时器；
终端在满足MBS相关定时器开启条件时重启MBS相关定时器；
终端在指定时刻重启MBS相关定时器，其中，指定时刻为根据协议约定或网络配置确定的。
在本公开的实施例步骤中，MBS相关定时器至少包括非连续性接收(Discontinuous Reception,DRX)配置相关定时器，DRX配置相关定时器包括但不限于以下至少一项：
用于点对多点传输PTM的DRX激活态定时器(drx-onDurationTimerPTM)；
用于点对多点传输PTM的DRX非激活态定时器(drx-InactivityTimerPTM)；
用于点对多点传输PTM的DRX下行重传定时器(drx-RetransmissionTimerDL-PTM)；
用于点对多点传输PTM的DRX下行混合自动重传请求HARQ往返时延RTT定时器(drx-HARQ-RTT-TimerDL-PTM)。
需要说明的是，对于非激活态组播业务，如果不支持HARQ反馈，则可以停止以下至少一个定时器：
用于点对多点传输PTM的DRX下行重传定时器(drx-RetransmissionTimerDL-PTM)；
用于点对多点传输PTM的DRX下行混合自动重传请求HARQ往返时延RTT定时器(drx-HARQ-RTT-TimerDL-PTM)。
综上，根据本公开实施例提供的媒体接入控制MAC重置定时器的处理方法，可在终端处于非激活态并执行组播业务数据接收时，在MAC重置过程中，控制MBS相关定时器不会被停止，进而使终端能够正常接收到非激活态组播业务数据，保证非激活态组播业务的正常执行。
图2示出了根据本公开实施例的一种媒体接入控制MAC重置定时器的处理方法的流程示意图。如图2所示，该方法应用于终端，且可以包括以下步骤。
步骤201、对于非激活态组播业务MBS，在媒体接入控制MAC重置过程中，终端根据协议约定对时间同步TA定时器执行控制操作。
当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有时间同步(Time Alignment,TA)定时器会被视为到期。在此种初始化操作下，会继续执行后续清空HARQ buffer以及下行HARQ链路配置的操作。而对于非激活态组播业务来说，不能清空HARQ buffer，一旦清空HARQ buffer，则在非激活态组播业务数据传输过程中发生数据包译码错误时，不能在HARQ buffer中查取译码错误的数据包，进而容易导致有用信息丢失或直接导致译码失败。故为了保证非激活态终端在MAC重置时，组播业务数据传输的完整性以及提高译码的准确率，防止丢失有用信息，在本公开实施例中，在媒体接入控制MAC重置过程中，终端根据协议约定对时间同步TA定时器执行视为到期操作后，进一步执行保留MBS相关HARQ buffer和/或保留MBS相关半持续调度SPS配置的操作。通过上述操作，可保证支持非激活态组播业务接收的终端，能够正常执行非激活态组播业务接收并减少组播业务数据的丢失。

图3示出了根据本公开实施例的一种媒体接入控制MAC重置定时器的处理方法的流程示意图。如图3所示，该方法应用于终端，基于图1、图2所示实施例，如图3所示，且可以包括以下步骤。
301、对于非激活态组播业务MBS，在媒体接入控制MAC重置过程中，终端根据协议约定对MBS相关定时器以及时间同步TA定时器执行控制操作。
当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有定时器会被停止，所有时间同步(Time Alignment,TA)定时器会被视为到期。在定时器被停止时，对于非激活态组播业务这一下行配 置业务来说，将会无法接收组播业务的业务数据，导致组播业务无法正常执行。在时间同步定时器被视为到期时，会继续执行后续清空HARQ buffer以及下行HARQ链路配置的操作。而对于非激活态组播业务来说，不能清空HARQ buffer，一旦清空HARQ buffer，则在非激活态组播业务数据传输过程中发生数据包译码错误时，不能在HARQ buffer中查取译码错误的数据包，进而容易导致有用信息丢失或直接导致译码失败。故为了保证终端针对非激活态组播业务MBS的正常执行以及保证非激活态终端在MAC重置时，组播业务数据传输的完整性以及提高译码的准确率，在媒体接入控制MAC重置过程中，终端可根据协议约定对MBS相关定时器以及时间同步TA定时器执行控制操作，在对时间同步TA定时器执行视为到期操作后，进一步执行保留指定HARQ buffer和/或保留MBS相关半持续调度SPS配置的操作。通过上述操作，可保证支持非激活态组播业务接收的终端，能够正常接收到非激活态组播业务，同时减少组播业务数据的丢失。

401、接收网络侧发送的非激活态组播业务MBS。
其中，网络侧可包括基站、核心网中的至少一种；终端可为非激活态终端；非激活态组播业务(Multicast Broadcast Service，MBS)为非激活态终端仍能执行业务数据接收的组播业务。网络侧可通过向非激活态终端发送非激活态组播业务MBS，以便非激活态终端在接收到MBS后，在响应执行MBS 过程中，执行对定时器的处理，防止MAC重置过程中会停止所有MBS相关定时器或将所有TA定时器视为到期。进一步使非激活态终端在执行MBS过程中，支持非激活态组播业务接收，并减少组播业务数据的丢失。
402、响应于执行非激活态组播业务MBS，在媒体接入控制MAC重置过程中，针对MBS相关定时器执行第一控制操作。
在现有机制中，当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有定时器会被停止。在此种初始化操作下，对于非激活态组播业务这一下行配置业务来说，将会无法接收组播业务的业务数据，导致组播业务无法正常执行。
基于此，在本公开实施例中，为了保证终端针对非激活态组播业务MBS的正常执行，在媒体接入控制MAC重置过程中，终端根据协议约定对MBS相关定时器执行第一控制操作，以避免MBS相关定时器被停止，而无法接收组播业务的业务数据。其中，第一控制操作可包括两种可能实现的方式：
作为一种可能实现方式，第一控制操作可为不停止MBS相关定时器。在该操作中，终端可以继续运行MBS相关定时器；或者，终端可以停止除了MBS相关定时器之外的所有定时器。
作为一种可能实现方式，第一控制操作可为停止MBS相关定时器，并之后重新启动MBS相关定时器。在该操作中，包括但不限于以下任意一种情况：
终端立刻重启MBS相关定时器；
终端在满足MBS相关定时器开启条件时重启MBS相关定时器；
终端在指定时刻重启MBS相关定时器，其中，指定时刻为根据协议约定或网络配置确定的。
其中，MBS相关定时器至少包括非连续性接收(Discontinuous Reception,DRX)配置相关定时器，DRX配置相关定时器包括但不限于以下至少一项：用于点对多点传输PTM的DRX激活态定时器(drx-onDurationTimerPTM)；用于点对多点传输PTM的DRX非激活态定时器(drx-InactivityTimerPTM)；用于点对多点传输PTM的DRX下行重传定时器(drx-RetransmissionTimerDL-PTM)；用于点对多点传输PTM的DRX下行混合自动重传请求HARQ往返时延RTT定时器(drx-HARQ-RTT-TimerDL-PTM)。额外的，对于非激活态组播业务，如果不支持HARQ反馈，则可以停止以下至少一个定时器：用于点对多点传输PTM的DRX下行重传定时器(drx-RetransmissionTimerDL-PTM)；用于点对多点传输PTM的DRX下行混合自动重传请求HARQ往返时延RTT定时器(drx-HARQ-RTT-TimerDL-PTM)。
综上，根据本公开实施例提供的媒体接入控制MAC重置定时器的处理方法，可在终端处于非激活态并执行组播业务数据接收时，在MAC重置过程中，控制MBS相关定时器不会被停止，进而使终端能够正常接收到非激活态组播业务数据，保证非激活态组播业务的正常执行。

501、接收网络侧发送的非激活态组播业务MBS。
502、响应于执行非激活态组播业务MBS，在媒体接入控制MAC重置过程中，针对时间同步TA定时器执行第二控制操作。
其中，第二控制操作可为将时间同步TA定时器执行视为到期。
503、保留指定HARQ buffer和/或保留MBS相关半持续调度SPS配置。
在现有机制中，当网络侧通过包含挂起配置的RRCRelease将终端释放到非激活态时，需要执行媒体接入控制(Medium Access Control，MAC)重置流程，在MAC重置流程中，所有时间同步(Time Alignment,TA)定时器会被视为到期。在此种初始化操作下，会继续执行后续清空HARQ buffer以及下行HARQ链路配置的操作。而对于非激活态组播业务来说，不能清空HARQ buffer，一旦清空HARQ buffer，则在非激活态组播业务数据传输过程中发生数据包译码错误时，不能在HARQ buffer中查取译码错误的数据包，进而容易导致有用信息丢失或直接导致译码失败。
基于此，在本公开实施例中，为了保证非激活态终端在MAC重置时，组播业务数据传输的完整性以及提高译码的准确率，防止丢失有用信息，在媒体接入控制MAC重置过程中，终端根据协议约定对MBS相关定时器执行将时间同步TA定时器执行视为到期后，进一步执行保留指定HARQ buffer和/或保留MBS相关半持续调度SPS配置的操作，以保证支持非激活态组播业务接收的终端，能够正常执行非激活态组播业务接收并减少组播业务数据的丢失。
针对本公开实施例，具体可分为三种可能实现方式：

作为一种可能实现方式：终端保留指定HARQ buffer以及保留MBS相关半持续调度SPS配置。进一步避免HARQ buffer以及MBS相关半持续调度SPS配置被清空，防止产生组播业务数据的丢失。其中，对于本公开实施例，在保留指定HARQ buffer以及保留MBS相关半持续调度SPS配置时，其实现过程与实施例步骤202c相同，在此不再赘述。
综上，根据本公开实施例提供的媒体接入控制MAC重置定时器的处理方法，可在终端处于非激活态并执行组播业务数据接收时，在MAC重置过程中，控制MBS相关定时器不会被停止，进而使终端能够正常接收到非激活态组播业务数据，保证非激活态组播业务的正常执行。同时，可避免MAC重置过程中，对HARQ进程进行完全的初始化，保证支持非激活态组播业务接收的终端，在处于非激活态并继续执行组播业务数据接收时，相关HARQ buffer以及MBS相关半持续调度SPS配置不会被清空，能够正常执行译码错误数据包的重传操作，从而能够保证非激活态终端在MAC重置时，组播业务数据传输的完整性以及提高译码的准确率，防止丢失有用信息。

其中，第一控制操作可为不停止MBS相关定时器，在该操作中，终端可以继续运行MBS相关定时器；或者，终端可以停止除了MBS相关定时器之外的所有定时器。此外，第一控制操作还可为停止MBS相关定时器，并之后重新启动MBS相关定时器。在该操作中，包括但不限于以下任意一种情况：终端立刻重启MBS相关定时器；终端在满足MBS相关定时器开启条件时重启MBS相关定时器；终端在指定时刻重启MBS相关定时器，其中，指定时刻为根据协议约定或网络配置确定的。第二控制操作可为将时间同步TA定时器执行视为到期。

702、向终端发送网络指示，网络指示用于终端重配置MBS相关SPS配置。
对于本公开实施例，网络侧还可向终端发送重配置MBS相关SPS配置的网络指示。进一步使支持非激活态组播业务接收的终端，将时间同步TA定时器视为到期之后，能够在进一步保留MBS相关半持续调度SPS配置时，根据所接收到的网络指示重配置MBS相关SPS配置。
综上，根据本公开实施例提供的媒体接入控制MAC重置定时器的处理方法，通过向终端发送网络配置以及网络指示，可使终端根据网络配置以及网络指示在MAC重置过程中执行对定时器的控制，以及对SPS配置信息的重新配置。可防止MAC重置过程中默认的对全部定时器执行停止动作，会对非激活态组播业务接收以及数据传输造成影响。以及防止清空MBS相关半持续调度SPS配置，会影响非激活态组播业务的接收或造成数据丢失。
