  • HARQ uses the Stop-and-Wait Protocol (Stop-and-Wait Protocol) to send data.

So that it matches the size of the RLC PDU indicated by the MAC layer.

Description

信息处理方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种信息处理方法、装置、设备及存储介质。
背景技术
在5G新空口(5G New Radio，5G NR)系统中，网络和终端设备之间通过重传机制实现数据的可靠传输。在下行无线链路控制过程中，网络为终端半静态配置了一个无线链路控制(radio link control，RLC)重组定时器，以控制终端设备执行RLC丢包或者RLC重传的时机。
目前，在NR的非地面通信网络(non terrestrial network，NTN)中，由于终端设备与卫星之间的信号传播时延大幅增加，发展出了通过关闭混合自动重传请求(hybrid automatic repeat request，HARQ)反馈功能和关闭HARQ重传功能的方式来降低数据传输时延，并且在网络设备不支持盲调度重传时，可以通过网络设备静态配置RLC重组定时器的方式来保证传输可靠性。
但是，在NTN的非地球同步轨道(geostationary earth orbit，GEO)场景中，由于终端设备与网络设备之间的时延不断变化，静态配置RLC重组定时器的方式不能很好的适应终端设备与网络设备之间的时延变化，可能出现由于RLC重组定时器的时长配置不合适导致过早或者过晚执行RLC丢包或者RLC重传的现象，降低了用户业务体验差。

相比于地面蜂窝网通信，卫星通信具有很多独特的优点：首先，卫星通信不受用户地域的限制，例如，一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此，理论上地球上每一个角落都可以被卫星通信覆盖；其次，卫星通信有较大的社会价值，卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展；再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
因而，在NTN中，通过将基站或者部分基站功能部署在高空平台或者卫星上为终端设备提供无缝覆盖，并且高空平台或者卫星受自然灾害影响较小，能提升5G系统的可靠性。
下面首先简要介绍一下本申请实施例适用的一种通信系统的架构示意图。
图1为本申请实施例提供的一种通信系统的结构示意图。如图1所示，网络设备和终端设备1至终端设备6可以组成一个通信系统，该通信系统中，终端设备1至终端设备6中的任意终端设备可以向网络设备发送上行数据或接收网络设备发送的下行数据。此外，终端设备4至终端设备6也可以组成一个通信系统，该通信系统中，终端设备4或终端设备6可以向终端设备5发送上行数据，或者接收终端设备5发送的下行数据。
示例性的，图1所示的通信系统还可以包括通信卫星，该通信卫星可以作为终端设备1至终端设备6中至少一个终端设备与网络设备1的中转站，为终端设备1至终端设备6提供服务。
在本申请的实施例中，终端设备可以是终端设备1至终端设备6中的任意一个终端设备，网络设备可以是为终端设备1至终端设备6提供服务的基站，也可以是作为终端设备1至终端设备6与网络设备中转站的通信卫星。

通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

本申请实施例中涉及的网络设备，可以是普通的基站(如NodeB或eNB或者gNB)、新无线控制器(new radio controller，NR controller)、集中式网元(centralized unit)、新无线基站、射频拉远模块、微基站、中继(relay)、分布式网元(distributed unit)、接收点(transmission reception point，TRP)、传输点(transmission point，TP)或者任何其它设备。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述，本申请所有实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备。

下面，首先介绍一下本申请可能涉及的通信卫星、5G NR中的混合自动重传请求(hybrid automatic repeat request，HARQ)机制以及5G NR中的无线链路控制(radio link control，RLC)分段和数据重组。
通信卫星：
在卫星的应用中，根据提供服务的通信卫星所在的轨道高度，通信卫星可分为地球同步轨道(geostationary earth orbit，GEO)卫星和非地球同步轨道(Non-GEO)卫星。其中，非地球同步轨道卫星又可以分为低地球轨道(low earth orbit，LEO)卫星、中地球轨道(medium-earth orbit，MEO)卫星和高椭圆轨道(high elliptical orbit，HEO)卫星等。其中，由于LEO卫星和GEO卫星的轨道高度低，传播时延小，成为全球通信领域中的主要研究对象。
其中，LEO卫星的轨道高度范围为500km～1500km，轨道周期约为1.5小时～2小时。终端设备与LEO间的单跳通信的信号传播延迟一般小于20ms，最大卫星可视时间为20分钟。也即，终端设备与LEO间的信号传播距离短，链路损耗少，对终端设备的发射功率要求不高。
GEO卫星的轨道高度为35786km，围绕地球旋转周期为24小时。终端设备与LEO间的单跳通信的信号传播延迟一般为250ms。
通常情况下，为了保证卫星的覆盖范围以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
5G NR中的HARQ机制：
5G NR有两级重传机制：媒质接入控制(medium access control，MAC)层的HARQ机制和RLC层的自动重传请求(automatic repeat request，ARQ)机制。其中，MAC层的HARQ机制主要处理丢失或出错的数据的重传，RLC层的ARQ主要用于对MAC层的HARQ机制进行补充。MAC层的HARQ机制能够提供快速重传，RLC层的ARQ机制能够提供可靠的数据传输。
在实际应用中，HARQ使用停等协议(Stop-and-Wait Protocol)来发送数据。在停等协议中，发送端发送一个传输块(transport block，TB)后，就停下来等待确认信息。这样，发送端在每次传输后就停下来等待确认，会导致用户的吞吐量很低。因此，NR中可以使用多个并行的HARQ进程，这些HARQ进程共同组成了一个HARQ实体，这个HARQ实体结合了停等协议，允许数据连续传输，也即，在一个HARQ进程等待确认信息时，发送端可以使用另一个HARQ进程继续发送数据，从而保证了数据的连续传输。
可以理解的是，HARQ有上行HARQ和下行HARQ之分。上行HARQ针对上行数据传输，下行HARQ针对下行数据传输，且两者相互独立。
基于目前NR协议的规定，终端设备对应的每个服务小区都有各自的HARQ实体，每个HARQ实体维护一组并行的下行HARQ进程和一组并行的上行HARQ进程。
目前，每个上下行载波均支持最大16个HARQ进程。网络设备可以根据网络部署情况通过无线资源控制(radio resource control，RRC)信令发送的半静态配置信息，向终端设备指示最大的HARQ进程数。如果网络设备没有提供关于HARQ的配置参数，则下行缺省的HARQ进程数为8，上行每个载波支持的最大HARQ进程数始终为16。每个HARQ进程对应一个HARQ进程ID。
对于下行传输，广播控制信道(broadcast control channel，BCCH)使用一个专用的广播HARQ进程。对于上行传输，随机过程中的Msg3传输使用HARQ ID 0。
对于不支持下行空分复用的终端设备，每个下行HARQ进程只能同时处理1个TB；对于支持下行空分复用的终端，每个下行HARQ进程可以同时处理1个或者2个TB。终端设备的每个上行HARQ进程同时处理1个TB。
HARQ在时域上分为同步和异步两类，在频域上分为非自适应和自适应两类。NR上下行均使用异步自适应HARQ机制。异步HARQ机制，即重传可以发生在任意时刻，同一个TB的重传与上一次传 输的时间间隔是不固定的，自适应HARQ机制可以改变重传所使用的频域资源和调制与编码策略(modulation and coding scheme，MCS)。
5G NR中的RLC分段和数据重组：
在实际应用中，终端设备的每个逻辑信道都有一个RLC实体，每个RLC实体可以配置为TM、UM、AM三种模式中的任意一种。其中，逻辑信道是在物理信道上传递不同信息种类构成的信道，通常可以分为控制信道和业务信道。
可选的，透传模式(transparent mode，TM)对应TM RLC实体。该模式可以认为是空的RLC，因为这种模式下只提供数据的透传功能。
非确认模式(unacknowledged mode，UM)对应UM RLC实体。该模式提供除重传、重分段、重复包检测、协议错误检测外的所有RLC功能，因此，提供了一种不可靠的传输服务。
确认模式(acknowledged mode，AM)对应AM RLC实体，该模式通过出错检测和重传，提供了一种可靠的传输服务。该模式支持RLC的所有功能。
其中，UM和AM可以支持RLC业务数据单元(service data unit，SDU)的分段和重组功能。由于发送端每次传输的资源大小是由MAC层调度器决定的，其大小通常不能完全匹配RLC协议数据单元(protocol data unit，PDU)的大小，所以，发送端需要对RLC SDU进行分段，以便其匹配MAC层指示RLC PDU的大小。相应地，接收端需要对所有接收到的RLC PDU片段进行重组，以便恢复出原来的RLC SDU，并递交给上层(分组数据汇聚协议(packet data convergence protocol，PDCP)层)。
对于下行(down link，DL)AM RLC和DL UM RLC，网络设备可以通过RRC指令为终端设备配置一个RLC重组定时器(t-Reassembly)，通过RLC重组定时器来控制终端设备重组以得到RLC SDU的时间。
可选的，启动RLC重组定时器的条件为：如果终端设备从MAC层接收到一个PDU分段，且位于该PDU分段之前的至少一个比特(byte)还没有被接收到，若此时RLC重组定时器处于未运行状态，则启动RLC重组定时器。
如果终端设备使用RLC重组定时器的时长达到配置时长，则意味了终端设备等待的多个比特中至少还有一个比特还没有被接收到，此时可以执行如下操作：
对于DL UM RLC，终端设备会触发丢弃相应的已接收到的非确认模式数据(UM Data，UMD)PDU；
对于DL AM RLC，终端设备会触发RLC状态报告，告知网络设备哪些RLC SDU没有正确接收，网络设备在接收到RLC状态报告后会触发未正确接收的RLC SDU的重传。
现阶段，在NR中，在终端设备侧，RLC重组定时器的配置信息通常由网络设备通过RRC信令进行半静态配置，RLC重组定时器的配置信息可以反映终端设备在接收到一个RLC SDU的分段后，对于之前已传输但还没有正确接收的该RLC SDU的其他分段可以等待的最长时间。
在NR中，由于RLC SDU分段乱序到达接收端，主要是由于MAC层的HARQ传输机制导致的，比如，一个RLC SDU被分成了RLC SDU分段1和RLC SDU分段2，且2个分段先后被传输出去，假设先传输的RLC SDU分段1在MAC层经历了1次初传和2次重传才被接收端接收到，后传输的RLC SDU分段2在MAC层经历了1次初传就被接收端正确接收，则终端设备就有可能先接收到RLC SDU分段2，此时，终端设备会启动RLC重组定时器，并在该RLC重组定时器的运行时间内等待接收RLC SDU分段1。
NTN与NR采用的蜂窝网络相比，NTN中终端设备与通信卫星之间的信号传播时延大幅增加，因此，一方面，在NTN标准化过程中，正在讨论如何在现有基础上进一步扩展RLC重组定时器的取值范围；另一方面，标准化过程中也发展出了通过关闭HARQ反馈功能和关闭HARQ重传功能的方式来降低数据传输时延，此时，在关闭HARQ反馈功能和关闭HARQ重传功能的情况下，网络设备可以通过盲调度重传或者RLC ARQ重传来保证数据传输的可靠性。
可选的，在关闭HARQ反馈功能和关闭HARQ重传功能的情况下，如果网络设备也不支持(没有配置)盲调度，即RLC SDU分段后的每个MAC PDU在MAC层只有一次传输机会。
在没有MAC重传的情况下，对于GEO场景，由于终端设备与网络设备之间的时延基本不变或者变化很慢，此时，可以将RLC重传定时器的时长配置为0；而对于非GEO场景(包括：LEO场景、MEO场景、HEO场景)，由于终端设备与网络设备之间的时延不断变化，如果按照现有静态配置RLC重组定时器的方式，无法很好的适应终端设备与网络设备之间时延的不断变化，相应的，对于UM模式，会造成终端设备过早或者过晚地丢包，对于AM模式，会造成网络设备不必要地或者过晚地触发RLC重传，影响了用户的业务体验。
针对上述问题，本申请实施例提供了一种信息处理方法，在下行HARQ反馈功能和HAQR重传功能均关闭，且确定RLC实体的RLC模式时，一种实现方式为网络设备根据RLC实体的RLC模式，确 定与RLC模式对应的RLC重组定时器的配置信息，并下发至终端设备，以使终端设备根据网络设备的指示确定RLC重组定时器的定时器信息；另一种实现方式为终端设备根据RLC实体的RLC模式，确定与RLC模式对应的RLC重组定时器的配置信息，并确定RLC重组定时器的定时器信息，这两种实现方式均可使得终端设备侧的RLC重组定时器的定时器信息更好地匹配终端设备与网络设备之间信号传输时延的变化，避免了由于RLC重组定时器的时长配置不合适导致过早或者过晚的RLC丢包或者RLC重传，提高了用户的业务体验。
具体的，本申请针对NTN系统中特别是在非GEO场景下终端设备与通信卫星之间的无线信号传输时延快速变化的特性，提供了一种在NTN中关闭下行HARQ反馈功能且关闭HARQ重传功能的情况下，动态调整终端设备侧RLC重组定时器时长的方法，使得终端侧的RLC重组定时器时长能够更好地匹配终端与网络之间信号传输时延的变化。
本申请的整体思路为：通过网络控制或者终端自主的方式来动态调整终端RLC重组定时器时长。具体来说有以下几种实现形式：
实现形式1：网络设备控制调整终端设备侧的RLC重组定时器的时长。在关闭下行HARQ反馈功能并且关闭HARQ重传的情况下，对于DL AM RLC和DL UM RLC，网络设备根据自己和终端设备的移动规律确定终端设备的RLC重组定时器长度的调整周期和调整步长，并告知终端设备。终端设备根据网络设备的指示来周期性地调整RLC重组定时器时长。
实现形式2：网络设备控制调整终端设备侧RLC重组定时器的时长。实现方式2与实现方式1的共同点是RLC重组定时器的配置信息均由网络设备确定，并下发给终端设备，以使终端设备根据网络设备的指示调整RLC重组定时器的时长。实现方式2与实现方式1的不同点在于：在关闭下行HARQ反馈功能且关闭HARQ重传的情况下，对于DL AM RLC和DL UM RLC，网络设备根据自己和终端设备的移动规律直接确定终端设备的RLC重组定时器的时长，并通过终端下行调度的PDCCH或者MAC CE将RLC重组定时器的时长告知终端设备，这样终端设备可以根据网络设备确定的RLC重组定时器的时长对RLC重组定时器进行调整。
实现形式3：终端设备可以自主调整终端设备侧RLC重组定时器的时长。在关闭下行HARQ反馈功能并且关闭HARQ重传的情况下，对于DL AM RLC和DL UM RLC，终端设备的RLC重组定时器的时长的调整由终端设备自行调整。终端设备根据星历信息和自己所处的位置可以获知自己和网络设备之间信号传输时延的变化规律，根据该时延变化规律确定RLC重组定时器的时长。
下面，通过具体实施例对本申请的技术方案进行详细说明。需要说明的是，本申请的技术方案可以包括以下内容中的部分或全部，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本申请提供的信息传输方法实施例一的交互示意图。该方法以终端设备和网络设备之间的信息交互进行说明。参照图2所示，该信息处理方法可以包括如下步骤：
S201、网络设备和终端设备在下行HARQ反馈功能和HAQR重传功能均关闭时，均确定RLC实体的RLC模式。
在5G NG的实际应用中，网络设备会为终端设备与网络设备之间的每个逻辑信道配置一个RLC实体，并且通过高层信令将RLC的配置信息发送给终端设备，以使终端设备为每个RLC实体配置一种RLC模式。可选地，高层信令可以为RRC信息或MAC控制单元(control element，CE)信息。
在本申请的实施例中，对于NTN的非GEO场景，为了降低终端设备和网络设备之间的数据传输时延，网络设备和终端设备之间的下行HARQ反馈功能和HAQR重传功能均关闭，此时，为了保证数据传输的可靠性，网络设备和终端设备均需要确定逻辑信道对应RLC实体的RLC模式。
可选的，由上述应用场景介绍的内容可知，每个RLC实体的RLC模式可以为TM、UM或者AM中的任意一种。
示例性的，RLC实体的RLC模式由网络设备配置，网络设备可以根据预先配置的信息确定RLC实体的RLC模式，终端设备可以根据网络设备下发的配置信息确定RLC实体的RLC模式。
S202、网络设备根据RLC实体的RLC模式，确定与所述RLC模式对应的RLC重组定时器的配置信息。
在本实施例中，由于RLC实体的UM和AM可以支持传输数据的分段和重组功能，因而，在RLC实体的RLC模式包括下行DL AM、下行DL UM中的任意一种时，网络设备可以控制与该RLC模式对应的RLC重组定时器的配置信息。
示例性的，在RLC实体的RLC模式为双向确认模式(双向AM)或下行非确认模式(下行UM)或双向非确认模式(双向UM)时，网络设备可以配置终端设备侧RLC重组定时器，从而确定终端设备侧RLC重组定时器的配置信息。可以理解的是，双向AM包含1个上行(up link，UL)AM和1个 DL AM，双向UM包含1个UL UM和1个DL UM，下行UM即单向DL UM。
可选的，在本实施例中，RLC重组定时器的配置信息可以包括如下两种形式：
实现方式1：RLC重组定时器的配置信息包括：RLC重组定时器的初始时长、调整周期和调整步长；
实现方式2：RLC重组定时器的配置信息包括：RLC重组定时器的时长。
关于每种实现方式下确定RLC重组定时器的配置信息的方法参见下述实施例的介绍，此处不再赘述。
S203、网络设备向终端设备发送RLC重组定时器的配置信息。
在本申请的实施例中，网络设备确定出终端设备侧RLC重组定时器的配置信息后，将该RLC重组定时器的配置信息发送给终端设备，以使得终端设备可以及时调整RLC重组定时器的时长(启动时长)。
作为一种示例，在RLC重组定时器的配置信息包括RLC重组定时器的初始时长、调整周期和调整步长时，网络设备可以通过RRC信令或MAC CE等，将RLC重组定时器的配置信息发送给终端设备。也即，通过RRC信令或MAC CE指示的方式主要适用于预配置资源的下行传输中。
作为另一种示例，在RLC重组定时器的配置信息包括：RLC重组定时器的时长时，网络设备可以通过下行控制信道或MAC CE，将RLC重组定时器的配置信息发送给终端设备。
具体的，网络设备在动态调度的下行传输中，可以通过指示下行调度的PDCCH，同时指示终端设备当前的RLC重组定时器的时长。网络设备在动态调度的下行传输和预配置资源的下行传输中，可以通过下行MAC CE指示终端设备当前的RLC重组定时器的时长。
S204、终端设备获取网络设备配置的与RLC模式对应的RLC重组定时器的配置信息。
在本申请的实施例中，终端设备在确定下行HARQ反馈功能和HAQR重传功能均关闭，且确定出RLC实体的RLC模式时，可以获取网络设备配置的RLC重组定时器的配置信息。
具体的，终端设备可以直接接收网络设备下发的指示信息，也可以从其他的设备获取网络设备确定的RLC重组定时器的配置信息。本申请实施例并不限定终端设备获取RLC重组定时器的配置信息的具体方式，其可以根据实际应用场景确定，此处不再赘述。
S205、终端设备根据该RLC重组定时器的配置信息，确定RLC重组定时器的定时器信息。
在本申请的实施例中，终端设备获取到网络设备配置的RLC重组定时器的配置信息时，便可以确定出RLC重组定时器的定时器信息，为后续及时调整RLC重组定时器的时长奠定了基础，这样终端设备在满足RLC重组定时器的启动条件时，能够基于获取到的RLC重组定时器的配置信息控制RLC重组定时器的运行时长。
进一步的，在本申请的实施例中，在上述S205之后，该方法还可以包括如下步骤：
S206、终端设备根据RLC重组定时器的定时器信息，调整RLC重组定时器的时长。
在本实施例中，终端设备得出RLC重组定时器的定时器信息，便可以调整RLC重组定时器的时长。
作为一种示例，在RLC重组定时器的定时器信息包括RLC重组定时器的初始时长、调整周期和调整步长时，终端设备便基于最新接收到的RLC重组定时器的初始时长、调整周期和调整步长调整RLC重组定时器的时长。
具体的，以RLC重组定时器的初始时长为起始时长，根据RLC重组定时器的调整周期和调整步长，周期性调整RLC重组定时器的时长。
在本实施例中，终端设备获取到网络设备指示的RLC重组定时器的初始时长、调整周期和调整步长时，可以基于该指示来调整RLC重组定时器的时长。即，RLC重组定时器的初始时长为网络设备配置并指示的值，同时，终端设备按照网络设备配置的调整周期和调整步长周期性地调整RLC重组定时器的时长。
作为另一种示例，在RLC重组定时器的定时器信息包括RLC重组定时器的时长时，终端设备便基于最新接收到的RLC重组定时器的时长更新RLC重组定时器的时长。
本申请实施例提供的信息处理方法，在下行HARQ反馈功能和HAQR重传功能均关闭时，网络设备根据RLC实体的RLC模式，确定与RLC模式对应的RLC重组定时器的配置信息，并下发至终端设备，这样，终端设备可以根据获取网络设备配置的RLC重组定时器的配置信息，并确定RLC重组定时器的定时器信息。该技术方案中，终端设备根据网络设备指示的RLC重组定时器的时长，能够更好地匹配终端设备与网络设备之间信号传输时延的变化，避免了过早或者过晚的RLC丢包或者RLC重传现象，提高了用户的业务体验。
更进一步的，在本申请的实施例中，该方法还可以包括如下步骤：
终端设备在确定RLC重组定时器满足启动条件时，启动RLC重组定时器。
其中，该启动条件为在接收到第一数据时，位于该第一数据之前的至少一个比特还未被接收到，且该RLC重组定时器当前未处于运行状态。
具体的，在实际应用中，对于每个配置了DL AM RLC或DL UM RLC的RLC实体，终端设备使用RLC重组定时器的方法是：终端设备在确定RLC重组定时器满足上述启动条件，则启动RLC重组定时器。
可以理解的是，该启动条件也可以是RLC重组定时器的重启条件，即，终端设备首次启动RLC重组定时器后，若RLC重组定时器的运行时间达到RLC重组定时器的时长时关闭，当RLC重组定时器再次满足启动条件时，终端设备可以重新启动该RLC重组定时器。
在本申请的一种实施例中，在RLC重组定时器的配置信息包括：RLC重组定时器的初始时长、调整周期和调整步长时，该RLC重组定时器的启动时长为启动RLC重组定时器的时刻，该RLC重组定时器的时长。
示例性的，图3为终端设备根据RLC重组定时器的初始时长、调整周期和调整步长维护和使用RLC重组定时器的示意图。参照图3所示，在终端设备维护RLC重组定时器时，若终端设备首次接收到的RLC重组定时器的配置信息为初始时长t1、调整周期T1和调整步长s1，则终端设备基于该初始时长t1、调整周期T1和调整步长s1维护RLC重组定时器。示例性的，RLC重组定时器tR在第一个调整周期T1内的时长tR0等于初始时长t1，在第二个调整周期T1内的时长tR1为在第一个调整周期T1内的时长t1与调整步长s1的和，在后续的调整周期内，以此类推。
可选的，在终端设备基于初始时长t1、调整周期T1和调整步长s1维护RLC重组定时器的第三个调整周期T1内，若接收到网络设备下发的更新配置信息(包括初始时长t2、调整周期T2和调整步长s2)时，终端设备可以将正在维护的RLC重组定时器的第三个周期T1变更为第一个调整周期T2，相应的，RLC重组定时器的时长tR2变更为初始时长t2，并且RLC重组定时器在第二个调整周期T2内的时长为初始时长t2与调整步长s2的和，在后续的调整周期内，以此类推。
参照图3所示，在终端设备使用RLC重组定时器时，在终端设备基于初始时长t1、调整周期T1和调整步长s1维护RLC重组定时器的第二个调整周期T1内，启动RLC重组定时器，此时，RLC重组定时器的时长为tR1，则RLC重组定时器在运行时长tR1后超时。此外，在终端设备基于初始时长t2、调整周期T2和调整步长s2维护RLC重组定时器的第一个调整周期T2内，启动RLC重组定时器，此时，RLC重组定时器的时长为tR2，则RLC重组定时器在运行时长tR2时，重启RLC重组定时器，由于此次重启在第二个调整周期T2内，此时RLC重组定时器的时长为第二个调整周期T2内的时长tR3，即，时长tR3为时长tR2与调整步长s2的和。
在本申请的一种实施例中，在RLC重组定时器的配置信息包括：RLC重组定时器的时长时，该RLC重组定时器的启动时长为终端设备最近一次接收到的RLC重组定时器的时长。
示例性的，图4为终端设备根据RLC重组定时器的时长维护和RLC重组定时器的示意图。参照图4所示，在本实施例中，终端设备在t0时刻接收到通过RRC信令，指示RLC重组定时器的时长为tR0，随后，在t1时刻接收到通过物理下行控制信道(physical downlink control channel，PDCCH)指示的第一下行调度信息，同时，该下行控制信道还指示RLC重组定时器的时长tR1，在t2时刻时，终端设备通过物理下行共享信道(physical downlink shared channel，PDSCH)接收到第一下行数据信息，并且，可以基于接收到的下行数据信息确定下行数据信息是否接收完整，若确定下行数据信息未接收完整，则确定RLC重组定时器满足启动条件，启动RLC重组定时器，此时，RLC重组定时器的时长为tR1。
示例性的，参照图4所示，终端设备在t3时刻接收到通过下行控制信道指示的第二下行调度信息，同时，该下行控制信道还指示RLC重组定时器的时长为tR2，相应的，在t4时刻时，终端设备接收到第二下行数据信息。
终端设备在t5时刻接收到通过下行控制信道指示的第三下行调度信息，此时，该下行控制信道未指示RLC重组定时器的时长，因而，终端设备确定RLC重组定时器的时长保持tR2不变，在t6时刻时，终端设备接收到第三下行数据信息，并且确定RLC重组定时器满足启动条件，启动RLC重组定时器，此时，RLC重组定时器的时长为tR2。
相应的，终端设备在t7时刻接收到通过下行控制信道指示的第四下行调度信息，此时，该下行控制信道指示RLC重组定时器的时长为tR3，因而，在t8时刻时，终端设备接收到第四下行数据信息，并且确定RLC重组定时器满足重启条件，则重启RLC重组定时器，此时，RLC重组定时器的时长为tR3，相应的，RLC重组定时器在运行时长tR3后超时。
示例性的，在本申请的一种可能设计中，若RLC重组定时器的配置信息包括RLC重组定时器的 初始时长、调整周期和调整步长，此时，上述S202中确定终端设备侧RLC重组定时器的配置信息可以通过如下可能两种可能设计方式实现：
作为一种示例，在网络设备已知终端设备的位置信息时，终端设备可以根据终端设备的位置信息、卫星的运动规律和卫星当前的位置信息，确定RLC重组定时器的配置信息，从而确定了终端设备侧的RLC重组定时器时长的调整周期和调整步长。其中，该卫星是为终端设备提供服务的网络设备或设置在网络设备与终端设备之间的中间站。
具体的，网络设备可以根据终端设备的位置信息和卫星当前的位置信息，确定该RLC重组定时器的初始时长，根据终端设备的位置信息和卫星的运动规律，确定RLC重组定时器的调整周期和调整步长。
在本实施例中，网络设备可以基于终端设备的位置信息和卫星当前的位置信息，可以计算出终端设备与网络设备之间的信号传输时延，进而根据该信号传输时延，为RLC重组定时器配置一个初始时长。随后，网络设备再根据终端设备的位置信息和卫星的运动规律，确定终端设备与网络设备之间的信号传输时延的变化规律，再根据该信号传输时延的变化规律，为RLC重组定时器配置调整周期和调整步长。
可以理解的是，关于调整周期和调整步长与信号传输时延变化规律的具体关系，可以参照下述图6所示实施例中，终端设备设置RLC重组定时器的实现方案，此处不再赘述。
作为另一种示例，在网络设备未知终端设备的位置信息时，RLC重组定时器的配置信息是预先定义的，或者，RLC重组定时器的配置信息是根据预设规则确定的。
具体的，如果网络设备不知道终端设备的位置信息，此时，终端设备侧RLC重组定时器时长可以配置为一个较大的值，比如：RLC重组定时器的时长被配置为服务小区覆盖的地面范围内、距离该卫星最远的地面位置与网络设备之间的信号传输时延，同时，终端设备侧RLC重组定时器时长的调整周期和调整步长被配置为0。
示例性的，如果终端设备在之前没有向网络设备上报过位置信息，或者，终端设备的位置信息发生变更时，终端设备则向网络设备上报其所处的位置信息。相应的，网络设备可以结合终端设备上报的位置信息和卫星的运动规律，调整终端设备的RLC重组定时器的初始时长和/或调整周期和/或调整步长，再通过RRC信令或者MAC CE向终端设备指示新的RLC重组定时器的初始时长和/或调整周期和/或调整步长。
在本实施例中，网络设备根据终端设备上报的位置信息调整RLC重组定时器的配置信息，并下发给终端设备，使得RLC重组定时器的配置信息能够很好的匹配终端设备与网络设备之间的信号传输时延，可以很好的降低过早或者过晚的RLC丢包或者RLC重传。
示例性的，在本申请的另一种可能设计中，RLC重组定时器的配置信息包括：RLC重组定时器的时长。
具体的，在关闭下行HARQ反馈功能并且关闭HARQ重传的情况下，对于DL AM RLC和DL UM RLC，终端设备的RLC重组定时器时长的调整由网络设备控制。网络设备可以根据自己和终端的移动规律确定终端设备的RLC重组定时器的时长。
在考虑到终端设备在接收到下行传输信息后才有可能启用RLC重组定时器，因此，网络设备可以在用于指示终端设备的下行调度信息的PDCCH中或者通过MAC CE，将终端设备的RLC重组定时器的时长告知终端。
作为一种示例，在RLC重组定时器的配置信息包括RLC重组定时器的时长，且网络设备已知终端设备的位置信息时，上述S202中确定终端设备侧RLC重组定时器的配置信息可以通过如下可能实现方式实现：
根据终端设备的位置信息、卫星的运动规律和卫星当前的位置信息，确定RLC重组定时器的时长。
在本实施例中，网络设备可以基于终端设备的位置信息、卫星的运动规律、卫星当前的位置信息，计算出终端设备与网络设备之间的信号传输时延和信号传输时延的变化规律，再根据该信号传输时延的变化规律，设定RLC重组定时器的时长。
作为另一种示例，在RLC重组定时器的配置信息包括RLC重组定时器的时长，且网络设备未知终端设备的位置信息时，RLC重组定时器的配置信息是预先定义的，或者，RLC重组定时器的配置信息是根据预设规则确定的。
示例性的，若果网络设备在确定RLC重组定时器的时长时，还不知道终端设备的位置信息，此时，网络设备可以将终端设备侧的RLC重组定时器的时长配置为一个较大的值。
例如，RLC重组定时器的时长被配置为服务小区覆盖的地面范围内、距离该卫星最远的地面位置与网络设备之间的信号传输时延。
进一步的，如果终端设备没有向网络设备上报过位置信息，或者，终端设备的位置发生变更时，终端设备则向网络设备上报位置信息，以使网络设备可以结合终端设备的位置确定出匹配度较高的RLC重组定时器的时长。
示例性的，在本申请上述实施例的基础上，图5为本申请提供的信息处理方法实施例二的流程示意图。参照图5所示，该方法还可以包括如下步骤：
S501、网络设备确定RLC重组定时器在当前下行传输时刻的配置信息。
在本申请的实施例中，由网络设备确定并指示的RLC重组定时器的配置信息，由于网络设备可以在下行控制信道上将RLC重组定时器的配置信息同下行调度信息一同发送给终端设备，因而，网络设备可以在每个下行传输时刻确定出RLC重组定时器的配置信息。
S502、网络设备根据该RLC重组定时器在前一次下行传输时刻的配置信息和当前下行传输时刻的配置信息，判断RLC重组定时器的配置信息是否发生变化。
在本实施例中，网络设备在确定出当前下行传输时刻的RLC重组定时器的配置信息后，可以将其与前一次下行传输时刻时指示的RLC重组定时器的配置信息进行比较，判断当前下行时刻时，RLC重组定时器的配置信息是否发生变化，再根据判断结果确定是否需要下发给终端设备。
S503、网络设备在RLC重组定时器的配置信息未发生变化时，在当前下行传输时刻的下行传输过程中不携带RLC重组定时器的配置信息。
在本实施例中，若网络设备确定RLC重组定时器在前一次下行传输时刻的配置信息和当前下行传输时刻的配置信息未发生变化，此时，在下行传输过程中可以不携带RLC重组定时器的配置信息，以降低不必要的资源浪费，提高资源的利用率。
本申请实施例提供的信息处理方法，网络设备还可以确定RLC重组定时器在当前下行传输时刻的配置信息，根据该RLC重组定时器在前一次下行传输时刻的配置信息和当前下行传输时刻的配置信息，判断RLC重组定时器的配置信息是否发生变化，进而在RLC重组定时器的配置信息未发生变化时，在当前下行传输时刻的下行传输过程中不携带RLC重组定时器的配置信息，降低了不必要的资源浪费，提高了下行传输过程的资源利用率。
进一步的，在本申请的实施例中，如果网络设备的本次下行传输对应于多个逻辑信道的下行传输，由于每个配置了DL AM RLC或者DL UM RLC的逻辑信道分别对应一个RLC重组定时器，这时可以在下行控制信道或者MAC CE中针对每个配置了DL AM RLC或者DL UM RLC的逻辑信道，分别指示RLC重组定时器的时长。这样，终端设备可以得到准确的RLC重组定时器的时长，提高了匹配精度。
示例性的，图6为本申请提供的信息处理方法实施例三的流程示意图。该方法执行主体为终端设备。终端设备在下行HARQ反馈功能并且HARQ重传功能关闭且确定RLC实体的RLC模式的情况下，终端设备可以自行根据RLC实体的RLC模式，确定与RLC模式对应的RLC重组定时器的配置信息，并确定出RLC重组定时器的定时器信息。可选的，终端设备可以根据星历信息和自己所处的位置可以获知自己和网络设备之间信号传输时延的变化规律，进而根据该时延变化规律确定RLC重组定时器长度。参照图6所示，该信息处理方法可以包括如下步骤：
S601、终端设备在下行HARQ反馈功能和HAQR重传功能均关闭时，确定RLC实体的RLC模式。
在5G NG的实际应用中，网络设备会为终端设备与网络设备之间的每个逻辑信道配置一个RLC实体，并且为每个RLC实体配置一种RLC模式，而且，每个RLC实体的RLC模式可以为TM、UM或者AM中的任意一种。
在本实施例中，对于NTN的非GEO场景，网络设备和终端设备之间的下行HARQ反馈功能和HAQR重传功能均关闭时，为了确定是否需要配置RLC重组定时器的信息，终端设备首先需要确定逻辑信道对应RLC实体的RLC模式。
S602、终端设备根据RLC实体的RLC模式，确定与RLC模式对应的RLC重组定时器的配置信息。
在本申请的实施例中，由于RLC实体的UM和AM可以支持传输数据的分段和重组功能，因而，在RLC实体的RLC模式包括下行AM、下行UM中的任意一种时，终端设备需要基于RLC重组定时器的配置信息维护RLC重组定时器。
示例性的，RLC实体的RLC模式可以具体为双向确认模式(双向AM)或下行非确认模式(下行UM)或双向非确认模式(双向UM)。
在本实施例中，终端设备可以基于星历信息，以及自己所处的位置，获知自己与网络设备之间的信号传输时延的变化规律，从而自行调整RLC重组定时器时长。
具体的，该S602具体可以通过如下两个步骤实现：
A1：基于星历信息和终端设备的位置信息，确定终端设备与网络设备之间的信号传输时延的变化规律。
示例性的，卫星星历信息是描述卫星运动轨道的信息，具体来说，卫星星历就是一组对应某一时刻的轨道参数及其变化率，有了卫星星历信息就可以计算出任意时刻的卫星位置及其速度，因而，终端设备再结合自己的位置信息，则可以确定出该终端设备与网络设备之间的信号传输时延的变化规律。
A2：根据终端设备与网络设备之间的信号传输时延的变化规律，确定RLC重组定时器的配置信息。
在本实施例中，由于终端设备与网络设备之间的信号传输时延的变化规律有多种，这时，终端设备则可以基于预设规则对RLC重组定时器的时长进行配置。
示例性的，在本实施例中，根据终端设备与网络设备之间的信号传输时延的变化规律，该步骤A2可以通过如下几种方式实现：
作为一种示例，在网络设备为终端设备提供服务期间，若终端设备与该网络设备之间的信号传输时延逐渐变大，则确定该RLC重组定时器的时长为0，该网络设备是当前为终端设备提供服务的卫星。
可选的，图7为终端设备与网络设备之间的信号传输时延逐渐变大的示意图。如图7的(a)所示，在当前卫星为该终端设备提供通信服务期间，随着卫星的移动，卫星逐渐远离终端设备，即终端设备与网络设备之间的信号传输时延的变化规律为终端设备与网络设备之间的信号传输时延逐渐变大，时延与时间的曲线变化示意图参照图7的(b)所示。
对于这种情况，由于终端设备与网络设备之间的信号传输时延逐渐变大，则网络设备向终端设备传输的多个数据分段中，顺序在后的数据分段比顺序在前的数据分段传输的时间要长，如果终端设备接收到顺序在后的数据分段时，还没有接收到顺序在前的数据分段，则认为顺序在前的数据分段一定是丢失了，此时，不需要再等待顺序在前的数据分段了，故，终端设备确定RLC重组定时器的配置信息是RLC重组定时器的时长为0。
作为另一种示例，在网络设备为终端设备提供服务期间，若终端设备与网络设备之间的信号传输时延逐渐变小，则确定RLC重组定时器的时长为最大传输时延与当前传输时延的差值。
其中，该最大传输时延是网络设备在提供服务期间与终端设备之间信号传输的最大时延，该网络设备是当前为终端设备提供服务的卫星；该当前传输时延是网络设备在当前时刻与终端设备之间信号传输的时延。
示例性的，图8为终端设备与网络设备之间的信号传输时延逐渐变小的示意图。如图8的(a)所示，在当前卫星为该终端设备提供通信服务期间，随着卫星的移动，卫星逐渐靠近终端设备，即终端设备与网络设备之间的信号传输时延的变化规律为终端设备与网络设备之间的信号传输时延逐渐变小，时延与时间的曲线变化示意图参照图8的(b)所示。
对于这种情况，由于终端设备与网络设备之间的信号传输时延逐渐变小，则网络设备向终端设备传输的多个数据分段中，顺序在前的数据分段比顺序在后的数据分段传输的时间要长，如果终端设备接收到顺序在后的数据分段时，还没有接收到顺序在前的数据分段，这时可以等待一段时间，且此时等候的最长时间即顺序在后的数据分段的时延，因而，终端设备确定RLC重组定时器的配置信息是RLC重组定时器的时长为最大传输时延与当前传输时延的差值。
作为再一种示例，在网络设备为终端设备提供服务期间，若终端设备与网络设备之间的信号传输时延为非单向变化，则确定该RLC重组定时器的时长为当前最大传输时延与当前传输时延的差值。
其中，当前最大传输时延是网络设备在提供服务期间与终端设备之间已经经历过的信号传输的最大时延，网络设备为当前为终端设备提供服务的卫星，当前传输时延是网络设备在当前时刻与终端设备之间信号传输的时延。
图9为终端设备与网络设备之间的信号传输时延先变小再变大的示意图。如图9的(a)所示，在当前卫星为该终端设备提供通信服务期间，随着卫星的移动，卫星先逐渐靠近终端设备，然后再逐渐远离终端设备，即终端设备与网络设备之间的信号传输时延的变化规律为终端设备与网络设备之间的信号传输时延先逐渐变小再逐渐变大，时延与时间的曲线变化示意图参照图9的(b)所示。
可以理解的是，在本申请的实施例中，终端设备与网络设备之间的信号传输时延为非单向变化，还可以包括其他类型的变化规律，例如，先逐渐变大再逐渐变小，或者，先逐渐变大再逐渐变小，最后逐渐变大等形式。本申请实施例并不对非单向变化的具体表现形式进行限定，其可以根据实际情况确定。
对于这种情况，在终端设备与网络设备之间的信号传输时延为非单向变化时，例如，先逐渐变小再逐渐变大。在终端设备与网络设备之间的信号传输时延逐渐变小期间，网络设备向终端设备传输的多个数据分段中，顺序在前的数据分段比顺序在后的数据分段传输的时间要长，如果终端设备接收到顺序在后的数据分段时，还没有接收到顺序在前的数据分段，则可以等待一段时间，且等候的最长时 间即顺序在后的数据分段的时延；而在终端设备与网络设备之间的信号传输时延逐渐变大期间，网络设备向终端设备传输的多个数据分段中，顺序在后的数据分段比顺序在前的数据分段传输的时间要长，如果终端设备接收到顺序在后的数据分段时，还没有接收到顺序在前的数据分段，而终端此时并不知道顺序在前的数据分段是在终端设备与网络设备之间的信号传输时延逐渐变小期间发送的还是在终端设备与网络设备之间的信号传输时延逐渐变大期间发送的，因此终端可以等待一段时间。所以，终端设备确定RLC重组定时器的配置信息是RLC重组定时器的时长为当前最大传输时延与当前传输时延的差值。
类似的，当前传输时延可以根据该卫星当前所处的位置信息和终端设备的位置信息计算得到，当前最大传输时延为网络设备在提供服务期间与终端设备之间已经经历过的信号传输的所有时延中的最大值。
S603、终端设备根据RLC重组定时器的配置信息，确定RLC重组定时器的定时器信息。
在本实施例中，终端设备在确定RLC重组定时器的配置信息后，可以基于该配置信息确定出RLC重组定时器的定时器信息，例如，时长，从而达到及时调整RLC重组定时器的时长的目的，使得终端设备在满足RLC重组定时器的启动条件时，可以基于RLC重组定时器的配置信息控制RLC重组定时器的运行时长。
进一步的，在本申请的实施例中，在上述S603之后，该方法还可以包括如下步骤：
S604、终端设备根据RLC重组定时器的定时器信息，调整RLC重组定时器的时长。
关于该步骤的具体实现，可以参见图2所示实施例中S604的记载，此处不再赘述。
进一步的，在本申请的实施例中，该方法还可以包括如下步骤：
在确定RLC重组定时器满足启动条件时，启动RLC重组定时器，该启动条件为在接收到第一数据时，位于第一数据之前的至少一个比特还未被接收到，且RLC重组定时器当前未处于运行状态。
可选的，在终端设备与网络设备之间的信号传输时延逐渐变大时，终端设备可以在任何满足RLC重组定时器启动/重启时刻，启动/重启RLC重组定时器，该RLC重组定时器的时长都为0。即：终端设备在RLC重组定时器满足启动/重启条件时，不启动/重启RLC重组定时器，直接执行RLC重组定时器超时的相关操作。
可选的，在终端设备与网络设备之间的信号传输时延逐渐变小时，终端设备可以在任何满足RLC重组定时器的启动/重启时刻，启动/重启RLC重组定时器，此时，该RLC重组定时器的时长为上述最大传输时延与当前传输时延的差值。其中，当前传输时延可以根据该卫星当前所处的位置信息和终端设备的位置信息计算得到。
可选的，在终端设备与网络设备之间的信号传输时延为非单向变化时，终端设备在任何满足RLC重组定时器的启动/重启时刻，可以启动/重启RLC重组定时器，此时，RLC重组定时器的时长为当前最大传输时延与当前传输时延的差值。
可以理解的是，该S604具体实现原理与图2所示实施例中S205的实现原理类似，并且终端设备启动和/或重启RLC重组定时器的具体实现原理也类似，具体可以参见上述图2所示实施例中的记载，此处不再赘述。
本申请实施例提供的信息处理方法，终端设备在下行HARQ反馈功能和HAQR重传功能均关闭时，确定RLC实体的RLC模式，根据RLC实体的RLC模式，确定RLC重组定时器的配置信息，最后根据RLC重组定时器的配置信息，确定RLC重组定时器的定时器信息。该技术方案中，终端设备可以自行确定RLC重组定时器的配置信息，并维护和使用RLC重组定时器，使得RLC重组定时器时长能够更加准确的匹配终端设备与网络设备之间信号传输时延的变化，避免了RLC重组定时器时长配置不合适导致过早或者过晚的RLC丢包或者RLC重传，影响用户体验的问题。
综合上述各实施例，本申请实施例提供了一种信息处理方法，实际上是一种NTN中在关闭下行HARQ反馈功能且关闭HARQ重传的情况下，动态调整终端RLC重组定时器时长的方法，不管是网络设备配置终端设备侧的RLC重组定时器的信息，还是终端设备侧自行确定RLC重组定时器的信息，均能够使得终端设备侧的RLC重组定时器的时长能够很好的匹配终端设备与网络设备之间信号传输时延的变化，使用该方法维护的RLC重组定时器，可以避免由于RLC重组定时器的时长配置不合适导致过早或者过晚的RLC丢包或者RLC重传问题，提高了用户的业务体验。
