Abstract

Description

一种信息接收方法、信息发送方法、装置及可读存储介质
相关申请的交叉引用
本公开主张在2022年4月20日在中国提交的中国专利申请号No.202210419061.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种信息接收方法、信息发送方法、装置及可读存储介质。
背景技术
相关技术的通信网络架构设计中,基站通常是中心控制节点,终端通过接收基站的指令执行相应的操作,所述操作包括小区接入和资源调度等。所述小区接入,其主要目的如下:1)建立上行链路同步;2)建立一个唯一终端标识,如小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI),请求网络分配给终端上行链路资源。所以小区接入不仅用于初始化接入,而且还可以用于切换过程中的新小区接入、无线链路失败后的接入、在有上/下行数据传输时重新恢复上行同步以及上行共享信道(Uplink Shared Channel,UL-SCH)资源请求等。所述资源调度,包括终端向网侧申请资源用于新数据传输。调度请求(Scheduling Request,SR)属于物理层的信息,用户设备(User Equipment,UE)发送SR不需要资源块(Resource block,RB)资源,通过物理上行控制信道(Physical uplink control channel,PUCCH)传输。网络侧成功解码到某个终端的SR信号之后,可能会通过下行控制指示0(Downlink Control Indication 0,DCI0)给该终端分配RB资源,也可能不会分配,终端不应该假设网络侧的结果。很多时候,终端为了得到上行RB资源,需要多次发送SR申请。
上述终端接入基站过程中的交互方式不够灵活。随着科技的日益发展,越来越多的移动中的终端(包括手机终端或其他机器设备),尤其是高速移动的终端,可能需要通过频繁的接入获得服务,已越来越影响到终端接入的性能和终端的用户体验。

具体实施方式
本公开实施例中术语“和/或”,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。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
长期演进(long Term Evolution,LTE)系统上行链路随机接入过程采用非同步的接入方式,即在终端还未获得上行时间同步或丧失同步时,用于基站(the next Generation Node B,gNodeB)估计、调整UE上行发射时钟的过程,这个过程也同时用于UE向gNodeB请求资源分配。gNodeB响应UE的非同步随机接入尝试,向UE发送时间信息来调整上行链路发送定时,并分配所传送数据或控制信令的上行链路资源,而且定时信息和上行数据资源分配也可以组合在一起发送到UE。随机接入过程有两种模式:(1)基于竞争的随机接入;(2)无竞争的随机接入。每个小区中有64个可用的前导序列,对于基于竞争的随机接入过程来说,UE随机选择一个前导序列向网络侧发起随机接入过程,因此如若同一时刻多个UE使用同一个前导序列发起随机接入过程,就会发生冲突,有可能导致接入失败。而无竞争的随机接入使用gNodeB所分配的前导序列发起随机接入过程,故接入成功率较高。但考虑到仅在切换或有下行数据发送两个场景下,gNodeB能够事先知道UE需要发起随机接入过程,所以仅在这两个场景可以使用无竞争的随机接入,对于其他应用场景,只能使用基于竞争的随机接入。
与LTE类似,新空口(New Radio,NR)系统中的随机接入总体上也分为两类,基于竞争的随机接入(Contention Based Random Access,CBRA)和基于非竞争的随机接入(Contention Free Random Access,CFRA)。
进一步的,关于调度请求信息,当UE触发了一个调度请求(Scheduling Request,SR)时,该SR就处于待定(Pending)态,表示UE准备但还没有向网侧发送SR。当UE已经组装了一个媒体接入控制协议数据单元(Media  Access Control Protocol Data Unit,MAC PDU),并且该PDU包含了最近触发的缓存状态报告(Buffer Status Report,BSR)控制单元,或者上行授权提供的资源可以容纳所有待传的数据,那么处于Pending态的SR就会被取消,同时禁止定时器sr-ProhibitTimer也会被停止。换句话说,如果已经准备发送BSR,或者当前的资源块(Resource Block,RB)资源已经足够,就没有必要再通过SR申请资源了。
相关技术中,没有基于移动的灵活网络结构下的接入节点的解决方案,例如,针对移动的接入节点如何接入网络,也没有进一步的讨论。
相关技术中,通过多个信息的交互过程获取相关信息,可能带来较大的网络时延,尤其对于灵活小区(如移动式基站的小区)而言,终端和基站的高速移动,可能会带来频繁的切换和大量的交互过程,甚至会带来较大的信令风暴,进一步造成网络拥塞。
基于此,本公开实施例提供了一种信息接收方法、信息发送方法、装置及可读存储介质,用以接入节点间的信息交互灵活性差的问题,提高接入节点间信息交互的灵活性。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
