Description

一种调度请求资源确定及配置方法、设备及存储介质
相关申请的交叉引用
本申请要求在2018年08月16日提交中国专利局、申请号为201810934283.5、申请名称为“一种调度请求资源确定及配置方法、设备及装置”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
本申请涉及无线通信技术领域,特别涉及一种调度请求资源确定及配置方法、设备及存储介质。
背景技术
首先对长期演进(Long Term Evolution,LTE)系统调度请求(Scheduling Request,SR)机制介绍如下:
LTE系统是基于调度的系统,由基站为终端设备分配数据传输所需的时频资源,终端根据基站的调度命令进行下行数据接收或者上行数据发送。上行数据传输是由基站调度的,基站调度器确定上行资源分配情况之后会通过上行调度许可(UL grant)通知终端。基站调度器进行上行资源分配的依据是终端要发送的上行数据量,即终端的缓存状态。该缓存在终端,基站要想获知该信息,就需要终端向基站进行缓存状态上报(Buffer status report,BSR)。LTE Rel-11及之前版本中BSR分类以及触发机制如下:
常规(Regular)BSR:(1)当有比当前缓存(buffer)中的数据更高优先级的数据到达或原本为空的buffer中有数据到达时触发;(2)retxBSR-Timer超时且缓存中有数据时触发。
周期性(Periodic)BSR:periodicBSR-Timer超时时触发Periodic BSR。
捎带(Padding)BSR:如果用户设备(User Equipment,UE)在组织媒质接入控制协议数据单元(Medium Access Control,MAC)协议数据单元 (Protocol Data Units,PDU)的时候,除了需要传输的数据外还有资源可用,可以触发Padding BSR。
当终端有Regular BSR触发(触发Regular BSR的逻辑信道未配置SR禁止(masking)),但是终端没有UL grant,则会触发SR。
触发SR后,发送SR的方式有两种,即:通过专用调度请求资源发送SR(D-SR)和通过随机接入过程来进行SR(RA-SR)。
专用SR(D-SR):D-SR由无线资源控制(Radio Resource Control,RRC)分配,由物理上行控制信道(Physical Uplink Control Channel,PUCCH)承载。
随机接入SR(RA-SR):利用随机接入过程来发送SR。
SR发送的基本原则是:只要有D-SR资源,就不使用RA-SR。只有当没有D-SR资源配置时,才会使用RA-SR。
下面对新空口(New Radio,NR)系统SR介绍如下:
NR系统物理层支持多numerology/TTI。基带参数(numerology)和传输时间间隔(Transmission Time Interval,TTI)的概念分别如下:
Numerology是3GPP RAN1的一个专业术语,可以翻译为基带参数。不同numerology之间的主要区别是不同numerology支持的子载波间隔(Sub-carrier Spacing,SCS)不同。比如5G NR系统支持的子载波间隔至少包括:15KHz、30kHZ、60KHz、120kHz,不同子载波间隔对应的numerology是独立的numerology。一般而言,高速终端使用的numerology和低速终端使用的numerology不同;高频和低频使用的numerology也不相同。不同numerology的使用除了和速度以及频率相关外,业界还有一种理解就是不同业务可以使用的numerology也可能不同,比如高可靠性与超低时延(Ultra Reliable & Low Latency Communication,URLLC)和增强型移动互联网(Enhanced Mobile Broadband,eMBB)使用的numerology可能不同。
TTI即传输时间间隔。传统的LTE系统中,TTI长度为1ms。从LTE R14开始,为了支持时延缩减,引入了不同TTI长度,比如1个正交频分复用(Orthogonal Frequency Division Multiplex,OFDM)符号长度。不同TTI长度 在5G系统中得到沿用并可以应用于每个numerology上,即5G NR中不同numerology可以使用不同TTI长度,也可以使用相同TTI长度,并且任何一个时刻某个numerology上针对不同终端使用的TTI长度可以是动态变化的。TTI长度的选择主要和业务时延相关,比如对于URLLC业务因为其支持的时延要求比较高,所以可能会选择长度较短的TTI长度,比如1个OFDM符号的TTI长度。
对于NR系统,一个承载/逻辑信道对应的numerology和/或TTI是通过网络配置的。不同逻辑信道对应的numerology和/或TTI可以相同或者不同。对于上行,SR信息需要能够反映当前有数据传输需求的逻辑信道对应的numerology和/TTI,这样网络侧设备才能根据SR为终端进行合理的上行资源分配,为了实现这一目标,NR的设计思路是:
引入多套SR配置(SR configuration),网络侧配置终端各个逻辑信道和SR配置的对应关系,同时网络侧配置逻辑信道和numerology/TTI的对应关系;
终端有SR触发,则根据触发SR的逻辑信道、网络侧配置的逻辑信道和SR配置的对应关系,选择SR发送使用的SR配置进行SR发送;
网络侧接收到SR,则根据网络侧配置的逻辑信道和SR配置的对应关系确定有数据需要发送的逻辑信道,然后确定UL grant对应的numerology和/或TTI,进行合理调度。这些SR配置分别映射到不同的PUCCH资源中(不同PUCCH资源指的是PUCCH占用的时/频域资源不同)。
现有技术的不足在于,NR系统引入了多套SR配置,对于Uu接口链路(Uu link),逻辑信道是网络配置的,网络会为终端配置每个逻辑信道和SR配置的映射关系,这样当终端有SR触发,终端首先确定是哪个逻辑信道触发了SR,然后根据触发SR的辑信道以及逻辑信道和SR配置的映射关系确定终端要使用的SR配置。
对于直接通信/直通链路(Sidelink),和Uu link不同,Sidelink的逻辑信道是终端自行建立的,因当终端的Regular Sidelink BSR触发SR,终端不知道应该选择哪套SR资源发送。

具体实施方式
NR系统引入了多套SR配置,对于Uu link,逻辑信道是网络配置的,网络会为终端配置每个逻辑信道和SR配置的映射关系,这样当终端有SR触发,终端首先确定是哪个逻辑信道触发了SR,然后根据触发SR的辑信道以及逻辑信道和SR配置的映射关系确定终端要使用的SR配置。
对于Sidelink,和Uu link不同,Sidleink的逻辑信道是终端自行建立的,因当终端的Regular Sidelink BSR触发SR,终端不知道应该选择哪套SR资源发送。基于此,本申请实施例中给出了直接通信接口调度请求资源确定方案,主要用于解决Sidelink链路上Regular BSR触发的SR资源选择问题。本申请实施例中给出的方案主要为:网络侧配置直接通信接口(Sidelink接口)服务 质量(Quality of Service,QoS)参数/QoS参数组合和Uu接口SR资源之间的映射关系。然后终端在Sidelink接口Regular BSR触发SR后,终端根据触发Regular BSR的Sidelink接口的QoS参数在Uu口选择合适的SR资源进行发送。
下面结合附图对本申请的具体实施方式进行说明。
在说明过程中,将分别从终端与基站侧的实施进行说明,其然后还将给出二者配合实施的实例以更好地理解本申请实施例中给出的方案的实施。这样的说明方式并不意味着二者必须配合实施、或者必须单独实施,实际上,当终端与基站分开实施时,其也各自解决终端侧、基站侧的问题,而二者结合使用时,会获得更好的技术效果。
图1为网络侧的配置SR发送资源的方法实施流程示意图,如图所示,可以包括:
步骤101、网络侧配置Sidelink接口的QoS参数和Uu接口SR资源的映射关系;
步骤102、网络侧将所述映射关系通知终端,所述映射关系用以供终端确定发送SR的资源。

图2为终端的SR的资源确定方法实施流程示意图,如图所示,可以包括:
步骤201、终端接收网络侧配置的直接通信Sidelink接口的QoS参数和Uu接口调度请求SR资源的映射关系;

这样终端就可以在确定的SR资源上向网络侧发送SR了。
