Abstract

本发明实施例公开一种资源池配置方法及设备、计算机存储介质;方法包括:配置物理边链路第二控制信道(PSSCCH)资源池;所述PSSCCH资源池中的资源用于供进行设备到设备(D2D)通信的用户设备(UE)承载发送物理边链路的反馈控制信息。

Description

资源池配置方法及设备、计算机存储介质 技术领域
本发明涉及移动通信技术,尤其涉及到一种设备到设备(D2D,Device-to-Device)通信中资源池配置方法及设备、计算机存储介质。
背景技术
在D2D通信系统中,用户设备(UE,User Equipment)之间有业务需要传输时,UE之间的业务数据不经过基站的转发,而是直接由数据源UE通过空中接口传输给目标UE,如图1所示,D2D UE之间的无线链路称为边链路(Sidelink),D2D通信模式具有明显区别于传统蜂窝系统通信模式的特征,对于能够应用D2D通信方式的近距离通信用户来说,D2D传输不但节省了无线频谱资源,而且降低了核心网的数据传输压力,能够减少系统资源占用,增加蜂窝通信系统频谱效率,降低终端发射功耗,并在很大程度上节省网络运营成本。
在传统的蜂窝通信系统中,UE的无线资源由演进型基站eNB(evolved NodeB)统一控制调度,eNB指示UE所配置的下行或上行资源,UE按照eNB的配置指示在相应的下行资源上接收eNB发射的数据信号,或者在上行资源上向eNB发射信号。在LTE系统中,无线资源在时域上以无线帧为单位划分资源,每个无线帧为10ms,包含10个子帧。每个子帧为1ms,分为0.5ms的2个时隙slot,如图2所示,在频域上,以子载波为单位划分资源,每个子载波包含15kHz或7.5kHz资源。按照上述时域和频域资源单位,eNB为UE调度时频资源的最小单位为资源块RB(Resource Block),RB定义为在时域上为1个slot,在频域上为连续的
Figure PCTCN2015092085-appb-000001
个子载波,
Figure PCTCN2015092085-appb-000002
如图3所示,eNB可以灵活地根据UE需求动态调度配置所需的资源。
在D2D通信系统中,UE之间直接进行数据的传输,发送端UE可以按照网络侧的调度配置获得D2D通信的物理边链路控制信道(PSCCH,Physical Sidelink Control Channel)和物理边链路共享信道(PSSCH,Physical Sidelink Shared Channel)资源,也可以在给定的PSCCH和PSSCH资源池中竞争选择资源进行D2D通信控制及数据信息的发射;
但在上述D2D通信过程中存在以下问题:基于PSCCH和PSSCH资源,D2D UE仅能够进行单向的广播/组播通信,发送端UE对D2D数据进行盲发射,不能获知数据接收的情况,且信道资源利用率低。
发明内容
本发明实施例提供一种资源池配置方法及设备、计算机存储介质,能够提高物理边链路信道资源利用率。

上述确定PSSCCH资源池的方法在不冲突的条件下可以任意组合使用,下面通过具体示例来进一步说明。
基于PSSCCH资源池配置,可以达到有效的反馈D2D控制信息的作用,一个实例如图5所示,eNB通过高层信令配置指示PSSCCH资源池,小区内的D2D UE都可以获得统一的PSSCCH资源池配置信息,当D2D发射端UE(Tx UE)在PSCCH资源上发送D2D调度控制信息后,D2D接收端UE(Rx UE)根据控制信息在相应的PSSCH资源上接收D2D数据,进一步的,Rx UE可以将接收D2D data的反馈信息和/或Sidelink信道测量报告等反馈控制信息承载在PSSCCH资源上向Tx UE反馈。
示例一 系统定义
D2D通信系统中,在不同的系统带宽(或D2D通信可用带宽)和系统双工方式下,可相应定义系统中PSSCCH资源池中包含的资源。一个实施 例如表1所示,在不同的系统带宽及双工方式下,定义固定的PSSCCH资源池配置,每一种PSSCCH资源池的配置定义中,包含PSSCCH资源池的周期,在周期内包含的子帧,以及每个PSSCCH子帧上包含的RB资源。例如PSSCCH配置#FDD-5定义为:PSSCCH资源池周期40ms,周期内包含4个PSSCCH子帧,分别为子帧#9/19/29/39,PSSCCH资源池中包含的频域RB为RB index#0/1/2/3/4以及RB index#RBUL-5/RBUL-4/RBUL-3/RBUL-2/RBUL-1,RBUL表示系统频域RB数量,其他的PSSCCH资源池配置如#FDD-10、#FDD-15、#TDD 0-5等可类似定义。

表1
当系统定义固定的PSSCCH资源池在不同的系统带宽及双工方式下的具体配置时,系统中的D2D UE可以根据系统带宽和双工方式确定相应的PSSCCH资源池配置,不需要信令对PSSCCH资源池进行指示,可以降低配置信令指示开销,统一PSSCCH资源池配置。
示例二 系统预配置
D2D通信系统中,由系统预配置PSSCCH资源池,通过网络侧设备下发到全网,或根据运营商需求在网络侧和终端设备中进行预配置。当系统采用预配置的PSSCCH资源池时,可通过相应的参数设置PSSCCH资源池,具体的参数包括:周期period,PSSCCH子帧位图指示bitmap,偏移指示offset,RB数量指示RB-number,RB起始位置指示RB-start,RB截止位置指示RB-end,通过上述参数指示PSSCCH资源池的指示效果如图6所示,其中,offset指示PSSCCH子帧bitmap相对于周期边界的偏移起始位置,从offset指示对应的子帧开始映射bitmap,相应bit位指示为“1”时,表示对应的子帧为PSSCCH子帧,相应bit位指示为“0”时,表示对应的子帧不是PSSCCH子帧。频域上,从RB index=RB-start开始的RB-number个连续的RB,以及从RB index=RB-end向内的RB-number个连续的RB为PSSCCH资源池在频域上包含的资源。
通过系统预配置PSSCCH资源池,可以有效根据网络需求来配置相应的PSSCCH资源池中的资源,达到充分利用系统资源,协调干扰,提高资源利用率的效果。
示例三 高层信令指示,bitmap循环重复
D2D通信系统中,由系统通过高层信令,如系统广播信息(系统信息块)SIB信令,指示配置的PSSCCH资源池,通过SIB指示的PSSCCH资源池配置对小区内所有D2D UE有效,或者可以针对不同群组的D2D UE设置共用的PSSCCH资源池。与示例二中的配置参数类似,当系统通过SIB信令指示PSSCCH资源池时,可通过:周期period,PSSCCH子帧位图指示bitmap,偏移指示offset,RB数量指示RB-number,RB起始位置指示RB-start,RB截止位置指示RB-end指示PSSCCH资源池。其中,PSSCCH子帧bitmap可以在周期内循环重复映射,直至周期的末尾,另外,当bitmap 在周期内的最后一次映射与周期内的子帧数量不相同时,bitmap映射按照实际可用子帧进行截短,如图7所示。
通过高层信令指示PSSCCH资源池配置,可以有效根据网络需求来配置相应的PSSCCH资源池中的资源,并具备一定的灵活性,可以在一定的时间范围内对PSSCCH资源池配置进行调整,达到充分利用系统资源,协调干扰,提高资源利用率的效果。
示例四 由PSCCH资源池确定PSSCCH子帧
D2D通信系统中,PSSCCH资源池中包含的子帧由PSCCH资源池中包含的PSCCH子帧确定。
PSSCCH资源池的周期与PSCCH资源池周期相同,且PSSCCH子帧由PSCCH子帧索引确定,即PSSCCH子帧与PSCCH子帧一一对应,且PSSCCH子帧与相应的PSCCH子帧之间的子帧间隔k,其中,k为整数,可由系统设置为常数值,或者由高层信令指示,例如通过SIB信令指示k的取值。
如图8所示,在一个周期内,PSCCH资源池中包含4个PSCCH子帧,且系统设置k=8,则相应可以确定PSSCCH资源池中也包含4个PSSCCH子帧,分别位于与PSCCH相应子帧间隔为8的子帧位置。
根据PSCCH资源池中的子帧配置索引确定PSSCCH资源池中的子帧配置,不需要信令指示,达到灵活的配置PSSCCH资源池,适应于业务需求,降低信令开销的作用。
示例五 由PSSCH资源池确定PSSCCH子帧,n:1关系
