Description

一种资源分配的方法和装置 技术领域
本发明涉及设备到设备(D2D,Device-to-Device)通信领域,尤其涉及一种资源分配的方法和装置。
背景技术
在蜂窝系统中,当两个用户设备(UE,User Equipment)之间有业务需要传输时,用户设备1(UE1)到用户设备2(UE2)的业务数据,会首先通过空口传输给UE1所在小区的基站(Base Station,或者称为演进型基站(eNB,evolved eNB)),该基站通过核心网将该业务数据传输给UE2所在小区的基站,该基站再将上述业务数据通过空口传输给UE2。UE2到UE1的业务数据传输采用类似的处理流程。
而实际上,随着移动通信业务的多样化,例如,社交网络、电子支付等在无线通信系统中的应用越来越广泛,使得近距离用户之间的业务传输需求日益增长。因此,设备到设备(D2D,Device-to-Device)的通信模式日益受到广泛关注。所谓D2D,是指业务数据不经过基站进行转发,直接由源用户设备通过空口传输给目标用户设备,也可称之为邻近服务(ProSe,Proximity Service)。这种通信模式区别于传统蜂窝系统的通信模式。对于近距离通信的用户来说,D2D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。
在LTE Release 12中标准化的D2D通信为广播通信,且根据是否有基站的参与,D2D通信分为两种模式:
通信模式一(Mode 1communication),是指eNB调度Tx UE(发送方UE)进行D2D数据传输(D2D data transmission),即Tx UE传输的每一个 D2D数据包资源(D2D data packet resource)都由eNB配置指示,Tx UE与eNB建立无线资源控制(RRC,Radio Resource Control)连接后,可以在eNB的统一调度下进行Mode 1communication;
通信模式二(Mode 2communication),是指在给定的资源池(resource pool)中,D2D Tx UE自主竞争选择资源,进行D2D data transmission。
现有标准中规定在一个PSCCH(Physical Sidelink Control Channel)周期只能发送一个调度分配(SA,Scheduling Assignment)信息用来指示其数据资源的发送位置信息,不支持一个PSCCH周期对多个SA的发送;其中,Sidelink为D2D通信的UE之间所建链路,PSCCH为基于Sidelink链路的物理控制信道,该信道上用于发送D2D通信的控制调度信息。也就是说按照现有标准规定,D2D UE在一个PSCCH周期内只能服务一个UE。
在LTE Release 13中增加了D2D中继(D2D relay)和多组增强通讯,所谓D2D Relay是指在覆盖内UE(即eNB覆盖范围内的UE)移动导致UE和eNB之间信道恶化时,为了保证服务的连续性,基站将会选择通过Relay UE继续和远端UE(Remote UE)连接;在无覆盖场景下,Relay UE充当覆盖外UE(即eNB覆盖范围外的UE)与eNB连接的桥梁。
在D2D场景下,为满足D2D通信对业务时延的约束,D2D UE有在一个PSCCH周期内同时服务多个UE的需要,例如:一个D2D Relay UE在一个PSCCH周期需要发送两个SA信息,一个用于Relay包的发送、另一个用于其自身广播或单播的发送,再例如:D2D UE自身在一个PSCCH周期也有需要发送两个SA信息,一个用于广播发送、另一个用于单播发送。也就是说,从应用场景来看,D2D UE存在在一个PSCCH周期内同时服务多个UE的需求。然而现有技术并未给出在D2D场景下,D2D UE(其中包括D2D Relay UE)在一个PSCCH周期内能够同时服务多个UE的解决方案,这无疑会限制D2D通信的发展。

具体实施方式
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
本发明实施例一提供的一种资源分配的方法,如图1所示,该方法主要包括:
步骤101,第一UE接收基站下发的调度授权指示信息,所述调度授权 指示信息所指示的资源为所述基站为所述第一UE配置的对N个第二UE的发送资源、或所述调度授权指示信息所指示的资源为所述第一UE指示的N个第二UE的发送资源。
本发明实施例所述的第一UE可以是D2D relay UE,也可以是同时支持多发的D2D UE。也就是说,本发明实施例所述的第一UE能够支持同时为N个第二UE服务。
其中,所述第二UE通过所述第一UE向基站请求资源(第二UE向第一UE发送数据的资源)时,所述第一UE接收的调度授权指示信息所指示的资源为所述第一UE指示的N个第二UE的发送资源;所述第一UE向基站请求资源(指示为N个第二UE)时,所述第一UE接收的调度授权指示信息所指示的资源为所述基站为第一UE配置的对N个第二UE的发送资源。
步骤102,所述第一UE基于收到的所述调度授权指示信息进行针对所述第二UE的资源分配,或者,所述第一UE基于收到的所述调度授权指示信息向第二UE指示所述第二UE的资源;
其中,N为大于等于1的整数;所述资源至少包括PSCCH资源和PSSCH(Physical Sidelink Share Channel)资源,所述PSCCH为Sidelink链路的物理控制信道,所述PSSCH为Sidelink链路物理共享信道,所述Sidelink链路为设备到设备D2D通信的UE之间所建链路。
其中,所述调度授权指示信息指示所述PSCCH的时域资源对应的索引号x,且所述调度授权指示信息隐含的指示N个第二UE的PSCCH的时域资源所在的索引号为:包括所述索引号x在内的频率连续的N个PSCCH的时域资源的索引号。
也就是说,基站利用Sidelink调度授权向第一UE指示PSCCH的时域资源所在的索引和data(业务数据)的时频域资源;第一UE按照基站的指 示,在相应的时频资源上发送SA和data,其中,PSCCH的时域资源隐含N个第二UE的时域资源所在的索引号,其隐含索引号为上行调度授权中指示的SA时域资源所在的索引号及其频率连续N个SA时域资源所在的索引号。其中,隐含的用户数N可以为第一UE已知,或者也可以为基站通过Sidelink调度授权信令指示;基站Sidelink调度授权data的时频资源为N个用户(第二UE)的资源。
在一实施方式中,所述第一UE基于收到的调度授权指示信息进行针对第二UE的资源分配,包括:
将不同的所述第二UE的PSSCH资源分配在不同的子帧或分配在同一子帧上连续的频域位置。
在一实施方式中,所述第一UE基于收到的调度授权指示信息进行针对第二UE的资源分配,包括:
在所分配的PSCCH资源中,所述第一UE在N个PSCCH资源上发送N个第二UE的资源调度信息,配置的子帧在重发时如果存在N个用户在同一子帧的情况,则根据所述第一UE和第二UE之间的参考信号接收功率(RSRP),只保留RSRP最低的重发资源的分配。例如:配置的子帧在重发时如果存在两个用户在同一子帧的情况,则根据测量所得第一UE和第二UE之间的RSRP,只保留RSRP相比较低的用户的重发资源的分配,取消RSRP相比较高的用户的重发资源的分配。再例如:配置的子帧在重发时如果存在三个用户在同一子帧的情况,则根据测量所得第一UE和第二UE之间的RSRP,只保留RSRP最低的用户的重发资源的分配,取消另外两个RSRP稍高的用户的重发资源的分配。
在一实施方式中,在所述第一UE接收基站下发的调度授权指示信息之前,所述方法还包括:
所述第一UE向基站发送资源请求,所述请求中至少包括所述第一UE 请求调度的第二UE的数量M和PSSCH资源需求;
其中,所述基站下发的调度授权指示信息中指示的第二UE的数量N与所述M相同或不同。

实施例五
本发明实施例五的应用场景可以参见图6,覆盖内UE A为覆盖外的UE B、UE C、UE D提供Relay服务,此时的UE A称为D2D Relay UE。实施例五的具体实施过程包括:
1)多个远端UE(如UE B、UE C、UE D)向D2D Relay UE提出资源请求,或D2D UE A自身有通讯需求(此时的UE A称为同时支持多发的UE A),或D2D Relay UE根据需求向多个UE转发基站data;
2)D2D Relay UE或同时支持多发的UE A向eNodeB发送D2D资源请求;
3)eNodeB通过为D2D Relay UE或同时支持多发的D2D UE配置发送资源,如通过物理下行控制信道(PDCCH,Physical Downlink Control Channel)或增强型物理下行控制信道(EPDCCH,Enhanced Physical Downlink Control Channel)下发,为D2D Relay UE或同时支持多发的UE配置所需的PSCCH index(索引)和其所需的D2D data transmission的相关 控制信息及资源配置信息。其中,配置信息指示的资源可以是Mode1或Mode2的资源池,由eNodeB进行选择。如D2D Relay UE或同时支持多发的UE请求服务两个D2D UE,其PSCCH index=0,其data transmission的相关控制信息包括下发两个UE的data transmission的控制信息。如下表1所示,DCI format 5,SCI指示所服务的两个UE的数据资源的控制信息,SA resource index指示所配置的PSCCH时域和频域资源,如图5和图7所指示的index。
Figure PCTCN2016079150-appb-000003
表1
其中,D2D Relay UE或同时支持多发的UE接收PDCCH或EPDCCH,如index=0,其要求的资源为2个用户,则默认物理资源块(PRB,Physical Resource Block)连续的下一个资源也是分配给Relay UE或同时支持多发的UE的,即index=0、index=4的PSCCH资源可以作为Relay UE服务两个UE的PSCCH资源,即index=0的资源用于D2D Relay UE或同时支持多发的UEA向UE B发送PSCCH,index=4的资源用于D2D Relay UE或同时支持多发的UEA向UE C发送PSCCH,并通过SCI指示根据基站配置的data transmission资源的一部分用于UE B,一部分用于UE C;
对于D2D UE A自身有通讯需求(此时的UE A称为同时支持多发的UE A),或D2D Relay UE根据需求向多个UE转发基站data的情形,其基站配置的data transmission资源由D2D Relay UE或同时支持多发的UE A根据频域连续或子帧正交的原则、通过PSCCH指示在相应的资源上发送给用 户B和用户C。而接收对于远端UE请求发送的D2D Relay UE仅根据基站调度信息指示的index=0,在index=0的PSCCH上发送用于远端UE B的调度信息、以及在index=4的PSCCH上发送用于远端UE C的调度信息;而远端UE B和UE C根据接收D2D Relay UE的PSCCH解析的调度信息在相应的资源上发送数据。
如果index=0,其要求的资源为3个用户,则默认PRB连续的下两个资源也是分配给自己的,即index=0、index=4、index=8的PSCCH资源可以作为Relay UE服务三个UE的PSCCH资源,即index=0的资源用于UE B的发送,index=4的资源用于UE C的发送,index=8的资源用于UE D的发送,并通过SCI指示根据基站配置的data transmission资源的一部分用于UE B,一部分用于UE C,一部分用于UE D,其两个用户的PSSCH位于不同子帧如图9,或同一子帧的连续PRB上如图10,即UE B的endPRB+1为UE C的startPRB。
另外,D2D UE A自己有通讯需求,根据SCI指示在相应的资源发送data信息。
还存在另一种应用场景,多个远端UE向D2D Relay UE提出通讯请求,D2D Relay UE发送UE B、UE C、UE D的控制信息(D2D Relay UE向基站请求为UE B、UE C、UE D分配发送资源,即基站通过D2D Relay UE为UE B、UE C、UE D配置资源),D2D Relay UE不在所述控制信息指示的相应位置发送data,而UE B、UE C、UE D根据解析的控制信息在其SCI指示的位置发送data。
4)UE B和UE C或加上UE D解析index=0和index=4或加上index=8的信道获知其data transmission资源,转发基站信息的D2D Relay UE或D2D UE A自己有通讯需求,UE B、UE C、UE D检测PSCCH根据解析SCI信息在指定的资源上接收data。多个远端UE向D2D Relay UE提出通讯请求, UE B、UE C、UE D根据解析的PSCCH,其指示的位置UE B、UE C、UE D在相应的资源发送data。
如果Relay UE A或同时支持多发的UE A请求的用户数大于或等一个SA周期的子帧数,如图5,请求支持的用户数是4,频率连续分配的资源为4个PRB,即index=0、index=4、index=6、index=12,其重发资源在一个子帧上如果此时频域资源不连续,如index=0和index=12频域不连续,为了保证上行单载波特性,可以根据用户上报的RSRP,将链路质量较好的用户放在index=0或index=12位置资源,其重发时可以选择不发送,如UE C用户与UE A之间的链路质量最优,UE A将UE C的PSCCH调度在index=0的资源上,在重发时即第二个子帧index=0不发送。
实施例六
实施例六的具体实施过程包括:
1)多个远端UE向D2D Relay UE提出资源请求,或D2D UE A自身有通讯需求,或D2D Relay UE根据需求向多个UE转发基站data;
2)对D2D Relay UE或同时支持多发的UE A向基站发送请求;请求信息包括至少包括可支持的远端用户数目,和根据需求需要申请的资源大小。
2)eNodeB通过为D2D Relay UE或同时支持多发的UE A配置发送资源PSCCH信道资源指示及数据资源,如通过PDCCH或EPDCCH下发。其配置至少包括为Relay UE或同时支持多发的UE所需的控制资源的PSCCH index和其所需的D2D data transmission的相关资源信息和根据需要发送的配置资源服务的用户数UE Numbers。如Relay UE或同时支持多发的UE支持服务三个D2D UE,而基站调度器仅为其配置两个PSCCH资源,需要指示配置资源的用户数(UE Numbers),参见下表2,其data transmission的相关控制信息(SCI)包括下发两个UE的data transmission的时频资源指示信息。
Figure PCTCN2016079150-appb-000004
表2
其中,UE Numbers的bit位数可以根据支持的用户数进行扩展,表2所示的2bit可以最大支持4个用户。
3)D2D Relay UE A或同时支持多发的UE A接收PDCCH或EPDCCH,如index=0,且UE Numbers为2个用户,则默认SA资源的index指示的PSCCH信道的下一个连续的PSCCH信息也是分配给D2D Relay UE A或同时支持多发的UE A的,即index=0、index=4的PSCCH资源可以作为Relay UE服务两个UE的PSCCH资源,即index=0的资源用于D2D Relay UE A或同时支持多发的UE A向UE B的发送PSCCH,index=4的资源用于D2D Relay UE或同时支持多发的UE A向UE C的发送PSCCH,并将解析的SCI指示的基站为转发基站data的D2D Relay UE或同时支持多发的UE A配置的data transmission资源的一部分用于转发基站data D2D Relay UE或同时支持多发的UE A向UE B发送data,一部分用于转发基站data D2D Relay UE或同时支持多发的UE A向UE C发送data。其向两个用户发送的data通过PSCCH指示将通过D2D Relay UE或同时支持多发的UE A分配位于不同子帧如图9,或同一子帧的连续PRB上如图10,即UE B的endPRB+1为UE C的startPRB。而接收对于远端UE请求发送的D2D Relay UE仅根据基站调度信息指示的index=0,在index=0的PSCCH上发送用于远端用户UE B的调度信息、以及在index=4的PSCCH上发送用于远端用户UE C的调度信息,而远端用户UE B和UE C根据接收D2D Relay UE的PSCCH 解析的调度信息在相应的资源上发送数据。
如果index=0,其且UE Numbers为3,则默认PRB连续的下两个资源也是分配给自己的,即index=0,index=4,index=8的PSCCH资源可以作为D2D Relay UE服务三个UE的PSCCH资源,即index=0的资源用于UE B的控制信息发送,index=4的资源用于UE C的控制信息发送,index=8的资源用于UE D的控制信息发送,根据基站配置SCI指示的data transmission资源的一部分用于UE B,一部分用于UE C,一部分用于UE D。
另外,D2D UE A自己有通讯需求或向多个远端UE转发基站的信息的D2D Relay UE,根据PSCCH指示在相应的资源发送data信息。
还存在另一种应用场景,多个远端UE向D2D Relay UE提出通讯请求,D2D Relay UE发送UE B、UE C、UE D的控制信息(D2D Relay UE向基站请求为UE B、UE C、UE D分配发送资源,即基站通过D2D Relay UE为UE B、UE C、UE D配置资源),D2D Relay UE不在所述控制信息指示的相应位置发送data,而UE B、UE C、UE D根据PSCCH解析的控制信息在其指示的位置发送data。
4)UE B和UE或加上UE D解析index=0和index=4或加上index=8的信道获知其data transmission资源,转发基站信息的D2D Relay UE或D2D UE A自己有通讯需求,UE B、UE C、UE D根据PSCCH指示解析SCI信息在指定的资源上接收data。多个远端UE向D2D Relay UE提出通讯请求,UE B、UE C、UE D检测PSCCH并根据解析的SCI,其指示的位置UE B、UE C、UE D在相应的资源发送data。
如果D2D Relay UE A或同时支持多发的UE A请求的用户数大于或等一个SA周期的子帧数,如图5,请求支持的用户数是4,频率连续分配的资源为4个PRB,即index=0、index=4、index=8、index=12,其重发资源在一个子帧上如index=0和index=12为了保证上行单载波特性,可以根据 用户上报的RSRP,将链路质量较好的用户放在index=0或index=12位置资源,其重发时可以选择不发送,如UE C用户与UE A之间的链路质量最优,UE A将UE C的PSCCH调度在index=0的资源上,在重发时即第二个子帧index=1不发送。
实施例七
无覆盖场景,支持多发的D2D UE A自主选择资源,实施例七的具体实施过程包括:
1)支持多发的D2D UE A随机选择Mode 2资源池的资源,选择原则是选择SA资源池同一子帧连续的SA资源作为其发送给每个远端UE的控制信道PSCCH,在每个PSCCH中给其服务的每个用户指示其data的调度信息,如资源指示等,其向多个用户的发送的data资源可以是在频率上连续的PRB,频域不连续的PRB在时域子帧需保证正交。
如支持多发的D2D UE A需要服务两个D2D UE,随机选择连续SA资源池连续的PSCCH资源分配给其服务的两个UE,如选择index 4、index 8作为UE B、UE C的PSCCH,并分配两个用户的PSSCH位于不同子帧如图9,或同一子帧的连续PRB上如图10,即UE B的endPRB+1为UE C的startPRB。
D2D UE A,根据随机选择的PSCCH及PSSCH资源在PSCCH上发送D2D UE B和D2D UE C的控制信息,并在其指示的资源位置上进行数据通讯。其两个用户的资源指示是其选择的PSSCH资源按在频率上连续的PRB,频域不连续的PRB在时域子帧需保证正交的原则分配给两个用户。
需要说明的是,上述实施例无论覆盖内还是覆盖外,在确立了所有用户的数据资源后,如eNodeB通过DCI分配了其调度用户的数据资源,或D2D UE分配了其所调度用户的数据资源,D2D Relay UE或D2D UE通过 N个PSCCH信道为每个用户分配资源,其分配的原则是其服务的用户的时域资源正交或频域资源连续,如图9和如图10所示。
综上所述,本发明实施例支持在一个PSCCH周期内为第二UE分配N个频率连续的PSCCH资源、以及在所选择的频域资源采用时域正交或频域连续PSSCH资源,从而使得本发明实施例能够支持D2D UE在一个PSCCH周期内同时服务多个UE,促进了D2D通信的发展改进;通过基站调度设备之间通讯的物理资源,解决了设备间的通讯和原有网络中通讯的干扰问题,实现了用户设备之间的直接通讯,提高了频谱效率。
