Description

通信处理方法、装置及用户设备 技术领域
本发明涉及通信领域,具体而言,涉及一种通信处理方法、装置及用户设备。
背景技术
在蜂窝通信系统中,当两个用户设备(User Equipment,简称为UE)之间有业务传输时,例如,用户设备1(UE1)到用户设备2(UE2)的业务数据,首先通过空口传输给UE1所在小区的基站(Base Station,或者称为Node B,或演进(evolved)Node B),该基站通过核心网将该用户数据传输给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。如图1、2所示,图1是相关技术中的同一基站小区的UE的蜂窝通信示意图,图2是相关技术中的蜂窝网络部署示意图,当UE1和UE2位于同一个蜂窝小区,虽然两个UE由同一个基站的小区覆盖,数据传输时仍然需要通过核心网中转,并且一次数据传输仍然会消耗两份无线频谱资源,图3是相关技术中的无线资源结构的示意图。
由此可见,如果用户设备1和用户设备2相距较近,那么上述的蜂窝通信方法显然不是最优的。而实际上,随着移动通信业务的多样化,例如,社交网络、电子支付等应用在无线通信系统中的普及,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(Device-to-Device,简称为D2D)的通信模式日益受到广泛关注。如图4所示,图4是相关技术中的同一基站小区的UE的D2D通信示意图,D2D是指业务数据不经过基站和核心网的转发,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(Proximity Service,简称为ProSe)。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。
D2D的技术类型包括发现(discovery)和通信(communication),其中discovery包括Type 1和type 2两种类型,communication包括mode 1和mode 2两种类型。在第三代合作伙伴计划(3rd Generation Partnership Project,简称为3GPP)无线接入网工作组1(Radio Access Network Work Group 1,简称为RAN1)讨论的长期演进(Long Term Evolution,简称为LTE)R12(Release 12)阶段,communication的适用场景包括网络覆盖内、网络覆盖外、以及网络半覆盖场景。而对于discovery,只适用于覆盖内场景。
在R13阶段,3GPP技术规范组(Technology Standards Group,简称为TSG)提出在半覆盖和覆盖外场景应用Type 1 discovery的需求。对于半覆盖和覆盖外场景,目前,还没有实现Type 1 discovery的同步和资源配置的方案。而对于communication,目前 虽然支持半覆盖和覆盖外场景,但是对于半覆盖场景,也需要解决覆盖外UE如何获取覆盖内UE的资源池信息,以实现与覆盖内UE的资源池对齐的问题。否则,覆盖外UE发送D2D信号或数据会对网络蜂窝通信和覆盖内D2D通信形成干扰。目前在这个问题上还没有确定的方案。
针对相关技术中存在的无法实现覆盖场景外和半覆盖场景下D2D通信的问题,目前尚未提出有效的解决方案。

通过上述步骤,首先确定进行D2D发现和/或通信处理的资源,这样发送端UE和接收端UE便能够相互统一资源配置参数,以正确进行D2D信号/数据的发送和/或接收,从而解决了相关技术中存在的无法实现覆盖场景外和半覆盖场景下D2D通信的问题,进而达到了实现覆盖场景外和半覆盖场景下D2D通信的效果。
在确定用于与用户设备进行D2D发现和/或通信处理的资源时,可以有多种确定方法,在一个可选的实施例中,可以通过如下方式确定用于与用户设备进行D2D发现和/或通信处理的资源:检测用户设备发送的D2D同步信号和/或D2D同步信道,其中,该D2D同步信号中携带有用于指示上述资源的第一指示参数,该D2D同步信道中携带有用于指示上述资源的第二指示参数,上述第一指示参数的个数为一个或多个,上 述第二指示参数的个数为一个或多个;根据D2D同步信号、D2D同步信道、新增的指示消息中的至少之一确定上述资源,其中,该新增的指示消息中携带有用于指示上述资源的第三指示参数,该第三指示参数的个数为一个或多个。

为使本发明的目的、技术方案和优点更加清楚明白,下面结合具体的实施例对本发明作进一步详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
本发明实施例中的技术适用于蜂窝无线通信系统或网络。常见的蜂窝无线通信系统可以基于码分多址(Code Division Multiplexing Access,简称为CDMA)技术、频分多址(Frequency Division Multiplexing Access,简称为FDMA)技术、正交频分多址(Orthogonal-FDMA,简称为OFDMA)技术、单载波频分多址(Single Carrier-FDMA,简称为SC-FDMA)技术,等。例如,3GPP LTE/高级长期演进(LTE-Advanced,简称为LTE-A)蜂窝通信系统下行链路(或称为前向链路)基于OFDMA技术,上行链路(或称为反向链路)基于SC-FDMA多址技术。未来则有可能在一个链路上支持混合的多址技术。
在OFDMA/SC-FDMA系统中,用于通信的无线资源(Radio Resource)是时-频两维的形式。例如,对于LTE/LTE-A系统来说,上行和下行链路的通信资源在时间方向上都是以无线帧(radio frame)为单位划分,每个无线帧(radio frame)长度为10ms,包含10个长度为1ms的子帧(sub-frame),每个子帧包括长度为0.5ms的两个时隙(slot),如前述的图3所示。而根据循环前缀(Cyclic Prefix,简称为CP)的配置不同,每个时隙可以包括6个或7个OFDM或SC-FDM符号。
在频率方向,资源以子载波(subcarrier)为单位划分,通信中,频域资源分配的 最小单位是资源块(Resource Block,简称为RB),对应物理资源的一个物理资源块(Physical RB,简称为PRB)。一个PRB在频域包含12个子载波(sub-carrier),对应于时域的一个时隙(slot)。每个OFDM/SC-FDM符号上对应一个子载波的资源称为资源单元(Resource Element,简称为RE)。
在LTE/LTE-A蜂窝通信中,用户设备UE通过检测同步信号(Synchronization Signal,简称为SS)发现LTE网络。同步信号包括有主同步信号(Primary SS,简称为PSS)和辅同步信号(Secondary SS,简称为SSS)。通过检测同步信号,UE获得与基站的下行频率和时间同步。并且,由于同步信号携带有物理小区标识,检测同步信号也意味着UE发现LTE/LTE-A小区。
在上行链路,当UE有上行数据传输时,需要发起随机接入(Random Access,简称为RA)进行上行同步并建立无线资源控制(Radio Resource Control,简称为RRC)连接,即从RRC空闲(Idle)状态进入RRC连接(Connected)状态。随机接入时UE需要发送随机接入前导(preamble),网络侧通过在特定的时频资源中检测随机接入前导,实现对UE的识别和上行链路的同步。
前述的图2中所示的可以是3GPP LTE/LTE-A系统,或者其它的蜂窝无线通信技术。在蜂窝无线通信系统的接入网中,网络设备一般包括一定数量的基站(base station,或者称为节点B,简称为Node B,或者演进的节点B,evolved Node B,简称为eNB,或者增强的节点B,enhanced Node B,简称为eNB),以及其它的网络实体(network entity)或网络单元(network element)。或者,概括来说,在3GPP中也可以将其统称为网络侧演进的通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network,简称为E-UTRAN)。这里所说的基站也包括网络中的低功率节点(Low Power Node,简称为LPN),例如毫微微小区或家庭基站(pico,Relay,femto,HeNB即Home eNB等)。为描述简单,图3中只示出了3个基站。基站提供一定的无线信号覆盖范围,在该覆盖范围内的终端(terminal,或者称为用户设备,User Equipment,UE,或者device)可以与该基站进行无线通信。一个基站的无线信号覆盖区域可能会基于某些准则被划分为一个或者多个小区cell或扇区sector,例如可能会是三个小区。
在D2D通信时,也存在类似的发送端UE与接收端UE之间的同步,即发送端UE与接收端UE参照相同的定时参考,完成对D2D信号/数据的发送和接收。同时,接收端UE需要与发送端UE基于相同的D2D资源配置参数,否则不能正确地完成D2D信号/数据的接收。
对于网络覆盖内D2D UE,基站通过RRC参数方式为D2D UE配置资源参数,使得D2D接收端UE与发送端UE的资源配置参数相同,或者接收端UE通过RRC参数获取到发送端UE的资源配置参数。而对于覆盖外D2D UE,虽然保存有预配置的D2D 资源配置参数,但是当覆盖外UE的预配置参数所对应的小区的资源配置参数发生改变时,或者覆盖外UE移动到资源配置参数与该覆盖外UE的预配置参数不同的小区边缘时,如果覆盖外UE与覆盖内UE要进行D2D发现或通信,则发送端UE和接收端UE需要相互统一资源配置参数,以正确进行D2D信号/数据的发送和/或接收。
实施例一
覆盖外UE与覆盖内UE之间要进行D2D发现或通信,首先需要实现D2D定时同步,覆盖外UE通过检测覆盖内UE发送的D2D同步信号(D2DSS)和/或D2D同步信道(PD2DSCH)可以实现与覆盖内UE的定时同步。
同时覆盖外UE和覆盖内UE还需要基于相同的D2D资源配置参数,覆盖内UE对于D2D信号/数据的发送和/或接收是基于基站配置的RRC参数获得D2D资源配置参数,因此覆盖外UE需要获取覆盖内UE的D2D资源配置参数,来实现与覆盖内UE的D2D发现/通信。这里的D2D发现包括Type 1D2D发现。
该实施例中描述的D2D资源配置参数,至少包括描述D2D资源池频域资源和时域资源的参数,比如:对于discovery UE,包括:discovery资源池起始PRB,discovery资源池PRB个数,discovery资源池结束PRB,discovery资源池周期,discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,指示discovery子帧的bitmap,bitmap的重复次数等等,和描述D2D信号或/和数据发送形式的参数,比如:discovery信号在一个资源池周期内重复的次数,discovery信号的CP类型,discovery信号发送的功率控制参数等等。
还比如,对于communication UE,至少包括:调度任务(Scheduling Assignment,简称为SA)和数据的资源池周期,SA的CP类型,SA资源池的PRB个数,SA资源池的起始PRB,SA资源池的结束PRB,第一个SA资源池周期在SFN/DFN周期内相对SFN/DFN#0的偏移,SA对应子帧的位图bitmap,数据资源池的Type 2跳变参数等等。或者,还包括接收资源池的参数,对应各相邻小区的D2D配置参数,比如:discovery接收资源池个数,接收资源池对应的索引,邻区discovery信号的CP类型,接收discovery资源池的PRB个数,接收discovery资源池的起始PRB,接收discovery资源池的结束PRB,邻区discovery信号在一个资源池周期内重复的次数,接收资源池对应的TDD配置格式,接收discovery资源池在SFN/DFN周期内第一个周期相对服务小区SFN/DFN#0的偏移,接收资源池指示discovery子帧的bitmap,bitmap的重复次数等等。
通过D2D同步信道(PD2DSCH)携带指示信息,指示覆盖内UE的D2D资源配 置参数,也可以描述为指示覆盖内UE的D2D资源或资源配置,覆盖外UE可以获取覆盖内UE的D2D资源配置参数。对于D2D发现,相关技术中发现UE不发送PD2DSCH,本实施例中包括D2D发现UE发送PD2DSCH,发送PD2DSCH的周期可以与D2D同步信号(D2DSS)相同,也可以不同。
另外,对于发现UE discovery UE,也可以结合D2DSS和/或PD2DSCH的发送周期或/和偏移来确定discovery资源池的周期或/和偏移。通过检测D2DSS和/或PD2DSCH的发送周期来确定discovery资源池的周期,检测到D2DSS和/或PD2DSCH,通过PD2DSCH中的1bit指示,可以确定D2DSS和/或PD2DSCH所在子帧是否为discovery资源池的第一个子帧。比如:如果1bit指示值为1,则D2DSS和/或PD2DSCH所在子帧为discovery资源池的第一个子帧,可以直接确定discovery子帧bitmap的起始子帧;如果1bit指示值为0,则D2DSS和/或PD2DSCH所在子帧不是discovery资源池的第一个子帧,那么根据discovery UE的D2DSS发送条件,可确定discovery资源池周期的起始位置在一个D2DSS/PD2DSCH周期(40ms)之内,或者,在PD2DSCH中携带6bit进行指示精确的位置。
实施例二
对于D2D同步信道(PD2DSCH)携带指示信息,本实施例列举一种指示完整参数值的指示方法。
这种方式能够比较精确地指示资源配置参数的取值,比如:对于discovery UE,指示信息内容包括:7bit指示discovery资源池起始PRB,7bit指示discovery资源池PRB个数,7bit指示discovery资源池结束PRB;或者,3bit指示discovery资源池周期,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,42bit指示discovery子帧的bitmap,6bit指示bitmap的重复次数;或者,7bit指示discovery资源池起始PRB,7bit指示discovery资源池结束PRB;3bit指示discovery资源池周期,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,42bit指示discovery子帧的bitmap,6bit指示bitmap的重复次数。
或者,通过控制指示信息内容在20bit以内,比如:指示信息内容包括:7bit指示discovery资源池起始PRB,7bit指示discovery资源池结束PRB;或者,3bit指示discovery资源池周期,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移;或者,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移。
以上只是列举出部分的指示参数的组合。
实施例三
对于D2D同步信道(PD2DSCH)携带指示信息,本实施例列举一种指示部分参数值的指示方法。
这种方式可以通过对配置参数的取值进行量化之后,在指示信息中指示资源配置参数的量化值。每个量化值相比量化之前的指示值指示的更粗,对应一个范围。举例来说,假设某个配置参数所有可能取值为64种,不用量化的方式指示需要6bit,每个6bit的指示值精确地指示到64种取值中的一种。若采用量化方式,量化到3bit,则总共只能指示8个值,每个值对应一个取值范围,包括8个精确取值,配置参数的具体取值为8个精确取值中的某一个。
采用量化指示方式指示D2D资源配置参数,对于discovery UE,可以包括不同的参数组合,比如:4bit指示discovery资源池起始PRB,4bit指示discovery资源池PRB个数,4bit指示discovery资源池结束PRB,3bit指示discovery资源池周期;或者,4bit指示discovery资源池起始PRB,4bit指示discovery资源池结束PRB,3bit指示discovery资源池周期,4bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,3bit指示discovery子帧的bitmap;或者,3bit指示discovery资源池周期,4bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,5bit指示discovery子帧的bitmap,5bit指示bitmap的重复次数;或者,3bit指示discovery资源池周期,4bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,12bit指示discovery子帧对应在discovery资源周期内的范围。
以上只是列举了部分的指示参数,以及部分的量化bit长度的组合。
或者,这种方式还可以通过约束部分或全部配置参数的取值,减少配置参数的可能取值,对约束后的参数取值进行指示,使得指示bit的位数减少。比如:对于discovery资源池起始PRB,只取索引为5的倍数的PRB,这样只需要5bit指示discovery资源池起始PRB对应的索引,也可以通过1bit来指示discovery资源池起始PRB的索引为奇数或偶数;或者,对于discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,只取子帧号能被10整除的子帧,这样只需要10bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移值对应的索引;或者,对于discovery子帧的bitmap,只取discovery子帧连续分布的情况,这样只需要6bit指示discovery子帧的bitmap对应的索引。
以上只是列举了部分的限制参数取值,通过指示限制后参数取值对应索引的例子。
实施例四
对于D2D同步信道(PD2DSCH)携带指示信息,本实施例列举一种指示参数值的组合对应的索引的指示方法。
这种方式可以通过对各个配置参数的不同取值进行组合,在指示信息中指示组合所对应的索引。比如:对于discovery UE,指示信息内容为索引0时对应的参数值为:discovery资源池起始PRB为PRB#0,discovery资源池PRB个数为1,discovery资源池结束PRB为PRB#1;或者,指示信息内容为索引1时对应的参数值为:discovery资源池周期为640ms,discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移为1,discovery子帧的bitmap为只有第一个bit是1其余bit都是0,bitmap的重复次数为1。
这种方式也可以通过对配置参数取值进行量化之后的不同取值进行组合,在指示信息中指示组合所对应的索引。比如:通过用4bit量化discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,指示信息内容为索引0时表示对应参数值组合中discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移为0~640ms;或者,对于TDD下的discovery子帧bitmap,量化为8bit,则每bit代表对应原始的40bit中的5bit段中是否有bit位取值为1,如果指示索引为1则表示在对应参数值组合中discovery子帧bitmap的40bit中最后5bit中有bit位的取值为1。
这种方式还可以通过对配置参数取值进行限制之后的不同取值进行组合,在指示信息中指示组合所对应的索引。比如:限制discovery资源池起始PRB取值为0,5,10,20,discovery资源池PRB个数为5,10,20,40,则指示信息内容为索引0时表示discovery资源池起始PRB为0,discovery资源池PRB个数为5;而指示信息内容为索引3时表示discovery资源池起始PRB为20,discovery资源池PRB个数为40。
以上只是列举了部分的指示参数,以及部分的组合例子。
实施例五
对于新增指示消息携带指示信息,本实施例列举一种通过新定义指示消息来指示参数的方法。
这种指示方式可以指示资源配置参数完整取值,指示的内容包括不同配置参数的 组合。比如:对于discovery UE,包括:7bit指示discovery资源池起始PRB,7bit指示discovery资源池PRB个数,7bit指示discovery资源池结束PRB;或者,3bit指示discovery资源池周期,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,42bit指示discovery子帧的bitmap,6bit指示bitmap的重复次数;或者,7bit指示discovery资源池起始PRB,7bit指示discovery资源池结束PRB;3bit指示discovery资源池周期,14bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,42bit指示discovery子帧的bitmap,6bit指示bitmap的重复次数。
或者,类似实施例三,也可以通过量化的方法只指示配置参数的部分取值,比如:4bit指示discovery资源池起始PRB,4bit指示discovery资源池PRB个数,4bit指示discovery资源池结束PRB,3bit指示discovery资源池周期;或者,4bit指示discovery资源池起始PRB,4bit指示discovery资源池结束PRB,3bit指示discovery资源池周期,4bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,3bit指示discovery子帧的bitmap。
或者,类似实施例三,还可以通过约束配置参数取值的方法,指示配置参数的部分取值。比如:对于discovery资源池起始PRB,只取索引为5的倍数的PRB,这样只需要5bit指示discovery资源池起始PRB对应的索引,也可以通过1bit来指示discovery资源池起始PRB的索引为奇数或偶数;或者,对于discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移,只取子帧号能被10整除的子帧,这样只需要10bit指示discovery资源池在SFN/DFN周期内第一个周期相对SFN/DFN#0的偏移值对应的索引;或者,对于discovery子帧的bitmap,只取discovery子帧连续分布的情况,这样只需要6bit指示discovery子帧的bitmap对应的索引。
以上只是列举了部分的指示参数取值的例子。
这种新增指示信息可以通过新定义物理信道来承载,比如按照物理广播信道(Physical Broadcast Channel,简称为PBCH)的方式来定义。也可以在PD2DSCH承载,占用时域资源为D2D同步信号子帧,频域资源为分配给D2D同步信号资源的中间6个(当然,也可以为其他数量)PRB之外的频域部分,同时,不包括分配给物理上行链路控制信道(Physical Uplink Control CHannel,简称为PUCCH)的频域资源;在时域上,可以占用整个D2D同步信号子帧但不包括最后一个SC-FDMA符号,或者占用没有发送D2D同步信号和/或D2D同步信道的SC-FDMA符号,但不包括最后一个SC-FDMA符号。或者,频域上占用中间6个(或其他数量)PRB,时域上为没有映射D2D同步信号和上行参考信号DMRS的SC-FDMA符号,同时,不包括子帧内最后一个SC-FDMA符号。如图9中的(a),(b)所示,图9是根据本发明实施例的 指示消息占用资源的示意图,其中图9中的(b)对应为常规CP的情况。900和901为新增指示信息占用的无线资源,D2D UE可以占用900或/和901对应的无线资源发送新增指示消息。或者,对于discovery UE,只占用901对应的无线资源发送新增指示消息。对于communication UE,在D2D同步信号子帧已经发送了PD2DSCH,那么新增指示信息可以频域上占用中间6个PRB,时域上为D2D子帧中没有映射D2D同步信号和上行参考信号DMRS,以及PD2DSCH的SC-FDMA符号,同时,不包括子帧内最后一个SC-FDMA符号。
在时域上,新增指示消息在D2D同步信号资源周期地发送,发送周期可以采用固定周期,比如160ms,320ms,640ms等。图10是根据本发明实施例的周期发送指示消息的示意图,图10为周期为320ms的一个例子,每320ms发送一次discovery资源配置信息的指示消息。对应发送指示消息的D2D同步信号资源的offset可以采用固定的offset,或者,基于D2DSS资源的offset确定,比如offset 2=offset 1+M*40,粒度为ms,其中offset 1为D2DSS资源对应offset,M为偏移的D2DSS资源个数。接收UE同步后,根据PD2DSCH携带的SFN/DFN信息计算出offset 1,然后根据上述公式计算出offset 2。
或者,新增指示消息在D2D同步信号资源采用非周期发送,通过在PD2DSCH中携带内容来指示新增指示消息的发送。通过1bit的指示位来指示是否有配置信息发送。如果覆盖外UE解得PD2DSCH中的指示位为1,则确定在40ms(或80cm,160cm等)之后的D2DSS资源有配置信息的指示消息发送。如果为0,则不需考虑对配置信息的接收。图11是根据本发明实施例的非周期发送指示消息的示意图,图11所示为周期为640ms的一个例子,在对应发送了D2DSS/PD2DSCH的D2DSS资源,只有PD2DSCH中指示为1时,对应40ms之后的D2DSS资源才发送discovery资源配置信息的指示消息。
或者,对于discovery UE,新增指示消息还可以基于D2DSS的偏移进行发送,UE在连续两次发送D2DSS的D2DSS资源之间,选择一个D2DSS资源发送新增指示消息。比如,UE发送D2DSS后,选择在40ms后的下一个D2DSS资源发送新增指示消息,接收UE在检测到D2DSS后,在40ms偏移后接收资源配置参数的指示消息。
在发送新增指示消息的D2DSS资源,不再发送D2DSS和/或PD2DSCH。另外,对于discovery UE和communication UE,发送新增指示消息可以采用不同周期,或者,采用相同周期,而周期对应的的offset可以相同或不同。

Discovery UE与communication UE可以采用不同的周期和/或不同的对应周期的偏移来发送D2DSS和/或PD2DSCH,来相互进行区分,避免同周期发送情况下接收资源配置参数在discovery UE和communication UE之间形成干扰。接收UE在完成D2D同步后,可以确定同步源UE为discovery UE或communication UE,并根据获取到的资源配置参数,确定对应的发送或/和接收资源池,并发送或/和接收对应的discovery信号或/和SA/data。
还可以在PD2DSCH中增加对discovery UE和communication UE的指示,比如:在PD2DSCH携带内容中增加2bit,指示10表示发送D2DSS/PD2DSCH的UE为discovery UE,指示01表示发送D2DSS/PD2DSCH的UE为communication UE。或者,在PD2DSCH携带内容中增加1bit,指示0表示发送D2DSS/PD2DSCH的UE为discovery UE,指示1表示发送D2DSS/PD2DSCH的UE为communication UE。
Discovery UE和communication UE可以根据PD2DSCH中的指示,选择是否同步到对应D2DSS/PD2DSCH的同步源UE上。例如,如图12所示,图12是根据本发明实施例的覆盖外UE根据指示选择同步源的示意图,假设UE1200、UE1202为discovery UE,UE1201为communication UE。UE1201和UE1202为独立同步源,UE1200能检测到UE1201和UE1202发送的D2DSS,并且收到UE1201的D2DSS的接收功率更大。但是,UE1200通过PD2DSCH中的指示,可以识别UE1201为communication UE,UE1202为discovery UE。由于UE1200为discovery UE,优先选择同步到discovery的同步源UE,因此,UE1200选择同步到UE1202上。避免了同步到UE1201后,因为UE1201与UE1202的定时参考不对齐,而不能接收UE1202发送的discovery信号的问题。
实施例七
同一网络覆盖下,隶属不同小区的UE都采用相同的预配置参数来进行预配置,在覆盖外场景下,UE根据同一套的预配置参数进行D2D信号/数据的发送和/或接收。比如,所有discovery UE采用同一套预配置参数,这样相邻的UE实现D2D同步后,在同步区域内所有UE实现DFN同步对齐,同时,同步区域内所有discovery UE基于相同的预配置参数,确定资源池的位置,和/或discovery信号的发送方式,实现同步区域内UE的discovery信号的发送和接收。
对communication UE也同样,假设所有communication UE采用同一套预配置参数,这样相邻的UE实现D2D同步后,在同步区域内所有UE实现DFN同步对齐,同时,同步区域内所有communication UE基于相同的预配置参数,确定资源池,和/ 或SA/data的发送方式,实现同步区域内UE的SA/data的发送和接收。
如果UE能够接收到对于D2D资源配置参数的指示消息,则UE根据指示消息的内容确定D2D资源池,来实现D2D信号或数据的接收和/或发送。
显然,本领域的技术人员应该明白,上述的本发明的各模块或各步骤可以用通用的计算装置来实现,它们可以集中在单个的计算装置上,或者分布在多个计算装置所组成的网络上,可选地,它们可以用计算装置可执行的程序代码来实现,从而,可以将它们存储在存储装置中由计算装置来执行,并且在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤,或者将它们分别制作成各个集成电路模块,或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样,本发明不限制于任何特定的硬件和软件结合。
