Description

通信数据发送方法、装置及用户设备 技术领域
本发明涉及通信领域,具体而言,涉及一种通信数据发送方法、装置及用户设备。
背景技术
在设备到设备(Device to Device,简称为D2D)通信系统中,用户设备(User Equipment,简称为UE)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,图1是根据相关技术的D2D通信结构的示意图,如图1所示,这种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(evolved NodeB,简称为eNB)统一控制调度,eNB通过物理下行控制信道(Physical Downlink Control Channel,简称为PDCCH)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。
在长期演进(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。当系统帧结构采用普通循环前缀(Normal Cyclic Prefix,简称为Normal CP)时,每个子帧含有14个单载波频分多址(Single-carrier Frequency Division Multiple Access,简称为SC-FDMA)符号或正交频分复用(Orthogonal Frequency Division Multiplexing,简称为OFDM)符号,分为2个slot,每个slot上包括7个符号。当系统帧结构采用扩展循环前缀(Extended Cyclic Prefix,简称为Extended CP)时,每个子帧含有12个符号,每个slot上包括6个符号。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的划分单位,eNB为UE调度时频资源的最小单位为资源块(Resource Block,简称为RB),RB定义为在时域上为1个slot,在频域上为连续的
Figure PCTCN2014086969-appb-000001
个子载波,
Figure PCTCN2014086969-appb-000002
如图3所示,eNB对UE的资源配置指示具体有两种 方式,称为资源配置指示方式0和资源配置指示方式1,基于这两种资源配置指示方式eNB可以灵活地为UE调度指示一个或多个RB资源。
在蜂窝通信中,eNB在下行子帧#n的PDCCH资源上向UE调度指示在当前子帧所配置的物理下行共享信道(Physical Downlink Shared Channel,简称为PDSCH)资源,UE接收PDCCH中的指示信息,并根据指示信息接收在子帧#n中的相应RB上的信号,获得eNB传输的数据,如图4所示。因此,在D2D通信中,发射端UE向接收端UE指示所使用的D2D数据信道资源时,无法使用蜂窝通信中的eNB向UE调度指示资源的方法。
针对相关技术中D2D通信的发射端UE无法指示所使用的D2D数据信道资源的问题,目前尚未提出有效的解决方案。

在D2D通信系统中,UE之间直接进行数据的传输,发射端UE需要发送D2D控制信息,向接收端UE指示所传输的数据信号所使用的资源等相关信息,由于D2D通信的特殊性,发射端UE在D2D控制信息中需要指示一个或多个D2D数据子帧(D2D  data subframe,即用于发送D2D通信数据的数据子帧)的相关控制信息,尤其是指示所使用的D2D数据信道(D2D data channel)资源。
为了实现上述目的,本发明提供了下列实施例:
本实施例提供了一种通信数据发送方法,图5是根据本发明实施例的通信数据发送方法的流程示意图,如图5所示,该流程包括如下步骤:
步骤S502,UE通过D2D控制指示信息中的D2D数据信道资源指示信息和/或D2D控制指示信息对应的索引信息指示D2D数据信道资源;
步骤S504,UE在D2D数据信道资源上发送D2D通信数据。
其中,上述步骤S502包括以下至少之一:
1、UE通过D2D数据信道资源指示信息指示D2D数据信道的时域资源和频域资源;
2、UE通过D2D数据信道资源指示信息指示D2D数据信道的时域资源,并通过索引信息指示D2D数据信道的频域资源;
3、UE通过D2D数据信道资源指示信息指示D2D数据信道的频域资源,并通过索引信息指示D2D数据信道的时域资源;
4、UE通过索引信息指示D2D数据信道的时域资源和频域资源。
通过上述步骤,采用D2D控制指示信息中的D2D数据信道资源指示信息和/或D2D控制指示信息对应的索引信息指示D2D数据信道资源,解决了D2D通信的发射端UE无法指示所使用的D2D数据信道资源的问题,实现了D2D UE之间的D2D数据信道资源的指示及D2D数据的传输。

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。下面将进一步参考附图并结合实施例来详细说明本发明。
在D2D通信系统中,有D2D数据待发送的D2D发射端UE可以从eNB获得D2D通信的数据信道资源配置,或者在系统预定义的资源池中选择一定的数据信道资源使用,不论发射端UE如何获得D2D数据信道资源,发射端UE都需要通过D2D控制指 示信息向接收端UE指示所使用的D2D数据信道资源,以及其他与D2D数据发射相关的控制信息,如调制和编码方案(MCS)、用户设备标识(UE ID)等,因此D2D控制指示信息也可以称为调度配置(Scheduling Assignment,简称为SA)信息。
D2D通信的资源可以包括以下的一种或多种:D2D数据信道(Data channel)、D2D控制信道(Control channel)、D2D发现信道(Discovery channel)、D2D SA资源、D2D同步信道、D2D共享信道等。其中,发射端UE可以在D2D Control channel、或D2D Data channel、或D2D SA资源(resource)上发送D2D控制指示信息,下面以D2D控制指示信息承载在SA resource上为例进行说明,其他情况可类似获得。
设SA resource共享D2D Data channel资源,以子帧(subframe)为单位划分为SA subframe和Data subframe,在SA subframe上承载D2D控制指示信息,在Data subframe上承载D2D数据。每个SA subframe上可承载多个发射端UE的D2D控制指示信息,每个UE的D2D控制指示信息可以指示之后的一个或多个Data subframe上的D2D data channel资源配置及相关信息。这里,将两次有效的D2D控制指示信息传输(不包含重传)之间的时间定义为D2D控制指示周期(即D2D调度配置周期,D2D scheduling assignment period),则D2D控制指示信息可以指示在一个D2D控制指示周期内的所有D2D data subframe上的D2D data channel资源,如图8所示。需要注意的是,图8中所示SA subframe与D2D data subframe相邻且连续的关系是逻辑关系,在实际系统中,SA subframe与D2D data subframe在时间上可以是离散的,其中可以存在其他非D2D communication相关的子帧,本发明中的所有实例及附图都以此为基础进行说明,不再赘述。
发射端UE通过D2D控制指示信息向一个或多个接收端UE指示出相应的D2D数据信道资源配置,使接收端UE在收到D2D控制指示信息后,能够获得D2D数据信道资源指示,并根据指示在相应的D2D数据信道资源上接收所需的数据。
基于D2D控制指示信息中的D2D数据信道资源指示信息和/或D2D控制指示信息对应的索引信息,发射端UE可以灵活的指示相应的D2D数据信道资源,包括时域资源和频域资源,具体的,有以下4种方法。

D2D数据信道资源指示信息是包含在D2D控制指示信息中的N bit指示信息,用于指示对应的D2D数据信道的时域和频域资源。进一步的,通过N bit指示信息指示D2D数据信道的时域和频域资源时,分为两种方式:
方式一,N bit指示信息分为两部分,N1 bit用于指示对应的D2D数据信道的时域资源,N2 bit用于指示对应的D2D数据信道的频域资源,N1+N2=N。
以N1 bit指示D2D数据信道的时域资源,有两种指示方法:位图(bitmap)指示,以及时域图样(timing pattern)指示。
以N1 bit对时域资源进行bitmap指示时,即以N1 bit对应于N1个D2D data subframe,每bit位的指示信息即表示相应的D2D data subframe是否为此发射端UE的D2D数据信道的时域资源。
以N1 bit对时域资源进行timing pattern指示时,预定义N1 bit的各指示值与相应的timing pattern之间的对应关系,使N1 bit指示信息能够唯一对应于一个timing pattern,每个timing pattern表示固定的一个或多个D2D data subframe。
以N2 bit指示D2D数据信道的频域资源,有两种指示方法:以LTE系统对上行资源的资源配置指示方式1和资源配置指示方式0(resource allocation type 1 and type 0)指示对应的D2D数据信道的频域资源,以及指示频域图样frequency pattern的方法。
其中,以N2 bit指示frequency pattern时,预定义N2 bit的各指值与相应的frequency pattern之间的对应关系,使N2 bit指示信息能够唯一对应于一个frequency pattern,每个frequency pattern表示固定的一个或多个RB。
进一步的,N2 bit指示信息中还可以指示对应的D2D数据信道频域资源是否进行频域跳频(frequency hopping),以及指示使用的跳频方式。
方式二,N bit指示信息综合指示对应的D2D数据信道的时域和频域资源,即以N bit指示D2D数据信道资源图样resource pattern,预定义N bit的各指示值与相应的resource pattern之间的对应关系,使N bit指示信息能够唯一对应于一个resource pattern,每个resource pattern表示固定的一个或多个D2D data subframe以及相应的每个D2D data subframe上固定的一个或多个RB。
方法二
通过D2D控制指示信息中的D2D数据信道资源指示信息指示相应的D2D数据信道的时域资源,并以D2D控制指示信息对应的索引信息隐含指示D2D数据信道的频域资源。
D2D数据信道资源指示信息是包含在D2D控制指示信息中的N bit指示信息,用于指示对应的D2D数据信道的时域资源。进一步的,通过N bit指示信息指示D2D数据信道的时域资源时,有两种指示方法:位图(bitmap)指示,以及时域图样(timing pattern)指示。
以N bit对时域资源进行bitmap指示时,即以N bit对应于N个D2D data subframe,每bit位的指示信息即表示相应的D2D data subframe是否为此发射端UE的D2D数据信道的时域资源。
以N bit对时域资源进行timing pattern指示时,预定义N bit的各指示值与相应的timing pattern之间的对应关系,使N bit指示信息能够唯一对应于一个timing pattern,每个timing pattern表示固定的一个或多个D2D data subframe。
D2D控制指示信息对应的索引信息与承载D2D控制指示信息的资源相关,D2D控制指示信息可以承载在D2D Control channel、或D2D Data channel、或D2D SA resource上,索引信息是指承载相应D2D控制指示信息的信道或资源的信道索引号、或资源索引号,或频域RB索引号。因此索引信息是由承载D2D控制指示信息的资源确定,通过索引信息指示D2D数据信道的时域和/或频域资源时,不需要明确的指示信息开销,可以直接根据预定义的规则,通过索引信息按照相应规则确定对时域和/或频域资源的指示。
以D2D控制指示信息对应的索引信息隐含指示D2D数据信道的频域资源时,预定义索引信息与相应的frequency pattern之间的对应关系,使每一个索引信息值能够唯一对应于一个frequency pattern,每个frequency pattern表示固定的一个或多个RB。
方法三
通过D2D控制指示信息中的D2D数据信道资源指示信息指示相应的D2D数据信道的频域资源,并以D2D控制指示信息对应的索引信息隐含指示D2D数据信道的时域资源。
D2D数据信道资源指示信息是包含在D2D控制指示信息中的N bit指示信息,用于指示对应的D2D数据信道的频域资源,以N bit指示D2D数据信道的频域资源,有 两种指示方法:以LTE系统对上行资源的资源配置指示方式1和方式0(resource allocation type 1 and type 0)指示对应的D2D数据信道的频域资源,以及指示频域图样(frequency pattern)的方法。
以N bit指示frequency pattern时,预定义N bit的各指示值与相应的frequency pattern之间的对应关系,使N bit指示信息能够唯一对应于一个frequency pattern,每个frequency pattern表示固定的一个或多个RB。
进一步的,N bit指示信息中还可以指示对应的D2D数据信道频域资源是否进行频域跳频frequency hopping,以及指示使用的跳频方式。
以D2D控制指示信息对应的索引信息隐含指示D2D数据信道的时域资源时,预定义索引信息与相应的timing pattern之间的对应关系,使每一个索引信息值能够唯一对应于一个timing pattern,每个timing pattern表示固定的一个或多个D2D data subframe。
方法四
通过D2D控制指示信息对应的索引信息隐含指示D2D数据信道的时域和频域资源。
以D2D控制指示信息对应的索引信息隐含指示D2D数据信道的时域和频域资源时,预定义索引信息与相应的resource pattern之间的对应关系,使每一个索引信息值能够唯一对应于一个resource pattern,每个resource pattern表示固定的一个或多个D2D data subframe以及相应的每个D2D data subframe上固定的一个或多个RB。
下面基于上述四种方法分别进行说明。
实例一
如方法一、方法二中所述,当以N bit或N1 bit对时域资源进行bitmap指示时,以N/N1 bit对应于N/N1个D2D data subframe,每bit位的指示信息即表示相应的D2D data subframe是否为此发射端UE的D2D数据信道的时域资源。bit位指示为“1”时,表示对应的D2D data subframe为D2D数据信道的时域资源,bit位指示为“0”时,表示对应的D2D data subframe不是D2D数据信道的时域资源;或者,bit位指示为“0”时,表示对应的D2D data subframe为D2D数据信道的时域资源,bit位指示为“1”时,表示对应的D2D data subframe不是D2D数据信道的时域资源。
以bit位指示为“1”/“0”表示对应的D2D data subframe是/否为相应的D2D数据信道的时域资源为例,设N=8,则N bit指示信息为“11110000”时,即指示为在下一个D2D控制指示周期内的8个D2D data subframe中,前4个子帧为此发射端UE的D2D数据信道时域资源,后4个子帧不是发射端UE的D2D数据信道时域资源。
以N bit或N1 bit的D2D数据信道资源指示信息以timing pattern的方式指示D2D数据信道的时域资源时,需预定义N/N1 bit与timing pattern之间的对应关系。
N/N1 bit指示的timing pattern所包含的D2D data subframes数量取决于D2D控制指示周期,即在两次有效的控制指示信息发射间隔以内的所有D2D data subframes。
以N/N1=3,D2D控制指示周期内含有8个D2D data subframes为例,可以预定义N/N1 bit指示信息的各指示值与对应的D2D data subframe timing pattern如表1所示。基于此预定义关系,UE可根据D2D数据信道资源指示信息中的指示,确定相应的D2D数据信道的时域资源配置,如图9所示,当UE 1的D2D控制指示信息中的D2D数据信道资源指示信息为“001”时,即表示采用时域图样索引(timing pattern index)#1,即使用控制指示周期内的前4个子帧,UE 2的控制指示信息中的D2D数据信道资源指示信息为“101”时,即表示采用timing pattern index#5,即使用控制指示周期内的第5、6个子帧。

实例二
如方法一、方法二中所述,当以N bit或N2 bit以frequency pattern的方式指示D2D数据信道的频域资源时,需预定义N/N2 bit与frequency pattern之间的对应关系。
N/N2 bit指示的frequency pattern所包含的频域RB范围取决于D2D data channel可用的频域带宽,即在D2D data channel可用的带宽上所有的RBs。
以N/N2=4,D2D data channel可用带宽内共M个RB为例,可以预定义N/N2 bit指示信息的各指示值与对应的frequency pattern如表2所示。基于此预定义关系,UE可根据D2D数据信道资源指示信息中的指示,确定相应的D2D数据信道的频域资源配置,如图10所示,当UE 1的D2D控制指示信息中的D2D数据信道资源指示信息为“0010”时,即表示采用频域图样索引(frequency pattern index)#2,即配置使用的RB index包括
Figure PCTCN2014086969-appb-000004
UE 2的控制指示信息中的D2D数据信道资源指示信息为“1011”时,即表示采用frequency pattern index#11,即配置使用的RB index包括

实例三
如方法一所述,发射端UE通过D2D控制指示信息中的D2D数据信道资源指示信息指示用于承载D2D数据的D2D数据信道的时域和频域资源,其中,以N1 bit基于bitmap方式指示时域资源配置,以N2 bit指示Frequency pattern进而指示频域资源配置。
以N1=8,N2=4及表2为例说明,UE 1的数据信道资源指示信息为“11000000”+“0110”,其中,“11000000”为时域资源指示信息,指示UE 1的数据信道资源为D2D控制指示周期内的前2个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000008
的频域资源;类似的,UE 2的D2D数据信道资源指示信息为“00110011”+“1100”,指示UE 2的数据信道资源为D2D控制指示周期内的第3、4个和第7,8个D2D data subframe,且在这4个子帧上使用RB index为
Figure PCTCN2014086969-appb-000009
的频域资源,如图11所示。
可以看到,通过N1+N2 bit的D2D数据信道资源指示信息,发射端UE可以达到非常灵活的D2D数据信道资源指示的效果。
实例四
如方法一所述,发射端UE通过D2D控制指示信息中的D2D数据信道资源指示信息指示用于承载D2D数据的D2D数据信道的时域和频域资源,其中,以N bit指示Resource pattern。
以N=4为例,预定义D2D数据信道资源指示信息的各指示值与resource pattern之间的一一对应关系,举例如表3所示。
表3

Figure PCTCN2014086969-appb-000011
基于表3所示的N bit指示信息与resource pattern之间的指示关系,UE 1的D2D数据信道资源指示信息为“1101”,即使用资源图样索引(resource pattern index)#13,指示UE 1的数据信道资源为控制指示周期内的前4个D2D data subframe,且在这4个子帧上使用RB index为
Figure PCTCN2014086969-appb-000012
的频域资源;UE 2的D2D数据信道资源指示信息为“0011”,即使用resource pattern index#3,指示UE 2的数据信道资源为控制指示周期内的最后2个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000013
的频域资源,如图12所示。
可以看到,通过N bit的D2D数据信道资源指示信息与预定义的frequency pattern,发射端UE可以达到非常灵活的D2D数据信道资源指示的效果。
实例五
如方法二所述,发射端UE通过D2D控制指示信息中的D2D数据信道资源指示信息以N bit指示信息指示timing pattern的方式指示相应的D2D数据信道的时域资源,并以承载D2D控制指示信息的control channel index(或者SA resource index)作为索引信息隐含指示D2D数据信道的频域资源。
其中,D2D控制指示信息承载在control channel(或者SA resource)上,所有D2D control channel index(或者SA resource index)都唯一对应于固定的一个或多个RB,举例如表4所示。
表4
Figure PCTCN2014086969-appb-000014
Figure PCTCN2014086969-appb-000015
以N=3及表1、表4为例说明,UE 1的D2D数据信道资源指示信息为“101”,且在D2D控制信道索引(control channel index)#7上承载控制指示信息,则UE 1的数据信道资源为控制指示周期内的第5,6个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000016
的频域资源;类似的,UE 2的D2D数据信道资源指示信息为“011”,且在control channel index#6上承载控制指示信息,则UE 2的数据信道资源为控制指示周期内的前2个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000017
的频域资源;UE 3的D2D数据信道资源指示信息为“101”,且在control channel index#50上承载控制指示信息,则UE 3的数据信道资源为控制指示周期内的第5,6个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000018
的频域资源,如图13所示。
可以看到,通过N bit的D2D数据信道资源指示信息及索引信息的隐式指示,发射端UE可以以非常少的控制指示信息开销达到较灵活的D2D数据信道资源指示的效果。
实例六
如方法三所述,发射端UE通过D2D控制指示信息中的D2D数据信道资源指示信息以N bit指示信息指示frequency pattern的方式指示相应的D2D数据信道的频域资源,并以承载D2D控制指示信息的SA resource的资源块索引(RB index)作为索引信息隐含指示D2D数据信道的时域资源。
其中,D2D控制指示信息承载在SA subframe上,按照所使用的RB资源相应的RB index唯一对应于固定的一个或多个D2D data subframe,举例如表5所示。
表5
SA resource RB index D2D data subframe
0,43 1111 1111
1,2,41,42 1111 0000
3,4,[37,40] 0000 1111
[5,8],[33,36] 1100 0000
[9,12],[29,32] 0011 0000
[13,16],[25,28] 0000 1100
[17,24] 0000 0011
以N=4及表2、表5为例说明,UE 1的D2D数据信道资源指示信息为“1010”,且控制指示信息承载在SA subframe的RB index#5上,则UE 1的数据信道资源为控制指示周期内的前2个D2D data subframe,且在这2个子帧上使用RB index为
Figure PCTCN2014086969-appb-000019
的频域资源;类似的,UE 2的D2D数据信道资源指示信息为“0101”,且控制指示信息承载在SA subframe的RB index#41上,则UE 2的数据信道资源为控制指示周期内的前4个D2D data subframe,且在这4个子帧上使用RB index为
Figure PCTCN2014086969-appb-000020
的频域资源,如图14所示。
可以看到,通过N bit的D2D数据信道资源指示信息及索引信息的隐式指示,发射端UE可以以非常少的控制指示信息开销达到较灵活的D2D数据信道资源指示的效果。
实例七
如方法四所述,发射端UE通过承载D2D控制指示信息的SA resource index作为索引信息隐含指示D2D数据信道的时域和频域资源。
预定义的SA resource index与D2D data channel resource之间的对应关系,举例如图15所示,每个SA resource index对应于固定的时域和频域资源,且每个SA resource index相应的D2D data channel resource所含的D2D data subframe数量及每个子帧上的RB数量相同。
预定义的SA resource index与D2D data channel resource之间的对应关系,举例如图16所示,每个SA resource index对应于固定的时域和频域资源,且每个SA resource index相应的D2D data channel resource所含的D2D data subframe数量相同,但相应的RB数量可以不同。
预定义的SA resource index与D2D data channel resource之间的对应关系,举例如图17所示,每个SA resource index对应于固定的时域和频域资源,且每个SA resource index相应的D2D data channel resource所含的D2D data subframe数量及每个子帧上的RB数量可以根据需求预定义为不同的数量。
可以看到,通过D2D控制指示信息相应的索引信息隐含指示D2D数据信道的时域和频域资源,发射端UE可以不需要任何指示信令开销即可以隐式指示所使用的D2D data channel resource,最大程度的降低了D2D通信的控制指示开销。
