Description

一种信息传输方法、设备及系统 技术领域
本发明涉及通信领域,尤其涉及一种信息传输方法、设备及系统。
背景技术
用户设备之间的临近服务(英文全称:Device to Device Proximity Service,简称:D2D ProSe),已经成为3GPP(英文全称:3rd Generation Partnership Project,中文:第三代合作伙伴计划)LTE(英文全称:Long Term Evolution,中文:长期演进)系统Rel.12(英文全称:Release 12,中文:发布版本12)系统的研究课题。使用LTE系统的物理层(基于OFDM-MIMO,英文全称:Orthogonal Frequency Division Multiplexing-Multiple-Input Multiple-Output,中文:正交频分复用-多输入多输出技术),提供用户设备直连的服务既丰富了LTE系统的业务范围,也使得用户设备之间的D2D通信可以被更多的用户所使用。
在LTE D2D ProSe业务中,一个应用场景是通过UE到UE中继的方法,使用一个UE将另外一个UE的数据中转出去,从而使得传输距离增大。
在LTE的D2D系统中,UE发送D2D信号时,需要在SA(英文全称:scheduiing assignment,中文:调度指配)资源中发送调度信令,然后在数据资源池中,发送相应的D2D信号。D2D终端在SA资源中发送调度信令时,调度信令中包含所发送信号的目的地址。
参照图1,示出一种LTE的D2D系统,该系统中示出了LTE基站和四个UE,如果UE1要发送D2D信号,需要在对应的SA资源中发送调度信令,并在SA资源匹配的数据资源池中发送相应的数据信号。UE1在SA资源中发送的调度信令中包含目的地址,假 设UE1需要和UE3通信,那么此时目的地址就是UE3的地址。
如果UE2用作中继UE1发送的数据,UE2首先是需要先接收再发送,UE2中继UE1的信号存在时延;另外,UE2中继UE1发送的数据时,也需要先在SA资源中发送调度信令,然后在SA资源匹配的数据资源池中发送需要中继的信号。
由于UE2中继UE1的数据时,也需要在SA资源中发送调度信令,并且调度信令中的目的地址也是UE3的地址,若此时UE1需要发送另一数据,则UE1需要在SA资源中发送另一调度信令,并且该另一调度信令的目的地址也是UE3。此时对于图1中的UEx,若UEx参与另一数据的中继发送,UEx在SA资源中接收到两个调度信令的目的地址都是UE3,UEx已经不能区分UE1两次发送的数据的时序关系,从而出现了混淆和模糊,导致D2D通信不能正常进行。

术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量,由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。以下实施例中“第一”和“第二”仅用于区别,如第一信息和第二信息等。
本发明的实施例提供一种通信系统,用于设备间的D2D通信,该系统包括至少3个UE,参照图1所示,还示出了基站eNB。
结合上述的通信系统,提供一种信息传输方法,用于设备间的D2D通信,其中该方法用于传输设备对数据的接收,其中以UE1有数据向UE3发送,则除UE1之外,图1所示的通信系统中示出的其他UE均适用以下方法,参照图2所示该方法包括:

具体的,参照图7所示,提供一种数据结构,包括D2D数据和D2D数据的CRC;本发明的实施例中在CRC中还包括一个CRC的掩码(mask)。
如表1所示,提供一种CRC的掩码的掩码序列和传输层级的对应关系:

4 110011001100110011001100
5 001100110011001100110011
6 111100001111000011110000
7 000011110000111100001111
表1
如表2所示,提供一种CRC的掩码的掩码序列和优先级的对应关系:
优先级 掩码序列
0 000000000000000000000000
1 111111111111111111111111

表3
其中,以上表1-3中各掩码序列之间间隔为预设的汉明距离,其中上表1中传输层级0和传输层级1之间掩码序列的汉明距离为24;其他各传输层级之间最小汉明距离为12;上表2中优先级0和优先级1之间掩码序列的汉明距离为24;其他各优先级之间最小汉明距离为12,上表3中两个来源之间掩码序列的汉明距离为24;当然这只是一种示例,本发明的方案不限于上述方式。
进一步的,第一信息包括至少两个编码段时,步骤502具体为传输设备根据至少两个编码段的CRC获取至少两个CRC的掩码,其中每个编码段对应一个CRC,其中所述至少两个CRC的掩码用于指示第一信息对应信息的信息属性。
以第一信息为D2D数据进行说明,通常,由于D2D UE在发送数据的时候,在物理层中,需要对数据增加循环冗余校验位CRC。当D2D数据的比特数和CRC的比特数的总数大于比特门限的时候(示例性的,LTE系统中是6144比特),D2D数据要分段,此时D2D数据包括至少两个编码段;每个编码段都包括对应的CRC,此时信息属性由至少两个编码段中的CRC对应的CRC的掩码组成。
如图8所示,每个D2D数据包括若干编码段(英文:code segment),每个编码段进行单独的CRC校验,因此每个编码段对应一个CRC。其中具体的,如图8所示,提供一种数据结构,包括D2D数据和D2D数据的CRC;所述D2D数据包括至少两个D2D数据的编码段;信息属性由至少两个编码段中的CRC对应的CRC的掩码组成,两个CRC的掩码之间间隔为预设的汉明距离;此时,通过所有编码段对应的CRC的掩码的掩码序列的组合来指示信息属性。
示例性的,如图8所示,包括两个编码段,每个编码段有各自的CRC。每个编码段的CRC上增加CRC的掩码,假设CRC的掩码有N种掩码序列,则两个编码段的CRC的掩码序列共可指示N^2个信息属性,其中符号^表示乘方运算。当然,图8仅是一种示例, 当每个D2D数据包括M个编码段时,则M编码段的CRC的掩码序列共可指示N^M个信息属性。示例性的,CRC的掩码有2种掩码序列,则两个编码段的CRC可指示2^2=4个信息属性。如表2,示出了CRC中的掩码序列和序号的对应关系:
序号 掩码序列
0 000000000000000000000000
1 111111111111111111111111
2 101010101010101010101010
3 010101010101010101010101
4 110011001100110011001100
5 001100110011001100110011
6 111100001111000011110000
7 000011110000111100001111
表4
其中,以上表4中各掩码序列之间间隔为预设的汉明距离,其中上表中序号0和序号1之间掩码序列的汉明距离为24;其他各序号之间最小汉明距离为12。当然这只是一种示例,本发明的方案不限于上述表2。
使用上面8个掩码序列,针对2个编码段的情况,共可指示8*8=64个信息属性。当然如果不需要这么多信息属性,可以选择8个序列中的部分掩码序列,当信息属性为传输层级时,示例性的:前两个序列0、1,共可指示2*2=4个传输层级。
具体的如以下示例:
第一个编码段的CRC的掩码对应的掩码序列的序号是0,第二个编码段的CRC的掩码对应的掩码序列的序号是0,则代表传输层级是0;
第一个编码段的CRC的掩码对应的掩码序列的序号是0,第二个编码段的CRC的掩码对应的掩码序列的序号是1,则代表传输层 级是1;
第一个编码段的CRC的掩码对应的掩码序列的序号是1,第二个编码段的CRC的掩码对应的掩码序列的序号是0,则代表传输层级是2;
第一个编码段的CRC的掩码对应的掩码序列的序号是1,第二个编码段的CRC的掩码对应的掩码序列的序号是1,则代表传输层级是3。以上仅仅是提供了一种示例,本发明的方案不限于上述示例。
当信息属性为优先级时,示例性的:前两个序列0、1,共可指示2*2=4个优先级。
具体的如以下示例:
第一个编码段的CRC的掩码对应的掩码序列的序号是0,第二个编码段的CRC的掩码对应的掩码序列的序号是0,则代表优先级是0;
第一个编码段的CRC的掩码对应的掩码序列的序号是0,第二个编码段的CRC的掩码对应的掩码序列的序号是1,则代表优先级是1;
第一个编码段的CRC的掩码对应的掩码序列的序号是1,第二个编码段的CRC的掩码对应的掩码序列的序号是0,则代表优先级是2;
第一个编码段的CRC的掩码对应的掩码序列的序号是1,第二个编码段的CRC的掩码对应的掩码序列的序号是1,则代表优先级是3。以上仅仅是提供了一种示例,本发明的方案不限于上述示例。
当信息属性为来源时,示例性的:前两个序列0、1,还可以指示来源。
具体的如以下示例:
第一个编码段的CRC的掩码对应的掩码序列的序号是0,第二个编码段的CRC的掩码对应的掩码序列的序号是0,则代表发送设备位于小区覆盖范围内,或者信息来自于小区覆盖范围内;
第一个编码段的CRC的掩码对应的掩码序列的序号是1,第二个编码段的CRC的掩码对应的掩码序列的序号是1,则代表发送设备位于小区覆盖范围外,或者信息来自于小区覆盖范围外;以上仅仅是提供了一种示例,本发明的方案不限于上述示例。
