Description

一种信号传输的方法及终端
本申请要求在2014年5月08日提交中国专利局、申请号为201410193532.1、发明名称为“一种信号传输的方法及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种信号传输的方法及终端。
背景技术
传统的蜂窝通信技术中，终端(UE)之间的数据通信流程如图1所示，两个终端的语音、数据等业务通过各自驻留的基站(eNB)以及核心网(服务网关(SGW)和分组数据网关(PGW))进行交互。
设备到设备(Device-to-Device，D2D)通信，即终端直通技术，是指邻近的终端可以在近距离范围内通过直连链路进行数据传输的方式，不需要通过中心节点(即基站)进行转发，如图2所示。
D2D技术本身的短距离通信特点和直接通信方式使其具有如下优势：
1、终端近距离直接通信方式可实现较高的数据传输速率、较低的传输延迟和较低的功耗；
2、利用网络中广泛分布的用户终端以及D2D通信链路的短距离特点，可以实现频谱资源的有效利用；
3、D2D的直接通信方式能够满足如无线点对点(P2P)等业务的本地数据共享需求，提供具有灵活适应能力的数据服务；
4、D2D直接通信能够利用网络中数量庞大且分布广泛的通信终端以拓展网络的覆盖范围。
由于D2D系统中，发送UE位置的不确定性，对于一个接收UE来说，不同发送UE发送的信号到达接收UE时候，其路径损耗的差值可能非常大，从而由于带内泄露的问题导致“远-近”效应问题。具体如图3所示，例如：接收UE(Rx UE)正在接收Tx UE1的信号，并且由于信道衰落的影响，Tx UE1的信道到达Rx UE的信号强度是-100分贝毫瓦(dBmW)，同时位于Rx UE附近的Tx UE2也同时发起一个D2D通信，并且Tx UE2的信号到达Rx UE的信号强度是-60dBmW，这时即便Tx UE1和Tx UE2发送信号在频率上是正交的，由于带内泄露的影响，Tx UE1的信号会受到较强的来自Tx UE2的带内泄露的影 响，从而导致Tx UE1的信号无法正确接收。
D2D传输会受到带内泄露干扰的影响，“远近”效应导致带内泄露干扰的影响更加严重。带内泄露干扰是指由于误差向量幅度(EVM)、功放非线性等非理想因素导致的信号功率到相邻频带的泄露。
如何有效降低终端在信号传输过程中的带内泄露干扰，成为需要解决的问题。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
以下各实施例中，时间单元包括但不限于子帧、时隙、发送机会，以下实施例中，仅以子帧作为时间单元为例进行说明，对于其它时间单元可以采用相同的实施方式。
以下各实施例中，子带可以是逻辑子带，也可以是物理子带。其中逻辑子带可通过一定的映射关系映射到物理子带。
例如，逻辑子带n映射到物理子带n。
又例如，逻辑子带n映射到物理子带(n+ceil(N/4))mod N，其中N是子带的个数，ceil(x)表示不小于x的最小正整数。
逻辑子带到物理子带的映射关系还可以是时变的。例如，逻辑子带n映射到物理子带(n+k+ceil(N/4))mod N，其中k是子帧编号。又例如，逻辑子带n映射到物理子带(n+ceil(kN/4))mod N。
如图4所示，终端在一个资源池内的一部分资源上进行信号传输，该信号传输可以是D2D信号的传输，也可以是蜂窝信号的传输。其中，资源池由一些时频资源构成，该时频资源具有一定的时间范围和一定的频率范围，并且资源池中的时频资源可以是以一定的周期在时域内重复出现。
图4所示的资源池在时间和频域内都是连续的，实际上资源池也可以是由不连续的时频资源构成。图4所示的资源池在时域内包括NT个子帧，在频域内包括NF个子带。一个子带的带宽可以是一个物理资源块(Physical Resource Block,PRB)的整数倍，例如子带带宽为1个PRB带宽，为180k赫兹(Hz)，或者子带带宽为2个PRB带宽，为360kHz，以此类推。
终端可以占据一个子带进行数据传输，例如，图4中UE1占用子带0，UE2占用子带 1进行传输。终端也可以占据多个子带进行传输，例如UE3占用子带2和子带3进行传输。
终端在一个子带进行数据传输时，可以只在时域资源中的一部分子帧内进行传输，例如，在子帧0,2,4,6内传输，其他的子帧不传输任何信号。本申请实施例中，采用时域模式来表示终端进行信号传输的子帧集合，不同的时域模式对应着不同的子帧集合，如图5中，模式0对应着在子帧0,2,4,6内传输信号，模式1对应着在子帧1,3,5,7内传输信号，模式2对应着在子帧0,1,2,3内传输信号，模式3对应着在子帧4,5,6,7内传输信号。
第一实施例中，如图6所示，作为发送端的终端进行信号发送的详细方法流程如下：
步骤601：终端确定子带以及时域模式，确定的时域模式属于确定的子带相关联的时域模式集合，每个时域模式对应终端进行信号传输的时间单元的集合。
其中，每个时域模式对应终端进行信号传输的时间单元的不同组合。
优选地，不同的子带对应的不同的时域模式集合，各时域模式集合中包含的时域模式不同。
具体地，终端确定子带至少可以有以下两种具体实现方式：
终端从预设的频域资源中任意选择一个或多个子带作为进行信号传输的子带；
或者，
终端根据第一测量结果，从预设的频域资源中确定一个或多个子带作为进行信号传输的子带；
或者，
终端根据网络侧设备的配置信息确定一个或者多个子带。
其中，网络侧设备可以是基站、移动性管理实体(MME)等。
其中，第一测量结果通过对预设的频域资源包含的每个子带上传输的信号进行测量获得。在一个具体实施中，测量预设的频域资源包含的各子带上的接收信号功率作为第一测量结果，选择各接收信号功率中的最小值对应的子带作为进行信号传输的子带。
优选地，根据时域模式集合的实现形式的不同，有以下三种具体实施方式，具体如下：

终端从确定的子带相关联的时域模式集合中任意选择一个时域模式作为信号传输的时域模式；
或者，
终端根据第二测量结果，从确定的子带相关联的时域模式集合中选择一个时域模式；
或者，
终端接收网络侧设备的配置信息确定时域模式。
其中，网络侧设备可以是基站、移动性管理实体(MME)等。
其中，第二测量结果通过对确定的子带相关联的时域模式集合中的各时域模式上传输的信号进行测量获得。
在一个具体实施中，测量确定的子带相关联的时域模式集合中的每个时域模式上的接收信号功率作为第二测量结果，选择各接收信号功率中的最小值所对应时域模式作为信号传输的时域模式。
其中，时域模式上的接收信号功率包括但不限于：
在该时域模式对应的进行数据传输的时间单元(如子帧)上进行测量得到的接收信号功率；或者，在该时域模式对应的进行数据传输的时间单元(如子帧)上测量得到的接收信号功率进行平均后得到的平均接收信号功率。
第二种实施方式中，终端从子带时域模式组合的集合中确定一个子带时域模式组合，获取子带时域模式组合中包含的子带以及时域模式，其中，子带时域模式组合的集合中包含所有可能的子带时域模式组合，每个子带时域模式组合中包含有一个子带及与该子带相关联的一个时域模式。
该实施方式中，同一子带所对应的一个或多个子带时域模式组合中的各时域模式构成该子带所对应的时域模式集合，也就是说，子带只能与相关联时域模式集合中的时域模式构成子带时域模式组合。一个子带时域模式组合即可确定数据传输的时域资源和频域资源。
该实施方式中，终端确定一个子带时域模式组合至少可以有以下三种具体实现：

在一个具体实施中，测量预设的频域资源所包含的每个子带所对应的每个时域模式上的接收信号功率作为第三测量结果，根据接收信号功率中的最小值所对应的子带以及时域模式，确定进行信号传输的子带时域模式组合。
第三种实施方式中，终端确定子带以及子带的标识，根据预设的子带的标识与伪随机序列初始值的映射关系，获取确定的子带的标识对应的伪随机序列初始值，并根据确定的伪随机序列初始值以及预设的伪随机序列的初始值与伪随机序列之间的映射关系，确定伪 随机序列，根据伪随机序列确定时域模式所包含的各时间单元。
其中，根据预设的子带的标识与伪随机序列初始值的映射关系，获取确定的子带的标识对应的伪随机序列初始值时，可以是直接根据子带的标识确定伪随机序列初始值，也可以是根据预设的子带的标识与伪随机序列初始值参数的映射关系，获取确定的子带的标识对应的伪随机序列初始值参数后，根据预设的伪随机序列初始值参数与伪随机序列初始值之间的映射关系，获取确定的子带的标识对应的伪随机序列初始值。
伪随机序列初始值参数包括但不限于伪随机序列的初始值、形成伪随机序列的初始值的参数、伪随机序列初始值集合中的伪随机序列初始值对应的索引值中的任意一种或任意组合。
步骤602：终端向接收端发送控制信息以及在确定的子带上、按照确定的时域模式指示的时间单元向接收端发送信号。
其中，终端发送的控制信息用于接收端确定接收信号的时频资源，终端发送信号时按照步骤601中确定的子带以及时域模式向接收端发送信号。
优选地，控制信息至少用于指示确定的子带的标识。
其中，终端可以在向接收端发送信号的同时发送控制信息，该控制信息可以携带在向接收端发送的信号中。
终端也可以在向接收端发送信号之前发送控制信息。并且，可以采用与确定的时频资源不同的资源发送控制信息。
优选地，若确定的子带相关联的时域模式集合中包含有一个以上时域模式，控制信息还用于指示确定的时域模式的时域模式指示信息，该时域模式指示信息用于唯一确定一个时域模式。
其中，时域模式指示信息至少为确定的时域模式在所属时域模式集合中所对应的索引值、伪随机序列的初始值、形成伪随机序列的初始值的参数、伪随机序列初始值集合中伪随机序列初始值对应的索引值中的任意一种或者任意组合。本领域技术人员应该明白，此处仅为举例，本申请的保护范围并不以此为限，对于其它能够唯一确定时域模式的参数也可以作为时域模式指示信息，且在本申请的保护范围之内。
具体实施中，终端可以在发送给接收端的控制信息中携带时域模式指示信息；
或者，
确定传输控制信息所占用的控制信道的资源位置，由接收端在接收控制信息时确定该控制信息所占用的控制信息的资源位置，根据预设的时域模式指示信息与控制信道的资源位置的对应关系，确定时域模式指示信息，进而根据该时域模式指示信息确定时域模式。
具体实施中，终端可以在发送给接收端的控制信息中携带子带标识的指示信息；
或者，
确定传输控制信息所占用的控制信道的资源位置，由接收端在接收控制信息时确定该控制信息所占用的控制信息的资源位置，根据预设的子带标识的指示信息与控制信道的资源位置的对应关系，确定子带标识的指示信息。
本申请实施例中，每个时域模式所对应的时间单元可以是包含在固定长度的时域资源内，或者，包含在可变时间长度的时域资源内。
在一个优选地实施方式中，子带相关联的时域模式集合中的时域模式所包含的各时间单元由伪随机序列确定，伪随机序列由伪随机序列的初始值根据预设的映射关系映射后获得。
具体地，伪随机序列可以由伪随机序列初始值确定，该伪随机序列的初始值根据子带的标识、终端的标识、接收端的标识、时域模式在所属时域模式集合中对应的索引值中的任意一种或者任意组合确定。
基于同一发明构思，第二实施例中，如图7所示，作为接收端的终端进行信号接收的详细方法流程如下：

其中，根据子带的标识确定时域模式，至少可以有以下两种具体实现方式：
第一种实现方式中，终端根据预设的子带的标识与时域模式的映射关系，获取子带对应的时域模式。
例如，子带0映射的时域模式为{0,1,2,3}，即在子帧0,1,2,3上进行数据传输，子带1映射的时域模式为{4,5,6,7}，即在子帧4,5,6,7上进行数据传输。
第二种实现方式中，终端根据预设的子带的标识与伪随机序列初始值的映射关系，获取确定的子带的标识对应的伪随机序列初始值，并根据确定的伪随机序列初始值以及预设的伪随机序列的初始值与伪随机序列之间的映射关系，确定伪随机序列，根据伪随机序列确定时域模式所包含的各时间单元。
例如标识为i的子带映射的伪随机序列初始值为cinit,0＝i。
第二具体实施中，若确定的子带关联的时域模式集合中包含有一个以上时域模式，控制信息至少用于指示子带的标识以及时域模式指示信息，该时域模式指示信息用于唯一确 定一个时域模式，根据控制信息确定子带的标识以及子带，以及根据控制信息确定时域模式。
其中，根据控制信息所指示的子带的标识以及时域模式指示信息确定时域模式，至少可以有以下三种具体实现：
第一种实现方式中，若时域模式指示信息为时域模式在所属时域模式集合中对应的索引值，根据预设的时域模式指示信息与时域模式的对应关系，从与发送端通知的子带的标识确定的子带相关联的时域模式集合中，获取与发送端通知的时域模式指示信息对应的时域模式，作为接收信号的时域模式。
例如，子带0关联的时域模式集合包括两个时域模式{0,1,2,3}和{4,5,6,7}，其索引值分别为0和1，如果时域模式指示信息取值为0，则终端确定时域模式为{0,1,2,3}，如果时域指示信息取值为1，则中终端确定时域模式为{4,5,6,7}。
第二种实现方式中，若时域模式指示信息为伪随机序列初始值参数，根据预设的伪随机序列初始值与伪随机序列初始值参数以及子带的标识之间的映射关系，确定时域模式指示信息对应的伪随机序列初始值，根据确定的伪随机序列初始值以及预设的伪随机序列的初始值与伪随机序列之间的映射关系，确定伪随机序列，根据所述伪随机序列确定所述时域模式所包含的各时间单元。
其中，具体是确定时域模式指示信息及子带的标识信息对应的伪随机序列初始值。
第三种实现方式中，若时域模式指示信息为伪随机序列初始值参数，根据预设的伪随机序列初始值与伪随机序列初始值参数之间的映射关系，确定时域模式指示信息对应的伪随机序列初始值，根据确定的伪随机序列初始值以及预设的伪随机序列的初始值与伪随机序列之间的映射关系，确定伪随机序列，根据伪随机序列确定时域模式所包含的各时间单元。
例如，时域模式指示信息取值为m，则子带i的伪随机序列初始值为cinit＝210·i+m。
一个具体实施中，预设的伪随机序列初始值与伪随机序列初始值参数以及子带的标识之间的映射关系中还可以包括终端自身的标识信息或作为发送端的终端的标识信息NID。
例如，时域模式指示信息取值为m，终端自身的标识信息为NID，则子带i的伪随机序列初始值为cinit＝216·NID+210·i+m
以上具体实施中，伪随机序列初始值参数包括但不限于伪随机序列的初始值、形成伪随机序列的初始值的参数、伪随机序列初始值集合中的伪随机序列初始值对应的索引值中的任意一种或任意组合。本领域技术人员应该明白，此处仅为举例，本申请的保护范围并不以此为限，对于其它能够确定伪随机序列初始值的参数也可以作为伪随机序列初始值参数，且在本申请的保护范围之内。
步骤702：终端在确定的子带上、按照确定的时域模式所指示的时间单元接收信号。
其中，作为接收端的终端只在确定的时域模式所指示的时间单元(如子帧)上进行信号接收。
第一、第二实施例中，每个子带关联的时域模式集合有以下两种具体实现方式：
第一种实现方式中，每个时域模式所对应的时间单元包含在固定长度的时域资源内，即针对一个固定的时间长度，该时间长度内包含有设定个数的时间单元(如子帧)，每个时域模式描述该时间长度内的数据传输情况。
其中，不同的子带关联的时域模式集合中包含的时域模式的个数可以相同，也可以不同。并且，每个子带关联的时域模式集合中包含的时域模式的个数可以是一个或多个。
例如，如图8所示，每个时域模式覆盖8个子帧，即该时域模式用来描述8个子帧上的数据传输情况。假设每个子带关联的时域模式集合包括两个模式，模式0和模式1。其中，子带0关联的模式0在子帧0,2,4,6上进行传输，子带0关联的模式1在子帧1,3,5,7上进行传输；子带1关联的模式0在子帧0,1,4,5上进行传输，子带1关联的模式1在子帧2,3,6,7上进行传输；子带2关联的模式0在子帧0,3,4,7上进行传输，子带2关联的模式1在子帧1,2,5,6上进行传输；子带3关联的模式0在子帧0,1,2,3上进行传输，子带3关联的模式1在子帧4,5,6,7上进行传输。
第二种实现方式中，每个时域模式所对应的时间单元包含在可变时间长度的时域资源内。
优选地，子带相关联的时域模式集合中的时域模式所包含的各时间单元的由伪随机序列确定，伪随机序列由伪随机序列的初始值根据预设的映射关系映射后获得。
其中，伪随机序列的初始值根据子带的标识、发送端的标识、接收端的标识、时域模式在所属时域模式集合中对应的索引值中的任意一种或者任意组合确定。
具体地，伪随机序列确定时域模式所包含的各时间单元的有多种实现方式，举例如下：
实现一，子带标识(如编号)为i的子带的伪随机序列初始值为cinit,0＝2·i和cinit,1＝2·i+1，这两个随机序列初始值根据预设的映射关系映射后可以生成两个伪随机序列。伪随机序列的每一个比特位对应一个子帧，如果该比特位取值为1，则对应的子帧可以进行数据传输，如果该比特位取值为0，则对应的子帧不进行数据传输。由于伪随机序列的长度可以无限扩展，其可以实现可变时间长度的时域模式。其中，子带编号为i的子带对应两个伪随机序列初始值，则该子带关联的时域模式集合中包括两个时域模式。如果与一个子带关联的时域模式集合中只有一个元素，则该子带的伪随机序列只需要有1个取值，例如cinit＝i或者cinit＝210·NID+i。
实现二，子带标识(如编号)为i的子带的伪随机序列初始值为cinit＝i，由该伪随机序列初始值根据预设的映射关系映射后可以生成一个伪随机序列，对该伪随机序列的每一比特位取反(如‘0’取反是‘1’，‘1’取反是‘0’)，得到另外一个伪随机序列，由这两 个伪随机序列确定两个时域模式。
实现一和实现二中，伪随机序列初始值可以是子带标识(编号)的其它函数，如cinit＝210·i。
实现三，子带标识(如编号)为i的子带的伪随机序列初始值为cinit,0＝210·NID+2·i和cinit,1＝210·NID+2·i+1，其中，NID是终端的标识，该终端可以是数据发送端，也可以是数据接收端。由两个初始值根据预设的映射关系映射后生成伪随机序列，进而确定时域模式的方法与实现一和实现二相同。
该实现中，子带标识(编号)为i的子带对应两个伪随机序列初始值，从而该子带关联的时域模式集合中包括两个时域模式。
实现四，如果要在一个子带关联的时域模式集合中包括M个时域模式，则子带标识(如编号)为i的子带的伪随机序列初始值为可以表示为：cinit,m＝210·NID+25·i+m，m＝0,1,2...,M-1，其中，NID是终端的标识，m表示时域模式在所属时域模式集合中对应的索引值可以得到M个伪随机序列初始值，进而可以根据该M个伪随机序列初始值根据预设的映射关系映射后生成M个伪随机序列，得到M个时域模式。
实现五，子带编号为i的子带的伪随机序列初始值为cinit＝210·NID+i，其中，NID表示终端的标识，可以是数据发送端的标识，也可以是数据接收端的标识。由该伪随机序列初始值根据预设的映射关系映射后可以生成一个伪随机序列，对该伪随机序列的每一比特位取反(‘0’取反是‘1’，‘1’取反是‘0’)，得到另外一个伪随机序列，由该两个伪随机序列确定两个时域模式。
实现六，如果要在一个子带关联的时域模式集合中包括M个时域模式，则子带标识(如编号)为i的子带的伪随机序列初始值为可以表示为：cinit,m＝210·NID+km，m＝0,1,2...,M-1，其中，NID是终端的标识，m表示时域模式在所属时域模式集合中对应的索引值可以得到M个伪随机序列初始值，km是整数且km属于由M个整数构成的集合Ki，进而可以根据该M个伪随机序列初始值根据预设的映射关系映射后生成M个伪随机序列，得到M个时域模式。
以上各实现中，由伪随机序列初始值根据预设的映射关系映射确定伪随机序列可以有多种方式，本申请实施并不做限制，现有技术中存在的各种伪随机序列初始值根据预设的映射关系映射确定伪随机序列的方式都适用于本申请。
例如，映射生成M序列，假设M序列的寄存器长度为L，则每个寄存器的初始状态与伪随机序列初始值的关系为：
Figure PCTCN2015078463-appb-000001
其中x(n)为第n个寄存器的初始状态，取值为0或者1，cinit为伪随机序列的初始值。
又例如，根据伪随机序列初始值映射生成Gold序列。
