设备到设备通信中的数据接收方法、发送方法及设备
相关申请的交叉引用
本申请主张在2014年8月7日在中国提交的中国专利申请号No.201410386994.5的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种设备到设备(Device to Device,D2D)通信中的数据接收方法、发送方法及设备。
背景技术
传统的蜂窝通信技术中,两个终端之间的数据通信流程如图1所示,两个终端之间的语音和数据等业务经过各自驻留的基站(普通基站或演进型基站)以及核心网进行交互。
D2D通信,即终端直通技术,是指邻近的终端(UE)可以在近距离范围内通过直连链路进行数据传输,不需要中心节点(如基站)转发,如图2所示。
D2D通信具有如下优势:
1、终端近距离直接通信方式可实现较高的数据传输速率、较低的时延和较低的功耗;
2、利用网络中广泛分布的通信终端以及D2D通信链路的短距离特点,可有效利用频谱资源;
3、D2D的直接通信方式能够适应如无线端到端(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。
D2D的应用场景主要有以下四种,分别如图3a、图3b、图3c和图3d所示,各个场景可以组合出现。D2D通信中的UE1和UE2可以位于网络覆盖范围内,也可以是位于网络覆盖范围之外,UE1和UE2可以互为发送方和接 收方。在图3a所示的场景中,UE1和UE2均处于网络覆盖范围之外;在图3b所示的场景中,UE1在网络覆盖范围之内,UE2在网络覆盖范围之外;在图3c所示的场景中,UE1和UE2在同一基站的覆盖范围之内;在图3d所示的场景中,UE1和UE2位于不同基站的覆盖范围之内。
在D2D通信中,除了用户之间的一对一通信方式之外,典型的应用场景还包括D2D的群组或广播通信,该场景可用于公共安全应用中的消防、救援和反恐等。
现有技术中,网络覆盖范围之内的UE按照网络配置的资源池配置信息发送和接收数据,网络覆盖范围之外的UE按照预定义的资源池配置信息发送和接收数据。若D2D通信为部分网络覆盖场景或者为不同小区覆盖场景,UE在不知道对端UE采用哪种资源池配置信息的情况下,如何接收对端UE的数据,目前没有解决方案。

具体实施方式
为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开作进一步地详细描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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,都属于本公开保护的范围。
如图4所示,本公开实施例中,D2D通信中接收端UE进行数据接收的详细方法流程如下:
步骤401:接收端UE采用本地保存的每个资源池配置信息检测发送端发送的控制信息。
本公开实施例中,接收端UE根据资源池配置信息中所配置的可用于控制信息发送的资源,采用盲检测的方法检测控制信息,该过程与物理下行控 制信道(PDCCH)的盲检测类似。
一个具体实现方式中,在资源池配置信息中所配置的所有资源上盲检测控制信息;另一个具体实现方式中,按照预定义的规则在资源池配置信息中所配置的一部分资源上检测控制信息。
可选地,UE按照设定的时间周期更新本地保存的资源池配置信息,若UE在设定的时间周期内未接收到某资源池配置信息,则将该资源池配置信息从本地保存的资源池配置信息列表中删除。
可选地,接收端UE本地保存的资源池配置信息按照来源区分可以是预先配置的资源池配置信息、基站指示的资源池配置信息和其它UE指示的资源池配置信息中的任意一个或多个。
具体地,不同的基站指示的资源池配置信息不同。
其中,其它UE指示的资源池配置信息可以是一个或多个。
具体地,若UE位于网络覆盖范围外,该UE自身预先配置有资源池配置信息;若UE位于基站覆盖范围内,该UE接收基站指示的资源池配置信息,或者,接收由其他UE中继转发的基站指示的资源池配置信息;不管UE是否位于网络覆盖范围之内,该UE都可以接收其它UE转发的一个或多个资源池配置信息,其它UE转发的资源池配置信息可以是归属的基站指示的资源池配置信息。
可选地,资源池配置信息中包括但不限于:
时频资源指示信息,和/或跳频指示信息,和/或循环前缀(CP)长度指示信息。
可选地,资源池配置信息由用于控制信息的控制资源池配置信息和用于数据信息的数据资源池配置信息组成。
其中,若控制信息传输采用的跳频方式与数据信息传输采用的跳频方式不相同,则跳频指示信息可包括控制信息传输的跳频指示信息和数据信息传输的跳频指示信息,控制信息传输的跳频指示信息位于控制资源池配置信息中,数据信息传输的跳频指示信息位于数据资源池配置信息中;若控制信息传输采用的跳频方式与数据信息传输采用的跳频方式相同,无需单独指示控制信息传输的跳频指示信息和数据信息传输的跳频指示信息。
同理,若控制信息传输采用的时频资源与数据信息传输采用的时频资源不相同,时频资源指示信息包括:
位于所述控制资源池配置信息中的控制信息传输的时频资源指示信息,和位于所述数据资源池配置信息中的数据信息传输的时频资源指示信息;
若控制信息传输采用的CP长度与数据信息传输采用的CP长度不相同,所述CP长度指示信息包括:
位于所述控制资源池配置信息中的控制信息传输的CP长度指示信息,和位于所述数据资源池配置信息中的数据信息传输的CP长度指示信息。
其中,时频资源指示信息包括但不限于:D2D传输子帧的指示信息和/或频率资源位置的指示信息。
步骤402:接收端UE根据检测到的控制信息确定发送端所采用的资源池配置信息。
可选地,UE根据检测到的控制信息确定发送端所采用的资源池配置信息的方式有多种,包括但不限于以下列举的方式:
第一种方式,获取检测到的控制信息的指定比特位携带的标识信息,将该标识信息对应的资源池配置信息确定为发送端所采用的资源池配置信息。
第二种方式,获取检测到的传输控制信息所采用的解调用参考信号(DMRS)序列中携带的标识信息,将该标识信息对应的资源池配置确定为发送端所采用的资源池配置信息。
第三种方式,获取检测到的控制信息的传输资源的位置,根据预设的传输资源的位置与资源池配置信息的对应关系,将与该传输资源的位置对应的资源池配置信息确定为发送端采用的资源池配置信息。
具体地,该第三种方式中,可以是获取检测到的控制信息的重传模式,根据预设的重传模式与资源池配置信息的对应关系,将与该重传模式对应的资源池配置信息确定为发送端采用的资源池配置信息。
可选地,第一种、第二种方式中,若资源池配置信息源于小区或网络覆盖范围内的UE,标识信息为与小区标识关联的标识;
若资源池配置信息源于网络覆盖范围外的UE,标识信息为预设值。
其中,与小区标识关联的标识可以直接为小区标识,也可以是根据小区 标识采用预定规则计算得到的标识信息。
步骤403:接收端UE根据确定的资源池配置信息以及检测到的控制信息接收该发送端的数据信息。
接收端UE根据确定的资源池配置信息确定发送端的数据信息占用的资源,在该确定的资源上按照控制信息的指示接收发送端的数据信息。
该实施例中,接收端UE采用本地保存的每个资源池配置信息检测发送端发送的控制信息,根据检测到的控制信息确定发送端所采用的资源池配置信息,从而能够根据确定的资源池配置信息以及检测到的控制信息接收发送端的数据信息。
基于同一发明构思,本公开实施例中,如图5所示,D2D通信中发送端UE进行数据发送的详细方法流程如下:
步骤501:UE从至少一个资源池配置信息中确定一个资源池配置信息。
可选地,至少一个资源池配置信息按照来源区分包括:预先配置的资源池配置信息、基站指示的资源池配置信息和其它UE指示的资源池配置信息中的任意一个或多个。
可选地,若UE位于网络覆盖范围之外,将预先配置的资源池配置信息确定为所述资源池配置信息;
