Description

D2D通信方法及设备 技术领域
本发明涉及D2D通信领域，特别涉及一种D2D通信方法及设备。
背景技术
近年来设备到设备(Device to Device，D2D)通信越来越受到人们的关注，D2D通信不仅可以应用于车车通信、车与路边单元之间的通信，还可以应用于人车之间的通信等多种场景，用以提高道路交通的安全性、可靠性，提升交通通行效率。
D2D通信根据其传输模式的不同，具体分为D2D发现模式(即D2D discovery模式)和D2D通信模式(即D2D communication模式)。在D2D communication模式中，数据发送采用调度分配(Schedulling Assignment，SA)+DATA(业务数据)模式。用户设备有业务数据需要发送时，首先发送一个SA信息，SA信息指示从发送端发出的业务数据的时频资源位置、编码方式等。作为接收端的用户设备成功接收到并解码SA信息后，会在SA信息指示的时频资源位置上接收相应的业务数据，并按SA信息指示的编码方式进行解码。
为了接收到SA信息，接收端需要在SA资源池内进行盲检测。然而，由于SA信息的可能传输资源是SA资源池内的任意一个物理资源块(Physical Resource Block，PRB)位置，因此，如果系统带宽超过10M Hz(对应50个PRB)，接收端需要盲检测SA的次数就会超过50次，导致接收端检测的复杂度较高，且功耗也较大。

图9是本发明实施例提供的一种基站的结构示意图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
图1是本发明实施例提供的一种实施场景示意图。参见图1，该实施场景中包括用户设备(User Equipment，UE)和基站，其中，本发明实施例中所提供的UE可以是指车载通信系统、车辆上安装的用户设备或者一些如智能手机或者手持设备等的车内用户所持有的用户设备，或者是行人和骑车人的手持终端设备和可穿戴设备，如智能手表、智能头盔等。基站可以是指具有无线资源的管理功能的设备，能够与用户设备进行通信，或者作为中央控制器协助用户设备之间进行直接通信。
为了使得用户设备获知可用频域资源位置，基站可以在资源池配置信息中携带频域资源位置信息和时域资源位置信息，其中，时域资源位置信息可以沿用现有的资源池配置方式，以两种参数来表示，分别为：timeOffsetIndicator:时域资源偏移指示；subframeBitmap:子帧位图信息。
而在本发明实施例中，该频域资源位置信息包括连续两个D2D资源的频域间隔和频域资源偏移指示，下面分别对该两项参数进行介绍：
(1)连续两个D2D资源的频域间隔。
该连续两个D2D资源的频域间隔可以采用频域资源粒度的任一表示形式为单位。例如，对于SA资源池来说，连续两个SA资源的频域间隔以PRB或子带为单位。其中，子带是指一些连续PRB的集合。当然，对于业务数据资源池来说，连续两个业务数据资源的频域间隔也可以PRB或子带为单位。
需要说明的是，所述连续两个D2D资源的频域间隔可以是预配置的、基站配置的或根据系统带宽确定。该预配置以及基站配置是一种显示配置，直接以数值等形式表示，而由系统带宽决定可以看做是一种隐式配置，即预先设置系统带宽与频域间隔之间的对应关系，如，10MHz系统带宽对应的频域间隔为1，20MHz系统带宽对应的频域间隔为2，则如果当前系统带宽为10MHz，则确定该连续两个D2D资源的频域间隔为1。
上述连续两个D2D资源的频域间隔对于不同类型的D2D数据，可以有不同的解释，如，对于SA信息来说，该两个D2D资源的频域间隔可以是指连续两个用于传输调度分配SA信息的物理资源块之间的频域间隔；对于业务数据来说，该两个D2D资源的频域间隔可以是指连续两个用于传输业务数据的物理资源块集合中的第一个物理资源块之间的频域间隔。业务数据可以传输于由多个连续的物理资源块构成的物理资源块集合，因此，此处的频域间隔可以是指用于传输业务数据1的物理资源块集合中的第一个物理资源块与用于传输业务数据2的物理资源块集合中的第一个物理资源块之间的频域间隔。
(2)频域资源池指示。该频域资源池指示有以下至少两种表示方式：
第一种表示方式、以频域资源偏移指示来表示。
该频域资源偏移指示可以采用频域资源粒度的任一表示形式为单位。例如，所述频域资源偏移指示以PRB(物理资源块)或子带为单位。
进一步地，所述频域资源偏移指示的参考位置为系统带宽起始位置，如第 一个PRB，或，该频域资源偏移指示的参考位置为系统带宽结束位置，如最后一个PRB。
假如，以系统带宽起始位置为参考位置，且以PRB为频域资源偏移指示的单位，则对于频域资源偏移指示为4的情况下，可以确定频域资源池的起始位置为系统带宽起始位置之后的第4个PRB。
参见图2，该图2是本发明实施例提供的一种时频资源示意图。其中，横轴t用于表示时域资源，纵轴f用于表示频域资源，其中，频域资源偏移指示FreqOffsetIndicator用于指示D2D资源基于参考位置的频域偏移，该频域资源偏移指示可以看做是D2D资源在频域上的起始位置或结束位置。
第二种表示方式、以可用频域资源的起始位置和结束位置来表示。
在第二种表示方式中，该频域资源的起始位置和结束位置可以采用PRB索引等方式表示。
参见图3，该图3是本发明实施例提供的一种时频资源示意图。其中，横轴t用于表示时域资源，纵轴f用于表示频域资源，其中，频域资源的起始位置(PRB_start)和结束位置(PRB_end)用于指示D2D资源所在的频域范围。
下面，仅以采用第一种表示方式来表示SA资源池为例进行说明，图4是本发明实施例提供的一种D2D通信方法的流程图。参见图4，包括：
400、基站向UE发送资源池配置信息，该资源池配置信息包括频域资源位置信息和时域资源位置信息，该频域资源位置信息包括频域资源偏移指示和连续两个SA资源的频域间隔。
其中，该资源池配置信息可以携带于基站的系统广播消息或其他信令中，如RRC(Radio Resource Control，无线资源控制协议)信令、公共控制信令等，本发明实施例对此不做具体限定。
401、UE接收该资源池配置信息。
需要说明的是，具体该资源池配置信息携带在何种信令中，可以由系统预先配置，从而UE可以在接收到该信令时，从信令中提取该资源池配置信息。
频域资源偏移指示是相对于系统带宽起始位置还是结束位置可以由系统预先配置，从而UE在接收到该频域资源指示时，可以结合系统带宽确定可用频域资源所在的频域范围。
402、UE根据该资源池配置信息，确定可用频域资源。
由于已经获知了频域资源偏移指示和连续两个SA资源的频域间隔，可以获知哪些频域资源可能用于传输D2D数据。
其中，该步骤402可以具体包括以下步骤402A至步骤402B：
402A、该UE根据系统带宽内的物理传输块总数以及频域资源偏移指示，确定可用频域资源所在频域范围。
例如，当系统带宽内的物理传输块总数为100个、且频域资源偏移指示为4时，则可以确定频域资源所在频域范围在PRB索引为4至99的PRB。
402B、该UE根据该可用频域资源所在频域范围和连续两个SA资源的频域间隔，确定可用频域资源位置。
基于上述例子，如果连续两个SA资源的频域间隔为4，且单位为PRB时，则可以确定可用频域资源位置，也即是可用于SA传输的PRB为：4,8,12,16…以此类推。
另外，该步骤402还可以采用以下过程以确定可用频域资源：
如果所述频域资源偏移指示的参考位置为系统带宽起始位置，应用下述公式一，
公式一：Mod(m-FreqOffsetIndicator，InterDis)＝0；
如果所述频域资源偏移指示的参考位置为系统带宽结束位置，应用下述公式二，
公式二：Mod(N-1-FreqOffsetIndicator-m，InterDis)＝0；
其中，m为可用频域资源所在物理资源块PRB的索引，m为小于N的整数，N为系统带宽内的PRB总数，FreqOffsetIndicator为频域资源偏移指示，InterDis为连续两个设备到设备D2D资源的频域间隔。
以上述公式一为例，
例如：FreqOffsetIndicator＝0；InterDis＝4；系统中可用于SA传输的PRB为：0,4,8,12….
例如：FreqOffsetIndicator＝8；InterDis＝2；系统中可用于SA传输的PRB为：8,10,12,14….
例如：FreqOffsetIndicator＝1；InterDis＝2；系统中可用于SA传输的PRB为：1,3,5,7….
403、该UE在可用频域资源上进行检测。
此时，由于已经大大缩小了SA信息所在PRB的频域范围，因此，在进行盲检测的时候，UE可以仅在已确定的可用频域资源位置上进行检测，大大降低了检测范围和检测次数，从而能够降低检测的复杂度以及设备功耗。
404、当检测到SA信息时，UE接收业务数据信息。
UE在接收到SA信息后，可以通过SA信息所指示的时频资源位置，接收来自发送端的业务数据。
而在SA资源和业务数据资源在频域上连续的场景下，UE还可以直接根据SA信息所在时频资源，确定业务数据所在时频资源，因此，通过这种资源表示方式，可以只需要配置SA或者数据资源池即可，无需配置两个资源池。
本发明实施例提供的方法，在SA资源池的配置信息中增加两个频域资源指示参数，可以有效的指示SA资源池的频域资源，大大降低了检测范围和检测次数，从而能够降低检测的复杂度以及设备功耗。且由于配置信息采用了连续两个SA资源的频域间隔这种表示方式，也允许基站对SA资源的大小进行灵活的配置，大大提高了资源利用率。
上述图4所示实施例仅以SA资源池为例进行了说明，而事实上对于D2D数据中的业务数据资源池，也可以采用同理的方式进行配置，在业务数据资源池的配置信息中增加两个频域资源指示参数，可以有效的指示业务数据资源池的频域资源，大大降低了检测范围和检测次数，从而能够降低检测的复杂度以 及设备功耗。
上述实施例均是以用户设备作为接收端的场景进行说明，而事实上，用户设备还可以作为发送端进行D2D数据的发送，具体地，参见如图5所示的D2D通信过程：
500、基站向UE发送资源池配置信息，该资源池配置信息包括频域资源位置信息和时域资源位置信息，该频域资源位置信息包括该频域资源的起始位置和结束位置和连续两个SA资源的频域间隔。
本发明实施例仅以该资源池配置信息中的SA资源池配置信息为例进行说明，而事实上，该基站所发送的资源池配置信息可以包括SA资源池配置信息和业务数据资源池配置信息，当然，在SA资源和业务数据资源为频域上连续的情况下，还可以仅携带SA资源池配置信息或业务数据资源池配置信息，则可以由其中一个推算出另一个的频域位置，以提高配置信息利用率。
501、UE接收该资源池配置信息。
502、UE根据该资源池配置信息，确定可用频域资源。
该UE可以根据该频域资源的起始位置和结束位置，确定该可用频域资源所在频域范围，再根据可用频域资源所在频域范围和连续两个SA资源的频域间隔，确定可用频域资源位置。
例如，当频域资源的起始位置为10，结束位置为60时，则可以确定频域资源所在频域范围的PRB为10至60。如果连续两个SA资源的频域间隔为4，且单位为PRB时，则可以确定可用频域资源位置，也即是可用于SA传输的PRB为：10,14,18,22…以此类推。
503、UE在可用频域资源中，选取任一可用频域资源，在所选取的时频资源位置上发送SA信息。
UE在选取资源池的传输资源时，可以根据资源池配置信息从该可用频域资源中进行选取，可以提高选取效率，并通过配置信息中所指示业务数据资源 池的频域资源，使得接收端在接收过程中可以大大降低了检测范围和检测次数，从而能够降低检测的复杂度以及设备功耗。
图6是本发明实施例提供的一种用户设备的结构示意图。参见图6，该用户设备包括：
收发单元601，用于接收资源池配置信息，所述资源池配置信息包括频域资源位置信息和时域资源位置信息，所述频域资源位置信息包括频域资源池指示和连续两个设备到设备D2D资源的频域间隔，所述频域资源池指示用于指示可用频域资源所在频域范围；
确定单元602，用于根据所述资源池配置信息，确定可用频域资源；
所述收发单元601，还用于在所述可用频域资源上进行D2D通信。
