技术领域

背景技术
在版本12(Rel-12)定义的D2D通信中，有如下的设计：
D2D通信采用SC-FDM的方式传输，并且在一个子帧中不允许同时进行传输蜂窝的上行和D2D的传输；
由于双工间隔的影响，在同一个载波上接收的同时不能发送，并且发送的同时也不能接收。
在LTE-Advanced(3GPP R13)版本13(Rel-13)的设备到设备(Device to Device，D2D)通信增强中，提出了需要支持用户设备到网络(UE-to-network)中继的通信方式，具体如图1所示。其中中继(Relay)节点也是一个支持D2D通信的用户设备(User Equipment，UE)。
由于上述Rel-12中对D2D通信的设计，结合UE-to-network中继的过程中，中继(Relay)UE的中继发送与覆盖外UE(Remote UE)的D2D链路发送之间可能存在资源冲突。这里，如图1所示，该覆盖外用户设备是指网络侧设备(例如，eNB)覆盖范围之外的用户设备。

在对本公开文本实施例提供的技术方案进行详细说明之前，首先对本公开文本实施例涉及到的资源池进行说明。
Relay UE的D2D link发送资源池(或资源)，又可写作Relay UE D2D link Tx资源池(或资源)，表示Relay UE用于UE-to-network中继的D2D Tx资源池(或资源)，即Relay UE用于UE-to-network中继的D2D link的发送的资源池(或资源)。
Remote UE的D2D link发送资源池(或资源)，又可写作Remote UE D2D link Tx资源池(或资源)。即Relay UE D2D link Rx资源池(或资源)，表示Remote UE用于UE-to-network中继的D2D Tx资源池(或资源)，即Remote UE用于UE-to-network中继的D2D link的发送的资源池(或资源)，也即Relay UE用于UE-to-network中继的D2D link的接收的资源池(或资源)。
预配置的覆盖外UE的D2D资源池，包括覆盖外UE的D2D发现资源池(又分为接收资源池和发送资源池)，和覆盖外UE的D2D通信资源池(又分为接收资源池和发送资源池)。
中继发送资源，用于Relay UE的UE-to-network中继的发送，可以是指Relay UE用于UE-to-network中继的蜂窝上行资源，也可以是指Relay UE用于UE-to-network中继的D2D link发送资源(或资源池)。
下面将结合附图，对本公开文本实施例提供的技术方案进行详细说明。
本公开文本实施例提供的基站侧的资源协调的方法如图2所示，具体包括如下操作：
步骤100、获取Remote UE的D2D链路发送资源池的时域资源的信息。
如果以子帧表示时域，则时域资源的信息具体可以通过子帧信息体现。
步骤110、根据获取的Remote UE的D2D链路发送资源池的时域资源的信息，为Remote UE对应的Relay UE确定中继发送资源。这里，该Remote UE(覆盖外用户设备)是指基站(例如，eNB)覆盖范围之外的用户设备。
本公开文本实施例中，在获取了Remote UE的D2D链路发送资源池的时域资源的信息之后，只要Remote UE的D2D链路发送资源池不发生变化，每当为该Relay UE确定中继发送资源时，均根据本次获取的Remote UE的D2D链路发送资源池的时域资源的信息确定。
当然，也可以在每次为该Relay UE确定中继发送资源时，均获取Remote UE的D2D链路发送资源池的时域资源的信息。
本公开文本实施例提供的技术方案，基站能够提前获取Remote UE的D2D链路发送资源池的时域资源的信息，就能够根据Remote UE的D2D链路发送资源池的时域资源的信息为Relay UE确定中继发送资源，从而降低甚至避免Relay UE的中继发送与其用于UE-to-network中继的D2D link的接收之间的资源冲突，有效提高了UE-to-network中继的效率和可靠性。
在如图3所示的场景中，Relay UE的用于UE-to-network中继的蜂窝上行(cellular UL)发送(包括物理上行共享信道(PUSCH)的传输，以及正确确认/错误确认(ACK/NACK)反馈的传输)与Relay UE的用于UE-to-network中继的D2D链路(D2D link)的接收发生在同一子帧。这时候由于双工间隔的原因，Relay UE不能在进行蜂窝发送(Cellular Tx)的情况下同时进行D2D link的接收。
基于图3所示的场景，为了降低甚至避免Relay UE的蜂窝上行传输与其D2D link的接收之间的资源冲突，本公开文本实施例提出的一种解决方案。
基站侧的解决方案一：
上述步骤110的实现方式可以是：当需要为Relay UE调度蜂窝上行资源时，根据获取的Remote UE的D2D链路发送资源池的时域资源的信息，为该Relay UE调度蜂窝上行资源。
上述实施例中，为该Relay UE调度蜂窝上行资源的具体实现方式有多种，任何旨在降低或避免Relay UE的蜂窝上行发送与其D2D link的接收之间的资源冲突的调度方式均适用于本公开文本。例如，为Relay UE调度的蜂窝上行资源与Remote UE的D2D链路发送资源池在时域上不重叠(错开)。也可以结合上述时域资源的信息与其他信息，为Relay UE调度蜂窝上行资源。例如，分别为Relay UE用于UE-to-network中继的蜂窝上行传输、Relay UE用于 UE-to-network中继的D2D链路发送和Relay UE用于UE-to-network中继的D2D链路接收设置优先级。如果蜂窝上行传输的优先级最高，也可以为Relay UE调度在时域上与Relay UE用于UE-to-network中继的D2D接收有重叠的资源，否则根据上述获取的时域资源的信息，尽量与Relay UE用于UE-to-network中继的D2D链路接收的资源不重叠。
在如图4所示的场景中，在Relay UE的D2D link的发送与Relay UE的D2D link的接收发生在同一个子帧，那么由于双工的原因，也存在资源冲突，导致Remote UE和Relay UE之间无法互相接收。
为了降低甚至避免Relay UE的D2D link的发送与Relay UE的D2D link的接收之间的资源冲突，本公开文本实施例提出如下两种解决方案。
基站侧的解决方案二：
上述步骤110的实现方式为：当需要为Relay UE调度D2D链路发送资源时，根据获取的Remote UE的D2D链路发送资源池的时域资源的信息，为Relay UE调度D2D链路发送资源。
其中，为Relay UE调度D2D链路发送资源的具体实现方式有多种，凡是旨在降低或避免Relay UE的D2D link的发送和接收之间的资源冲突的调度方式，均适用于本公开文本。优选的，为Relay UE调度的中继发送资源与Remote UE的中继发送资源池在时域上不重叠。又例如，分别为Relay UE用于UE-to-network中继的蜂窝上行传输、Relay UE用于UE-to-network中继的D2D链路发送和Relay UE用于UE-to-network中继的D2D链路接收设置优先级。如果Relay UE用于UE-to-network中继的D2D发送的优先级最高，也可以为Relay UE调度在时域上与Relay UE用于UE-to-network中继的D2D接收有重叠的资源。
本实施例提供的解决方案，基站能够提前获取Remote UE的D2D链路发送资源池的时域资源的信息，就能够根据Remote UE的D2D链路发送资源池的时域资源为Relay UE调度D2D链路发送资源，从而降低甚至避免Relay UE的D2D链路发送与其D2D link的接收之间的资源冲突。
基站侧的解决方案三：
上述步骤110的实现方式为，根据获取的Remote UE的D2D链路发送资 源池的时域资源的信息，为Relay UE配置D2D链路发送资源池，并向Relay UE通知其D2D链路发送资源池的配置。
为Relay UE配置D2D链路发送资源池的实现方式有多种，凡是旨在降低或避免Relay UE的D2D link的发送和接收之间的资源冲突的配置方式，均适用于本公开文本。
例如，为Relay UE配置的D2D链路发送资源池与Remote UE的D2D链路发送资源池在时域上完全不重叠(又称在时域上正交)。这种情况下，Relay UE选择D2D链路发送资源池中的任何资源进行D2D link的发送时，均能够完全避开其D2D link的接收，从而避免了资源冲突。
又例如，为Relay UE配置的D2D链路发送资源池与Remote UE的D2D链路发送资源池在时域上不完全重叠。这种情况下，优选的，Relay UE也需要获知Remote UE的D2D链路发送资源池的时域资源，才能在选择D2D链路发送资源时，降低或避免与D2D link的接收的资源冲突。
本实施例提供的解决方案，基站能够提前获取Remote UE的D2D链路发送资源池的时域资源的信息，就能够根据Remote UE的D2D链路发送资源池的时域资源的信息为Relay UE配置D2D链路发送资源池，从而降低甚至避免Relay UE的D2D链路发送与其D2D link的接收之间的资源冲突。
基于上述任意基站侧实施例，其中，获取Remote UE的D2D链路发送资源池的时域资源的信息的实现方式有多种。下面例举其中几种：
实现方式一、通过预定义的方式获取该Remote UE的D2D链路发送资源池的时域资源的信息。
这种实现方式，基站及Remote UE对Remote UE的D2D链路发送资源池的时域资源的信息的预定义的理解一致。也就是说，基站和Remote UE根据该预定义确定出的Remote UE的D2D链路发送资源池的时域资源一致。
具体实现中，基站可以根据对Remote UE的D2D链路发送资源池的预定义，确定出Remote UE的D2D链路发送资源池的完整配置或时频资源配置等等，进而获知其时域资源的信息。
本公开文本实施例中，不对上述预定义的具体实现方式进行限定。可选的，通过预定义，将预配置的覆盖外UE的至少一个D2D communication资 源池和/或至少一个D2D discovery资源池配置为Remote UE的D2D链路发送资源池。
实现方式二、通过Relay UE上报的方式获取Remote UE的D2D链路发送资源池的时域资源的信息。
具体实现中，Relay UE可以上报Remote UE的D2D链路发送资源池的完整配置，或者Remote UE的D2D链路发送资源池的时频资源等等。相应的，基站从中获取时域资源的信息。
实现方式三、为Remote UE配置D2D链路发送资源池，该D2D链路发送资源池至少包括时域资源。
相应的，还通过Relay UE向Remote UE通知为其配置的D2D链路发送资源池。
由于基站为Remote UE配置D2D链路发送资源池，因此基站肯定也就获取了Remote UE的D2D链路发送资源池的时域资源的信息。
在该实现方式三中，基站可以单独为一个Remote UE配置D2D链路发送资源池，也可以为一组Remote UE配置D2D链路发送资源池。
其中，实现方式三至少包括三种具体实现方式：
实现方式三A、将预配置的覆盖外UE的至少一个D2D communication资源池和/或至少一个D2D discovery资源池配置为Remote UE的D2D链路发送资源池。相应的，通过Relay UE向Remote UE通知的是预配置的覆盖外UE的D2D communication资源池和/或D2D discovery资源池的标识信息。当然，也可以将具体配置信息通知给Remote UE。
实现方式三B、基站为Remote UE配置完整的D2D链路发送资源池，相应的，通过Relay UE将Remote UE的D2D链路发送资源池的完整配置信息发送给Remote UE。
实现方式三C、基站为Remote UE配置D2D链路发送资源池的部分参数(至少配置时域资源)，相应的，通过Relay UE将Remote UE的D2D链路发送资源池的部分配置参数发送给Remote UE。
相应的，本公开文本实施例提供的Relay UE侧的资源协调的方法如图5所示，具体包括如下操作：
步骤200、获取中继发送资源，该中继发送资源是根据Remote UE的中继发送资源池的时域资源的信息确定的。
步骤210、通过上述中继发送资源进行中继发送。
本公开文本实施例提供的技术方案，由于Relay UE的中继发送资源是根据Remote UE的D2D链路发送资源池的时域资源的信息确定的，因此，Relay UE在进行中继发送时，能够降低甚至避免与其D2D link的接收之间的资源冲突，有效提高了UE-to-network中继的效率和可靠性。
对应于上述基站侧的解决方案一，Relay UE侧的解决方案如下：
上述步骤200的具体实现方式可以是：获取基站调度的蜂窝上行资源。
步骤210的具体实现方式可以是：在所述基站调度的蜂窝上行资源上进行蜂窝上行传输。
对应于上述基站侧的解决方案二，Relay UE侧的解决方案如下：
上述步骤200的实现方式为：获取基站调度的D2D链路发送资源；
在基站调度的D2D链路发送资源上进行D2D链路发送。
对应于上述基站侧的解决方案三，或者对应于基站侧不根据Remote UE的D2D链路发送资源池的时域资源为Relay UE配置中继发送资源池的情况，Relay UE侧的解决方案如下：
步骤200的实现方式为：根据获取的Remote UE的D2D链路发送资源池的时域资源的信息，从基站为自身配置的D2D链路发送资源池中选择资源；
步骤210的实现方式为：在选择的资源上进行D2D链路发送。
其中，Relay UE选择资源以进行D2D链路发送的实现方式有多种。凡是旨在降低甚至避免Relay UE的D2D link的发送和接收之间的资源冲突的资源选择方式，均适用于本公开文本。例如，Relay UE选择的资源在时域上与Remote UE的D2D链路发送资源不重叠。具体的，Relay UE可以从自身的、与Remote UE的D2D链路发送资源池在时域上不重叠的D2D链路发送资源池中选择资源；也可以从自身的、与Remote UE的D2D链路发送资源池在时域上部分重叠的D2D链路发送资源池中，选择合适的传输子帧和静默子帧，从而避免与Relay UE的D2D link的接收发生资源冲突。如果设置了Relay UE用于UE-to-network中继的蜂窝上行传输、Relay UE用于UE-to-network中继 的D2D链路发送和Relay UE用于UE-to-network中继的D2D链路接收设置优先级，且Relay UE用于UE-to-network中继的D2D链路发送的优先级最高，那么，Relay UE可以选择用于UE-to-network中继的D2D链路接收的子帧作为传输子帧。
本实施例的方案中，Relay UE能够提前获取Remote UE的D2D链路发送资源池的时域资源的信息，从而可以根据Remote UE的D2D链路发送资源池的时域资源的信息选择用于D2D链路发送的资源，降低甚至避免Relay UE的D2D link的发送和接收之间的资源冲突。
基于上述任意Relay UE实施例，Relay UE获知Remote UE的D2D链路发送资源池的时域资源的实现方式有多种，下面例举其中几种：
实现方式一、为Remote UE确定D2D链路发送资源池。
其中，确定的Remote UE的D2D链路发送资源池至少包括时域资源的信息。
进一步的，还向Remote UE通知为其确定的D2D链路发送资源池，且还向基站上报Remote UE的D2D链路发送资源池的时域资源。
其中，Relay UE可以是从预配置的覆盖外UE的发送资源池中选择至少一个，确定为Remote UE的D2D链路发送资源池；也可以根据自身的信息，例如基站配置的Relay UE的D2D链路发送资源池，以及Relay UE监听到的其它测量的结果，确定Remote UE的D2D链路发送资源池；也可以参照基站侧配置D2D链路发送资源池的实施例为Remote UE确定D2D链路发送资源池。
具体实现中，上述确定过程可以但不仅限于在Relay Discovery过程实现。
假如Relay UE和Remote UE之间通过模式A(Mode A)实现Relay Discovery。相应的，Relay UE确定Remote UE的D2D链路发送资源池，并在发送的Announcement消息中携带Remote UE的D2D链路发送资源池的配置信息。
假如Relay UE和Remote UE之间通过模式B(Mode B)实现Relay Discovery。相应的，Relay UE接收到Remote UE的请求(Request)消息后，向Remote UE返回响应(Response)消息，并在响应消息中携带为Remote UE 确定的D2D链路发送资源池的配置信息。其中，Relay UE既可以在接收到请求消息之前，就确定Remote UE的D2D链路发送资源(不针对具体的某个Remote UE)，也可以在接收到请求消息之后，为发送请求消息的Remote UE确定D2D链路发送资源(既可以针对该Remote UE为其进行确定，也可以为所有的Remote UE确定相同的D2D链路发送资源)。
实现方式二、获取基站发送的为Remote UE配置的D2D链路发送资源池的通知，根据该通知获取Remote UE的D2D链路发送资源池的时域资源的信息。
获取上述通知之后，进一步的，还将该通知转发给Remote UE。
如果基站需要为不同的Relay UE配置不同的Remote UE的D2D链路发送资源池(也就是Relay UE的D2D链路接收资源池)，则Relay UE还向Remote UE通知Relay UE的标识信息。
实现方式三、通过预定义的方式获取Remote UE的D2D链路发送资源池的时域资源的信息。
这种实现方式，Relay UE及Remote UE对Remote UE的D2D链路发送资源池的时域资源的信息的预定义的理解一致。也就是说，Relay UE和Remote UE根据该预定义确定出的Remote UE的D2D链路发送资源池的时域资源的信息一致。
如果基站也通过预定义的方式获知Remote UE的D2D链路发送资源池的时域资源的信息，那么，基站、Relay UE和Remote UE三者之间对上述预定义的理解一致。
如果基站无法通过预定义的方式获知Remote UE的D2D链路发送资源池的时域资源的信息，那么，在Relay UE在通过预定义的方式获取Remote UE的D2D链路发送资源池的时域资源的信息之后，可以将Remote UE的D2D链路发送资源池的时域资源的信息上报给基站。
基于与方法同样的发明构思，本公开文本实施例还提供一种资源协调的装置，如图6所示，所述装置被设置在基站处并且包括：
