Description

D2D资源的配置、分配方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种设备到设备(Device-to-Device，简称为D2D)资源的配置、分配方法及装置。
背景技术
随着无线多媒体业务的发展，人们对高数据速率和用户体验的需求日益增长，从而对传统蜂窝网络的系统容量和覆盖提出了较高要求。另一方面公共安全、社交网络、近距离数据共享、本地广告等应用场景使得人们对了解附近人或事物并与之通信(Proximity Services，邻近服务)的需求逐渐增加。传统的以基站为中心的蜂窝网络在高数据速率以及邻近服务的支持方面存在明显的局限性，在这种需求背景下，代表未来通信技术发展新方向的D2D技术应运而生。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足上述高数据速率业务和邻近服务的要求。
D2D技术可以工作在授权频段或非授权频段，允许多个支持D2D功能的用户设备(即D2D用户设备，D2D User Equipment，D2D UE)在有网络基础设施或无网络基础设施的情况下进行直接发现/直接通信。D2D的应用场景主要有三种：
1)UE1和UE2在蜂窝网络的覆盖下进行数据交互，用户面数据不经过网络基础设施，如图1的模式1。
2)在弱/无覆盖区域的UE中继传输，如图1中的模式2，允许信号质量较差的UE4通过附近有网络覆盖的UE3与网络进行通信，能帮助运营商扩展覆盖、提高容量。
3)在发生地震或紧急情况，蜂窝网络不能正常工作的情况下，允许设备间直接通信，如图1中的模式3，UE5，UE6和UE7间控制面和用户面都不经过网络基础设施而进行一跳或多跳的数据通信。
D2D技术通常包括D2D发现技术和D2D通信技术，其中，D2D发现技术是指用于判断/确定UE之间是否邻近的技术。通常，D2DUE间可通过发送或接收发现信号/信息来发现对方。D2D通信技术是指D2DUE之间部分或全部通信数据可以不通过网络基础设施而直接进行通信的技术。
根据现有3GPP标准会议的进展，无论是D2D发现还是D2D通信资源，都存在两种资源分配方式，即基于竞争的资源获取(第一资源分配方式)或是由基站为UE分配专有的资源(第二资源分配方式)进行D2D发现/通信。第一资源分配方式通常由基站或是系统预分配一个D2D资源池，参与D2D发现/通信的D2DUE监听该资源池，并通过竞争的方式获取D2D发送资源。而第二资源分配方式由基站根据UE的请求为UE分配合适的D2D资源。
相关技术并未对具体D2DUE的D2D资源配置方法给出系统完善的解决方案。

实施例一
本实施例给出D2D发现资源的配置建立，更新及释放过程。以下通过实例1至实例3详细阐述。
实例1
在商业应用场景，Mary和John持有具备D2D发现功能的UE1和UE2。UE1和UE2彼此在D2D发现范围内。UE1想要进行D2D发现，因此发送D2D资源配置请求消息给eNB。D2D资源配置请求消息中可包含D2D发现指示，D2D UE的优先级，D2D UE的能力，周期性/一次性指示，持续时间等，如图6所示。
eNB根据保存的UE1的上下文信息，对UE1进行认证。假设D2D UE1无法通过认证，则eNB发送D2D配置失败消息给UE，其中拒绝原因为认证未通过。如果通过认证，且认证指示或D2D UE的能力指示或当前Type过载使得UE1仅能使用Type1 资源，则eNB发送D2D资源配置消息给UE1，其中包含Type1发送资源池信息。D2D资源配置消息还可包含Type1接收资源池信息以及Type2接收资源池信息。可选的，D2D资源配置信息可以有一个有效期。除此之外，还可以包含D2D UE1的QoS信息，如priority，MBR等，这里信息可以由eNB从MME获取到UE context中获取，可选的，这些信息也可以从NAS信令获取。
如果Type1资源池有多个，如根据不同的应用类型，不同的D2D UE优先级以及D2D UE的状态划分了不同的Type1资源池，则eNB可根据D2D资源请求，仅发送特定的资源池，如对应于特定应用的资源池。或者eNB为UE同时配置多个Type1资源池，分别对应于不同的发送状态，如连接态使用一个Type1资源池，idle态使用另一个type1资源池。此外，eNB还可将邻区的Type1和或Type2接收资源池信息发送给UE。
UE1获取D2D资源配置之后，向eNB发送D2D资源配置确认消息，之后根据接收到的Type1发送资源池信息基于竞争的方式从Type1资源池中获取资源进行D2D发送。D2D UE1获取到的QoS信息可以影响D2D UE1资源竞争操作，如不同的QCI可以对应不同的backoff时长以及carrier sensing时长，此外D2D UE1可以监控自己单位时间内获取到的资源，保证不超过MBR。此外UE1可根据D2D资源配置信息中包含的本小区以及邻区的Type1接收资源池和或Type2接收资源池信息进行D2D发现消息的监听。
D2D UE1可以将已访问小区以及获取到的邻区的Type1和或Type2资源池信息以及UE的QoS信息保存下来，用于下次接入该小区或是邻近该小区时执行D2D发现。可选的，UE1进入idle态之后，这种资源池配置信息可以有一个有效期，如果超出了该有效期，则D2D UE1将该信息删除。
实例2
在商业应用场景，Mary和John持有具备D2D发现功能的UE1和UE2。UE1和UE2彼此在D2D发现范围内。eNB在SIB广播消息中发送支持D2D的指示，处于空闲态的UE1获取到该信息后想要进行D2D发现，因此首先进入连接态，发送D2D资源配置请求消息给eNB。D2D资源配置请求消息中可包含D2D发现指示，D2D UE的能力，D2D UE的应用类型，D2D UE的优先级，周期性/一次性指示，持续时间等，如图7所示。
eNB接收到D2D资源配置请求消息后，对D2D UE进行授权认证以及接纳控制。如果有足够的Type2资源，则eNB根据D2D UE的应用类型以及周期性/一次性指示 以及持续时间为D2D UE分配资源。如果资源不够，则eNB进一步根据D2D UE的优先级判断是否可以抢占其他UE的D2D资源(这里的抢占资源对应的优先级也可以由eNB从MME接收到的UE context中获取，类似的，进一步的，可以从MME获取D2D对应的QoS信息，如QCI，ARP，MBR等)。如果UE可以抢占其他UE的资源，则eNB向被抢占资源的UE发送D2D资源重配消息(要求UE释放其type2B资源)，等收到被强占资源回复的确认消息后，向请求资源的D2D UE发送资源重配消息，其中包含具体的Type2发送资源时频域位置，周期，时长等。如果D2D UE的优先级不足以抢占其他UE的资源，则eNB向D2DUE发送D2D资源配置/重配消息，其中仅包含type1的发送资源信息，如果eNB没有配置type1的资源，则eNB向UE发送资源配置拒绝消息，原因指示资源不足，如图8所示。可选的，资源配置拒绝消息中可以携带一个禁止定时器，要求UE在禁止定时器超时之前不要重复发送D2D资源配置请求消息。
实例3
如果出现下面情况，则会触发D2D资源的重配流程，进行D2D资源配置的释放或更新：eNB收到UE发送的资源释放请求，则eNB对资源进行重配(释放)；Type2资源池发生变化时，eNB对涉及到的D2D UE所使用的资源进行重配(释放/更新)；低优先级的D2D UE的type2资源被抢占时，eNB向低优先级的D2D UE发送D2D资源重配(释放)消息，使其释放type2资源，如果可能的话转而使用type1资源；D2DUE的能力/授权信息发生变化，则eNB对D2D UE所使用的资源进行重配。具体流程如图9所示。
实施例二
本实施例给出D2D通信资源的配置建立，更新及释放过程。以下通过实例4至实例10详细阐述。
实例4
在公共安全场景，Officer A，B，C，D使用具备D2D功能的公共安全UE1，UE2，UE3及UE4。Officer A，B，C，D都订阅了公共安全服务，并且UE1，UE2，UE3都配置属于D2D通信组X。在Officer A，B，C，D到达救援地点之后，他们的UE都不在网络覆盖范围内，但是UE1，UE2，UE3，UE4彼此在D2D通信范围内。
在救援地点，Officer A希望发起组播通话，告知附近对应于D2D通信组X的其他Officer相关信息。Officer A的UE1发送D2D资源配置请求消息给eNB。D2D配置 请求消息中可包含D2D通信指示，优先级，组标识，业务类型，周期性/一次性指示/持续时间等信息，如图10所示。D2D资源配置请求信息可通过独立的D2D资源配置请求承载，也可以在RRCConnectionRequest/RRCConnectionSetupComplete消息中携带，简单的，此时只要在RRCConnectionRequest/RRCConnectionSetupComplete携带一个D2D通信指示即可。
eNB根据保存的UE1的上下文信息，对UE1进行认证。假设D2D UE1无法通过认证，则eNB发送D2D资源配置拒绝消息给UE1，其中拒绝原因为认证未通过。如果通过认证，则eNB进一步判断Mode1资源使用情况，如果有足够的资源，则eNB根据D2D UE1的业务类型以及周期性/一次性指示考虑为D2D UE1分配资源。如果资源不够，则eNB进一步根据D2D UE1的优先级判断是否可以抢占其他UE的D2D资源(这里的抢占资源对应的优先级也可以由eNB从MME获取到UE context中获取，类似的，进一步的，可以从MME获取D2D对应的QoS信息，如ARP，MBR等)。如果UE1可以抢占其他UE的资源，则eNB向被抢占资源的UE发送D2D资源重配(释放/修改)消息。等收到被强占资源回复的确认消息后，向请求资源的D2D UE1发送资源配置消息，其中包含Mode1以及Mode2的发送资源配置建立。如果D2D UE1的优先级不足以抢占其他UE的资源，则eNB向D2D UE1发送仅包含Mode2发送资源配置建立的消息。如果eNB不支持Mode2资源池，则eNB向UE1发送D2D资源请求拒绝消息，原因指示资源不足。可选的，资源请求拒绝消息中可以携带一个禁止定时器，要求UE1在禁止定时器超时之前不要重复发送D2D资源配置请求消息。D2D资源配置消息还可以包含本小区以及邻区Mode1以及Mode2的接收资源池信息，也可以包含Mode1的D2D RNTI，用于后续D2D资源分配，该消息可以是独立的D2D资源配置/重配RRC信令，也可以通过RRCConnectionSetup/RRCConnectionReconfiguration/RRCConnection reestablishment消息承载。此外，eNB还可考虑将用户面配置信息通过D2D资源配置消息发送给D2D UE1。
D2D UE1接收到包含D2D资源配置的消息后，检测到同时包含Mode1和Mode2发送资源配置信息，则D2D UE1向eNB发送BSR，上报D2D承载的buffer状态。eNB根据接收到的BSR判断为D2D UE分配半持续资源还是动态资源。如果是半持续资源，则eNB进一步向D2D UE1下发SPS配置，其中包含D2D-SPS-RNTI，SPS周期，子帧偏移等信息，等到D2D UE1完成SPS配置后，eNB可对SPS资源进行激活。UE1根据接收到的D2D-SPS-RNTI加扰的D2D grant之后，使用相应的资源进行D2D SA的传输以及数据传输。D2D UE1可根据需要主动要求释放SPS资源，或是由eNB发送SPS去激活命令给UE1，此后D2D UE1停止D2D SPS传输。此外D2D UE1还可 根据接收到的Mode1和或Mode2接收资源配置建立信息，对相邻其他UE的D2D发送进行监听并接收数据。
D2D UE1可以将从基站收到的D2D配置信息保存下来，用于下次接入该小区或是邻近该小区时执行D2D发现。可选的，这种资源池配置信息可以有一个有效期，如果超出了该有效期，则D2D UE1将该信息删除。
实例5
在公共安全场景，Officer A，B，C，D使用具备D2D功能的公共安全UE1，UE2，UE3及UE4。Officer A，B，C，D都订阅了公共安全服务，并且UE1，UE2，UE3都配置属于D2D通信组X。在Officer A，B，C，D到达救援地点之后，他们的UE都不在网络覆盖范围内，但是UE1，UE2，UE3，UE4彼此在D2D通信范围内。
在救援地点，Officer A希望发起组播通话，告知附近对应于D2D通信组X的其他Officer相关信息。Officer A的UE1发送D2D资源配置请求消息给eNB。D2D配置请求消息中可包含D2D通信指示，优先级，组标识，业务类型，周期性/一次性指示/持续时间等信息，如图11所示。D2D资源配置请求信息可通过独立的D2D资源配置请求承载，也可以在RRCConnectionRequest/RRCConnectionSetupComplete消息中携带，简单的，此时只要在RRCConnectionRequest/RRCConnectionSetupComplete携带一个D2D通信指示即可。
eNB根据保存的UE1的上下文信息，对UE1进行认证。假设D2D U1E无法通过认证，则eNB发送D2D资源配置拒绝消息给UE，其中拒绝原因为认证未通过。如果通过认证，则eNB进一步判断Mode1资源使用情况，如果有足够的资源，则eNB根据D2D UE1的业务类型以及周期性/一次性指示考虑为D2D U1E分配资源。如果资源不够，则eNB进一步根据D2D UE1的优先级判断是否可以抢占其他UE的D2D资源(这里的抢占资源对应的优先级也可以由eNB从MME获取到UE context中获取，类似的，进一步的，可以从MME获取D2D对应的QoS信息，如ARP，MBR等)。如果UE1可以抢占其他UE的资源，则eNB向被抢占资源的UE发送D2D资源重配(释放/修改)消息。等收到被强占资源回复的确认消息后，向请求资源的D2D UE1发送资源配置消息，其中包含Mode1以及Mode2的发送资源配置建立。如果D2D UE1的优先级不足以抢占其他UE的资源，则eNB向D2D UE1发送仅包含Mode2发送资源配置建立的消息。如果eNB不支持Mode2资源池，则eNB向UE1发送D2D资源请求拒绝消息，原因指示资源不足。可选的，资源请求拒绝消息中可以携带一个禁止定时器，要求UE1在禁止定时器超时之前不要重复发送D2D资源配置请求消息。D2D 资源配置消息还可以包含本小区以及邻区Mode1以及Mode2的接收资源池信息，也可以包含Mode1的D2D RNTI，用于后续D2D资源分配，该消息可以是独立的D2D资源配置/重配RRC信令，也可以通过RRCConnectionSetup/RRCConnectionReconfiguration/RRCConnection reestablishment消息承载。
此外，eNB还可考虑将用户面配置信息通过D2D资源配置消息发送给D2D UE1。D2D UE接收到包含D2D资源配置的消息后，检测到同时包含Mode1和Mode2发送资源配置信息，则D2D UE向eNB发送BSR，上报D2D承载的buffer状态。eNB根据接收到的BSR判断为D2D UE分配半持续资源还是动态资源。如果eNB确定给D2DUE1动态分配资源，则只需直接将D2D-RNTI加扰的D2D grant发给UE1即可。
D2D UE1可以将从基站收到的D2D配置信息保存下来，用于下次接入该小区或是邻近该小区时执行D2D发现。可选的，这种资源池配置信息可以有一个有效期，如果超出了该有效期，则D2D UE1将该信息删除。
实例6
除了实例4和实例5描述的D2D资源配置与资源请求独立完成的场景，也可以考虑D2D资源请求与配置联合的信令流程，如图12所示。eNB可根据D2D UE1发送的针对D2D的SR/BSR对UE的D2D通信能力进行授权验证，如果通过验证，并且Mode1资源充足，则向UE发送包含Mode1以及Mode2发送资源的配置/重配消息。其中Mode1的配置可包含SPS和或动态配置，如果是SPS配置，则包含D2D-SPS-RNTI，SPS周期以及子帧偏移等，如果是动态配置，则包含D2D-RNTI。此外配置/重配消息还包含本小区以及邻区的Mode1和或Mode2接收资源池信息。
D2D UE1收到D2D资源配置/重配消息，并进行相应的配置，之后向eNB发送资源配置/重配确认消息。eNB收到该确认消息后，如果确定触发SPS配置，则eNB对SPS资源进行激活，此后D2D UE1可以使用对应的SPS资源进行D2D发送。
实例7
在公共安全场景，Officer A，B，C，D使用具备D2D功能的公共安全UE1，UE2，UE3及UE4。Officer A，B，C，D都订阅了公共安全服务，并且UE1，UE2，UE3都配置属于D2D通信组X。在Officer A，B，C，D到达救援地点之后，他们的UE都不在网络覆盖范围内，但是UE1，UE2，UE3，UE4彼此在D2D通信范围内。
在救援地点，Officer A希望发起组播通话，告知附近对应于D2D通信组X的其他Officer相关信息。Officer A的UE1希望发起D2D通信，则UE1发送D2D的SR/BSR，如图13所示。基站接收到后，可根据D2D UE发送的针对D2D的SR/BSR对UE的D2D通信能力进行授权验证。假设D2D UE1无法通过认证，则eNB发送D2D资源配置拒绝消息给UE1，其中拒绝原因为认证未通过。如果通过认证，则eNB进一步判断Mode1资源使用情况，如果没有足够的Mode1资源且如果D2D UE1的优先级不足以抢占其他UE的资源，则eNB向D2D UE发送仅包含Mode2发送资源配置的消息。D2D UE接收到仅包含Mode2资源配置的消息后，根据接收到的D2D mode2发送资源池信息进行D2D传输。此外D2D UE1还可根据接收到的Mode1和或Mode2接收资源配置建立信息，对相邻其他UE的D2D发送进行监听并接收数据。
实例8
在商业应用场景，Mary和John持有具备D2D通信功能的UE1和UE2。UE1和UE2彼此在D2D通信范围内。
UE1希望发起与UE2的D2D通信，则UE1发送D2D资源配置请求消息给eNB，如图14所示。D2D配置请求消息中可包含D2D通信指示，优先级，组标识，业务类型，周期性/一次性指示/持续时间等信息，D2D资源配置请求信息可通过独立的RRC信令携带如专门的D2D资源配置/重配请求消息，也可以在RRCConnectionSetupRequest消息中携带。
eNB根据保存的UE的上下文信息，对UE1进行认证。假设D2D UE1无法通过认证，则eNB发送D2D资源配置拒绝消息给UE1，其中拒绝原因为认证未通过。如果通过认证，则eNB进一步判断Mode1资源使用情况，如果没有足够的Mode1资源且如果D2D UE1的优先级不足以抢占其他UE的资源，则eNB向D2D UE发送仅包含Mode2发送资源配置的消息。D2D UE接收到仅包含Mode2资源配置的消息后，根据接收到的D2D mode2发送资源池信息进行D2D传输。此外D2D UE1还可根据接收到的Mode1和或Mode2接收资源配置建立信息，对相邻其他UE的D2D发送进行监听并接收数据。
实例9
如果出现下面情况，则会触发D2D资源的重配流程，进行D2D资源配置的释放或更新：eNB收到UE发送的资源释放请求，则eNB对资源进行重配(释放)；Mode1/Mode2资源池发生变化时，eNB对涉及到的D2D UE所使用的资源进行重配(释放/更新)；低优先级的D2D UE的Mode1资源被抢占时，eNB向低优先级的D2D UE 发送D2D资源重配(释放)消息，使其释放Mode1资源，如果可能的话转而使用Mode2资源；D2D UE的能力/授权信息发生变化，则eNB对D2D UE所使用的资源进行重配。D2D UE接收到包含D2D资源修改或释放的D2D资源配置/重配消息后，向eNB反馈D2D资源配置/重配确认消息，具体流程如图15所示。
UE1进一步判断如果D2D资源配置信息仅包含第一资源分配方式对应的D2D发送资源配置修改，则所述UE更新后的第一资源分配方式对应的D2D发送资源池基于竞争的方式获取D2D资源进行D2D传输；如果UE1判断D2D资源配置信息仅包含第二资源分配方式对应的D2D发送资源配置修改，则UE1发起D2D调度请求/D2D缓冲区状态上报或所述UE等待D2D控制节点发送D2D资源授权或是半持续D2D资源激活控制信息；如果UE1判断D2D资源配置信息包含第一资源分配方式和或第二资源分配方式对应的D2D接收资源配置修改，则所述UE监听更新后的第一资源分配方式和或第二资源分配方式对应的D2D接收资源池；如果UE1判断D2D资源配置信息包含第一资源分配方式和第二资源分配方式对应的D2D资源配置修改，则UE1优先使用第二资源分配方式对应的D2D发送资源进行D2D发送；如果UE1判断D2D资源配置信息包含第一资源分配方式和或第二资源分配方式对应的D2D资源配置释放，则UE1释放所述第一资源分配方式和或第二资源分配方式对应的D2D资源信息，不再监听相应的资源池以及在相应的资源上进行发送。
实例10
在D2D UE使用Mode1资源进行D2D发现传输的过程中，有可能对蜂窝通信产生干扰，eNB可通过监听D2D发现消息初步定为干扰源UE，此外还有可能低优先级的D2D UE的mode1资源被强占，这两种情况下eNB可向UE发送D2D资源分配消息，指示D2D UE使用该专有Type2资源进行D2D发送。这两种情况下的模式切换都属于eNB发起。
模式切换也可以考虑由UE发起，如D2D UE检测到服务小区信号变差，在此期间，基站分配的mode1SPS D2D资源刚好过期，没来得及续约，或是D2D资源请求消息一直得不到响应，或是D2D UE一直由eNB动态分配资源，则D2D UE自主的选择使用mode2资源进行D2D发送。当服务小区的RRM测量变好以后，D2D UE可继续想eNB发送BSR请求eNB分配资源，具体如图16所示。
从以上的描述中，可以看出，本发明实施例实现了如下技术效果：可以根据需要以及D2D UE的状况为UE配置合适的D2D资源，确保D2D传输的顺利进行，该方 法即可应用于D2D发现也可应用于D2D通信。根据需要通过简单的流程为UE快速灵活的配置D2D资源，确保后续D2D通信的顺利进行。
显然，本领域的技术人员应该明白，上述的本发明实施例的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明实施例不限制于任何特定的硬件和软件结合。
以上所述仅为本发明实施例的优选实施例而已，并不用于限制本发明实施例，对于本领域的技术人员来说，本发明实施例可以有各种更改和变化。凡在本发明实施例的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明实施例的保护范围之内。
