Description

一种直接通信资源分配方法及装置
本申请要求在2018年10月31日提交中国专利局、申请号为201811291107.0、发明名称为“一种直接通信资源分配方法及装置”的中国专利申请的优先权，以及在2019年01月21日提交中国专利局、申请号为201910054760.3、发明名称为“一种直接通信资源分配方法及装置”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
本申请涉及无线通信技术领域，尤其涉及一种直接通信资源分配方法及装置。
背景技术
相互靠近的终端和终端之间允许直接进行终端之间的直接通信。如图1所示，为了便于描述，定义终端和终端之间的直接通信链路为Sidelink链路，其对应的无线接口称为Sidelink接口；网络与直接通信终端之间的蜂窝通信链路称之为Uu link，其对应的接口称为Uu接口。
直接通信的终端可以均是在网的，或者均是脱网的，还可以是部分终端在网，部分终端脱网。所谓在网即参与直接通信的终端位于3GPP直接通信载波覆盖范围内，所谓脱网即参与直接通信的终端不在3GPP直接通信载波覆盖范围内。
典型的直接通信场景包括如下三种：
1)单播通信
即终端之间一对一通信；
2)组播通信
一个终端一次可以给一个通信群组里的所有终端发送相同数据；当通信群组内的接收终端只有一个时，对应的方式为单播通信。单播通信可以看作是组播通信的特例。
3)广播通信
一个终端一次可以给所有附近的终端发送相同数据，广播通信不保证通信的可靠性。
目前，直接通信接口支持两种资源分配方式：
1)网络调度的资源分配模式
即由网络根据终端上报的Sidelink BSR(Buffer Status Reporting，缓冲区状态上报)为终端分配资源的方式。
2)终端自主选择的资源分配模式
即终端自行从预配置或者网络广播的发送资源中选择一个资源进行直接通信链路的数据发送。
对于直接通信接口，如果终端在网，无论是使用网络调度的资源分配模式还是终端自主选择的资源分配模式，其直接通信接口使用的资源都是受网络设备控制的，网络设备通过Uu接口控制直接通信接口分配的资源池(对应终端自主选择的资源分配模式)或者具体资源(对应网络调度的资源分配模式)。因此统称为基于Uu口的资源分配。
5G系统中，对于支持直接通信的终端其在直接通信接口的能力也有所不同，有的终端 在直接通信接口仅支持LTE(Long Term Evolution，长期演进)无线接入技术，有的终端在直接通信接口仅支持NR(New Radio，新空口)无线接入技术，还有的终端在直接通信接口即可以支持LTE无线接入技术，也可以支持NR无线接入技术。对于在直接通信接口仅支持一种无线接入技术的终端，毫无疑问，其在直接通信接口只能使用该无线接入技术，但是对于同时支持两种及以上无线接入技术的终端，当终端有直接通信需求时可以基于逻辑信道选择无线接入技术，也就是说直接通信接口上不同逻辑信道使用的无线接入技术可能不同。这种情况下就需要考虑如何保证直接通信资源分配节点分配的资源能够和终端直接通信接口上每个逻辑信道选择的无线接入技术相匹配。

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份实施例，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。
3GPP NR V2X立项文件中讨论到Uu接口辅助直接通信通信接口资源分配时，如表1所示，提出了三种场景：
表1
场景 Uu link Sidelink
1 LTE NR
2 NR NR
3 NR LTE
由上表可见，对于高能力的终端，其在直接通信接口可以支持多种无线接入技术，比如LTE Rel-14无线接入技术，LTE Rel-15无线接入技术和NR无线接入技术。对于同时支持两种及以上无线接入技术的终端，当终端有直接通信需求时可以基于逻辑信道选择无线接入技术，也就是说直接通信接口上不同逻辑信道使用的无线接入技术可能不同。这种情况下就需要考虑如何保证直接通信资源分配节点分配的资源能够和终端直接通信接口上每个逻辑信道选择的无线接入技术相匹配。
如图2所述，本申请实施例的直接通信接口资源分配系统包括：
资源分配管理节点10，用于向直接通信终端发送直接通信接口逻辑信道组配置指示信息，以指示使用不同的无线接入技术的逻辑信道分别对应不同的逻辑信道组；接收所述直接通信终端基于所述直接通信接口逻辑信道组配置指示信息上报的缓冲区状态报告(BSR)；根据逻辑信道组与无线接入技术的对应关系，在确定的无线接入技术所对应的物理资源上为直接通信终端分配直接通信接口发送资源。
直接通信终端20，用于接收资源分配管理节点发送的直接通信接口逻辑信道组配置指 示信息，所述直接通信接口逻辑信道组配置指示信息用于指示使用不同的无线接入技术的逻辑信道分别对应不同的逻辑信道组；根据所述直接通信接口逻辑信道组配置指示信息，确定直接通信接口逻辑信道对应的逻辑信道组。
本申请实施例直接通信终端接收直接通信资源分配管理节点发送的直接通信接口逻辑信道组配置指示信息，能够保证同一个逻辑信道组内所有逻辑信道使用相同无线接入技术。
可选地，直接通信终端还用于根据所述确定的直接通信接口逻辑信道对应的逻辑信道组，上报缓冲区状态报告(BSR)；接收无线资源分配管理节点根据所述BSR分配的直接通信接口发送资源。
直接通信终端在进行BSR上报时，可以使用同一个缓冲区状态报告媒体接入控制单元BSR MAC CE上报不同无线接入技术对应的BSR，或者使用独立的BSR MAC CE分别上报不同无线接入技术对应的BSR。具体可以根据BSR MAC CE的占用情况选择对应的上报方式。
资源分配管理节点接收直接通信终端使用同一个BSR MAC CE上报的不同无线接入技术对应的BSR，或者接收直接通信终端使用独立的BSR MAC CE分别上报不同无线接入技术对应的BSR。
在实施中，上述逻辑信道组配置指示信息包括两类信息，一类是不同无线接入技术对应的逻辑信道组标识，一类是逻辑信道组标识对应逻辑信道组参数信息，该逻辑信道组参数信息具体可以为该逻辑信道标识对应的无线接入技术中逻辑信道的相关参数信息。
直接通信终端可以根据每个逻辑信道组标识及对应的逻辑信道参数信息，结合本地直接通信接口的逻辑信道的相关参数信息，确定本地直接通信接口的逻辑信道的相关参数信息对应的逻辑信道组标识，并将确定的逻辑信道组标识上报给资源分配管理节点，从而使资源分配管理节点知道直接通信终端的直接通信接口逻辑信道支持的无线接入技术，从与该无线接入技术对应的物理资源上选择直接通信接口资源进行分配。
本申请提供的直接通信接口资源分配系统，能够保证直接通信资源分配节点分配的资源能够和终端直接通信接口上每个逻辑信道选择的无线接入技术相匹配，从而保证直接通信数据可以使用合理的无线接入技术进行发送。
作为一种可选的实施方式，上述直接通信接口逻辑信道组配置指示信息，为直接通信接口QoS(Quality of Service，服务质量)参数和逻辑信道组标识的映射关系，且同一逻辑信道组内的逻辑信道仅对应一种无线接入技术。
由于不同的无线接入技术对应不同的逻辑信道，每个逻辑信道具有对应的QoS参数，为了保证同一个逻辑信道组内所有逻辑信道使用相同无线接入技术，资源分配管理节点可以基于每个无线接入技术对应的所有逻辑信道的QoS参数，分别配置其和逻辑信道组标识的映射关系，并且不同无线接入技术对应的逻辑信道组标识是不同的，完成配置的逻辑信道组标识及对应QoS参数携带在配置直接通信接口逻辑信道组配置指示信息中，指示给直接通信终端。
可选地，直接通信终端向资源分配管理节点上报辅助信息，该辅助信息包括直接通信终端的直接通信接口每个逻辑信道对应的全部或者部分QoS参数。
资源分配管理节点接收直接通信终端上报的辅助信息，根据辅助信息中的直接通信终端的直接通信接口每个逻辑信道对应的全部或者部分QoS参数，可以确定上述全部或部分 QoS参数和逻辑信道组标识的映射关系，并指示给直接通信终端。
在实施中，上述直接通信接口QoS参数和逻辑信道组标识的映射关系，可以但不限于为如下任一映射关系：
1)每个数据包的优先级PPPP和逻辑信道组标识的映射关系；
在LTE Rel-14无线接入技术中，不同无线接入技术的逻辑信道QoS参数包括PPPP参数，因此，LTE Rel-14直接通信接口QoS参数和逻辑信道组标识的映射关系可以体现为PPPP和逻辑信道组标识(LCG ID)的映射关系。
2)每个数据包的可靠性PPPR和逻辑信道组标识的映射关系；
在LTE Rel-15无线接入技术中，不同无线接入技术的逻辑信道QoS参数包括PPPP和/或PPPR参数。因此，LTE Rel-15直接通信接口QoS参数和逻辑信道组标识的映射关系可以体现为PPPP和/或PPPR和LCG ID的映射关系。
3)新空口NR QoS参数和逻辑信道组标识的映射关系。
在新空口NR无线接入技术中，不同无线接入技术的逻辑信道QoS参数包括5QI参数。因此，新空口NR直接通信接口QoS参数和逻辑信道组标识的映射关系可以体现为5QI和LCG ID的映射关系。
在资源分配管理节点发送的上述直接通信接口逻辑信道组配置指示信息，为直接通信接口QoS参数和逻辑信道组标识的映射关系时，直接通信终端20接收到上述直接通信接口逻辑信道组配置指示信息后，根据直接通信终端的直接通信接口每个逻辑信道的QoS参数，及逻辑信道组标识与QoS参数的映射关系，确定直接通信接口逻辑信道与无线接入技术对应的逻辑信道组标识的映射关系。
在实施中，直接通信终端20在直接通信接口的逻辑信道是已知，且本地存储有逻辑信道与QoS参数的映射关系表，直接通信终端20可以确定每个逻辑信道的QoS参数，将每个逻辑信道的QoS参数与每个逻辑信道组标识对应的QoS参数进行比较，如果确定某个逻辑信道的QoS参数满足其中某个逻辑信道组标识对应的QoS参数的全部要求，确定该逻辑信道采用该逻辑信道组标识对应的无线接入技术。
作为另一种可选的实施方式，上述直接通信接口逻辑信道组配置指示信息，为直接通信接口逻辑信道和逻辑信道组标识的映射关系，且同一逻辑信道组内的逻辑信道仅对应一种无线接入技术。
采用该实施方式时，由于资源分配管理节点不知道直接通信终端本地的直接通信接口逻辑信道，需要直接通信终端需要上报辅助信息，作为一种可选的实施方式，直接通信终端还用于向资源分配管理节点上报辅助信息，该辅助信息包括所述直接通信终端的直接通信接口每个逻辑信道标识，及其对应的QoS参数。
资源分配管理节点用于接收直接通信终端上报的辅助信息，该辅助信息包括直接通信终端的直接通信接口每个逻辑信道标识，及其对应的QoS参数；根据直接通信终端上报的辅助信息确定直接通信接口逻辑信道组配置指示信息。
在实施中，由于资源分配管理节点本地存储有不同逻辑信道及对应的QoS参数映射表，通过该映射表，可以根据直接通信终端上报的逻辑信道标识确定对应的逻辑信道，根据不同无线接入技术对应的逻辑信道，确定直接通信终端的直接通信接口的逻辑信道所对应的逻辑信道组，从而将直接通信终端的直接通信接口的逻辑信道及对应的逻辑信道组标识，作为直接通信接口逻辑信道组配置指示信息指示给直接通信终端。
作为另一种可选的实施方式，直接通信终端向资源分配管理节点上报的辅助信息包括直接通信终端直接通信接口每个逻辑信道标识，及其对应的QoS参数和每个逻辑信道期望使用的无线接入技术。
在实施中，由于资源分配管理节点本地存储有不同逻辑信道及对应的QoS参数映射表，根据该映射表可以确定直接通信终端上报的QoS所映射的逻辑信道，根据不同无线接入技术对应的逻辑信道，确定直接通信终端的直接通信接口的逻辑信道所对应的逻辑信道组，确定直接通信接口逻辑信道与期望的无线接入技术对应的逻辑信道组标识的映射关系，从而将直接通信接口逻辑信道与期望的无线接入技术对应的逻辑信道组标识的映射关系，作为直接通信接口逻辑信道组配置指示信息指示给直接通信终端。
可选地，直接通信终端基于直接通信接口逻辑信道组配置指示信息，确定本地的逻辑信道对应的逻辑信道组标识，根据本地的逻辑信道及对应的逻辑信道组标识组织Sidelink BSR，并且当满足Sidelink BSR上报触发条件后进行Sidelink BSR上报，从而使资源分配管理节点知道直接通信终端的本地逻辑信道及对应的逻辑信道组标识。
可选地，直接通信资源分配管理节点接收到终端的Sidelink BSR上报之后还包括：根据Sidelink BSR，基于逻辑信道组与无线接入技术的对应关系，确定直接通信终端直接通信接口的逻辑信道对应的无线接入技术，在确定的无线接入技术所对应的物理资源上为直接通信终端分配直接通信接口传输资源。
直接通信资源分配管理节点确定无线接入技术和物理资源的对应关系有两种方式：
一种方式是，将无线接入技术和物理资源的对应关系预配置给直接通信资源分配管理节点和终端，直接通信资源分配管理节点根据预配置信息，确定无线接入技术对应的物理资源，此时资源分配管理节点向直接通信终端发送的调度信令或者调度信令调度的PDSCH(Physical Downlink Shared Chanel，物理下行共享信道)中不需要携带无线接入技术指示信息；
另外一种方式是，资源分配管理节点动态确定无线接入技术和物理资源的对应关系，这种情况下，资源分配管理节点通过Uu接口传输的直接通信接口调度信令或者在Uu接口传输的直接通信接口调度信令调度的PDSCH，向直接通信终端指示直接通信接口分配的物理资源和无线接入技术或QoS参数或逻辑信道的映射关系。
可选地，直接通信终端通过Uu接口传输的直接通信接口调度信令，或者在Uu接口传输的直接通信接口调度信令调度的PDSCH，接收所述资源分配管理节点指示的直接通信接口分配的物理资源与无线接入技术，或直接通信接口分配的物理资源与QoS参数，或直接通信接口分配的物理资源与逻辑信道的映射关系。

步骤2，直接通信终端确定直接通信接口的逻辑信道和逻辑信道组的映射关系。
直接通信终端接收到直接通信资源分配管理节点发送的直接通信接口逻辑信道组配置指示信息之后，如果配置指示信息包括逻辑信道的QoS参数及对应的逻辑信道组标识，则根据本地的直接通信接口逻辑信道与QoS参数的映射关系，确定逻辑信道和逻辑信道组 标识的映射关系，比如逻辑信道的QoS参数是PPPP,那么就根据所述指示信息中指示的PPPP和逻辑信道组标识的映射关系确定逻辑信道对应的逻辑信道组标识；如果逻辑信道的QoS参数是5QI,那么就根据所述指示信息中指示的5QI和逻辑信道组标识的映射关系确定逻辑信道对应的逻辑信道组标识。
步骤3，直接通信终端通过直接通信接口进行BSR上报。
直接通信终端基于直接通信接口逻辑信道组配置指示信息组织Sidelink BSR，并且当满足Sidelink BSR上报触发条件后，进行Sidelink BSR上报。
步骤4，资源分配管理节点为直接通信终端进行直接通信接口资源分配。
直接通信资源分配管理节点接收到终端的Sidelink BSR上报之后还包括：基于逻辑信道组和无线接入技术的对应关系，在各个无线技术对应的物理资源上为终端分配直接通信接口传输的资源。

对于前者，不同无线接入技术使用的QoS参数可以不同，直接通信资源分配管理节点可以根据QoS参数的不同或者直接通信资源分配管理节点存储的QoS参数和无线接入技术的映射关系，确定直接通信终端的逻辑信道对应的无线接入技术；对于后者，直接通信资源分配管理节点可以直接根据终端上报的无线接入技术确定逻辑信道对应的无线接入技术。
步骤1，直接通信资源分配管理节点向直接通信终端发送的直接通信接口逻辑信道组配置指示信息。
直接通信资源分配管理节点发送的直接通信接口逻辑信道组配置指示信息，为直接通信接口逻辑信道和逻辑信道组标识的映射关系，并且需要保证使用不同无线接入技术的逻辑信道对应的逻辑信道组标识不同。
步骤2，直接通信终端确定直接通信逻辑信道和逻辑信道组的映射关系。
直接通信终端接收到直接通信资源分配管理节点发送的直接通信接口逻辑信道组配置指示信息之后，确定逻辑信道和逻辑信道组标识的映射关系。
