超密集组网是未来移动通信系统发展的一个趋势，在超密集组网情况下，为了实现对大量分布式处理节点的统一控制面管理，需要将部分协议功能进行集中式处理，这样就形成了集中处理节点和分布式处理节点的双层接入网架构。其中分布式处理节点也称为TRP(Transmission Reception Point，发送接收节点)，集中处理节点也称为CU(Central Unit，集中处理节点)或者NR eNB(New RAT eNB，新接入技术基站)。对于集中处理节点，根据功能不同，还可以进一步划分为集中处理节点的控制面和集中处理节点的用户面。
基于上述描述，未来移动通信系统的网络架构示意图如图5所示。其中TRP支持single beam(单波束)或者multiple beam(多波束)传输。对于single beam，beam测量结果等于对TRP的测量结果；对于multiple beam，由于一个TRP下有多个beam，因此beam测量结果和TRP测量结果是不等同的。
在5G网络下，TRP的部署比较密集。如果处于连接状态下的移动UE长时间没有数据发送，那么网络侧不能准确跟踪UE的位置。当有下行数据到达时，网络侧将无法确定通过哪个TRP和/或beam来进行下行数据的发送。因此需要考虑引入UE服务TRP和/或beam跟踪机制，以便在下行数据到达时，能够实现网络侧选择合适的下行TRP和/或beam来进行下行数据的发送。
本公开的技术方案由网络侧对数据传输资源进行分组，分为若干个数据传输资源Group(组)，并将数据传输资源和数据传输资源Group的映射关系配置给终端。当用户终端发生位置变化时，用户终端上报测量结果给网络侧，以便网络侧更新用户终端当前对应的数据传输资源Group，当有下行数据到达，网络侧根据用户终端上报的测量结果选择合适的下行数据传输资源或者数据传输资源Group进行数据发送。其中，用户终端上报测量结果可以采用RRC信令，也可以采用MAC信令，比如引入新的MAC控制单元(MAC CE)信令。
上述数据传输资源包括TRP和beam，下面以数据传输资源为TRP为例，结合具体的实施例对本公开的技术方案进行进一步介绍。
如图6所示，本实施例的数据传输方法包括以下步骤501至步骤505。
步骤501：基于网络配置TRP与TRP Group之间的映射关系。
具体地，由CU配置TRP与TRP Group之间的映射关系，配置原则为邻近原则，即将距离最近的一个或多个TRP划分为一组TRP。为了便于标识TRP和TRP Group，可以引入TRP ID(标识)和TRP Group ID。
基于网络配置，即对于网络中所有用户终端而言，TRP和TRP Group的映射关系都是相同的。对于基于网络配置的情况，TRP和TRP Group的映射关系可以由CU通过广播消息或者专用信令通知终端。进一步，对于通过广播消息将映射关系通知给用户终端的情况，用户终端可以通过on-demand SI来获取映射关系。
步骤502：CU向终端发送测量配置消息。
测量配置消息中包括有测量对象和上报配置，测量对象为TRP Group中的每个TRP，每个TRP以TRP ID标识，TRP Group以TRP Group来标识，具体地，在测量配置消息中包括有TRP Group标识，即指示用户终端对TRP Group标识对应的TRP Group中的TRP进行信道质量测量。上报配置(report configuration)包括用户终端发送测量上报消息的触发类型，触发类型分为事件触发上报和周期触发上报，每个上报配置拥有单独的ID。
事件触发类型的上报配置会配给某一个事件的门限值，可选的还可以配置满足触发条件的持续时间(Time to Trigger)。周期性触发类型的上报配置会配给周期性触发的目的。
对于事件触发类型上报，触发条件可以包含但不限于触发条件1至触发条件6中的至少一个。
触发条件1：当前为用户终端服务的TRP Group内一个或者多个(多个包含全部)TRP的信道质量都低于门限1。
触发条件2：邻TRP Group内一个或者多个(多个包含全部)TRP的信道质量高于门限2。
触发条件3：邻TRP Group中信道质量最好的TRP的信道质量优于当前为用户终端服务的TRP Group中信道质量最好的TRP的信道质量。
触发条件4：当前为用户终端服务的TRP Group中信道质量最好的TRP的信道质量低于门限1，邻TRP Group中信道质量最好的TRP的信道质量高于门限2。
触发条件5：邻TRP Group中所有TRP信道质量的均值优于当前为用户终端服务的TRP Group中所有TRP的信道质量的均值。
触发条件6：邻TRP Group中所有TRP信道质量的均值质量低于门限1，当前为用户终端服务的TRP Group中所有TRP的信道质量高于门限2。
进一步地，测量配置消息还包括其他参数，比如包括测量量配置，测量开启门限以及速度缩放参数等其他参数。在测量配置消息中，每个测量对象都有自己的测量标识(measurement ID)，可以同时关联一个测量对象与上报配置，如果达到了测量开启门限，用户终端会根据测量标识的有无来进行测量，对有测量标识的测量对象来进行测量。
步骤503：用户终端对测量对象进行信道质量测量，并向CU发送测量上报消息。
测量上报消息包含如下部分或者全部：测量标识，每个TRP的测量结果或者基于TRP测量结果确定的TRP Group的测量结果。如果CU下发的测量配置消息中还包括预设选择条件，则测量上报消息还包括满足预设选择条件的TRP ID或者TRP Group ID等。是否上报满足预设选择条件的TRP或者TRP Group的测量结果取决于CU是否配置终端上报这些信息。
在每一个测量标识下，分为测量评估与组织上报两个过程。
测量评估，即终端通过测量，寻找到某个测量对象中满足上报配置的TRP Group，进行评估，当小区在一定时间内(Time To Trigger)都满足预设选择条件，将被包含在上报列表中；一旦有新的TRP Group进入上报列表，就会触发上报过程。组织上报：即填写测量上报消息的过程，需要填写测量标识，当前TRP或者TRP Group测量信息，邻TRP Group测量信息。邻TRP Group测量信息的获得过程是，将测量评估中的上报列表里包含的TRP Group按照配置中给定的上报测量量进行排序，比如按从高到底的顺序填入测量上报消息。测量量可以包括参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Singnal Received Quality，RSRQ)、接收信号强度指示(Received Signal Strength Indication，RSSI)和信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)中的至少一个。
用户终端向CU发送测量上报消息可以使用RRC(无线资源控制)信令。 为了进一步节省时延，也可以由用户终端直接根据测量结果确定信道质量最好的TRP Group，直接通过MAC CE信令上报给CU，MAC CE需要定义新的LCID(逻辑信道标识)，并携带所选择的TRP Group ID。
步骤504：CU根据测量上报消息选择向用户终端发送下行数据所使用的TRP Group或TRP。
如果用户终端向CU发送测量上报消息使用的是RRC信令，测量上报消息中包括有TRP Group的信道质量测量结果，那么步骤504具体包括：选择信道质量最好的TRP进行下行数据发送；或选择包括信道质量最好的TRP的TRP Group进行下行数据发送；或选择包括信道质量均值最好的TRP的TRP Group进行下行数据发送。
如果用户终端向CU发送测量上报消息使用的是MAC信令，测量上报消息中包括有用户终端所确定的TRP或TRP Group的标识，则直接根据MAC信令中携带的TRP Group ID确定下行TRP Group进行数据发送即可。
步骤505：当有下行数据到达，CU通过所选择的TRP Group或TRP向终端发送下行数据。
具体地，下行数据发送包括下行业务数据或者控制信息(比如PDCCH(物理下行控制信道)order)的发送。为了保证用户终端和CU理解的一致性，用户终端也按照和CU相同的原则选择要监听的TRP或者TRP Group。
在实施例中，用户终端对TRP组中的TRP进行信道质量测量，并基于测量结果向集中处理节点发送测量上报消息。集中处理节点根据用户终端上报的测量上报消息可以追踪到用户终端的位置，从而选择合适的TRP组或TRP来将下行数据发送给终端，通过该合适的TRP组或TRP进行下行数据的发送，能够保证5G网络的通信质量。
上述实施例以数据传输资源为TRP为例对无线网络中的数据传输方法进行介绍，当然，数据传输资源还可以为beam，只要将上述实施例中的TRP替换为beam即可，在此不再赘述。
如图7所示，本公开的实施例还提供一种数据传输方法，该数据传输方法包括以下步骤601至步骤605。
步骤601：基于用户终端配置TRP与TRP Group之间的映射关系。
具体地，由CU配置TRP与TRP Group之间的映射关系，配置原则为邻近原则，即将距离最近的一个或多个TRP划分为一组TRP，为了便于标识TRP和TRP Group，可以引入TRP ID(标识)和TRP Group ID。
基于用户终端配置，即对于网络下的不同用户终端而言，TRP与TRP Group之间的映射关系可以相同，也可以不同。对于基于用户终端配置的情况，TRP与TRP Group之间的映射关系只能通过专用信令通知用户终端。
进一步地，对于基于用户终端配置的方式，网络可以基于用户终端的移动速度等因素确定TRP Group的大小。比如，对于高速移动的用户终端，配置较大的TRP Group，即TRP Group包括较多的TRP；对于低速移动的用户终端，配置较小的TRP Group，即TRP Group包括较少的TRP。
步骤602：CU向用户终端发送测量配置消息。
测量配置消息中包括有测量对象和上报配置，测量对象为TRP Group中的每个TRP，每个TRP以TRP ID标识，TRP Group以TRP Group来标识，具体地，在测量配置消息中包括有TRP Group标识，即指示用户终端对TRP Group标识对应的TRP Group中的TRP进行信道质量测量。上报配置(report configuration)包括用户终端发送测量上报消息的触发类型，触发类型分为事件触发上报和周期触发上报，每个上报配置拥有单独的ID。
事件触发类型的上报配置会配给某一个事件的门限值，可选的还可以配置满足触发条件的持续时间(Time to Trigger)。周期性触发类型的上报配置会配给周期性触发的目的。
对于事件触发类型上报，触发条件可以包含但不限于触发条件1至触发条件6中的至少一个。
触发条件1：当前为用户终端服务的TRP Group内一个或者多个(多个包含全部)TRP的信道质量都低于门限1。
触发条件2：邻TRP Group内一个或者多个TRP(多个包含全部)的信道质量高于门限2。
触发条件3：邻TRP Group中信道质量最好的TRP的信道质量优于当前为用户终端服务的TRP Group中信道质量最好的TRP的信道质量。
触发条件4：当前为用户终端服务的TRP Group中信道质量最好的TRP的 信道质量低于门限1，邻TRP Group中信道质量最好的TRP的信道质量高于门限2。
触发条件5：邻TRP Group中所有TRP信道质量的均值优于当前为用户终端服务的TRP Group中所有TRP的信道质量的均值。
触发条件6：邻TRP Group中所有TRP信道质量的均值质量低于门限1，当前为用户终端服务的TRP Group中所有TRP的信道质量高于门限2。
进一步地，测量配置消息还包括其他参数，比如包括测量量配置，测量开启门限以及速度缩放参数等其他参数。在测量配置消息中，每个测量对象都有自己的测量标识(measurement ID)，可以同时关联一个测量对象与上报配置，如果达到了测量开启门限，用户终端会根据测量标识的有无来进行测量，对有测量标识的测量对象来进行测量。
步骤603：用户终端对测量对象进行信道质量测量，并向CU发送测量上报消息。
测量上报消息包含内容包含如下部分或者全部：测量标识，每个TRP的测量结果或者基于TRP测量结果确定的TRP Group的测量结果。如果CU下发的测量配置消息中还包括预设选择条件，则测量上报消息中还包括满足预设选择条件的TRP ID或者TRP Group ID等。是否上报满足预设选择条件的TRP或者TRP Group的测量结果取决于CU是否配置用户终端上报这些信息。
在每一个测量标识下，分为测量评估与组织上报两个过程：测量评估和组织上报。
测量评估，即用户终端通过测量，寻找到某个测量对象中满足上报配置的TRP Group，进行评估，当小区在一定时间内(Time To Trigger)都满足预设选择条件，将被包含在上报列表中；一旦有新的TRP Group进入上报列表，就会触发上报过程。
组织上报：即填写测量上报消息的过程，需要填写测量标识，当前TRP或者TRP Group测量信息，邻TRP Group测量信息。邻TRP Group测量信息的获得过程是，将测量评估中的上报列表里包含的TRP Group按照配置中给定的上报测量量进行排序，比如按从高到底的顺序填入测量上报消息。测量量可以包括参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、接收 信号强度指示(RSSI)和信号与干扰加噪声比(SINR)中的至少一个。
用户终端向CU发送测量上报消息可以使用RRC(无线资源控制)信令。为了进一步节省时延，也可以由用户终端直接根据测量结果确定信道质量最好的TRP Group，直接通过MAC CE信令上报给CU，MAC CE需要定义新的LCID(逻辑信道标识)，并携带所选择的TRP Group ID。
步骤604：CU根据测量上报消息选择向用户终端发送下行数据所使用的TRP Group或TRP。
如果用户终端向CU发送测量上报消息使用的是RRC信令，测量上报消息中包括有TRP Group的信道质量测量结果，那么选择过程具体包括：选择信道质量最好的TRP进行下行数据发送；或选择包括信道质量最好的TRP的TRP Group进行下行数据发送；或选择包括信道质量均值最好的TRP的TRP Group进行下行数据发送。
如果终端向CU发送测量上报消息使用的是MAC信令，测量上报消息中包括有用户终端所确定的TRP或TRP Group的标识，则直接根据MAC信令中携带的TRP Group ID确定下行TRP Group进行数据发送即可。
步骤605：当有下行数据到达，CU通过所选择的TRP Group或TRP向终端发送下行数据。
具体地，下行数据发送包括下行业务数据或者控制信息(比如PDCCH(物理下行控制信道)order)的发送。为了保证用户终端和CU理解的一致性，用户终端也按照和CU相同的原则选择要监听的TRP或者TRP Group。
在实施例中，用户终端对TRP组中的TRP进行信道质量测量，并基于测量结果向集中处理节点发送测量上报消息。集中处理节点根据用户终端上报的测量上报消息可以追踪到用户终端的位置，从而选择合适的TRP组或TRP来将下行数据发送给用户终端，通过该合适的TRP组或TRP进行下行数据的发送，能够保证5G网络的通信质量。
上述实施例以数据传输资源为TRP为例对无线网络中的数据传输方法进行介绍，当然，数据传输资源还可以为beam，只要将上述实施例中的TRP替换为beam即可，在此不再赘述。
需要说明的是，本公开图2和图4所示的实施例中提供的装置是能够对 应实现上述方法实施例提供的数据传输方法的装置，故上述方法实施例提供的基于数据传输方法的所有实施例均可对应适用于该图2和图4所示的实施例，且均能达到相同或相似的有益效果。
