Description

一种上行信号的响应方法及装置 技术领域
本发明涉及无线通信领域，更具体地，涉及一种上行信号的响应方法及装置。
背景技术
现有无线通信系统的无线资源管理通常采用基于下行信号的测量方式，即基站发送下行参考信号，终端设备测量该基站发送的参考信号的RSRP(Reference Signal Received Power，参考信号接收功率)/RSPQ(Reference Signal Received Quality，参考信号接收质量)等参数，并将测量结果上报给基站，由基站根据测量结果来决定终端设备的切换和移动。
在下一代无线通信系统中，即5G通信系统，也称为NR(New Radio)系统，多个TRP(Transmission Reception Point，传输接收点)可以组成一个超级小区(Hyper cell)，Hyper cell内部的TRP共享一个相同的小区ID(Hyper cell ID)。终端设备通过发送上行信号，让Hyper cell内部的TRP进行位置跟踪，因此终端设备在Hyper cell内部移动时，不需要调用层3信令，仅仅通过层1信令即可完成；另外网络寻呼也可以在最近的TRP进行，避免在更大的跟踪区域进行，大大降低了终端设备移动带来的信令开销。如图1所示，左边Hyper cell包括9个TRP，右边Hyper cell包括8个TRP。Hyper cell可以是NR基站(eNB/gNB)的服务范围，即一个NR基站可以包括多个TRP。Hyper cell的多个TRP通过回程链路连接中心控制器(center unit，CU)，多个CU通过S1-C接口进行通信。
NR系统中，基站可以包括一个或多个TRP，小区可以为一个或多个TRP形成的覆盖范围。为了减小无线资源管理对网络发送频繁的、固定的下行参考信号的依赖，提升系统效率，引入基于上行信号的测量方法，即终端设备发送上行信号，由终端设备关联的基站或TRP以及相邻基站或TRP对该终端设备发送的上行信号进行测量，并对各基站或TRP的测量结果进行比较和判决，以决定终端设备切换到合适的小区进行服务。使用上行信号测量使得网络可以对终端设备进行跟踪，不仅可以使基站或TRP跟踪到终端设备当前所处位置，还可以知道哪个基站或TRP可以提供当前最好的传输。使用上行测量还可以实现终端设备快速的接入，降低下行寻呼消息发送范围和寻呼信令开销，提升网络性能。但目前终端设备并不能获知网络(基站或TRP)对其跟踪的情况，进一步的，终端设备也不能根据网络对其跟踪的情况对发送的上行信号进行调整。

相应的，上述方法中终端设备执行的方法包括：向基站或传输接收点TRP发送用于跟踪该终端设备的上行信号；接收所述基站或TRP发送的下行跟踪响应消息，所述下行跟踪响应消息包括以下至少一种：所述基站或TRP对该终端设备跟踪的状态信息、该终端设备发送上行跟踪信号所需的时间提前量信息、该终端设备发送上行信号所需的功率调整信息、该终端设备的接入控制信息；进一步的，终端设备可以根据上述信息对上行信号的发送进行相应的调整。
为了满足移动通信系统的大容量及高速率的传输需求，NR系统引入大于6GHz的高频频段进行通信，以利用其大带宽、高速率的传输特性，由于高频通信的高路损，需采用窄波束来保证传播距离和高波束增益，因此，针对高频基站或TRP，与终端设备的通信是在对准的波束上进行，高频基站或TRP在收到终端设备通过上行波束发送的上行跟踪信号(UL tracking signal)或上行参考信号(UL reference signal)后，通过所述上行波束关联的下行波束向该终端设备发送下行跟踪响应消息，还可以用于通知终端设备其被所述高频基站或高频TRP跟踪 的波束信息，可以用6比特的Beam info字段来指示，如Beam ID，或symbol index来隐式指示beam ID。
相应的，上述方法中终端设备执行的方法包括：终端设备通过上行波束向高频基站或高频TRP发送用于跟踪该终端设备的上行信号；在所述上行波束关联的下行波束上接收高频基站或高频TRP的发送下行跟踪响应消息，所述基站或TRP对该终端设备跟踪的状态信息、该终端设备发送上行跟踪信号所需的时间提前量信息、该终端设备发送上行信号所需的功率调整信息、该终端设备的接入控制信息、该终端设备被所述高频基站或高频TRP跟踪的波束信息；进一步的，终端设备可以根据上述信息对上行信号的发送进行相应的调整。

下行跟踪响应消息可以在PDSCH(physical downlink shared channel,下行共享物理信道)中传输，并由寻呼消息对终端设备进行指示；下行跟踪响应消息也可以在一个新定义的信道中传输，该信道的发送时隙遵从基站或TRP的参数配置。下行跟踪响应消息中包含至少一个终端设备或一个终端设备组的下行跟踪响应消息。
用寻呼消息去指示时，可以用寻呼指示标识或定义一个新的跟踪指示标识，用于通知终端设备有下行跟踪响应消息的信息；终端设备/终端设备组在寻呼时刻(Paging Occasion)里的子帧中搜索寻呼指示标识，如P-RNTI(paging radio network temporary identifier，寻呼无线网络临时标识)或新的跟踪指示标识，如TRA-RNTI(Tracking Acknowledge radio network temporary identifier,跟踪响应无线网络临时标识)，P-RNTI或TRA-RNTI可以占用PDCCH(physical downlink control channel，物理下行控制信道)资源，当收到P-RNTI或TRA-RNTI时，终端设备/终端设备组根据P-RNTI/TRA-RNTI对应资源指示获知对应的时频资源，并在对应的时频资源上去解码PDSCH内容，获得对应于该终端设备标识/终端设备组的下行跟踪响应消息。
用新定义的信道去指示时，终端设备在TRA Occasion(Tracking Acknowledge Occasion,跟踪响应时刻)，即：下行跟踪响应消息的发送时隙，的子帧中搜索PDCCH信道里的跟踪指示标识，如新定义的TRA-RNTI，其中所述TRA-RNTI用于通知终端设备有下行跟踪响应消息的信息。当收到TRA-RNTI时，终端设备/终端设备组根据TRA-RNTI对应资源指示获知对应的时频资源，并在对应的时频资源上去解码PDSCH内容，获得对应于该终端设备标识/终端设备组的下行跟踪响应消息。
或者，终端设备在TRA Occasion里面的子帧中搜索新定义的PTRANCH(Physical Tracking Acknowledge Notification Channel，物理跟踪响应消息通知信道)，该信道上包含对应于该终端设备标识终端设备组的下行跟踪响应消息。
上述方式中，TRA Occasion的发送时隙可以由基站/TRP通过RRC(radio resource control)消息进行配置。
下面结合附图对本发明实施例提出的上行信号的响应方法做进一步说明，参考图2，该方法包括：
101，基站或TRP向终端设备下发上行信号配置信息和/或下行跟踪响应消息配置信息。
终端设备接入某个基站或TRP后，这里的TRP可以为一个或多个，基站或TRP向终端设 备下发上行信号配置信息，以通知终端设备以什么方式发送上行跟踪信号或上行参考信号；终端接收后，便可根据该配置信息发送上行信号。
另外，基站或TRP向终端设备下发下行跟踪响应消息配置信息，以通知终端设备以什么方式接收基站或TRP发送下行跟踪响应消息；例如：基站或TRP通过在RRC消息中(如RRC重配置消息RRC reconfiguration)携带下行跟踪响应消息的配置信息来通知终端设备，包括下行跟踪响应消息的发送方式(周期发送、或事件触发)，发送周期，发送时隙，触发类型等一个或多个；终端接收后，便可根据该配置信息接收基站或TRP发送的上行信号。
下行跟踪响应消息的配置信息指示的发送方式有2种：
a)周期发送的方式，基站或TRP间隔周期T时间，在某个发送时隙(TO，Transmission Occasion)内，发送下行跟踪响应消息；
b)事件触发的方式，基站或TRP可以在某个特定的事件的触发下，发送下行跟踪响应消息；例如：事件可以包括但不限于以下任意一种或多种：终端设备的时间提前量需要调整；终端设备的功率需要调整；终端设备的移动速度超过阈值，TRP或基站接收到多个上行跟踪信号，即上行跟踪信号数量超过设定阈值等。
采用事件触发方式时，可以在寻呼期间或发送时隙中，通过寻呼消息或其它指示消息指示终端设备读取下行跟踪响应消息。
终端设备接收到下行跟踪响应消息的配置信息，可以确定接收下行跟踪响应消息的方式，如周期性接收；或接收寻呼消息或其它指示消息，并根据其指示进行接收。
102、终端设备进入非激活Inactive状态；
该步骤是可选步骤，为了节省终端设备的电量；终端设备的Inactive状态可以是在RRC IDLE和RRC ACTIVE状态之外的一种新状态。在该状态下，TRP/基站和保持有终端设备的上下文，并且终端设备会被网络分配一个专用的终端设备ID，该终端设备ID在Hyper cell内部是唯一标识。当Inactive状态下的终端设备希望进行上行数据传输时，无需发起状态转移到ACTIVE状态。当网络希望向Inactive状态下的终端设备发起下行数据传输时，也可以直接在寻呼期间来寻呼该终端设备，或者是在某个期间(如寻呼期间)通过资源指示的方式进行下行传输。
103、终端设备向基站或TRP发送上行信号，以便于接收到的基站或TRP对该终端设备进行跟踪；
终端设备可以根据照步骤101中上行跟踪信号配置信息向基站或TRP发送上行跟踪信号或上行参考信号。
104、基站或TRP向终端设备发送下行跟踪响应消息；
在对应的发送时隙，终端设备接收到下行跟踪响应消息，可以根据下行跟踪响应消息包括的内容对上行信号的发送进行调整。
例如：可以根据其中的ACK字段确认网络(即基站或TRP)是否跟踪到该终端设备的状态信息，若被网络跟踪到，则可以继续按照上行跟踪信号的配置信息进行上行跟踪信号的发送；若在设定的时间内未收到基站或TRP发送的下行跟踪响应消息，则表示没有被网络跟踪到，则取消上行跟踪信号或参考信号的发送，或者提高上行跟踪信号或上行参考信号的发送频次以增加被跟踪到的可能性，或者终端设备转换为采用下行测量方式；进一步的，终端设备还可以进入IDLE状态，以节省电量。
另外，在对应的发送时隙，终端设备接收到下行跟踪响应消息，还可以根据其中的TA字 段获取网络(即基站或TRP)指示的时间提前量(TA)信息，并根据TA来调整上行跟踪信号的发送时间，使得TRP或基站接收到的上行跟踪信号或参考信号的时间满足一定范围。
另外，在对应的发送时隙，终端设备接收到下行跟踪响应消息，还可以根据其中的PC字段获知网络(即基站或TRP)指示的功率控制(power control，PC)信息，并根据PC信息来调整上行跟踪信号的发送功率，使得TRP或基站接收到的上行跟踪信号或参考信号的功率满足一定范围。
另外，在对应的发送时隙，终端设备接收到下行跟踪响应消息，还可以根据其中的AC字段获知(即基站或TRP)指示的接入控制(Access control)信息，并根据AC信息来调整终端设备的状态，例如：从Inactive状态进入Idle态，便于省电。
如果发送下行跟踪响应消息的是高频基站或TRP，终端设备接收下行跟踪响应消息，还可根据其中的beam info字段获知高频基站或TRP指示的发送上行跟踪信号的波束beam信息，即跟踪到该终端设备的beam信息，使得终端设备确定最佳的发送上行跟踪信号的beam方向，以有利于在后续发送上行跟踪信号时进行beam选择。
上述实施例中公开的上行信号的响应方法，通过基站或TRP向终端设备发送下行跟踪响应消息，通知终端设备其被网络跟踪的状态，还可以指示终端设备进行后续上行信号的发送。
针对高频基站或TRP的上行信号的响应方法包括：
高频基站或高频TRP接收终端设备采用上行波束发送的用于跟踪该终端设备的上行信号；
在所述上行波束关联的下行波束上向所述终端设备发送下行跟踪响应消息，所述下行跟踪响应消息包括以下至少一种：所述基站或TRP对该终端设备跟踪的状态信息、该终端设备发送上行跟踪信号所需的时间提前量信息、该终端设备发送上行信号所需的功率调整信息、该终端设备的接入控制信息、该终端设备被所述高频基站或高频TRP跟踪的波束信息。
与前面实施例不同的是，高频基站或TRP与终端设备的通信通过波束对进行，上行信号及下行跟踪响应消息的发送通过相应的波束进行，同样，上行信号配置信息及下行跟踪响应消息配置信息的发送也通过相应的波束进行，其它特性与前述实施例类似，不再详述。
另外，针对高频NR的系统，由于高频TRP/基站与终端设备的通信在对应的波束对上进行，例如终端设备采用波束扫描的方式在不同的波束上发送上行信号(上行跟踪信号或上行参考信号)，在终端设备以beam扫描的发送方式完成上行跟踪信号发送后，基站或TRP再以波束扫描的方式进行下行响应跟踪消息的发送。该下行跟踪响应消息的发送可以是在每个上行跟踪信号的beam方向所对应的下行beam上进行，也可以在最优的一个或者多个beam方向上进行发送，一个上行beam可以对应一个或多个下行beam。该下行响应跟踪消息可以包括一个终端设备或一个终端设备组的下行响应跟踪消息。另外，部分信号较差的上行波束方向可以不再进行下行跟踪响应消息的发送。
在一个实施例中，该高频基站或高频TRP在接收终端设备采用多个上行波束发送的用于跟踪该终端设备的上行信号后，再针对该多个上行波束发送的上行信号，分别采用多个上行波束关联的下行波束发送所述下行跟踪响应消息，例如：可以当终端设备轮询完所有发送波束，然后再针对各个发送波束发送的上行信号，采用关联的下行波束分别发送下行跟踪响应消息。
例如：如图3所述，终端设备分别在波束B1-Bk以波束扫描的方式发送上行跟踪信号(或上行参考信号)，完成波束扫描后，即波束B1-Bk均发送了上行跟踪信号后，再针对各个波束 发送的上行跟踪信号，基站或TRP以波束扫描的方式针对波束B1-Bk采用相应的下行波束发送下行跟踪响应消息。
上述方式的好处是避免终端设备频繁的进行发送和接收波束切换，适合Beam数目较少的情况。
还有另外一种高频基站或TRP发送下行跟踪响应消息的方式，针对每一个beam方向上发送的上行跟踪信号，在下行对应的方向上进行下行跟踪响应消息的发送。该下行响应跟踪消息的发送可以是TRP可以接收到上行跟踪信号的方向所对应的下行beam方向上发送，也可以是每个下行beam方向都进行发送。该下行响应跟踪消息至少包括一个终端设备或一个终端设备组的下行响应跟踪消息。
在另一个实施例中，该高频基站或高频TRP每接收终端设备采用一个上行波束发送的用于跟踪该终端设备的上行信号后，便针对该上行波束发送的上行信号，采用关联的下行波束发送所述下行跟踪响应消息；然后接收下一个上行波束发送的上行信号，然后针对该下一个上行波束发送的上行信号，采用关联的下行波束发送下行跟踪响应消息；以此类推，直到终端设备轮询完所有的发送波束。
例如：如图4所述，终端设备在波束B1发送上行跟踪信号(或上行参考信号)，则TRP或基站在B1方向对应的下行波束方向发送下行跟踪响应消息；终端设备在波束B2发送上行跟踪信号，则TRP或基站在B2方向对应的下行波束方向发送下行跟踪响应消息；直到完成在波束Bk方向上发送上行跟踪信号，则TRP或基站在Bk方向对应的下行波束方向发送下行跟踪响应消息。
该方式的好处是基站或TRP能够有机会快速的对上行信号的波束方向进行确认，确认了优选的波束方向后，终端设备在剩下的波束方向上对应的发送机会可不用发送上行信号，减小跟踪的开销。另外在之后的上行信号发送周期里，终端可以从上个周期中优选出来的上行波束方向开始进行上行跟踪信号的发送和波束扫描，以便更快地找到最佳波束方向。
上述各个实施例中，可以仅在部分上行波束方向对应的下行波束上发送下行跟踪响应消息，例如：在信号较优的波束方向发送，信号较差的波束方向不再发送下行跟踪响应消息。
