Abstract

本申请提供一种终端设备接入网络的方法、通信装置，用于解决现有技术中终端设备接入网络时功耗浪费大的技术问题。当有终端设备需要接入到网络时，第一网络设备先选择N个TRP进行信号测量，获得信号测量结果，然后基于信号测量结果确定分配给终端设备用于接入的M个TRP，N和M为大于零的整数，N≥M。这样，第一网络设备可以不广播小区的系统信息，而终端设备可以只对部分TRP进行信号测量，就能实现将终端设备从TRP接入网络，可以在保证通讯效率的基础上有效节省网络设备和终端设备的功耗。

Description

一种终端设备接入网络的方法、通信装置 技术领域
本申请涉及移动通信技术领域，尤其涉及一种终端设备接入网络的方法、通信装置。
背景技术
目前，终端设备接入网络的过程为：基站广播系统信息，系统信息中有基站中各个小区的小区重选参数。用户设备(user equipment，UE)测量无线信道的参考信号接收功率(reference signal received power，RSRP)和/或参考信号接收质量(reference signal receiving quality，RSRQ)，为基站下的每一个小区计算小区接收电平值和测量小区质量值，然后又从系统消息中获取其他小区重选参数和相关的小区最低接收电平要求，由此为每个小区计算小区选择接收电平值和小区选择质量值。如果某小区选择接收电平值大于同频或者异频测量的小区重选接收电平值，且该小区选择质量值大于同频或者异频测量的小区重选质量值，则把该小区当做候选小区，并将测量值为正值最大值的小区选为驻留小区。UE选择驻留小区后，开始进行随机接入流程。
上述过程中，基站需要不停地(例如按照设定的时间间隔周期性地的)发送系统信息，使得基站和UE的功耗比较大，如何降低功耗成为亟待解决的问题。

基于上述介绍的应用网络场景，下面结合附图介绍本申请实施例提供的终端设备接入网络的具体实现过程。
请参见图2，为本申请实施例中一种终端设备接入网络的方法的流程图，该方法可以应用于上述图1所示的通信系统。该方法包括：
S201、第一网络设备选择N个第一TRP进行信号测量，获得信号测量结果。
在本申请实施例中，如果将第一网络设备和第二网络设备视为一套实体产品，或者说第二网络设备被视为第一网络设备的一部分，则可以认为TRP与第一网络设备连接，或者说TRP位于第一网络设备上；如果将第一网络设备和第二网络设备视为两个独立的实体产品，则可以认为TRP通过第二网络设备与所述第一网络设备连接。
为了便于描述，在本申请实施例中，设所有的TRP数量为Q(或者说待选择的TRP的数量为Q)，则这里的Q可以有两种理解：第一种、第一网络设备和第二网络设备被视为两个独立的实体产品时，Q为第二网络设备的全部TRP的数量；第二种、第一网络设备和第二网络设备被视为一套实体产品，或者说第二网络设备被视为第一网络设备的一部分时，Q为第一网络设备的全部TRP的数量。下面，主要以第一网络设备和第二网络设备被视为两个独立的实体产品为例对本发明技术方案进行详细介绍。
第一网络设备从Q个TRP中选择N个TRP进行信号测量，Q、N为正整数，且N≤Q。
在本申请实施例中，所述信号测量可以是对所述N个第一TRP进行上行信号测量。 信号测量的类型包括RSRP测量和/或RSRQ测量。第一网络设备选择的N个第一TRP可以是与第一网络设备连接的至少一个第二网络设备上的TRP中的部分TRP，或者是与第一网络设备连接的至少一个第二网络设备上的TRP中的全部TRP，本申请实施这里不做限制。
示例性地，第一网络设备选择所述N个第一TRP的方法包括但不限于以下两种。
方式1、终端设备选择i个邻近TRP，第一网络设备从终端设备选择的所述i个邻近TRP中选择需要进行信号测量的N个第一TRP。
具体的，第一网络设备在判断出终端设备需要接入网络时，可以先向终端设备发送报告邻近配置信息，该报告邻近配置信息用以指示终端设备从l个第二TRP中选择i个邻近TRP；终端设备接收到来自第一网络设备的报告邻近配置信息后，从l个第二TRP中选择i个邻近TRP，并基于所选择的i个邻近TRP生成TRP选择信息，然后向第一网络设备发送该TRP选择信息；第一网络设备接收来自终端设备的TRP选择信息后，在终端设备选择的所述i个邻近TRP中选择N个第一TRP，然后对选择N个第一TRP进行信号测量。i、l为正整数，N≤i≤l。
一些可能的设计中，所述l个第二TRP可以是与第一网络设备连接的至少一个第二网络设备上的TRP中全部TRP，即l＝Q；另一些可能的设计中，所述l个第二TRP可以是与第一网络设备连接的至少一个第二网络设备上的TRP中部分TRP，即l<Q本申请实施这里不做限制。
一些可能的设计中，所述报告邻近配置信息可以包括以下一项或者多项：所述l个第二TRP的TRP标识、位置信息、或邻近TRP的选择规则。其中，所述位置信息即为每个第二TRP的位置信息(例如全球导航卫星系统位置信息)。
一些可能的设计中，所述TRP选择信息可以包括：选择的i个邻近TRP的TRP标识。
一些可能的设计中，所述邻近TRP的选择规则可以有多种实现方式，例如与终端设备的距离小于阈值的TRP，或者是所述l个第二TRP中距离终端设备的最近和次近的TRP，等等，本申请实施例这里不做限制。所述的阈值可以为100米、200米等，当然也可以是其他值，本领域技术人员可以根据实际情况进行选择，本申请实施例这里不做限制。
这样，第一网络设备可以是基于预设规则在所述i个邻近TRP中选择N个第一TRP。示例性地，第一网络设备根据以下规则中的一种或多种选取所述N个第一TRP：1)、选择与终端设备的距离不超过(即小于或者等于)阈值的TRP，例如选择与终端设备的距离不超过100米的TRP；2)、选择负载不超过阈值的TRP(其中所述负载可以用已接入的终端设备数量表示，即可选择已接入的终端设备数量小于或者等于预设数量的TRP，例如选择已接入的终端设备数量小于或者等于100个的TRP)；3)、选择在白名单中的TRP，其中所述白名单中的TRP均为允许所述终端设备接入的TRP；4)选择不在黑名单中的TRP，其中所述黑名单中的TRP均为不允许所述终端设备接入的TRP。
方式2、终端设备向第一网络设备上报自身的位置信息，第一网络设备结合终端设备的位置信息，选择需要进行信号测量的N个第一TRP。
在不同的实施方式中，所述终端设备向第一网络设备上报位置信息，可以是由终端设备自身主动触发，也可以是由第一网络设备触发。
以终端设备自身主动触发上报位置信息为例，当终端设备需要接入网络时，可以先向第一网络设备上报位置信息，例如：全球导航卫星系统位置信息。
以第一网络设备触发终端设备上报位置信息为例，第一网络设备在判断出UE需要接 入网络时，可以先向终端设备发送定位上报配置信息，用以指示终端设备上报位置信息，所述定位上报配置信息包括以下几种信元(information element，IE)中的至少一种：定位上报的周期、每次定位上报的持续时间、定位上报的触发事件；终端设备在收到该定位上报配置信息后，确定自身的位置信息(例如全球导航卫星系统位置信息)，将自身的位置信息上报给第一网络设备；第一网络设备在收到终端设备上报的位置信息后，按照预设规则在与第一网络设备相连的第二网络设备上的TRP中选择N个第一TRP。
一些可能的设计中，第一网络设备可以根据以下规则中的一种或多种选取所述N个第一TRP：1)、选择与终端设备的距离不超过(即小于或者等于)阈值的TRP，例如选择与终端设备的距离不超过100米的TRP；2)、选择负载不超过阈值的TRP(例如，选择已接入的终端设备数量小于或者等于100个的TRP)；3)、选择在白名单中的TRP，其中所述白名单中的TRP均为允许所述终端设备接入的TRP；4)选择不在黑名单中的TRP，其中所述黑名单中的TRP均为不允许所述终端设备接入的TRP。
进一步的，第一网络设备在选择N个第一TRP之后，对所选择的N个第一TRP进行信号测量，可以为：第一网络设备向终端设备发送探测参考信号(sounding reference signal，SRS)配置信息，指示终端设备发送SRS；第一网络设备向所述N个第一TRP所在的第二网络设备发送信令，指示这些第二网络设备打开接收机，使得第二网络设备上的TRP能够接收SRS；终端设备向第一网络设备选择的N个第一TRP发送SRS；第二网络设备对所述N个第一TRP接收的SRS执行信号测量，将每个第一TRP对应的信号测量结果上报给第一网络设备。其中，每个第一TRP对应的信号测量结果用于指示该第一TRP中的信道状态。
S202、所述第一网络设备基于所述信号测量结果确定分配给终端设备用于接入的M个TRP，M为正整数，N≥M。
具体的，第一网络设备根据所述N个第一TRP中各个第一TRP对应信号测量结果确定分配给终端设备用于接入的M个TRP。然后，所述终端设备从第一网络设备分配的所述M个TRP发起随机接入流程，实现接入网络。可选的，结合上述方式1中第一网络设备选择所述N个第一TRP的方法，M还应满足：i≥M。
在本申请实施例中，当有终端设备需要接入到网络时，第一网络设备为终端设备选择合适的TRP，并对选择的TRP启动信号测量，然后基于信号测量结果确定分配给终端设备用于接入的TRP，从而把终端设备从分配的这些TRP中接入到网络。在该方案中，对于网络设备来说，可以不用广播小区的系统信息，因此大大节省了网络设备的功耗；对于终端设备来说，如果选择的TRP不是与第一网络设备连接的全部第二网络设备上的TRP，则不需要对所有TRP都进行信号测量(也即不需要对所有小区都进行信号测量)，因此还可以有效节省终端设备的功耗。
为了更好地理解本申请实施例技术方案，下面通过两个具体的示例对本申请实施例进行进一步的示例说明。
示例1
参见图3，为本申请实施例提供的另一种终端设备接入网络的方法的流程图，该方法可以应用于上述图1所示的通信系统。
S301、第一网络设备向终端设备发送报告邻近配置信息，用于指示终端设备选取与该终端设备邻近的TRP。
示例性的，所述报告邻近配置信息可以包含如下信息：
1)、至少一个TRP身份标识(Identity，ID)，其中一个TRP ID唯一标识一个TRP。可选的，当某个TRP只指示一个小区时，该TRP的TRP ID可以是该TRP指示的小区的标识，例如：全球小区识别码(cell global identifier，CGI)。所述CGI可以是NR小区全球标识(NR cell global identifier，NCGI)，或演进型通用陆地无线接入(evolved universal terrestrial radio access，E-UTRA)小区全球标识(E-UTRAN cell global identifier，ECGI)。为了便于区分，这里将报告邻近配置信息中的TRP称为第二TRP。第二TRP可以理解为该报告邻近配置信息所指示的TRP。
2)、第二TRP的位置信息。可选的，位置信息可以是全球定位系统(global positioning system，GPS)信息、北斗卫星导航系统(beidou navigation satellite system，BDS)信息、全球导航卫星系统(global navigation satellite system，GNSS)位置信息等，本申请实施例不做限制。
所述报告邻近配置还可以进一步包含有触发终端设备选取邻近TRP的事件(event)。例如：当终端设备和某个第二TRP的距离小于预设距离时，终端设备选取该第二TRP为邻近TRP。
应理解，第一网络设备通过第二网络设备间接地将报告邻近配置信息发送给终端设备。如图3所示，第一网络设备101先将报告邻近配置信息发送给第二网络设备102，第二网络设备102在接收到报告邻近配置信息后，再将报告邻近配置信息发送给终端设备。
S302、终端设备接收邻近配置信息，根据接收到的报告邻近配置信息，选取至少一个邻近TRP。
例如，终端设备计算自身和各个第二TRP之间的距离，比如可以按照距离的远近，选取一个或多个TRP。
S303、终端设备将选取的至少一个邻近TRP的信息上报给第一网络设备。
应理解，终端设备通过第二网络设备间接地将选取的至少一个邻近TRP的信息上报给第一网络设备。如图3所示，终端设备先将选取的至少一个邻近TRP的信息发送给第二网络设备102，第二网络设备102在接收到选取的至少一个邻近TRP的信息后，再将选取的至少一个邻近TRP的信息发送给第一网络设备101。
S304、第一网络设备接收终端设备选取的至少一个邻近TRP的信息，根据终端设备选取的至少一个邻近TRP，决定需要进行信号测量的第二网络设备。
具体的，第一网络设备在确定终端设备选取的至少一个邻近TRP后，结合TRP选取策略，从至少一个邻近TRP选择N个TRP作为第一TRP，确定选取出的N个第一TRP所在的第二网络设备需要进行RSRP测量和/或RSRQ测量。所选取的N个第一TRP所在的第二网络设备可以为一个，即所选取的N个第一TRP位于同一个第二网络设备；或者，所选取的一个或多个TRP所在的第二网络设备可以为多个，即所选取的N个第一TRP位于不同的第二网络设备。图3中以第一网络设备101选择了第二网络设备103为需要进行信号测量为例。其中，所述TRP选取策略可以包括：选择负载满足阈值的TRP、选择允许所述终端设备接入的TRP等。
决策完成后，第一网络设备给终端设备发送SRS配置信息，给确定出的第二网络设备发送信令，即图3中的步骤S305、S306。
S305、第一网络设备向终端设备发送SRS配置信息。
示例性的，SRS配置信息可以包括：SRS传输周期(duration)，SRS传输的频域位置(frequency domain position，FDP)，SRS传输的天线端口(antenna port，AP)等。
应理解，第一网络设备通过第二网络设备间接地向终端设备发送SRS配置信息。如图3所示，第一网络设备101先将SRS配置信息发送给第二网络设备102，第二网络设备102在接收到SRS配置信息后，再将SRS配置信息发送给终端设备。
S306、第一网络设备向需要进行信号测量的第二网络设备发送信令，指示该第二网络设备打开接收机，以便进行RSRP测量和/或RSRQ测量。
S307、终端设备接收SRS配置信息，根据SRS配置信息向第一网络设备所指示的第二网络设备中的N个第一TRP发送SRS。
S308、第二网络设备对所述N个第一TRP接收的SRS执行信号测量，获得每个第一TRP对应的信号测量结果(RSRP和/或RSRQ)，并将该信号测量结果报告给第一网络设备。其中，每个第一TRP对应的信号测量结果用于指示该第一TRP的信号状态。
S309、第一网络设备接收各个第二网络设备上报的信号测量结果，根据各个第二网络设备上报的信号测量结果，确定分配给终端设备用于接入网络的M个TRP。所述第一网络设备确定分配给终端设备用于接入网络的TRP，为上述步骤S304中第一网络设备选取的一个或多个第一TRP中的部分或全部TRP。
具体的，终端设备基于各个第二网络设备上报的信号测量结果，评估各TRP(或者说各小区)的信道状态，从而将瞬时信道状态好的资源块分配给终端设备的传输(基于信道相关的调度)，当然，信号测量结果还可以用于选择不同的传输参数，如允许终端设备传输的瞬时数据速率，本申请实施例对用于终端设备接入网络的TRP的分配方式不做具体限制。
在上述方案中，当终端设备需要接入网络时，首先由终端设备基于第一网络设备发送的报告邻近配置信息选择一个或多个和自身邻近的TRP，然后由第一网络设备从终端设备选择的邻近TRP中选取需要进行信号测量的TRP，然后对选取的这些TRP进行信号测量，最终基于信号测量结果确定出分配给终端设备用于接入网络的一个或者多个TRP。在该方案中，网络设备可以不广播小区的系统信息，而终端设备可以不对所有TRP都进行RSRP和/或RSRQ测量，因此可以有效节省网络设备和终端设备的功耗。并且，终端设备和网络设备都参与了需要进行信号测量的TRP的决策，可以提高通信系统的灵活性。
示例2
参见图4，为本申请实施例提供的另一种终端设备接入网络的方法的流程图，该方法可以应用于上述图1所示的通信系统。
S401、第一网络设备向终端设备发送定位上报配置，用于指示终端设备上报位置信息。
所述定位上报配置包括但不限于如下信息：1)、定位上报间隔，用于指示终端设备上报位置信息的时间间隔，例如每隔60秒上报一次位置信息；2)、定位上报持续时间，用于指示终端设备每一次上报位置信息的持续时间，例如，每次定位上报持续4秒时长；3)、定位上报触发事件，用于指示终端设备上报位置信息的触发事件，例如当终端设备检测到当前接入的TRP的RSRP小于第一设定阈值和/或RSRQ小于第二设定阈值时，终端设备开始上报自身位置信息。
应理解，第一网络设备通过第二网络设备间接地向终端设备发送定位上报配置。如图4所示，第一网络设备101先将定位上报配置发送给第二网络设备102，第二网络设备102 在接收到定位上报配置后，再将定位上报配置发送给终端设备。
S402、终端设备接收定位上报配置，并根据第一网络设备发送的定位上报配置，进行位置上报。例如，终端设备根据定位上报间隔上报自身的GPS信息、BDS信息或GNSS位置信息等。
应理解，终端设备通过第二网络设备间接地向第一网络设备上报位置信息。如图4所示，终端设备先将自身的位置信息上报给第二网络设备102，第二网络设备102在接收到位置信息后，再将位置信息发送给第一网络设备101。
S403、第一网络设备接收终端设备的位置信息，并根据终端设备的位置信息，结合TRP选取策略，选取第二网络设备，并对选取的所述第二网络设备进行RSRP测量和/或RSRQ测量。
具体的，第一网络设备可以在Q个TRP(第二网络设备的全部TRP)中选择N个TRP作为第一TRP，并确定选取出的所述N个第一TRP所在的第二网络设备需要进行RSRP测量和/或RSRQ测量。例如：选取与终端设备的距离不超过预设距离、负载满足阈值且准许所述终端设备接入的TRP所在的第二网络设备。决策完成后，执行S404～S408。
S404、第一网络设备给终端设备发送SRS配置信息。
应理解，第一网络设备通过第二网络设备间接地向终端设备发送SRS配置信息。如图4所示，第一网络设备101先将SRS配置信息发送给第二网络设备102，第二网络设备102在接收到SRS配置信息后，再将SRS配置信息发送给终端设备。
S405、第一网络设备向需要进行信号测量的第二网络设备(图4中以第二网络设备103为例)发送信令，指示该第二网络设备打开接收机，以便进行RSRP测量和/或RSRQ测量。
S406、终端设备接收来自第一网络设备的SRS配置信息，并根据SRS配置信息向第二网络设备中所述N个第一TRP发送SRS。
S407、第二网络设备对所述N个第一TRP接收的SRS执行信号测量，获得每个第一TRP对应的信号测量结果(RSRP和/或RSRQ)，并将该信号测量结果报告给第一网络设备。
S408、第一网络设备接收来自第二网络设备的信号测量结果，并根据各个第二网络设备上报的信号测量结果，确定分配给终端设备用于接入网络的M个TRP。所述第一网络设备确定分配给终端设备用于接入网络的TRP，为上述步骤S403中第一网络设备选取出的所述N个第一TRP中的部分或全部TRP。
上述步骤S404～S408的具体实现方式可以参考上述示例1中步骤S305～S309中对应步骤的具体实现方式，此处不再赘述。
在上述方案中，当终端设备需要接入网络时，终端设备基于第一网络设备发送报告定位配置向第一网络设备上报自身的位置信息，然后由第一网络设备根据终端设备的位置信息结合TRP选取策略，决定对哪些第二网络设备进行RSRP测量和/或RSRQ测量，最终第一网络设备根据各个第二网络设备的信号测量结果确定出分配给终端设备用于接入网络的一个或者多个TRP。在该方案中，网络设备可以不广播小区的系统信息，而终端设备可以不对所有TRP都进行RSRP测量和/或RSRQ测量，因此可以有效节省网络设备和终端设备的功耗。另外，需要进行信号测量的TRP由第一网络设备统一决策，可以提高决策的效率。
以上实施例是以第一网络设备和第二网络设备为两个独立的实体产品为例对本发明技术方案进行介绍。在实际应用中，也可以将第一网络设备和第二网络设备从整体上被视 为一套实体产品。下面以第一网络设备和第二网络设备从产品的角度被视为一套实体产品为例，结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。
请参见图5，为本申请另一实施例中终端设备接入网络的方法的流程图。该方法包括：
S501、基站选择N个第一TRP进行信号测量，获得信号测量结果。
类似的，所述信号测量包括RSRP测量和/或RSRQ测量。第一网络设备选择的N个第一TRP可以是所述基站中部分TRP或全部TRP，这里不做具体限制。
类似的，基站选择所述N个第一TRP的方法包括但不限于以下两种：
方式1、终端设备先选择i个邻近TRP，基站从终端设备选择的所述i个邻近TRP中选择需要进行信号测量的TRP(即所述N个第一TRP)。这里的具体实现方式可以参照上述步骤S201中方式1的具体实施方式，不再赘述。
方式2、终端设备向基站上报自身的位置信息，基站结合终端设备的位置信息，选择需要进行信号测量的一个或者多个第一TRP。这里具体实现方式可以参照上述步骤S201中方式2的具体实施方式，不再赘述。
基站在选择N个第一TRP之后，对选择N个第一TRP进行信号测量：终端设备向所述一个或多个TRP发送SRS；基站打开所述N个第一TRP对应的接收机，使得所述一个或多个第一TR能够接收SRS；基站对所述N个第一TRP接收的SRS执行信号测量，获得每个第一TRP对应的测量结果。
S502、所述基站基于所述信号测量结果确定分配给终端设备用于接入的M个TRP。
步骤S502具体实现方式可以参考上述实施例中第一网络设备基于信号测量结果确定分配给终端设备用于接入的M个TRP的具体实现方式，此处不再赘述。
在本申请实施例中，当有终端设备需要接入到网络时，基站为终端设备选择合适的TRP，并对选择的TRP启动信号测量，从而把终端设备从选择的这些TRP中接入到网络。对于基站来说，可以不用广播小区的系统信息，因此大大节省了基站的功耗；对于终端设备来说，如果选择的TRP不是基站中的全部TRP，则不需要对所有TRP都进行信号测量(即不需要对所有小区都进行信号测量)，因此还可以有效节省终端设备的功耗。
上述各实施例可以相互结合以实现不同的技术效果。
