背景技术
第五代(5G)移动标准要求更高的数据传输速度、更大的连接数量和更好覆盖等改进。5G标准旨在为数万的用户中的每一个用户提供每秒几十兆比特的数据速率，一些无线通信网络，诸如5G或者后续技术演进，会支持在非常高、甚至是极高频率(EHF)带的操作，比如支撑毫米波(mmW)频带的操作，一般为1mm至10mm波长，或30至300太赫兹(GHz)。这些极高频率的操作，可以支持非常高的吞吐量。然而，在非常高或极高频率的无线通信中，高频通信可能会发生极大的传播损耗。在mmW频带，传播损耗可能比较严重。且在大量密集分布的天线单元中，会迫使终端设备考虑在模拟域进行波束赋形，即在一个特定的时刻波束指向一个方向。因此，基站需要经常通过扫掠在不同方向上聚焦的波束集合来向终端设备进行传送，但是扫掠波束集合的方式，在时间、功耗和空中资源方面具有昂贵的成本。

请参阅图2至图11，图2、图5、图9和图11为本申请实施例提供的无线通信方法的流程示意图，图3、图4、图6至图8和图10为本申请实施例提供的应用场景示意图。该方法应用于基站，该方法包括：
步骤201，对目标小区内的所有终端进行用户分组管理。
在一些实施例中，所述对目标小区内的所有终端进行用户分组管理，包括：在基站与目标小区内的所有终端建立初始波束时，根据所述目标小区内的每一终端对应的初始波束确定所述目标小区内的每一终端所在的初始用户组。
其中，目标小区为基站所管理的小区。例如，该目标小区可以为新无线(new radio，NR)小区。NR小区的主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)以及和广播信道(Physical Broadcast Channel，PBCH)组成的时频资源(Synchronization Signal Block，SSB)，不同的频段对应的同步信号块集合(SS Burst set)使用的SSB数量的上限不同，SS Burst set将在5ms窗口内以预定的方向(波束)在时域内重复，每个SS Burst set周期为20ms。
例如，如图3所示的建立初始波束的场景示意图，假设一个SS Burst set包括5个SSB，编号为RS-1～RS-5。NR小区(目标小区)采用波束扫描方式发送SSB，每个SSB波束在空间的指向都不同。在UE搜索小区阶段，UE测量一个SS Burst set中全部的SSB,并找到信号最好的SSB，这对应图3所示的P1(初始化波束选择)过程。之后通过P2(发射波束改变)过程做波束(BEAM)优化，找到一个比SSB波束更窄的波束，用于传输物理下行共享信道(Physical Downlink Shared Channel，PDSCH)/物理下行控制信道(Physical Downlink Control Channel，PDCCH)。P3过程用于FR2频段，UE也具有波束赋形能力。在基站与UE建立初始波束时，基站在一个SSB对应的时间内发射的多个优化波束使用相同的CSI参考信号资源，UE采用不同的波束尝试接收，一方面SSB和下行波束相关联，另一方面SSB还和上行随机接入时机、前导码等资源相联系。这样基站就可以通过随机接入获知UE选择的下行波束，因为一个特定的时刻波束只能指向一个方向，为不同方向的UE发送的下行数据就需要安排在不同的时刻分别进行，接收波束在某一个时刻也只能对准一个方向进行接收，从而实现基站和UE建立初始波束对。并且一个波束与一个解调参考信号(Demodulatin Reference Signal，DMRS)端口/端口组、或一个传输配置编号(Transmission Configuration Index，TCI)、或一个收发点(transmit-receive point，TRP)、或一个探测参考信号资源指示(SRS resource indicator，SRI)对应，其中，SRI用于上行数据传输。例如，不同的波束也可以通过不同的DMRS端口/端口组、或TCI、或TRP、或SRI表示。当建立好后初始波束对后，在随后的通信过程中，UE会假设网络的下行传输会一直沿用相同的空间滤波器，也就是假定网络会一直保持被SSB使用的发射波束。因此，UE会认为后续的下行传输会一直沿用接收的最佳接收波束。其中，5G NR的频率范围分别定义为不同的FR：FR1与FR2。频率范围FR1通 常表示5G Sub-6GHz(6GHz以下)频段，频率范围FR2通常表示5G毫米波频段。波束赋形BeamForming是一种构造天线辐射方向图的技术。
例如，每当有终端在基站管理的目标小区范围内出现时，会启动初始接入阶段。例如在基站和出现在目标小区内的终端A连接建立初始波束过程时，基站发送多个SSB，通过波束扫描同步信号和小区信息，这些SSB依次发送并且每个SSB都承载在不同的下行波束上，一方面SSB与下行波束相关联，另一方面还与上行随机时机、前导码等资源相联系。当终端A在基站管理的目标小区范围内出现时，会启动初始接入阶段，终端A发起随机接入请求，且终端根据基站发送的多个SSB，选择特定的下行波束(初始波束)来波束匹配和绑定，这样基站就可以通过随机接入获知终端选择的下行波束，因为一个特定的时刻波束只能指向一个方向，为不同方向的终端发送的下行数据就需要安排在不同的时刻分别进行，接收波束在某一个时刻也只能对准一个方向进行接收，从而基站和终端A建立初始波束对。根据终端A所确定的下行波束作为初始波束a，然后将终端A归属于该初始波束a的管理下，订阅到该初始波束a的用户组里并成为一员。将目标小区内的所有终端与基站建立初始波束，以根据目标小区内的每一终端对应的初始波束确定目标小区内的每一终端所在的初始用户组。
如图4所示的基站分组管理用户组的场景示意图，对一个5G基站(gNB)管理的小区里所有用户进行寻呼分组管理，分组依据为基于基站下行每一个波束管理一个用户组。
在UE与基站建立连接时，基站存储有目标小区内所有UE id的信息(IMSI，TMSI等)，当UE与基站完成初始波束的建立时，基站即知道UE在哪个波束下接收信号，即将在某个波束下接收信号的UE归入同一个用户组中。然而，因为UE的移动性、旋转性等原因，需要定期地重新评估接收端波束和发送端波束是否合适。即使UE完全静止不动，周围环境中的一些物体的移动也有可能会阻挡波束或者某些物体不再阻挡某些波束对，这就意味着必须调整波束，以降低寻呼失败的概率，才可以达到最优的服务质量。
步骤202，周期性地对所述目标小区内的所有终端更新用户分组。
在一些实施例中，所述周期性地对所述目标小区内的所有终端更新用户分组，包括：当间隔时间N达到时间门限时，接收所述目标小区内的所有终端上报的信道状态信息CSI报告；根据所述CSI报告，预测所述目标小区内的每一终端在K+N时刻对应的预估波束；根据所述预估波束确定每一终端所在的预估用户组。
如图5所示，步骤202可以通过步骤2021至步骤2023来实现，具体为：
步骤2021，当间隔时间N达到时间门限时，接收所述目标小区内的所有终端上报的信道状态信息CSI报告。
其中，当UE采用确定好的接收波束(比如初始波束)尝试接收来自基站的不同波束的信号时，基站设置信道状态信息(Channel State Information，CSI)报告框架，并将报告数量设置为“cri-RSRP”。信道状态信息获取(CSI acquisition)信息包括：参考信号接收功率(Reference Signal Received Power，RSRP)，参考信号接收质量(Reference SignalReceived Quality，RSRQ)，信道质量指示(channel-quality indicator，CQI)，秩指示(Rank Indicator，RI)，预编码矩阵指示(precoding-matrix indicator，PMI)，信号与干扰噪声比(signal to interference  plus noise ratio，SINR)等。当UE采用确定好的接收波束尝试接收来自基站的不同波束的信号时，UE会生成CSI报告，该CSI报告可以包括CSI参考信号资源指示符(CSI-RS Resource Indicator，CRI)，CSI参考信号资源指示符用于指示最强的CSI参考信号，即指示UE标识并报告最好的下行链路波束。例如，该CSI报告还可以包括从最强的CSI参考信号中测到的层1参考信号接收功率(Layer 1Reference Signal Received Power,L1-RSRP)。对于FR2频段，在这种情况下，UE可能使用一个或多个天线面板来提供波束赋形能力。CSI参考信号重复可用于生成同一个CSI参考信号波束的多个传输。UE通过测量这些重复的CSI参考信号来评估最佳的接收波束，即在基站发送重复CSI参考信号时，UE同时完成自身的波束扫描，即当UE正在发送时，UE通过评估来自基站的多个波束的CSI参考信号的质量来找出波束方向，UE评估来自多个波束中的每个波束的CSI参考信号的质量并选择最佳波束。其中，CSI参考信号传输为时间复用。
例如，基站会指示目标小区内的所有UE上报M个CSI参考信号的强度。M小于波束的总个数N。其中，由报告配置中的非零功率信道状态参考信息(non-zero-power CSI reference signal，NZP-CSI-RS)资源组定义待测量的不同波束的参考信号集合，NZP-CSI-RS资源组包括一组配置的信道状态信息参考信号(CSI-RS)或SSB，资源组的多少与UE的能力有关。BeamManagementSSB-CSI-RS参数集(该参数集属于MIMO-ParametersPerBand UE能力信息)根据波束管理支持的参考信号数量来说明UE能力，例如，在3GPP TS 38.306指定当使用FR1的工作频带时，UE必须支持至少8个CSI参考信号资源。即UE需要针对M个参考信号分别进行测量上报。
其中，基站需要设定CSI报告的上报方式，CSI报告的上报方式可以是周期上报或者触发上报，基站在开始就与目标终端达成一致。
在一些实施例中，当间隔时间达到时间门限时，接收所述目标小区内的所有终端根据第一上报指令上报的所述CSI报告，其中所述第一上报指令为在所述基站与所述目标小区内的所有终端建立初始波束时所述基站向所述目标小区内的每一终端发送的指令，所述第一上报指令用于指示所述目标小区内的每一终端在所述间隔时间达到所述时间门限时自动上报所述CSI报告。
例如，对应周期上报的方式，在基站与目标小区内的所有终端建立初始波束时，基站向目标小区内的每一终端发送的第一上报指令，该第一上报指令携带有时间门限信息，用于指示目标小区内的所有终端自动监测间隔时间，当目标小区内的每一终端监测到间隔时间达到时间门限时，目标小区内的每一终端自动上报CSI报告。
在一些实施例中，当间隔时间达到时间门限时，向所述目标小区内的所有终端发送第二上报指令，以及接收所述目标小区内的所有终端根据所述第二上报指令上报的所述CSI报告。
例如，对应触发上报的方式，当间隔时间达到时间门限时，基站向目标小区内的所有终端发送的第二上报指令，第二上报指令用于指示目标小区内的所有终端上报CSI报告，当目标小区内的每一终端接收到第二上报指令时，触发目标小区内的每一终端立即上报CSI报告。
在一些实施例中，在步骤2021之前，还包括：设定间隔时间N。其中，设定的该间隔 时间N，用于表示从建立初始波束到当前时刻的间隔时间。
在一些实施例中，所述时间门限包括以下至少一种：一个时频资源SSB；同步信号块集合SS Burst set的周期；SS Burst set周期的倍数。
步骤2022，根据所述CSI报告，预测所述目标小区内的每一终端在K+N时刻对应的预估波束。
在一些实施例中，所述CSI报告包括所述目标小区内的每一终端对应的M个波束的CSI参考信号，所述目标小区内的每一终端确定的最强波束的层1参考信号接收功率L1-RSRP，以及所述目标小区内的每一终端的剩余M-1个波束的参考信号接收功率和所述最强波束的L1-RSRP的差值。
例如，UE1上报的CSI报告包括与UE1自身匹配的M个波束对应的CSI参考信号，UE1确定的最强波束的层1参考信号接收功率L1-RSRP，以及UE1的剩余M-1个波束的参考信号接收功率和UE1的最强波束的L1-RSRP的差值。UE2对应的CSI报告包括与UE2自身匹配的M个波束对应的CSI参考信号，UE2确定的最强波束的层1参考信号接收功率L1-RSRP，以及UE2的剩余M-1个波束的参考信号接收功率和UE2的最强波束的L1-RSRP的差值。
在一些实施例中，所述根据所述CSI报告，预测所述目标小区内的每一终端在K+N时刻对应的预估波束，包括：根据所述CSI报告确定所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值；根据所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值，计算所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值；将所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值中的最大值对应的波束确定为所述目标小区内的每一终端在K+N时刻对应的预估波束。
在一些实施例中，在所述根据所述CSI报告确定所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值之后，还包括：将所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值存储至寄存器中；所述根据所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值，计算所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值，包括：根据所述寄存器中存储的所述目标小区内的每一终端对应的M个波束在K时刻和K-1时刻的RSRP值，计算所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值，其中所述K时刻和K-1时刻为所述寄存器中存储的所有时刻中与所述K+N时刻最接近的两个时刻。
在一些实施例中，根据所述CSI报告确定所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值，包括：根据所述目标小区内的每一终端对应的所述M个波束的CSI参考信号，所述目标小区内的每一终端确定的最强波束的层1参考信号接收功率L1-RSRP，以及所述目标小区内的每一终端的剩余M-1个波束的参考信号接收功率和所述最强波束的L1-RSRP的差值，确定所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值。
例如，基站指示所有的UE上报自身所测量的M个CSI波束对应的参考信号，以及UE确定的最强波束的L1-RSRP，对于剩余M-1个波束的测量，上报剩余波束的RSRP和最强波束的L1-RSRP的差值，上述上报的测量数据可以通过CSI报告进行上报。例如，基站接收到各个UE在接收确定的波束上上报的K时刻强度为最强波束L1-RSRP，以及M-1个剩余波束的RSRP和最强波束的L1-RSRP的差值，基站根据UE上报的最强波束L1-RSRP，以及M-1个剩余波束的RSRP和最强波束的L1-RSRP的差值，来确定M个波束的强度为RSRP i。其中，被确定的M个波束的强度为RSRP i可以包括多个时刻的波束强度。
其中，基站可设置寄存器，用于存储K时刻及K时刻之前(比如K-1时刻)所有的终端设备UE_ID上报的M个波束的强度为RSRP i，其中，i＝0，1，2……M-1；基站有有L个下行波束，每一个波束管理的UE组成一个组，因此有L个用户组，M>0，且M为整数。然而，因为UE的移动性、旋转性等原因，周期地重新评估发送端波束是否合适。即使UE完全静止不动，周围环境中的一些物体的移动也有可能会阻挡波束或者某些物体不再阻挡某些波束对，这就意味着必须调整波束，以降低寻呼失败的概率，才可以达到最优的服务质量。
其中，在寻呼下发时刻(K+N)时，基站(Base Station，BS)需要重新调整用于下发寻呼的波束。其中，N表示间隔时间，N最小为一个SSB，N也可以是SS Burst set的周期，N也可是SS Burst set周期的倍数。N表示从建立初始波束到当前时刻的间隔时间。
在一些实施例中，根据所述目标小区内的每一终端对应的所述M个波束在K时刻和K-1时刻的RSRP值，计算所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值，包括：计算所述目标小区内的每一终端对应的第i个波束在K时刻的RSRP值与第i个波束在K-1时刻的RSRP值之间的差值；将所述间隔时间N与所述差值相乘，得到第一计算结果；根据所述第i个波束在K时刻的RSRP值与所述第一计算结果的和，确定所述目标小区内的每一终端对应的第i个波束在K+N时刻的RSRP值；根据所述目标小区内的每一终端对应的所述第i个波束在K+N时刻的RSRP值，确定所述目标小区内的每一终端对应的所述M个波束在K+N时刻的RSRP值，其中，i＝0，1，2…M-1。
其中，在K时刻和K-1时刻，基站根据寄存器存储K时刻和K-1时刻接收的所有UE上报的M个波束的RSRP值，基站基于所有UE对应的M个波束在K时刻和K-1时刻的RSRP值，估算目标小区内的每个UE对应的M个波束在K+N时刻的RSRP值，可以表示为以下公式(1)：
RSRP i(K+N)＝RSRP i(K)+N*[RSRP i(K)-RSRP i(K-1)]      (1)；
其中，N表示间隔时间；i表示波束编号，i＝0，1，2…M-1；RSRP i(k+N)表示第i个波束在K+N时刻的RSRP值；RSRP i(K)表示第i个波束在K时刻的RSRP值；RSRP i(K-1)表示第i个波束在K-1时刻的RSRP值；RSRP i(K+N)表示第i个波束在K+N时刻的RSRP值。其中，中括号[]为取整函数。
其中，在估算目标小区内的每个UE对应的M个波束在K+N时刻的RSRP值时，可以采用每个UE对应的M个波束在K时刻和K-1时刻的RSRP值及上述公式(1)，遍历计算每个UE对应的第i个波束在K+N时刻的RSRP值。
其中，K时刻和K-1时刻为寄存器中存储的所有时刻中与K+N时刻最接近的两个时刻，其中K时刻与K+N时刻最接近，K-1时刻为K时刻之前的时刻，K-1时刻与K+N时刻之前存在K时刻。
其中，对于当前估算的某个UE在K+N时刻对应的预估波束，基于该UE对应的M个波束的RSRP的值序列为[RSRP i(K+N)] i＝0，1，2…M，该序列中取最大值max|RSRP i(K+N)|为该UE在K+N时刻预计的该UE上报的最强的波束强度,将该序列中取最大值max|RSRP i(K+N)|对应的波束确定为该UE的预估波束。若基站需向该UE发起寻呼，则基站将会发送寻呼在这个UE对应的预估波束上。也就是基站预测在K+N时刻UE将会在该预估波束覆盖的用户组内，并可以知晓UE的位置。随后可使用该预测的UE位置来定向地向UE传送寻呼信息。
步骤2023，根据所述预估波束确定每一终端所在的预估用户组。
在一些实施例中，所述根据所述预估波束确定每一终端所在的预估用户组，包括：将所述目标小区内的每一终端在K+N时刻对应的预估波束管理的用户组确定为所述目标小区内的每一终端在K+N时刻所在的预估用户组。
步骤203，根据所述用户分组发起不同组的寻呼。
在一些实施例中，所述根据所述用户分组发起不同组的寻呼，包括：通过每一终端对应的所述预估波束向每一终端所在的所述预估用户组发送寻呼信息，以发起不同组的寻呼。
例如，如图6所示，在建立初始波束时开始确定该小区有两个用户组：用户组1和用户组3。用户组1包括UE4、UE5、UE6和UE7；用户组3包括UE1、UE2和UE3。
在给定的时间内，尤其UE RRC在去激活(inactive)状态下，基站和UE无需进行波束的再次配对和波束的重新建立过程，当隔时间N达到时间门限时，基站可以根据该方法预测UE在K+N时刻时位于哪一个用户组里，并且发起寻呼。在图7或者图8中，UE1，UE6，UE7的用户分组发生改变，增加了一个用户组2，UE1，UE6，UE7从原来的用户组3和用户组1调整到用户组2，其中，可以根据SSB set的周期计算波束的调整时间。其中，(1)为向用户组1发起寻呼的波束；(2)为向用户组2发起寻呼的波束；(3)为向用户组3发起寻呼的波束。
如图7或图8所示，对一个5G基站管理的小区里所有用户进行寻呼分组管理，分组依据为基于基站下行每一个波束管理一个用户组。当基站发起寻呼时，仅对对应波束管理的用户组发起寻呼，其它波束管理的用户不发起寻呼。
在一些实施例中，当所述基站向目标终端发起寻呼时，根据所述目标小区内的每一终端在K+N时刻对应的预估波束以及每一终端所在的预估用户组，确定所述目标终端在K+N时刻对应的目标波束以及所述目标终端所在的目标用户组，其中，所述目标终端为需要寻呼的终端，所述目标终端位于所述目标小区内；通过所述目标波束向所述目标用户组发送寻呼信息，以寻呼所述目标终端。
在一些实施例中，如图9所示，步骤203可以通过步骤2031至步骤2032来实现，具体为：
步骤2031，当所述基站向目标终端发起寻呼时，根据所述目标小区内的每一终端在K+N 时刻对应的预估波束以及每一终端所在的预估用户组，确定所述目标终端在K+N时刻对应的目标波束以及所述目标终端所在的目标用户组，其中，所述目标终端为需要寻呼的终端，所述目标终端位于所述目标小区内。
其中，当核心网络想要发送下行消息或数据的时候，需要通过寻呼的方式让UE回到连接模式(RRC_CONNECTED)状态。寻呼消息属于被核心网寻呼的UE能够正确地接收基于调度的物理下行控制信道(Physical Downlink Control Channel，PDCCH)来传输的寻呼信息。
其中，当网络需要对目标终端进行寻呼时，为终端服务的核心网节点(比如移动管理实体MME)可以向跟踪区域范围内所有的接入网节点(比如，或者基站eNB、eNodeB)发起寻呼流程，此时接入网节点便可以接收核心网节点发送的寻呼消息。该寻呼消息用于寻呼目标终端。其中，该寻呼消息中可以携带需要寻呼的目标终端的目标UE身份标识(UE_ID)，该目标终端的目标UE身份标识可以包括终端标识索引值和该目标终端的国际移动用户识别码(International Mobile SubscriberIdentity，IMSI)，或需要寻呼的目标终端的终端标识索引值和临时移动用户识别码(S-TemporaryMobile Subscriber Identity，S-TMSI)，或者需要寻呼的临时移动台识别码(Temperate Mobile Station Identity，TMSI)。
在一些实施例中，步骤2031可以包括：在接收到5G核心网传输的寻呼消息时，根据所述寻呼消息中携带的需要寻呼的目标终端的目标UE身份标识，将所述目标小区内的所有终端中与所述目标UE身份标识对应的终端确定为所述目标终端；根据所述确定的目标终端在K+N时刻对应的预估波束确定为所述目标终端在K+N时刻对应的目标波束，以及根据所述确定的目标终端在K+N时刻所在的预估用户组，确定所述目标终端所在的目标用户组。
步骤2032，通过所述目标波束向所述目标用户组发送寻呼信息，以寻呼所述目标终端。
例如，其中，该寻呼消息中可以携带需要寻呼的目标终端的目标UE身份标识(UE_ID)，该目标终端的目标UE身份标识可以包括IMSI、S-TMSI)或者TMSI。
其中，基站向目标终端发起寻呼时，仅对与目标终端对应的目标波束管理的用户组发起寻呼，对其它波束管理的用户不发起寻呼。通过该方法，寻呼信息可以以定向方式被传送，而不是通过扫掠波束集合，从而实现时间、功耗、空中资源使用的节省。从整个小区来看，UE的寻呼分组管理也是动态的，即UE进入小区后不是一成不变的在某一用户组里，而是随着基站发送信号的波束不同而动态的发生变化。
在一些实施例中，通过所述目标波束向属于所述目标用户组内的所有终端发送寻呼信息，以寻呼所述目标终端，所述目标终端属于所述目标用户组。
其中，当目标用户组内的UE监听到寻呼消息DCI内部携带特定的PI-RNTI指示后，就开始解调，解码相应的PDCCH和/或PDSCH以提取自己的寻呼消息。
在一些实施例中，当所述间隔时间N未达到所述时间门限时，通过所述初始波束向所述目标终端对应的初始用户组发送寻呼信息，以寻呼所述目标终端。
例如，当间隔时间N未达到时间门限时，基站依然默认发送给目标终端的初始波束保持不变，目标终端所在的初始用户组也不变，因此，当间隔时间N未达到时间门限时，通过目标终端对应的初始波束向目标终端对应的初始用户组发送寻呼信息，以寻呼目标终端。
例如，基站可以传输32个SSB，并定期扫描不同的预定义方向(波束)，SSB覆盖的方向在某一个同步信号(Synchronization Signal，SS)突发间隔内只能是朝向一个预定义方向，下一个SS突发间隔内朝向另外一个预定义方向。SS突发集中预定义方向(波束/SSB)的最大个数与频率有关，如3ghz的“4波束”，从3ghz到6ghz的“8波束”，以及从6ghz到52.6GHz的“64波束”。
本申请实施例提供的方法，当UE进入RRC连接模式时，可以启动该波束优化过程。该波束优化过程可用于选择方向性更大、增益更高的波束。更多的定向波束可以改善链路预算，但也需要更频繁地在波束间做切换。
另外，波束信息可通过天线端口准共址(Quasi Colocation，QCL)关系来进行指示。具体地，可以在指示信息中指示一个资源(或天线端口)与另一个资源(或天线端口)具有准共址关系，来表示这两个资源(或天线端口)对应的波束具有相同的空间特征，可以采用同一个接收波束来接收。例如，指示信息可以为下行控制信息(Downlink Control Information，DCI)。其中，波束在协议中可以通过各种信号的标识来表示，例如，信道状态信息参考信号(channel state information reference signal，CSI-RS)的资源索引，同步信号广播信道块(synchronous signal/physical broadcast channel block，可以简称为SS/PBCH block，也可以简称为SSB)的索引，探测参考信号(sounding reference signal,SRS)的资源索引，跟踪参考信号(tracking reference signal,TRS)的资源索引。基站通过资源索引可以获得K+N时候发起寻呼的预估波束，并通过QCL，可使用在搜索空间中指示的一个或多个资源向UE传送下行数据。
为了更好地说明本申请实施例，请参阅如图10所示的基站与终端的交互场景示意图。基站按照下行扫描周期周期性地进行波束扫描，以发送同步信号，同步信号包括主同步信号(PSS)、辅同步信号(SSS)以及广播信道(PBCH)等，将PSS、SSS与PBCH一起作为同步信号发送，终端1和终端2通过波束扫描读取和解调同步信号后，并在初始选定的波束上向基站发送前导码，将前导码通过物理随机接入信道(Physical Random Access Channel，PRACH)时隙可配置的子集中进行发送，以完成随机接入过程。基站通过读取前导码确定终端的接收波束，从而知道终端属于哪一个波束管理之下，进而确定终端所在的用户组。基站设定一个时间门限，当间隔时间达到时间门限时，会触发终端1和终端2进行信道状态信息参考信号(channel state information reference signal，CSI-RS)上报，根据上报的结果重新估计终端1和终端2在K+N时刻分别对应的最强波束作为估计终端1和终端2分别对应的目标波束，进而确定终端1和终端2所在的用户组，在分别确定的目标波束上分别向终端1和终端2所在的用户组发起寻呼，并通过QCI(QoS class identifier)或者下行控制信息(Downlink Control Information，DCI)标识物理下行控制信道(Physical Downlink Control Channel，PDCCH)和物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输的波束和资源，以 保证后续顺利的传输。例如，该时间门限可以为以下至少一种：一个SSB；SS Burst set的周期；SS Burst set周期的倍数。
其中，对于用户组，UE所在用户组的确定以及订阅是基于用户组确定的波束以及在达到相应的时间门限条件下，即用户组的确定是基于CSI-RS测量的结果确定的，且当间隔时间达到或超过系统设定的时间门限时，会重新确定用户组的管理。通过本申请实施例所提的方法，无论用户是否移动，基站可以预估需要发送寻呼时刻，终端所在的用户群以及用户群所关联的发送波束。
例如，如图11所示，对于用户组的确定，在步骤1101中，在基站和UE连接建立初始波束过程时，基站发送多个SSB，这些SSB依次发送并且每个SSB都承载在不同的下行波束上，一方面SSB与下行波束相关联，另一方面还与上行随机时机、前导码等资源相联系。这样基站就可以通过随机接入获知终端选择的下行波束，因为一个特定的时刻波束只能指向一个方向，为不同方向的终端发送的下行数据就需要安排在不同的时刻分别进行，接收波束在某一个时刻也只能对准一个方向进行接收，从而基站和终端建立初始波束对。在步骤1102中，根据终端所确定的下行波束，即终端归属于该波束的管理下，订阅到该波束的用户组里并成为一员。在步骤1103中，判断间隔时间N是否等于时间门限；若否，则执行步骤1104；若是，则执行步骤1105。在步骤1104中，如果N不等于时间门限，基站依然默认发送给终端的波束保持不变，终端所在的用户组也不变。在步骤1105中，当N等于时间门限时，基站根据本申请实施例提出的方法重新估计每一终端K+N时刻时UE接收的最强波束。在步骤1106中，基站根据估算结果重新确定每一终端所在的用户组。在该实施例中，时间门限可以为SS Burst set的周期或者SS Burst set周期的倍数，当从建立初始波束到当前时刻的间隔时间N等于SS Burst set的周期或者SS Burst set周期的倍数时，需重新估计每一终端K+N时刻时UE接收的最强波束；当从建立初始波束到当前时刻的间隔时间N不等于SS Burst set的周期或者SS Burst set周期的倍数时，默认发送给终端的波束保持不变，
上述所有的技术方案，可以采用任意结合形成本申请的可选实施例，在此不再一一赘述。
本申请实施例通过对基站目标小区内的所有终端进行用户分组管理，并周期性地对目标小区内的所有终端更新用户分组，然后根据用户分组发起不同组的寻呼。本申请实施例对一个基站管理的小区里所有用户进行寻呼分组管理，每一个波束管理一个用户组，并周期性地对目标小区内的所有终端更新用户分组，然后根据用户分组发起不同组的寻呼，同一个寻呼，只对目标波束对应的用户组发起寻呼，而对其它波束管理的用户组不发起寻呼，进而可以缩短寻呼时间，降低能耗，以及节约成本。具体的，当间隔时间达到时间门限时，可以根据所有终端上报的CSI报告，重新预测目标小区内的每一终端在K+N时刻对应的最强波束为预估波束，预测以及每一终端所在的预估用户组，当基站向目标终端发起寻呼时，根据上述预估波束和预估用户组确定待寻呼的目标终端在K+N时刻时UE的目标波束以及目标终端所在的目标用户组，且仅对与目标终端对应的目标波束管理的目标用户组发起寻呼，对其它波束管理的用户不发起寻呼，进而可以缩短寻呼时间，降低能耗，以及节约成本。
