如图1所示，本公开实施例提供的一种波束管理的方法可应用于无线通信系统100，该无线通信系统可以包括用户设备101和网络设备102。其中，用户设备101被配置为支持载波聚合，并可连接至网络设备102的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景，也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th- Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示用户设备101可以是终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该用户设备101可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。
其中，用户设备101可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备102具体可包括基站(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如，网络设备102包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA系统中的节点B(node B，NB)、CRAN系统下的无线控制器、基站控制器(basestation controller，BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
相关技术中，对于无线资源控制(Radio Resource Control，RRC)连接态(CONNECTED)的用户设备101，可以根据下行信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)进行波束跟踪和波束精调，从而在上行发送时使用更加精细合适的波束。但在初始接入过程中，用户设备101未被配置CSI-RS资源，因此只能根据同步信号块(Synchronization Signal Block，SSB)进行波束选择，而无法进行波束精调。
基于这一现状，在初始接入过程中，用户设备101一般需要使用同一发送波束发送数据，如使用msg1的发送波束发送msg3。由于毫米波频段信道的变化很快，如果用户设备101继续使用msg1的发送波束发送msg3，可能会导致数据发送失败，从而导致用户设备101不断的重新发起初始接入。
本公开实施例提供了一种波束管理的方法，图2是根据一示例性实施例示出的一种波束管理的方法的流程图，如图2所示，该方法包括步骤S201～S203，具体的：
步骤S201，在初始接入阶段，网络设备102向用户设备101发送至少一次参考信号。
在一些可能的实施方式中，网络设备102可以是按照设定的发送周期T，在不同的时域位置分别发送参考信号(Reference Signal，RS)。
在一些可能的实施方式中，参考信号可以是同步信号块(Synchronization Signal Block，SSB)，或者信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)。
例如，在初始接入阶段，网络设备102为用户设备101配置SSB资源，并按设定的周期广播SSB。
步骤S202，用户设备101接收网络设备102发送的参考信号，并基于接收的参考信号执行测量。
在一些可能的实施方式中，在初始接入过程中，用户设备101处于RRC空闲态(IDLE)，或者RRC非激活态(INACTIVE)。
在一些可能的实施方式中，用户设备101在多个时域位置分别接收网络设备102发送的参考信号。
在一些可能的实施方式中，用户设备101在每次接收到参考信号，可以测量所接收参考信号的接收信号强度指示(Received Signal Strength Indication，RSSI)、参考信号接收功率(Reference Signal Received Power，RSRP)或者参考信号接收质量(Reference Signal Received Quality，RSRQ)，从而获得每次测量参考信号对应的测量结果。
步骤S203，用户设备101根据至少一次参考信号的测量结果以及波束互易性，确定上行发送波束。
在一些可能的实施方式中，用户设备101确定上行发送波束，可以包括以下两个方面：
确定或选取上行发送波束，以及确定或调整上行发送波束的波束参数(也即调整该上行发送波束)。其中，波束参数包括波束方向和/或波束宽度。
在一些可能的实施方式中，用户设备101为支持波束互易性(beam correspondence)的终端。
在一些可能的实施方式中，支持波束互易性的用户设备101，可以根据下行接收波束来确定自己的上行发送波束，或者，根据上行发送波束来确定自己的下行接收波束。
在一示例中，若下行接收波束A是接收下行信号的较佳/最佳选择，用户设备101基于波束互易性确定下行接收波束A对应的上行发送波束A’也是较佳/最佳的上行发送波束。
在一些可能的实施方式中，用户设备101可以在测量结果满足一定条件时，选取或确定此时参考信号对应的下行接收波束。进而基于波束互易性，确定下行接收波束对应的上行发送波束。
在一些可能的实施方式中，用户设备101可以接收网络设备102发送的指示信息，该 指示信息用于指示参考信号与UE下行接收波束的对应关系。
在一示例中，网络设备102发送参考信号X时，用户设备101根据指示信息可以获知参考信号X对应的下行接收波束A，因此采用下行接收波束A接收参考信号X。基于波束互易性，可以确定下行接收波束A对应的上行发送波束A’。
在一些可能的实施方式中，在确定上行发送波束后，用户设备101可以结合其余的测量结果，确定该上行发送波束的波束参数，即对上行发送波束进行调整，以更好的发送数据。
本公开实施例中，用户设备101在初始接入阶段接收网络设备102发送的参考信号，并进行多次参考信号的测量。用户设备101基于波束互易性并结合各次参考信号的测量结果，能够合理的选取或调整上行发送波束，以保证采用合适的上行发送波束发送信息，提升初始接入过程的成功率，从而避免用户设备101不断发起初始接入。
本公开实施例提供了一种波束管理的方法，该方法被用户设备101执行。图3是根据一示例性实施例示出的一种波束管理的方法的流程图，如图3所示，该方法包括步骤S301～S302，具体的：
步骤S301，在初始接入阶段，用户设备101接收网络设备102发送的至少一次参考信号。
在一些可能的实施方式中，初始接入可由用户设备101发起。
例如，初始接入阶段包括随机接入(Random Access，RA)过程，在RA过程中，用户设备101和网络设备102会进行信令交互。如2步随机接入过程中，用户设备101会向网络设备发送msgA，并接收网络设备102发送的msgB。再如4步随机接入过程中，用户设备101会向网络设备102发送msg1和msg3，并接收网络设备102发送的msg2和msg4。
在一些可能的实施方式中，在初始接入过程中，用户设备101处于RRC IDLE态，或者RRC INACTIVE态。
在一些可能的实施方式中，网络设备102可以是按照设定的发送周期在不同的时域位置分别发送参考信号。用户设备101在测量场景下，可以在多个时域位置分别接收参考信号，即多次接收参考信号。
在一些可能的实施方式中，用户设备101在每次接收到参考信号，可以测量所接收参考信号的RSSI、RSRP或者RSRQ，从而获得每次测量参考信号对应的测量结果。
步骤S302，用户设备101根据至少一次参考信号的测量结果以及波束互易性，确定上行发送波束。

该实施方式中可以参见前述CG-SDT场景的后续数据发送的实施方式，此处不再赘述。
在一些可能的实施方式中，参考信号为以下中的一项：
第二SSB；
与第二SSB具有准共址关系的CSI-RS。
本公开实施例中，CG-SDT场景下，用户设备101可以通过多次测量进行波束调整，选取合适的上行发送波束发送数据，以便于可以提高网络设备102接收数据的成功率，避免不断重现开始初始接入。
为便于描述本公开实施例，以下列举一些具体示例：
在第一种实施例中，可通过多次测量参考信号，调整上行发送波束的波束方向和/或波束宽度。
示例一：non-SDT或者RA-SDT场景
支持波束互易性的用户设备101测量参考信号，在测量到满足第一门限值的第一SSB时，可基于该第一SSB对应的下行接收波束以及波束互易性，确定上行发送波束。该上行发送波束可用于发送msg1。
网络设备102在PRACH资源上检测到Preamble时，就可以用其关联的SSB的发送波束发送RAR。
当用户设备101接收到RAR后，用户设备101可以再次测量第一SSB或者与第一 SSB具有QCL-D关系的CSI-RS，根据该次测量结果调整上行发送波束的波束方向和/或波束宽度，调整后的波束用于发送msg3，以提高msg3发送成功率。
示例二：non-SDT或者RA-SDT场景中后续数据的发送
对于后续数据的发送，用户设备101可以采用与msg3相同的上行发送波束(即波束参数相同)发送后续数据。网络设备102同样使用与接收msg3波束相同的波束，接收后续数据。
或者，对于后续数据的发送，在后续数据发送之前，用户设备101再次测量第一SSB或者与第一SSB具有QCL-D关系的CSI-RS，根据该次测量结果调整上行发送波束的波束方向和/或波束宽度，调整后的波束用于发送后续数据。或者，在该次测量结果满足第一门限值时，再次确定上行发送波束，以发送后续数据。
示例三：CG-SDT场景
支持波束互易性的用户设备101在发送CG-SDT之前测量参考信号，在测量到满足第二门限值的第二SSB或与第二SSB具有QCL-D关系的CSI-RS时，可基于该第二SSB对应的下行接收波束以及波束互易性，确定上行发送波束，以发送CG-SDT。
其中，当参考信号是CSI-RS时，还可以结合测量结果对上行发送波束进行精调。当参考信号是第二SSB时，可以通过多次测量调整上行发送波束的波束方向和/或波束宽度。调整后的波束发送CG-SDT。
在CG-SDT的后续数据发送阶段，用户设备101可以采用与发送CG-SDT相同的波束发送后续数据，也可以再次测量第二SSB或与第二SSB具有QCL-D关系的CSI-RS，根据测量结果对上行发送波束进行调整。
在第二种实施例中，根据DRX调整上行发送波束的波束方向和/或波束宽度。
示例一：non-SDT或者RA-SDT场景
在被配置DRX的场景中，用户设备101在发起初始接入过程中会继续监听寻呼，因此用户设备101在监听寻呼时进行参考信号如第一SSB或CSI-RS的测量。
当用户设备101在发送msg3之前且监听寻呼期间，测量获得第一SSB或CSI-RS的测量结果，满足第一门限时可确定上行发送波束。结合再次测量结果可以对上行发送波束进行调整，以调整后的波束发送msg3，提高msg3发送成功率。
示例二：non-SDT或者RA-SDT场景中后续数据的发送
对于后续数据的发送，用户设备101同样可以在监听寻呼期间测量第一SSB或CSI-RS，结合测量结果调整上行发送波束的波束宽度和/或波束方向，以发送后续数据。
示例三：CG-SDT场景
在发送CG-SDT时，用户设备101可以在监听寻呼期间测量第二SSB或与第二SSB具有QCL-D关系的CSI-RS。根据测量结果确定上行发送波束，或者调整上行发送波束的波束宽度和/或波束方向，以提高发送CG-SDT的成功率。
在CG-SDT的后续数据发送阶段，用户设备101可以采用与发送CG-SDT相同的波束 发送后续数据，也可以再次在寻呼期间测量第二SSB或与第二SSB具有QCL-D关系的CSI-RS，根据测量结果对上行发送波束进行调整。
