背景技术
无线网络技术和应用的发展已经来到第五代移动通信技术时代。第三代合作伙伴项目(the 3rd generation partnership project，3GPP)定义了第五代(5th generation，5G)移动通信系统应用场景三大方向—增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。其中eMBB将能够为每个小区提供10G比特每秒级的上下行吞吐量，为了获得这样的带宽，eMBB将使用更加广泛的频谱资源，从长期演进(long term evolution，LTE)使用的低频段扩展至高频段(例如28GHz、39GHz等)。
高频段电磁波具有高路损的特性，为了克服高频段导致的较大的传播损耗，实现更好的小区覆盖，一种基于波束赋形技术的信号传输机制被采用，以通过较大的天线增益来补偿信号传播过程中的传输损耗。
现有技术中，通过参考信号(例如同步信号块(synchronization signal and PBCH block，SSB)和/或信道状态参考信号(channel state information reference signal，CSI-RS))来维护基站与用户设备(user equipment，UE)之间的工作波束对，但是考虑到对时频资源占用和功耗的开销，实际系统中配置的参考信号不可能满足所有的场景，如UE发生快速旋转或者基站和UE中间突然有障碍物对电磁波产生了遮挡，都会出现UE与基站之间的信道的质量变差，通信性能迅速下降，影响用户的业务体验，因此当UE与基站之间的信道的质量变差，而UE当前无法测量参考信号时，即在两次参考信号的测量间隔出现通信性能下降时，如何快速恢复通信性能成为急需解决的问题。

以下简要介绍现有技术中确定网络设备和终端设备间的工作波束对的过程。其中，网络设备以gNB为例，终端设备以UE为例。
在UE接入进入连接态后，gNB通过配置的参考信号执行P2和P3过程，以实现确定gNB和UE间的工作波束对。其中，参考信号可以为SSB或CSI-RS。
在P2过程中，gNB在不同的时刻使用不同的发送波束发送参考信号，UE采用固定的接收波束对参考信号进行测量，并将测量结果上报给gNB，以便于gNB选择最优波束。示例性地，测量结果包括不同发送波束对应的参考信号接收功率(reference signal receiving power，RSRP)测量值和/或信噪比(signal noise ratio，SNR)等，通常，若UE所处小区仅包括该UE，则gNB可以基于测量结果选择L1_RSRP测量值中的最大测量值对应的发送波束作为最优波束，或者，若UE所处小区包括多个UE，gNB可以基于测量结果和UE所处小区内的其他UE的信息确定UE对应的最优波束，如图2所示。
在P3过程中，gNB在不同的时刻始终使用P2中获得的最优波束发送参考信号，UE使用不同的接收波束来测量gNB发送的参考信号，从而获得UE的最优波束。示例性地，UE使用不同的接收波束来测量gNB发送的参考信号，得到不同接收波束对应的L1_RSRP测量值，UE选择L1_RSRP测量值中的最大测量值对应的接收波束作为最优波束，如图3所示。
通过上述P2过程和P3过程，gNB和UE可以选择各自确定的最优波束作为工作波束，通过重复上述P2过程和P3过程，可以实现持续保证gNB和UE始终工作在较优的波束对。
但是，在P3过程中，gNB为UE配置周期性或者非周期性的参考信号，因此，当参考信号的周期较长时，UE无法根据检测到的信道条件的变化，快速调整到最优的工作波束上，从而导致用户的业务体验快速变差。
如图4所示，在时刻A，UE通过测量参考信号，确定工作波束为波束2。在时刻B，UE的姿态发生变化，例如UE自身旋转一定角度，但是此时没有到达参考信号发送周期，UE无法测量参考信号调整工作波束，则UE继续使用波束2作为工作波束，但是由于UE的姿态发生变化后，UE与gNB之间的信道的质量变差，因此导致通信性能迅速下降，影响用户的业务体验。在时刻C，UE通过测量参考信号确定新的工作波束为波束1，UE与gNB之间的信道的质量提升，用户的业务体验得到改善。在时刻D，在gNB和UE间闯入障碍物，该障碍物遮挡住了当前的工作波束(即波束1)，但是此时没有到达参考信号发送周期，UE无法测量参考信号调整工作波束，则UE继续使用波束1作为工作波束，UE与gNB之间的信道的质量变差，因此通信性能迅速下降，影响用户的业务体验。直到时刻E，UE才能通过测量参考信号重新调整工作波束到波束0，使UE与gNB之间的信道的质量得到提升，用户的业务体验得到改善。
因此，当UE与gNB之间的信道的质量变差，而UE当前无法测量参考信号时，即在两次参考信号的测量间隔出现通信性能下降时，由于UE无法及时调整工作波束，将导致通信性能下降，从而可能影响到用户的业务体验。
实施例1：
基于此，本申请提供一种调整波束的方法，用于解决在两次参考信号的测量间隔通信性能下降的问题，如图5所示，该方法包括：
步骤501：在终端设备使用第一波束作为工作波束时，终端设备监控第一参数。其中， 第一参数为用于描述信道质量的参数。
在一种可能的设计中，第一参数可以为以下任意一个参数：
(1)终端设备在第一时长内解析失败的下行数据包的个数；
(2)终端设备针对物理下行共享信道(physical downlink share channel，PUSCH)解调参考信号(demodulation reference signal，DMRS)测量得到的RSRP或SNR；
(3)终端设备的功率余量；
(4)在第二时长内无线链路控制(radio link control，RLC)重传次数；
(5)在第三时长内网络设备反馈接收失败信息的上行数据包的个数；
(6)在第四时长内调制编码方案(modulation and coding scheme，MCS)下降的总阶数；
(7)在第五时长内秩(Rank)下降的总层数。
其中，针对上述参数(5)，终端设备可以通过统计接收到的网络设备反馈的否定应答(negative acknowledgement，NACK)的次数获得。针对上述参数6)中的MCS和参数(7)中的Rank，终端设备可以通过调度终端设备的上行传输的物理下行控制信道(physical downlink control channel，PDCCH)获得。因此，基于获得上述参数的不同方式，上述参数中的(1)～(4)为终端设备检测通信性能得到的用于描述信道质量的参数，上述参数中的(5)～(7)为终端设备针对网络设备通知信息得到的用于描述信道质量的参数。
应理解的是，以上参数仅为举例，终端设备还可以监控其他用于描述信道质量的参数，本申请对此不作限定。
步骤502：终端设备确定第一参数满足第一预设条件，将第一波束切换至第二波束。
应理解的是，第一预设条件为用于指示信道质量恶化的预设条件，当终端设备确定第一参数满足第一预设条件时，触发波束调整。
示例性地，若第一参数为终端设备在第一时长内解析失败的下行数据包的个数，则终端设备在第一时长内解析失败的下行数据包的个数越多，表明终端设备与网络设备之间的信道的质量越差，当终端设备在第一时长内解析失败的下行数据包的个数达到第一阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为终端设备针对DMRS测量得到的RSRP，则终端设备针对DMRS测量得到的RSRP测量值越低，表明终端设备与网络设备之间的信道的质量越差，当终端设备针对DMRS测量得到的RSRP测量值低于第二阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为终端设备针对DMRS测量得到的SNR，则终端设备针对DMRS测量得到的SNR越低，表明终端设备与网络设备之间的信道的质量越差，当终端设备针对DMRS测量得到的SNR低于第三阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为终端设备的功率余量，终端设备可以向网络设备周期性上报终端设备的功率余量。终端设备的功率余量越低，表明终端设备与网络设备之间的信道的质量越差，当终端设备的功率余量低于第四阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为在第二时长内RLC重传次数，则在第二时长内RLC重传次数越高，表明终端设备与网络设备之间的信道的质量越差，当在第二时长内RLC重传次数 大于第五阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为在第三时长内网络设备反馈接收失败信息的上行数据包的个数，则在第三时长内网络设备反馈接收失败信息的上行数据包的个数越多，表明终端设备与网络设备之间的信道的质量越差，当在第三时长内网络设备反馈接收失败信息的上行数据包的个数大于第六阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为在第四时长内MCS下降的总阶数，则在第四时长内MCS下降的总阶数越大，表明终端设备与网络设备之间的信道的质量越差，当在第四时长内MCS下降的总阶数大于第七阈值时，则终端设备将第一波束切换至第二波束。
示例性地，若第一参数为在第五时长内Rank下降的总层数，则在第五时长内Rank下降的总层数越多，表明终端设备与网络设备之间的信道的质量越差，当在第五时长内Rank下降的总层数大于第八阈值时，则终端设备将第一波束切换至第二波束。
其中，终端设备可以采用但不限于以下方式确定第二波束：
方式1：在终端设备将第一波束切换至第二波束之前，终端设备选择除第一波束外最大参考信号接收功率测量值对应的波束作为第二波束。例如，终端设备基于最近一次P3过程可以得到不同接收波束对应的参考信号接收功率，假设参考信号接收功率最大值对应的波束为第一波束，则终端设备基于参考信号接收功率测量值从大到小的排序结果，选择其中排在第二位的参考信号接收功率测量值对应的波束作为第二波束。
方式2：终端设备优先选择与第一波束临近的波束作为第二波束。如图4所示，当前工作波束为波束2，终端设备优先选择波束1或波束3作为切换后的波束。
应理解的是，上述方式1和方式2仅为举例，不作为本申请的限定。
步骤503：在终端设备切换至第二波束后，终端设备确定第一参数满足第二预设条件，则终端设备使用第二波束作为工作波束。
其中，当第一参数满足第二预设条件时终端设备与网络设备之间的信道的质量优于当第一参数满足第一预设条件时终端设备与网络设备之间的信道的质量。
应理解的是，第一波束与第二波束是不同的波束，其中，第一波束的波束方向与第二波束的波束方向不同。
在一示例中，在终端设备将第一波束切换为第二波束后，终端设备继续检测该第一参数，并在切换为第二波束后，确定第一参数满足第二预设条件时，即确定信道质量改善后，将第二波束作为工作波束。
在另一示例中，在终端设备将第一波束切换为第二波束后，终端设备继续检测该第一参数，并在切换为第二波束后，确定第一参数不满足第二预设条件时，即确定信道质量没有改善或改善效果不明显，则继续调整波束，直至第一参数满足第二预设条件，或终端设备等待到达测量参考信号的时机，终端设备通过测量参考信号重新确定工作波束。例如，在切换为第二波束后，终端设备确定第一参数不满足第二预设条件，则基于参考信号接收功率测量值从大到小的排序结果，选择其中排在第三位的参考信号接收功率测量值对应的波束作为第三波束，将第二波束切换至第三波束，并重复上述过程，判断第一参数是否满足第二预设条件，若满足，则将第三波束作为工作波束，若不满足，则继续调整波束直至第一参数满足第二预设条件。若直至到达终端设备测量参考信号的时机，第一参数仍不满足第二预设条件，则终端设备通过测量参考信号确定工作波束。
在又一示例中，在终端设备将第一波束切换为第二波束后，终端设备继续检测该第一 参数，并在切换为第二波束后，终端设备确定第一参数不满足第二预设条件，但是终端设备确定信道质量有改善，则终端设备不再继续调整波束，而是等待到达终端设备测量参考信号的时机，终端设备通过测量参考信号重新确定工作波束。
例如，第一参数为在第一时长内解析失败的下行数据包的个数，在切换为第二波束后，终端设备统计一个第一时长内解析失败的下行数据包的个数是否下降，且在统计的第一时长内解析失败的下行数据包的个数是否小于第九阈值，若是，则将第二波束作为工作波束，否则，继续调整波束，直至在统计的第一时长内解析失败的下行数据包的个数小于第九阈值，或到达终端设备测量参考信号的时机，终端设备通过测量参考信号重新确定工作波束。
此外，在一种可能的设计中，终端设备确定第一参数满足第一预设条件，且第二参数满足第三预设条件，将第一波束切换至第二波束，第二参数为用于指示信道质量的参数，第一参数与第二参数不同。终端设备确定第一参数满足第二预设条件，且第二参数满足第二预设条件，则终端设备使用第二波束作为工作波束。
其中，当第一参数满足第二预设条件且第二参数满足第四预设条件时终端设备与网络设备之间的信道的质量优于当第一参数满足第一预设条件且第二参数满足第三预设条件时终端设备与网络设备之间的信道的质量。
其中，第二参数为上述涉及的参数(1)～(7)中不同于第一参数的一个参数。
应理解的是，第一预设条件和第三预设条件为用于指示信道质量恶化的预设条件，第二预设条件和第四预设条件为用于指示信道质量恢复的预设条件。
采用上述设计，终端设备可以监控多个参数，在确定存在两个及两个以上的参数满足分别对应的用于指示信道质量恶化的预设条件时，则终端设备将第一波束切换至第二波束，同时，终端设备在确定上述两个及两个以上的参数均满足分别对应的用于指示信道质量恢复的预设条件时，将第二波束作为工作波束，以避免频繁切换波束。
例如，终端设备监控到第一参数满足第一预设条件，第二参数满足第三预设条件，其中，第一参数为在第一时长内解析失败的下行数据包的个数，第二参数为终端设备的功率余量，在切换为第二波束后，终端设备统计一个第一时长内解析失败的下行数据包的个数是否下降，以及终端设备的功率余量是否提高，当终端设备确定第一参数满足第二预设条件，且第二参数满足第四预设条件，则将第二波束作为工作波束，否则，继续调整波束。
在一种可能的设计中，终端设备确定第一参数满足第一预设条件且未到达参考信号的发送时刻，将第一波束切换至第二波束。采用上述设计，终端设备可以在未到达参考信号的发送时刻时主动调整波束。
示例性地，如图6所示，在时刻A，UE通过测量参考信号，确定工作波束为波束2。在时刻B，UE的姿态发生变化，例如UE自身旋转一定角度，但是此时没有到达参考信号发送时刻，UE无法通过测量参考信号调整工作波束，UE与gNB之间的信道的质量变差，因此导致通信性能迅速下降，影响用户的业务体验。UE在确定第一参数满足第一预设条件时，将波束2调整为波束1，并在UE采用波束1后继续监控第一参数，当确定第一参数满足第二预设条件时，将波束1作为工作波束，UE与gNB之间的信道的质量恢复，用户的业务体验得到改善。在时刻C，UE通过测量参考信号确定工作波束为波束1。因此，采用上述设计，UE能够实现在未到达参考信号发送时刻时主动调整波束，使UE与gNB之间的信道的质量得到恢复，用户的业务体验得到改善。
下面结合图7说明图6中波束调整的具体流程：
S701：gNB发送SSB。
UE基于SSB完成与gNB的同步建立。
S702：UE向gNB发送物理随机接入信道(Physical Random Access Channel，PRACH)。
示例性地，UE在gNB分配的PRACH资源上随机选择一个随机接入前导码(random access preamble)发送至gNB，以通知gNB该UE想要接入gNB下的小区。
S703：gNB向UE发送随机接入响应(Random access response，RAR)。
RAR包括与UE发送的preamble对应的前导码索引(preamble index)。
S704：UE向gNB发送消息3(Message 3，Msg3)。
由于可能存储多个UE选择相同的preamble发起随机接入过程，因此即使RAR包含了UE发送的preamble对应的preamble index，也不能说明UE本次随机接入过程成功。为了解决这种可能存在的冲突问题，Msg3包括UE的特定身份识别信息，作为冲突解决标识。
S705：gNB向UE发送消息4(Message 4，Msg4)。
Msg4包括UE的身份标识。UE通过与Msg4中的UE的身份标识确定随机接入成功。若Msg4不包括UE的身份标识，则表明随机接入失败。
上述S701～S705对应初始同步和随机接入过程，通过上述过程，UE完成初始同步和随机接入。
S706：gNB向UE发送CSI-RS。
S707：UE向gNB发送CSI-RS测量结果，CSI-RS测量结果可以包括不同发送波束对应的RSRP测量值。
上述S706～S707对应P2过程，通过上述过程，gNB选择最优波束作为工作波束，具体内容可以参见上文中关于P2过程的介绍，此处不再赘述。
S708：gNB向UE发送CSI-RS。
S709：UE基于CSI-RS测量结果选择最优波束。CSI-RS测量结果包括不同接收波束对应的RSRP测量值。
上述S708～S709对应P3过程，通过上述过程，UE选择最优波束作为工作波束，具体内容可以参见上文中关于P3过程的介绍，此处不再赘述。
应理解的是，上述S701～S709为现有技术，这里仅作为示例并不作为本申请的限定。当上述S701～S709发生变化时，不影响本申请实施例的实现。
示例性地，如图6所示，UE的工作波束为波束2。
S710：UE在确定第一参数满足第一预设条件时，主动调整工作波束。
示例性地，如图6所示，UE的工作波束为从波束2切换为波束1。
S711：gNB向UE发送CSI-RS。
S712：UE向gNB发送CSI-RS测量结果。CSI-RS测量结果可以包括不同波束对对应的RSRP测量值。
示例性地，gNB采用3个发送波束分别发送CSI-RS，UE采用2个接收波束分别进行接收，因此，UE上报的CSI-RS测量结果中包括6个RSRP测量值，每个测量值对应一个波束对。
S713：gNB向UE发送DCI，该DCI包括传输配置指示(transmission configuration indicator，TCI)，TCI用于指示一个工作波束对。
示例性地，如图6所示，UE可以通过DCI中的TCI确定波束1作为工作波束。
上述S710，S711～S713均为对工作波束对维护过程。其中，S711～S713为现有技术，仅作为示例并不作为本申请的限定。当上述S711～S713发生变化时，不影响本申请实施例的实现。
因此，采用上述方法，当终端设备确定信道质量恶化时，终端设备主动调整波束，可以实现改善通信性能，提升用户的业务体验。
实施例2：
基于此，本申请提供一种调整波束的方法，用于解决在两次参考信号的测量间隔通信性能下降的问题，如图8所示，该方法包括：

应理解的是，以上参数仅为举例，网络设备还可以监控其他用于描述信道质量的参数，本申请对此不作限定。
步骤802：网络设备确定第一参数满足第一预设条件，将第一波束切换至第二波束。
应理解的是，第一预设条件为用于指示信道质量恶化的预设条件，当网络设备确定第一参数满足第一预设条件时，触发波束调整。
示例性地，若第一参数为在第三时长内解析失败的上行数据包的个数，则在第三时长内解析失败的上行数据包的个数越多，表明终端设备与网络设备之间的信道的质量越差，当网络设备在第三时长内解析失败的上行数据包的个数达到第一预设条件对应的阈值时，则网络设备将第一波束切换至第二波束。
其中，网络设备可以采用但不限于以下方式确定第二波束：
方式1：在网络设备将第一波束切换至第二波束之前，网络设备选择除第一波束外最大参考信号接收功率测量值对应的波束作为第二波束。例如，网络设备基于最近一次P2过程可以得到终端设备反馈的测量结果，该测量结果包括不同发送波束对应的参考信号接收功率，假设参考信号接收功率最大值对应的波束为第一波束，则网络设备基于参考信号接收功率测量值从大到小的排序结果，选择其中排在第二位的参考信号接收功率测量值对应的波束作为第二波束。此外，若终端设备所处小区包括多个终端设备，网络设备还可以基于测量结果和终端设备所处小区内的其他终端设备的信息确定第二波束。
方式2：网络设备优先选择与第一波束临近的波束作为第二波束。
应理解的是，上述方式1和方式2仅为举例，不作为本申请的限定。
步骤803：在网络设备切换至第二波束后，网络设备确定第一参数满足第二预设条件，则网络设备使用第二波束作为工作波束。
其中，当第一参数满足第二预设条件时终端设备与网络设备之间的信道的质量优于当第一参数满足第一预设条件时终端设备与网络设备之间的信道的质量。
在一示例中，在网络设备将第一波束切换为第二波束后，网络设备继续检测该第一参数，并在切换为第二波束后，确定第一参数满足第二预设条件时，即确定信道质量改善后，将第二波束作为工作波束。
在另一示例中，在网络设备将第一波束切换为第二波束后，网络设备继续检测该第一参数，并在切换为第二波束后，确定第一参数不满足第二预设条件时，即确定信道质量没有改善或改善效果不明显，则继续调整波束，直至第一参数满足第二预设条件，或网络设备等待到达终端设备测量参考信号的时机，网络设备通过终端设备反馈的测量结果重新确定工作波束。例如，在切换为第二波束后，网络设备确定第一参数不满足第二预设条件，则基于参考信号接收功率测量值从大到小的排序结果，选择其中排在第三位的参考信号接收功率测量值对应的波束作为第三波束，将第二波束切换至第三波束，并重复上述过程，判断第一参数是否满足第二预设条件，若满足，则将第三波束作为工作波束，若不满足，则继续调整波束直至第一参数满足第二预设条件。若直至到达终端设备测量参考信号的时机，第一参数仍不满足第二预设条件，则网络设备通过终端设备反馈的测量结果重新确定工作波束。
在又一示例中，在网络设备将第一波束切换为第二波束后，网络设备继续检测该第一参数，并在切换为第二波束后，网络设备确定第一参数不满足第二预设条件，但是网络设备确定信道质量有改善，则网络设备不再继续调整波束，而是等待到达终端设备测量参考信号的时机，网络设备通过终端设备反馈的测量结果重新确定工作波束。
例如，网络设备确定在第三时长内解析失败的上行数据包的个数达到第一预设条件对应的阈值，在切换为第二波束后，网络设备统计一个第三时长内解析失败的上行数据包的个数是否下降，且在统计的第一时长内解析失败的下行数据包的个数是否小于第二预设条件对应的阈值，若是，则将第二波束作为工作波束，否则，继续调整波束，直至在统计的第一时长内解析失败的下行数据包的个数小于第二预设条件对应的阈值，或到达网络设备测量参考信号的时机，网络设备通过终端设备反馈的测量结果重新确定工作波束。其中，第一预设条件对应的阈值大于第二预设条件对应的阈值。
此外，在一种可能的设计中，网络设备确定至少一个参数中的第一参数满足第一预设条件，且第二参数满足第三预设条件，将第一波束切换至第二波束，第二参数为用于指示信道质量的参数，第一参数与第二参数不同。网络设备确定第一参数满足第二预设条件，且第二参数满足第二参数对应的第二预设条件，则网络设备使用第二波束作为工作波束。
其中，第二参数为上述涉及的参数(1)～(7)中不同于第一参数的一个参数。
当第一参数满足第二预设条件且第二参数满足第四预设条件时终端设备与网络设备之间的信道的质量优于当第一参数满足第一预设条件且第二参数满足第三预设条件时终端设备与网络设备之间的信道的质量。
应理解的是，第一预设条件和第三预设条件为用于指示信道质量恶化的预设条件，第二预设条件和第四预设条件为用于指示信道质量恢复的预设条件。
采用上述设计，网络设备可以监控多个参数，在确定存在两个及两个以上的参数满足分别对应的用于指示信道质量恶化的预设条件时，则终端设备将第一波束切换至第二波束，同时，终端设备在确定上述两个及两个以上的参数均满足分别对应的用于指示信道质量恢 复的预设条件时，将第二波束作为工作波束，以避免频繁切换波束。
例如，网络设备监控到第一参数满足第一预设条件，第二参数满足第三预设条件，其中，第一参数为在第三时长内解析失败的上行数据包的个数，第二参数为终端设备的功率余量，在切换为第二波束后，网络设备统计一个第三时长内解析失败的上行数据包的个数是否下降，以及终端设备的功率余量是否提高，当网络设备确定第一参数满足第二预设条件，且第二参数满足第四预设条件，则将第二波束作为工作波束，否则，继续调整波束。
因此，采用上述方法，当网络设备确定信道质量恶化时，网络设备主动调整波束，可以实现改善通信性能，提升用户的业务体验。
在一种可能的设计中，网络设备确定第一参数满足第一预设条件且未到达参考信号的发送时刻，将第一波束切换至第二波束。采用上述设计，网络设备可以在未到达参考信号的发送时刻时主动调整波束。
