可以理解的是，本公开实施例描述的通信***是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。It can be understood that the communication system described in the embodiments of the present disclosure is to illustrate the technical solutions of the embodiments of the present disclosure more clearly, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. With the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.
相关技术中，在多天线技术或大规模阵列天线技术中，通常默认天线形态是固定不变的。例如在5G NR***中，主要通过模拟波束赋形和数字波束赋形来改变天线波束方向和传播特性，其改变的范围受到固定天线形态的限制。基站和终端设备之间采用波束管理过程来维持较佳或最优的发送和接收波束配对(beam pair或beam correspondence)。在初始接入时，终端设备需要先确定较佳或最优的下行波束，然后使用该波束所对应的随机接入资源发起随机接入。利用随机接入资源与下行波束之间的预先确定的对应关系，就可以建立起初始的波束配对。当无线传播环境发生变化或终端移动时、导致原有波束配对的性能变差时，可以采用波束调整来改变波束配对。当无线信道出现剧烈变化，导致无法使用波束调整来改变时，可以通过波束失败恢复(Beam Failure Recovery)过程来重新选择波束配对，由于无线传播环境的变化时对于小区内的各个终端设备都是独立发生的，因此5G NR***，终端设备需要各自独立对波束进行下行测量和上报，或是各自独立发送SRS(Sounding Reference Signal，上行探测参考信号)由基站进行测量，来进行波束调整，并且波束失败恢复过程是由终端设备独立发起的。In the related art, in the multi-antenna technology or the large-scale array antenna technology, the antenna form is generally fixed by default. For example, in the 5G NR system, the antenna beam direction and propagation characteristics are mainly changed by analog beamforming and digital beamforming, and the range of change is limited by the shape of the fixed antenna. The beam management process is used between the base station and the terminal equipment to maintain a better or optimal transmit and receive beam pairing (beam pair or beam correspondence). During initial access, the terminal device needs to first determine a better or optimal downlink beam, and then use the random access resource corresponding to the beam to initiate random access. The initial beam pairing can be established by using the predetermined corresponding relationship between the random access resource and the downlink beam. When the wireless propagation environment changes or the terminal moves, causing the performance of the original beam pairing to deteriorate, beam adjustment can be used to change the beam pairing. When the wireless channel changes drastically and the beam adjustment cannot be used to change, the beam pairing can be reselected through the beam failure recovery (Beam Failure Recovery) process. Since the wireless propagation environment changes, each terminal device in the cell is independent. Therefore, in the 5G NR system, terminal devices need to independently perform downlink measurement and report on the beam, or independently send SRS (Sounding Reference Signal, uplink sounding reference signal) to be measured by the base station for beam adjustment, and the beam fails The recovery process is independently initiated by the end device.
当天线形态发生改变时，则相应天线设备到全小区的所有终端设备的波束都可能发生改变，这种情况下如果仍采用相关技术中的手段，则一个小区覆盖范围内的大量终端设备都可能启动波束调整或波束失败恢复过程。从下行测量、判定波束失败、到终端设备上报，会存在一定的延迟，即波束失败恢复过程需要一定时间，这增加了***的传输时延。此外，由于涉及大量终端设备，会同时突发的大量信令，造成控制信道拥塞，从而影响***性能。亟需新的波束管理技术来解决可改变天线形态下的波束管理问题。When the shape of the antenna changes, the beams from the corresponding antenna device to all terminal devices in the whole cell may change. Initiate the beam adjustment or beam failure recovery process. From downlink measurement, determination of beam failure, to terminal device reporting, there will be a certain delay, that is, the beam failure recovery process takes a certain amount of time, which increases the transmission delay of the system. In addition, since a large number of terminal devices are involved, a large number of signalings will burst at the same time, causing congestion of the control channel, thereby affecting system performance. New beam management techniques are urgently needed to solve the problem of beam management under changing antenna configurations.
基于此，本公开实施例提供一种波束管理方法，以实现在天线形态发生改变，基站波束的波束状态发生改变时进行波束管理，降低传输时延，提高***性能。Based on this, an embodiment of the present disclosure provides a beam management method, so as to implement beam management when the antenna form changes and the beam state of the base station beam changes, so as to reduce transmission delay and improve system performance.
在采用多天线技术且天线形态可改变的无线通信***中。例如在5G NR***中，基站的TRP(Transmission and Reception Point，传输和接收节点)通常采用某种天线形态和相应的赋形参数，使TRP的无线信号发送和接收可覆盖或服务某一个特定的空间范围。天线单元与收发射频单元之间可以采用多种连接方式，实现模拟波束赋形和数字波束赋形的混合赋形。一个或多个TRP的服务范围形成一个小区，而模拟波束赋形通常是决定小区覆盖范围的主要因素。通常模拟波束赋形是覆盖范围较大的宽波束，一个小区与一个模拟波束对应。在毫米波等频段上，还可以使用波束赋形技术形成多个不同方向的波束，这些波束的宽度较窄，但传播距离更大。这些波束组成一个波束组，组内的波束可通过时分复用的方式轮流发送，在一个时间周期内，通过波束扫描(beam sweeping)，共同服务一个小区覆盖范围。一个下行波束通常与一个SSB(Synchronization Signal Block，同步信号块)或CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)配置相关联。当使用波束扫描时，一个TRP可以配置N个波束，终端设备也可能配置M个波束，M和N为正整数。发送波束和接收波束组成一个波束配对。显然波束配对有多种可能的组合方式，其中性能较佳或最优的波束配对被用于数据信 号的传输，可提高服务。注意这里的波束是属于TRP的波束，它与终端设备的某个波束组成性能较佳或最优的波束配对。In a wireless communication system that adopts multi-antenna technology and the shape of the antenna can be changed. For example, in the 5G NR system, the TRP (Transmission and Reception Point) of the base station usually adopts a certain antenna form and corresponding shaping parameters, so that the wireless signal transmission and reception of the TRP can cover or serve a specific spatial extent. Various connection modes can be adopted between the antenna unit and the transceiver radio frequency unit to realize hybrid forming of analog beamforming and digital beamforming. The service area of one or more TRPs forms a cell, and analog beamforming is usually the main factor in determining cell coverage. Generally, the analog beamforming is a wide beam with a large coverage area, and one cell corresponds to one analog beam. On frequency bands such as millimeter waves, beamforming technology can also be used to form multiple beams in different directions. These beams have a narrower width but a greater propagation distance. These beams form a beam group, and the beams in the group can be sent in turn by means of time division multiplexing, and in a time period, through beam sweeping (beam sweeping), they can jointly serve the coverage area of a cell. A downlink beam is usually associated with a SSB (Synchronization Signal Block, synchronization signal block) or CSI-RS (Channel State Information-Reference Signal, channel state information reference signal) configuration. When beam scanning is used, one TRP can be configured with N beams, and the terminal device may also be configured with M beams, where M and N are positive integers. The transmit beam and receive beam form a beam pair. Obviously, there are many possible combinations of beam pairing, among which the better or optimal beam pairing is used for the transmission of data signals, which can improve the service. Note that the beam here is a beam belonging to the TRP, which forms a better or optimal beam pairing with a certain beam of the terminal device.
基站周期性发送包含PSS(Primary Synchronization Signal，主同步信号)、SSS(Secondary Synchronization Signal，辅同步信号)和PBCH(Physical Broadcast Channel，物理广播信道)的SSB。不同的下行波束(一般是模拟波束)可对应不同的SSB。5G NR中SSB的发送周期可以是5,10,20,40,80或160毫秒等。如果是采用了波束扫描，那么上述周期是一个波束的发送周期。多个波束之间的发送最小间隔可以为5ms。终端设备在接入小区之前，需要检测PSS和SSS，然后通过接收和解码PBCH获取SSB编号信息。基于SSB编号与随机接入资源的对应关系，终端设备在选定小区和选定波束后，在适当的随机接入资源上向基站发起随机接入，从而建立起初始的波束配对。当随机接入过程成功、RRC(Radio Resource Control，无线资源控制)连接建立完毕后，终端设备会认为基站将会使用与选定波束相同的模拟波束来进行后续的无线信号收发。终端设备也会继续采用在随机接入过程中使用的接收波束来接收无线信号。考虑到信道互易性，同样的波束也可用于上行信号传输。The base station periodically sends SSB including PSS (Primary Synchronization Signal, primary synchronization signal), SSS (Secondary Synchronization Signal, secondary synchronization signal) and PBCH (Physical Broadcast Channel, physical broadcast channel). Different downlink beams (generally analog beams) may correspond to different SSBs. The transmission period of SSB in 5G NR can be 5, 10, 20, 40, 80 or 160 milliseconds, etc. If beam scanning is adopted, the above period is a beam sending period. The minimum transmission interval between multiple beams can be 5ms. Before the terminal device accesses the cell, it needs to detect the PSS and SSS, and then obtain the SSB number information by receiving and decoding the PBCH. Based on the corresponding relationship between the SSB number and the random access resource, the terminal device initiates random access to the base station on an appropriate random access resource after selecting a cell and a selected beam, thereby establishing an initial beam pairing. When the random access process is successful and the RRC (Radio Resource Control, radio resource control) connection is established, the terminal device will think that the base station will use the same analog beam as the selected beam for subsequent wireless signal transmission and reception. The terminal device will also continue to receive radio signals using the receive beam used in the random access procedure. Considering channel reciprocity, the same beam can also be used for uplink signal transmission.
在RRC连接态的终端设备根据基站配置的SSB或CSI-RS信息，对来自TRP的多个发送波束进行测量；并按照上报配置，将包括波束的编号以及表示波束性能的参数(例如RSRP(Reference Signal Receive Power，参考信号接收功率)或RSRQ(Reference Signal Receiving Quality，参考信号接收质量))的测量结果上报给基站。终端设备还可以对于同一个发送波束使用不同的接收波束测量参考信号的RSRP或RSRQ，以确定接收波束；其中该接收波束可以为较佳或最优的接收波束。对于上行发送，即可以基于上下行信道互易性来将下行的最优波束配对直接用于上行，还可以由终端设备发送SRS。基站通过测量SRS来选择较佳或最优的上行接收波束。当无线信号传播环境变化或终端发生移动时，终端设备上报的较佳或最优波束会发生改变，或者是通过SRS测量确定的较佳或最优波束发生改变。在此情况下，基站可以改变波束为终端设备提供服务。注意终端设备上报的较佳或最优波束可能是一个也可能是多个，取决于信道状态和***配置。基站可以在终端设备上报的较佳或最优波束中选择波束、或者结合其他因素选择波束，来为该终端设备提供服务。目前5G NR协议支持基站通过无线资源控制(RRC，Radio Resource Control)消息为终端设备配置多个波束。MAC(Media Access Control，媒体接入控制)的CE(Control Element，控制元素)可以进一步指示候选波束的子集。在PDCCH(Physical Downlink Control Channel，物理下行控制信道)传输的DCI(Downlink Control Information，下行控制信息)可以指示最终用于数据信号传输的波束。波束指示在5G NR标准中实际上是PDCCH或PDSCH(physical downlink shared channel，物理下行共享信道)与SSB或CSI-RS的对应关系，即指示PDCCH或PDSCH使用与某一SSB或CSI-RS相同的模拟波束。该对应关系用TCI(Transmission Configuration Indication)状态来表示。The terminal equipment in the RRC connection state measures multiple transmission beams from the TRP according to the SSB or CSI-RS information configured by the base station; and according to the report configuration, it will include the number of the beam and the parameters indicating the performance of the beam (such as RSRP (Reference Signal Receive Power, reference signal received power) or RSRQ (Reference Signal Receiving Quality, reference signal received quality)) measurement results are reported to the base station. The terminal device may also use different receiving beams to measure the RSRP or RSRQ of the reference signal for the same sending beam to determine the receiving beam; wherein the receiving beam may be a better or optimal receiving beam. For uplink transmission, the optimal downlink beam pairing can be directly used for uplink based on the reciprocity of the uplink and downlink channels, and the terminal device can also send the SRS. The base station selects a better or optimal uplink receiving beam by measuring the SRS. When the wireless signal propagation environment changes or the terminal moves, the preferred or optimal beam reported by the terminal device will change, or the preferred or optimal beam determined through SRS measurement will change. In this case, the base station can change the beam to serve the terminal device. Note that the preferred or optimal beam reported by the terminal device may be one or more, depending on the channel state and system configuration. The base station may select a beam from among the better or optimal beams reported by the terminal device, or select a beam in combination with other factors to provide services for the terminal device. The current 5G NR protocol supports the base station to configure multiple beams for the terminal device through the radio resource control (RRC, Radio Resource Control) message. CE (Control Element, Control Element) of MAC (Media Access Control, Media Access Control) may further indicate a subset of candidate beams. The DCI (Downlink Control Information, downlink control information) transmitted on the PDCCH (Physical Downlink Control Channel, physical downlink control channel) can indicate the beam finally used for data signal transmission. Beam indication in the 5G NR standard is actually the correspondence between PDCCH or PDSCH (physical downlink shared channel, physical downlink shared channel) and SSB or CSI-RS, that is, indicating that PDCCH or PDSCH uses the same SSB or CSI-RS Analog beams. The corresponding relationship is represented by TCI (Transmission Configuration Indication) status.
如果无线信道出现剧烈变化，导致无法使用上述波束调整方式来及时改变波束时，可以通过波束失败恢复(Beam Failure Recovery)过程来重新选择波束配对。如果SSB或CSI-RS的RSRP或RSRQ低于一个预先配置的门限值时，终端设备认为发生了一次波束失败实例。当连续出现超过某一门限值的多个波束失败实例时，终端设备就可以发起波束失败恢复过程。此时，终端设备需要重新确定出个波束配对，并通过随机接入信道向基站发起随机接入请求。由于随机接入信道资源与波束有预先约定的关系，基站可以获知终端设备选择的较佳或最优波束，从而使用该波束进行后续的通信。If the wireless channel changes drastically, making it impossible to use the above beam adjustment method to change the beam in time, you can reselect the beam pairing through the beam failure recovery (Beam Failure Recovery) process. If the RSRP or RSRQ of the SSB or CSI-RS is lower than a pre-configured threshold, the terminal device considers that a beam failure instance has occurred. When multiple beam failure instances exceeding a certain threshold occur consecutively, the terminal device can initiate a beam failure recovery process. At this time, the terminal device needs to re-determine a beam pairing, and initiate a random access request to the base station through a random access channel. Since there is a pre-agreed relationship between the random access channel resource and the beam, the base station can know the better or optimal beam selected by the terminal device, and then use the beam for subsequent communication.
而本公开实施例中，提供一种波束管理方法，在基站的天线形态发生改变时，基站波束的波束状态发生改变的情况下，能够解决采用相关技术终端设备发起波束失败恢复过程或者发送上行SRS由基站测量以进行波束调整的方法，信令开销大和传输时延大的问题，降低信令开销以及传输时延，提高***性能。However, in the embodiments of the present disclosure, a beam management method is provided. When the antenna form of the base station changes and the beam state of the base station beam changes, it can solve the problem of using a related technology terminal device to initiate a beam failure recovery process or send an uplink SRS. The method of performing beam adjustment by base station measurement has the problems of large signaling overhead and large transmission delay, reduces signaling overhead and transmission delay, and improves system performance.
请参见图2，图2是本公开实施例提供的一种波束管理方法的流程图。Please refer to FIG. 2 . FIG. 2 is a flowchart of a beam management method provided by an embodiment of the present disclosure.
如图2所示，该方法应用于终端设备，该方法可以包括但不限于如下步骤：As shown in Figure 2, the method is applied to a terminal device, and the method may include but not limited to the following steps:
S21：接收基站发送的第一指示信息；其中，第一指示信息用于指示基站波束的波束状态发生改变。S21: Receive first indication information sent by the base station; where the first indication information is used to indicate that a beam state of a beam of the base station changes.
基于上述论述可知，相关技术中，在天线形态发生改变，基站波束的波束状态发生改变时，终端设 备启动波束调整或波束失败恢复过程，一方面，终端设备启动波束调整或波束失败恢复过程需要一定时间，会增加***的传输时延，另一方面，由于基站波束的波束状态发生改变时，基站服务的小区中存在大量终端设备，会同时突发大量信令，造成控制信道拥塞，从而影响***性能。Based on the above discussion, it can be seen that in related technologies, when the antenna configuration changes and the beam state of the base station beam changes, the terminal device starts the beam adjustment or beam failure recovery process. On the one hand, the terminal device needs a certain Time will increase the transmission delay of the system. On the other hand, when the beam state of the base station beam changes, there will be a large number of terminal devices in the cell served by the base station, and a large number of signaling will burst at the same time, resulting in control channel congestion, which will affect the system. performance.
而本公开实施例中，支持基站主动向终端设备发送第一指示信息，指示基站波束的波束状态发生改变，从而无需终端设备进行下行测量，判定波束失败，再上报以发现波束失败过程。However, in the embodiments of the present disclosure, the base station is supported to actively send the first indication information to the terminal device, indicating that the beam state of the base station beam has changed, so that the terminal device does not need to perform downlink measurement, determine that the beam fails, and then report to discover the beam failure process.
可以理解的是，对于天线形态改变，基站波束的波束状态的改变，基站是可以进行预测的，基于此，本公开实施例中，支持基站主动向终端设备发送第一指示信息，指示基站波束的波束状态发生改变，以告知终端设备，无需终端设备进行下行测量，判定波束失败，再上报发现波束失败过程，能够降低传输时延，并减少信令开销。It can be understood that the base station can predict the change of the antenna form and the beam state of the base station beam. Based on this, in the embodiment of the present disclosure, the base station is supported to actively send the first indication information to the terminal device to indicate the position of the base station beam. The beam state is changed to inform the terminal equipment that it is not necessary for the terminal equipment to perform downlink measurement, determine that the beam fails, and then report the process of discovering the beam failure, which can reduce transmission delay and signaling overhead.
在一些实施例中，基站波束的波束状态发生改变是由基站的天线形态改变产生的。In some embodiments, the change of the beam state of the beam of the base station is caused by the change of the shape of the antenna of the base station.
可以理解的是，当基站的天线形态发生改变时，则相应的基站的天线设备到基站服务的小区中，全小区的所有终端设备的波束都可能发生改变。It can be understood that when the antenna form of the base station changes, the antenna equipment of the corresponding base station enters the cell served by the base station, and the beams of all terminal devices in the whole cell may change.
本公开实施例中，基站波束的波束状态发生改变是由基站的天线形态改变产生的，进一步的，基站发送给终端设备的第一指示信息，也可以指示基站的天线形态发生改变，以指示基站波束的波束状态发生改变。In the embodiment of the present disclosure, the change of the beam state of the base station beam is caused by the change of the antenna form of the base station. Further, the first indication information sent by the base station to the terminal device may also indicate the change of the antenna form of the base station to indicate that the base station The beam state of the beam changes.
可以理解的是，天线形态改变导致原模拟赋形波束状态发生改变，也可以看作是波束对应的SSB或CSI-RS的发送发生了改变，进而导致基于原有的SSB或CSI-RS进行的测量在未来会失效。同时，由TCI指示的与SSB或CSI-RS相关联的PDCCH或PDSCH发送也会发生改变，导致原有的波束配对不再是较佳或最优的。因此，该第一指示信息还可以指示当前波束发生改变，或指示当前波束即将失效(波束发生改变后实际上是原有的测量结果和/或波束配对关系失效)。当基站服务的小区配置了波束扫描时，该第一指示信息可以指示波束发生改变或失效的整体状态，并不区分单个波束的情况，还可分别指示在天线形态改变后，哪些波束发生改变或失效。It can be understood that the change of the antenna shape leads to the change of the state of the original analog shaped beam, which can also be regarded as a change in the transmission of the SSB or CSI-RS corresponding to the beam, which in turn leads to a change in the transmission based on the original SSB or CSI-RS. Measurements will be invalidated in the future. At the same time, the PDCCH or PDSCH transmission indicated by the TCI and associated with the SSB or CSI-RS will also change, resulting in that the original beam pairing is no longer better or optimal. Therefore, the first indication information may also indicate that the current beam is changed, or that the current beam is about to fail (after the beam is changed, the original measurement result and/or the beam pairing relationship is actually invalidated). When the cell served by the base station is configured with beam scanning, the first indication information can indicate the overall status of beam changes or failures, without distinguishing the situation of a single beam, and can also indicate which beams have changed or failed after the antenna form changes. invalidated.
在一些实施例中，第一指示信息用于指示基站波束的波束状态发生改变，包括以下至少之一：In some embodiments, the first indication information is used to indicate that the beam state of the base station beam changes, and includes at least one of the following:
第一指示信息用于指示基站的当前波束发生改变；The first indication information is used to indicate that the current beam of the base station has changed;
第一指示信息用于指示基站的当前波束失效；The first indication information is used to indicate that the current beam of the base station is invalid;
第一指示信息用于指示基站的当前全部波束发生改变；The first indication information is used to indicate that all current beams of the base station have changed;
第一指示信息用于指示基站的当前全部波束失效；The first indication information is used to indicate that all current beams of the base station are invalid;

在本公开实施例中，所述第一指示信息还用于指示所述终端设备进行基于基站波束对应的导频信号进行重新测量以获得测量结果。即：所述终端设备响应于根据第一指示信息确定基站波束的波束状态发生改变，重新测量基站波束对应的导频信号，以获取测量结果，并将测量结果上报至基站。其中，第一时刻可以为接收到第一指示信息的时刻或接收到第一指示信息后的任一时刻。In the embodiment of the present disclosure, the first indication information is further used to instruct the terminal device to perform re-measurement based on the pilot signal corresponding to the beam of the base station to obtain a measurement result. That is: the terminal device re-measures the pilot signal corresponding to the base station beam in response to determining that the beam state of the base station beam according to the first indication information changes to obtain a measurement result, and reports the measurement result to the base station. Wherein, the first moment may be the moment when the first indication information is received or any moment after the first indication information is received.
而本公开实施例中，支持基站主动向终端设备发送第一指示信息，指示基站波束的波束状态发生改变，从而无需终端设备进行下行测量，判定波束失败，再上报以发现波束失败过程。However, in the embodiments of the present disclosure, the base station is supported to actively send the first indication information to the terminal device, indicating that the beam state of the base station beam has changed, so that the terminal device does not need to perform downlink measurement, determine that the beam fails, and then report to discover the beam failure process.
可以理解的是，对于天线形态改变，基站波束的波束状态的改变，基站是可以进行预测的，基于此，本公开实施例中，支持基站主动向终端设备发送第一指示信息，指示基站波束的波束状态发生改变，以告知终端设备，无需终端设备进行下行测量，判定波束失败，再上报发现波束失败过程，能够降低传输时延，并减少信令开销。It can be understood that the base station can predict the change of the antenna form and the beam state of the base station beam. Based on this, in the embodiment of the present disclosure, the base station is supported to actively send the first indication information to the terminal device to indicate the position of the base station beam. The beam state is changed to inform the terminal equipment that it is not necessary for the terminal equipment to perform downlink measurement, determine that the beam fails, and then report the process of discovering the beam failure, which can reduce transmission delay and signaling overhead.
在一些实施例中，基站波束的波束状态发生改变是由基站的天线形态改变产生的。In some embodiments, the change of the beam state of the beam of the base station is caused by the change of the shape of the antenna of the base station.
可以理解的是，当基站的天线形态发生改变时，则相应的基站的天线设备到基站服务的小区中，全小区的所有终端设备的波束都可能发生改变。It can be understood that when the antenna form of the base station changes, the antenna equipment of the corresponding base station enters the cell served by the base station, and the beams of all terminal devices in the whole cell may change.
本公开实施例中，基站波束的波束状态发生改变是由基站的天线形态改变产生的，进一步的，基站发送给终端设备的第一指示信息，也可以指示基站的天线形态发生改变，以指示基站波束的波束状态发生改变。In the embodiment of the present disclosure, the change of the beam state of the base station beam is caused by the change of the antenna form of the base station. Further, the first indication information sent by the base station to the terminal device may also indicate the change of the antenna form of the base station to indicate that the base station The beam state of the beam changes.
可以理解的是，天线形态改变导致原模拟赋形波束状态发生改变，也可以看作是波束对应的SSB或CSI-RS的发送发生了改变，进而导致基于原有的SSB或CSI-RS进行的测量在未来会失效。同时，由TCI指示的与SSB或CSI-RS相关联的PDCCH或PDSCH发送也会发生改变，导致原有的波束配对不再是较佳或最优的。因此，该第一指示信息还可以指示当前波束发生改变，或指示当前波束即将失效(波束发生改变后实际上是原有的测量结果和/或波束配对关系失效)。当基站服务的小区配置了波束扫描时，该第一指示信息可以指示波束发生改变或失效的整体状态，并不区分单个波束的情况，还可分别指示在天线形态改变后，哪些波束发生改变或失效。It can be understood that the change of the antenna shape leads to the change of the state of the original analog shaped beam, which can also be regarded as a change in the transmission of the SSB or CSI-RS corresponding to the beam, which in turn leads to a change in the transmission based on the original SSB or CSI-RS. Measurements will be invalidated in the future. At the same time, the PDCCH or PDSCH transmission indicated by the TCI and associated with the SSB or CSI-RS will also change, resulting in that the original beam pairing is no longer better or optimal. Therefore, the first indication information may also indicate that the current beam is changed, or that the current beam is about to fail (after the beam is changed, the original measurement result and/or the beam pairing relationship is actually invalidated). When the cell served by the base station is configured with beam scanning, the first indication information can indicate the overall status of beam changes or failures, without distinguishing the situation of a single beam, and can also indicate which beams have changed or failed after the antenna form changes. invalidated.
