Abstract

Disclosed in the present application are a beam searching method and apparatus. In the method, after determining a beam or antenna panel indication information, a terminal may use moment M as the start to search for a beam indicated by beam indication information, instead of using transmission moment N of a signal or channel as the start search moment of the beam. The moment M is a moment after a determination moment of the beam or antenna panel indication information and before the transmission moment N. Hence, in the present application, a terminal can implement beam searching in advance, thereby helping to avoid problems such as incomplete reception or reception failure, which is caused by a beam not being well processed at transmission moment N of a signal or channel.

Above 6GHz. The introduction of high frequency can achieve larger bandwidth and higher transmission rate. Due to the high frequency, the signal will be severely fading during the spatial propagation process. Therefore, the future communication system will use beamforming technology to obtain good directional gain, so as to improve the directional power in the transmitting direction, improve the signal-to-interference noise ratio at the receiving end, and then Improve system performance.

目前，波束管理框架包括波束训练、波束测量和上报、各信号或信道波束指示等。其中，终端设备根据信号或信道波束指示查找波束的时间是在信号或信道发送时刻去查找的，这样，对于不同能力的终端，由于波束查找、波束准备和切换均需要时间，这些处理时间会导致部分信号或信道接收不完整，或者无法接收，导致性能下降。At present, the beam management framework includes beam training, beam measurement and reporting, individual signal or channel beam indication, etc. Among them, the time for the terminal equipment to search for the beam according to the signal or channel beam indication is at the time of signal or channel transmission.

其次，对本申请实施例涉及的相关概念进行简单的介绍。Next, the related concepts involved in the embodiments of the present application are briefly introduced.

1、波束管理1. Beam management

5G以及未来的通信***引入高频频段(通常认为6G以上)，比如28GHz、39GHz或60GHz频段，来实现更大带宽、更高传输速率的需求。由于频率较高，信号在空间传播过程中会发生严重衰落。因此，5G以及未来的通信***采用波束赋形(beamforming，BF)技术获得良好的定向性增益，以提高发射方向定向功率，改善接收端信干噪比(Signal to Interference plus Noise Radio，SINR)，进而提升***性能。5G and future communication systems introduce high-frequency frequency bands (usually considered to be above 6G), such as 28GHz, 39GHz or 60GHz frequency bands, to meet the needs of larger bandwidth and higher transmission rates. Due to the high frequency, the signal will experience severe fading during space propagation. Therefore, 5G and future communication systems use beamforming (BF) technology to obtain good directional gain to improve the directional power in the transmitting direction and improve the signal-to-interference plus Noise Radio (SINR) at the receiving end. thereby improving system performance.

波束管理的内容包括波束训练、波束测量和上报、各信号或信道波束指示等。The content of beam management includes beam training, beam measurement and reporting, and beam indication of each signal or channel.

其中，波束训练包括基站和终端两侧的收发波束扫描过程，目的是找到波束对，包括一个发波束和一个收波束。从而，使得发送波束方向和接收波束方向是对齐的，改善接收信号的增益。对于下行传输来说，波束训练过程包括P-1过程、P-2过程、P-3过程。其中，如图2所示，P-1过程是粗对齐，基站和终端通过粗波束扫描，获得一个或多个合适的波束对。P-2过程是精调基站的发波束，终端通过P-1过程获得的初始收波束训练基站的细发波束。P-3过程是精调终端的收波束，基站基于P-2获得的细发波束固定发送，训练终端的细收波束。对于上行传输来说，波束训练过程包括U-1过程、U-2过程、U-3过程。其中，如图3所示，U-1过程是粗对齐，基站和终端通过粗波束扫描，获得一个或多个合适的波束对。U-2过程是精调基站的收波束，终端通过U-1过程获得的初始发波束训练基站的细收波束。U-3过程是精调终端的发波束，基站基于U-2获得的细收波束固定发送，训练终端的细发波束。Among them, beam training includes the scanning process of transmitting and receiving beams on both sides of the base station and the terminal, and the purpose is to find beam pairs, including a transmitting beam and a receiving beam. Therefore, the direction of the transmitting beam and the direction of the receiving beam are aligned, and the gain of the received signal is improved. For downlink transmission, the beam training process includes a P-1 process, a P-2 process, and a P-3 process. Among them, as shown in Fig. 2, the P-1 process is coarse alignment, and the base station and the terminal obtain one or more suitable beam pairs through coarse beam scanning. The P-2 process is to fine-tune the transmitting beam of the base station, and the terminal uses the initial receiving beam obtained by the P-1 process to train the fine transmitting beam of the base station. The process of P-3 is to fine-tune the terminal's receiving beam, and the base station sends it fixedly based on the fine-transmission beam obtained by P-2, and trains the terminal's fine-receiving beam. For uplink transmission, the beam training process includes U-1 process, U-2 process, and U-3 process. Among them, as shown in Fig. 3, the U-1 process is coarse alignment, and the base station and the terminal obtain one or more suitable beam pairs through coarse beam scanning. The U-2 process is to fine-tune the receiving beam of the base station, and the terminal trains the fine receiving beam of the base station through the initial beam transmission obtained by the U-1 process. The U-3 process is to fine-tune the transmitting beam of the terminal, and the base station transmits it fixedly based on the fine receiving beam obtained by U-2, and trains the fine transmitting beam of the terminal.

对于上述波束训练过程，需要终端对基站配置的测量参考信号进行测量或者上报。例如，5G的Rel-15版本引入层1参考信号接收功率(layer 1 reference signal receive power，L1-RSRP)的测量来衡量波束质量。5G的Rel-16版本引入层1信号干扰噪声比(layer 1 signal interference noise ratio，L1-SINR)的测量来衡量波束质量。L1-SINR相比于L1-RSRP，可以进一步考虑干扰对波束质量的影响。For the above beam training process, the terminal needs to measure or report the measurement reference signal configured by the base station. For example, the Rel-15 version of 5G introduced the measurement of layer 1 reference signal received power (L1-RSRP) to measure beam quality. The Rel-16 version of 5G introduces the measurement of layer 1 signal interference noise ratio (L1-SINR) to measure beam quality. Compared with L1-RSRP, L1-SINR can further consider the influence of interference on beam quality.

上述波束训练过程获得的上行传输的波束对，或下行传输的波束对，可通过准共址(Quasi Co-Location，QCL)关系隐式表示。两个天线端口之间具有QCL关系，是指一个天线端口的信道大尺度参数可以通过另一个天线端口得到的信道大尺度参数推导出。或者，如果两个天线端口具有QCL关系，那么一个端口传送一个信号的信道大尺度特性可以从另一个端口传送一个信号的信道大尺度特性推断出来，也可简称为两个信号之间具有QCL关系。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。The beam pair for uplink transmission or the beam pair for downlink transmission obtained in the above beam training process may be implicitly represented by a Quasi Co-Location (QCL) relationship. There is a QCL relationship between two antenna ports, which means that the channel large-scale parameters of one antenna port can be derived from the channel large-scale parameters obtained by the other antenna port. Alternatively, if the two antenna ports have a QCL relationship, then the large-scale characteristics of the channel that transmits a signal at one port can be inferred from the large-scale characteristics of the channel that transmits a signal at the other port, also referred to simply as having a QCL relationship between the two signals . Signals corresponding to antenna ports with a QCL relationship have the same parameters, alternatively, the parameters of one antenna port can be used to determine the parameters of another antenna port with a QCL relationship to that antenna port, or both antenna ports have the same parameters , or the parameter difference between the two antenna ports is less than a certain threshold.

上述波束训练过程可将参考信号关联起来，形成TCI信息表(Contains Transmission Configuration Indicator)。当基站调度终端发送数据信息(包括：参考信号，控制信道，数据信道等)时，基站会通过下行信令将激活的TCI状态(TCI state)通知终端，从而终端能够推断出使用哪个接收波束进行接收。在整个通信过程中，如果终端移动或者波束测量事件上报，会更新相关的TCI-state信息表。The above beam training process can associate reference signals to form a TCI information table (Contains Transmission Configuration Indicator). When the base station schedules the terminal to send data information (including: reference signal, control channel, data channel, etc.), the base station will notify the terminal of the activated TCI state (TCI state) through downlink signaling, so that the terminal can infer which receiving beam to use for take over. During the whole communication process, if the terminal moves or the beam measurement event is reported, the relevant TCI-state information table will be updated.

2、波束指示信息2. Beam indication information

波束指示信息用于指示信号或信道的波束，可选的，也可通过天线面板指示信息来指示信号或信道的波束。以下实施例及相关的实施方式以波束指示信息来指示信号或信道的波束为例进行阐述。The beam indication information is used to indicate the beam of the signal or the channel. Optionally, the indication information of the antenna panel can also be used to indicate the beam of the signal or the channel. The following embodiments and related implementation manners are described by taking beam indication information to indicate a beam of a signal or a channel as an example.

上下行信号或信道可采用显式方式或隐式方式，通过QCL关系进行波束指示。显式方式是指信令为某一信道或信号配置指示使用的波束，隐式方式是通过约束或协议预定义一定的规则，规定某一信号或信道的波束。The uplink and downlink signals or channels can be indicated in an explicit manner or an implicit manner, and beam indication is performed through the QCL relationship. Explicit mode means that signaling configures a beam to be used for a certain channel or signal, and implicit mode is to predefine certain rules through constraints or protocols to specify the beam of a certain signal or channel.

2.1，显式方式指示信号或信道的波束，举例来说，如表1所示的方式。2.1. The beam of the signal or channel is indicated in an explicit manner, for example, as shown in Table 1.

High-layer RRC signaling configures a beam resource pool, activates a beam subset containing multiple beams through MAC-CE signaling, and finally triggers a beam of the beam subset through DCI to indicate the PDSCH beam. For example, the PDSCH beam is notified to the terminal through the TCI state activated in the DCI.

The upper layer RRC signaling configures a beam resource pool, and activates one of the beams through the MAC-CE signaling to indicate the PDCCH beam.

物理上行控制信道(physical uplink control channel,PUCCH)：如表1所示，采用高层RRC信令配置一个波束资源池，并通过MAC-CE信令激活其中一个波束来指示PUCCH的波束。Physical uplink control channel (PUCCH): As shown in Table 1, a high-level RRC signaling is used to configure a beam resource pool, and one of the beams is activated through MAC-CE signaling to indicate the PUCCH beam.

物理上行共享信道(physical uplink share channel,PUSCH)：如表1所示，通过与PUSCH关联的SRI指示的SRS的波束来指示该PUSCH的波束；Physical uplink shared channel (PUSCH): As shown in Table 1, the beam of the PUSCH is indicated by the beam of the SRS indicated by the SRI associated with the PUSCH;

探测参考信号(sounding reference signal，SRS)：如表1所示，对于周期SRS，通过RRC配置SRS的波束；对于半持续SRS，通过RRC配置一个波束资源池，MAC-CE指示其中一个波束作为SRS的波束；对于非周期SRS，通过RRC配置一个波束资源池，MAC-CE可以更新该波束资源池或激活其中一个波束子集，并通过DCI触发方式指示一个波束作为非周期SRS的波束。Sounding reference signal (SRS): As shown in Table 1, for periodic SRS, the beam of SRS is configured through RRC; for semi-persistent SRS, a beam resource pool is configured through RRC, and MAC-CE indicates one of the beams as SRS For aperiodic SRS, configure a beam resource pool through RRC, MAC-CE can update the beam resource pool or activate one of the beam subsets, and indicate a beam as the beam of aperiodic SRS through DCI triggering.

表1波束指示信息以显式方式确定Table 1 Beam indication information is determined in an explicit manner

2.2，隐式方式指示信号或信道的波束，举例来说：2.2, Implicitly indicating the beam of a signal or channel, for example:

PDSCH：一种情况，PDSCH与携带***信息的同步信号块(Synchronization Signal block，SSB)之间具有QCL关系。另一种情况，终端接收RRC初始配置的波束资源池，以及MAC-CE激活其中一个波束子集之前，终端假设PDSCH与初始接入使用的SSB之间具有QCL关系。其中，QCL关系的类型包括类型A(Type-A)和类型D(Type-D)。又一种情况，如果DCI中的PDSCH的TCI域未使能，则PDSCH与调度的PDCCH之间具有QCL关系，此处QCL关系的类型包括类型A(Type-A)、类型B(Type-B)、类型C(Type-C)、或类型D(Type-D)。又一种情况，如果DCI中PDSCH的TCI域未使能，当PDSCH的调度偏置小于调度门限时，PDSCH与一PDCCH具有QCL关系，该PDCCH是服务小区激活部分频带(band width part，BWP)最近的有PDCCH监控的时隙中控制资源集合标识(control resource set identity,CORESET ID)最小的PDCCH。该QCL关系的类型为Type-A、Type-B、Type-C、或Type-D；如果是多站点场景，则所关联的CORESET需要限制在同一站点内。又一种情况，多站点场景，如果PDSCH的RRC配置包括至少一个具有两个TCI指示的配置，则当前PDSCH的调度偏置小于调度门限时，则PDSCH使用最小ID的具有两个TCI指示的配置。又一种情况，跨载波调度场景，当DCI中的PDSCH的TCI域使能，且PDSCH的调度偏置小于调度门限时，PDSCH的QCL假设参考调度后的载波上，PDSCH激活的TCI的ID最小的TCI state。PDSCH: In a case, there is a QCL relationship between PDSCH and a synchronization signal block (Synchronization Signal block, SSB) that carries system information. In another case, before the terminal receives the beam resource pool initially configured by RRC, and before the MAC-CE activates one of the beam subsets, the terminal assumes that there is a QCL relationship between the PDSCH and the SSB used for initial access. The types of the QCL relationship include Type A (Type-A) and Type D (Type-D). In another case, if the TCI field of the PDSCH in the DCI is not enabled, there is a QCL relationship between the PDSCH and the scheduled PDCCH, where the types of the QCL relationship include Type A (Type-A) and Type B (Type-B). ), Type C (Type-C), or Type D (Type-D). In another case, if the TCI field of the PDSCH in the DCI is not enabled, when the scheduling offset of the PDSCH is less than the scheduling threshold, the PDSCH has a QCL relationship with a PDCCH, and the PDCCH is the active part of the frequency band (band width part, BWP) of the serving cell. The PDCCH with the smallest control resource set identity (CORESET ID) in the nearest time slot monitored by the PDCCH. The type of the QCL relationship is Type-A, Type-B, Type-C, or Type-D; if it is a multi-site scenario, the associated CORESET needs to be restricted to the same site. In another case, in a multi-site scenario, if the RRC configuration of the PDSCH includes at least one configuration with two TCI indications, when the scheduling offset of the current PDSCH is less than the scheduling threshold, the PDSCH uses the configuration with the smallest ID and two TCI indications. . In another case, in the cross-carrier scheduling scenario, when the TCI field of the PDSCH in the DCI is enabled and the scheduling offset of the PDSCH is less than the scheduling threshold, the QCL of the PDSCH is assumed to refer to the scheduled carrier, and the ID of the TCI activated by the PDSCH is the smallest. the TCI state.

其中，调度门限是指一个调度时长，该调度时长包括DCI译码解析时长和波束查找、准备、切换等处理时长。The scheduling threshold refers to a scheduling duration, and the scheduling duration includes the DCI decoding and parsing duration and processing durations such as beam search, preparation, and handover.

PDCCH：一种情况，对于通常的PDCCH，与携带***信息的SSB具有QCL关系。另一种情况，对于非ID#0的CORESET，如果没有配置TCI-state，或者初始RRC配置了多个TCI-state，且MAC-CE没有激活，则与初始接入的SSB具有QCL关系。又一种情况，对于非ID#0的CORESET，如果(在小区切换(handover,HO)或者辅小区(Scell)添加过程中)RRC配置了多个TCI-state，且MAC-CE没有激活，则与该过程发起的随机接入的SSB具有QCL关系。又一种情况，对于ID#0的CORESET，如果没有配置TCI-state，或者初始RRC配置了多个TCI-state，且MAC-CE没有激活，则与初始接入的SSB具有QCL关系。PDCCH: A case, for a normal PDCCH, there is a QCL relationship with the SSB that carries system information. In another case, for a CORESET other than ID#0, if no TCI-state is configured, or multiple TCI-states are configured in the initial RRC, and the MAC-CE is not activated, it has a QCL relationship with the initially accessed SSB. In another case, for a CORESET other than ID#0, if (during cell handover (HO) or secondary cell (Scell) addition) multiple TCI-states are configured in RRC and MAC-CE is not activated, then Has a QCL relationship with the SSB for random access initiated by this procedure. In another case, for the CORESET of ID #0, if no TCI-state is configured, or multiple TCI-states are configured in the initial RRC, and the MAC-CE is not activated, it has a QCL relationship with the initially accessed SSB.

CSI-RS：对于周期、半持续CSI-RS未定义默认波束。对于非周期CSI-RS波束，如果调度偏置小于调度门限时，如果同一符号上有其它指示了波束的信道或信号时，则使用其它的信道或信号的波束，如果没有则与一PDCCH具有QCL关系，该PDCCH是服务小区激活BWP最近的有PDCCH监控的slot上CORESET ID最小的PDCCH。CSI-RS: No default beam is defined for periodic, semi-persistent CSI-RS. For aperiodic CSI-RS beams, if the scheduling offset is less than the scheduling threshold, if there are other channels or signals indicating the beam on the same symbol, the beams of other channels or signals are used, and if not, it has a QCL with a PDCCH relationship, the PDCCH is the PDCCH with the smallest CORESET ID on the slot with the nearest PDCCH monitoring where the serving cell activates the BWP.

其中，未定义默认波束是指若波束没有通过显式指示，且协议未规定终端的波束接收行为，则终端可自己实现确定波束。The undefined default beam means that if the beam does not pass the explicit indication and the protocol does not specify the beam receiving behavior of the terminal, the terminal can determine the beam by itself.

PUCCH：一种情况，如果没有配置主小区(pathloss reference signal,PL-RS)，没有配置上行波束，且配置了默认波束，则参考主小区(primary cell,PCell)激活BWP且ID最小的 CORESET的波束。PUCCH: In one case, if the primary cell (pathloss reference signal, PL-RS) is not configured, the uplink beam is not configured, and the default beam is configured, the reference primary cell (PCell) activates BWP and the CORESET with the smallest ID beam.

PUSCH：一种情况，当PUSCH由DCI 0_0调度时，波束参考该载波(carrier component,CC)激活BWP专用的CORESET ID最小的PUCCH的波束。另一种情况，当PUSCH由DCI0_0调度时，且默认波束功能使能时，如果在连接态激活上行BWP内没有配置PUCCH，则波束参考该CC激活BWP内ID最小的CORESET的波束。又一种情况，当PUSCH由DCI 0_0调度时，且默认波束功能使能时，如果在连接态激活上行BWP内没有配置PUCCH或者配置的PUCCH没有波束参考，则波束参考该CC激活BWP内ID最小的CORESET的波束。PUSCH: In a case, when the PUSCH is scheduled by DCI 0_0, the beam refers to the carrier component (CC) to activate the beam of the PUCCH with the smallest CORESET ID dedicated to the BWP. In another case, when the PUSCH is scheduled by DCI0_0 and the default beam function is enabled, if the PUCCH is not configured in the activated uplink BWP in the connected state, the beam refers to the CORESET beam with the smallest ID in the CC activated BWP.

Alternatively, the determination time of the beam indication information is the reception time of the signal or channel having the above-mentioned QCL relationship with the PDCCH.

请参阅图5，图5是目前的一种波束查找方法的示意图。如图5所示，以终端接收PDSCH为例，终端接收DCI，该DCI用于调度终端在传输时刻N接收PDSCH，并且其中的波束指示信息指示终端采用波束#2接收PDSCH，该PDSCH占用7个符号，协议或标准规定波束查找的起始时刻为该传输时刻N。因此，终端在传输时刻N为起始查找波束、准备波束以及切换波束，如图5所示，波束处理时长为3个符号，从而导致该三个符号上的数据无法接收，进而导致PDSCH接收不完整；另外，若PDSCH中的解调参考信号在该三个符号中，则可能导致无法进行信道估计，进而无法收到该PDSCH。Please refer to FIG. 5 , which is a schematic diagram of a current beam search method. As shown in FIG. 5 , taking the terminal receiving PDSCH as an example, the terminal receives DCI, which is used to schedule the terminal to receive the PDSCH at the transmission time N, and the beam indication information in it indicates that the terminal uses beam #2 to receive the PDSCH, and the PDSCH occupies 7 The symbol, protocol or standard stipulates that the start time of beam search is the transmission time N. Therefore, the terminal starts searching for the beam, preparing the beam and switching the beam at the transmission time N. As shown in Figure 5, the beam processing time is 3 symbols, so that the data on the three symbols cannot be received, which in turn leads to the failure of PDSCH reception. In addition, if the demodulation reference signal in the PDSCH is in the three symbols, it may cause that channel estimation cannot be performed, and thus the PDSCH cannot be received.

请参阅图6，图6是本申请实施例提供的一种波束查找方法的示意图。如图6所示，以终端接收PDSCH为例，终端接收DCI，该DCI用于调度终端在传输时刻N接收PDSCH，并且其中的波束指示信息指示终端采用波束#2接收PDSCH，该PDSCH占用7个符号，波束查找的起始时刻M可为该DCI的接收时刻与传输时刻N之间的某个时刻，假设波束查找的起始时刻M如图6所示，是传输时刻N提前时长K的时刻。可见，终端可在时刻M即可提前查找波束，有利于在传输时刻N准备好PDSCH的接收波束，从而避免PDSCH接收不完整或无法接收的问题。Please refer to FIG. 6. FIG. 6 is a schematic diagram of a beam search method provided by an embodiment of the present application. As shown in FIG. 6 , taking the terminal receiving PDSCH as an example, the terminal receives DCI, which is used to schedule the terminal to receive the PDSCH at the transmission time N, and the beam indication information in it indicates that the terminal uses beam #2 to receive the PDSCH, and the PDSCH occupies 7 symbol, the starting time M of the beam search can be a certain time between the receiving time of the DCI and the transmission time N, assuming that the starting time M of the beam search is shown in Figure 6, which is the time when the transmission time N is advanced by the length K . It can be seen that the terminal can search for the beam in advance at the time M, which is beneficial to prepare the receiving beam of the PDSCH at the transmission time N, thereby avoiding the problem that the PDSCH reception is incomplete or cannot be received.

另外，该时刻M是波束指示信息的确定时刻之后以及传输时刻N之前的时刻，还可以表述为：时刻M是传输时刻N提前时长K对应的时刻。该时长K大于零且不大于波束指示信息的确定时刻与传输时刻N之间的时间间隔。本文所述的时刻、时间间隔、时长的单位为时间单元、秒、或微秒等。例如，时刻M或传输时刻N可对应帧n中的时隙0中的符号0的起始时刻；时长K可对应1个或多个符号、时隙、或微时隙等。In addition, the time M is the time after the determination time of the beam indication information and before the transmission time N, and it can also be expressed as: the time M is the time corresponding to the advance time K of the transmission time N. The duration K is greater than zero and not greater than the time interval between the determination moment of the beam indication information and the transmission moment N. The units of time, time interval, and duration described herein are time units, seconds, or microseconds, and the like. For example, time M or transmission time N may correspond to the start time of symbol 0 in time slot 0 in frame n; duration K may correspond to one or more symbols, time slots, or mini-slots.

另一种实施方式中，时刻M是是波束池更新时刻之后以及时刻N之前的时刻。其中，波束指示信息所指示的波束包括于波束池更新时刻之后激活(或生效或更新)的波束池中。其中，该波束池可以是RRC配置的波束资源池，也可以是MAC-CE激活的波束子集。具体的，与传输时刻N传输的信号或信道有关。In another embodiment, time M is the time after the beam pool update time and before time N. The beam indicated by the beam indication information is included in the beam pool activated (or valid or updated) after the beam pool update time. The beam pool may be a beam resource pool configured by RRC, or may be a subset of beams activated by MAC-CE. Specifically, it is related to the signal or channel transmitted at the transmission time N.

例如，对于PDSCH来说，波束池更新时刻为终端接收到MAC-CE的时刻或之后间隔时长L的时刻，L大于零且小于该MAC-CE的接收时刻与传输时刻N之间的时间间隔，该MAC-CE用于激活RRC配置的波束资源池中的一个波束子集。For example, for PDSCH, the beam pool update time is the time when the terminal receives the MAC-CE or the time interval L after that, where L is greater than zero and less than the time interval between the reception time of the MAC-CE and the transmission time N, The MAC-CE is used to activate a beam subset in the beam resource pool configured by the RRC.

对于PDCCH来说，波束池更新时刻为终端接收到RRC信令的时刻或之后间隔时长L的时刻，L大于零且小于该RRC的接收时刻与传输时刻N之间的时间间隔，该RRC信令用于激活配置的波束资源池。For PDCCH, the beam pool update time is the time when the terminal receives the RRC signaling or the time interval L after that. L is greater than zero and less than the time interval between the reception time of the RRC and the transmission time N. The RRC signaling The beam resource pool used to activate the configuration.

对于非周期CSI-RS来说，波束池更新时刻为终端接收到MAC-CE信令的时刻或之后间隔时长L的时刻，L大于零且小于该MAC-CE的接收时刻与传输时刻N之间的时间间隔，该MAC-CE信令用于激活RRC配置的波束资源池中的一个波束子集。For aperiodic CSI-RS, the beam pool update time is the time when the terminal receives the MAC-CE signaling or the time interval L after that, where L is greater than zero and less than the time between the reception time of the MAC-CE and the transmission time N The MAC-CE signaling is used to activate a beam subset in the beam resource pool configured by the RRC.

对于PUCCH来说，波束池更新时刻为终端接收到RRC信令的时刻或之后间隔时长L的时刻，L大于零且小于该RRC的接收时刻与传输时刻N之间的时间间隔，该RRC信令用于激活配置的波束资源池。For PUCCH, the beam pool update time is the time when the terminal receives the RRC signaling or the time interval L after that. L is greater than zero and less than the time interval between the reception time of the RRC and the transmission time N. The RRC signaling The beam resource pool used to activate the configuration.

对于PUSCH来说，PUSCH的波束指示信息是基于与PUSCH关联的SRI指示的SRS的波束获得的，故PUSCH的波束池更新时刻为SRS对应的RRC信令的接收时刻或之后间隔时长L的时刻，L大于零且小于该RRC的接收时刻与传输时刻N之间的时间间隔。该RRC信令用于配置一个波束资源池。For PUSCH, the beam indication information of PUSCH is obtained based on the beam of the SRS indicated by the SRI associated with the PUSCH, so the update time of the beam pool of the PUSCH is the reception time of the RRC signaling corresponding to the SRS or the time interval L after that, L is greater than zero and less than the time interval between the reception moment of the RRC and the transmission moment N. The RRC signaling is used to configure a beam resource pool.

对于非周期SRS来说，波束池更新时刻为终端接收到MAC-CE信令的时刻或之后间隔时长L的时刻，L大于零且小于该MAC-CE的接收时刻与传输时刻N之间的时间间隔，该MAC-CE信令用于激活RRC配置的波束资源池中的一个波束子集。For aperiodic SRS, the beam pool update time is the time when the terminal receives the MAC-CE signaling or the time interval L after that, where L is greater than zero and less than the time between the reception time of the MAC-CE and the transmission time N interval, the MAC-CE signaling is used to activate a beam subset in the beam resource pool configured by the RRC.

另外，对于隐式方式指示上述信号或信道的波束的情况，可根据与这些信号或信道具有QCL关系的其他信号或信道的波束池更新时刻，确定这些信号或信道的波束池更新时刻。例如，采用隐式方式指示PDSCH的波束时，PDSCH的波束池更新时刻为与PDSCH具有QCL关系的PDCCH的波束池更新时刻。其中，PDCCH的波束池更新时刻，为配置波束资源池的RRC信令的接收时刻或之后间隔时长L的时刻，L大于零且小于该RRC的接收时刻与传输时刻N之间的时间间隔。In addition, for the case of implicitly indicating the beams of the above-mentioned signals or channels, the beam pool update time of these signals or channels can be determined according to the beam pool update time of other signals or channels having a QCL relationship with these signals or channels. For example, when the PDSCH beam is indicated in an implicit manner, the update time of the beam pool of PDSCH is the update time of the beam pool of PDCCH having a QCL relationship with PDSCH. The beam pool update time of the PDCCH is the reception time of the RRC signaling configuring the beam resource pool or the time interval L after that, where L is greater than zero and less than the time interval between the reception time of the RRC and the transmission time N.

可以理解，上述提及的波束子集可以包括一个或多个波束。It can be understood that the beam subset mentioned above may include one or more beams.

请参阅图7，图7是本申请实施例提供的一种波束查找方法的示意图，如图7所示，在波束池更新时刻之前所激活的波束子集{波束#0、波束#1、波束#2}的波束方向与波束池更新时刻之后所激活的波束子集{波束#0、波束#1、波束#2}的波束方向并不相同，也就是波束池更新时刻前后激活的波束并不相同，这里的不同包括部分不同或全部不同，因此，查找波束的起始时刻M在波束池更新时刻之后以及传输时刻N之前，有利于保证在传输时刻N波束准备完毕，还避免波束查找过早，比如在波束池更新时刻之前查找的波束#2与波束池更新时刻之后查找的波束#2并不相同，所导致的波束不对齐的问题。Please refer to FIG. 7. FIG. 7 is a schematic diagram of a beam search method provided by an embodiment of the present application. As shown in FIG. 7, a subset of beams {beam #0, beam #1, beam The beam direction of #2} is not the same as the beam direction of the activated beam subset {beam #0, beam #1, beam #2} after the update time of the beam pool, that is, the beams activated before and after the update time of the beam pool are not the same. The same, the difference here includes some or all differences. Therefore, the starting time M of the search beam is after the beam pool update time and before the transmission time N, which is beneficial to ensure that the beam is ready at the transmission time N, and also avoid beam search too early. For example, the beam #2 searched before the update time of the beam pool is different from the beam #2 searched after the update time of the beam pool, resulting in the problem of beam misalignment.

另外，本文所述的时刻M或时长K可以是预定义的，或是基于预定规则推导获得的。In addition, the time M or the duration K described herein may be predefined, or derived based on a predetermined rule.
