本公开实施例涉及的执行主体包括但不限于:支持蜂窝移动通信的手机终端等UE,以及基站等。The execution bodies involved in the embodiments of the present disclosure include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication, and base stations.
本公开实施例的一个应用场景为,空闲态UE和非激活态UE可以共享连接态UE使用跟踪参考信号(TRS,Tracking Reference Signal)/信道状态指示参考信号(CSI-RS,Channel State Information-Reference Signal)配置,即空闲态UE和非激活态UE可以使用共享TRS/CSI-RS。An application scenario of the embodiment of the present disclosure is that the UE in the idle state and the UE in the inactive state can share the tracking reference signal (TRS, Tracking Reference Signal)/Channel State Indication Reference Signal (CSI-RS, Channel State Information-Reference used by the UE in the connected state) Signal) configuration, that is, idle UEs and inactive UEs can use shared TRS/CSI-RS.
连接态UE使用TRS/CSI-RS实际面向小区或者一组UE,因此TRS/CSI-RS配置不会考虑和PO之间的关系。Connected UEs use TRS/CSI-RS to actually face a cell or a group of UEs, so the TRS/CSI-RS configuration does not consider the relationship with PO.
相关技术中,UE在非小区中心时或一些场景时,可以通过接收3个周期的SSB来进行精同步;这样导致同步效率比较低。本公开实施例中,为了提高同步效率,提出了一种信息传输方法,期望能给UE配置的TRS/CSI-RS,以通过更少的SSB(例如那么可以通过一个周期的SSB)来同步。即,空闲态UE和非激活态UE可以使用共享TRS/CSI-RS辅助进行同步。In the related art, when the UE is not in the center of the cell or in some scenarios, the UE can perform fine synchronization by receiving SSBs for 3 periods; this results in a relatively low synchronization efficiency. In the embodiment of the present disclosure, in order to improve the synchronization efficiency, an information transmission method is proposed, and it is expected that the TRS/CSI-RS configured for the UE can be synchronized through fewer SSBs (for example, a period of SSBs can be used). That is, idle state UEs and inactive state UEs can use shared TRS/CSI-RS assistance for synchronization.
如图2所示,本示例性实施例提供一种信息传输方法,信息传输方法可以应用于蜂窝移动通信系统的基站中,包括:As shown in FIG. 2, this exemplary embodiment provides an information transmission method, which can be applied to a base station of a cellular mobile communication system, including:
步骤201:发送共享跟踪参考信号TRS/信道状态信息参考信号CSI-RS的信号配置信息,其中,所述信号配置信息,至少包括:所述共享TRS/CSI-RS所关联的波束的波束信息其中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE针对与所述共享TRS/CSI-RS关联的波束进行相应操作。Step 201: Send the signal configuration information of the shared tracking reference signal TRS/channel state information reference signal CSI-RS, wherein the signal configuration information includes at least: beam information of the beam associated with the shared TRS/CSI-RS wherein , the shared TRS/CSI-RS is at least used for the idle state UE and/or the inactive state UE to perform corresponding operations on the beam associated with the shared TRS/CSI-RS.
在一些实施例中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE进行同步。In some embodiments, the shared TRS/CSI-RS is at least used for synchronization of idle UEs and/or inactive UEs.
这里,UE可以是采用蜂窝移动通信技术进行无线通信的手机终端等。基站可以是在蜂窝移动通信系统中,向UE提供接入网接口的通信设备。Here, the UE may be a mobile phone terminal or the like that uses a cellular mobile communication technology to perform wireless communication. The base station may be a communication device that provides an access network interface to a UE in a cellular mobile communication system.
在无线信号的测量中,UE可以针对基站发送的TRS/CSI-RS进行测量。In the measurement of wireless signals, the UE may measure the TRS/CSI-RS sent by the base station.
CSI-RS可以用于供UE获取以下的至少一个参数:信道的状态、波束管理、移动性管理、速率匹配等。The CSI-RS can be used for the UE to obtain at least one of the following parameters: channel status, beam management, mobility management, rate matching, and the like.
基站和UE物理晶振的频率是会有小小的偏差的,不可能做到完全一致,这使得UE接收到的射频载波信号会有相位上的偏差;在接收子载波的解调符号星座图上,表现为相位上的旋转,即接收的调制符号偏离了一定的相位角度,这是由于频偏在时间上的积累造成的。这个时候,需要跟踪参考信号(tracking reference signal,TRS)来追踪其它数据信号的旋转相位。 TRS是一种多周期的CSI-RS,确切的说是一个4-1端口,3个CSI-RS密度,位于连续两个时隙的NZP-CSI-RS,在一个时隙内时间上两个TRS最小间隔是4个OFDM符号,频域上间隔4个子载波。可以根据TRS来估算频率和时间上的误差。接收数据补偿这些误差,即可旋回原始发送的调制坐标位置。The frequency of the physical crystal oscillator of the base station and the UE will have a small deviation, and it is impossible to be completely consistent, which will cause the radio frequency carrier signal received by the UE to have a phase deviation; on the demodulation symbol constellation diagram of the received subcarrier , which manifests as a rotation in phase, that is, the received modulation symbol deviates from a certain phase angle, which is caused by the accumulation of frequency offset in time. At this time, a tracking reference signal (TRS) is required to track the rotational phase of other data signals. TRS is a multi-period CSI-RS, to be precise, a 4-1 port, 3 CSI-RS density, NZP-CSI-RS located in two consecutive time slots, two time in one time slot The minimum interval of TRS is 4 OFDM symbols, and the interval is 4 subcarriers in the frequency domain. Errors in frequency and time can be estimated from TRS. The received data compensates for these errors, and the original transmitted modulation coordinates can be rotated back.
这里,共享的TRS/CSI-RS可以是供空闲态UE和/或非激活态UE使用,且与连接态UE共享的TRS/CSI-RS。空闲态UE和/或非激活态UE,可以与连接态UE在共享的TRS/CSI-RS时机对TRS/CSI-RS进行监听。Here, the shared TRS/CSI-RS may be the TRS/CSI-RS used by idle UEs and/or inactive UEs and shared with connected UEs. The idle state UE and/or the inactive state UE may monitor the TRS/CSI-RS at the shared TRS/CSI-RS timing with the connected state UE.
波束是一种通信资源,可以是宽波束,也可以是窄波束,还可以是其他类型波束。波束可以通过波束成形技术形成的具有特定指向的波束。这里,波束成形技术可以包括但不限于数值波束成形技术、模拟波束成形技术或混合数字模拟波束成形技术等。A beam is a communication resource, which can be a wide beam, a narrow beam, or other types of beams. The beam can be formed by beamforming technology with a specific direction of the beam. Here, the beamforming technology may include, but is not limited to, a numerical beamforming technology, an analog beamforming technology, a hybrid digital-analog beamforming technology, and the like.

In one embodiment, the signal configuration information includes at least: beam information of two or more beams associated with the shared TRS/CSI-RS; wherein each of the shared TRS/CSI-RS is associated with The beam information of the beams is not exactly the same or not at all.
在一些实施例中,所述信号配置信息中可以包括一个或多个共享TRS/CSI-RS。在一些实施例中,一个TRS/CSI-RS可以关联于一个或多个波束。在一些实施例中,不同的共享TRS/CSI-RS可以关联于不同的波束。基站可以通过不同的波束发送不同的共享TRS/CSI-RS。波束信息可以用于指示波束。波束信息可以是唯一指示波束的信息。例如,波束信息可以用于指示波束的标识等。In some embodiments, the signal configuration information may include one or more shared TRS/CSI-RS. In some embodiments, one TRS/CSI-RS may be associated with one or more beams. In some embodiments, different shared TRS/CSI-RS may be associated with different beams. The base station can transmit different shared TRS/CSI-RS through different beams. Beam information can be used to indicate beams. The beam information may be the information that uniquely indicates the beam. For example, the beam information may be used to indicate the identity of the beam, and the like.
在一些实施例中,UE可以基于波束信息确定与共享TRS/CSI-RS关联的波束。例如,UE可以基于波束信息确定用于接收所述共享TRS/CSI-RS 的波束,从而接收共享TRS/CSI-RS。In some embodiments, the UE may determine the beam associated with the shared TRS/CSI-RS based on the beam information. For example, the UE may determine a beam for receiving the shared TRS/CSI-RS based on the beam information, thereby receiving the shared TRS/CSI-RS.
如此,通过在共享TRS/CSI-RS的测量指示信息中携带的波束信息,可以显性的指示共享TRS/CSI-RS所关联的波束。UE可以基于波束信息准确地确定共享TRS/CSI-RS所关联的波束。In this way, the beam associated with the shared TRS/CSI-RS can be explicitly indicated by the beam information carried in the measurement indication information of the shared TRS/CSI-RS. The UE can accurately determine the beam associated with the shared TRS/CSI-RS based on the beam information.
在一个实施例中,所述波束信息,包括以下至少之一:In one embodiment, the beam information includes at least one of the following:
指示SSB的索引Index的指示信息;Indication information indicating the index Index of the SSB;
指示所述Index的QCL参数的指示信息。Indication information indicating the QCL parameter of the Index.
SSB index可以用于唯一标识波束。The SSB index can be used to uniquely identify the beam.
准共站址(QCL)可以指示出波束信息参考信号身份标识(ID),还可以指示波束对应的天线端口、天线面板、发送接收点、物理小区的身份标识(ID)中的至少一种。这样,使得波束的指示更加准确。The Quasi Co-Location (QCL) can indicate the beam information reference signal identity (ID), and can also indicate at least one of the antenna port, antenna panel, transmitting and receiving point, and physical cell identity (ID) corresponding to the beam. In this way, the indication of the beam is made more accurate.
UE可以基于波束信息确定共享TRS/CSI-RS关联的波束。如此,UE可以准确地确定共享TRS/CSI-RS关联的波束。The UE may determine the beams sharing the TRS/CSI-RS association based on the beam information. In this way, the UE can accurately determine the beams that share the TRS/CSI-RS association.
在一个实施例中,所述方法还包括:In one embodiment, the method further includes:
UE基于所述信号配置信息,根据当前波束的波束信息,确定所述当前波束关联的所述共享TRS/CSI-RS。The UE determines the shared TRS/CSI-RS associated with the current beam according to the beam information of the current beam based on the signal configuration information.
在一个实施例中,UE可以基于信号配置信息确定不同所述TRS/CSI-RS与不同波束的波束信息的对应关系。In one embodiment, the UE may determine the correspondence between different TRS/CSI-RS and beam information of different beams based on the signal configuration information.
UE根据当前波束的波束信息,确定当前波束所关联的共享TRS/CSI-RS。The UE determines the shared TRS/CSI-RS associated with the current beam according to the beam information of the current beam.
示例性的,UE根据当前波束的波束信息的SSB的索引和/或QCL参数,从信号配置信息中,确定出SSB的索引和/或QCL参数对应的共享TRS/CSI-RS。Exemplarily, the UE determines the shared TRS/CSI-RS corresponding to the SSB index and/or the QCL parameter from the signal configuration information according to the SSB index and/or the QCL parameter of the beam information of the current beam.
如此,UE基于波束信息与共享TRS/CSI-RS的对应关系,确定当前波束对应的共享TRS/CSI-RS,提高确定当前波束对应的共享TRS/CSI-RS的 准确性。In this way, the UE determines the shared TRS/CSI-RS corresponding to the current beam based on the correspondence between the beam information and the shared TRS/CSI-RS, and improves the accuracy of determining the shared TRS/CSI-RS corresponding to the current beam.
在一个实施例中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE针对与所述共享TRS/CSI-RS关联的波束的同步。In one embodiment, the shared TRS/CSI-RS is used at least for synchronization of idle UEs and/or inactive UEs for beams associated with the shared TRS/CSI-RS.
在一个实施例中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE针对与所述共享TRS/CSI-RS关联的波束的无线信号测量。In one embodiment, the shared TRS/CSI-RS is at least used for wireless signal measurements by idle UEs and/or inactive UEs for beams associated with the shared TRS/CSI-RS.
UE确定当前波束关联的共享TRS/CSI-RS后,响应于UE检测到当前波束关联的共享TRS/CSI-RS,UE可以采用共享TRS/CSI-RS进行同步或无线信号测。After the UE determines the shared TRS/CSI-RS associated with the current beam, in response to the UE detecting the shared TRS/CSI-RS associated with the current beam, the UE may use the shared TRS/CSI-RS for synchronization or radio signal measurement.
这里,无线信号测量可以是RRM测量。Here, the wireless signal measurement may be an RRM measurement.
响应于UE确定当前波束具有关联的共享TRS/CSI-RS,UE可以不再使用SSB进行同步或无线信号测量。由于相关技术中,UE需要采用3个SSB周期进行同步;而本公开实施例的技术方案采用共享TRS/CSI-RS进行同步,只需要一个SSB周期。因此,采用共享TRS/CSI-RS同步可以减少UE唤醒时间,降低UE的功耗。In response to the UE determining that the current beam has an associated shared TRS/CSI-RS, the UE may no longer use the SSB for synchronization or radio signal measurements. Because in the related art, the UE needs to use 3 SSB cycles for synchronization; while the technical solutions of the embodiments of the present disclosure use shared TRS/CSI-RS for synchronization, and only one SSB cycle is required. Therefore, the use of shared TRS/CSI-RS synchronization can reduce the wake-up time of the UE and reduce the power consumption of the UE.
响应于UE确定当前波束具有关联的共享TRS/CSI-RS,UE也可以使用SSB进行同步或无线信号测量。The UE may also use the SSB for synchronization or radio signal measurements in response to the UE determining that the current beam has an associated shared TRS/CSI-RS.

在一个实施例中,所述方法还包括:发送生效指示,用于指示所述波束信息是否生效。In one embodiment, the method further includes: sending a valid indication, which is used to indicate whether the beam information is valid.
在本公开实施例中,该生效指示可以承载在任何恰当的信令中,本公 开实施例并不对此作出限定。例如,该生效指示可以承载在信号配置信息中。In the embodiment of the present disclosure, the validation indication may be carried in any appropriate signaling, which is not limited in the embodiment of the present disclosure. For example, the validation indication may be carried in the signal configuration information.
生效指示可以指示信号配置信息所配置的共享TRS和/或CSI-RS关联的波束的波束信息是否生效。如果生效,UE可以基于信号配置信息确定不同共享TRS和/或CSI-RS关联的波束的波束信息;否则,UE不再基于信号配置信息确定不同共享TRS和/或CSI-RS关联的波束的波束信息。The validation indication may indicate whether the beam information of the beam associated with the shared TRS and/or CSI-RS configured by the signal configuration information is valid.

如图3所示,本示例性实施例提供一种信息传输方法,信息传输方法可以应用于蜂窝移动通信系统的空闲态用户设备UE和/或非激活态UE中,包括:As shown in FIG. 3 , this exemplary embodiment provides an information transmission method, and the information transmission method can be applied to an idle state user equipment UE and/or an inactive state UE of a cellular mobile communication system, including:
步骤301:接收共享跟踪参考信号TRS/信道状态信息参考信号CSI-RS的信号配置信息,其中,所述信号配置信息,至少包括:所述共享TRS/CSI-RS所关联的波束的波束信息,其中,所述共享TRS/CSI-RS至少用于供所述空闲态UE和/或所述非激活态UE针对与所述共享TRS/CSI-RS关联的波束进 行相应操作。Step 301: Receive signal configuration information of a shared tracking reference signal TRS/channel state information reference signal CSI-RS, where the signal configuration information at least includes: beam information of a beam associated with the shared TRS/CSI-RS, Wherein, the shared TRS/CSI-RS is at least used for the idle state UE and/or the inactive state UE to perform corresponding operations on the beam associated with the shared TRS/CSI-RS.
这里,UE可以是采用蜂窝移动通信技术进行无线通信的手机终端等。基站可以是在蜂窝移动通信系统中,向UE提供接入网接口的通信设备。Here, the UE may be a mobile phone terminal or the like that uses a cellular mobile communication technology to perform wireless communication. The base station may be a communication device that provides an access network interface to a UE in a cellular mobile communication system.
在一些实施例中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE进行同步。In some embodiments, the shared TRS/CSI-RS is at least used for synchronization of idle UEs and/or inactive UEs.
在无线信号的测量中,UE可以针对基站发送的TRS/CSI-RS进行测量。In the measurement of wireless signals, the UE may measure the TRS/CSI-RS sent by the base station.

.
基站和UE物理晶振的频率是会有小小的偏差的,不可能做到完全一致,这使得UE接收到的射频载波信号会有相位上的偏差,在接收子载波的解调符号星座图上,表现为相位上的旋转,即接收的调制符号偏离了一定的相位角度,这是由于频偏在时间上的积累造成的。这个时候,需要跟踪参考信号(tracking reference signal,TRS)来追踪其它数据信号的旋转相位。TRS是一种多周期的CSI-RS,确切的说是一个4-1端口,3个CSI-RS密度,位于连续两个时隙的NZP-CSI-RS,在一个时隙内时间上两个TRS最小间隔是4个OFDM符号,频域上间隔4个子载波。可以根据TRS来估算频率和时间上的误差。接收数据补偿这些误差,即可旋回原始发送的调制坐标位置。The frequency of the physical crystal oscillator of the base station and the UE will have a small deviation, and it is impossible to be completely consistent, which will cause the RF carrier signal received by the UE to have a phase deviation. , which manifests as a rotation in phase, that is, the received modulation symbol deviates from a certain phase angle, which is caused by the accumulation of frequency offset in time. At this time, a tracking reference signal (TRS) is required to track the rotational phase of other data signals. TRS is a multi-period CSI-RS, to be precise, a 4-1 port, 3 CSI-RS density, NZP-CSI-RS located in two consecutive time slots, two time in one time slot The minimum interval of TRS is 4 OFDM symbols, and the interval is 4 subcarriers in the frequency domain. Errors in frequency and time can be estimated from TRS. The received data compensates for these errors, and the original transmitted modulation coordinates can be rotated back.
这里,共享的TRS/CSI-RS可以是供空闲态UE和/或非激活态UE使用,且与连接态UE共享的TRS/CSI-RS。空闲态UE和/或非激活态UE,可以与连接态UE在共享的TRS/CSI-RS时机对TRS/CSI-RS进行监听。Here, the shared TRS/CSI-RS may be the TRS/CSI-RS used by idle UEs and/or inactive UEs and shared with connected UEs. The idle state UE and/or the inactive state UE may monitor the TRS/CSI-RS at the shared TRS/CSI-RS timing with the connected state UE.

In some embodiments, one TRS/CSI-RS may be associated with one or more beams. In some embodiments, different shared TRS/CSI-RS may be associated with different beams. The base station can transmit different shared TRS/CSI-RS through different beams. Beam information can be used to indicate beams. The beam information may be the information that uniquely indicates the beam. For example, the beam information may be used to indicate the identity of the beam, and the like.
在一些实施例中,UE可以基于波束信息确定与共享TRS/CSI-RS关联的波束。例如,UE可以基于波束信息确定用于接收所述共享TRS/CSI-RS的波束,从而接收共享TRS/CSI-RS。In some embodiments, the UE may determine the beam associated with the shared TRS/CSI-RS based on the beam information. For example, the UE may determine a beam for receiving the shared TRS/CSI-RS based on the beam information, thereby receiving the shared TRS/CSI-RS.
如此,通过在共享TRS/CSI-RS的测量指示信息中携带波束信息,可以显性的指示共享TRS/CSI-RS所关联的波束。UE可以基于波束信息准确地确定共享TRS/CSI-RS所关联的波束。In this way, by carrying beam information in the measurement indication information of the shared TRS/CSI-RS, the beam associated with the shared TRS/CSI-RS can be explicitly indicated. The UE can accurately determine the beam associated with the shared TRS/CSI-RS based on the beam information.
在一个实施例中,所述波束信息,包括以下至少之一:In one embodiment, the beam information includes at least one of the following:

准共站址(QCL)可以指示出波束信息参考信号身份标识(ID),还可以指示波束对应的天线端口、天线面板、发送接收点、物理小区的身份标识(ID)中的至少一种。这样,使得波束的指示更加准确。The Quasi-Co-Location (QCL) can indicate the beam information reference signal identity (ID), and can also indicate at least one of the antenna port, antenna panel, transmitting and receiving point, and physical cell identity (ID) corresponding to the beam. In this way, the indication of the beam is made more accurate.
UE可以基于波束信息确定共享TRS/CSI-RS关联的波束。The UE may determine the beams sharing the TRS/CSI-RS association based on the beam information.
如此,UE可以准确地确定共享TRS/CSI-RS关联的波束。In this way, the UE can accurately determine the beams that share the TRS/CSI-RS association.
在一个实施例中,所述方法还包括:In one embodiment, the method further includes:
基于所述信号配置信息,根据当前波束的波束信息,确定所述当前波束关联的所述共享TRS/CSI-RS。Based on the signal configuration information, and according to beam information of the current beam, the shared TRS/CSI-RS associated with the current beam is determined.

UE根据当前波束的波束信息,确定当前波束所关联的共享TRS/CSI-RS。The UE determines the shared TRS/CSI-RS associated with the current beam according to the beam information of the current beam.
示例性的,UE根据当前波束的波束信息的SSB的索引和/或QCL参数,从信号配置信息中,确定出SSB的索引和/或QCL参数对应的共享TRS/CSI-RS。Exemplarily, the UE determines the shared TRS/CSI-RS corresponding to the SSB index and/or the QCL parameter from the signal configuration information according to the SSB index and/or the QCL parameter of the beam information of the current beam.
如此,UE基于波束信息与共享TRS/CSI-RS的对应关系,确定当前波束对应的共享TRS/CSI-RS,提高确定当前波束对应的共享TRS/CSI-RS的准确性。In this way, the UE determines the shared TRS/CSI-RS corresponding to the current beam based on the correspondence between the beam information and the shared TRS/CSI-RS, and improves the accuracy of determining the shared TRS/CSI-RS corresponding to the current beam.
在一个实施例中,所述共享TRS/CSI-RS至少用于供空闲态UE和/或非激活态UE针对与所述共享TRS/CSI-RS关联的波束的同步。In one embodiment, the shared TRS/CSI-RS is used at least for synchronization of idle UEs and/or inactive UEs for beams associated with the shared TRS/CSI-RS.

UE确定当前波束关联的共享TRS/CSI-RS后,响应于UE检测到当前波束关联的共享TRS/CSI-RS,UE可以采用共享TRS/CSI-RS进行同步或无线信号测。After the UE determines the shared TRS/CSI-RS associated with the current beam, in response to the UE detecting the shared TRS/CSI-RS associated with the current beam, the UE may use the shared TRS/CSI-RS for synchronization or radio signal measurement.
这里,无线信号测量可以是RRM测量。Here, the wireless signal measurement may be an RRM measurement.
响应于UE确定当前波束具有关联的共享TRS/CSI-RS,UE可以不再使用SSB进行同步或无线信号测量。由于相关技术中,UE需要采用3个SSB 周期进行同步;而本公开实施例的技术方案采用共享TRS/CSI-RS进行同步,只需要一个SSB周期。因此,采用共享TRS/CSI-RS同步可以减少UE唤醒时间,降低UE的功耗。In response to the UE determining that the current beam has an associated shared TRS/CSI-RS, the UE may no longer use the SSB for synchronization or radio signal measurements. Because in the related art, the UE needs to use 3 SSB cycles for synchronization; while the technical solutions of the embodiments of the present disclosure use shared TRS/CSI-RS for synchronization, and only one SSB cycle is required. Therefore, the use of shared TRS/CSI-RS synchronization can reduce the wake-up time of the UE and reduce the power consumption of the UE.
响应于UE确定当前波束具有关联的共享TRS/CSI-RS,UE也可以使用SSB进行同步或无线信号测量。The UE may also use the SSB for synchronization or radio signal measurements in response to the UE determining that the current beam has an associated shared TRS/CSI-RS.

For example, the validation indication may be carried in the signal configuration information.
生效指示可以指示信号配置信息所配置的共享TRS和/或CSI-RS关联的波束的波束信息是否生效。如果生效,UE可以基于信号配置信息确定不同共享TRS和/或CSI-RS关联的波束的波束信息;否则,UE不再基于信号配置信息确定不同共享TRS和/或CSI-RS关联的波束的波束信息。The validation indication may indicate whether the beam information of the beam associated with the shared TRS and/or CSI-RS configured by the signal configuration information is valid. If it takes effect, the UE may determine the beam information of the beams associated with different shared TRS and/or CSI-RS based on the signal configuration information; otherwise, the UE will no longer determine the beams of the beams associated with different shared TRS and/or CSI-RS based on the signal configuration information information.
