Description

一种传输配置指示TCI状态切换的方法和通信装置A method and communication device for transmission configuration indication TCI state switching 技术领域technical field
本申请涉及无线通信领域，并且更具体地，涉及一种传输配置指示TCI状态切换的方法和通信装置。The present application relates to the field of wireless communication, and more particularly, to a method and a communication device for transmitting configuration indication TCI state switching.
背景技术Background technique
在某些通信***中，在终端设备与网络设备之间通信时，为了正确接收网络设备发送的信号，网络设备可能会向终端设备指示传输配置指示(Transmission Configuration Indicator，TCI)状态。通过测量与TCI状态相关联的参考信号，终端设备可以获取正确接收网络设备发送信号所需的一些必要特征。In some communication systems, in order to correctly receive the signal sent by the network device during the communication between the terminal device and the network device, the network device may indicate the transmission configuration indicator (TCI) status to the terminal device. By measuring the reference signal associated with the TCI state, the terminal device can obtain some necessary characteristics required to correctly receive the signal sent by the network device.
当终端设备在不同网络设备之间移动时，网络设备可能会指示终端设备进行TCI状态切换，并根据新的TCI状态收发数据。然而，目前TCI状态切换存在着时延较大的问题。When the terminal device moves between different network devices, the network device may instruct the terminal device to switch the TCI state, and send and receive data according to the new TCI state. However, the current TCI state switching has the problem of a large delay.
因此，亟需提出一种降低TCI状态切换时延的方法。Therefore, there is an urgent need to propose a method for reducing the TCI state switching delay.
发明内容SUMMARY OF THE INVENTION
本申请提供一种传输配置指示TCI状态切换的方法和通信装置，当终端设备在不同网络设备之间移动需要进行TCI状态切换时，能够降低TCI状态切换的时延。The present application provides a method and a communication device for indicating TCI state switching by transmission configuration, which can reduce the delay of TCI state switching when a terminal device moves between different network devices and needs to perform TCI state switching.
第一方面，本申请提供一种传输配置指示TCI状态切换的方法。该方法可以由终端设备执行，或者也可以由配置于终端设备中的芯片执行，本申请对此不作限定。In a first aspect, the present application provides a method for transmitting configuration indication TCI state switching. The method may be executed by a terminal device, or may also be executed by a chip configured in the terminal device, which is not limited in this application.
具体地，该方法包括：终端设备接收第一指示信息，所述第一指示信息用于指示所述TCI状态对应的第一时长集合，所述第一时长集合包括一个或多个切换时长，所述第一时长集合根据第二时长集合获得，所述第二时长集合包括一个或多个切换时长，所述第二时长集合由终端设备上报给网络设备；根据所述第一时长集合中的第一切换时长，切换所述TCI状态。Specifically, the method includes: the terminal device receives first indication information, where the first indication information is used to indicate a first duration set corresponding to the TCI state, the first duration set includes one or more handover durations, and the The first duration set is obtained according to the second duration set, the second duration set includes one or more handover durations, and the second duration set is reported by the terminal device to the network device; according to the first duration set in the first duration set. For a switching duration, the TCI state is switched.
可见，通过上述方法，当终端设备在不同网络设备之间移动需要进行TCI状态切换时，通过接收网络设备发送的第一指示信息指示的第一时长集合中的第一切换时长，进而终端设备根据第一切换时长切换TCI状态，能够降低TCI状态切换的时延。It can be seen that, through the above method, when the terminal device needs to perform TCI state switching when moving between different network devices, the terminal device receives the first switching duration in the first duration set indicated by the first indication information sent by the network device, and then the terminal device according to the The first switching duration switches the TCI state, which can reduce the delay of the TCI state switching.

为便于理解本申请实施例，首先对本申请中涉及的几个术语做简单说明。In order to facilitate the understanding of the embodiments of the present application, firstly, several terms involved in the present application are briefly described.
1、传输配置指示(transmission configuration indicator，TCI)状态：TCI状态用于指示数据传输过程的信道大尺度参数与一个或两个下行参考信号的准共置(quasi co-location,QCL)关系。从而，终端能够基于该TCI状态，获知所接收信号的信道大尺度参数关系的指示信息，进而基于信道估计，解调出信号携带的数据。每个TCI状态中可以包括服务小区的索引(ServeCellIndex)、带宽部分(band width part，BWP)标识(identifier，ID)和参考信号资源标识。1. Transmission configuration indicator (TCI) state: The TCI state is used to indicate the quasi co-location (QCL) relationship between the large-scale channel parameters of the data transmission process and one or two downlink reference signals. Therefore, based on the TCI state, the terminal can obtain the indication information of the channel large-scale parameter relationship of the received signal, and then demodulate the data carried by the signal based on the channel estimation. Each TCI state may include a serving cell index (ServeCellIndex), a bandwidth part (bandwidth part, BWP) identifier (identifier, ID), and a reference signal resource identifier.
2、准共址(quasi co-located，QCL)：准共址QCL关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征。例如，如果两个天线端口具有准共址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。具有准共址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准共址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。其中，所述参数可以包括以下一项或多项信道大尺度参数：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括发射角(Angle of arrival，AOA)、主发射角(Dominant  AoA)、平均到达角(Average AoA)、到达角(Angle of departure，AOD)、信道相关矩阵，到达角的功率角度扩展谱，平均触发角(Average AoD)、出发角的功率角度扩展谱、发射信道相关性、接收信道相关性、发射波束成型、接收波束成型、空间信道相关性、空间滤波器，或，空间滤波参数，或，空间接收参数等中的一项或多项。2. Quasi co-located (QCL): A quasi co-located QCL relationship is used to indicate that multiple resources have one or more identical or similar communication characteristics. For example, if two antenna ports have a quasi-co-located QCL relationship, then the large-scale characteristics of the channel carrying a signal at one port can be inferred from the large-scale characteristics of the channel carrying a signal at the other port. Signals corresponding to antenna ports with a quasi-co-located QCL relationship have the same parameters, or the parameters of one antenna port can be used to determine the parameters of another antenna port with a quasi-co-located QCL relationship with that antenna port, or, two The antenna ports have the same parameters, or the parameter difference between the two antenna ports is smaller than a certain threshold. The parameters may include one or more of the following large-scale channel parameters: delay spread, Doppler spread, Doppler shift, average delay delay), average gain, spatial Rx parameters. Among them, the spatial receiving parameters may include the angle of arrival (Angle of arrival, AOA), the main angle of arrival (Dominant AoA), the average angle of arrival (Average AoA), the angle of arrival (Angle of departure, AOD), the channel correlation matrix, the angle of arrival Power Angle Spread Spectrum, Average AoD, Power Angle Spread Spectrum at Departure Angle, Transmit Channel Correlation, Receive Channel Correlation, Transmit Beamforming, Receive Beamforming, Spatial Channel Correlation, Spatial Filter, or, One or more of spatial filtering parameters, or, spatial receiving parameters, etc.
3、时长：例如但不限于，可以是符号、帧、子帧、半帧、***帧、时隙slot、迷你时隙、无线帧或传输时间间隔(Transmission time interval，TTI)等，本申请实施例并不限定。另外，时长也可以有其它的名称，比如时刻、时间、时段、时延等。3. Duration: For example, but not limited to, it can be a symbol, frame, subframe, half frame, system frame, time slot, mini-slot, radio frame or transmission time interval (Transmission time interval, TTI), etc., this application implements Examples are not limited. In addition, the duration may also have other names, such as time, time, period, delay, and the like.
4、第一预设时长：为网络设备根据网络设备和终端设备的某些参数计算获得的最大TCI状态的切换时间。4. The first preset duration: the switching time of the maximum TCI state calculated and obtained by the network device according to certain parameters of the network device and the terminal device.
示例性的，如图3所示，网络设备为终端设备配置多个TCI状态，在发送媒体接入控制元素(Media access control element，MAC-CE)命令之前，只有TCI#0是激活的，TCI#1是已知但未激活的。网络在某一时刻(n)发送MAC-CE TCI状态切换命令，激活TCI#1。终端设备可以在收到该命令并发送混合自动重传请求(hybrid automatic repeat request，HARQ)反馈后的3ms内继续基于原TCI状态(TCI#0)收发数据。一段时间后，终端设备可以在n+T HARQ+3ms+T first-SSB+T SSB-proc时刻开始基于新TCI状态(TCI#1)收发数据。 Exemplarily, as shown in FIG. 3 , the network device configures multiple TCI states for the terminal device, and before sending a media access control element (Media access control element, MAC-CE) command, only TCI#0 is activated, and the TCI #1 is known but not activated. The network sends a MAC-CE TCI state switching command at a certain time (n) to activate TCI#1. The terminal device can continue to send and receive data based on the original TCI state (TCI#0) within 3ms after receiving the command and sending a hybrid automatic repeat request (HARQ) feedback. After a period of time, the terminal device can start sending and receiving data based on the new TCI state (TCI#1) at the moment of n+T HARQ +3ms+T first-SSB +T SSB-proc .
其中，T HARQ为发送TCI状态切换命令到发送HARQ反馈的时间。对于物理下行共享信道(physical downlink shared channel，PDSCH)，终端设备需要对每一个slot的数据进行反馈，指示该数据是否正确接收； Wherein, T HARQ is the time from sending the TCI state switching command to sending the HARQ feedback. For the physical downlink shared channel (PDSCH), the terminal device needs to feed back the data of each slot, indicating whether the data is received correctly;
3ms为MAC-CE处理时间；3ms is the MAC-CE processing time;
T first-SSB为终端设备完成MAC-CE解码后，在上述T HARQ+3ms后，需要继续等待到第一个SSB到来的时间； After T first-SSB completes MAC-CE decoding for the terminal device, after the above-mentioned T HARQ +3ms, it needs to continue to wait until the arrival of the first SSB;
T SSB-proc为收到SSB后处理的时间。 T SSB-proc is the processing time after receiving the SSB.
在本申请实施例中，若TCI状态对应的第一切换时长小于第一预设时长，则终端设备根据第一切换时长切换TCI状态；若TCI状态对应的第一切换时长大于第一预设时长，则终端设备根据第一预设时长切换TCI状态。结合图3，第一预设时长可以为T first-SSB+T SSB-proc。 In this embodiment of the present application, if the first switching duration corresponding to the TCI state is less than the first preset duration, the terminal device switches the TCI state according to the first switching duration; if the first switching duration corresponding to the TCI state is greater than the first preset duration , the terminal device switches the TCI state according to the first preset duration. With reference to FIG. 3 , the first preset duration may be T first-SSB+ T SSB-proc .

目前，在终端设备与网络设备之间通信时，为了正确接收网络设备发送的信号，网络设备可能会向终端指示TCI状态。通过测量与TCI状态相关联的参考信号，终端设备可以获取正确接收网络设备发送信号所需的一些必要特征。当终端设备在不同网络设备之间移动时，网络设备可能会指示终端设备进行TCI状态切换，并根据新的TCI状态收发数据。然而，目前TCI状态切换存在着时延较大的问题。因此，亟需提出一种降低TCI状态切换时延的方法。At present, during communication between a terminal device and a network device, in order to correctly receive a signal sent by the network device, the network device may indicate the TCI status to the terminal. By measuring the reference signal associated with the TCI state, the terminal device can obtain some necessary characteristics required to correctly receive the signal sent by the network device. When the terminal device moves between different network devices, the network device may instruct the terminal device to switch the TCI state, and send and receive data according to the new TCI state. However, the current TCI state switching has the problem of a large delay. Therefore, there is an urgent need to propose a method for reducing the TCI state switching delay.
有鉴于此，本申请提供一种TCI状态切换的方法，通过该方法能够降低TCI状态切换时延。In view of this, the present application provides a TCI state switching method, by which the TCI state switching delay can be reduced.
以下结合图4阐述本申请实施例提供的TCI状态切换的方法。需要说明的是，本申请提供的TCI状态切换的方法可以应用于无线通信***中，例如，图1中所示的通信***100中。处于通信***中的通信装置之间可具有无线通信连接关系。例如，图1中所示的终端设备121和122分别可以与网络设备111之间具有无线通信连接关系，本申请实施例对此不作限定。The following describes the TCI state switching method provided by the embodiment of the present application with reference to FIG. 4 . It should be noted that the TCI state switching method provided by the present application can be applied to a wireless communication system, for example, the communication system 100 shown in FIG. 1 .
