Description

Communication method and related device Technical Field The present application relates to the field of communications, and in particular, to a communication method and related apparatus. Background The beam scanning procedure in the New Radio (NR) combines beam measurement, beam reporting, and beam determination, selects a beam pair between an optimal pair of transceivers, and after determining an optimal transmission beam, the network device may indicate the transmission beam through beam indication information. The beam indication information may be a transmission configuration indication (transmission configuration indicator, TCI) state, which may be used to indicate a quasi co-located (quasi-colocation) relationship between two reference signals. Currently, the network device may configure the TCI state list for the terminal device through high-layer signaling, and the TCI state list may include a plurality of TCI states, for example, the network device configures up to 64 TCI states for each bandwidth part (BWP) in each cell. The network device may then activate one or more of the TCI states via higher layer signaling. The network device may then indicate to the terminal device a selected TCI state by physical layer signaling. For beam management scenarios based on artificial intelligence (ARTIFICIAL INTELLIGENCE, AI), taking terminal-side airspace beam prediction as an example, the terminal device may report information of the predicted K beams, e.g., the index of the top K optimal beams. If the existing TCI indication mechanism is applied, after the terminal device reports the information of the predicted K beams, it may occur that one or more TCI states activated by the network device (for example, the number of activated TCI states is M) does not include K TCI states corresponding to the predicted K beams, and the network device may indicate only one of the activated M TCI states through physical layer signaling, if the network device desires to indicate one of the predicted K beams for transmission, it is necessary to reactivate a set of TCI states including K TCI states corresponding to the predicted K beams through higher layer signaling, and then indicate one of the K TCI states through physical layer signaling. Disclosure of Invention The application provides a communication method and a related device, aiming at reducing time delay and signaling overhead caused by frequently sending activation signaling. In a first aspect, a communication method is provided, which may be applied to a terminal side, for example, a terminal device or a communication module in the terminal device, or a circuit or a chip (such as a modem (modem) chip, also called a baseband (baseband) chip, or a system on chip (SoC) chip or a system in package (SYSTEMIN PACKAGE, SIP) chip) in the terminal device, where the method is applied to the terminal device, and will be described below as an example. The method includes the steps of sending a first report, wherein the first report comprises predicted information of Y downlink signals, the information of the Y downlink signals corresponds to the Y downlink signals, Y is a positive integer less than or equal to K, and receiving first information, wherein the first information is used for indicating first transmission indication information, the first transmission indication information is one of X+M transmission indication information, the X+M transmission indication information corresponds to the Y downlink signals, the remaining M transmission indication information in the X+M transmission indication information is activated transmission indication information, and M is a non-negative integer. K is the upper limit of the number of downlink signals corresponding to the information expected to be predicted or reported. In one possible implementation, K may be configured for the network device or predefined for the protocol, and the terminal device may dynamically determine, according to the prediction result, the number of downlink signals corresponding to the actually reported prediction information, where the number of downlink signals corresponding to the actually reported prediction information may be smaller than K, so that unnecessary reporting overhead may be reduced. The terminal device may report the reports periodically or semi-continuously, each reporting period may report one report, and for at least one report reported by at least one reporting period, the first report is one of the at least one report. Or the network device may trigger reporting of at least one report non-periodically, the first report being one of the at least one report. Or the network device may configure at least one periodic report while triggering at least one non-periodic report, the first report being one of the at least two reports. Each report of the at least one report reported by the terminal device includes information of the predicted at least one downlink signal. According to the
