Abstract: This application provides a method. The method may include: a transmit-side device determines frequency-domain positions of reference signals that are used for phase noise estimation and that are on a plurality of resource blocks, where there are a plurality of reference signals on at least one resource block in the plurality of resource blocks, the reference signals occupy consecutive frequency-domain resources on the at least one resource block, for example, occupy a plurality of consecutive subcarriers; the transmit-side device maps, based on the frequency-domain positions of the reference signals on the plurality of resource blocks, the reference signals to one or more symbols, and sends, to a receive-side device, the one or more symbols to which the reference signals are mapped; and the receive-side device performs phase noise estimation based on the reference signals.

Abstract: The present disclosure relates to beam configuration methods. In one example method, a terminal device receives a first beam from a network device, where an identifier of a reference signal sent on the first beam is a first identifier. The terminal device configures a receive beam corresponding to the first beam based on a spatial reception parameter corresponding to a downlink synchronization signal associated with current measurement, where before receiving the first beam, the terminal device does not measure or report a second beam corresponding to the first identifier.

Abstract: A method includes a first module of a terminal device sends a first request message to a second module, obtains first information from the second module, and assists cell handover based on a first cell handover list. The first request message is used to request the first cell handover list corresponding to a first TAC, which is a TAC of a current cell of the terminal device, and the first information indicates the first cell handover list. The terminal device may store a cell list corresponding to each line in advance. When the terminal device moves on a line, the terminal device may determine, based on the first TAC, the cell list corresponding to the line to perform cell handover.

Abstract: A communication method includes a terminal device having a dual-card function that obtains, passing through a target section and from a network device, network status information of the target section through which the terminal device is about to pass, and determines, in advance based on the network status information, a target subscriber identity module (SIM) card used when the terminal device passes through the target section. Subsequently, before or when the terminal device passes through the target section, the terminal device can switch to the target SIM card in advance for communication.

Abstract: Embodiments of this disclosure provide a channel state feedback method and apparatus. The method includes: A terminal device receives first indication information from a network device. The terminal device reduces a first value of first information to a second value based on the first indication information. The second value is used to determine channel state feedback information. The first information includes channel state indicator CQI information or signal-to-interference-plus-noise ratio SINR information. The channel state feedback information determined based on the second value is more accurate than channel state feedback information determined based on the first value. This can improve accuracy of the channel state feedback information.

Abstract: A data caching method is applied to a first terminal comprising an application processor and a modem processor. The method includes the application processor sending preset path information of a first route to the modem processor, where the preset path information includes a node handover list of the first route, the node handover list includes information about a plurality of nodes, each node corresponds to at least one cell, and information about each node includes a node identifier, a network performance identifier of the node, and a cell identifier corresponding to the node. The modem processor sends first indication information to the application processor, where the first indication information is used to indicate the application processor to cache data, and the first indication information is determined based on the preset path information.
