Provided is a method for a first device to perform sidelink communication with a second device. The method comprises: determining a first resource for a first sidelink transmission; receiving, from a third device, a SCI including information related to a second resource for a second sidelink transmission; determining to reselect the first resource, based on overlap of the first resource and the second resource and a relationship between a first priority value of the first sidelink transmission and a second priority value of the second sidelink transmission satisfying a pre-configured condition; and transmitting, to the second device, a first PSCCH related to the first sidelink transmission or a first PSSCH related to the first PSCCH, based on a third resource determined by reselecting the first resource, wherein the pre-configured condition includes a condition in which the first priority value is greater than the second priority value.

A relay user equipment (UE) device transmits selected system information in a sidelink discovery message where the selected system information is a subset of system information received from a cell at the relay UE device. A remote UE device receiving the sidelink discovery message with the selected system information obtains at least system information for accessing the cell where such system information may not be available directly from the cell. The remote UE receiving select system information from each of a plurality of candidate relay UE devices manages relay selection/reselection at least partially based on the selected system information.

Techniques of generating CSI reports include designating at least one of the reports as a reference and the other reports as dependent on the reference. For example, a dependent CSI report may have a differential value of a CSI quantity rather than a raw value of the CSI quantity. Because generally for parameters in a CSI report, the differential quantity has a smaller range of values than the raw values of the CSI quantity, a quantization of the differential value of the CSI quantity will have fewer bits than the raw value; for example, for L1-RSRP, the raw value has 7 bits while the differential value has 4 bits. In another example, a dependent value of a CSI quantity is a flag indicating that the CSI quantity value is located in a reference CSI report.

The method includes: a first electronic device detects signal strength existing when the first electronic device communicates with a second electronic device, and determines whether the signal strength is less than a preset value; when the signal strength is less than the preset value, the first electronic device determines a current service state of the second electronic device, and determines, based on the current service state, working modes that respectively correspond to the first electronic device and the second electronic device and that are suitable for the current service state; and the first electronic device switches a working mode to the determined working mode that corresponds to the first electronic device and that is suitable for the current service state, and sends an instruction to indicate the second electronic device to switch a working mode to the determined working mode that corresponds to the second electronic device.

Embodiments of this application provide a channel matrix determining method, an apparatus, and a system, relating to the field of communication technologies, to resolve a technical problem that a manner in which a network device determines a precoding matrix based on an existing PMI indicator is not applicable to long-distance communication. The method includes: A terminal device obtains a plurality of reference signals, determines a first channel matrix based on the plurality of reference signals, and feeds back, to a network device, first information indicating some channel elements in the first channel matrix. The terminal device may further receive a downlink signal determined based on the first information and sent by the network device. A channel element in the some channel elements is determined based on signal strength and/or a time-frequency resource of the reference signal.
