Abstract: Disclosed are a signal sending method, a priority configuration method, and a device. The signal sending method includes: determining that S signals overlap in time domain; determining M signals in the S signals based on a maximum transmit power of a terminal device and priorities of the S signals, where the S signals include n sidelink signals and k uplink signals, n is a positive integer, k is an integer greater than or equal to 0, a total transmit power of the M signals is less than or equal to the maximum transmit power, and M is a positive integer; and sending the M signals. In embodiments of this application, a plurality of sidelink signals may be simultaneously sent, or a sidelink signal and an uplink signal may be simultaneously sent, thereby resolving a problem that currently a sidelink signal and an uplink signal cannot be simultaneously sent.

Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, or transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.

Abstract: The present invention provides a signal measurement method and apparatus, where the method includes: receiving, by user equipment UE, a measurement configuration message sent by a base station, where the measurement configuration message is used to indicate a reference signal type; performing, by the UE according to the reference signal type indicated by the measurement configuration message, signal quality measurement on a cell to obtain a measurement result; and sending, by the UE, the measurement result to the base station. The method provided in embodiments of the present invention is used to resolve a technical problem in the prior art that normal communication of UE cannot be ensured because RSRP and/or RSRQ of neighboring cells cannot be measured based on an existing reference signal when the neighboring cells use different carrier types.

Abstract: Example information transmission methods, terminal devices, and access network devices are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) partly overlap or completely overlap in time domain. The N pieces of UCI include at least one piece of beam channel quality information and at least one of a piece of channel state information or an acknowledgement (ACK)/a negative acknowledgement (NACK). A priority of the beam channel quality information is higher than a priority of the channel state information, and/or lower than a priority of the ACK/NACK.
