The present disclosure provides a time domain resource configuration method and a terminal. The method includes: obtaining configuration information of a physical random access channel (PRACH); where the configuration information includes a first configuration value, and the first configuration value is used to indicate a configuration number of PRACH slots in each target time domain granularity; determining distribution of the PRACH slots in the target time domain granularity according to the configuration information; and determining validity of PRACH occasions in the PRACH slots.

Time domain resource configuration method and terminal

A reference signal transmission method and a reference signal transmission device are provided. The reference signal transmission method for a V2X system includes: receiving, by a first device, a first reference signal transmitted by another device via a sidelink; and performing, in accordance with the first reference signal transmitted by the other device, at least two of: a resource occupancy sensing process, an Automatic Gain Control (AGC) process, a Frequency Offset Estimation (FOE) process, a Channel State Information (CSI) measurement process, and a channel estimation process.

Reference signal transmission method and device

The present disclosure provides a transmission feedback method and a UE. The transmission feedback method includes: transmitting a time-frequency transmission resource for transmitting feedback information for unicasting or multicasting transmission to at least one target UE which has established a connection with a source UE; acquiring the feedback information transmitted on the time-frequency transmission resource from the target UE; and determining a unicasting or multicasting transmission state in accordance with the feedback information.
