Abstract: Embodiments of this application disclose a resource allocation method, a base station, and a terminal. The method includes: A base station sends a configuration message to a terminal, where the configuration message is used to configure, for the terminal, a random access channel RACH resource used in a channel occupancy time COT. The base station receives a random access request that is sent by the terminal based on the RACH resource allocated by using the configuration message. According to embodiments of this application, a random access latency of the terminal can be reduced.

Abstract: Example transmission methods and apparatus are described. One example method includes: determining, by a network device, downlink control information (DCI), wherein the DCI includes a first request field. The first request field indicates sending reference signal from the network device to a terminal device, and the first request field triggers the terminal device to report a measurement result of the reference signal to the network device. The measurement result includes channel state information (CSI) and/or beam state information (BSI). The DCI is sent by the network device to the terminal.
