Abstract: This application describes a resource indication method and a communications device. A resource indication method may include sending, by a first device, first indication information to a second device in an nth time unit, where the first indication information indicate a first time domain resource of a first link or a second link in an (n+k0)th time unit to an (n+k1)th time unit. In the method, the first link is a link between the first device and the second device, the second link is a link between the second device and a third device, k0 is an integer greater than or equal to 0 and less than or equal to k1, and k1 is an integer.

Abstract: Example uplink reference signal sending methods and apparatus are described. One example method includes sending signaling to a terminal device by an access network device. The terminal device determines a sequence type of an uplink reference signal based on the signaling. The terminal device determines transmit power of the uplink reference signal based on the sequence type of the uplink reference signal, and sends the uplink reference signal by using the transmit power of the uplink reference signal.
