Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

Provided in the disclosure are a method for determining uplink transmission parameters and a method for transmitting configuration information. The method includes: receiving indication information transmitted from a network side; and determining uplink transmission parameters on the basis of the indication information. Also provided in the disclosure are a device for determining uplink transmission parameters and a device for transmitting configuration information, and a storage medium. The disclosure solves the problem in which a terminal cannot determine uplink transmission parameters in a variety of complicated antenna configurations, thus achieving the effect of effectively reduced overhead.
