REFERENCE RESOURCE INDICATION TECHNIQUES IN WIRELESS COMMUNICATIONS

WIPO Patent Application WO/2019/141147

A1

Methods, systems, and devices for wireless communications are described. One or more reference signals may be transmitted by a user equipment (UE) that may be used by a base station for channel estimation and determination of one or more parameters to be used for subsequent uplink transmission of the UE. The base station may transmit an indication of uplink transmission parameters in an uplink grant that is transmitted to the UE. The UE may modify one or more subsequent reference signal transmissions based on the uplink grant received from the base station and a timing of the uplink grant relative to the one or more subsequent reference signal transmissions. The base station may determine a timing for the uplink grant based on a timing associated with the reference signal transmissions from the UE.
