TRACKING REFERENCE SIGNAL TECHNIQUES IN WIRELESS COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described for joint communications among a UE and multiple transmission-reception points (TRPs) in which a subset of the multiple TRPs transmit periodic tracking reference signals (TRSs) for use in measurement and beam management at the UE and the multiple TRPs. The subset of TRPs may include TRPs having a relatively large contribution to signals received at the UE, and may transmit periodic (or semi-persistent) TRSs to be measured at the UE. One of the TRPs may provide configuration information to the UE of which TRPs are included in the subset of TRPs, or the UE may determine which TRPs are included in the subset of TRPs based on a signal quality of transmissions associated with each TRP.
