REFERENCE SIGNAL RESOURCE SELECTION BASED BEAM PREDICTION

Title:

REFERENCE SIGNAL RESOURCE SELECTION BASED BEAM PREDICTION

Document Type and Number:

WIPO Patent Application WO/2024/007180

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a reference signal resource set that includes a set of reference signal resources associated with a time division multiplexing (TDM) scheme and a set of spatial precoders. A network entity may use a codebook or an artificial intelligence (AI) model to determine the SRI. The UE may transmit reference signals using the reference signal resources and according to the TDM scheme and using the spatial precoders. The UE may receive a message including a sounding reference signal (SRS) resource indicator (SRI) indicating at least two reference signal resources, which may correspond to a set of beams predicted by the network entity. The SRI may include a linear combination of the reference signal resources. The UE may transmit an uplink message using an uplink transmission beam based on the set of beams.
