Title:
APPARATUS AND METHODS OF SIMULTANEOUS UE RX BEAM REFINEMENT
Document Type and Number:
WIPO Patent Application WO/2022/027446
Kind Code:
A1
Abstract:
Apparatus and methods of enhanced CSI-RS resource configuration and transmission for simultaneous UE Rx beam refinement are disclosed. The apparatus includes: a receiver that receives Channel State Information Reference Signal (CSI-RS) configuration comprising one or more CSI-RS resource sets for Receive (Rx) beam refinement, the CSI-RS resource sets comprising a plurality of CSI-RS resources for transmission of a plurality of CSI-RSs that are Frequency-Division Multiplexed (FDMed), wherein the receiver further receives, simultaneously, the CSI-RSs based on one or more Quasi Co-Location (QCL) assumptions; a processor that performs a simultaneous Rx beam refinement corresponding to the CSI-RSs that are FDMed; and a transmitter that transmits a reporting according to a Channel State Information (CSI) reporting configuration.
