Title:
REFERENCE SIGNALING OVERHEAD REDUCTION APPARATUS AND METHODS
Document Type and Number:
WIPO Patent Application WO/2021/037131
Kind Code:
A1
Abstract:
Network equipment receives, from a User Equipment (UE), an indication that the network equipment is to transition to sparse reference signaling for the UE, and the network equipment then transmits the sparse reference signaling to the UE. The sparse reference signaling is consistent with a sparse signaling pattern, which is determined at the UE based on previous reference signaling previously transmitted to the UE or another UE. At a UE, the sparse reference signaling is received from network equipment, and channel measurement and prediction are performed based on the received sparse reference signaling.
