Title:
UE-ASSISTED SINGLE FREQUENCY NETWORK (SFN) MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2022/000133
Kind Code:
A1
Abstract:
Aspects of the disclosure relate to radio access networks with a capability to dynamically reconfigure a number of transmission-reception points (TRPs) in a single-frequency network (SFN) based on channel measurements. In one example, a mobile device receives a configuration message including a plurality of transmission configuration indicator (TCI) states, and potentially further including an indication identifying one or more of the TCI states as main TCI states. The message may further include an indication that it includes the plurality of TCI states. The UE receives a downlink traffic channel and demodulates the traffic channel based on only a subset of the TCI states (e.g., the main TCI state (s) ). The UE further measures one or more channel parameters corresponding to each TCI state of the plurality of TCI states, and transmits a channel state information report based on the channel parameters. Other aspects, embodiments, and features are also claimed and described.
