Title:
REPORTING PRECODING MATRIX INFORMATION FOR MULTIPLE CANDIDATE TRANSMISSION AND RECEPTION POINT GROUPS
Document Type and Number:
WIPO Patent Application WO/2023/216220
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving an indication of a set of transmission-reception point (TRP) groups from a network entity. Upon receiving the indication, the UE may transmit, to the network entity and for each TRP that is included in the set of TRP groups, an indication of one or more respective single-TRP precoding matrix components and transmit, to the network entity and for each TRP group that is included in the set of TRP groups, an indication of one or more respective multi-TRP precoding matrix components. Using a combination of the one or more respective multi-TRP precoding matrix components and the one or more respective single-TRP precoding matrix components, the network entity may determine a precoding matrix for communication with the UE.
