US 12,191,974 B2 · Multi transmission reception point (TRP) system and method thereof

Abstract

A multi Transmission Reception Point (TRP) system is provided. The system includes a User Equipment (UE), a core network, a plurality of cells, and a Transmission Reception Point (TRP) controller (TRP-C). The core network is defined by a Centralized or Cloud Radio Access Network (C-RAN). The plurality of cells where each of which is connected to the UE. Each cell includes at least one TRP of a number of TRPs. The TRP-C is connected to the core network, or cloud network or virtual network and to at least one TRP of the number of TRPs in each cell of the plurality of cell. The TRP-C is configured to determine the number of TRPs required for each cell of the plurality of cells to serve the UE.

Dependent claims

A transmission reception point (TRP) controller (TRP-C) entity in a TRP system, the TRP-C entity comprising:

a transceiver;
a processor coupled with the transceiver;
and
memory storing instructions that, when executed by the processor, cause the TRP-C entity to:
connect a plurality of cells to a User Equipment (UE),
determine a number of TRPs for each cell of the plurality of cells to serve the UE, and
form a cell topology for each cell of the plurality of cells based on the determined number of TRPs for each cell,
wherein the TRP-C entity is connected to a core network, the core network being defined by a centralized or cloud radio access network (C-RAN).
