US 2026/0019221 A1 · UNIFIED TCI FRAMEWORK EXTENSION FOR mTRP-BASED OPERATION IN WIRELESS COMMUNICATION

Abstract

Processes and systems for a unified transmission configuration indication (TCI) framework extension for multi-transmission and reception point (TRP) operation in wireless communication networks. For a unified TCI-state extension from sTRP to mTRP the system is configured to support switching between a single TRP (sTRP) mode operation and an mTRP mode operation. For a unified TCI-state extension from sTRP to mTRP the system is configured to support up to 4 TCI-states for association with a single TCI codepoint.

Claims20

Dependent claims

A method comprising:

transmitting, to a device, configuration data including a transmission configuration indicator (TCI) field that describes one or more TCI states for at least one cell of a communication network;
receiving, from the device, information indicating a transmission and reception point (TRP) mode of the device, the TRP mode being a single TRP (sTRP) mode or a multi-TRP (mTRP) mode, wherein a cell of a wireless communication network in which the information is being received is operating in the TRP mode.

Dependencies are inferred from the claim text.
