US 2025/0167968 A1 · Unified Transmission Configuration Indication (TCI) States

Abstract

A method is performed by a communication device (12) configured for use in a communication network (10) is disclosed. The communication device (12) receives, for each of one or more uplink channels or signals (20), a configuration (24) that indicates with which of multiple activated unified transmission configuration indication, TCI, states (16) the uplink channel or signal (20) is associated. In some embodiments, the communication device (12) determines, for each of the one or more uplink channels or signals (20), a spatial filter for the uplink channel or signal (20) based on one or more activated unified TCI states (16) that are associated with the uplink channel or signal (20) according to the configuration (24) received for that uplink channel or signal (20). The communication device (12) may then transmit the one or more uplink channels or signals (20) using the one or more spatial filters determined for the one or more uplink channels or signals (20).
