US 2025/0158689 A1 · Uplink Beam Indication with Unified TCI Framework

Abstract

Apparatuses, systems, and methods for uplink beam indication with unified TCI framework, including systems, methods, and mechanisms for supporting dynamic switching between single-TRP and multi-TRP transmission for PUCCH, dynamic switching between single-DCI and multi-DCI operation for PUSCH, and to provide a beam indication for SRS for non-codebook transmission with regard to an indicated unified TCI and associated CS-RS as well as selection of a beam to transmit SRS.

Dependent claims

A method for supporting dynamic switching between single transmit receive point (TRP) operation and multi-TRP operation for unified transmission configuration indicator (TCI) for physical uplink channel signaling, comprising:

a user equipment device (UE),
receiving, from a base station, an indication for beam selection for an uplink transmission;
determining, based on the indication, whether to perform the uplink transmission according to single-TRP or multi-TRP operation;
and
performing the uplink transmission according to the determination.

2 more elements

A processor, comprising:

a memory;
and
processing circuitry in communication with the memory and configured to cause a wireless device to:
receive, from a base station, an indication for beam selection for an uplink transmission;
determine, based on the indication, whether to perform the uplink transmission according to single-TRP or multi-TRP operation;
and
perform the uplink transmission according to the determination.
