UPLINK SINGLE FREQUENCY NETWORK OPERATION IN UNIFIED TRANSMISSION CONFIGURATION INDICATION FRAMEWORK

Title:

UPLINK SINGLE FREQUENCY NETWORK OPERATION IN UNIFIED TRANSMISSION CONFIGURATION INDICATION FRAMEWORK

Document Type and Number:

WIPO Patent Application WO/2023/220960

Kind Code:

A1

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling enabling uplink communications with a network via a first transmission and reception point (TRP) using a first set of antenna elements of the UE and via a second TRP using a second set of antenna elements of the UE during a same set of time and frequency resources according to a single frequency network (SFN) configuration. The control signaling may include a set of parameters enabling the uplink communications with the network via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH). The control signaling may also include a control resource set including an indication for the UE to transmit according to a SFN transmission scheme. The UE may transmit according to the SFN configuration, the uplink communications to the network via the first TRP and the second TRP.
