Application: Enhancements of physical channels in multi-trp (Patent ID: US20240214137A1)
The patent filed by InterDigital Inc. describes systems, methods, and instrumentalities for enhancing physical channels in Multi-TRP. The enhancements focus on improving reliability for various channels, such as the physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH). These enhancements include support for control resource set (CORESET) combining, activation/deactivation of repetition combining, resource selection, spatial relation determination and signaling, and configured and dynamic grant enhancements.
The patent's claims detail a wireless transmit-receive unit (WTRU) with a processor that receives downlink control information (DCI) related to uplink scheduling, determines sequences of sounding reference signal resource indicators (SRIs) based on spatial domain information and repetitions, establishes spatial relations for PUSCH repetition transmissions, and sends transmissions accordingly. The claims also cover methods for receiving DCI, determining SRI sequences, establishing spatial relations for PUSCH repetitions, and sending transmissions based on these relations. Additionally, the claims include determining transmit times for the PUSCH repetitions to further enhance reliability and efficiency in wireless communication systems.
