TRP-Specific PUSCH Transmissions for Multi-TRP Operation - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464419 titled 'TRP-Specific PUSCH Transmissions for Multi-TRP Operation

Simplified Explanation

The patent application describes a system where a user equipment (UE) can communicate with multiple transmission and reception points (TRPs). The UE receives a configuration for a sounding reference signal (SRS) resource set, which includes two resource sets corresponding to two different TRPs. The UE also receives a downlink control information (DCI) transmission that includes an SRS resource indicator (SRI). The SRI indicates which resource from each resource set should be selected for a physical uplink shared channel (PUSCH) transmission to each TRP. The UE then transmits the PUSCH transmissions to the respective TRPs based on the SRI.

• The patent application introduces a system for a UE to communicate with multiple TRPs.
• The UE receives a configuration for SRS resource sets corresponding to each TRP.
• The UE receives a DCI transmission that includes an SRI indicating which resource from each resource set should be selected for PUSCH transmissions.
• The UE transmits the PUSCH transmissions to the respective TRPs based on the SRI.

Potential Applications

• This technology can be applied in wireless communication systems where a UE needs to communicate with multiple TRPs simultaneously.
• It can be used in scenarios where there is a need for efficient resource allocation for PUSCH transmissions to different TRPs.

Problems Solved

• The system solves the problem of efficiently allocating resources for PUSCH transmissions to multiple TRPs.
• It addresses the challenge of coordinating and managing simultaneous communications with multiple TRPs.

Benefits

• The technology allows for improved efficiency in resource allocation for PUSCH transmissions.
• It enables effective communication with multiple TRPs, enhancing overall system performance.
• The system provides flexibility in selecting and transmitting PUSCH transmissions to different TRPs based on the SRI.

Original Abstract Submitted

A user equipment (UE) is configured to communicate with one or more transmission and reception points (TRPS). The UE receives a sounding reference signal (SRS) resource set configuration including a first resource set corresponding to a first transmission and reception point (TRP) and a second resource set corresponding to a second TRP, receives a downlink control information (DCI) transmission including an SRS resource indicator (SRI) indicating (i) which resource from the first resource set should be selected for a first physical uplink shared channel (PUSCH) transmission to a first TRP, and (ii) which resource from the second resource set should be selected for a second PUSCH transmission to a second TRP and transmits the first PUSCH transmission to the first TRP and the second PUSCH transmission to the second TRP.
