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

This abstract first appeared for US patent application 18462734 titled 'TRP-Specific PUSCH Transmissions for Multi-TRP Operation

Simplified Explanation

The abstract describes a patent application for a user equipment (UE) that 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, which includes an SRS resource indicator (SRI) that specifies which resource from each resource set should be used for transmitting data to each TRP. The UE then transmits the data to the respective TRPs based on the SRI.

• The patent application describes a method for a UE to communicate with multiple TRPs.
• The UE receives a configuration for SRS resource sets, which are used for transmitting data to the TRPs.
• The UE also receives a DCI transmission that includes an SRI, indicating which resource from each resource set should be used for transmitting data to each TRP.
• Based on the SRI, the UE transmits the data to the respective TRPs.

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 multiple TRPs are deployed to provide better coverage or capacity in a specific area.

Problems Solved

• The technology solves the problem of efficiently transmitting data to multiple TRPs using SRS resource sets.
• It allows the UE to select the appropriate resources from each set based on the SRI, ensuring reliable and optimized communication with each TRP.

Benefits

• The technology enables efficient and optimized communication between a UE and multiple TRPs.
• It improves the overall performance and reliability of the wireless communication system.
• It allows for better utilization of available resources and enhances the user experience.

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.
