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

This abstract first appeared for US patent application 17754460 titled 'TRP-Specific PUSCH Transmissions for Multi-TRP Operation

Simplified Explanation

The abstract of this patent application describes a configuration for a user equipment (UE) to communicate with one or more transmission and reception points (TRPs). The UE receives a sounding reference signal (SRS) resource set configuration, which includes a first resource set for a first TRP and a second resource set for a second TRP. The UE also receives a downlink control information (DCI) transmission, which includes an SRS resource indicator (SRI) indicating which resource from the first resource set should be selected for a first physical uplink shared channel (PUSCH) transmission to the first TRP, and which resource from the second resource set should be selected for a second PUSCH transmission to the second TRP. The UE then transmits the first PUSCH transmission to the first TRP and the second PUSCH transmission to the second TRP.

  • The patent application describes a method for configuring a UE to communicate with multiple TRPs.
  • The UE receives a configuration for SRS resource sets corresponding to different TRPs.
  • The UE receives a DCI transmission indicating which resources from the SRS resource sets should be selected for PUSCH transmissions.
  • The UE transmits the PUSCH transmissions to the corresponding TRPs.

Potential applications of this technology:

  • This technology can be applied in wireless communication systems where a UE needs to communicate with multiple TRPs simultaneously.
  • It can be used in cellular networks to improve coverage and capacity by utilizing multiple TRPs.

Problems solved by this technology:

  • This technology solves the problem of efficiently configuring a UE to communicate with multiple TRPs.
  • It addresses the challenge of selecting the appropriate resources for PUSCH transmissions to different TRPs.

Benefits of this technology:

  • By allowing a UE to communicate with multiple TRPs, this technology improves the overall performance and reliability of wireless communication.
  • It enables better utilization of available network resources and enhances the capacity of the system.
  • This technology provides flexibility in selecting the appropriate resources for PUSCH transmissions, optimizing the transmission quality.


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.
