UNICAST MEASUREMENT AND DETERMINATION FOR SPACE-DIVISION MULTIPLEXED TRANSMISSION WITH MULTIPLE TRANSMISSION RECEPTION POINTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18034033 titled 'UNICAST MEASUREMENT AND DETERMINATION FOR SPACE-DIVISION MULTIPLEXED TRANSMISSION WITH MULTIPLE TRANSMISSION RECEPTION POINTS

Simplified Explanation

This patent application describes a method for improving the performance of unicast links between multiple user equipments (UEs) in a wireless communication system. The method involves the use of multiple transmit and receive points (TRPs) in the UEs to measure the channel quality and interference levels on the unicast links.

  • The first UE sends a reference signal (RS) from one of its TRPs to the second UE on a first unicast link.
  • Based on the RS received, the first UE measures the channel quality of the first unicast link from the second UE and the interference level from a third UE on a second unicast link.
  • The first UE then sends another RS from a different TRP to the third UE on the second unicast link.
  • Based on the second RS received, the first UE measures the channel quality of the second unicast link from the third UE and the interference level from the second UE on the first unicast link.
  • The first UE applies spatial division multiplexing (SDM) techniques to optimize the performance of both unicast links based on the measured channel quality and interference levels.

Overall, this patent application proposes a method for dynamically adjusting the transmission parameters of unicast links between UEs based on real-time measurements of channel quality and interference levels, leading to improved performance and reliability of the wireless communication system.


Original Abstract Submitted

A first UE transmits, on a first unicast link to a second UE, a first RS from a first TRP of the first UE. The first UE receives, based on the first RS transmitted, a first channel measurement for the first unicast link from the second UE and a first interference measurement for a second unicast link from a third UE. The first UE transmits, on the second unicast link with the third UE, a second RS from a second TRP of the first UE. The first UE receives, based on the second RS transmitted, a second channel measurement for the second unicast link from the third UE and a second interference measurement for the first unicast link from the second UE. The first UE applies SDM for the first unicast link and the second unicast link based on the received channel and interference measurements.
