DETERMINING PHASE TRACKING REFERENCE SIGNALS IN MULTIPLE TRANSMISSION POINTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18222865 titled 'DETERMINING PHASE TRACKING REFERENCE SIGNALS IN MULTIPLE TRANSMISSION POINTS

Simplified Explanation

The abstract describes a method for a user equipment (UE) in a multiple transmission points communication system. The method involves receiving downlink control information (DCI) that indicates a scheme for scheduled data transmission on physical resource blocks (PRBs). The PRBs are divided into subsets associated with different transmission points.

  • The method determines the frequency density of reference signals (PT-RS) for each subset of PRBs based on the number of PRBs in each subset.
  • This allows for efficient transmission and reception of data by the UE.
  • The method can be implemented by a UE, a base station, or a base station method.
  • The innovation improves the performance and reliability of communication in a multiple transmission points system.


Original Abstract Submitted

A method for a UE in a multiple transmission points communication system, mTRP, scheme, is provided. The method includes receiving downlink control information, DCI, indicating at least two transmission points scheme for a scheduled data transmission on physical resource blocks, PRBs. The PRBs includes at least a first subsets of PRBs, associated with a first transmission point, and a second subset of PRBs, associated with a second transmission point. The method further includes determining a first PT-RS frequency density for the first set of PRBs based on the number of PRBs in the first set of PRBs and a second PT-RS frequency density based on the number of PRBs in the second set of PRBs. A UE, methods for a base station and a base station are also provided.
