Beam Management in Multi-TRP Operation - A simplified explanation of the abstract

This abstract first appeared for US patent application 18465344 titled 'Beam Management in Multi-TRP Operation

Simplified Explanation

The abstract describes a patent application related to beam management operations for a user equipment (UE) in a cell. The cell performs various operations to manage the transmission and reception of signals between the cell and the UE.

• The cell transmits multiple reference signals to the UE through two different transmission reception points (TRPs).
• The UE selects one beam from each group of reference signals transmitted by the cell.
• The cell receives an indication from the UE about the selected beams.
• The cell then uses the selected beams to transmit downlink data to the UE.

Potential Applications

• This technology can be applied in cellular networks to improve the efficiency and reliability of communication between cells and user equipment.
• It can enhance the performance of wireless communication systems in areas with high user density or challenging propagation conditions.

Problems Solved

• Efficient beam management is crucial for optimizing the performance of cellular networks.
• This technology solves the problem of selecting the most suitable beams for transmission and reception in a cell, based on the UE's selection of reference signals.

Benefits

• The use of multiple reference signals and beams allows for improved signal quality and coverage.
• By transmitting downlink data through selected beams, the technology enhances the overall data transmission efficiency.
• The system can adapt to changing conditions and optimize the beam selection process, leading to better network performance.

Original Abstract Submitted

A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.
