MULTI-BEAM OPERATIONS FOR MULTIPLE COMPONENT CARRIERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18066244 titled 'MULTI-BEAM OPERATIONS FOR MULTIPLE COMPONENT CARRIERS

Simplified Explanation

The patent application describes a method for operating a User Equipment (UE) in a wireless communication system. Here are the key points:

  • The UE receives configuration information which includes a list of Component Carriers (CCs) and a set of Transmission Configuration Indicator (TCI) states.
  • The UE also receives a TCI state update via a medium, which is common for a subset of CCs.
  • The subset of CCs can include up to n CCs, where n is less than or equal to the total number of CCs in the list.
  • For each CC in the subset, the UE determines a beam based on the TCI state update.
  • The determined beam is then applied for the reception of a downlink control channel or a downlink data channel associated with the respective CC.

Potential applications of this technology:

  • This method can be used in wireless communication systems to improve the reception of downlink control and data channels.
  • It can enhance the performance of User Equipment by optimizing the beamforming process based on the TCI state update.
  • The technology can be implemented in various wireless communication devices such as smartphones, tablets, and IoT devices.

Problems solved by this technology:

  • The method addresses the challenge of efficiently utilizing multiple CCs in a wireless communication system.
  • It solves the problem of determining the appropriate beam for each CC based on the TCI state update.
  • By optimizing the beamforming process, it helps improve the overall performance and reliability of the communication system.

Benefits of this technology:

  • The method allows for efficient utilization of available CCs, leading to improved data transmission rates and network capacity.
  • By optimizing the beamforming process, it enhances the signal quality and reduces interference, resulting in better communication reliability.
  • The technology can improve the user experience by providing faster and more stable wireless connections.


Original Abstract Submitted

A method for operating a UE comprises receiving configuration information including a list of CCs and a set of TCI states; receiving, based on the configuration information, a TCI state update via a medium, wherein: the TCI state update is common for a first subset of CCs, the first subset of CCs includes n ≤ N CCs, and N = a number of CCs in the list of CCs; and for each CC(i) in the first subset of CCs, determining a beam based on the TCI state update, and applying the beam for a reception of a downlink control channel or a downlink data channel associated with the CC(i), wherein i is an index and takes a value from {1, 2, ..., n}, wherein the beam is determined based on a spatial quasi-co-location property used to receive or transmit a source RS indicated via the TCI state update.
