METHODS FOR BEAM DETERMINATION AFTER BEAM PAIR LINK INDICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17882480 titled 'METHODS FOR BEAM DETERMINATION AFTER BEAM PAIR LINK INDICATION

Simplified Explanation

Methods, systems, and devices for wireless communications are described in this patent application. The innovation focuses on signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). Here are the key points:

  • The patent application introduces the concept of BPLs for directional transmission beams between a base station and a user equipment (UE).
  • A threshold value is determined, representing the time required for a UE to receive and decode control information.
  • The UE maintains a BPL for data transmission until an indication is received to change the BPL.
  • The decision to change between BPLs is based on the threshold value and a scheduling offset between a control channel transmission and the start of the data transmission interval.

Potential Applications

This technology has potential applications in various wireless communication systems, including:

  • 5G and beyond networks
  • Mobile communication systems
  • Internet of Things (IoT) devices
  • Wireless broadband networks

Problems Solved

The patent application addresses the following problems in wireless communications:

  • Efficient signaling and switching of beam pair links (BPLs) for directional transmission beams.
  • Optimizing the use of BPLs to improve data transmission efficiency.
  • Ensuring timely reception and decoding of control information by user equipment (UE).

Benefits

The technology described in this patent application offers several benefits, including:

  • Enhanced data transmission efficiency through the use of BPLs.
  • Improved control information reception and decoding by user equipment (UE).
  • Increased flexibility in switching between BPLs based on scheduling and threshold values.
  • Potential for improved performance and reliability in wireless communication systems.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.
