CHANNEL OCCUPANCY TIME CONTENTION GRANT FOR SIDELINK COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17449945 titled 'CHANNEL OCCUPANCY TIME CONTENTION GRANT FOR SIDELINK COMMUNICATIONS

Simplified Explanation

The abstract describes a wireless communication system and method for transmitting control information. The method involves a sidelink user equipment (UE) receiving a configuration from a base station (BS) indicating a listen-before-talk (LBT) window. The configuration specifies the start and end of the LBT window. During this window, the UE performs a listen-before-talk process to check for channel occupancy in a shared radio frequency band. If the LBT is successful, the UE transmits one or more transport blocks (TBs) to another sidelink UE during the channel occupancy time (COT).

  • The method involves a sidelink UE receiving a configuration from a BS indicating a listen-before-talk (LBT) window.
  • The configuration specifies the start and end of the LBT window.
  • During the LBT window, the UE performs a listen-before-talk process to check for channel occupancy in a shared radio frequency band.
  • If the LBT is successful, the UE transmits one or more transport blocks (TBs) to another sidelink UE during the channel occupancy time (COT).

Potential Applications

  • This technology can be applied in wireless communication systems where control information needs to be transmitted between UEs.
  • It can be used in scenarios where multiple UEs need to share a radio frequency band efficiently.
  • The method can be implemented in various wireless communication standards and protocols.

Problems Solved

  • The method solves the problem of efficiently transmitting control information in wireless communication systems.
  • It addresses the challenge of avoiding interference between multiple UEs sharing the same radio frequency band.
  • The listen-before-talk process helps in identifying channel occupancy and prevents collisions during transmission.

Benefits

  • The method allows for reliable transmission of control information between UEs.
  • It improves the efficiency of sharing a radio frequency band by using a listen-before-talk approach.
  • By avoiding collisions, the method reduces the chances of data loss and improves overall system performance.


Original Abstract Submitted

Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a sidelink user equipment (UE) may include receiving, from a base station (BS), a configuration indicating a listen-before-talk (LBT) window, wherein the configuration indicates a start and an end associated with the LBT window, performing, during the LBT window, an LBT for a channel occupancy time (COT) in a shared radio frequency band, and transmitting, to another sidelink UE, based on the LBT being successful, one or more transport blocks (TBs) during the COT.
