METHOD AND APPARATUS FOR UPLINK TRANSMISSIONS IN FRAME-BASED EQUIPMENT NR UNLICENSED - A simplified explanation of the abstract

This abstract first appeared for US patent application 18447960 titled 'METHOD AND APPARATUS FOR UPLINK TRANSMISSIONS IN FRAME-BASED EQUIPMENT NR UNLICENSED

Simplified Explanation

This patent application describes methods and apparatuses for operating base stations (BSs) and user equipment (UE) in a wireless communication system. The focus is on utilizing a shared spectrum channel efficiently.

  • The UE receives a first DCI (Downlink Control Information) from a BS over the shared spectrum channel.
  • The first DCI includes a COT (Channel Occupancy Time) of the BS, which is divided into a first portion for downlink transmission and a second portion for uplink transmission.
  • There is a gap between the first and second portions of the COT.
  • The UE determines the duration of the gap and performs a channel access procedure based on it.
  • During the gap, the UE senses the shared spectrum channel to check if it is idle.
  • If the channel is sensed as idle, the UE transmits the uplink transmission in the second portion of the COT.
  • The UE receives the downlink transmission in the first portion of the COT.

Overall, this patent application proposes a method for efficient channel access and transmission scheduling in a wireless communication system, ensuring optimal utilization of the shared spectrum channel.


Original Abstract Submitted

Methods and apparatuses of a BSs and UEs in a wireless communication system are provided. A method of operating the UE comprises: receiving, from a BS over a shared spectrum channel, a first DCI including a COT of the BS; determining a first portion of the COT for a downlink transmission from the BS and a second portion of the COT for an uplink transmission to the BS, wherein the COT includes a gap between the first and second portions of the COT; performing a channel access procedure based on a duration of the gap; receiving the downlink transmission in the first portion of the COT; and transmitting the uplink transmission in the second portion of the COT based on a sensing status of the shared spectrum channel that is sensed as an idle state during the channel access procedure in the duration of the gap.
