METHOD AND APPARATUS FOR CHANNEL OCCUPANCY TIME SHARING IN WIRELESS COMMUNICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17441362 titled 'METHOD AND APPARATUS FOR CHANNEL OCCUPANCY TIME SHARING IN WIRELESS COMMUNICATION

Simplified Explanation

Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs.

• The UE determines that a portion of the maximum COT (MCOT) provided to it will be unused.
• The UE generates COT sharing information that identifies the starting point and duration of the unused portion of the MCOT.
• The COT sharing information is encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission.
• If the unused portion begins part-way through a slot, the starting symbol of the unused portion or the ending symbol of the used portion may also be encoded into the uplink transmission.
• This allows the gNB to repurpose the unused COT instead of wasting it.

Potential Applications

• This technology can be applied in wireless communication systems, particularly in 5G networks.
• It can improve the efficiency of channel usage and enhance overall network performance.

Problems Solved

• Unused channel occupancy time (COT) is a valuable resource that is often wasted in wireless communication systems.
• This technology solves the problem of wasted COT by allowing the gNB to repurpose the unused time for other users.

Benefits

• Improved channel efficiency: By repurposing unused COT, the gNB can allocate it to other users, maximizing the utilization of the channel.
• Enhanced network performance: The efficient utilization of COT leads to better overall network performance, including increased throughput and reduced latency.

Original Abstract Submitted

Methods and apparatuses are disclosed for signaling unused channel occupancy time (COT) to the gNB for COT sharing among other UEs. Upon determining that a portion of the maximum COT (MCOT) provided to the UE will be unused, the UE can generate COT sharing information for transmission back to the gNB. The COT sharing information identifies a starting point and a duration (e.g., a number of consecutive slots) of the unused portion of the MCOT. This information is then encoded into configured grant uplink control information (UG-UCI) and transmitted to the gNB as part of the uplink transmission. In aspects, the unused portion may begin part-way through a slot. In this instance, a starting symbol of the unused portion or an ending symbol of the used portion may also be encoded into the uplink transmission. In this manner, unused COT is not wasted, but rather repurposed by the gNB.
