MINI-SLOT CHANNEL ACCESS FOR A SIDELINK USER EQUIPMENT (UE) - A simplified explanation of the abstract
This abstract first appeared for US patent application 18448096 titled 'MINI-SLOT CHANNEL ACCESS FOR A SIDELINK USER EQUIPMENT (UE)
Simplified Explanation
The abstract describes a method for wireless communication at a first sidelink user equipment (UE) involving listen-before-talk (LBT) for channel occupancy time (COT), selecting full-slot or half-slot sidelink channel waveform hypothesis, and transmitting sidelink information to a second sidelink UE.
- Method for wireless communication at a first sidelink UE
- Includes LBT for COT in a shared radio frequency band
- Selects full-slot or half-slot sidelink channel waveform hypothesis based on timing associated with clearing the LBT
- Transmits sidelink information to a second sidelink UE during the COT
- TBS associated with the COT has a fixed number of resources
- Same number of resources for full-slot and half-slot sidelink channel waveform hypothesis

Original Abstract Submitted
A method for wireless communication at a first sidelink user equipment (UE) includes performing, in a shared radio frequency band, a listen-before-talk (LBT) for a channel occupancy time (COT). The method also includes selecting a full-slot sidelink channel waveform hypothesis associated with a first starting symbol, or a half-slot sidelink channel waveform hypothesis associated with a second starting symbol, in accordance with a timing associated with clearing the LBT. The method further includes transmitting, during the COT, sidelink information to a second sidelink UE, a transport block size (TBS) associated with the COT having a fixed number of resources, the fixed number of resources being a same number of resources for full-slot sidelink channel waveform hypothesis and the half-slot sidelink channel waveform hypothesis.
