User Equipment (UE) and Methods for Vehicle-to-Vehicle (V2V) Sidelink Communication in Accordance with a Short Transmission Time Interval (TTI) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240137928 titled 'User Equipment (UE) and Methods for Vehicle-to-Vehicle (V2V) Sidelink Communication in Accordance with a Short Transmission Time Interval (TTI)

Simplified Explanation

The abstract describes embodiments of a user equipment (UE) and methods for communication, specifically focusing on vehicle-to-vehicle (V2V) sidelink transmissions. The UE can select a short transmission time interval (TTI) for V2V sidelink transmission, which may occur within a legacy TTI. Non-legacy UEs can use short TTIs for V2V sidelink transmissions, while legacy UEs use the legacy TTI. The UE transmits a legacy physical sidelink control channel (PSCCH) on the legacy TTI to indicate V2V sidelink transmission to legacy UEs, and a short PSCCH (SPSCCH) on the selected short TTI to indicate the transmission to non-legacy UEs.

• Short transmission time intervals (TTIs) can be selected for vehicle-to-vehicle (V2V) sidelink transmissions.
• Legacy UEs use legacy TTIs, while non-legacy UEs use short TTIs for V2V sidelink transmissions.
• The UE transmits a legacy physical sidelink control channel (PSCCH) on the legacy TTI and a short PSCCH (SPSCCH) on the selected short TTI to indicate the transmission to different types of UEs.
