==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.

== Potential Applications ==
This technology can be applied in V2V communication systems, autonomous vehicles, smart transportation systems, and connected car applications.

== Problems Solved ==
This technology solves the problem of efficiently allocating TTIs for V2V sidelink transmissions, distinguishing between legacy and non-legacy UEs, and ensuring effective communication in vehicular networks.

== Benefits ==
The benefits of this technology include improved communication reliability, reduced interference, optimized resource allocation, and enhanced V2V communication performance.

== Potential Commercial Applications ==
Potential commercial applications of this technology include automotive industry, smart city infrastructure, transportation companies, and communication equipment manufacturers.

== Possible Prior Art ==
One possible prior art could be the use of different TTIs for sidelink transmissions in cellular networks or other wireless communication systems.

=== Unanswered Questions ===

=== How does this technology impact overall network efficiency in V2V communication systems? ===
This technology improves network efficiency by optimizing TTI allocation and ensuring reliable communication between legacy and non-legacy UEs in V2V systems.

=== What are the implications of using short TTIs for V2V sidelink transmissions on system latency? ===
Using short TTIs for V2V sidelink transmissions can reduce system latency by enabling quicker data exchange between vehicles, enhancing real-time communication in vehicular networks.


==Original Abstract Submitted==

embodiments of a user equipment (ue) and methods for communication are generally described herein. the ue may select, from a plurality of short transmission time intervals (ttis), a short tti for a vehicle-to-vehicle (v2v) sidelink transmission by the ue. the short ttis may occur within a legacy ttl. the short ttis may be allocated for v2v sidelink transmissions by nonlegacy ues. the legacy tti may be allocated for v2v sidelink transmissions by legacy ues. the ue may transmit, in accordance with the legacy tti, a legacy physical sidelink control channel (pscch) to indicate, to legacy ues, the v2v sidelink transmission by the ue. the ue may transmit, in accordance with the selected short tti, a short pscch (spscch) to indicate, to non-legacy ues, the v2v sidelink transmission by the ue.
