AI Technical Summary

Problems solved by technology

For example, scheduling in mode 3 can lead to scheduling related constraints such as latency and SL delivery being dependent on DCI
Furthermore, the design of LTE Mode 4 relies on sensing and reservation to avoid collisions or resource conflicts between autonomous UE transmissions, and thus does not utilize radio resources efficiently
Also, LTE Mode 4 is primarily designed to handle periodic traffic and may be suboptimal for aperiodic traffic

Embodiment Construction

[0035] The invention has been made with reference to the accompanying drawings, in which embodiments are shown. However, many different embodiments may be utilized, so the description should not be construed as limited to the embodiments set forth herein. Rather, these examples are provided so that this disclosure will be thorough and complete. Throughout the specification, like numbers refer to like elements. The separate blocks or illustrated separation of functional elements or modules of the illustrated systems and devices do not necessarily require a physical separation of these functions or modules, as communication between these elements can be through message passing, Function calls, shared memory space, etc. occur. Therefore, although functions or modules are shown separately herein for ease of explanation, these functions or modules need not be implemented in physically or logically separate platforms. Different devices may have different designs such that while s...

Abstract

In one embodiment, a method includes sensing, by a first user equipment (UE), a signal transmitted by a second UE, the signal indicating a resource reservation of a shared channel for sidelink (SL) transmissions by the second UE and a priority associated with the SL transmissions; the first UE determines a threshold according to the type of SL transmission and the priority; and the first UE selects resources in the shared channel according to the threshold value for SL transmission performed by the first UE.

Description

[0001] Related Application Cross Reference [0002] This application requires the invention titled "Sensing and Resource Selection Based on Priority of Sidelink Transmissions (SENSING AND RESOURCE SELECTION BASED ON PRIORITIES FOR SIDELINKTRANSMISSIONS)" filed on August 10, 2020, with application number 16 / 989,273 US NON-PROVISIONAL APPLICATION CLAIMING AN INVENTION TITLE SENSING AND RESOURCE SELECTION BASED ON PRIORITIES FOR SIDELINK TRANSMISSIONS, FILED AUGUST 16, 2019, The benefit of US Provisional Application Serial No. 62 / 888,430, which is hereby incorporated by reference as if reproduced in its entirety. technical field [0003] The present application relates to methods and apparatuses for sidelink (SL) transmission and resource allocation.
