Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of priority under 35 U.S.C. § 120 as a continuation of PCT Patent Application No. PCT/CN2020/079732, filed on Mar. 17, 2020, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD The disclosure relates generally to wireless communications and, more particularly, to systems and methods for sidelink configuration. BACKGROUND Sidelink (SL) communication is a wireless radio communication directly between two or more user equipment devices (hereinafter “UE”). In this type of communication, two or more UEs that are geographically proximate to each other can directly communicate without going through an eNode or a base station (hereinafter “BS”), or a core network. Data transmission in sidelink communications is thus different from typical cellular network communications, which transmit data to a BS (i.e., uplink transmissions) or receive date from a BS (i.e., downlink transmissions). In sidelink communications, data is transmitted directly from a source UE to a target UE through the Unified Air Interface, e.g., PC5 interface, without passing through a BS SL communication can help save radio spectrum resources, reduce data transmission pressure on the network, reduce system resource consumption, increase spectral efficiency, reduce transmission power consumption and/or improve network operation costs.
