NETWORK-COORDINATED MODE 2 SIDELINK IN UNLICENSED SPECTRUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17819164 titled 'NETWORK-COORDINATED MODE 2 SIDELINK IN UNLICENSED SPECTRUM

Simplified Explanation

The patent application relates to wireless communication in unlicensed spectrum for sidelink communications.

• User equipment (UE) can request parameters for sidelink communications via a buffer status report or scheduling request to a network node.
• The network node allocates sidelink resources, such as resource block sets, in the unlicensed spectrum to the UE.
• The UE can then use the allocated resources to communicate with another sidelink UE after performing listen-before-talk (LBT) to avoid interference.

Potential Applications

• Internet of Things (IoT) devices communicating in unlicensed spectrum.
• Vehicle-to-vehicle communication for improved road safety.
• Peer-to-peer file sharing in crowded Wi-Fi environments.

Problems Solved

• Efficient allocation of resources for sidelink communications.
• Mitigation of interference in unlicensed spectrum.
• Improved reliability and performance of wireless communication.

Benefits

• Increased capacity for wireless communication.
• Enhanced reliability of sidelink communications.
• Better utilization of unlicensed spectrum resources.

Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node and via a buffer status report (BSR) or scheduling request (SR), a request indicating one or more parameters associated with sidelink communications in an unlicensed spectrum. The UE may receive, from the network node, a sidelink resource allocation indicating one or more resource block (RB) sets associated with the unlicensed spectrum. The UE may transmit, to a sidelink UE and based at least in part on the sidelink resource allocation and on a result of performing listen-before-talk (LBT), a sidelink communication. Numerous other aspects are described.
