SIDELINK FEEDBACK ENHANCEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240306021 titled 'SIDELINK FEEDBACK ENHANCEMENT

The abstract of the patent application describes a user equipment (UE) in a wireless communication network that can form a sidelink group with other UEs in the network. The UE is capable of receiving a sidelink groupcast message from a select UE in the group, which includes sidelink channel state information (CSI) request and transmission of a CSI reference signal. The UE processes the groupcast message and provides an SL CSI report to the select UE based on measured SL CSI.

• User equipment (UE) can form a sidelink group with other UEs in a wireless communication network.
• Capable of receiving a sidelink groupcast message from a select UE in the group.
• The groupcast message includes sidelink channel state information (CSI) request and transmission of a CSI reference signal.
• Process the groupcast message and provide an SL CSI report to the select UE based on measured SL CSI.

Potential Applications: - Enhancing communication reliability in wireless networks. - Improving coordination and data exchange between UEs. - Facilitating efficient resource allocation in network communication.

Problems Solved: - Addressing the need for effective group communication among UEs. - Enhancing the management of CSI in sidelink transmissions.

Benefits: - Increased network efficiency and reliability. - Enhanced communication capabilities for UEs. - Improved coordination and data exchange in wireless networks.

Commercial Applications: Title: "Enhanced Sidelink Communication for Wireless Networks" This technology could be utilized in: - 5G and future wireless communication networks. - Internet of Things (IoT) devices requiring reliable group communication. - Public safety and emergency communication systems.

Questions about Sidelink Communication: 1. How does the UE determine which UE in the sidelink group to send the SL CSI report to? 2. What are the potential challenges in implementing sidelink group communication in real-world network environments?

Frequently Updated Research: Stay updated on advancements in sidelink communication protocols and standards to ensure compatibility with evolving wireless network technologies.

Original Abstract Submitted

a user equipment (ue) associated with a wireless communication network is disclosed. the ue comprises one or more processors configured to form a sidelink group with one or more other ues associated with the wireless communication network. in some aspects, the one or more processors are further configured to receive a sidelink (sl) groupcast message from a select ue of the one or more other ues of the sidelink group, the sl groupcast message comprising a sl channel state information (csi) request and a transmission of a sl channel state information reference signal (csi-rs). in some aspects, the one or more processors are further configured to process the sl groupcast message; and selectively provide an sl csi report derived based on a measured sl csi, to the select ue, in response to processing the sl groupcast message.
