SIDELINK CARRIER AGGREGATION WITH CROSS-CARRIER RETRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240223315 titled 'SIDELINK CARRIER AGGREGATION WITH CROSS-CARRIER RETRANSMISSION

The abstract describes a patent application for a transmitting sidelink device that assigns a transport block to a logical hybrid automatic repeat request (HARQ) entity, maps the block to a carrier, transmits it to a receiving sidelink device, associates the block with a first sidelink control information (SCI) for reference, maps the block to a different carrier, and retransmits it with a second SCI for identification of the HARQ entity. The receiving device maps the block to the identified HARQ entity, detects the retransmission, and maps it accordingly.

• Assigns transport blocks to HARQ entities
• Maps blocks to carriers for transmission
• Associates blocks with SCIs for identification
• Retransmits blocks on different carriers with new SCIs
• Receiving device maps blocks to identified HARQ entities

Potential Applications: - Sidelink communication systems - Wireless networks - Internet of Things (IoT) devices

Problems Solved: - Efficient transmission of data in sidelink communication - Improved reliability through HARQ mechanisms

Benefits: - Enhanced data transmission efficiency - Increased reliability in wireless communication - Optimal resource utilization

Commercial Applications: Title: "Enhancing Sidelink Communication Efficiency with HARQ Mechanisms" This technology can be utilized in various industries such as telecommunications, IoT, and smart devices to improve data transmission reliability and efficiency.

Questions about the technology: 1. How does the use of HARQ mechanisms improve data transmission in sidelink communication? 2. What are the potential challenges in implementing this technology in real-world applications?

Original Abstract Submitted

a transmitting sidelink device assigns a transport block (tb) to a logical hybrid automatic repeat request (harq) entity, maps the tb to an carrier, transmits the tb to a receiving sidelink device, the tb is associated with a first sidelink control information (sci) that cross-references the tb to an identifier of the logical harq entity, maps the tb to a different carrier, and retransmits the tb on the different carrier, the retransmitted tb is associated with a second sci that cross-references the tb to the identifier of the logical harq entity. a receiving sidelink device receives the tb and sci, maps the tb to the identified logical harq entity, detects the retransmission, and maps the retransmission to the identified logical harq entity. a transmitting sidelink device generates packets in advance and transmits one of the generated packets when required.
