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

This abstract first appeared for US patent application 18282773 titled 'SIDELINK CARRIER AGGREGATION WITH CROSS-CARRIER HARQ FEEDBACK

Simplified Explanation

The abstract describes a patent application for facilitating sidelink carrier aggregation with cross-carrier feedback in wireless communication.

• Wireless communication method involving cross-carrier feedback:

   - Receiving a sidelink message with a transport block on a carrier
   - Generating Hybrid Automatic Repeat Request (HARQ) feedback for the transport block
   - Determining a feedback carrier for transmitting cross-carrier feedback
   - Mapping the HARQ feedback to the feedback carrier
   - Transmitting the HARQ feedback on the feedback carrier

Potential Applications

Problems Solved

- Efficient utilization of multiple carriers for sidelink communication - Improved reliability and performance of wireless communication - Minimizing interference and optimizing feedback transmission

Benefits

- Enhanced data transmission rates - Increased network capacity - Better quality of service for users

Potential Commercial Applications

Optimized for: - Telecommunication companies - IoT device manufacturers - Automotive industry for connected vehicles

Possible Prior Art

There may be prior art related to: - Cross-carrier feedback in wireless communication systems - Sidelink carrier aggregation techniques

How does this technology impact battery life in wireless devices?

This article does not address the potential impact of this technology on the battery life of wireless devices. Implementing cross-carrier feedback and carrier aggregation may require additional processing power, which could affect battery consumption.

What are the potential security implications of cross-carrier feedback transmission?

The article does not discuss the security aspects of transmitting feedback on a different carrier. It is essential to consider potential vulnerabilities and security measures to protect the feedback transmission from unauthorized access or interference.

Original Abstract Submitted

Apparatus, methods, and computer-readable media for facilitating sidelink carrier aggregation with cross-carrier feedback are disclosed herein. An example method for wireless communication at a first wireless device includes receiving, from a second wireless device, a first sidelink message including a first transport block (TB) on a first carrier. The example method also includes generating a first Hybrid Automatic Repeat Request (HARQ) feedback for the first TB. The example method also includes determining a first feedback carrier to transmit cross-carrier feedback. The example method also includes mapping the first HARQ feedback for the first TB to the first feedback carrier, the first feedback carrier being different than the first carrier. The example method also includes transmitting the first HARQ feedback on the first feedback carrier to the second wireless device.
