ACKNOWLEDGEMENT FEEDBACK IN UNLICENSED NEW RADIO - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240260045 titled 'ACKNOWLEDGEMENT FEEDBACK IN UNLICENSED NEW RADIO
The abstract describes methods, systems, and devices for wireless communications, specifically in unlicensed spectrum bands.
- User equipment (UE) and base stations communicate in shared radio frequency spectrum bands.
- The UE determines the codebook size for transmitting Hybrid Access Request (HARQ) Acknowledgement (ACK) feedback in the unlicensed spectrum.
- The UE bases the HARQ ACK codebook size on the number of HARQ processes it has been configured with.
- Additionally, the UE may base the codebook size on the number and duration of downlink channel monitoring occasions indicated by the base station.
- The UE may use a combination of these techniques to determine the HARQ ACK codebook size.
Potential Applications: - Wireless communication systems - Unlicensed spectrum communication - Hybrid Access Request (HARQ) protocols
Problems Solved: - Efficient transmission of HARQ ACK feedback in unlicensed spectrum - Optimal codebook size determination for wireless communications
Benefits: - Improved reliability and efficiency in wireless communication - Enhanced performance in unlicensed spectrum bands
Commercial Applications: Title: "Enhanced Wireless Communication Systems for Unlicensed Spectrum Bands" This technology can be applied in industries such as telecommunications, IoT, and smart devices, where reliable and efficient wireless communication is essential. It can also benefit companies looking to optimize their communication systems in unlicensed spectrum bands.
Questions about Wireless Communications in Unlicensed Spectrum Bands: 1. How does the codebook size impact the transmission of HARQ ACK feedback in unlicensed spectrum bands? 2. What are the key factors that influence the determination of the HARQ ACK codebook size in wireless communications?
Original Abstract Submitted
methods, systems, and devices for wireless communications are described. a user equipment (ue) and a base station may communicate in an unlicensed spectrum (e.g., a shared radio frequency spectrum band). as such, the ue may determine a codebook size for transmitting hybrid access request (harq) acknowledgement (ack) feedback with respect to the unlicensed spectrum. accordingly, the ue may base the harq ack codebook size on a number of harq processes with which the ue has been configured. additionally or alternatively, the ue may base the harq ack codebook size on a number and/or duration of downlink channel monitoring occasions indicated by the base station. in some cases, the ue may base the harq ack codebook size on a combination of the techniques described herein.
