METHOD AND APPARATUS FOR FEEDING BACK HARQ-ACK IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17798223 titled 'METHOD AND APPARATUS FOR FEEDING BACK HARQ-ACK IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The patent application describes a terminal device for wireless communication that can transmit and receive data. Here are the key points:
- The terminal receives configuration information from a base station for code block group (CBG)-based uplink transmission.
- It also receives a second set of configuration information that includes a method for configuring a downlink feedback information (DFI) bitmap.
- The terminal uses the first configuration information to transmit an uplink signal to the base station using CBG-based transmission.
- It then receives DFI from the base station, which contains feedback information about the CBG-based uplink signal.
- Based on the second configuration information, the terminal determines a contention window value, which is a parameter that controls the random access procedure in wireless communication.
Potential applications of this technology:
- This technology can be used in various wireless communication systems, such as cellular networks, Wi-Fi networks, and IoT networks.
- It can improve the efficiency and reliability of uplink transmission by using CBG-based transmission and receiving feedback information from the base station.
Problems solved by this technology:
- Traditional uplink transmission methods may not be efficient in handling large amounts of data or in scenarios with high interference.
- The use of CBG-based transmission and the feedback information provided by the base station can help optimize the uplink transmission process and improve overall system performance.
Benefits of this technology:
- The use of CBG-based transmission allows for more efficient and reliable uplink transmission, especially in scenarios with high interference or large amounts of data.
- The feedback information provided by the base station helps the terminal device adjust its contention window value, leading to improved system performance and reduced contention among multiple devices.
- Overall, this technology can enhance the performance and reliability of wireless communication systems.
Original Abstract Submitted
Provided is a terminal for performing transmission and reception of data in a wireless communication system, wherein the terminal receives, from a base station, first configuration information for code block group (CBG)-based uplink transmission, and second configuration information including a downlink feedback information (DFI) bitmap configuration method, transmits a CBG-based uplink signal to the base station, based on the first configuration information, receives, from the base station, DFI including feedback information about the CBG-based uplink signal, based on the second configuration information, and determines a contention window value of the terminal, based on the feedback information included in the received DFI, wherein the DFI bitmap configuration method indicates whether the feedback information is for feedback in units of transport blocks (TBs) or for feedback for one or more CBGs.
