TYPE-1 HARQ-ACK CODEBOOK FOR SPS HARQ-ACK DEFERRAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195536 titled 'TYPE-1 HARQ-ACK CODEBOOK FOR SPS HARQ-ACK DEFERRAL

The abstract describes a method, system, and apparatus related to a wireless device that generates and modifies a codebook for uplink and downlink time slots.

  • The wireless device includes processing circuitry to create a first HARQ-ACK codebook for a specific uplink time slot.
  • The first codebook contains a plurality of HARQ-ACK bits and is adjusted based on timing parameters associated with a second plurality of HARQ-ACK bits.
  • Each of the second plurality of bits corresponds to a downlink time slot within a group of downlink time slots.
  • The first codebook is modified by considering deferred HARQ-ACK bits from the second plurality.
  • The modified codebook is then transmitted during the designated uplink time slot.

Potential Applications: - This technology can be applied in wireless communication systems to enhance feedback mechanisms for data transmission. - It can improve the efficiency and reliability of communication between devices in a network.

Problems Solved: - Addressing the need for efficient feedback mechanisms in wireless communication systems. - Enhancing the performance of HARQ-ACK codebooks for better data transmission.

Benefits: - Improved reliability and accuracy of feedback in wireless communication. - Enhanced data transmission efficiency and overall network performance.

Commercial Applications: Title: Enhanced Wireless Communication Feedback System This technology can be utilized in 5G networks, IoT devices, and other wireless communication systems to optimize data transmission and network reliability. It can be valuable for telecommunications companies, IoT manufacturers, and network infrastructure providers.

Questions about the technology: 1. How does this technology improve the reliability of wireless communication systems? 2. What are the potential implications of using modified HARQ-ACK codebooks in network optimization?


Original Abstract Submitted

a method, system and apparatus are disclosed. according to some embodiments, a wireless device is provided. the wireless device includes processing circuitry configured to generate a first harq-ack codebook for a first uplink time slot, where the first harq-5 ack codebook includes a first plurality of harq-ack bits, to determine a second plurality of harq-ack bits, where each of the second plurality of harq-ack bits is associated with a respective timing parameter, and each of the second plurality of harq-ack bits is mapped to a respective downlink time slot of a plurality of downlink time slots based on the respective timing parameter, to modify the first harq-ack codebook based on at least one 0 deferred harq-ack bit of the second plurality of harq-ack bits, and to cause transmission of the modified first harq-ack codebook during the first uplink time slot.
