METHOD AND APPARATUS FOR SENDING HARQ-ACK, METHOD AND APPARATUS FOR RECEIVING HARQ-ACK, DEVICE, AND STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18548277 titled 'METHOD AND APPARATUS FOR SENDING HARQ-ACK, METHOD AND APPARATUS FOR RECEIVING HARQ-ACK, DEVICE, AND STORAGE MEDIUM

Simplified Explanation

The method described in the abstract involves a user equipment determining slot sets, slot groups, and target slots to send a HARQ-ACK codebook for multi-TTI PDSCHs. The user equipment then determines a logical HARQ-ACK based on the HARQ-ACKs received in each slot group and sends the HARQ-ACK codebook.

• Determining slot sets and slot groups:

 - The user equipment identifies a first slot set containing slots for multi-TTI PDSCHs and a second slot set for the HARQ-ACK codebook.
 - Slot groups are determined based on slots present in the first set but not in the second set.

• Determining logical HARQ-ACK and sending the codebook:

 - A logical HARQ-ACK is calculated based on the received HARQ-ACKs in each slot group and the target slot corresponding to each group.
 - The user equipment then sends the HARQ-ACK codebook containing the logical HARQ-ACK information.

Potential Applications

This technology can be applied in wireless communication systems to improve the efficiency of HARQ-ACK feedback for multi-TTI PDSCHs.

Problems Solved

1. Efficient HARQ-ACK feedback for multi-TTI PDSCHs. 2. Simplified method for determining logical HARQ-ACK information.

Benefits

1. Enhanced reliability in HARQ-ACK feedback. 2. Improved performance in wireless communication systems.

Potential Commercial Applications

Optimizing HARQ-ACK feedback in 5G networks for better throughput and reliability.

Possible Prior Art

Prior art may include methods for HARQ-ACK feedback in wireless communication systems, but this specific approach of determining slot sets, slot groups, and logical HARQ-ACK may be novel.

How does this method compare to existing HARQ-ACK feedback techniques in terms of efficiency and reliability?

This article does not provide a direct comparison with existing HARQ-ACK feedback techniques, so it is unclear how this method stacks up against current practices in terms of efficiency and reliability.

What impact could this technology have on the overall performance of wireless communication systems?

While the benefits of this technology are mentioned, the specific impact on the overall performance of wireless communication systems is not explicitly discussed in the article.

Original Abstract Submitted

A method for sending a HARQ-ACK is performed by a user equipment, and includes: determining a first slot set and a second slot set, wherein the first slot set includes slots corresponding to multi-TTI PDSCHs, and the second slot set includes slots in a feedback window corresponding to a HARQ-ACK codebook and the HARQ-ACK codebook is included in a PUCCH for feeding back HARQ-ACKs of the multi-TTI PDSCHs; determining at least one slot group that is in the first slot set and is not in the second slot set and a target slot one-to-one corresponding to each slot group; determining a logical HARQ-ACK on the target slot according to an HARQ-ACK on each slot in each slot group and an HARQ-ACK on the target slot corresponding to each slot group; and sending the HARQ-ACK codebook.
