METHOD AND APPARATUS FOR TRANSMITTING HYBRID AUTOMATIC REPEAT AND REQUEST INFORMATION IN A WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18079464 titled 'METHOD AND APPARATUS FOR TRANSMITTING HYBRID AUTOMATIC REPEAT AND REQUEST INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The present disclosure is about a communication method and system that combines 5G technology with Internet of Things (IoT) technology. This allows for higher data rates and supports intelligent services in various fields such as smart home, smart city, and healthcare.
- The method described in the patent application is for a base station to support a handover from an evolved packet system (EPS) to a 5G system.
- The method involves the transmission of HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement) information.
- The UE (User Equipment) detects a PDCCH (Physical Downlink Control Channel) and receives a PDSCH (Physical Downlink Shared Channel) scheduled by the PDCCH.
- The UE determines the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by one slot based on a configured slot pattern and a configured PDCCH monitoring occasion.
- The UE generates an HARQ-ACK codebook according to the determined HARQ-ACK occasion and number of bits, and transmits the HARQ-ACK information.
- This method reduces the number of HARQ-ACK bits to be fed back within each slot, reducing feedback overhead.
- The semi-static change in the number of bits in the generated HARQ-ACK codebook helps avoid confusion between the base station and the UE.
Potential Applications
This technology can be applied in various intelligent services, including:
- Smart home
- Smart building
- Smart city
- Smart car
- Connected car
- Health care
- Digital education
- Smart retail
- Security and safety services
Problems Solved
The communication method and system described in the patent application solve the following problems:
- Supporting higher data rates beyond 4G systems
- Converging 5G communication technology with IoT-related technology
- Reducing feedback overhead in transmitting HARQ-ACK information
- Avoiding confusion between the base station and the UE
Benefits
The benefits of this technology are:
- Higher data rates for improved communication performance
- Support for intelligent services in various fields
- Reduced feedback overhead, improving efficiency
- Avoidance of confusion between the base station and the UE
Original Abstract Submitted
The present disclosure relates to a communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention provides a method of a base station for supporting an inter-system handover from an evolved packet system (EPS) system to a 5th generation (5G) system. The present application provides a method for transmitting HARQ-ACK information, including steps of: detecting, by a UE, a PDCCH and receiving a PDSCH scheduled by the PDCCH; for one slot of one carrier, determining, according to a configured slot pattern and a configured PDCCH monitoring occasion, the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot; and, generating, by the UE, an HARQ-ACK codebook according to the HARQ-ACK occasion and the number of HARQ-ACK bits occupied by the one slot, and transmitting HARQ-ACK information. By the method of the present invention, the number of HARQ-ACK bits to be fed back within each slot is reduced, and the feedback overhead is reduced; moreover, the number of bits of the generated HARQ-ACK codebook changes semi-statically, so that the confusion between a base station and a UE is avoided.
