METHOD AND APPARATUS FOR HARQ-ACK TRANSMISSION IN TRAFFIC ADAPTIVE TDD SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18076773 titled 'METHOD AND APPARATUS FOR HARQ-ACK TRANSMISSION IN TRAFFIC ADAPTIVE TDD SYSTEM

Simplified Explanation

The abstract describes a method and apparatus for transmitting feedback information in a traffic adaptive TDD system using HARQ-ACK. The method involves receiving downlink control information on a PDCCH, which includes a resource indicator for transmitting the HARQ-ACK information and power control information for a UE. The transmission power of the UE is determined based on the power control information, and the HARQ-ACK information is transmitted using the PUCCH resource and the determined transmission power.

  • The method and apparatus enable the transmission of HARQ-ACK feedback information in a traffic adaptive TDD system.
  • The downlink control information received on the PDCCH includes a resource indicator for transmitting the HARQ-ACK information and power control information for the UE.
  • The transmission power of the UE is determined based on the power control information, ensuring efficient power usage.
  • The HARQ-ACK information is transmitted using the PUCCH resource and the determined transmission power, ensuring reliable communication.

Potential Applications

  • This technology can be applied in wireless communication systems using traffic adaptive TDD, where efficient and reliable transmission of feedback information is crucial.
  • It can be used in various applications such as cellular networks, IoT devices, and wireless communication between vehicles.

Problems Solved

  • The method and apparatus solve the problem of transmitting HARQ-ACK feedback information in a traffic adaptive TDD system.
  • It addresses the challenge of efficiently determining the transmission power of a UE based on power control information.
  • It solves the issue of reliably transmitting the HARQ-ACK information using the appropriate PUCCH resource.

Benefits

  • The method and apparatus enable efficient and reliable transmission of HARQ-ACK feedback information.
  • It optimizes power usage by determining the transmission power of the UE based on power control information.
  • The technology ensures reliable communication by transmitting the HARQ-ACK information using the appropriate PUCCH resource.


Original Abstract Submitted

A method and an apparatus are provided for HARQ-ACK feedback information transmission in a traffic adaptive TDD system. The method includes receiving, on a physical downlink control channel (PDCCH), downlink control information for scheduling a physical downlink shared channel (PDSCH), wherein the downlink control information includes a resource indicator indicating at least one physical uplink control channel (PUCCH) resource for transmitting the HARQ-ACK information and power control information for controlling transmission power of a UE; determining the transmission power of the UE based on the power control information; and transmitting the HARQ-ACK information based on the at least one PUCCH resource and the determined transmission power.
