Title:
METHOD, DEVICE, APPARATUS, AND STORAGE MEDIUM FOR DETERMINING FEEDBACK TIME SEQUENCE
Document Type and Number:
Japanese Patent JP2021036726
Kind Code:
A
Abstract:
To provide a method and a device which determines feedback timing in a hybrid automatic resending request.SOLUTION: The present invention provides a method and a device which determines feedback timing in a hybrid automatic resending request. The method includes the steps of: determining a composition of a TDD frame structure used now, and the composition of the TDD structure including an up down-link composition and a special sub frame constitution; determining size of a transmission-time interval (TTI) used now; on the basis of the composition of the TDD frame structure, and the size of the TTI, determining relative position relation between data transmission TTI in a HARQ process and its feedback TTI, or relative position relation among a first time transmission TTI, a feedback TTI, and a resending TTI. The Example of the present invention further discloses a communication device and a storage medium.SELECTED DRAWING: Figure 2b
