Enhanced TDD UL HARQ timeline for UL-DL coexistence scenario

摘要

The present invention provides a method, apparatus and a program relating to an enhanced TDD UL HARQ timeline for UL-DL coexistence scenario. The present invention includes transmitting data in a first transmission, receiving acknowledgement information for Hybrid Automatic Repeat-Request pursuant to uplink-downlink configurations 0 or 6 in Time-Division-Duplex mode for LTE, determining the timing of a second transmission associated with a process for HARQ and transmitting data in a second transmission in the subframe according to the determined timing, wherein a second transmission associated with a process for Hybrid Automatic Repeat-Request is performed in a protected subframe if the first transmission associated with said process is performed in a protected subframe.
