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.

1. A method, comprising:
transmitting, by a network device, data in a first transmission; receiving, by the network device, acknowledgement information for Hybrid Automatic Repeat-Request pursuant to uplink-downlink subframe configurations 0 or 6 in Time-Division-Duplex mode for LTE; determining, by the network device, a subframe for a re-transmission of the data according to a process for Hybrid Automatic Repeat-Request, wherein the subframe for the re-transmission is determined such that interference from a neighboring cell is of a same type during the first transmission and during the re-transmission, wherein the type of interference comprises uplink or downlink interference; and transmitting, by the network device, said data in the re-transmission in the determined subframe, wherein, based on the determined subframe, the re-transmission associated with the 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.
