Document Type and Number:
Japanese Patent JP2007523529
Kind Code:
A
Abstract:
The present invention relates to method for controlling the transmission timing of data retransmissions in a wireless communication system wherein a HARQ retransmission protocol, is used to retransmit data from a transmitting entity to a receiving entity via a data channel. Further the present invention relates to a base station, a mobile terminal and a communication system employing the present invention. To overcome problems resulting from synchronous retransmissions in interference critical situations, the present invention introduces additional feedback signaling to a new HARQ protocol. The new NACK-H indicates to the transmitting entity to postpone the synchronous retransmissions by an additional amount of time instead of transmitting the retransmission at a predetermined point in time after the reception of a negative feedback message.
