Methods and apparatuses for switching between asynchronous and synchronous HARQ retransmission modes |
摘要 |
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-S indicates to the transmitting entity to stop the synchronously transmitting retransmissions but to await a scheduling assignment for the retransmission from the receiving entity instead. <IMAGE>
