A retransmission control method, a transmitter and a receiver. The method comprises the steps of receiving, at a MIMO transmitter, a NACK signal indicating an unsuccessful decoding of a coded data packet at a MIMO receiver; receiving a reliability measure associated with one or more transmitted spatial data streams for the unsuccessfully decoded data packet; comparing the reliability measure with at least one predetermined threshold; and selecting a retransmission protocol based on the comparison of the reliability measure with the at least one predetermined threshold.

Retransmission control technique

A method is provided for determining whether transmission signals are present in received signals, the method comprising: receiving a first signal via a first radio resource; receiving a second signal via a second radio resource; determining whether a first transmission signal is present in the received first signal based on the received second signal; and determining whether a second transmission signal is present in the received second signal based on the received first signal.

Method, device and computer readable medium for determining whether transmission signals are present in received signals

A method for retransmission of data in a multiple input multiple output (MIMO) system, the method comprising space-time block code (STBC) encoding multiple data streams including one or more retransmission data streams using a STBC matrix, the STBC matrix multiplying at least one of the retransmission data streams with respective variable weighting factors.

Retransmission of data in a multiple input multiple output (MIMO) system

A method for re-transmission in a multiple-input multiple-output (MIMO) communication system, the method comprising: performing spatial mapping of one or more retransmitted data streams and one or more newly transmitted data streams, wherein the spatial mapping comprises switching bits between the re-transmission data streams and the new transmission data streams.
