Abstract
The present invention relates to a retransmission control method and device in user equipment supporting uplink spatial multiplexing. The method includes the steps of detecting an uplink (UL) resource grant on a physical downlink control channel (PDCCH) (102), the uplink grant being valid for at least one block of transport (TB), to detect that at least one transport block is not validated (103), so that no resource grant is associated with said transport block or blocks, to interpret (106) the transport blocks not validated as an acknowledgment, ACK, of a previous transmission corresponding to said non-validated transport block independently of the indication that is received on the receive state information return channel for said transmission previous.
