This disclosure relates to performing retransmissions in a wireless communication system by a wireless device. A wireless device may receive a first transmission of a data frame according to a wireless communication technology. The wireless device may attempt to decode the data frame. It may be determined that attempting to decode the data frame is unsuccessful. A retransmission of the data frame may be received at a retransmission interval after the first transmission of the data frame. The retransmission interval may be less than a minimum interframe interval for contending for medium access for new transmissions according to the wireless communication technology.
