  • METHODS, APPARATUS AND COMPUTER PROGRAMS FOR CONTROLLING RETRANSMISSIONS OF WIRELESS SIGNALS
    Publication number: 20140086175
    Abstract: A wireless device operates in a wireless cellular network under control of a network control apparatus. The wireless device transmits a signal to the network control apparatus. The wireless device receives from the network control apparatus a negative acknowledgement of receipt of the signal in accordance with an automatic repeat request process, The negative acknowledgement indicates that the signal was not received or was not received correctly by the network control apparatus. The wireless device either does not retransmit the signal to the network control apparatus or delays the retransmission of the signal to the network control apparatus in order to avoid conflict with a device-to-device discovery signal being sent by another wireless device.
