Claim 3:
4. The method of claim 1 wherein transmitting the HARQ feedback comprises transmitting the HARQ feedback using a format selected from a group consisting of:
a format based on physical downlink control channel (PDCCH) or extended PDCCH (EPDCCH);
a format comprising a physical layer channel using one interlace for multiple signals;
a format comprising a physical layer channel using one interlace for multiple signals in a downlink partial subframe;
a format based on Physical HARQ Indicator Channel (PHICH);
a format based on PHICH in combination with bit compression to reduce a size of the bit map; and
a format based on an implicit ACK/NACK via Control Channel Element (CCE) indices of PDCCH transmissions sent to wireless devices for downlink scheduling where a time gap between an autonomous uplink transmission and a PDCCH transmission is 1 ms or more.
