Abstract
A method and apparatus for resource allocation for half duplex frequency division duplexing in a wireless communication system is provided. Fixed or variable HARQ timing of greater than 5 subframes may be implemented. Acknowledgements for multiple downlink (uplink) transmissions can be bundled into a single acknowledgement transmitted on an uplink (downlink) control channel. Bundled acknowledgements for downlink transmissions may also be provided. Variable lead time cross subframe scheduling may be provided in which the number of subframes of delay between an uplink or downlink grant and the corresponding scheduled uplink or downlink transmission changes based on other scheduled events and/or half-duplex transceiver availability in the appropriate mode. The scheduling may select the earliest available subframe after a minimum delay. Uplink grant bundling may also be performed, in which multiple uplink grants are transmitted via a single grant indication.
