METHOD AND APPARATUS FOR PERFORMING HYBRID AUTOMATIC REPEAT REQUEST OPERATION IN AN ASYMMETRIC MULTICARRIER COMMUNICATION NETWORK ENVIRONMENT

WIPO Patent Application WO/2014/061998

A1

The present invention provides a method and system for performing Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment. In one embodiment, a method includes receiving resource allocation information from a base station. The method also includes transmitting the HARQ packet to the base station in a transmit time interval (TTI) corresponding a first or second partition of an uplink allocation interval on a second carrier. The method further includes receiving HARQ feedback information corresponding to a previous HARQ packet transmission. Furthermore, the method includes determining a TTI in a subsequent uplink allocation interval based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. Moreover, the method includes transmitting the HARQ packet to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.
