SYSTEM AND METHOD FOR DOWNLINK PHYSICAL INDICATOR CHANNEL MAPPING WITH ASYMMETRIC CARRIER AGGREGATION |
摘要 |
A base station that communicates with a plurality of subscriber stations in a wireless communications network is configured to allocate downlink physical channel resources in asymmetric carrier systems. The base station includes a transmitter configured to allocate a set of Physical Hybrid Automatic Repeat Request Indicator Channel (PHICH) resources in a downlink carrier. The transmitter can inform, via an uplink grant, a subscriber station regarding one or more PHICH resources from the allocated set of PHICH resources. The base station also includes a receiver that can receive a data communication from the subscriber station within PRBs in a number of uplink carriers that correspond to PRB indices included in the uplink grant. The transmitter can transmit an Acknowledgement/Negative Acknowledgement on the allocated PHICH resources in the downlink carrier such that a PHICH resource is defined by the PRB index and at least one offset value. |
