Apparatus and method for supporting frequency overlay in broadband wireless communication system

摘要

A broadband wireless communication system is provided. A sending apparatus in the broadband wireless communication system includes a controller for distributing packets to a plurality of processors to transmit the packets in a multi-Frequency Allocation (FA) access mode; the plurality of the processors for processing the packet provided from the controller in a Media Access Control (MAC) layer; and a plurality of senders for encoding the packets provided from the corresponding processors in a physical layer and transmitting a signal generated through the physical layer encoding.

1. An apparatus in a wireless communication system, the apparatus comprising:
a controller for distributing packets, to be transmitted to a serving Base Station (BS), to a plurality of processors to transmit the packets in a multi-Frequency Allocation (FA) access mode; the plurality of the processors for establishing a plurality of connections for each of FAs with the serving BS, and generating Media Access Control (MAC) Protocol Data Units (PDUs) for each of the FAs, wherein the FAs include a first FA and at least one remaining FA; and a plurality of senders for encoding the MAC PDUs provided from the corresponding processors for each of the FAs and transmitting signals to the serving BS, wherein the controller determines to hand over to a target BS, switches to a single FA access mode by releasing at least one connection for each of the at least one remaining FA, hands over to the target BS from the serving BS at the first FA, and switches to the multi-FA access mode by establishing at least one connection for each of the at least one remaining FA with the target BS.
