Apparatus and method for circuit mode resource allocation in broadband wireless access (bwa) system

A method for a periodic resource allocation to a terminal in a Broadband Wireless Access (BWA) system comprising:

• receiving a first resource allocation message which comprises a currently used slot bitmap information of a circuit mode region in a frame;
• receiving a second resource allocation message which comprises resource allocation information;
• and
• locating a resource allocated to the terminal using the currently used slot bitmap information and the resource allocation information with respect to currently unused slots in the circuit mode region,
• wherein the currently used slot bitmap information indicates whether each slot in the circuit mode region is used.

An apparatus for periodic resource allocation of a base station in a Broadband Wireless Access (BWA) system comprising:

• a scheduler for allocating resources to one or more terminals with respect to currently unused slots in a circuit mode region according to currently used slot bitmap information of the circuit mode region in a frame;
• and
• a MAP generator for generating a first resource allocation message which comprises the currently used slot bitmap information and a second resource allocation message which comprises information relating to the resource allocation,
• wherein the currently used slot bitmap information indicates whether each slot in the circuit mode region is used
• wherein the MAP means resource allocation information to indicate data burst transmitted in the current frame.

An apparatus for periodic resource allocation to a terminal in a Broadband Wireless Access (BWA) system comprising:

• a Radio Frequency (RF) receiver for converting a signal received via an antenna to a baseband signal;
• a physical layer decoder for converting the signal output from the RF receiver in a physical layer;
• and
• a MAP analyzer for receiving a first resource allocation message which comprises a currently used slot bitmap information of a circuit mode region in a frame, and a second resource allocation message which comprises resource allocation information through the physical layer decoder, and locating a resource allocated to the terminal using the currently used slot bitmap information and the resource allocation information with respect to currently unused slots in the circuit mode region,
• wherein the currently used slot bitmap information indicates whether each slot in the circuit mode region is used,
• wherein the MAP means resource allocation information to indicate data burst transmitted in the current frame.
