An operating method of a base station for changing a fixed resource allocation to reduce overhead in a mobile communication system includes calculating a total amount of resources allocated to a corresponding subframe in a period of a corresponding fixed allocation resource; when the total amount of the resources allocated to the corresponding subframe is greater than a threshold, temporarily canceling one or more corresponding fixed allocation resources to make the total amount of the resources allocated to the corresponding subframe less than or equal to the threshold; and reallocating the one or more canceled fixed allocation resources according to a corresponding rule.

Resource allocation apparatus and method for reducing overhead in mobile communication system

An apparatus and method for supporting Hybrid Automatic Repeat reQuest (HARQ) in a broadband wireless communication system are provided. A method of performing HARQ by a Mobile Station (MS) in a wireless communication system includes receiving a control message including resource allocation information, decoding the control message, if the decoding is successful, determining whether a previous control message is lost, and if the previous control message is lost, transmitting one of a null signal and a specific indicator through a response channel.

Apparatus and method for supporting hybrid ARQ in broadband wireless communication system

Apparatuses of a base station and terminal in a wireless communication system and their operating methods are provided. An operating method of a base station in a broadband wireless communication system includes determining whether to relocate at least one persistently allocated resource, when it is determined to relocate the at least one persistently allocated resource, relocating the at least one persistently allocated resource, generating a resource relocation Information Element (IE) indicative of the resource relocation using an offset of a Resource Block (RB), and transmitting the resource relocation IE.
