An apparatus and method for maintaining backward compatibility with a narrow-band wireless communication system in a wide-band wireless communication system is provided. The base station comprises a scheduler, a control information generator, a resource mapping unit and a transmitter. The terminal comprises a resource allocation information checking unit, a receiver and a transmitter.

Apparatus and method for frame structure in wide-band wireless communication system

A method of signal transmission/reception by a transmitter in a wireless mobile communication system is provided. The method includes determining a signal transmission/reception corresponding relation between a downlink and an uplink of the wireless mobile communication system using a super-frame, the super-frame including at least one frame, said at least one frame including at least one downlink sub-frame and at least one uplink sub-frame, the signal transmission/reception corresponding relation enabling each sub-frame within a link including fewer sub-frames to correspond to at least one sub-frame within a link including more sub-frames when the downlink and the uplink of the wireless mobile communication system include different numbers of sub-frames, wherein the signal transmission/reception corresponding relation is also determined when the downlink and the uplink of the wireless mobile communication system include a same number of sub-frames, and transmitting and receiving signals to and from a receiver through at least one downlink sub-frame and at least one uplink sub-frame according to the determined signal transmission/reception corresponding relation.

Method for signal transmission/reception based on HARQ scheme in wireless mobile communication system

A method for performing a Hybrid Automatic Repeat reQuest (HARQ) operation in a wireless mobile communication system that uses Frequency Division Duplex (FDD) or Time Division Duplex (TDD) frames each having a plurality of subframes for communication are provided, in which an HARQ timing including a transmission time of a data burst and a transmission time of an HARQ feedback, for DL HARQ is determined according to data burst assignment information transmitted in a #l DownLink (DL) subframe of a #i frame, and an HARQ operation is performed according to the determined HARQ timing. At least one frame index and at least one subframe index that represent the HARQ timing are determined by using l and i.

Method for performing hybrid automatic repeat request operation in a wireless mobile communication system

An apparatus and method for notifying a change of system control information in a wireless communication system are provided. The method includes, changing a Group Configuration Change Counter (GCCC) and upon change of a Secondary-Super Frame Header/Sub-Packet1 (S-SFH/SP1) whose transmission period is changeable within a range of one or more super frames, changing the GCCC and information representing the change of the common control message upon change of at least one common control message, and transmitting the GCCC and the information representing the change of the at least one common control message.

Apparatus and method for notifying change of system control information in a broadband wireless communication system

A system and method are disclosed for transmitting/receiving a signal in a communication system in which a first communication system and a second communication system coexist, the second communication system being evolved from the first communication system and being capable of using a control signal and a broadcast signal used in the first communication system. The method of transmitting a signal includes the steps of transmitting a first message including common control information and frame control information for the first communication system in a first frame, transmitting a second message including common control information and frame control information for the second communication system in a second frame, and signaling location information of the transmitted second message in the second frame.

System and method for transmitting/receiving signal in communcation system

Disclosed is a method of transmitting common control information by a base station in a communication system including a first communication system and a second communication system different from each other. In the communication system, a frame for carrying the common control information includes an uplink sub-frame and a downlink sub-frame, each of which includes a resource allocation area for the first communication system and a resource allocation area for the second communication system. The method includes: configuring the common control information to be received by a mobile station belonging to the second communication system; and transmitting the common control information through the resource allocation area for the second communication system included in one of the uplink sub-frame and the downlink sub-frame.
