摘要:
A method for transmitting/receiving data in a communication system using multiple frequency bands. The transmission method includes fragmenting a desired transmission Service Data Unit (SDU) in units of Packet Data Units (PDUs); and transmitting the fragmented PDUs over at least two frequency bands among the multiple frequency bands. Each of the multiple frequency bands is supported by a system having backward compatibility with a legacy system. The reception method includes decrypting a wireless resource (MAP) allocated separately for each of the frequency bands to extract fragment information therefrom; and receiving PDUs over the frequency bands separately, and restoring the SDU according to fragment information corresponding to the corresponding frequency band.

An apparatus and method for periodically allocating uplink resources in a broadband wireless communication system are provided. Base Station (BS) includes a resource allocator for allocating periodic uplink (UL) resources to a terminal, a control information generator for generating a resource allocation message for the terminal using resource allocation information from the resource allocator, generating and outputting control information including the generated resource allocation message, and a transmitter for transmitting the control information from the control information generator.

Provided is an apparatus and method for allocating resources in a wireless communication system. In method, whether there are one or more mobile stations periodically transmitting or receiving data of the same size, among mobile station to be provided with a service is determined if a predetermined region of a frame is set as a fixed region to be allocated to mobile stations that periodically transmit or receive data of the same size. The channel states of the mobile stations are detected if there are mobile stations periodically transmitting or receiving data of the same size. Resources of the fixed region are allocated according to the channel states of the mobile stations. The resource allocation information is transmitted to the mobile stations.

An apparatus and method for UpLink (UL) radio resource allocation in a wideband wireless communication system are provided. In a method of operating a Relay Station (RS) for UpLink (UL) radio resource allocation in a wideband wireless communication system, the method includes relaying to a Base Station (BS) a resource request message of at least one or more Mobile Stations (MSs); receiving data from the at least one or more mobile stations; if the received data is non-real time traffic, queuing the data received from the mobile stations according to a traffic type; and requesting the base station to allocate necessary radio resources by checking a queue status. Accordingly, a delay can be reduced when the UL resource is allocated to an relay station for real time traffic.

Provided is a method for a MIMO TX mode feedback operation of a user terminal in a MIMO communication system. The user terminal receives allocation information about a feedback channel and a feedback period of a MIMO TX mode from the base station. The user terminal determines whether the current time point is the feedback period of the MIMO TX mode. The user terminal selects a first MIMO TX mode according to channel quality information of a signal received from the base station, at the feedback period of the MIMO TX mode. The user terminal detects a MIMO TX mode of first data received from the base station. The user terminal compares the selected first MIMO TX mode with the detected MIMO TX mode of the first data.
