摘要:
A method and system for transmitting and receiving resource allocation information in a communication system are disclosed, in which an Relay Station (RS) receives a resource allocation information message from a Base Station (BS), detects a first resource allocation information from the resource allocation information message, and detects a second resource allocation information intended only for the RS using the first resource allocation information.

Provided is a transmitter apparatus in a MIMO wireless communication system. The transmitter apparatus includes a controller and a space-time encoder. The controller generates a space-time encoding code according to a multiplexing order, the number of transmitter antennas, and the number of receiver antennas. The space-time encoder space-time-encodes a TX signal using the generated space-time-encoding code.

A method for transmitting and receiving data in a communication system. The method generates a frame for mapping each of multiple communication service modes of a base station providing the multiple communication service modes to a user terminal, in units of subframes each having a time interval and a frequency band. The method includes estimating a communication service mode supporting an optimal service among the multiple communication service modes provided by the base station supporting the multiple communication service modes, and sending to the base station a random access message for access to the base station over a shared channel.

Provided are a relaying method and system in a communication system having a BS, a MS for communicating with the BS, and an RS for relaying signals between the BS and the MS, in which the RS receives a first pilot sequence from the BS, replaces the first pilot sequence with a second pilot sequence, and transmits the second pilot sequence to the MS. Here, a partial cross correlation between the first and second pilot sequences is always ‘0’.

A method and apparatus for transmitting localized-type resource allocation information by a base station in a communication system. The base station transmits allocation information for localized-type resources using multiple mini-resource blocks. The mini-resource blocks are generated by dividing the localized-type resources into first localized-type resources for mini-resource block generation, and second localized-type resources, and dividing the first localized-type resources by a predetermined number.
摘要:
An apparatus and method for implementing SDMA in a multi-user multi-antenna system are provided, in which SDMA users are selected from among total users according to channel state information of the total users, and the number of transmission streams to be allocated to each of the SDMA users is determined by a tree search method.
摘要:
An Apparatus and a method for interference cancellation in a wireless communication system are provided. When a resource of an Interference Cancellation (IC) zone is allocated to a terminal traveling in a service coverage, resource allocation information relating to an IC zone of neighbor cells is gathered. Resource allocation information is generated relating to the resource allocated to the terminal comprising resource allocation information of the IC zone of the neighbor cells. The resource allocation information relating to the resource allocated to the terminal is transmitted to the terminal. Accordingly, when the interference is present, the interference cancellation is carried out to reduce the load on the terminal and enhance the reception performance.

An apparatus and method for renewal-based resource allocation in a Broadband Wireless Access (BWA) system are provided. A Base Station (BS) allocates resources to a Mobile Station (MS) by resource allocation information. It is determined whether the MS requires continuous resource allocation or whether the MS does not have transmission data temporarily, when a resource allocation duration for downlink resources allocated to the MS has expired. One of resource allocation termination, resource allocation renewal, and temporary resource lending to another MS is performed according to the determination. Information for updating the resource allocation information is transmitted to the MS.

Apparatus and method for allocating a Channel Quality Information CHannel (CQICH) in a wireless communication system are provided. The method includes determining CQICH patterns required for users using information of one or more users to which CQICH resources are to be allocated, and selecting a CQICH pattern block, including all of the determined CQICH patterns, from among a plurality of pre-generated CQICH pattern blocks; and allocating CQICH sub-blocks corresponding to the users' required CQICH patterns using resource layout information of the CQICH sub-blocks corresponding to the CQICH patterns of the selected CQICH pattern block, and transmitting CQICH allocation information to a Mobile Station (MS).
摘要:
Provided is an apparatus and method for resource allocation for multicast data in a broadband wireless access system. In the method, multicast packets are scheduled. Thereafter, a resource allocation message for the scheduled multicast packets divided into a second multicast resource allocation message including information of a user group using a multicast ID and a first multicast resource allocation message including information transmitted in common to users of the user group, and the corresponding message including changed information is transmitted for a change of information. Therefore, it is possible to reduce a waste of resource that is due to the duplicate transmission of some fields of resource allocation information about multicast data.
