    摘要： Disclosed are a method and an apparatus for determining rate matching parameters for transport channels in mobile telecommunication system. The apparatus and method include determining first physical channel bit sizes usable in transmitting at least one first transport channel not supporting hybrid automatic repeat request (HARQ) and at least one second transport channel supporting the hybrid automatic repeat request, determining if there is at least one second physical channel bit size in the first physical channel bit sizes, the second physical channel bit size allowing transmission for a size of coded bits corresponding to the first transport channel and a size of coded bits corresponding to the second transport channel based on rate matching and puncturing, reducing the size of the coded bits corresponding to the second transport channel when the second physical channel bit size is not included in the first physical channel bit sizes, returning to the step of determining if there is at least one second physical channel bit size after the size of the coded bits corresponding to the second transport channel is reduced, and when there is at least one second physical channel bit size, selecting one second physical channel size based on at least one second physical channel bit size as a rate matching parameter for the first transport channel and the second transport channel.

    摘要： A method is provided for transmitting a control channel for resource allocation to a terminal by a base station in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system. An additional resource allocation indicator is set indicating whether the number of consecutive resource block sets allocated to a terminal is greater than one. A reference control channel is generated including reference resource allocation information for a first consecutive resource block set and the set additional resource allocation indicator. An additional control channel using additional resource allocation information is generated, when there are one or more additional consecutive resource block sets. At least one of the generated reference control channel and the generated additional control channels is encoded before transmission.

    摘要： Disclosed is a method and an apparatus for multiplexing and transmitting/receiving an ACK/NACK resulting from use of a HARQ scheme in an OFDMA system. Frequency and code multiplexing methods are combined with regard to the ACK/NACK to reduce signaling overhead. Frequency multiplexing is conducted by using the MCS level adopted by scheduling channels to improve the ACK/NACK transmitting performance, and code multiplexing is conducted to allocate ACK/NACK resources by using the index of the scheduling channels.

    摘要： Disclosed is an apparatus and method for transmitting the synchronization signal in an Orthogonal Frequency Division Multiplexing (OFDM) based cellular system. The cell search process widely used in the OFDM based cellular system is divided into two steps for obtaining the frame timing synchronization and obtaining the cell-specific scrambling code. When designing the channel for obtaining the frame timing synchronization and the channel for obtaining the cell-specific scrambling code, different frequency reuse factors are applied to the synchronization channels of different steps according to the characteristics of each synchronization obtainment step in order to improve the performance of each step.
