    摘要: A method and apparatus for mapping coded data symbols to resources in a mobile communication system. An S/P converter converts a serial signal including user data or control information into a plurality of parallel signals. A DFT unit performs Discrete Fourier Transform (DFT) on the parallel signals output from the S/P converter. A controller controls the DFT unit so that among the signals output from the S/P converter, a control channel is mapped in the maximum available resources to which the control channel can be mapped, among the resources included in a resource block, and data symbols are mapped to the remaining resources, except for the maximum available resources to which the control channel can be mapped. A subcarrier mapper allocates the signals output from the DFT unit to subcarriers. An RF processor converts a signal output from the subcarrier mapper into a radio signal.

    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: A mobile communication system using an enhanced uplink dedicated transport channel transmits data at a relatively low effective data rate through non-scheduled transmission. Data transmission time intervals for user equipments (UEs) have different values in the non-scheduled transmission and therefore uplink interference is reduced. An non-scheduled transmission period N and the number of non-scheduled transmissions k are determined such that each UE performs the non-scheduled transmission. A Node B and each UE are notified of possible non-scheduled transmission time intervals based on the determined non-scheduled transmission period N and the determined number of non-scheduled transmissions k through signaling. The UE transmits the uplink data without the Node B's scheduling at the possible non-scheduled transmission time intervals.

    摘要: Methods and apparatuses are described for a Node B to transmit Reference Signals (RS) from multiple antennas to enable User Equipments (UEs) to perform demodulation of received information signals and to estimate Channel Quality Indication (CQI) metrics. To minimize overhead and enable backward compatible operation with legacy systems, RS from a first set of Node B antennas are transmitted in every transmission time interval and substantially over the whole operating BandWidth (BW). RS from a second set of Node B antennas serving for CQI estimation are periodically transmitted, substantially over the whole operating BW, with transmission period informed to UEs through broadcast signaling by the Node B and starting transmission sub-frame determined from the identity of the cell served by the Node B. RS from the second set of antennas, and new RS from the first set of antennas, serving for demodulation of information signals have substantially the same BW as the information signals which can be smaller than the operating BW.

    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.
