摘要： An apparatus and method for transmitting/receiving a Hybrid Automatic Repeat reQuest (HARQ) Acknowledge/Negative acknowledge (ACK/NACK) signal in a mobile communication system. The apparatus and method distribute a CDM segment, to which an ACK/NACK signal is mapped, in the frequency domain of an OFDM symbol, and repeatedly transmits the CDM segment, thereby providing diversity gain in the time-frequency domain. Further, the apparatus and method provide a mapping rule for distributing transmit power between OFDM symbols to which the ACK/NACK signal is mapped and transmitted, thereby preventing a particular OFDM symbol power-overload, and thus contributing to improvement of the entire system performance.

摘要： A method for performing cell selection in a mobile communication system and a system therefor. Upon receiving a Multimedia Broadcast and Multicast Service (MBMS) service or a unicast service, a User Equipment (UE) performs cell search separately for each frequency band in an overlapping region between an MBMS-dedicated frequency band and a unicast service-available frequency band. In a first example, the UE allocates different cell identification codes for each cell according to types of the corresponding frequency bands to perform cell search. In a second example, the UE uses the system information broadcasted from the network over P-BCH to indicate whether each cell belongs to the MBMS-dedicated frequency band.

摘要： A method for transmitting and receiving a control channel message in a mobile communication system using multiple antennas is provided. A base station determines whether a common pilot is used or a dedicated pilot is used. It also determines whether a corresponding Multiple Input Multiple Output (MIMO) mode is a Multi-CodeWord (MCW) MIMO mode or a Single CodeWord (SCW) MIMO mode, and determines whether knockdown precoding is used or ready-made precoding is used. The base station generates a control channel message field including a pilot pattern and a precoding type according to the determination results, and transmits the generated control channel message to the terminal. The terminal receives a control channel message transmitted from a base station. The terminal determines whether a common pilot is used or a dedicated pilot is used, whether a corresponding MIMO mode is an MCW MIMO mode or an SCW MIMO mode, and whether knockdown precoding is used or ready-made precoding is used. The terminal analyzes the control channel message field according to the determination results, and determines a data reception method according to the analysis result.

摘要： An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.
