Abstract: PURPOSE: A method and apparatus for controlling power in a wireless communication system is provided to efficiently execute power control and to improve the receiving reliability of a power control bit. CONSTITUTION: A base station transmits a reverse power control bit to a terminal through an F-CPCCH(Forward Common Power Control CHannel) at a specific location of periods PCG1, PCG3, PCG5, etc. The terminal, receiving the power control bit transmitted from the PCG1 of the F-CPCCH, measures the receive power or SNR of the received power control bit and compares it with a preset threshold. In case that the measured result is lower than the threshold, the terminal creates a power control bit to direct the base station to increase transmit power. Then the terminal transmits the power control bit at the PCG2 of an R-PCSCH(Reverse Power Control SubCHannel).

Abstract: An apparatus and a method for transmitting/receiving an F-SCCH(Forward-Shared Control Channel) in a mobile communication system are provided to prevent a waste of resources in configuring a control channel according to the use of codewords when using more than one codeword. A scheduler(901) selects a particular resource block for transmitting a control channel for a packet. An F-SCCH signal generator(914) generates a control channel selectively including one of the first precoding information indicating whether or not the packet has been precoded by using one codeword and the second precoding information indicating whether or not the packet has been precoded by using one or more discriminated codewords. A symbol-resource mapping unit(905) maps the generated control channel to the particular resource block selected by the scheduler. The F-SCCH signal generator generates the control channel by further including identification information of a particular receiving device for receiving the packet, downlink resource block information for transmitting the packet, a TF(Transport Format) information of the packet, and information indicating the number of re-transmissions of the packet.

Abstract: A method and an apparatus for transmitting and receiving feedback information in a MIMO(Multi Input Multi Output) mobile communication system are provided to support a transmit diversity technique and an antenna selection STTD(Space Time Transmit Diversity) technique as well as knockdown precoding and ready-made precoding within the limit of the structure of a feedback channel in a UWB system or the information volume defined in the feedback channel. A mobile terminal determines a precoding method. The mobile terminal judges whether knockdown precoding is used. If so, the mobile terminal judges whether antenna selection precoding, or binary unitary precoding, is appointed to be used. If so, the mobile terminal judges whether to report the CQI(Channel Quality Information) of antenna selection STTD(420). If so, the mobile terminal sets a universal matrix index to indicate the universal matrix of a precoding matrix among the precoder field of an r-bfch(reverse beam index feedback channel) to "1"(422). The mobile terminal writes the antenna selection information of antenna selection STTD, which will be applied in a broadband, in the vector bitmap field of the r-bfch(424). The mobile terminal estimates a CQI value to be applied in the broadband, and writes the estimated value in the CQI filed of an r-mqich(reverse MIMO quality indication channel)(426). Also the mobile terminal writes a preappointed value in the rank field of the r-mqich(428). Then the mobile terminal transmits the feedback information of the r-bfch and the feedback information of the r-mqich(430).

Abstract: A method and a system for operating control channels in a mobile communication system which uses multiple antennas are provided to achieve capacity improvement and efficient resource management by forwarding precoding information or various types of pilot pattern information through shared control channel messages. When a common pilot is used(300), it is judged whether a current mode is an MCW(Multi CodeWord) MIMO(Multiple Input Multiple Output) mode(310). In the MCW mode which uses the common pilot and uses knockdown precoding(320), a specific knockdown precoding method is selected and PFs(Packet Formats) of the MCW MIMO are determined(322). It is determined that an MCW FLAM(Forward Link Assignment Message) is used(324). A mother matrix index is recorded in a pilot/MIMO field(326). A rank is reflected and a layer-classified PF is recorded in a PF field. Other MCW-FLAM fields are recorded(328). In the MCW MIMO mode which uses the common pilot and uses ready-made precoding, a specific ready-made precoding method is selected and PFs of the MCW MIMO are determined(342). It is determined that an MCW FLAM is used(342). A precoding matrix index is recorded in the pilot/MIMO field(346). A rank is reflected and a layer-classified PF is recorded in the PF field. Other MCW-FLAM fields are recorded(348).

Abstract: A method and a system for selecting a cell in a mobile communication system are provided to offer efficient cell selection and cell reselection operation to a terminal in the mobile communication system operating a broadcasting service-dedicated frequency bandwidth, thereby preventing the failure of uplink signaling transmission such as a system access, a routing area update, and a service request, generated as the terminal is camped on at unnecessary frequency bandwidth. A method for selecting a cell comprises the following steps of: determining whether cell searching is needed for a broadcasting service-dedicated frequency bandwidth providing only a broadcasting service; performing the cell searching by using the combination of the PSC and SSC of cells belonging to a frequency bandwidth capable of a unicast service except a combination of a PSC(Primary Synchronization Code) and an SSC(Secondary Synchronization Code) allocated in common to cells belonging to the broadcasting service-dedicated frequency bandwidth when it is determined that the cell searching is not needed; and being camped to a selected cell(861).
