    Abstract: A method for supporting frequency hopping of a transmission apparatus by a reception apparatus in a wireless communication system supporting Hybrid Automatic Repeat reQuest (HARQ). The method includes determining whether a particular transmission apparatus has a need to perform hopping of allocating a different logical channel every Transmission Time Interval (TTI); and when there is no need to perform hopping every TTI, sending to the transmission apparatus a command to perform hopping every multiple TTIs, and simultaneously signaling information on a number of the multiple TTIs.

    Abstract: An apparatus and method are provided for setting gain factors for dedicated physical channels in a mobile communication system. The UE receives configuration information indicating uplink dedicated physical channel configuration. The UE sets a gain factor of a dedicated physical control channel (DPCCH) to 1 in the case that no DPDCH is configured. The UE calculates a gain factor of a enhanced dedicated physical control channel (E-DPCCH) using the gain factor of the DPCCH.

    Abstract: A method and apparatus for transmitting and receiving signals using a codebook which maps each codeword to at least two different antennas is provided for a MIMO system. A transmission method includes mapping multiple codewords to multiple layers; mapping the multiple layers to multiple antennas using a precoding matrix selected from a rank-3 codebook which is designed to map the codewords to different antennas; and transmitting the codewords through paths formed by mapping the layers and the antennas. The precoding matrix of the rank-3 codebook is designed to equalize transmit power ratios between the antennas. The communication method and apparatus is advantageous to solve the problem of transmit power imbalance among the layers and the problem of performance degradation at the high SNR region in the conventional system using the rank-3 precoding matrices.
