  • Publication number: 20160309479
    Abstract: Methods and apparatus are provided for transmitting and receiving data in a wireless communication system. Resource allocation information is received and hopping-related information is identified. A resource for transmitting data is determined based on the resource allocation information and hopping-related information, and data is transmitted on the determined resource. A sub-band is determined from a plurality of sub-bands based on the first hopping parameter and a resource in the determined sub-band is determined based on the second hopping parameter.

  • Patent number: 8953552
    Abstract: A method is provided for allocating resources of a control channel in a mobile communication system using Orthogonal Frequency Division Multiplexing (OFDM). The method includes, when a time index and a frequency index of available Resource Elements (REs) are defined as l and k, respectively, dividing the available REs in a two-dimensional structure of (k, l); and time-first-allocating each RE to a plurality of RE groups while increasing the time index l for each frequency index k from an initial value up to a predetermined range.

  • Patent number: 8411660
    Abstract: A method for allocating resources in a wireless communication system using Frequency Division Multiple Access (FDMA). The method includes dividing entire frequency resources into sub-bands each having a number of sub-channels, setting at least one sub-channel in each of the sub-bands as a wide-band resource, and providing the sub-band and wide-band information to mobile stations; and determining one of the sub-band resource and the wide-band resource as an allocated resource according to channel condition with a particular mobile station when there is a need for communication with the mobile station.

  • Patent number: 8362238
    Abstract: The present invention relates to a process of preparing a highly pure tacrolimus, which comprising a pre-purification process carried out by means of crystallization, and particularly to a process of preparing a highly pure tacrolimus, which comprises a pre-purification process comprising the steps of (a) extracting mycelia cake collected by filtering a tacrolimus-containing oily compound with an organic solvent, (b) concentrating the extract under reduced pressure and (c) crystallizing the concentrate. In addition, a highly pure tacrolimus can be obtained by dissolving the pre-purified crystals in an organic solvent, passing through the solution in an adsorption resin and concentrating the eluate under reduced pressure, followed by crystallization. According to a process of the present invention, Tacrolimus as pure as appropriate for a pharmaceutical purpose can be prepared by a simple process and at a relatively low cost.
