摘要:
A method and apparatus for controlling uplink transmit power in a wireless communication system are disclosed. The method includes determining an uplink transmit power for each of the plurality of transmission channels, and sequentially allocating the determined uplink transmit powers to the transmission channels in a descending order of predetermined priority levels of the transmission channels, within a maximum available transmit power of the user equipment. The priority levels of the transmission channels are predetermined so that control channels, a sounding channel, a data channel, and a bandwidth request channel have priority levels in a descending order.

摘要:
A method for transmitting an information unit of a specific layer above a physical layer through a plurality of frequency allocation bands managed by the specific layer and transmitting control information identifying each of the plurality of frequency allocation bands. The control information includes a second ID into which a first ID has been converted, the first ID identifying each of the plurality of frequency allocation bands in the physical layer, the second ID identifying each of the plurality of frequency allocation bands managed by the specific layer in the specific layer. To accomplish this, a timing offset is applied to the entirety of a frame or to a preamble (synchronous channel) so that the timing offset is used as the ID. Applying a timing offset to the entirety of a frame or to a preamble (synchronous channel) can achieve an advantage of PAPR reduction.

摘要:
A method and device for wirelessly communicating between a mobile communication terminal and a base station, including exchanging one or more resource units between the base station and the mobile communication terminal, each resource unit having 18 subcarriers by a plurality of Orthogonal Frequency Division Multiple Access (OFDMA) symbols. The one or more resource units are permutated using X contiguous subcarriers as a permutation unit in each OFDMA symbol, wherein X is a positive integer that is a multiple of 2 as well as a divisor of 18.
