摘要:
The present invention relates to a terminal device and method for controlling uplink transmission power for initial data transmission after network entry in a wireless communication system. The terminal device according to the present invention comprises a processor and a transmitter. The processor determines an initial offset value for determining uplink transmission power for an initial data transmission using the power value ultimately used in an initial ranging transmission and the number of initial ranging subcarriers, and determines an uplink transmission power value for an initial data transmission using the determined initial offset value. The transmitter transmits initial data to a base station with the determined uplink transmission power value for an initial data transmission.

A method and device for determining a number of fast feedback channel (FFBCH) in a wireless communication system supporting a first and second wireless communication scheme. The method includes determining the number of FFBCH (NFFB) in an uplink subframe by using the following equation: NFFB=Nfb×NFB−k×NHFB/6. Here, Nfb=3 or 4, NFB is a number of distributed logical resource units in the uplink subframe reserved for feedback channels, k is a value determined according to a ratio of a number of downlink subframes to a number of uplink subframes in a frame, and NHFB is a value defined in a secondary superframe header sub-packet 1 information element.

Disclosed are a device and method for transmitting/receiving control information in a wireless communication system simultaneously supporting a first wireless communication method and a second wireless communication method. In the base station device transmitting control information according to the present invention, the transmitter may transmit second control information including information on the resource size of the first control information for uplink power control. At this point, the resource size of the first control information is determined by the number of uplink subframes and downlink subframes available in one frame, the number of fast feedback channels (FFBCHs), and a ceil function rounding off to a whole number.

Disclosed are a terminal for controlling uplink transmission power and an uplink transmission power control method in a wireless communication system. In the terminal according to the present invention, if the total sum of uplink transmission power values respectively determined for a plurality of transmission channels is greater than the maximum transmission power value of the terminal, a processor can allocate respective uplink transmission power values sequentially in accordance with priority rankings across the plurality of transmission channels which have been determined in advance, starting from the transmission channel corresponding to the highest priority ranking. An emitter can simultaneously transmit the plurality of transmission channels with each of the allocated uplink transmission power values.
