摘要： An apparatus and method for controlling a digital AGC in a communication system in which power changes significantly from frame to frame. In the digital AGC controlling apparatus, an SNR estimator estimates an uplink SNR of a next frame. A power measurer measures uplink received power of every frame. A gain calculator estimates uplink power of an nth frame using an SNR estimate of an (n−1)th frame received from the SNR estimator and a received power measurement of the (n−1)th frame received from the power measurer, and calculates a gain to be applied to the nth frame in the digital AGC using the uplink power estimate of the nth frame.

摘要： An apparatus and method for changing an uplink power control scheme according to mobile status in a TDD mobile communication system are provided. A subscriber station transmits to a base station a power control change request message including information about a requested power control scheme. Upon receipt of the power control change request message, the base station selects a power control scheme for the uplink of the subscriber station and transmits to the subscriber station a power control change command message including information about the selected power control scheme. The subscriber station extracts, upon receipt of the power control change command message from the base station, the power control scheme information from the power control change command message and selects a power control scheme according to the extracted information.

摘要： A system and method for transmitting control information and data to a mobile station in a communication system using adaptive antenna technology defined in a broadband wireless communication system. In a method for transmitting and receiving information data in the wireless communication system, a base station separates information data to be transmitted into control information and user data, applies different modulation and coding schemes to the control information and the user data, and transmits the information data to an associated mobile station. The mobile station identifies the modulation and coding schemes of the information data received from the base station and demodulates a total of the information data according to the modulation and coding schemes, or independently demodulates the control information and the data according to the modulation and coding schemes.
