摘要： A power control device for a CDMA communication system using different kinds of spreading codes. In the power control device for a base station device, a first channel generator generates a first channel signal by spreading first input data with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller controls power of the first channel signal and a second gain controller controls power of the second channel signal. An adder adds the first channel signal to the second channel signal, and a spreader spreads a signal output from the adder with a pseudo-random noise (PN) code. The base station transmits a response request message to a mobile station via the second channel, and retransmits the response request message after increasing a transmission power of the second channel when a response message is not received from the mobile station.

摘要： A device and method are provided for limiting a power of a signal transmitted through any antenna to a maximum transmission power of the antenna in a TSTD (Time-Switched Transmission Diversity) transmitter of a base station of a mobile communication system. In a TSTD transmitter including at least two antennas and a pattern storage for storing a maximum transmission power limit value and switching patterns of a plurality of user data to be transmitted through the antennas, transmission powers assigned to antennas are measured upon receipt of new user data. A switching pattern is determined such that a value obtained by adding one of the transmission powers to a transmission power of the new user data does not exceed the maximum transmission power limit value.

摘要： A device and method for outer-loop power control in a discontinuous transmission mode in a CDMA mobile communication system. In an outer-loop power control method for a non-frame data transmission period of a dedicated control channel (DCCH) which transmits frame data discontinuously, the signal-to-noise ratio (SNR) of power control bits (PCBs) received at a mobile station from a base station is measured for the frame period, and it is determined whether the frame has errors based on the measured SNR. A closed-loop power control threshold is increased if a frame error exists and decreased if no frame errors exist.

摘要： A channel communication device and method for a mobile communication system using transmission antenna diversity. A base station alternatively transmits signals on a common channel via at least two antennas at first and second intervals. A mobile station estimates a time relationship between the alternatively switched common channel and a user channel and measures the power of the received signals corresponding to the first and second intervals. The mobile station selects an antenna having stronger power by comparing the power of the signal corresponding to the first interval with the power of the signal corresponding to the second interval, and informs the base station of the selected antenna. The base station transmits a dedicated channel via the selected antenna.

摘要： A method for transmitting control data on a downlink and/or uplink channel in a base station and/or mobile station in a mobile communication system. In one embodiment, the base station determines whether there is downlink channel data to transmit to a mobile station. If there is no data to be transmitted over the downlink channel for a predetermined time period, the base station drives a random gating position selector to determine a random gating slot position, gates on the control data at the determined slot position, and gates off the control data at other slot positions. The random position selector determines the gating slot position by calculating a value x by multiplying a system frame number (SFN) of a received signal by a specific integer; selecting n bits starting from a position which is at an x-chip distance from the start point of a scrambling code, which has a period equal to one frame, before a plurality of gating durations used in generating a downlink signal; and determining a gating slot position of a corresponding gating slot group by performing a modulo operation on the selected n bits, where the module operation is by the number of slots in a gating slot group.
