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 (DATA1) with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data (DATA2) with a quasi-orthogonal code. The second channel signal has a gain higher than that of the first channel signal. A first gain controller (17) controls power of the first channel signal and a second gain controller (18) controls power of the second channel signal. An adder (20) adds the first channel signal to the second channel signal, and a spreader (21) 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 base station and a mobile station for a CDMA communication system intermittently exchange data on a power control group unit or time slot unit in a control hold state to minimize interference. To this end, during channel transmission, the system intermittently transmits a reverse pilot channel signal in the control hold state; upon activation of a reverse dedicated control channel, transmits a normal pilot channel signal which is first generated after activation of the reverse dedicated control channel; and then transmits the reverse dedicated control channel.

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 synchronization (sync) code communication device for an CDMA communication system. A base station sync code transmission device comprises a primary sync code transmitter and a secondary sync code transmitter. The primary sync code transmitter is for generating and then transmitting a primary sync code at a first location in a transmission frame. The primary sync code is for acquiring synchronization at a starting point of a frame and the frame is equal to one period of a spreading code. The secondary sync code transmitter is for generating and then transmitting a secondary sync code at a second location in a frame. The secondary sync codes are assigned to base station groups, one to a group. A mobile station sync code receiving device comprises a primary sync code acquisition decider and a base station group decider. The primary sync code acquisition decider is for acquiring a primary sync code received at a first location in a frame, and then acquiring synchronization at a starting point of a frame. The base station group decider is enabled upon acquisition of the primary sync code, receives a secondary sync code transmitted at a second location in the frame, and then determines the base station group to which the transmitting base station belongs.

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.
