摘要： An active set control method for handover operation in a CDMA communications system in which propagation conditions of an uplink channel and a downlink channel for an access link of cell are different, provides that when a cell is deleted from the active set based on a request of a base station which has detected a degraded signal of the uplink channel, a predetermined period of time is to be counted for inhibiting addition of the same cell in the active set based on a request of a mobile terminal which has detected a satisfied signal of the downlink channel, thereby preventing the deletion and addition of the cell in the active set from successive operations in a short time.

摘要： To achieve the optimal power control of a system in an MIMO communication method. When decoding in accordance with a receiving algorithm of the MIMO communication method in plural receivers, each receiver acquires the reception power level of a received signal from a transmitter paired with the receiver, and generates a transmitter power control signal based on a comparison result of comparing the reception power with a predetermined value. For example, if the reception power level is lower than the predetermined value, a transmitter power control signal of instructing to increase the transmitter power is generated, or otherwise, a transmitter power control signal of instructing to decrease the transmitter power is generated. The generated control signal is transmitted from the receiver to the transmitter paired with the receiver. Each transmitter controls the transmitter power in accordance with the received control signal.

摘要： Each base station measures the reception states of an uplink high-speed signal from mobile terminals and periodically reports the measurement results to a radio network controller (RNC). The RNC determines cells that are to be deleted from an active set based on the reception states (for example, the reception SIR) that are reported from each base station. The RNC transmits to one base station and mobile terminal a radio line release request for releasing the radio line of the uplink high-speed signal that has been set to a cell that has been determined as a cell to be deleted from the active set. The base station and mobile terminal that have received the radio line release request from the RNC each release the radio line, whereby the cells of other base stations are eliminated from the active set.

摘要： A HSDPA type mobile communication system includes a base station and a mobile station. The base station sets the uplink control channel with the mobile station to transmit a pilot signal. The mobile station measures a reception quality of the pilot signal to transmit the quality information to the base station using the uplink quality control channel. The base station performs transmission control of data for the mobile station using the quality information. The mobile station is set to perform control of starting and stopping transmission of the quality information so that the quality information is transmitted only as required. Therefore, power consumption in the mobile station can be reduced, interference wave power in the uplink can be reduced, and capacity of the uplink can be increased.

摘要： The invention provides a sampling frequency conversion apparatus which converts a sampling frequency to another frequency using another oscillator employed in the system as the source oscillator. A fractional frequency divider divides an output of the source oscillator by a non-integer. By using outputs of the source oscillator and the divider individually as sampling clocks, an input signal is first sampled by a first sampling circuit and then an output of the first sampling circuit is sampled again by a second sampling circuit to convert the sampling frequency. The fractional frequency divider divides the clock signal of a higher one of the frequencies to produce the clock signal of a lower one of the frequencies, and the dividing ratio of the fractional frequency divider for the production of the clock signal is varied periodically to effect division of a frequency ratio having a fractional value when averaged over a time period.

摘要： In a combining circuit comprising first and second frequency converting sections (20a, 20b) for frequency converting first and second received signals from two independent antennas (10a, 10b) under the control of a control circuit (30) into first and second frequency-converted signals, first and second preliminary amplifying sections (60a, 60b) preliminarily amplify the first and the second frequency-converted signals under the control of the control circuit (30) to produce first and second preliminary amplified signals having first and second output levels, respectively. The first and the second preliminary amplified signals have first and second noise power levels, respectively, which are equal to each other. First and second main amplifying sections (40a, 40b) mainly amplify the first and the second preliminary amplified signals by first and second amplification degrees in proportional to the first and the second output levels, respectively. The first and the second main amplifying sections produce first and second main amplified signals having first and second phases, respectively. A signal combining section (50) combines the first main amplified signal with the second main amplified signal with the first phase shifted into the second phase. The signal combining section produce a combined signal.

摘要： In order to initially point a directional antenna mounted on a mobile unit to a stationary satellite, the antenna is rotated one revolution in azimuth. While the antenna rotates, the maximum receive signal strength is detected together with the angular position of the antenna at which the maximum strength has been ascertained. Subsequently, the antenna is rotated to the angular position which has been determined in the preceding operation. If the angular position is determined correct (viz., the mobile unit is detected to be synchronized with the satellite), then the initial antenna beam orientation is terminated.
