摘要： In order to accomplish efficient communication of data between a base station and a plurality of mobile terminals, particular orthogonal codes are transmitted from the mobile stations to the base station as alert signals indicating the presence of data to be transmitted. The base station checks whether particular orthogonal codes are contained in the alert signals, and when the particular orthogonal codes are detected in the alert signals, information representing the detected orthogonal codes and the schedules for transmitting the data from the mobile terminals to the base station are transmitted from the base station to the mobile terminals as an alert response to the alert signals. When the information representing the orthogonal codes used for the alert signals are contained in the alert response transmitted from the base station to the mobile terminals, the data waiting to be transmitted is transmitted from the mobile terminals to the base station according the data transmission schedules in the alert response.

摘要： A method and apparatus for controlling the power of a signal transmitted between a base station and a mobile terminal which constitute a mobile communication system. At least one of the base station and the mobile terminal has functions to compare a predetermined reference value and a necessary transmission power obtained as a result of transmission power control in order to compensate for a signal intensity fluctuation occurring on a link between the base station and the mobile terminal, temporarily stopping the transmission if the necessary transmission power is larger than a predetermined permissible value, and transmit the signal if the necessary transmission power is equal to or smaller than the predetermined permissible value.

摘要： A code division multiple access (CDMA) mobile communication system with improvements to permit stable reception with a minimum of bit error. The system includes a base station and a mobile station for communicating with the base station. The mobile station includes an oscillator, a radio frequency demodulator for demodulating a radio frequency band signal received from the base station by use of a first signal from the oscillator, a radio frequency modulator for modulating a second signal to be transmitted by use of the first signal from the oscillator, and an antenna for receiving the radio frequency band signal transmitted from the base station, and for transmitting the modulated second signal to the base station. An oscillation frequency of the oscillator is controlled by use of a change of phase shift detected using the demodulated radio frequency band signal received from the base station.

摘要： The invention intends to solve a problem that an S/I ratio of a signal from a target base station deteriorates when there is a terminal near another base station. For this purpose, a signal replica of the signal from the nearby base station is generated and the replica is subtracted from a receiving signal. A signal of the target base station is detected from the resultant receiving signal. The signal from the nearby base station is deleted from the denominator of the S/I ratio, thereby increasing the S/I ratio.

摘要： In a P-MP fixed wireless access system using quasi-millimeter and millimeter wave bands, a relaying path is autonomously set up for subscriber stations without the need for additional provision of a repetition radio circuit using a costly MMIC. A subscriber station in the fixed wireless access system is provided with a repeating function for relaying signals between a different subscriber station and a base station, a buffer memory for temporarily storing signals to be communicated therebetween, and a table for registering information for identifying a relaying path between an own reference wireless station and a lower-level subscriber station for signal repetition. The base station is provided with a table in which, in order to perform signal communication with an arbitrary subscriber registered in the base station, routing information is registered for determining whether or not to set up a relaying path via a different subscriber station registered in the base station.
