摘要： The present invention carries out transmission/reception of broadcast channels using only the last downlink slot of subframes using signals having a TDMA structure according to a CDMA/TDD system, and thus flexibly handles various services and avoids problems of interference in self-operated services in particular. The base station communication apparatus repeatedly transmits information contained in broadcast channels by the number of times corresponding to the time-sharing number and appropriately allots uplink and downlink slots, thus making the most of the features of uplink open-loop transmission power control and base station transmission diversity.

摘要： The base station apparatus compresses one-frame information of a broadcast channel to blocks of ½ of one frame or less and repeatedly sends this block in a one-frame time. The mobile station apparatus decodes the received signal in block units or added block units to carry out error detection. The mobile station apparatus receives and adds up the next block in the case that the error rate exceeds a threshold. The mobile station apparatus repeats this until the error rate falls below the threshold. When the error rate falls below the threshold, the mobile station apparatus stops reception of broadcast channel signals and uses the rest of time until a one-frame time elapses to monitor carrier information of a different mobile communication system for handover.

摘要： In a receiving side apparatus 150, reception quality of receive data is measured by a reception quality measurement section 157, receive data errors are detected by an error detection section 156, and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section 158. In a transmitting side apparatus 100, when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus 150 is detected from a reception quality signal by a scheduling section 110, and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.

摘要： A mobile radio apparatus includes a base station and a mobile station which communicate with each other by a hybrid code division multiple access scheme. The base station selects a hopping pattern in a frequency hopping method so as to completely avoid overlapping of a carrier for a forward link signal with a carrier for a reverse link signal at the same time, and transmits the forward link signal in a predetermined frequency band. The mobile station similarly transmits the reverse link signal. The mobile station has a multiplier for multiplying the forward link signal by a carrier at the same frequency as the carrier for the forward link signal to derive a received signal, a communication channel correlator for detecting a correlation of the received signal to separate a communication channel signal, a received power level detector circuit for detecting a received power level of the communication channel signal, and a transmission power level control signal for controlling a transmission power level of the reverse link signal, when transmitted to the base station, based on the received power level of the communication channel signal, using a carrier at the same frequency as the carrier for the forward link signal when the received power level of the communication channel signal is detected.

摘要： A base station transmits a first signal spread according to a direct spread scheme and having carrier frequencies hopped between two frequencies f1 and f2. In a mobile station, output signals of two carrier generators are changed over by a change-over switch. When the signal transmission frequency in the base station is f1, the mobile station receives the first signal having the frequency f1 and transmits a second signal having the frequency f2. When the signal transmission frequency in the base station is f2, the mobile station receives the first signal having the frequency f2 and transmits the second signal having the frequency f1. A received power level detector in the mobile station detects a power level of the first signal received during each hop (the duration of the same frequency), and, on the basis of the detected power level, a transmission power level control circuit controls the power level of the second signal to be transmitted during the next hop, that is, at the time of transmission of the second signal having the same carrier frequency as that of the first signal whose power level has been detected.

摘要： A base station transmits, in addition to a pilot channel, signals which are multiplexed with pilot symbols inserted in the respective signals in communication channels. As the transmission of the pilot channel as a reference signal for coherent detection is unnecessary with high power so as to attain high reliability, the pilot channel can be transmitted with low power by means of weight in comparison with the communication channel, so that interference with the communication channel of any other station is reduced. Moreover, accurate coherent detection can be made from the pilot symbol inserted in the communication channel on the mobile station side.
