摘要： PROBLEM TO BE SOLVED: To use the band of a radio frame without waste when the radio frame of a fixed band performs bidirectional data communication between a base station and a plurality of subscriber stations. SOLUTION: The base station determine the number of time slots of slot request area TS14 variably in response to the number of the subscriber stations which grants a transmission right determined by the number of decision steps of the subscriber stations, and assigns the time slots which are not used as a slot request area TS14 to the data areas TS15, TS12 of the radio frame in the assigning step. If it does in this way, the transmission right of the time slots is not assigned to meaningless subscriber stations even by assigning, such as the subscriber stations in which a power source becomes in an off state, and the band of the radio frame can be utilized efficiently.

SOLUTION: In the P-MP system, a base station comprises: a low-speed polling means conducting polling using a significant signal for controlling subscriber station monitoring at a specified first cycle; a high-speed polling means conducting the polling using a nonsignificant signal at a second cycle higher than the first cycle while no polling using the significant signal is conducted: and an automatic gain control means applying the automatic gain control to the radio signal of a subscriber station by using a signal returned from the subscriber station at the polling by the high-speed polling means, and the subscriber station is provided with a means for identifying whether the received radio signal is the nonsignificant signal or the significant signal, returning the received radio signal as received to the base station when the received radio signal is the nonsignificant signal, and conducting control complying with the significant signal when the received radio signal is the significant signal. Thus, the system has the high-speed followup ability without causing an adverse effect on the monitoring control for the subscriber station, stably conducts the automatic gain control (AGC) even when no user traffic is available, and conducts efficient monitoring control for the subscriber station.

摘要： PROBLEM TO BE SOLVED: To prevent a mismatched frame from being generated when an overflow occurs in a receiving buffer and the part of a packet is defected in a radio system for recombining the frame based on sequential information at a reception side by dividing the frame into the packet, imparting the sequential information, and transmitting from a transmission side. SOLUTION: The rear half of the frame is discarded in which a first discarding unit 301 receiving a buffer full notification signal from the receiving buffer 64 is defected, and the front half of the frame is discarded in which a second discarding unit 302 is defected, is discarded. Thus, since the frame in which the partial packet is defected, the defected frames are not recombined. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To effectively use the band between a base station and a plurality of subscriber's stations even if an outgoing buffer overflow occurs at the subscriber's stations in a radio access system.
SOLUTION: When the buffer overflow of an outgoing reception buffer 61 in a subscriber's station 21 is detected, a flow control signal 74 in which an overflow is on is transmitted from a TDD/TDMA control circuit 52 to the base station 11. A slot allocation section 54 having received the flow control signal 74 stops the allocation of outgoing data to the target subscriber's station 21.

摘要： PROBLEM TO BE SOLVED: To provide a one-to-many radio communication system and a method thereof which can efficiently transmit the same signals to a plurality of subscriber stations and prevent deterioration in processing performance and an increase in delay in a base station.
SOLUTION: The system comprises the base station and the plurality of subscriber stations. The base station has the correspondence relation between information on destinations of data to be received from a network and numbers of the subscriber stations. When receiving data from the network, the base station correlates the received data to the subscriber station number corresponding to the destination information of the data and transmits it by a radio signal. Each of the subscriber stations has a subscriber station number unique to its own station and a subscriber station number unique to a multicast group to which its own station belongs to. Out of the radio signals transmitted from the base station, each of the subscriber stations receives data correlated to the subscriber station number unique to its own station and the subscriber station number unique to a multicast group to which its own station belongs to.
