摘要： In a transmission power control method, a base station apparatus and a communication terminal, transmission between the transmission side and the reception side can be preformed with an optimum transmission power. In the transmission power control method in which at the transmission side, a control signal for controlling the transmission power is transmitted, while at the reception side, the transmission power is controlled based on the received control signal, with the power value of the transmission power having reached the limit value of a power control range, if the instructions of the received control signal are to control the power value in the direction of allowing it to exceed the power control range, the number of receptions of the control signal is counted, and if the instructions of the control signal received thereafter are to control the power value in the direction of not allowing it to exceed the power control range, the count value of the number of receptions is decreased, and the power value is not controlled in the direction of not allowing it to exceed the power control range until the count value reaches a predetermined value.

摘要： The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.

摘要： A communication apparatus capable of reducing the amount of communication with other communication apparatuses is provided, wherein a content signal of a popular program is broadcasted in advance from a broadcast base station to terminals and stored in a memory of each. In a terminal, when a content signal specified by a play instruction signal is stored in the memory, the content signal is read from the memory. On the other hand, when it is not stored in the memory, the terminal requests the specified content signal from the cellular base station via a cellular network and receives the specified content signal.

摘要： The present invention relates to a communication method, and the invention enables it to avoid in advance mistaken restoration of a signal series which is sent in another communication even when the same channel is used in the other communication. An orthogonal matrix which is different for each communication is multiplied with the signal series and sent, and the signal series before orthogonal conversion is restored by multiplying the inverse matrix of the orthogonal conversion which is used on the sending side of the communication partner with the received signal series so that the other communication is performed by using the same channel. Even when the other communication is received, the signal series which is sent in the other communication is not restored even by multiplying the inverse matrix because the orthogonal matrix which is used in the orthogonal conversion is different from the other communication.

摘要： A received symbol sequence is very accurately restored in a highly efficient manner with a simple configuration, wherein, respective bits of an information bit sequence are inputted to a cyclic register composed of the same number of registers as the number of bits of the information bit sequence. Signals read from the cyclic register are processed to generate a plurality of symbols. The processing is repeated each time the respective bits of the information bit sequences are shifted to the next registers, until the respective bits shift all over the registers for one cycle. All symbols generated by the process are transmitted as a symbol sequence. Symbols of a received symbol sequence are respectively inputted to a first register group composed of the same number of registers as the number of symbols of the symbol sequence. Respective symbols in each of a plurality of assumed symbol sequences, prepared in accordance with the number of bits of the information bit sequence are inputted to a second register group composed of the same number of registers as the number of registers in the first register group. Respective output signals read from the respective registers in the first and second register groups are processed to calculate correlation values, and the information bit sequence is restored based on the assumed symbol sequence from which the largest correlation value is derived.
