    摘要: There is provided a base station control apparatus and a base station control method in which a frame is segmented in a situation in which interference may occur. A BS controller divides and controls a base station into three sectors and controls communications with terminal stations (TSs). A control unit determines whether or not the TS is in at least any of a state in which the TS is interfered within a certain sector by any other sector and a state in which the TS is located in a boundary between a plurality of sectors, and segments a communication frame for a TS which is determined as being in at least any of a state in which the TS is interfered within a certain sector by any other sector and a state in which the TS is located in a boundary between a plurality of sectors.

    摘要: A logical memory construction-processing section reads several kinds of physical memories and registers prepared in advance as libraries, generates candidates for each logical memory, by combining only the physical memories or only the registers, or both the physical memories and the registers, with each other, so as to construct the logical memory that satisfies a logical condition defining a memory space, and selects highest priority candidates for the logical memories from the candidates according to priorities. An optimum construction extraction-processing section extracts optimum logical memories satisfying the respective logical conditions from the highest priority candidates such that the limit numbers of usable physical memories and usable registers are satisfied. A circuit description-processing section executes circuit description by using the physical memories and the registers that construct each of the extracted optimum logical memories, to thereby generate a circuit description file.

    摘要: A wireless LAN terminal (AP) transmits a data frame to a counter wireless LAN terminal (STA-j), and receives an ACK frame from STA-j. AP measures a response time from the transmission of the data frame to reception of the ACK frame, and measures a transmission interval time from the previous transmission of the data frame to STA-j to the current transmission. AP includes a memory to store a predetermined set transmission interval time and a set response time for said terminal station. AP re-transmits the data frame when the transmission interval time does not exceed the set transmission interval time and the response time exceeds the set response time, and stores the response time in said memory as the set response time, when the transmission interval time exceeds the set transmission interval time.

    摘要: In a wireless LAN communication system in which the data transmission rate is asymmetric between an upstream channel and a downstream channel, a wireless band is effectively used. The transmission rate of an ACK (reception acknowledgement signal) is variably controlled between an AP (Access Point) and an STA (mobile terminal station), based on the number of retransmissions of a user data frame. Specifically, control is performed as follows. The number of retransmitted frames is counted, and if the value is greater than a predetermined value M, which means that the transmission quality of an ACK is poor, the ACK transmission rate is brought one level down. The number of successive successful frames is counted, and if the value is greater than a predetermined value N, which means that the transmission quality is good, the transmission rate is brought one level up. By this, although conventionally the ACK transmission rate is determined depending on the reception rate of a data frame, the ACK transmission rate is independently determined. Thus, the fast data transmission rate of a downstream channel does not depend on the ACK transmission rate and accordingly a limited wireless communication band is effectively used.
