    摘要： When a base station and a plurality of terminal stations communicate with each other by radio, power control information for controlling electric power of a signal transmitted to the base station is multiplexed at the base station and transmission energy is adjusted such that total transmission energy of the multiplexed power control information becomes substantially a predetermined value if the total transmission energy of the multiplexed power control information is lower than a predetermined value. Therefore, information such as power control information that should be individually instructed to respective terminal stations can satisfactorily be transmitted by a simple arrangement and a simple processing.

    摘要： Space-division multiple access is optimally realized while avoiding inter-network interference.Time usage information for transmission sequence units is exchanged among different networks or non-adjacent equipment, and on the basis of this information, a station that initiates a transmission sequence unit disposes the start time of its own transmission sequence unit in a time slot which is not being used by an adjacent network or adjacent equipment. As a result, multiple wireless networks or wireless communication devices are able to utilize a channel by time division even in cases where exclusive placement of frequency channels is difficult, and efficient space-division multiple access can be realized.

    摘要： A communication operation is suitably performed with application of Space Division Multiple Access in which wireless resources on a space axis are shared by a plurality of users.If a frequency width is narrowed to 20 MHz when the communication quality is high, the amount of transmittable data can be about half, and the frame length can be doubled. If the frame length is rather excessively long, switching is performed to a modulation scheme with the greater number of states to shorten the frame length. On the other hand, when the communication quality is low, switching is performed to a modulation scheme with the smaller number of states to lengthen the frame length. When the frame length is still insufficient, switching is performed to a narrow frequency width to lengthen the frame length.
