Abstract: An RF unit and a modem unit receive a packet signal, containing information regarding a frame construction, which is transmitted from a base station apparatus in a first period of a frame at least including first periods and second periods. An extraction unit identifies the second period in the frame, based on the received packet signal. A setting unit sets a waiting time period in the identified second period. A carrier sensing unit carries out carrier sensing over the waiting time period set by the setting unit. The modem unit and the RF unit broadcast the packet signal based on a result of the carrier sensing.

Abstract: Preceding filters receive the inputs of a plurality of received signals associated respectively with a plurality of antennas. Subsequent filters band-limit the plurality of inputted received signals, respectively. A first combining unit derives a weight vector for the plurality of band-limited received signals and performs array synthesis on the plurality of band-limited received signals, using the derived weight vector. The second combining unit performs array synthesis on the plurality of inputted received signal signals, using the derived weight vector. A demodulator demodulates the array-synthesis result.

Abstract: In response to a connection request from a terminal, a base station provides a signal indicating a reception operation adapted to a transmission operation of the base station to the terminal. Based on the indicating signal, the terminal selects and performs the optimum reception operation. The terminal also provides its own reception operation information in advance to the base station. Based on the reception operation information, the base station transmits a reception operation indication to the terminal. These processes are realized with software by DSP (12, 14) and the like.

Abstract: From received digital signals and a reference signal, a response vector computing unit computes a received response vector as a received response characteristic of the received signals against a transmission signal. The received response vector computed by the response vector computing unit is stored in a desired terminal response vector table. A virtual response vector for a virtual interception terminal apparatus is stored in a virtual intercepting terminal response vector table. A transmission weight vector computing unit computes a transmission weight vector necessary for weighting a transmission information signal from the received response vector and the virtual response vector, using a Wiener solution. A multiplication unit weights the transmission information signals with the respective transmission weight vectors so as to output transmission digital signals.
