Abstract:
1. A communication system having a plurality of sectors, supporting a plurality of radio channels, and transmitting signals through the radio channels, each sector comprising: a generating unit that is structured to generate a downlink signal; a spreading unit that is structured to spread the generated downlink signal by using a long code, wherein the spreading unit sets a phase of the long code by using a phase offset different from that of other sectors; and a downlink transmitting unit that is structured to transmit the spread downlink signal at a frame transmission timing through a distinct radio channel, wherein the downlink transmitting unit sets the frame transmission timing by using a timing offset corresponding to the distinct radio channel and being different than the timing offset for at least one of the other of the plurality of radio channels; the communication system further having a mobile terminal that comprises an uplink transmitting unit that is structured to transmit an uplink signal to at least one sector of the plurality of sectors; wherein the uplink transmitting unit is structured to set a frame transmission timing of an uplink signal corresponding to the downlink signal transmitted by the downlink transmitting unit according to the timing offset of the downlink signal.
