摘要： A decision is made as to whether a radio base station acting as an interference source is present in a macrocell or microcell, so that the interference from a mobile station transmitting high power can be presented in advance. The base station inserts its transmission power value of a forward broadcast channel into broadcast information. A newly installed base station C, receiving a forward frequency band, measures the received level of the broadcast channel, and captures the transmission power value. When the transmission power value is large, the threshold value is reduced (THRb), and when the transmission power value is small, the threshold value is increased (THRa). If the received level L is less than the threshold value, a decision is made that the channel is available.

摘要： A base station 422 of a second system performs communication using a frequency adjacent to a frequency employed by communication between a base station 412 and a mobile station 414 of a first system. When the mobile station 414 is close to the base station 422, the communication of the base station 422 undergoes interference by the leakage power of the mobile station 414. To avoid the interference, the transmission is halted of the mobile station 414 of the first system, which provides the interference by the leakage power.

摘要： A spreading and/or despreading mechanism in which the inphase component and a quadrature component of a signal are to be transmitted by using a short code and a long code. The long code has an inphase component and a quadrature component that are different from each other. The spreading and despreading operations carry out a complex-to-complex operation between a combination of the inphase component and the quadrature component of the signal and a combination of the inphase component and the quadrature component of the long code.

摘要： A CDMA mobile communication scheme capable of increasing a number of sectors while not increasing a number of perch channel spread codes and not jamming the control channel traffic, so as to obtain the capacity increase effect by the use of the sector configuration effectively. At the base station, a perch channel spread by an identical perch channel spread code assigned to the base station is transmitted from each one of at least two sectors of the base station. Then, upward signals from each mobile station are received at more than one reception sectors, the upward signals received at more than one reception sectors are despread by using an identical uplink spread code, and a maximal ratio combining of despread upward signals is carried out, in a case of carrying out a simultaneous reception at more than one reception sectors. Also, downward signals are spread by using an identical downlink spread code, and spread downward signals are transmitted from more than one transmission sectors to each mobile station, in a case of carrying out a simultaneous transmission from more than one transmission sectors.
