FIELD: radio engineering, cellular radio communication systems. SUBSTANCE: technique of reception-transmission of multibeam signals in cellular radio communication system with code division of channels consists in formation on mobile station of L spatially-spaced channels for reception-transmission of signal and in search of beams of signal in each channel across interval of uncertainty by delay. Out of M detected beams there are selected N≤ beams highest by level of energy and their demodulation is conducted. Device for realization of technique has antenna, diplexer, analog receiver, search receiver, L data receivers. controlling processor, unit for integration of signals with decoder, unit of user's data, modulator of transmitter, power controller of transmitter, power amplifier of transmitter. There are formed L identical branches for reception- transmission of signal arranged in parallel. Antenna of each branch is spatially- oriented and has narrow radiation pattern. There are inserted two commutation units: one for selection of maximum information signals from data receivers, the other for connection of output signal of transmitter to channel over which signal of maximum level is received. EFFECT: provision for parallel search modes across interval of uncertainty y delay and for tracking in each of L spatially-spaced channels of signal reception-transmission. 6 cl, 9 dwg
