FIELD: information technologies.
SUBSTANCE: methods and systems are described, which provide half-duplex communication in system of duplex communication with frequency division of channels (Frequency Division Duplex, FDD). Communication in FDD system may be divided into half-duplex interchanges, the terminal may accept reception within a single time period and may transfer within a different time period. Network of access in FDD system may use half-duplex circuit, to realise communication with access terminal, which is not capable of simultaneous receipt and transfer, using half-duplex interchange. Besides, network of access may use duplex circuit, to realise communication with access terminal, which is capable to receive and transfer simultaneously.
EFFECT: realisation of duplexer in system with high throughput capacity.
