FDD carrying capacity by exploiting existing TDD technology

摘要

A cellular communication system, comprising: a base transceiver station, BTS, (10), which transmits information in a frequency band descending deenlace, DL, (72) to one or more mobile devices (50) and receives information in one defrecuencia band uplink, UL, (74) the one or more mobile devices (50); division duplex frequency, FDD, (24) processor that alternately converts a first ysegundo duplex carriers time division, TDD, to a transmission signal in the band defrecuencia DL (72) with downlink transmissions according to an deconmutación predefined programming; and a memory (18) storing information related to programming of predefined switching, the identity of the TDD carrier, and the frequency bands DL and UL, where the BTS (10) transmits lastransmisiones downlink frequency band DL (72) using the first carrier TDDconvertido for a first portion of a transmission frame, and using the second carrier TDDconvertido for a second portion of the transmission frame, and in which the BTS receives transmisionesde uplink frequency band UL (74) with the second TDD carrier converted to labanda of uplink frequency to the first portion of the transmission frame, and elprimer TDD carrier that converts the frequency band uplink to the second porciónde transmission frame .
