Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method of increasing a nominal bandwidth occupancy rate using an unlicensed spectrum in wireless communication.,SOLUTION: A base station 105-a transmits a first orthogonal frequency division multiple access (OFDMA) communication signal to a wireless node 115-a at a licensed spectrum F2 and transmits a second OFDMA communication signal to a wireless node at an unlicensed spectrum F1 simultaneously with the transmission of the first OFDMA communication signal. A base station receives a first single carrier frequency division multiple access (SC-FDMA) communication signal from a wireless node at the licensed spectrum F2 and receives a second SD-FDMA communication signal at the unlicensed spectrum F1 simultaneously with the reception of the first SC-FDMA communication signal. The second SD-FDMA signal includes an interleaved signal with the interleaved signal increasing a nominal bandwidth occupancy rate at the unlicensed spectrum.,SELECTED DRAWING: Figure 2A,COPYRIGHT: (C)2020JPO&INPIT
