In this network, OFDMA (Orthogonal Frequency Division Multiple Access) is used for the downlink radio communication, and SC-FDMA (Single Carrier-Frequency Division Multiple Access) is used for the uplink radio communication. The downlink radio communication performed by the small cell base station 20...
In the radio communication system1, the orthogonal frequency division multiple access (OFDMA) is applied to the downlink, and the single career frequency division multiple access (SC-FDMA) is applied to the uplink as the radio access mode. OFDMA is a multi-carrier transmission system which carri...
