UPLINK CHANNEL TRANSMITTING METHOD AND USER DEVICE, AND UPLINK CHANNEL RECEIVING METHOD AND BASE STATION

摘要

A first uplink channel and a first uplink reference signal for demodulating the first uplink channel may be transmitted within a first TTI having a predetermined time length. A second uplink channel and a second uplink reference signal for demodulating the second uplink channel may be transmitted within a second TTI having the predetermined time length. The first uplink reference signal may be transmitted in the last symbol among symbols in the first TTI, and the first uplink channel may be transmitted in the symbols remaining after excluding the last symbol of the first TTI from the symbols in the first TTI, and the second uplink reference signal may be transmitted in the first symbol among symbols in the second TTI symbols, and the second uplink channel may be transmitted in the symbols remaining after excluding the first symbol of the second TTI from the symbols in the second TTI. The last symbol of the first TTI and the first symbol of the second TTI may be the same symbol.
