| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In full duplex (FD), which improves spectrum efficiency and achieves flexible resource assignment between the uplink and downlink, the throughput cannot be improved to an ideal level due to self-interference (SI) from a transmitter when traffic loads are symmetric between the downlink and uplink. This paper investigates the effect of symbol repetition in every slot, which we recently proposed, on the signal-to-interference plus noise power ratio (SINR) at a demodulator input after SI suppression assuming the radio frame structure based on New Radio (NR) radio interface for FD. We first show that the maximum allowable input power of analog-to-digital converter doesn’t affect the SINR at a demodulator input. Then, we present the improvement in the SINR at a demodulator input and the resultant throughput when applying symbol repetition in every slot for some sets of subcarrier spacing and slot structures for FD with an asymmetric traffic distribution. | |
