  • Patent number: 10305630
    Abstract: An object is to suppress a decrease in communication quality and improve the communication quality even when interference is present in some of a frequency band in use in a case where a turbo coding scheme is combined with multicarrier communication using some of a frequency band shared with another system. A frequency selector (107) selects a band not used by another system, based on a measurement value of a reception level, then selects a subband for systematic-bit mapping from among subbands having a measurement value of the reception level lower than a threshold, and selects a subband for parity-bit mapping from among subbands other than the subband for systematic-bit mapping, for each subband (carrier frequency) of the selected band. A carrier-mapper (110) maps a systematic bit and parity bit to each subband based on the result of selection by the frequency selector (107).

  • Patent number: 9820174
    Abstract: The present invention aims to perform sensing of a frequency with high accuracy by securing a sufficient amount of time to measure a reception level of a guard time while avoiding a decrease in transmission rate as much as possible even when the distance between a terminal and a base station is short. To this end, a base station is disclosed which is configured to set a guard time based on the measured reception level of a UL signal during a period other than a period when it is time to measure an interference amount. Meanwhile, the base station sets a guard time so as to secure a predetermined length required for measurement of a reception level when it is time to measure the interference amount.
