  • Publication number: 20210314896
    Abstract: If a propagation delay equal to or greater than a threshold value is detected in the uplink of a time-division duplex between a first wireless communication terminal and a first wireless base station, a suppression unit 52 performs control pertaining to resources in the time-division duplex of a first wireless communication terminal. Thereby, communication errors that occur in a second wireless communication terminal wirelessly connected to the second wireless base station that is different from the first wireless base station, to which the first wireless communication terminal is wirelessly connected, is suppressed by uplink communication performed by the first wireless communication terminal in accordance with the propagation delay. For example, this suppression process is a process pertaining to the assignment of resources a time-division duplex with respect to the first wireless communication terminal.

  • Patent number: 11109267
    Abstract: A base station apparatus receives an uplink shared channel and a reference signal, the uplink shared channel including uplink data, an identifier of a terminal apparatus that has transmitted the uplink data, a first CRC generated from the identifier bits, and a second CRC generated from the uplink data bits. In a case that an error is detected based on the first CRC, the base station apparatus transmits a first NACK by using a control signal associated with the reference signal sequence. In a case that an error is detected based on the second CRC, the base station apparatus transmits a second NACK by using a control signal associated with the identifier indicating the terminal apparatus.

  • Publication number: 20210250971
    Abstract: If a propagation delay equal to or greater than a threshold value has been detected in the uplink of the time-division duplex between a first wireless communication terminal and a first wireless base station, a suppression unit 52 controls communications of the first wireless communication terminal. In accordance with the propagation delay between a wireless communication terminal DR1 and a wireless base station BS1, wireless communication terminal DR1 transmits UL data ahead of time by the length of said propagation delay. This may cause communication errors to occur in wireless communication terminals DR2 and MT1 that are wirelessly connected to a wireless base station BS2, which is different from wireless base station BS1 to which wireless communication DR1 is wirelessly connected. Accordingly, suppression unit 52 suppresses said communication errors by controlling communications by wireless communication terminal DR1.

  • Patent number: 11044040
    Abstract: In a case that a CQI table applied to interpret a CSI report is changed from a first CQI table including modulation schemes up to 64QAM to a second CQI table including modulation schemes up to 256QAM, information on a CQI table selection indicating applicability of the second CQI table and a CSI subframe set indicating subframes for which a CQI table selected in the CQI table is used are transmitted. In a case that the CQI table applied to interpret the CSI report is changed from the second CQI table to a third CQI table including modulation schemes up to 1024QAM, only the information on the CQI table selection indicating applicability of the third CQI table is transmitted.

  • Patent number: 11026184
    Abstract: To improve throughput in a communication environment in which a large number of terminal apparatuses access, a receiver receives information indicating whether a radio resource allocated by a base station apparatus is a grant free access resource or a scheduled access resource, as well as transmission power control information in the scheduled access resource and transmission power control information in the grant free access resource; and a transmitter configured to transmit a transmission signal to the base station apparatus. In a case of communicating by using the scheduled access resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal. In a case of communicating by using the grant-free access resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.

  • Patent number: 11012111
    Abstract: In a case that a large number of terminal apparatuses that are accommodated by contention-based radio communication technologies share a frequency resource, the number of data signals of the terminal apparatus that are non-orthogonally multiplexed in the spatial domain increases. If terminal apparatuses, of which the number exceeds the number of receive antennas or the spreading factor transmit uplink data at the same time, it is tantamount to a presence of terminal apparatuses using the same spreading code, and inter-user interference becomes a problem.
