Base station apparatus, terminal apparatus, integrated circuit, and radio communication method

摘要

A terminal apparatus that communicates with a base station apparatus includes a configuration unit that sets a first configuration, a second configuration, and a third configuration. The configuration unit starts or restarts the timer when setting the third configuration, and the configuration unit clears/discards the third configuration when the timer expires. The first configuration is used to determine correspondence between a subframe in which PDCCH is arranged and a subframe in which PUSCH corresponding to the PDCCH is arranged, the second configuration is used to determine correspondence between a subframe in which PDSCH is arranged and a subframe in which a HARQ-ACK corresponding to the PDSCH is transmitted, and the third configuration is used to specify an uplink subframe in which uplink transmission is possible.

主权项

1. A terminal device comprising:
configuration circuitry configured to and/or programmed to configure a plurality of subframes to monitor a plurality of physical channels, each of the plurality of subframes including information indicating an uplink-downlink configuration; and receiving circuitry configured to and/or programmed to monitor, during a period, the information indicating the uplink-downlink configuration in each of the plurality of subframes until one information indicating an uplink-downlink configuration is detected during the period.
