Abstract: A terminal apparatus includes a receiver and a transmitter. The receiver receives, from a base station, a downlink assignment index (DAI) that is transmitted by means of a downlink control information (DCI) format. The DAI indicates an accumulative number of a transmitted physical downlink shared channel (PDSCH) included in a group of PDSCHs. A range of the accumulative number of which the DAI is indicative is variably configured. The transmitter, in operation, transmits, to the base station, hybrid automatic repeat request acknowledgement (HARQ-ACK) information based on the DAI.

Abstract: An electron-emitting element includes an electric field applying portion comprising of a dielectric formed on a substrate, a first electrode formed on one surface of the electric field applying portion, a second electrode being formed on the surface of the electric filed applying portion, and a slit formed in cooperation with the first electrode.

Abstract: An electron emitter has an electric field receiving member formed on a substrate, a cathode electrode formed on one surface of the electric field receiving member, and an anode electrode formed on the one surface of the electric field receiving member, with a slit defined between the cathode electrode and the anode electrode. The electric field receiving member is made of a dielectric material. The electron emitter also has a modulation circuit for modulating a pulse signal applied between the cathode electrode and the anode electrode based on a control signal supplied from a controller such as a CPU to control at least an amount of emitted electrons.
