Claim of US Patent No. 10,342,016

1. A radio station comprising:at least one radio transceiver; and
at least one processor coupled to the at least one radio transceiver,
wherein the at least one processor is configured to allocate a first plurality of time-frequency resources and a second plurality of time-frequency resources to at least one radio terminal,
the first plurality of time-frequency resources are used to transmit or receive a first transport block in accordance with a first transmission time interval (TTI),
the first TTI is equal to a duration of one subframe,
a duration of the first plurality of time-frequency resources corresponds to the duration of one subframe,
the second plurality of time-frequency resources are used to transmit or receive a second transport block in accordance with a second TTI,
the second TTI is shorter than the duration of one subframe, and
a duration of the second plurality of time-frequency resources is shorter than the duration of one subframe,
wherein the at least one processor is configured to allocate, to the at least one radio terminal, a third plurality of time-frequency resources used to transmit uplink control information containing an allocation request for the first plurality of time-frequency resources,
wherein the at least one processor is configured to allocate, to the at least one radio terminal, a fourth plurality of time-frequency resources used to transmit uplink control information containing an allocation request for the second plurality of time-frequency resources,
wherein a duration of the third plurality of time-frequency resources corresponds to the duration of one subframe, and
wherein a duration of the fourth plurality of time-frequency resources is shorter than the duration of one subframe.
