The present invention improves transmission efficiency in unlicensed bands. This base station comprises: a control circuit for determining a cyclic prefix (CP) length coordinated between a terminal and the base station; and a transmission circuit for transmitting control information regarding the determined CP length to the terminal.

Base station, terminal, and communication method

The objective of the present invention is to implement appropriate radio communication processing in accordance with required criteria. This terminal is provided with: a control circuit which determines a method for determining a priority level of a first channel and a second channel having mutually overlapping resource allocations in the time domain, on the basis of a parameter relating to control information indicating the allocations of the first channel and the second channel respectively; and a communication circuit for transmitting or receiving a signal to or from at least one of the first channel and the second channel, on the basis of the priority level.

Terminal and communication method

A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.

The present disclosure provides a transceiver device and a scheduling device, and communication methods for transceiver device and scheduling device. The transceiver device comprises a transceiver, which, in operation, transmits a scheduling request for scheduling data over a physical uplink control channel, PUCCH; and circuitry, which, in operation, initiates a monitoring sleeping timer after the transceiver transmitted the scheduling request, wherein the transceiver, in operation, does not monitor a physical downlink control channel, PDCCH, while the monitoring sleeping timer is running, and starts monitoring the PDCCH for resource allocation for the scheduling data when the monitoring sleeping timer has expired.

Transceiver device and scheduling device

A user equipment (UE) receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling; configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, each with a value indicating a PUSCH mapping type, a value K2 indicating a slot offsets, and a value SLIV indicating a start and length indicator value; and receives downlink control information (DCI) in form of medium access control (MAC) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The UE determines allocated resources for an initial PUSCH transmission and allocated resources for at least one repetition thereof, and performs a PUSCH transmission using the respectively determined allocated resources.
