    摘要: A UE is described that includes a higher layer processor configured to receive a dedicated RRC configuration message which configures a License Assisted Access (LAA) cell. The UE also includes a PDCCH receiver configured to receive a first PDCCH and a second PDCCH. The first PDCCH is a PDCCH with CRC scrambled by CC-RNTI, and with a DCI format which contains a subframe configuration field. The second PDCCH is a PDCCH with DCI formats for scheduling physical uplink shared channel(s) (PUSCH(s)) on the LAA cell. If the first PDCCH is detected in subframe n, and the first PDCCH is not detected in subframe n−1, and if the number of occupied OFDM symbols for the subframe n indicated by the subframe configuration field in the subframe n is less than 14, the UE is not required to receive any other physical channels in subframe n except for the second PDCCH.

    摘要: A user equipment (UE) is described. The UE receives, from a base station apparatus, a radio resource control message including first information used for configuring a number of repetitions for transmission of a transport block. The UE also receives, from the base station apparatus, a radio resource control message including second information used for configuring a pattern of redundancy version for the repetitions for the transmission of the transport block. The pattern of the redundancy version is any one of a first pattern and a second pattern. The UE also performs, based on the first information and the second information, to the base station apparatus, the repetition for the transmission of the transport block. The same redundancy version used for the repetitions for the transmission for the transport block is a redundancy version “zero.”

    摘要: A user equipment (UE) is described that includes receiving circuitry configured to receive, from a base station apparatus, a radio resource control message including first information used for configuring a periodicity for an uplink data transmission, the receiving circuitry configured to receive on a physical downlink control channel, from the base station apparatus, second information used for indicating an activation for the uplink data transmission. Transmitting circuitry is configured to transmit, to the base station apparatus, confirmation information Medium Access Control (MAC) Control Element (CE) for the second information, the transmitting circuitry configured to perform on a physical uplink shared channel, to the base station apparatus, the uplink data transmission based on the first information and the second information. The receiving circuitry is also configured to receive on the physical downlink control channel, from the base station apparatus, third information used for indicating a deactivation for the uplink data transmission.

    摘要: A UE is described. The UE may include a higher layer processor configured to acquire a common dedicated radio resource control (RRC) configuration message and one or more dedicated RRC configuration messages. The common RRC message may include first information for indicating a slot format. The one or more dedicated RRC configuration messages including second information for configuring a semi-static downlink transmission and third information for configuring a semi-static uplink transmission. The UE may also include receiving circuitry configured to receive the semi-static downlink transmission. The UE may further include transmitting circuitry configured to transmit the semi-static uplink transmission. If the semi-static downlink reception and the semi-static uplink transmission are configured for a same set of symbol(s), the slot format indicates the set of symbol(s) as either downlink or uplink but not as flexible.
