    摘要： A method for a user equipment (UE) which communicates with a base station is described. The method may comprise acquiring radio resource control (RRC) configuration information. The RRC configuration information may indicate a configuration of downlink control (DCI) format 2_0. The method may also comprise monitoring a physical downlink control channel (PDCCH) with the DCI format 2_0. The DCI format 2_0 may include a first information field. The first information field may indicate a remaining channel occupancy duration. The remaining channel occupancy duration may be expressed as the number of OFDM symbol(s) starting from a slot where the DCI format 2_0 is detected.

    摘要： A mobile station device includes an information acquisition unit that is configured to and/or programmed to acquire information, which specifies a system bandwidth and a carrier frequency of a second downlink carrier component different from a first downlink carrier component, transmitted using RRC signaling via a physical downlink shared channel within the first downlink carrier component and a communication unit that is configured to communicate with the base station device by aggregate use of both the first downlink carrier component and the second downlink carrier component, where the first downlink carrier component and the second downlink carrier component have different carrier frequencies and each of the first downlink carrier component and the second downlink carrier component has its own downlink system bandwidth.

    摘要： A base station which communicates with a user equipment (UE) is described. The RRC configuration information may indicate that a maximum number of codewords scheduled by DCI is two. The base station may comprise transmitting circuitry configured to, after a channel access procedure, transmit, to the UE, a PDSCH which contains only a first transport block. The base station may further comprise receiving circuitry configured to receive, from the UE, a HARQ-ACK feedback including at least a first HARQ-ACK information bit and a second HARQ-ACK information bit. The first HARQ-ACK information bit may correspond to the first transport block of the PDSCH. The second HARQ-ACK information bit may be set to NACK. A contention window for the channel access procedure may be adjusted using the HARQ-ACK feedback, wherein the second HARQ-ACK information bit may be ignored.

    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.”
