Abstract: Terminal device attempts to initiate a COT-u after the channel is sensed to be idle and transmit a configured grant PUSCH. A start of a time domain resource of the configured grant PUSCH is aligned with the start of the FFP-u. In a case that the FFP-u does not overlap with an IP-g of an FFP-g, the COT-u is initiated and the configured grant PUSCH is transmitted.

Abstract: Terminal device attempts to transmit a PUSCH scheduled by a DCI format after the channel is sensed to be idle. When the start of the PUSCH is aligned with an FFP-u, in a case that the channel access mode is configured as semi-static, a ChannelAccess-CPext field in the DCI format indicates whether to initiate a COT or not.

Abstract: A user equipment (UE) is described. The UE may comprise higher layer processing circuitry configured to acquire first in radio resource control (RRC) information and second RRC information. The first RRC information configuring a semi-static channel access procedure. The second RRC information configuring a Channel State Information-Reference Signal (CSI-RS). The UE may also comprise receiving circuitry configured to receive the CSI-RS. If neither third RRC information for configuring a channel occupancy duration field nor fourth RRC information for configuring slot format indicator field is provided, a channel occupancy time for the semi-static channel access procedure is assumed to be a remaining channel occupancy duration indicated by the channel occupancy duration field.

Abstract: A terminal apparatus including a higher layer configured to configure a configuration related to a search space set and a configuration related to a PDCCH, and a receiver configured to monitor the PDCCH based on the search space set. In a case that one or multiple group indexes are allocated to the search space set and that neither monitoring of the PDCCH corresponding to the search space set with a group index of 0 among the one or multiple group indexes nor monitoring of the PDCCH corresponding to the search space set with a group index of 1 among the one or multiple group indexes is performed, the receiver initiates monitoring of the PDCCH corresponding to the search space set with a group index of 0 among the one or multiple group indexes.

Abstract: 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.

Abstract: Communication can be efficiently performed. In a case that a terminal apparatus is configured to monitor a first PDCCH candidate in a CSS and a second PDCCH candidate in a USS according to a DCI format accompanied with a C-RNTI in one non-interleaved CORESET having a period of one OFDM symbol, an aggregation level of the first PDCCH candidate is 8, an aggregation level of the second PDCCH candidate is 16, a lowest index of a CCE constituting the first PDCCH candidate is the same as a lowest index of a CCE constituting the second PDCCH candidate, a higher layer parameter PDCCH-DMRS-Scrambling-ID is not configured for the CORESET, and a size of the DCI format corresponding to the first PDCCH candidate is the same as a size of the DCI format corresponding to the second PDCCH candidate, it is considered that the DCI format is transmitted only in the first PDCCH candidate.
