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 controller configured to select, from a first method and a second method, one method for determination of a size of a transport block to be transmitted on a PUSCH, based on whether scaling is applied to the transport block, and a transmitter configured to transmit the PUSCH are included. In the first method, the size is determined based on NRE=min(X1, NaRE)·nPRB. In the second method, the size is determined based on NRE=min(X1, NaRE)·nPRB·?. The ? is provided by an RRC parameter. In a case that UCI is multiplexed on the PUSCH, the number of coded modulation symbols for the UCI is based on which method is selected as the one method from the first method and the second method.
Abstract: A terminal device for performing communication method, the terminal device comprising a receiver for receiving a PDCCH having a first DCI format; and a transmitter for transmitting a PUCCH including UCI, and a PUSCH.

Abstract: A receiver receives one or multiple first DCI formats, one or multiple second DCI formats, and a third DCI format. The third DCI format does not include a PDSCH group indication field. A PDSCH scheduled by the third DCI format is included in a first PDSCH group. A transmitter transmits a first HARQ-ACK codebook for the first PDSCH group, and/or a second HARQ-ACK codebook for the second PDSCH group. The third DCI format schedules a PDSCH. In a case that the third DCI format is detected, the transmitter transmits an HARQ-ACK bit corresponding to the PDSCH scheduled by the third DCI format.
Abstract: 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.
Abstract: Terminal device attempts to initiate a COT-u at the beginning of an FFP-u. In a case that the starting of the FFP-u collides with an IP-g, a PUSCH transmission overlapping with a period after the sensing slot and before the end of the IP-g is not scheduled. In a case that the starting of the FFP-u does not collide with the IP-g, the PUSCH transmission is scheduled and transmitted.
Abstract: A method for a base station which communicates with a user equipment (UE) is described. The method may comprise sending first radio resource control (RRC) configuration information. The first RRC configuration information may indicate code block group (CBG) transmission for a Physical Downlink Shared Channel (PDSCH). The method may also comprise sending second RRC configuration information. The second RRC configuration information may indicate Nmax which is a maximum CBGs per transport block. The method may further comprise, after a channel access procedure, transmitting, to the UE, a PDSCH containing a transport block with N CBG(s). N is an integer. The method may further comprise receiving, from the UE, a HARQ-ACK feedback including Nmax HARQ-ACK information bits for the transport block of the PDSCH. If N is smaller than Nmax, the HARQ-ACK information bit(s) for last Nmax-N CBG(s) may be set to NACK.
Abstract: An apparatus includes a coder configured to generate a first coded bit sequence by error correction coding of a bit sequence of uplink control information, a rate matcher configured to generate a second coded bit sequence by applying a prescribed amount Cs of cyclic shift to the first coded bit sequence for an s-th uplink channel instance of S uplink channel instances, and a transmitter configured to transmit the second coded bit sequence by using the s-th uplink channel instance. The prescribed amount Cs is determined based on at least some or all of a prescribed amount Cs?1 for an (s?1)-th uplink channel instance, the number of OFDM symbols included in the (s?1)-th uplink channel instance, and the number Nblockbit of coded bits mapped per OFDM symbol.
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 includes: a receiver configured to receive an SS/PBCH block in an SS/PBCH block candidate; and a transmitter configured to transmit one random access preamble selected in a PRACH occasion. The terminal apparatus determines the PRACH occasion, based on a relationship between qSSB and the PRACH occasion. The qSSB is given by one of a remainder obtained by dividing tSSB by QSSB or a remainder obtained by dividing dSSB by QSSB. The tSSB is a timing index of the SS/PBCH block candidate. The dSSB indicates an index of a DMRS for a PBCH in the SS/PBCH block. The QSSB indicates a number included in an MIB in the PBCH.
Abstract: Terminal device initiates a COT-u at the beginning of an FFP-u after the channel is sensed to be idle and transmit an uplink transmission burst within the COT-u. In a case that the COT-u overlaps with a sensing slot for initiating an FFP-g with the one or more SS/PBCH blocks, the COT-u is terminated before the sensing slot. In a case that the COT-u does not overlap with the sensing slot, the COT-u is terminated after the sensing slot.
Abstract: Terminal device initiates a COT-u at the beginning of an FFP-u after the channel is sensed to be idle. In a case that the maximum COT overlaps with an IP-g and the beginning of the IP-g is before the beginning of the IP-u, the uplink transmission is paused before or at the beginning of the IP-g and the uplink transmission is resumed after the channel is sensed to be idle.
Abstract: A terminal apparatus receives a PDCCH and receive a PDSCH scheduled by the PDCCH, and transmits (reports), via a PUCCH or a PUSCH, HARQ-ACK information corresponding to the PDSCH. Based at least on the PDCCH, a PDSCH group ID and a toggle bit corresponding to the PDSCH group ID are indicated. In a case that the toggle bit is toggled, HARQ-ACK information being already reported (the HARQ-ACK information other than HARQ-ACK information not being reported yet) is deleted from an HARQ-ACK codebook corresponding to the PDSCH group ID. The HARQ-ACK information corresponding to the PDSCH scheduled by the PDCCH is included in the HARQ-ACK codebook.
Abstract: A user equipment (UE) is described. The UE may comprise receiving circuitry configured to receive a downlink control information (DCI) format including an information field. The information field may indicate a combination of a channel access type, a cyclic prefix (CP) extension index and a channel access priority class (CAPC). The UE may also comprise transmitting circuitry configured to transmit a sounding reference signal (SRS) and a physical uplink shared channel (PUSCH). The SRS and the PUSCH may be based on the DCI format. There may be a gap between the SRS and the PUSCH. The gap may be longer than 16 microseconds. If the SRS is transmitted earlier than the PUSCH, the channel access type and the CP extension index corresponding to the indicated combination may apply to the SRS, a predetermined channel access type and a predetermined CP extension length may apply to the PUSCH, a predetermined CAPC may apply to the SRS, and the CAPC corresponding to the indicated combination may apply to the PUSCH.
