Abstract: A pressure vessel includes a vessel body, a covering part, and a cylindrical mouthpiece. The vessel body includes a cylindrical open end portion on at least one end side of the vessel body. The covering part is made of a fiber reinforced resin and covers an outer surface of the vessel body. The mouthpiece is configured such that a plurality of mouthpiece bodies each having a projection on an inner surface of the mouthpiece body is connected to each other in a circumferential direction of the open end portion. The mouthpiece is attached to an outer peripheral surface of the open end portion by the projections biting into the covering part covering the outer peripheral surface of the open end portion. The mouthpiece bodies of the mouthpiece are connected to each other by fitting together fitting portions formed at end portions of the mouthpiece bodies in the circumferential direction.

Abstract: To perform communication efficiently. Provided are a receiver configured to receive a random access preamble and a transmitter configured to transmit one or multiple medium access control random access responses (MAC RARs) corresponding to the random access preamble. The transmitter sets, in a case that a MAC RAR of the one or multiple MAC RARs is transmitted in a new radio access technology (NR) cell, a timing advance command (TAC) field included in the MAC RAR to have a first size and an uplink (UL) grant to have a second size, and sets. in a case that a MAC RAR of the one or multiple MAC RARs is transmitted in an NR-unlicensed (NR-U) cell, a size of the TAC field included in the MAC RAR to be smaller than the first size and a size of the UL grant to be greater than the second size.

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: A communication method used for a terminal device is provided. The communication method comprises triggering transmission of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook; and when transmission of a second HARQ-ACK codebook is triggered before the first HARQ-ACK codebook has been transmitted, canceling the transmission of the first HARQ-ACK codebook; and transmitting the second HARQ-ACK codebook.

Abstract: The present invention is provided with: a radio resource control layer processing unit (16) configured to configure the number of PDCCH candidates configured in a dedicated control resource set, based on RRC signaling; a receiver (10) configured to monitor the multiple PDCCH candidates in the dedicated control resource set; and a decoding unit configured to decode the PDCCH candidates. a first number of the PDCCH candidates are monitored in the dedicated control resource set in a time period in which a common control resource set is not configured, a second number of the PDCCH candidates are monitored in the dedicated control resource set in a time period in which the common control resource set is configured, and a third number of the PDCCH candidates are monitored in the common control resource set. The sum of the second number and the third number is equal to the first number.

Abstract: A transport vehicle configured to run on electricity generated by a fuel cell includes: a body having a cargo space for freight; a chassis frame located below the body and supporting the body; and a tank unit including a plurality of tanks that stores fuel gas to be used for power generation by the fuel cell and a connecting portion connecting the tanks, the tank unit being located between the cargo space and the chassis frame.

Abstract: A high-pressure container unit includes: a box-shaped case mounted on a vehicle and configured to include a bottom portion, a ceiling portion, and a peripheral wall portion; a plurality of container main bodies arranged in an interior of the case and each having a cylindrical body portion; and a reinforcing member extending along an axial direction of the container main body, the reinforcing member being provided in at least one of a space surrounded by the container main bodies adjacent to each other and the bottom portion and, a space surrounded by the container main bodies adjacent to each other and the ceiling portion.

Abstract: A fuel tank has a tank body, a post, a first resistor, and a second resistor, a floating body, a detecting part, and a guiding part. The tank body stores fuel. The post is formed in a tubular shape, is formed with a flow port, and is joined to the bottom wall and the top wall. The first resistor and the second resistor are provided inside the post and extend in a height direction. The floating body is provided with a conductor, is formed with guided parts, and floats on the fuel inside the post. The detecting part energizes the first resistor, the conductor, and the second resistor to detect the position of the floating body in the height direction. The guiding part is provided on the post to guide the guided parts in the height direction.
