A terminal including: a control unit configured to compare a power reduction total value that is reduced from a maximum transmission power value determined based on a power class and that does not include a power reduction value for adjusting the power class with a predetermined value, and to calculate a lower limit value of a maximum transmission power by setting the power reduction value for adjusting the power class as 0 dB when the power reduction total value is greater than the predetermined value; and a transmission unit configured to perform uplink transmission using a maximum transmission power value equal to or greater than the lower limit value.

This application relates to a scheduling method, an apparatus, and a system. A first communications apparatus sends first signaling on a first resource, where the first signaling is used to indicate N communications apparatuses. The first communications apparatus sends second signaling on a second resource, where the second signaling is used to schedule the N communications apparatuses to send or receive first data, and the first resource has an association relationship with the second resource. In addition, the first resource has the association relationship with the second resource. In this case, a receive end of the first signaling and the second signaling may determine the second resource after determining the first resource, so that the second signaling is only detected on the second resource, and blind detection does not need to be performed on too many resources.

A method for listen-before-talk random access with adaptive energy detection threshold selection is executed by a device. Component units, such as code block groups (CBGs) in a transport block are determined to be retransmitted through a contention-based random access operation. A component unit based energy detection threshold (EDT) is selected. The EDT is associated with the component units determined to be retransmitted. The selected component unit based EDT is used to perform energy detection in an initial contention-based random access operation.

A method and a device of transmitting or receiving a downlink channel from multiple transmission and reception points in a wireless communication system is disclosed. A method of receiving a downlink signal by a terminal in a wireless communication system according to an embodiment of the present disclosure may include repeatedly receiving a downlink control channel including same downlink control information (DCI) in at least one transmission occasion (TO) from at least one transmission reception point (TRP); and based on the DCI including control information related to downlink signal reception, based on a time offset between a specific TO of the at least one TO and a receiving timing of a downlink signal related to the DCI being less than a predetermined threshold, receiving the downlink signal from a single TRP based on a default transmission configuration indicator (TCI) state and the default TCI state may be a TCI state related to a search space set or a control resource set (CORESET) having a lowest identifier in a latest slot that the terminal monitors.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives configuration information on monitoring capability of a physical downlink control channel (PDCCH) for each serving cell; and a control section that controls derivation of at least one of a first parameter and a second parameter, the first parameter being used for restriction at carrier aggregation on a number of a span-based PDCCH candidates monitoring, the second parameter being used for restriction at carrier aggregation on a number of a slot-based PDCCH candidates monitoring. According to one aspect of the present disclosure, appropriate PDCCH monitoring can be performed even when a span is used.

A terminal includes a control unit configured to perform LBT (Listen before talk) in a frequency band above a predetermined frequency, and a transmission unit configured to transmit a signal based on a result of the LBT, wherein the control unit performs the LBT with a mechanism different from LBT performed in a frequency band below the predetermined frequency.

Providing a building management system capable of preventing total communication traffic between a center apparatus and a communication terminal apparatus from exceeding a set threshold. The building management system includes: circuitry to calculate past communication traffic which is an accumulative value of traffic of communication received from a communication terminal apparatus; to calculate a remaining communication capacity by using information about a set first communication traffic threshold and information about the past communication traffic; and to create, if communication traffic required for transmission of first transmitted information to be transmitted to the communication terminal apparatus is larger than the remaining communication capacity, such second transmitted information that communication traffic required for transmission does not exceed the remaining communication capacity by dividing the first transmitted information, and to transmit the second transmitted information to the communication terminal apparatus.

A jamming satellite avoidance method changes an orbital altitude for each of orbital planes with different normal vectors in a mega-constellation satellite group composed of 100 or more satellites, so as to avoid a jamming satellite controlled by a ground device that is different from a device that controls the mega-constellation satellite group. The jamming satellite is an artificial satellite that includes a propulsion device and adopts a nominal orbital altitude and a nominal orbital inclination at which the mega-constellation satellite group flies, and maintains an average orbital altitude and an average orbital inclination while operating the propulsion device irregularly, and is controlled by the ground device that is different from the device that controls the mega-constellation satellite group.

A station apparatus according to the present invention includes a physical layer frame generator configured to selectively use a first coding scheme and a second coding scheme, a transmitter configured to transmit a frame including a control signal, and a higher layer processor configured to configure either the first coding scheme or the second coding scheme for information bits included in the frame, based on the control information, wherein the control signal includes first information indicating whether a reception method for changing a carrier sense level is allowed for a communication apparatus that receives the frame.

First information received by a first MLD on a first link is used to determine whether a BSS configuration of a second link is updated. In response to the BSS configuration of the second link not being updated, the first MLD directly transmits a data frame on the switched-to second link or the second link whose status is transited, and the data frame is not transmitted until a beacon frame is received and a latest parameter of the BSS configuration is obtained on the switched-to second link or the second link whose status is transited. A waiting time occurring before the data frame is transmitted is reduced.
