Abstract: A method by which a first device performs wireless communication and an apparatus supporting the method are provided. The method may comprise the steps of: acquiring information related to a resource block (RB) set in which a channel access procedure is performed in a shared spectrum; acquiring a threshold for adjusting a transmission parameter; performing channel sensing on the RB set; determining the transmission parameter on the basis of a result of the channel sensing for the RB set and the threshold; and performing sidelink (SL) communication with a second device on the basis of the transmission parameter.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may select a random access message type for establishing connectivity with a core network, the selecting between a first random access message type associated with a non-terrestrial radio access technology and a second random access message type associated with a terrestrial radio access technology. The UE may transmit, during or after a random access procedure to establish a connection with the core network, a random access message in accordance with the selected random access message type. The UE may communicate with the core network via the connection.

Abstract: Proposed is an operation method of a first device (100) in a wireless communication system. The method may comprise the steps of: determining the length of a channel sensing interval; selecting at least one resource on an unlicensed band; performing first channel sensing from a point of time that is before a start point of time of a first resource from among the at least one resource by as much as the channel sensing interval to the start point of time of the first resource; and performing SL transmission by using the first resource on the basis of a result of the first channel sensing being idle.

Abstract: Aspects of the present disclosure provide techniques for addressing scenarios where the minimum transmit power supported by a wireless node (e.g., an Integrated Access and Backhaul (IAB) node) is above a minimum value specified by a standard. In some cases, the node may signal information regarding its power configuration so a network entity of the may take it into account (e.g., when allocating or scheduling resources). The power configuration may include an indication of the minimum transmit power supported by the node and/or an indication of a guard band that may help the IAB control adjacent channel leakage.

Abstract: A method by which a first device performs wireless communication is provided. The method may comprise the steps of: acquiring a sidelink (SL) discontinuous reception (DRX) configuration; acquiring a channel occupancy time (COT) on the basis of type 1 listen before talk (LBT); receiving first sidelink control information (SCI) for scheduling of second SCI and a physical sidelink shared channel (PSSCH) via a physical sidelink control channel (PSCCH) within an active time; and receiving the second SCI and data via the PSSCH within the active time, wherein the SL DRX configuration may include at least one of an SL DRX onduration timer, an SL DRX inactivity timer, an SL DRX retransmission timer, and an SL DRX hybrid automatic repeat request (HARQ) round trip time (RTT) timer, at least one of a time at which the SL DRX onduration timer is running, a time at which the SL DRX inactivity timer is running, and a time at which the SL DRX retransmission timer is running may be included in the active time of the first device, and the COT may be included in the active time of the first device.

Abstract: The embodiments of the present disclosure belong to the technical field of communications. Disclosed are a sidelink communication method and apparatus. The sidelink communication method is applied to a terminal device, and comprises: determining whether a continuous LBT failure is triggered on a sidelink sending resource of a shared frequency; and when the continuous LBT failure is triggered, reporting a failure indication to a network device or determining a backup sidelink sending resource, so as to send a sidelink message. Therefore, a terminal device can send data in a timely manner when LBT fails, thus avoiding data loss and increasing the communication reliability.
