Abstract: Provided are a method, a user equipment, a device and a recording medium in which: resource allocation information associated with a plurality of symbols is received; symbols which cannot be used for uplink transmission among the plurality of symbols are determined on the basis of the resource allocation information; and the uplink transmission is performed in at least one of the remaining symbols from the plurality of symbols excluding the symbols which cannot be used. The symbols which cannot be used comprise a symbol (DL symbol) in which a slot format is instructed as downlink (DL) and K non-DL symbols immediately after the DL symbol among the plurality of symbols. Each of the K non-DL symbols is a symbol in which a slot format is not instructed as DL, and K is an integer greater than 0.

Abstract: A user equipment generates an HARQ-ACK codebook comprising HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) based on multiple SPS configurations, and transmits the HARQ-ACK codebook. In the HARQ-ACK codebook, with respect to an SPS configuration index and a serving cell index, an HARQ-ACK bit for an SPS PDSCH in a slot of a lower slot index precedes an HARQ-ACK bit for an SPS PDSCH in a slot of a higher slot index, and with respect to each serving cell index, an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a lower SPS configuration index precedes an HARQ-ACK bit for an SPS PDSCH based on an SPS configuration having a higher SPS configuration index.

Abstract: According to an embodiment of the present disclosure, a user equipment (UE) may obtain fixed frame period (FFP)-related information, and perform clear channel assessment (CCA) for at least one FFP starting with a UE-initiated channel occupancy time (COT) for transmission of an uplink signal. The FFP-related information may include information about an FFP starting offset and information about an FFP duration or period, and the UE may identify a starting time of the FFP, based on the FFP starting offset having an orthogonal frequency division multiplexing (OFDM) symbol-level granularity.

Abstract: A method for transmitting an uplink physical channel in a wireless communication system and a device supporting the same are disclosed. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, transmission power related information via higher layer signaling, receiving a physical downlink control channel from the base station, and transmitting the uplink physical channel to the base station based on the physical downlink control channel, wherein the uplink physical channel includes a first uplink physical channel or a second uplink physical channel, wherein transmission powers for the first uplink physical channel and the second uplink physical channel are respectively calculated by different power related parameters determined based on the transmission power related information and the physical downlink control channel.

Abstract: An operating method of a node in a wireless communication system, and a device using the method are provided. The method transmits a link instability signal notifying a child node of the instability of a link if the link with a parent node is unstable, monitors, during a connection recovery time, whether a link recovery signal is received from the parent node, and transmits, to the child node, a handover trigger signal if the link recovery signal has not been received within the connection recovery time.
