Various embodiments of the present disclosure relate to a next-generation wireless communication system for supporting high data transfer rates beyond the 4th generation (4G) wireless communication system. According to the various embodiments, a method of transmitting and receiving signals in a wireless communication system and apparatus for supporting the same may be provided.

Method and apparatus for transmitting/receiving wireless signal in wireless communication system

The method and apparatus for transmitting and receiving a signal in a wireless communication system disclosed herein operate based on a timeline configuration different from that in the prior art. Specifically, a timeline related to physical downlink control channel (PDCCH) reception, physical downlink shared channel (PDSCH) reception, and hybrid automatic repeat request acknowledgement (HARQ-ACK) transmission, a timeline related to PDCCH reception and physical uplink shared channel (PUSCH) transmission, and a timeline related to PDCCH reception, channel state information reference signal (CSI-RS) reception, channel state information (CSI) reporting may be modified for a subcarrier spacing (SCS) configuration of 5 or 6.

Method and device for transmitting/receiving signal in wireless communication system

According to an embodiment of the present disclosure, a user equipment (UE) may receive downlink control information (DCI) in a first fixed frame period (FFP) for frame based equipment (FBE) from a base station (BS), and perform a channel access procedure for a scheduled uplink (UL) transmission based on the DCI. In a first state in which it is indicated that the scheduled UL transmission is related to channel occupancy initiated by the BS, and the UE should perform channel sensing for the scheduled UL transmission, the UE may perform the channel access procedure for the scheduled UL transmission based on whether a resource for the scheduled UL transmission allocated by the DCI is confined within the first FFP in which the DCI is received.

Method and apparatus for transmitting and receiving signal in wireless communication system

A method and an apparatus for monitoring a signal in a wireless communication system, disclosed in the present disclosure, perform PDCCH monitoring based on a configuration regarding a search space set. The PDCCH monitoring may be performed in units of slot-groups and performed only in a certain number of consecutive slots in a period given by a periodicity and an offset. When a duration related parameter indicating the number of consecutive slots in which the search space may exist is absent in the configuration, the certain number is determined based on the size of a slot-group configured for the search space set.

Method for monitoring control channel, user equipment, device and storage medium, and method for transmitting control channel

Provided are a method for operating an IAB node connected to a plurality of parent nodes in a wireless communication system, and an apparatus using the method. The method comprises: monitoring all pieces of AI-DCI respectively received from the plurality of parent nodes; and determining whether or not a soft resource is available to a DU of the IAB node, in consideration of all results of the monitoring.

Method for operating IAB node connected to plurality of parent nodes in wireless communication system, and apparatus using method

A method of receiving a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, through a higher layer, (i) first information including a plurality of identifications (IDs) for a plurality of control resource sets (CORESETs) and (ii) second information related to resources of the plurality of CORESETs, determining an upper CORESET including the plurality of CORESETs based on the first information and the second information, and receiving the PDCCH through the upper CORESET. Each of the plurality of CORESETs is configured based on (i) a control channel element (CCE) supporting an aggregation level of 2n and (ii) N orthogonal frequency division multiplexing (OFDM) symbols, each of n and N being a positive integer and N being equal to or less than 3.

Method of transmitting and receiving downlink control channel and apparatus therefor

The present invention provides a method for transmitting and receiving a downlink signal between a terminal and a base station in a wireless communication system supporting an unlicensed band, and a device supporting the method. As a specific example, the present invention includes a method for: transmitting and receiving a physical downlink control channel (PDCCH) signal in an unlicensed band so that a base station and a terminal transmit and receive system information associated with a particular synchronization signal/physical broadcast channel (SS/PBCH) block; and, based on the PDCCH signal, transmitting and receiving a PDSCH signal including the system information.

Method for transmitting and receiving downlink signal between terminal and base station in wireless communication system supporting unlicensed band, and device supporting same

The present disclosure provides a method and an apparatus, wherein a terminal, for which a primary cell and a secondary cell are configured, performs a random access procedure, and a specific BWP on the secondary cell is activated on the basis that DCI received from a base station indicates non-dormancy.

BWP activation method for terminal

Disclosed are a method and device for transmitting and receiving a downlink channel on the basis of blind decoding in a wireless communication system. A method for a terminal to decode a downlink channel in a wireless communication system according to an embodiment of the present disclosure comprises: a step for transmitting capability information associated with one or more first monitoring schemes among a plurality of monitoring scheme candidates to a base station; a configuration information reception step for receiving configuration information about a second monitoring scheme among the plurality of monitoring scheme candidates from the base station, the complexity of the second monitoring scheme being no greater than that of the one or more first monitoring schemes; and a step for monitoring and decoding the downlink channel on the basis of the configuration information, wherein the plurality of monitoring scheme candidates may include a combined blind decoding (BD) scheme for the repeated transmission or split transmission of the downlink channel on a plurality of monitoring occasions (MO).

Blind decoding-based method and device for transmitting and receiving downlink channel in wireless communication system

The present invention relates to a wireless communication system and, more particularly, to a method and an apparatus for same, the method comprising the steps of: receiving one or more first data in a first slot group; receiving one or more second data in a second slot group, wherein the first slot group and the second slot group are different from each other; receiving downlink control information including first information relating to a slot group for which A/N feedback is required; and transmitting, through an uplink control channel, A/N information relating to a slot group, indicated by the first information, among the first slot group and the second slot group.

Method and apparatus for transmitting or receiving wireless signal in wireless communication system

According to the present specification, a fallback operation for when a terminal has not detected a DCI is newly proposed.

Method for operating terminal when DCI is not detected

Disclosed is a method of receiving a physical downlink control channel (PDCCH) through a search space (SS) set by a user equipment (UE) in a wireless communication system. The method includes transmitting first information related to the number of X slots and second information related to the number of at least one Y slot, and receiving a PDCCH through a UE-specific SS (USS) set within the at least one Y slot, based on the first information and the second information. The at least one Y slot is included in the X slots, and X and Y are positive integers.
