The present specification provides a method for configuring transmission or reception timing of a wireless device, and a device using the same method. A method for performing uplink transmission by a wireless device in a wireless communication system may comprise a method in which, on the basis that a first serving cell and a second serving cell are included in a particular timing advance group (TAG), and first uplink transmission timing and second uplink transmission timing are different from each other, the uplink transmission is performed on the basis of uplink transmission timing coinciding with reference uplink transmission timing applied to a downlink timing reference cell among the first uplink transmission timing and the second uplink transmission timing.

Method for configuring transmission or reception timing of wireless device, and device using same method

The present specification provides a method for performing an integrated access and backhaul (IAB) operation by an IAB node in a wireless communication system, and an apparatus therefor, the method comprising: performing an initial access operation with another node; receiving uplink reception timing information of a child IAB node of the IAB node from the other node; and performing the IAB operation on the basis of the uplink reception timing information, wherein the uplink reception timing information is information related to whether a distributed unit (DU) operation of the child IAB node and a mobile terminal (MT) operation of the child IAB node can be simultaneously performed with respect to at least one time resource.

Method for IAB operation having multiple RX timings, and node using same

Proposed is a signal transmission method performed in a wireless communication system by an integrated access and backhaul (IAB) node, the method being characterized by comprising: receiving first information about a first timing and second information about a second timing; and transmitting a first signal and a second signal to a parent node of the IAB node, wherein the first signal is transmitted on a first resource, and the second signal is transmitted on a second resource. The first resource is a time resource to which the first timing is applied, and the second resource is a time resource to which the second timing is applied.

Communication method and device of IAB node having plurality of timings settherein

The present specification relates to a method for performing an integrated access and backhaul (IAB) operation performed by a node in a wireless communication system, and a device therefor, the method comprising: performing an initial access operation with another node; receiving timing alignment information from said another node; and performing the TAB operation on the basis of the timing alignment information, wherein the timing alignment information corresponds to information relating to a timing alignment case to be applied when the node performs the TAB operation.

Method for configuring timing alignment for IAB node, and node using same method

Provided are: a method for operating an integrated access and backhaul (IAB) node including a mobile terminal (MT) and a distributed unit (DU) in a wireless communication system; and a node using the method. Provided are: a method for operating another node communicating with the IAB node; and the other node using the method. The IAB node identifies a first resource allocated for the operation of the MT and a second resource allocated for the operation of the DU, the first resource and the second resource being resources in which overlap occurs in a time domain, determines a guard period in the first resource or the second resource, and performs either the operation of the MT or the operation of the DU in the guard period.

Method for operating IAB node in wireless communication system, and device using method

Provided are a method of operating an integrated access and backhaul (IAB) node including a mobile terminal (MT) and a distributed unit (DU) in a wireless communication system, and an apparatus using the method. The method identifies a specific resource supporting the simultaneous operation of the MT and the DU, and according to a type of a first signal that the MT intends to communicate in the specific resource and a type of a second signal that the DU intends to communicate in the specific resource, a multiplexing type to be applied to the specific resource is determined.

Operating method for IAB node in wireless communication system, and apparatus using same

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

Provided are an operation method performed by a first distributed unit (DU) of a first parent node communicating with a mobile terminal (MT) of an IAB node in a wireless communication system, and a device using the method. The first parent node acquires first configuration information about the first DU, acquires second configuration information about a second DU of a second parent node communicating with the MT, and restricts, on the basis of the first configuration information and the second configuration information, downlink transmission or uplink reception operations of the first DU if predetermined conditions are satisfied.

In the present specification, settings for a link direction and link availability of a time resource for a DU child link may be referred to as DU setting. The resource types from an IAB node DU perspective are UL, DL, and F, and the settings for availability may be classified into NA, hard resources, and soft resources, respectively. Specifically, the IAB node may receive resource setting information, wherein the resource setting information may include link direction information and availability information. The link direction information may indicate whether the type of a specific resource is UL, DL, or F, and the availability information may indicate whether a specific resource is a hard resource, an NA resource, or a soft resource. Considering the feature of sharing resources in a TDM scheme between a MT and a DU in the IAB node, the present specification proposes a feature to be had by a slot format setting for the IAB node.
