摘要： A method performed by a first node includes obtaining a configuration for performing backhaul integrity protection and verification for backhaul adaptation protocol, BAP, data protocol data unit, PDU, packets transmitted and/or received over a backhaul link. The method includes computing a security token to be included in a BAP data PDU to be transmitted. The method includes adding the security token in the BAP data PDU. The method includes transmitting the BAP data PDU with the security token towards a second IAB node.

摘要： A method performed by a first donor distributed unit (DU) in an integrated access backhaul (IAB) network is provided. The method includes obtaining for each IAB node under the domain of each donor DU in the IAB network, a respective assigned IP address of the respective IAB node, receiving a rerouted packet, checking whether a source IP address of the rerouted packet matches an assigned IP address of an IAB node under the domain of the first donor DU, if the source IP address does not match an assigned IP address of an IAB node under the domain of the first donor DU, checking whether the source IP address of the rerouted packet matches an assigned IP address obtained by the donor DU, and if the source IP address matches an assigned IP address obtained the donor DU, forwarding the rerouted packet to an upper layer.

摘要： Methods are discussed to operate a wireless device in a wireless communication network. Shared channel occupancy time (COT) signaling is received from a Radio Access Network (RAN) node of the wireless communication network. An indication of a control resource is received from the RAN node. An indication of a shared COT switching point defining a switch from shared COT reception to shared COT transmission is received. Control signaling is transmitted to the RAN node using the control resource responsive to receiving the indication of the switching point and the indication of the control resource. Related methods are discussed to operate a Radio Access Network (RAN) node. Related wireless devices and RAN nodes are also discussed.

摘要： A radio device receives a first message from a further radio device. The first message indicates an intention of the further radio device to perform a device-to-device radio transmission on a set of radio resources. The radio device determines a status of the set of radio resources. In response to the first message, the radio device sends a second message comprising an indicator which indicates the determined status of the set of radio resources in terms of at least three levels.

摘要： According to certain embodiments, a method by a wireless device is provided for resource sensing. The method includes acquiring, from a network node, an indication of resources associated with a first resource pool. The first resource pool is for use in an exceptional communication with another device. A triggering event associated with signalling from the network node is identified. Based on the triggering event, a need for the exceptional communication with the other device is determined. At least one resource is selected from the first resource pool, and a message is transmitted using the at least one resource selected from the first resource pool.

摘要： A method in a node is disclosed. The method comprises generating a tag for an associated data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet. The method comprises signaling the tag from the first layer to another layer. The method comprises mapping, at the another layer, the associated data packet to a logical channel based on the one or more parameters indicated by the tag, and selecting one or more resources for transmission of the associated data packet based on the mapping of the associated data packet to the logical channel.

摘要： A method performed by a wireless device for reporting failure information in a self-organizing network, SON, is provided. The method includes receiving, from a source cell (“cell”) while being connected to the cell, a handover command to attempt a handover to a target cell, one or more bearers associated with the handover to the target cell being configured with a dual active protocol stack, DAPS. The method includes experiencing a failure while attempting the handover. The method includes storing first failure information associated with the failure. The method includes performing a DAPS fallback to the cell based at least in part on experiencing the failure. The method includes experiencing a radio link failure, RLF, while being connected to the cell. The method includes storing second failure information associated with experiencing the RLF. The method includes transmitting the first or second failure information towards the SON.
