    Abstract: Disclosed is method performed by a first RAN node (110) of an integrated access and backhaul, IAB, wireless communication network (100). The first RAN node (110) is connected to a core network (150) and is arranged for wireless communication with a second RAN node (120) and with a number of UEs (111, 112). Wireless communication resources are allocated for communication between the first RAN node (110) and the second RAN node (120). The method comprises assigning a first part of the resources for transmission of first data and a second part for transmission of second data, between the first RAN node (110) and the second RAN node (120), obtaining information of a vacant part of the resources, and triggering transmission of the first data and the second data using at least a fraction of the vacant part of the wireless communication resources for at least one of the first data and the second data.

    Abstract: A wireless device (14) is configured to receive an activation command (16) that commands the wireless device (14) to activate a serving cell (18B). The wireless device (14) is configured to activate the serving cell (18B) within a maximum delay (20) since receiving the activation command (16). The maximum delay (20) depends on whether there is at least one other serving cell (18A) already activated for the wireless device (14) in the same frequency band (24) as that in which the serving cell (18B) is to be activated.

    Abstract: Methods and apparatuses are disclosed for Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK, feedback. In one embodiment, a method implemented in a wireless device, WD, comprises receiving, from a network node, a first Downlink Control Information, DCI, scheduling a physical downlink shared channel, PDSCH; and receiving, from the network node, a second DCI, the second DCI comprising a HARQ-ACK feedback request trigger triggering a HARQ-ACK feedback for the PDSCH scheduled by the first DCI. In another embodiment, a method implemented in a network node comprises transmitting a first Downlink Control Information, DCI, scheduling the PDSCH; and transmitting a second DCI, the second DCI comprising a HARQ-ACK feedback request trigger triggering a HARQ-ACK feedback for the PDSCH scheduled by the first DCI.

    Abstract: A method for synchronization in a network node is disclosed. The method comprises determining an N-symbol slice of a received signal, the N-symbol slice corresponding to a sync point hypothesis, dividing the N-symbol slice into one or more segments, each of the one or more segments having the same symbol length, and determining one or more phase rotation operators for each of the one or more segments, the determined one or more phase rotation operators compensating for a phase rotation introduced by an initial frequency error. The method further comprises performing coherent correlation within each of the one or more segments using the determined one or more phase rotation operators, and performing differentially coherent correlation on each of the one or more segments.
