A method, system and network node are disclosed. According to one or more embodiments, a parent network node configured to communicate with a network node is provided. The parent network node is configured to, and/or includes a radio interface and/or includes processing circuitry configured to: enable a first timing configuration, wherein the first timing configuration enables downlink transmission timing for the network node to be aligned with the downlink transmission timing of the parent network node; and based on the first timing configuration, switch to a second timing configuration, wherein the second timing configuration enables uplink transmission timing of the network node to be aligned with the downlink transmission timing of the network node.

IAB Case-6 timing and adjustment

Systems and methods for selecting subcarriers to be used for sub-Physical Resource Block (PRB) transmission and, in some embodiments, for mapping Demodulation Reference Signals (DMRS) to resources on the selected subcarriers are disclosed. In some embodiments, a method of operation of a radio node for providing sub-PRB transmission comprises selecting two adjacent subcarriers from a set of three allocated subcarriers that are allocated for a sub-PRB transmission that uses Single Carrier Frequency Division Multiple Access (SC-FDMA) Pi/2 Binary Phase Shift Keying (BPSK) modulation using only two adjacent subcarriers out of the set of three allocated subcarriers with Discrete Fourier Transform (DFT) spread length of 2. In some embodiments, the selection is such that the selected adjacent subcarriers varies, e.g., from one cell to another. In doing so, interference is distributed.

Systems and methods for selecting subcarriers for sub-PRB transmissions

One embodiment provides a method performed by a wireless device. The method comprises: receiving, from a network node, a configuration message comprising an indication of preconfigured radio resources for uplink transmissions; obtaining a synchronization status of the wireless device with respect to the network node; and adapting use of the preconfigured radio resources based on the synchronization status of the wireless device with respect to the network node.

Methods, apparatus and computer-readable mediums relating to uplink transmissions

There is provided a method for determining and sharing a synchronization accuracy/error for a number of IAB nodes in a chain of IAB nodes communicatively coupled to each other. The method comprises: receiving from each IAB node in the chain of IAB nodes, information about a synchronization error for each IAB node; and reporting an accumulated synchronization error to the respective IAB nodes in the chain of IAB nodes, in response to receiving the information about the synchronization error for each IAB node.

Methods to monitor, configure, manage and signal synchronization for integrated access backhaul (IAB) links

Methods, nodes and computer program products control radio channel deployment when using un-licensed carriers in a wireless communication network and control mobility and/or load balancing target selection when using un-licensed carriers. When performed in an access node, unlicensed carrier intrinsic cell channel load is determined in a cell served by the access node based on one or more predetermined channel load indicators and neighbor cell channel load information is obtained, from one or more neighboring access nodes. The neighbor cell channel load information includes unlicensed carrier channel load in respective cells based on the one or more predetermined channel load indicators. At least one channel deployment operation is initiated based on an outcome of one or more comparative operations including the determined unlicensed carrier intrinsic cell channel load and/or the obtained neighbor cell channel load information.
