    Abstract: A radio access node comprises one or more processors configured to determine a first reference timing of a first communication connection between the radio access node and a second, parent radio access node; determine a second reference timing of a second communication connection between the radio access node and a third, child radio access node; a memory storing the first and second reference timings; the one or more processors further configured to generate a request for the child radio access node to perform a timing advance adjustment based on the stored first and second reference timings, so that an uplink receive signal transmitted by the child radio access node arrives at the same time at the radio access node as a downlink receive signal transmitted by the parent radio access node arrives at the radio access node in case of frequency division multiplexed signals.

    Abstract: Disclosed are methods, systems, apparatus, and computer programs for communicating new link availability configurations for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a Radio Resource Control (RRC) message from an IAB node; determining, based on the RRC message, a new resource availability configuration for a backhaul resource associated with the IAB node; and in response to determining the new resource availability configuration, conditionally communicating with the IAB node over the backhaul resource according to the new resource availability configuration.

    Abstract: An apparatus configured to be employed in a gNodeB associated with a new radio (NR) system is disclosed. The apparatus comprises one or more processors configured to configure one or more sidelink sounding reference signals (SRS), for one or more user equipments (UEs) associated with the gNodeB, to be utilized by the one or more UEs for transmission or reception, or both, over sidelink. The one or more processors is further configured to generate one or more sidelink SRS configuration signals to be provided, respectively, to the one or more UEs, wherein each sidelink SRS configuration signal comprises sidelink SRS configuration information on the one or more sidelink SRS configured for a respective UE. The apparatus further comprises a radio frequency (RF) interface, configured to provide, to a radio frequency (RF) circuitry, the one or more sidelink SRS configuration signals, for subsequent transmission to the one or more UEs, respectively.

    Abstract: Disclosed are methods, systems, apparatus, and computer programs for determining in a new radio (NR) integrated access and backhaul (IAB) system a start symbol of available soft resources of an IAB node. In one aspect, a method includes determining, by a distributed unit (DU) of the IAB node and based on a configuration signal received from a central unit (CU) of an IAB donor, a configuration of available soft resources for a child link of the IAB node. The method further includes determining, based on the configuration of available soft resources, a start symbol of the available soft resources. The method also includes using the available soft resources for one or more child link transmissions starting from the start symbol.

    Abstract: Disclosed are methods, systems, apparatus, and computer programs for establishing a data path between an access node and a donor node of an integrated access and backhaul (IAB) network. In one aspect, a method includes selecting a subset of the plurality of nodes to establish the data path, where the subset of nodes includes the access node and one or more intermediate nodes that link the access node to the donor node, and where the one or more intermediate nodes include a final intermediate node that is coupled to the donor node via a donor-node backhaul bearer, establishing an access link bearer that couples a user equipment (UE) to the access node, establishing respective backhaul link bearers between the subset of nodes, and mapping a final one of the respective backhaul link bearers to the donor-node backhaul link bearer.

    Abstract: This disclosure describes methods, systems, and devices for efficient medium access control (MAC) control element (CE) signaling that controls uplink data duplication. In one example, a method involves generating a message including a MAC CE for indicating an activation or deactivation status of one or more radio link control (RLC) channels associated with packet data convergence protocol (PDCP) duplication. The method further involves encoding the message for transmission to a user equipment (UE).

    Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process a configuration transmission carrying a half-tone shifting indicator. The second circuitry may be operable to select one or more subcarrier frequencies for Uplink (UL) transmission based on the half-tone shifting indicator. The third circuitry may be operable to generate a UL transmission for the one or more subcarrier frequencies. The half-tone shifting indicator may have a first value indicating application of a half-subcarrier offset, and a second value indicating no application of the half-subcarrier offset.
