Abstract: Methods, apparatuses, and computer programs for timing enhancement for an integrated access and backhaul node are disclosed. A method includes receiving a control element that is used to determine a timing mode and/or associated timing information for an integrated access and backhaul node; determining the timing mode and/or the associated timing information for the integrated access and backhaul node, based on the control element; and applying the timing mode and/or the associated timing information for a subsequent uplink transmission for the integrated access and backhaul node.

Abstract: A method may include determining an uplink loss metric for an uplink communication path from a user equipment to a base station in a wireless network based at least on an uplink transmit beam for the user equipment and an uplink receive beam for the base station; determining a downlink loss metric for the downlink communication path from the base station to the user equipment based at least on a downlink transmit beam for the base station and a downlink receive beam for the user equipment; and determining, based on the uplink loss metric and the downlink loss metric, an uplink/downlink beam correspondence misalignment for the user equipment that indicates that the uplink transmit beam for the user equipment is misaligned with the downlink receive beam for the user equipment. For example, see FIGS. 5-6.

Abstract: A distributed unit, DU, of a radio access node configured to operate in a scenario where the DU is one of multiple DUs serving links to a multi-connected entity, acquires a first DU radio resource configuration for the DU, acquires a first link radio resource configuration corresponding to a first link of a multi-connectivity link of a multi-connected entity, wherein the first link is served by the DU, acquires a multiplexing configuration of the multi-connectivity link, and determines availability of at least one radio resource for the multi-connectivity link based on the first DU radio resource configuration, the first link radio resource configuration, and the multiplexing configuration.

Abstract: Systems, methods, apparatuses, and computer program products for GIS-NR beamforming for mmWave. For example, certain embodiments may provide for beam realignment, through which a serving network node may be able to re-position its beam towards a UE without the UE explicitly measuring and signalling to the network node the need for realignment. Instead of performing the traditional UE-based exhaustive beam search, the serving network node may proactively switch the beam in an attempt to track the UE movements. The serving network node may do this by corroborating information from two types of sources: 1) a set of neighbor mobile or fixed network nodes and 2) a geographic information system (GIS).

Abstract: A method including transmitting an uplink access request message by a user device (UD) for an access point (AP) in an access point cluster set of the UD; and monitoring a downlink control channel by the user device (UD) to determine, based at least partially upon the transmitted uplink access request message, if a subsequent uplink communication is to be transmitted by the user device (UD) to a serving access point and/or a stand-by access point of the access point cluster set.

Abstract: A method may include determining, by a user equipment, a beam alignment reference value and a beam alignment test value; and determining, by the user equipment, based on the beam alignment reference value and the beam alignment test value, that a user equipment receive beam used by the user equipment is not aligned with a transmit beam of the base station.
