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: In accordance with an example embodiment of the present invention, a method comprising: receiving, by a user equipment of a communication network, a request from a network node to use at least two beam configurations of multiple different beam configurations for the user equipment; measuring, by the user equipment, downlink received power on at least one reference signal using the at least two beam configurations; sending, by the user equipment on an uplink, information of at least two downlink received powers and at least one reference signal using the at least two beam configurations; receiving, by the user equipment, signaling from the network node comprising an indication of beam correspondence assessment from the network node; and adjusting, by the user equipment, uplink beam with reference to a downlink beam based on the received indication of beam correspondence assessment.

Abstract: To establish a multi-AP RRC connection with a user device UD the UD in the coverage area of multiple APs selects suitable ones as cluster set candidates and reports this list to a temporary serving AP the UD chooses. The multi-AP connection itself is setup by the cluster set manager CSM. The CSM collects information from each AP about control channels and load in order to choose which APs will be in the cluster, which will be the serving AP, and to setup the multi-AP connection with the UD. Multiple message exchanges are described for this purpose. Once the multi-AP connection is established, if the UD's connection with the serving AP fails the UD can handover to another AP of the cluster set without having to re-establish a new RRC connection. This is particularly useful for networks subject to severe shadowing effects such as mmWave 5G.
