Abstract: A method for selecting one or more secondary cells, SCells for supporting communication with a user equipment, UE, by carrier aggregation, CA. The one or more SCells is/are selected from a set of SCell candidates available for an access node. The method includes estimating a probability that the UE connected to a primary cell, PCell, of the access node is in coverage of an SCell in the set of candidates, predicting available resources for the SCell, calculating a CA value for the SCell based on the estimated probability, an estimated spectral efficiency and the predicted available resources, and calculating a CA value for each SCell of the set of SCell candidates, ranking the SCells of the set of SCell candidates based on their calculated CA values, and selecting one or more SCells for providing CA with the UE based on the ranking.

Abstract: A method and apparatus are disclosed for non-collocated SCell selection for NR CA. In one embodiment, a network node is configured to estimate a first throughput for the WD at a first candidate secondary cell, the estimated first throughput being based on a measured inter-network node delay between the network node and a first network node supporting the first candidate secondary cell, the network node supporting a primary cell; and determine whether to select the first candidate secondary cell for the WD based on the first estimated throughput. In another embodiment, a network node is configured to determine an average amount of time resources associated with a Hybrid Automatic Repeat reQuest, HARQ, process exhaustion experienced by WDs connected to the first candidate secondary cell and primary cells with an inter-network node delay, d; and report the average amount.

Abstract: A method for user equipment, UE, configuration determination for a UE connected in a radio communication network is presented. The method is performed in a base station, BS, and comprises determining a minimum candidate user equipment configuration, CUEC, wherein the CUEC comprises a special cell, SpCell, the SpCell providing connection with the UE, validating the determined minimum CUEC against capabilities of the UE, selecting a successfully validated determined minimum CUEC as a current CUEC, generating a next CUEC and comparing the generated next CUEC with the current CUEC, validating the next CUEC against the capabilities of the UE when the next CUEC has a higher weight than the current CUEC, selecting a successfully validated next CUEC as the current CUEC, and configuring the UE in accordance with the current CUEC. A BS, a distributed unit, a computer program and a computer program product for UE configuration determination are also presented.

Abstract: The invention relates to methods and devices for enabling a connection of a wireless communication device released by a source radio base station to be resumed by a target radio base station. In a first aspect, a method of a source radio base station of enabling a connection of a wireless communication device released by the source radio base station to be resumed by a target radio base station is provided. The method comprises acquiring an indication that a connection established with the wireless communication device is to be released, identifying a target base station with which the connection to be released can be resumed for the wireless communication device, and transmitting, to the identified target base station, information required to resume the connection to be released by the source base station for the wireless communication device.

Abstract: An antenna system (150) comprises a Centralized Processing Unit (160); at least two antenna units (200) connected to the CPU (160) by cables. Each antenna unit (200) comprises at least one connector; one or more antenna elements (220) and one or more 5 Antenna Processing Units (230) connected to the one or more antenna elements (200). The one or more antenna processing units (230) are connected to a data bus connected to the at least one connector.

Abstract: A first radio access network, RAN, node in a communication network can determine whether to provide dual connectivity to a user equipment, UE, in the communication network based on an UL quality. The first RAN node can receive data indicating characteristics of an uplink, UL, channel of one or more UL channels for a second RAN node in the communication network. The first RAN node can estimate an UL quality of the UL channel based on the data. The first RAN node can determine based on the UL quality, whether to provide dual connectivity to the UE in the communication network by adding the second RAN node as a secondary node serving the UE.

Abstract: A radio network node receives a message that includes a New Radio, NR, neighbour information Element, IE. The NR neighbour information IE indicates that an NR cell neighbouring a served cell can provide dual connectivity together with the served cell. The radio network node may perform traffic steering based on the NR neighbour information IE. The radio network node may for example steer wireless devices capable of dual connectivity to the served cell and/or steer wireless devices not capable of dual connectivity to a different cell.
