It is herein disclosed a wireless device, first and second radio network nodes and methods performed therein for communication. A method performed by a first radio network node for determining a global identity of a second radio network node which is a neighbour of the first radio network node is provided. The method comprises one or more of: receiving length information which specifies a length of the global ID of the second radio network node, from a wireless device which is served by the first radio network node; and determining the global ID of the second radio network node based on the length information.

Wireless device, first and second radio network nodes, and methods performed therein for determining global ID of the second radio network node

The invention refers to a method performed by a control plane, CP, functional part () of a base station, the method comprising establishing a transport network layer, TNL, association with a network function (B) that supports a plurality of user plane, UP, functional parts of first base station; transmitting to the network function a request message () comprising information for selecting a first UP functional part among the plurality of UP functional parts; and receiving, in response to the request message, a response message () transmitted by the network function, wherein the response message comprises an identifier of the first UP functional part. The invention further refers to corresponding methods performed by the UP functional part, the network function, and to a corresponding base station.

Functional part selection in a disaggregated base station

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

Network architecture, methods, and devices for a wireless communications network

A network node () of a radio access network (RAN) of a wireless communication network () provides user plane security by establishing a secure tunnel between first and second tunnel endpoints () that will handle respective protocol layers of a same protocol stack for a Data Radio Bearer (DRB) () that is dedicated to user plane traffic and has yet to be established. Establishing the secure tunnel comprises exchanging an inner Internet Protocol (IP) address and an outer IP address of each of the endpoints () between the endpoints ().

User plane security in split RAN architectures

The invention relates to a method performed by a network function capable of supporting at least a user plane, UP, functional part of a base station (B), comprises establishing a transport network layer, TNL, association with a control plane, CP, functional part of the base station; receiving a request message () from the CP functional part of the base station (), wherein the request message comprises an identifier of the base station; creating a UP functional part of the base station using the identifier of the base station; and transmitting a response message () to the CP functional part of the base station, wherein the response message comprises an identifier of the created UP functional part of the base station; the invention further relates to a method performed by a CP functional part of a base station; and to corresponding network node adapted to perform above-described methods.

Automatic central unit user plane creation

Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration. The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

A method by a UE is provided to handle communication in a network, wherein the UE is capable of receiving a registration area configuration including area identifiers associated with different cells of different RATs. The UE receives, from a network node, a first mobile identifier and a second mobile identifier in a message during a transition of states of the UE, wherein the first mobile identifier is of a first length and the second mobile identifier is of a second length different than the first length. Furthermore, the UE uses the first mobile identifier to resume to a first network node of a first RAT in the registration area configuration of the UE, and the second mobile identifier to resume to a second network node of a second RAT in the registration area configuration of the UE.

Radio network node, UE and methods performed therein for handling communication in a wireless communication network

A method and radio access node for controlling beam transmission from a radio access node. The method identifies a number of user equipment (UEs) associated with a same beam set and groups the identified UEs into one or more corresponding groups. The method assigns a same discontinuous reception (DRX) phase to the UEs in each corresponding group, and coordinates transmission from the beam set to UEs in the one or more corresponding groups based on the assigned DRX phase.

Method and apparatus for controlling beam transmission to grouped user equipment (UES)

The present disclosure relates to a network node, a network control node, a wireless device and corresponding methods for optimized broadcasting of system information messages in a wireless network. The disclosure proposes a method, performed in a wireless device, of assessing system information perception capability in a wireless network that is arranged to broadcast system information on at least two frequency carriers. The method comprises receiving (S) broadcasted system information on the at least two frequency carriers. The method also comprises determining (S), using the received broadcasted system information, frequency carrier identity correlated information for each of the at least two frequency carriers. The method further comprises reporting (S) receipt of the broadcasted system information on the at least two frequency carriers, wherein the report includes the frequency carrier identity correlated information.

Optimized broadcasting of system information messages

A system and method is introduced for flexible user equipment ('UE') identification. In one embodiment, the method includes providing a first message from a user equipment () to a radio access node () to resume a passive user equipment context. The message includes a UE identifier () having a flag () indicating if the user equipment () is resuming connectivity to the radio access node () and a first local UE identifier () for the radio access node ().
