The present disclosure relates to a method performed by a User Equipment (UE) for handling mobility information in a communications network. The UE predicts the mobility information. The UE reports the predicted mobility information to a first network node currently serving the UE in the communications network.

Methods, UE and first network node for handling mobility information in a communications network

A method of selecting a set of beams to be monitored by a User Equipment (UE) in a telecommunication network comprises the steps of receiving measurement data comprising measurements of qualities of beams observed by said UE, where said beams originate from at least one access node (AN) to the UE and from at least one other AN to the UE; retrieving at least one measurement data from a particular UE that matches the received measurement data, where the historical database comprises historical measurement data comprising measurements of qualities of beams observed by UE's in said telecommunication network over time; selecting a set of beams to be monitored by said UE based on the retrieved measurement data and based on subsequent measurement data of the particular UE over time in the historical database; and transmitting said selected set of beams to be monitored to said UE.

Method, base station and a user equipment for selecting a set of beams to be monitored by said UE

A method, performed by a user equipment (UE), is provided. The method includes: obtaining a channel hardening (CH) parameter; changing a measurement parameter based on the obtained CH parameter; and adapting a measurement procedure in accordance with the changed parameter. A method performed by a network node, the method includes obtaining a channel hardening (CH) parameter corresponding to a user equipment (UE); and sending to the UE an indication that the UE is allowed to perform optimizations based on the obtained CH parameter.

Measurement adaptation based on channel hardening

Method, base station and a User Equipment for selecting a set of beams to be monitored by said UE

An aspect of an embodiment provides a method for controlling channel quality monitoring in a wireless communication system that utilises beamforming, whereby a plurality of signals are transmitted from a base station to a user equipment and the quality of a received signal is measured at the user equipment for each of the plurality of signals, each of the plurality of signals being transmitted by the base station utilising a different frequency sub-band and beam pairing. The method includes: identifying plural frequency sub-band and beam pairings for which the received signal quality is correlated; and, for each frequency sub-band and beam pairing within a group of plural frequency sub-band and beam pairings for which the received signal quality is correlated, evaluating the periodicity of a received signal quality analysis process, and determining whether or not to adjust the periodicity.

Methods and apparatus relating to a wireless communication network that utilises beamforming

A method in a terminal device of a wireless network, the wireless network further comprising first and second radio access nodes, the method comprising: repeatedly measuring one or more metrics for signals transmitted by the first radio access node and signals transmitted by the second radio access node. A frequency with which the one or more metrics are measured varies as a function of one or more of: a difference between the values of the one or more metrics for signals transmitted by the first radio access node and the values of the one or more metrics for signals transmitted by the second radio access node; and a rate of change of the difference between the values of the one or more metrics for signals transmitted by the first radio access node and the values of the one or more metrics for signals transmitted by the second radio access node.

Methods and apparatus for measurement and measurement reporting in a wireless network

A method of selecting a set of beams to be monitored by a User Equipment, UE, in a telecommunication network, said telecommunication network comprising a Base Station, BS, function coupled to at least one Access Node, AN, serving said UE, said method comprising the steps of receiving measurement data comprising measurements of qualities of beams observed by said UE, wherein said beams originate from said at least one AN to said UE, and originate from at least another AN in said telecommunication network to said UE, retrieving at least one measurement data from a particular UE that matches the received measurement data, wherein the historical database comprises historical measurement data comprising measurements of qualities of beams observed by UE's in said telecommunication network over time, selecting a set of beams to be monitored by said UE based on said retrieved at least one measurement data from said particular UE and based on subsequent measurement data of said particular UE over time in said historical database, and transmitting said selected set of beams to be monitored to said UE.
