A method () for managing Optical Wireless Communication (OWC) in a User Equipment (UE) is disclosed, the UE being configured for Radio Frequency (RF) communication with a network and comprising at least two OWC receivers. The method comprises monitoring a captured luminous flux intensity at the OWC receivers () and, if a captured luminous flux intensity at at least one of the OWC receivers is above a viability threshold (), selecting the OWC receiver having the highest captured luminous flux intensity () and extracting client data from an optical signal received on the selected OWC receiver (). Also disclosed are a UE () configured for RF communication with a network and for OWC, the UE comprising at least two OWC receivers, and a controller () for managing OWC in a UE.

Method and apparatus for optical wireless communication

An intermediate node () for a transport network () is configured such that traffic flows between at least one remote access node () and a central hub node () pass via the intermediate node (). The intermediate node () is configured to selectively process a traffic flow depending on a responsiveness requirement of the traffic flow.

Selective processing of traffic flows based on latency requirements

A method () of controlling traffic flows in a radio communications network, the method comprising steps of: receiving () at a remote node a plurality of traffic flows transmitted from a plurality of radio units; buffering () the traffic flows in a common buffer of the remote node; and causing () a control signal to be sent to a baseband unit when a fill level of the common buffer is predicted to go above a maximum fill level within a pre-set time interval, wherein the control signal is configured to cause an adjustment of a radio resource allocation of one of the plurality of radio units to cause a reduction in a data rate of the traffic flow transmitted from said radio unit.
