Abstract: A wind noise analyzing apparatus comprises non-stationary CFD calculating measure for running a non-stationary CFD simulation to make a structure model run to calculate an average fluid velocity and an average vorticity in a predetermined period of time of a flow field within a predetermined region out of a flow field around the model for every spatial node within the region as well as to calculate a value based on an amplitude of a disturbed fluid velocity within the region for every spatial node in an angular frequency band-of-interest and acoustic pressure density source calculating measure for calculating, based on these calculated values, an acoustic pressure density source which is an index showing a degree of contribution of a flow field at a spatial node within the region to a surface acoustic pressure fluctuation in an angular frequency band-of-interest at a target point-to-be-analyzed.

Abstract: An enhanced solution for controlling a handover procedure for handing a terminal device over from a source cell to a target cell in a communication network with relay nodes is provided. In the solution, the relay nodes actively assist in the handover procedure by, for instance, initiating the handover procedure, configuring a relayed link and buffering user data at the relay node.

Abstract: The application relates to wireless transmission of load status information for load balancing among Home Node Bs (HNB) or Local Area Node Bs (LNB) for which an X2 interface is not available. In particular, an LNB may pretend to be a user equipment with a specific predefined user equipment ID value. A neighbouring LNB which receives a data packet with this user equipment ID value knows that the data packet contains load information monitored, by a neighbouring LNB.

Abstract: The invention is related to a network element, comprising: means for receiving an upper limit of a network resource, means for determining a user device-specific upper limit for another or same network resource taking into account the upper limit; and means for allocating internal resources of the network element to a predetermined user according to the user device-specific upper limit.

Abstract: A transmitter for a packet radio network, including means for transmitting a signal including data packets to a receiver, means for receiving acknowledgement messages from the receiver, each acknowledgement message indicating whether or not a data packet was received successfully, and means for adjusting transmit power of the signal in the transmitter on the basis of one or more acknowledgement messages.
