Abstract: Methods and nodes for transmission of downlink control channel signals in a downlink frequency carrier of a wireless communication system, wherein at least two PRB pairs, configurable for the transmission of a downlink control channel have different numbers of time-frequency resource elements available for the transmission of said downlink control channel. The method comprises allocating at least one set S of PRB pairs; arranging time-frequency resource elements from said set S into an aggregation comprising at least one level; determining a set LS of aggregation levels supported for the transmission of a downlink control channel within the allocated set of PRB pairs, based on the number of time-frequency resource elements available for the transmission of a downlink control channel in PRB pairs of the set S; and transmitting the downlink control channel within said set S of PRB pairs.

Abstract: The present invention relates to a method in a network control node of a wireless communication system, said wireless communication system using a system frequency bandwidth for downlink transmissions from said network control node to one or more mobile stations of said wireless communication system; said method comprising the steps of: allocating K number of sets of physical resource units arbitrarily chosen within said system frequency bandwidth for downlink transmissions, wherein K is an integer equal to or larger than 1 and the number of physical resource units of each set is selected from a finite set of allowed values; jointly encoding the frequency positions of the K number of sets of physical resource units into a first unique combinatorial index q; and signalling said first combinatorial index q in the downlink.

Abstract: The present invention relates to a method for power control in a wireless communication system comprising at least one mobile station and N number of coordinated reception points with indices n=1, . . . , N, said coordinated reception points being spatially separated and adapted for receiving transmissions from said mobile station, said method comprising the steps of: estimating a propagation loss metric LUL for said mobile station, said propagation loss metric LUL being a weighted sum of individual propagation losses Ln from said mobile station to said coordinated reception points expressed in dB multiplied with associated weights wn; and using said propagation loss metric LUL for power control of said mobile station. Furthermore, the invention also relates to a method in a network control device, a method in a mobile station, a computer program, a computer program product, a network control device and a mobile station device.
