Abstract: In an embodiment there is established for a user equipment UE a first discontinuous reception DRX period of a first radio access technology RAT using at least one parameter that is common with a second DRX period of a second RAT for the UE. From the perspective of the network, transmission opportunities to the UE using the first RAT are arranged according to the established first DRX period. From the perspective of the UE, reception opportunities at the UE using the first radio access technology are arranged according to the established first DRX period. There may be one access node or two cooperating access nodes serving the UE with the different RATs. In different embodiments the DRX active periods may be purposefully aligned or misaligned. Examples of such a common DRX parameter include DRX cycle, DRX inactivity timer, and DRX on-duration time.

Abstract: A server cluster is described, which enables load balancing between servers in the cluster. At least some of the servers in the cluster are divided into a plurality of virtual servers, wherein each virtual server is associated with a neighbouring server, which neighbouring server acts as a backup for that virtual server. The neighbouring server of each virtual server of a particular server is part of a different physical server to the virtual server, such that in the event that a physical server is unavailable for use, the load of the virtual servers of that physical server is split between a number of different physical servers, thereby reducing the likelihood of overloading any particular physical server.

Abstract: A mechanism for configuring stations for reference signalling is disclosed. A first station defines a pattern of configuration indications for use in reference signalling and communicates information of the pattern of configuration indications to at least one second station for configuring the at least one second station for reference signalling. After receiving the information of the pattern a second station can obtain information of subframes that associate with reference signalling there from. Upon detection of a trigger by the first station for transmission of a reference signal the second station can be configured for transmission of the reference signal based on the information obtained from the pattern.
