Abstract: Mobile broadband traffic has been exploding in wireless networks resulting in an increase of interferences and reduced operator control. Networks are also becoming more heterogeneous putting additional demand in interference management. Scheduler schedules uplink transmissions from UEs based on a load prediction algorithm that typically assumes worst case. However, UEs do not always use full power granted, and thus, much of granted radio resources are wasted. To address these and other issues, techniques to accurately predict/estimate other cell interferences and thermal noise separately and to accurately predict/estimate load utilization probabilities, rise-over-thermals, and load factor biases are described. The described techniques are applicable in a radio network node with any number of antenna branches. The techniques can be used to schedule UEs to more fully utilize available radio resources. Extended Kalman filtering can be adapted for use in estimation providing low order computational complexity.

Abstract: An uplink signaling method is described where the UE transmits an indication of its ability to maintain relative transmit phase continuity with respect to a plurality of transmit chains thereof in place of being required to actually maintain the phase difference between its transmitters. The signaling method utilizes straightforward signaling with very little overhead, because the indication may be provided by setting the value of a bit in an uplink transmission. In response, a base station adopts an uplink transmission format for communications by the UE based, at least in part, upon the received indication.

Abstract: Methods, apparatus and systems are provided for assigning Fiber Channel Domain identifiers with an iSNS Server, a Fiber Channel over Ethernet device interconnection apparatus controller (FIAC), and a Fiber Channel over Ethernet device interconnection apparatus (FIA). A Request Domain Identifier iSNS protocol message is sent from a FCoE device interconnection apparatus controller (FIAC) to a iSNS Server.
