    Abstract: A cellular communications network includes a plurality of cells whose base stations (122) have smart antenna capabilities and conventional sector antenna capabilities. At mobile station (142) call setup, the call is initially set up on a sector antenna supported, looser frequency reuse plan assigned, measurement traffic channel frequency provided by the serving base station. Higher quality direction of arrival angle measurements (210) are then made at the serving base station to identify a particular smart antenna narrow beam which could serve the mobile station. A replacement frequency supported by that narrow beam is then selected (214), and an intra-cell handoff of the call is ordered (216). In the event mobile station location information is needed (e.g., based on the call type or call priority), neighbouring base stations are instructed (304) to make (306) and report (308) on direction of arrival angle measurements towards the mobile station. The reported angles are then processed (310) using triangulation (or other suitable) techniques, in view of known base station geographic location, to determine an approximate location of the mobile station.

    Abstract: The present invention relates to methods and arrangements in a wireless communication system that enable the allocation of resources to UEs based on measurements of their antenna polarization, in order to suppress the interference between different UEs at a very low overhead cost. This is achieved by a solution where the scheduling unit retrieves information about the polarization of the UE antenna configurations, and based on this information allocates radio resources to the different UEs, with the aim to minimize the interference. The scheduling unit may retrieve the information from the RBSs or from the UEs. The RBS and the UE will determine the polarization and transmit information regarding this polarization to the scheduling unit. The scheduling unit coordinates the allocation of resources with other scheduling units if necessary.
