摘要： 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.

摘要： The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross-polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.

摘要： The present invention relates to an antenna arrangement for use in a wireless communication system, where the arrangement comprises at least two single-polarized antenna functions. Each antenna function is adapted for radiating an antenna radiation lobe pattern having a horizontal extension in an azimuth plane, and a vertical extension in an elevation plane, perpendicular to the azimuth plane. The antenna functions both have a first polarization in a first direction. In a second direction separated from the first direction, the second antenna function has a second polarization and the first antenna function has a third polarization, the second polarization and the third polarization being orthogonal to each other.
