摘要： The present invention relates to handover procedures in a cellular communications system (1). The cells (10-70) of the system (1) are divided into multiple handover-related classes based on their respective radio coverage characteristics. Each such cell class is then associated with a unique handover parameter or a unique set of parameters that are used in handover procedures involving the cells (10-70). The parameter values are adapted for the radio coverage characteristics of each cell class in order to generate a suitable handover region size of the cells (10-70). The handover parameters are used together with user equipment-assisted signal quality measurements for triggering the handover procedures.

摘要： A user equipment (UE) receives a radio signal which includes a time-frequency grid of radio resource elements. A UE detector measures a signal quality parameter associated with a subset of the radio resource elements in the time-frequency grid. The subset of the radio resource elements is less than a total number of the radio resource elements in the time-frequency grid and corresponds to an individual radio channel. Radio circuitry in the UE reports to a network node the signal quality parameter measured for the subset of the radio resource elements in the time-frequency grid to enable an operation related, for example, to the individual radio channel.

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： A basic idea of the invention is to provide multi-user resource scheduling and distribution based on balancing the power resources used for the different narrow beams in order to smooth the interference levels over the whole cell, area and to reduce interference fluctuations. The resource scheduling principle according to the invention is especially useful when the available resources are not fully utilized. The idea is to select, for each antenna beam of at least a subset of the antenna beams, at least two mobile users for service using the respective antenna beam during a transmission time interval, and to distribute power resources to the antenna beams for use during the transmission time interval based on the guideline of balancing the power resources among different antenna.

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.
