  • Array antenna arrangement
    Patent number: 8666451
    Abstract: A wireless communication system comprising at least one base station in a communication cell, wherein the base station is equipped with at least one array antenna comprising at least two antenna ports which are connected to respective at least two corresponding antenna elements, wherein at least two of the at least two antenna elements have essentially the same polarization. The array antenna is arranged for communication via at least two antenna radiation lobes, each antenna radiation lobe communicating an information stream to at least one user equipment (UE) in the cell, wherein each antenna radiation lobe is individually controllable both in azimuth and elevation, whereby the communication of the information streams is optimized.

  • Wireless telecommunications system with improved transmission capacity
    Patent number: 8320357
    Abstract: A wireless telecommunications system for stationary or semi-stationary equipment includes a main node and a first plurality of terminals belonging to the same access subset and arranged to receive from and transmit to the main node. The main node transmits in at least one beam and receives in at least two beams, and the system indicates to the terminals that they may or may not transmit to the central node. Based upon certain criteria, two or more terminals located in different receive beams of the main node may be given permission to transmit to the central node simultaneously. Suitably, two or more terminals which are given permission to transmit simultaneously do so using the same frequency, or the same code, or the same time slot.
