    摘要： A system (1) comprises a first and a second node (2i) for a cellular network, each node (2i) having at least two different beams (8i,k) for wireless communication with a user equipment (3) via one of the beams (8i,k) , wherein each beam (8i,k) of the first node (21) covers a different one of a first succession of sections (101,k) of a track (4), each beam (82,k) of the second node (22) covers a different one of a second succession of sections (102,k) of the track (4), the last section (101,3) in the first succession and the first section (102,1) in the second succession coincide, and the first node (21) sends a handover request (HR) regarding a user equipment (3) to the second node (22) when the beam (8i,k) selected for wireless communication with said user equipment (3) changes from the beam (81,2) that covers the last but one section (81,2) of the first node (21) to the beam (81,3) that covers the last section (81,3) of the first node (21).

    摘要： An ad hoc radio base station and a method for locating a user apparatus are presented. The method comprises setting up (400) two ad hoc cells, a first cell of the two ad hoc cells providing an omnidirectional cell and a second cell of the ad hoc cells providing a directional cell, utilizing a set of directional or beamforming antennas, the main lobes of the antennas of the cells being directed at different directions from each other, one antenna of the second cell being active at a time; setting up (402) a radio connection in one of the two ad hoc cells to an user apparatus; obtaining (404) information on the signal-to-noise ratio measured by the user apparatus from of the signal received by the user apparatus and Timing Advance required on the radio connection; transmitting (406) a redirection message to other cell of the two ad hoc cells in the first radio connection to the user apparatus, repeating (408) the above obtaining and transmitting steps a given number of times, and determining (410) the location of the user apparatus based on the obtained information.
