Cell partitioning for high-speed users

Abstract : The present invention relates to a radio access arrangement for operating a radio cell (C), and comprising at least one wireless transceiver (210) configured to set up and operate radio communication channels with mobile devices. In accordance with an embodiment of the invention, the radio access arrangement further comprises speed determination logic (240) configured to characterize a particular mobile device (320) as belonging to a high-speed or lower-speed category (HS; LS) according to speed information of the particular mobile device, and a radio resource controller (250) configured to assign a particular radio communication channel, for communication with the particular mobile device, within a first or second disjoint radio resource partition of the radio cell (B_DL1; B_UL1; B_DL2; B_UL2) if the particular mobile device is characterized as belonging to the lower-speed or high-speed category. The radio access arrangement further comprises a transmit power controller (213) configured to control a transmit power used for communication over the particular radio communication channel as being lower than a first or second substantially higher maximum transmit power level (PTXMAX_DL1; PTXMAX_UL1; PTAX_MAX_DL2; PTXMAX_UL2) if the particular radio communication channel is assigned within the first or second radio resource partition respectively, thereby yielding a long-reach radio coverage area (340) for high-speed mobile devices and a shorter-reach radio coverage area (330) for lower-speed mobile devices. The present invention also relates to a method for operating a radio cell, and to a method for configuring radio resources of radio cells.
