After a maximum noise rise for a cell is set, a maximum noise rise for each mobile station is allocated within the cell. The actual noise rise from each mobile station within the cell is measured at a base station and signaled to a network. When the cell uses enhanced dedicated channel (E-DCH), the contribution to noise rise of E-DCH signaling is determined and received signal code power (RSCP) at the base station is measured. The RSCP measurement is decoded to determine contributions from mobile stations within and outside the cell; contributions from mobile stations within the cell are calculated; and the network is notified of the measured noise rise. In addition a compensation value may be applied to compensate for temperature induced noise.

Method of controlling noise rise in a cell

In a method for communication by radio a first network radio station allocates radio resources to a subscriber station and communicates with the subscriber station using a portion of the radio resources. A second network radio station uses another portion of the radio resources to send a signaling signal which is intended exclusively for the subscriber station. The first network radio station and/or the second network radio station receives a message from the subscriber station, acknowledging receipt of the signaling signal. In response to the message from the subscriber station, the communication of the subscriber station is handed over from the first network radio station to the second network radio station.

Handover in a radio communication system

Codes are assigned and scheduled for data transmissions, between a radio station and at least one subscriber station, over a wireless interface of a radio communication system, in such a way that both for transmissions in the upward direction (uplink), from subscriber stations to the radio station, and also for transmissions in the downward direction (downlink), from the radio station to subscriber stations, the lowest possible signal-to-average ratio can be achieved.
