Problems solved by technology

In case of strong adjacent channel interference (ACI), conventional interference based radio resource management can even be eliminated and / or lost throughout the cell due to one interfering station causing adjacent channel interference in the cell

Embodiment Construction

[0022] Referring first to FIG. 1, FIG. 1 is a block diagram illustrating an environment in which the present invention may be applied. That is, the WCDMA system (Wideband CDMA) mobile communication system allows several mobile stations MS1, MS2, MS3 to communicate with a base transceiver station (BTS) 4 in the same cell via a radio interface via corresponding channels CH1, CH2, CH3. A base station may sometimes be referred to as a Node B. In CDMA based systems, the channels are distinguished from each other by means of scrambling codes in a manner known to those skilled in the art.

[0023] WCDMA can have two modes of operation, Frequency Division Duplex (FDD) mode and Time Division Duplex (TDD) mode. In FDD mode, uplink and downlink are transmitted on different frequencies. In TDD mode, uplink and downlink are transmitted on the same frequency, but separated in time. Fifteen time slots are available in TDD mode. Part of the 15 time slots can be used for uplink and the res...

Abstract

The present invention relates to a radio communication system and a method in the system. According to the method radio resources of the system are managed based on information of the bitrate that has been allocated for a station of the radio communication system.

Description

technical field [0001] The present invention relates to radio resource management in telecommunication systems, particularly (but not exclusively) to multiple access telecommunication systems. Background technique [0002] A number of different radio communication systems are known. Radio communication systems provide mobility for mobile stations, ie the ability to move from one location to another. A mobile station may also roam from one network to another if the other network is compatible with the standard to which the given mobile station is compliant, and a roaming agreement exists between the operators of the two networks. A radio communication network is a cellular network composed of cells. A cell may be defined as a service area covered by one or several base transceiver stations (BTS) serving mobile stations (MS) or similar user equipment (UE) over a radio interface. Examples of multiple access cellular radio networks include CDMA (Code Division Multiple Access)...
