Abstract
A method of managing radio resources and a Node B implementing the same are provided. If the total radio resources used in a cell exceed target radio resources signaled by an RNC, uplink rates are equally allocated to primary UEs and non-primary UEs by controlling the signal strengths of the primary and non-primary UEs.
Claims26
A method of managing radio resources between serving uplink channels from first user equipments (UEs) for which a Node B is a serving Node B and non-serving uplink channels from second UEs for which the Node B is a non-serving Node B in a mobile communication system for transmitting packet data on an enhanced uplink, comprising:
- receiving from a radio network controller (RNC) a target total power level for the serving uplink channels and the non-serving uplink channels and a target power ratio of the non-serving uplink channels against the target total power level by the Node B;
- comparing the target total power level with a current total power level of the serving uplink channels and the non-serving uplink channels by the Node B;
- comparing the target power ratio of the non-serving uplink channels with a current power ratio of the non-serving uplink channels against the current total power level, if the current total power level is higher than the target total power level by the Node B;
- and
- commanding the second UEs to decrease data rate of the non-serving uplink channels, if the current power ratio of the non-serving uplink channels is higher than the target power ratio of the non-serving uplink channels by the Node B.
A method of managing radio resources between serving uplink channels from first user equipments (UEs) for which a Node B is a serving Node B and non-serving uplink channels from second UEs for which the Node B is a non-serving Node B in a mobile communication system for transmitting packet data on an enhanced uplink, comprising:
- setting a target total power level for the serving uplink channels and the non-serving uplink channels by a radio network controller (RNC);
- setting a target power ratio for the non-serving uplink channels to the target total power level by the RNC:
- and
- signaling the target total power ratio and the target power ratio of the non-serving uplink channels to the Node B, for use in controlling a data rate of the non-serving uplink channels for the second UEs, by the RNC.
A Node B apparatus for managing radio resources between a serving uplink channels from first user equipments (UEs) for which a Node B is a serving Node B and non-serving uplink channels from second UEs for which the Node B is a non-serving Node B in a mobile communication system for transmitting packet data on an enhanced uplink, comprising:
- a receiver for receiving from a radio network controller (RNC) a target total power level for the serving uplink channels and the non-serving uplink channels and a target power ratio of the non-serving uplink channels against the target total power level;
- a decider for measuring a current power level of the serving uplink channels and a current power level of the non-serving uplink channels;
- a comparator for comparing the target total power level with a current total power level of the serving uplink channels and the non-serving uplink channels, comparing the target power ratio of the non-serving uplink channels with a current power ratio of the non-serving uplink channels against the current total power level, and determining to command the second UEs to decrease data rate of the non-serving uplink channels, if the current total power level is higher than the target total power level and the current power ratio of the non-serving uplink channels is higher than the target power ratio of the non-serving uplink channels;
- and
- a transmitter for signaling and for commanding the second UEs to decrease data rate of the non-serving uplink channels according to the determination of the comparator.
