Abstract
A control method and device for uplink access transmission power are provided that can control inter-cell interference in a radio communications system. In a radio communications system including a plurality of radio communication devices which control a plurality of cells respectively, each radio communication device detects an uplink access delay in its own cell, compares the uplink access delay with a target delay, and, based on the result of this comparison, controls a value related to uplink access transmission power.
Claims31
A control method of uplink access transmission power in each of a plurality of radio communication devices each controlling cells in a radio communications system, comprising:
- a) detecting an uplink access delay in a cell of the radio communication device;
- b) comparing an amount of access delay obtained from the uplink access delay with a target delay;
- and
- c) controlling a value related to uplink access transmission power based on a comparison result of the b).
A control device of uplink access transmission power in each of a plurality of radio communication devices each controlling cells in a radio communications system, comprising:
- a detector for detecting an uplink access delay in a cell of the radio communication device;
- a comparator for comparing an amount of access delay obtained from the uplink access delay with a target delay;
- and
- a controller for controlling a value related to uplink access transmission power based on a comparison result of the comparator.
A radio communication device which controls a cell of its own in a radio communications system including a plurality of cells, comprising:
- a detector for detecting an uplink access delay in the cell;
- a comparator for comparing an amount of access delay obtained from the uplink access delay with a target delay;
- and
- a controller for controlling a value related to uplink access transmission power based on a comparison result of the comparator.
A radio communications system including a plurality of cells, comprising a plurality of radio communication devices which control the plurality of cells, respectively,
- wherein each of the radio communication devices comprises:
- a detector for detecting an uplink access delay in the cell;
- a comparator for comparing an amount of access delay obtained from the uplink access delay with a target delay;
- and
- a controller for controlling a value related to uplink access transmission power based on a comparison result of the comparator.
A computer program for instructing a computer to control uplink access transmission power in a radio communication device controlling a cell in a radio communications system, comprising:
- detecting an uplink access delay in the cell;
- comparing an amount of access delay obtained from the uplink access delay with a target delay;
- and
- controlling a value related to uplink access transmission power based on a comparison result of the comparing.
