Method and system for optimal allocation of uplink transmission power in communication networks

A method for determining transmission power for a user in a network, the method comprising:

• receiving, by a user, a first plurality of interference indicators for a first control period, the user being associated with a sector, the first plurality of interference indicators corresponding to a first plurality of sectors respectively, each of the first plurality of sectors being associated with one of a first plurality of users and a first base station;
• processing at least information associated with the first plurality of interference indicators;
• selecting a first interference indicator for the first control period from the first plurality of interference indicators based on at least information associated with the first plurality of interference indicators, the selected first interference indicator corresponding to one of the first plurality of sectors, wherein each of the first plurality of interference indicators is respectively associated with an interference metric κj1 broadcast by one sector j1 at an end of the first control period, j1 being an index for representing one of the first plurality of sectors, wherein the interference metric κj1 is defined as a ratio of a quantity that equals to an interference constraint Imax1 predetermined for the sector j1 subtracting a background noise Nj1 at the sector j1 for the first control period over an inter-sector interference Ij1 experienced by the sector j1 at the first control period;
• determining a first gain indicator for the first control period corresponding to both the user and the one of the first plurality of sectors;
• processing information associated with the first gain indicator;
• and
• determining a first uplink transmission power for a second control period based on at least information associated with the first gain indicator and the selected first interference indicator.

A system for determining transmission power for a user in a network, the system comprising:

• one or more components configured to:
• receive, by a user, a plurality of interference indicators, the user being associated with a sector, the plurality of interference indicators corresponding to a plurality of sectors respectively, each of the plurality of sectors being associated with one of a plurality of users and a base station, wherein the plurality of interference indicators each is associated with an interference metric value defined as a ratio of a quantity that equals to a predetermined interference constraint for a sector subtracting a background noise at said sector over inter-sector interferences experienced by the sector from other sectors;
• process at least information associated with the plurality of interference indicators;
• select an interference indicator from the plurality of interference indicators based on at least information associated with the plurality of interference indicators, the selected interference indicator corresponding to one of the plurality of sectors;
• determine a gain indicator corresponding to both the user and the one of the plurality of sectors;
• process information associated with the gain indicator;
• and
• determine an uplink transmission power based on at least information associated with the gain indicator and the selected interference indicator.
