Abstract
Systems and methods for facilitating inter-cell interference coordination using load indication are described. A UE may receive load indicator signals from a plurality of base stations in adjacent cells and determine, based at least in part on the load indicator signals, a transmit power metric. The transmit power metric may be provided to a serving base station, which may allocate uplink resources based on the transmit power metric. Additional information related to receiver sensitivity and/or path loss may be used to determine the transmit power metric.
Claims16
A method for providing inter-cell interference coordination, comprising:
- receiving a plurality of load indicator signals from a plurality of network nodes operating in one or more adjacent cells;
- determining a transmit power metric based at least, in part, on the plurality of load indicator signals and, in part, on a plurality of path loss values associated with the plurality of network nodes;
- and
- sending the transmit power metric to a serving network node;
- wherein determining the transmit power metric includes determining a plurality of power metrics, the determining of the plurality of power metrics including determining one or more maximum power metrics for each of the plurality of load indicator signals, and
- wherein the transmit power metric is based on a minimum of the plurality of maximum power metrics.
A computer program product comprising a non-transitory computer-readable medium including codes for causing a computer to:
- receive a plurality of load indicator signals from a plurality of network nodes operating in one or more adjacent cells;
- determine a transmit power metric based at least, in part, on the plurality of load indicator signals and, in part, on a plurality of path loss values associated with the plurality of network nodes;
- and
- send the transmit power metric to a serving network node;
- wherein determining the transmit power metric includes determining a plurality of power metrics, the determining of the plurality of power metrics including determining one or more maximum power metrics for each of the plurality of load indicator signals, and
- wherein the transmit power metric is based on a minimum of the plurality of maximum power metrics.
A communications device, comprising:
- a receiver module configured to receive a plurality of indicator signals from a plurality of network nodes operating in one or more adjacent cells;
- a processor module configured
- to determine a transmit power metric based at least, in part, on the plurality of load indicator signals and, in part, on a plurality of path loss values associated with the plurality of network nodes;
- and
- a transmitter module configured to send the transmit power metric to a serving network node;
- wherein determining the transmit power metric includes determining a plurality of power metrics, the determining of the plurality of power metrics including determining one or more maximum power metrics for each of the plurality of load indicator signals, and
- wherein the transmit power metric is based on a minimum of the plurality of maximum power metrics.
A communications device, comprising:
- means for receiving a plurality of load indicator signals from a plurality of network nodes operating in one or more adjacent cells;
- means for determining a transmit power metric based at least, in part, on the plurality of load indicator signals and, in part, on a plurality of path loss values associated with the plurality of network nodes;
- and
- means for sending the transmit power metric to a serving network node;
- wherein the means for determining determines a plurality of power metrics, the determining of the plurality of power metrics including determining one or more maximum power metrics for each of the plurality of load indicator signals, and
- wherein the transmit power metric is based on a minimum of the plurality of maximum power metrics.
