Abstract
Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.
Claims44
A method of communication, comprising:
- determining a level of excess received interference based at least in part on an out-of-cell interference (loc) level;
- and
- adjusting path loss at a femto node by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed conditions for stable system operation.
An apparatus for communication, comprising:
- an interference controller configured to determine a level of excess received interference based at least in part on an out-of-cell interference (Ioc) level;
- and
- a communication controller configured to adjust path loss at a femto node by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed conditions for stable system operation.
An apparatus for communication, comprising:
- means for determining a level of excess received interference based at least in part on an out-of-cell interference (Ioc) level;
- and
- means for adjusting path loss at a femto node by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed conditions for stable system operation.
A non-transitory computer-readable medium comprising codes for causing a computer to:
- determine a level of excess received interference based at least in part on an out-of-cell interference (Ioc) level;
- and
- adjust path loss at a femto node by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over- Thermal (RoT) metric to exceed conditions for stable system operation.
