Abstract
Methods and apparatus for uplink power control in a communication system with a low power cell neighboring a macro cell. The low power cell includes a low power node serving a user equipment (UE). The macro cell includes a base station serving one or more other UE(s). The low power node is configured to determine a power offset between the macro cell and the low power cell. The received power spectral density target for the UE calculation is based on the minimum of a first signal strength target for the UE and estimated noise and interference power(s), or a second signal strength target for the UE and the calculated power offset. The uplink power control for the UE is adjusted based on the calculated received power spectral density target. The first signal strength target may be based on the signal-to-interference-plus-noise ratio target for the UE and the second signal strength target may be based on a signal strength derived from a signal-to-noise ratio target for the UE.
