Abstract
A method for inter-cell interference coordination (ICIC) by a home evolved NodeB (HeNB) is described. A portion of bandwidth is reserved for a user equipment (UE). Notification of the reserved portion of bandwidth is sent to at least one potentially interfering evolved NodeB (eNB). A data exchange is performed with the UE using the reserved portion of bandwidth. Notification is sent to the potentially interfering eNBs releasing the reserved portion of bandwidth.

A method for inter-cell interference coordination (ICIC) by a home evolved NodeB (HeNB), the method comprising:
- reserving a portion of bandwidth for a user equipment (UE);
- sending notification of the reserved portion of bandwidth to at least one potentially interfering evolved NodeB (eNB);
- performing a data exchange with the UE using the reserved portion of bandwidth;
- and
- sending notification to the at least one potentially interfering eNB releasing the reserved portion of bandwidth.
A method for downlink inter-cell interference coordination (ICIC) by a home evolved NodeB (HeNB), the method comprising:
- performing a data exchange with a user equipment (UE);
- receiving a measurement report;
- reducing a transmit power with a first slew rate;
- and
- increasing the transmit power with a second slew rate.
A method for downlink inter-cell interference coordination (ICIC) by a user equipment (UE), the method comprising:
- measuring a received signal strength for a home evolved NodeB (HeNB);
- preparing a measurement report, wherein the measurement report includes the received signal strength for the HeNB;
