Abstract:
1. A method at a user equipment operating in a wireless network having a plurality of transmission points including a macro evolved Node B (‘eNB’) and at least one low power node (‘LPN’) having transmit power lower than that of the macro eNB, the method comprising: finding, at the user equipment, at least two reference transmission points, one of the at least two reference transmission points having a lowest path loss to the user equipment, the lowest path loss being calculated based on a received transmission point specific signal and a received transmit power of the one of the at least two reference transmission points; performing, by the user equipment, uplink power control calculated based on a function of the path loss from the at least two reference transmission points; and signaling, at any time after the finding, at least one of the reference transmission points to a network element in the wireless network.
