Abstract

A method and system for access and uplink power control for a wireless system having multiple transmit points. In one aspect a method operating in a wireless network having a plurality of transmission points (TP) 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 detecting, by the user equipment, a transmission point having a lowest path loss to the user equipment; and transmitting, by the user equipment, a physical random access channel (PRACH) preamble on a PRACH directed to the transmission points having the lowest path losses.
