Apparatus and methods are disclosed for positioning an access terminal in a CDMA wireless communication network utilizing a highly detectable pilot (HDP) scheme. Here, transmissions by base stations are divided in the time dimension into a plurality of time slots, or pilot control groups (PCGs). A subset of these time slots, according to a duty cycle, are exclusively allocated to the transmission of the HDP signals, while conventional data, control, and pilot transmissions are forgone during these HDP time slots. Among the HDP time slots, in accordance with a re-use pattern, groups of the cells take turns transmitting the HDPs at full base station power. In this way, access terminals are better capable of receiving a greater set of pilot signals for utilization in trilateration of the access terminals. Other aspects, embodiments, and features are also claimed and described. |
