Abstract
Systems and methodologies are described that facilitate commanding a wireless device to transmit a random access channel (RACH) signal to measure communication parameters related thereto. The wireless device can transmit a RACH preamble upon receiving a command, and one or more parameters can be computed based at least in part on transmitting the command and/or receiving the RACH preamble, such as a round trip time, a received signal power, and/or the like. The one or more parameters can be communicated to the wireless device in a RACH response signal, and can be utilized by the wireless device. The wireless device can utilize the one or more parameters to estimate a distance for position determination, compute a path loss, and/or the like.
