An apparatus for capturing a signal of interest, e.g., PSS and/or SSS, captures data transmitted by a first RAT by obtaining access to a receive chain for a second RAT during a measurement gap for the first RAT. The signal of interest transmitted by the first RAT is captured during the measurement gap using the receive chain for the second RAT. Access to a receive chain for the second RAT may be obtained in any one of several ways. For example, access may be obtained by 1) requesting receive chain access for the second RAT for LTE measurements through a virtual flow, 2) entering into a power save mode, 3) tuning to a non-operating channel, 4) setting network allocation vector (NAV) at or above a threshold value, or 5) entering a measurement mode during which the receive chain for the second RAT is prevented from performing WLAN operations.
