Claim Text:
1. A method for wireless communications, comprising: receiving, from a first radio access network (RAN), an information element indicating an idle interval, the first RAN based on a time division synchronous code division multiple access (TD-SCDMA) radio access technology; suspending, at a user equipment (UE), operation in the first RAN during a first portion of the idle interval, the suspending comprises ignoring messages interpreted as being received from the first RAN; acquiring synchronization signals from a second RAN during the first portion of the idle interval, the second RAN being based on an time division duplex long term evolution (TDD-LTE) radio access technology and having frame boundaries time-aligned with the first RAN; receiving a downlink reference signal and determining a parameter of the downlink reference signal associated with the second RAN during the first portion of the idle interval; returning to the first RAN after determining the parameter by accepting messages interpreted as being received from the first RAN during a second portion of the idle interval, the second portion occurring later than the first portion and prior to termination of the idle interval; and transmitting an uplink signal in the first RAN during the second portion of idle interval, the uplink signal indicating to the first RAN that the UE has completed measurements in the second RAN.
