Methods and Apparatus to Perform Reference Signal Measurements in a TDD-LTE System From a TD-SCDMA System

摘要

Methods and apparatus are provided for performing measurement of reference signals in the proper subframes of a first radio access technology (RAT) while operating in a second RAT. For certain aspects, the first and second RATs may be Time Division Duplex Long Term Evolution (TDD-LTE) and Time Division—Synchronous Code Division Multiple Access (TD-SCDMA), respectively. By knowing the correct TDD-LTE downlink and uplink subframe configurations, a user equipment device (UE) may temporarily leave the TD-SCDMA network during an idle interval and perform expedited and accurate measurement of TDD-LTE reference signals without errors from trying to measure reference signals during uplink subframes.
