Abstract: Certain aspects of the present disclosure relate to methods and apparatus for Channel Quality Indicator (CQI) reporting after resumption of Long Term Evolution (LTE) after a temporary suspension. In certain aspects, in order to minimize performance penalty to LTE on resumption after an LTE tune away for example to service a different Radio Access Technology, information available from before the LTE tune away may be used in addition to one or more additional parameters for determining how to perform LTE CQI calculation/update after tuning back to LTE. In certain aspects, a decision regarding whether a User Equipment (UE) reports a CQI based on channel conditions before the LTE tune away or reports a CQI based on channel conditions after tuning back to LTE may be based on a value of the Doppler estimate, a time duration of the LTE tune away, or a combination thereof.
