CALIBRATION AND TRACKING TO ASSIST INTER-FREQUENCY MEASUREMENTS OF LTE CELL BY WLAN RADIO

摘要

An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.

1. A method of wireless communication of a user equipment (UE), comprising:
obtaining a first metric based on signals received by a wireless wide area network (WWAN) radio tuned to a first frequency; obtaining a second metric based on signals received by a wireless local area network (WLAN) radio tuned to the first frequency; and determining at least one calibration factor based on the first metric and the second metric.
