摘要： Methods and apparatus are disclosed for near field radio-frequency (RF) testing of devices, particularly user equipment (UEs) capable of millimeter-wave (mmWave) transmissions. An exemplary test apparatus is described that uses a transducer to facilitate near field over-the-air testing of UEs in the mmWave transmission band. The transducer may be an orthomode transducer and may include a dual-polarity port positioned in the reactive near field of an antenna of a device under test (DUT). For UE signal transmission tests, the orthomode transducer splits test signals received from the antenna of the DUT via the dual-polarity port into a pair of single-polarity RF signals. The single-polarity RF signals are separately fed through a pair of waveguide-to-coaxial adaptors into separate coaxial cables, which feed coaxial transmission versions of the single-polarity RF signals to test equipment for analysis. UE signal reception tests are also described that utilize the same or different orthomode transducer.

摘要： Various embodiments include methods implemented on a wireless communication device for reducing interference during a tune-away from a first subscription to a second subscription when a transmitter remains tuned to the first subscription. The methods may include determining whether the first subscription will utilize the transmitter during the tune-away to the second subscription when the transmitter is operating in envelope tracking mode, and switching the transmitter from envelope tracking mode to average power tracking mode during the tune-away in response to determining that the first subscription will utilize the transmitter during the tune-away to the second subscription. The methods may further include determining whether interference of the receiver by the transmitter exceeds a threshold, switching the transmitter to average power tracking mode during the tune-away if the interference exceeds the threshold, and leaving the transmitter in envelope tracking mode if the interference does not exceed the threshold.
