Abstract: An error correction component and ?T?M compensation function determine correction factors from a feedback signal to use by digital predistortion to cancel distortion caused by a power amplifier and also determine correction factors that may be used to determine Time of Arrival of an isolation leakage signal. Correction factors may be stored in, or retrieved from, multiple ?T?M functions, which may be part of an ASIC along with the error correction component. The isolation leakage signal may be canceled within the error correction component, resulting in a leakage residual signal that may facilitate determining the ToA of the leakage signal. Cancelling the isolation leakage signal facilitates better sensitivity in detecting the presence of, or ToA of, other signals present at the same port of a circulator from which the isolation leakage signal flows to the error correction component.

Abstract: Technology described herein can gather time domain power data for enabling real-time adjustment of one or more parameters of a radio system. In an embodiment, a system can comprise a processor that is configured to control collection of power data from a radio system, a read circuit communicatively coupled to the processor and controlled by the processor to read, at the radio system, the power data in a time domain, across at least a portion of a downlink chain or an uplink chain of the radio system, along a selected time range that is defined by a specified upper limit of time and a specified lower limit of time, and a memory communicatively coupled to the processor and that receives and stores the power data as stored power data in the time domain from the read circuit.

Abstract: A method and network entity for enabling higher order modulation (HOM) mode support for HOM capable wireless devices. The method includes determining a legacy mode power offset value for HOM mode capable wireless devices in legacy modulation mode and calculating a power headroom value for sending downlink data to the HOM mode capable wireless devices. When the power headroom value exceeds a threshold value, the HOM mode support for the HOM mode capable wireless devices is enabled using the identified legacy mode power offset value. When the power headroom value does not exceed the threshold value, and a HOM mode power offset value is available, the HOM mode power offset value being less than the legacy modulation mode power offset value, the HOM mode support for the HOM mode capable wireless devices is enabled using the HOM mode power offset value.
