    CPC classification number: G01S13/82

    Abstract: An apparatus is provided that includes means for obtaining a total delay error that when added to a reference time equivalent to a reference distance between first and second antennas equals a difference between a transmission time of a signal sent via the first antenna and a reception time of the signal received via the second antenna; means for measuring a frequency-variable first delay associated with reflection of a signal from a frequency-variable complex impedance of the first antenna; means for measuring a frequency-variable second delay associated with reflection of a signal from a frequency-variable complex impedance of the second antenna; means for estimating a first portion of the total delay error associated with the first antenna in dependence upon at least the first delay; and means for estimating a second portion of the total delay error associated with the second antenna in dependence upon at least the second delay.

    Abstract: User equipment (UE) may be provided that includes means for: reporting at least one candidate CSI beam index to a network to avoid and/or mitigate a maximum permissible exposure (MPE) event; wherein the user equipment associates at least one candidate antenna of the user equipment to the at least one candidate CSI beam index. An apparatus may also be provided that includes means for: creating a first mapping of antennas to downlink path delay intervals using a wider beam downlink reference signal; creating a second mapping of downlink path delay intervals to downlink spatial filters using different narrower beam reference signals; and controlling the selection of an antenna based on second mapping.

    Abstract: An apparatus including an array of dual-polarized antenna elements. Each antenna element includes a pair of orthogonal polarization feeds, and a coupler configured to couple, in the near field, the orthogonal polarizations. The apparatus also including control circuitry configured to control, for each polarization, for each antenna element, a power adjustment and a phase adjustment applied to signals of the respective polarization feeds. The apparatus further includes measurement circuitry configured to measure, for each polarization, for each antenna element via its respective coupler, a power and/or a phase of a signal transmitted from the respective array. The apparatus also includes calibration circuitry configured to adjust, for each polarization, for each antenna element, the power adjustment and/or the phase adjustment applied to signals of the respective polarization feeds in dependence upon the measurement, for each polarization, of power and/or phase of the signal transmitted from the respective antenna element.
