    摘要: Example embodiments may relate to an apparatus, method and/or computer program for beam alignment. The method may comprise splitting an antenna system of a user equipment into a wide beam portion and a narrow beam portion. The method may also comprise receiving, at the user equipment from a network node, a first set of downlink reference signals. The wide beam portion of the antenna system may receive the first set of downlink reference signals. The method may also comprise controlling the narrow beam portion of the antenna system to scan through various angular directions to search for a second set of downlink reference signals. The method may involve receiving, at the user equipment from the network node, the second set of downlink reference signals. The narrow beam portion of the antenna system may receive the second set of downlink reference signals.

    摘要: An apparatus, method and computer program is disclosed. The apparatus may comprise means for providing information associated with an illumination signal, transmitted by an illuminator, back-scatted from a tag and received by an antenna of the illuminator using a first linear polarization configuration. The apparatus may also comprise means for determining that a different antenna polarization is required at the illuminator for the tag. The apparatus may also comprise means for configuring the antenna of the illuminator to use a different one of a plurality of linear polarization configurations for the tag.

    摘要: An apparatus comprising:
    means for obtaining a total delay error that when added to a reference time equivalent to a reference distance between a first antenna and a second antenna 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 transmitted signal by a frequency-variable complex impedance of the first antenna; means for measuring a frequency-variable second delay associated with reflection of a transmitted signal by 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.

    摘要: An apparatus and method for beam steering is disclosed. The apparatus comprises: a beam forming signal generator configured to generate a beam forming signal for applying to at least one of amplitude and phase shift circuitry associated with an antenna array to provide a radiation pattern. A determining means is provided that is configured to determine a signal strength of interfering signals received at the antenna array within a user equipment and to determine a dominant interfering ratio indicative of a strength of a strongest interfering signal relative to a strength of other interfering signals. A comparator is provided that is configured to compare the dominant interfering ratio to a predetermined ratio value and where the dominant interfering ratio exceeds the predetermined ratio value to generate a control signal for controlling the beam forming signal generator to generate a radiation pattern comprising a beam and at least one steered null.
