1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code, said at least one memory and computer program code being configured to, with said at least one processor, cause the apparatus to perform at least the following:
determine a signal strength of interfering signals received at an antenna array within a user equipment;
determine a dominant interfering ratio indicative of a strength of a strongest interfering signal relative to a strength of at least one other interfering signal;
compare said dominant interfering ratio to a predetermined ratio value; and
where said dominant interfering ratio exceeds said predetermined ratio value, generate a beam forming signal for applying to at least one of amplitude and phase shift circuitry associated with the antenna array to generate a radiation pattern comprising a beam and at least one steered null.
