Claim Text:
1. An apparatus comprising: a phase shifter configured to provide a phase shift to an element of an array of antenna elements by switching between a set of bit states that correspond to a discrete set of phase shifts, the set of bit states including a current bit state, the set of bit states being for a set of bits generated for the phase shifter; and a controller configured to identify a new bit state for the phase shifter, relative to the current bit state, based on a desired phase shift for the element, wherein the desired phase shift comprises a specified phase shift that is to be applied by the phase shifter to steer a beam from the element in a direction, wherein the new bit state minimizes a quantization error and a bit toggle error between the desired phase shift for the element and an actual phase shift that results when the current bit state is switched to the new bit state.
