1. A mobile device comprising:
- a plurality of directional antenna elements, wherein at least two directional antenna elements from the plurality of directional antenna elements are configured to radiate in different directions; and
a radio frequency integrated circuit configured to select for use, by the mobile device, a first set of one or more directional antenna elements from the plurality of directional antenna elements based upon selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria.

Abstract
An approach is provided for managing power consumption in mobile devices configured with a plurality of directional antenna elements and a radio frequency integrated circuit (RFIC). The RFIC is configured to select for use, by the mobile device, a first set of one or more directional antenna elements from the plurality of directional antenna elements based upon selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria.

12. A method performed by a mobile device comprising a plurality of directional antenna elements and a radio frequency integrated circuit (RFIC), the method comprising:
-
selecting, at a first time, based upon selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria, a first antenna element from the plurality of antenna elements to use for radio frequency (RF) communications with a first wireless communications device; and selecting, at a second time that is after the first time, based upon the selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria, a second antenna element from the plurality of antenna elements to use for RF communications with a second wireless communications device that is different than the first wireless communications device, and de-selecting the first antenna element to use for RF communications with the first wireless communications device; wherein the second antenna element is different than the first antenna element and the second antenna element radiates in a different direction than the first antenna element. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus comprising:
-
a first wireless communications device comprising a plurality of antenna elements and a beam forming component configured to select for simultaneous use, two or more antenna elements from the plurality of antenna elements; and a mobile device comprising; a plurality of directional antenna elements, wherein at least two directional antenna elements from the plurality of directional antenna elements are configured to radiate in different directions, and a radio frequency integrated circuit configured to; at a first time select, based upon selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria, a first directional antenna element from the plurality of directional antenna elements to use for radio frequency (RF) communications with the first wireless communications device, at a second time that is after the first time select, based upon the selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria, a second directional antenna element from the plurality of directional antenna elements to use for RF communications with the first wireless communications device, and at the second time de-select for use the first directional antenna element; wherein the second directional antenna element is different than the first directional antenna element and the second directional antenna element radiates in a different direction than the first directional antenna element. - View Dependent Claims (19, 20)
