Dynamic antenna selection based on user hand position

摘要

Embodiments of the disclosure provide systems and methods for improving user equipment performance by implementing antenna selection based on measurement of performance parameters of a plurality of antennas. In some embodiments, the antenna parameter measurements comprise radiated power. In other embodiments, the antenna parameter measurements comprise reflected power. In various embodiments, the antenna parameter measurements may be based on data from sensors that are operable to detect operational characteristics of the plurality of antennas based on the proximity of a portion of a user's body to the sensors. The antenna parameter measurements are then used to select one of the antennas within the plurality of antennas for transmitting and receiving data signals by a wireless communication device.

主权项

1. A wireless device, comprising:
a plurality of antennas; processing logic operable to: measure a predetermined power parameter of said plurality of antennas; select a first antenna, within said plurality of antennas, having a highest first value for said predetermined power parameter; use said first antenna for signal transmissions and reception during a first time interval; continue using said first antenna for signal transmissions and reception at the beginning of a second time interval Immediately following the first time interval; measure a second value of said predetermined power parameter for said first antenna during the second time interval; continue using said first antenna for signal transmission and reception during the second time interval if said second value of said predetermined power parameter is equal to or higher than said first value; and measure the predetermined power parameter of said plurality of antennas during the second time interval to select the antenna, within said plurality, having the highest second value of said predetermined power parameter for signal transmissions and reception in the second time interval if said second value of said predetermined power parameter for the first antenna is less than said first value of the predetermined power parameter for the first antenna.
