Methods and apparatus for determining a transmit antenna gain and a spatial mode of a device
First Claim
1. A method of determining a spatial mode of a device, the method comprising:
- receiving, by a controller of the device, a first data from a proximity sensor coupled to the controller;
receiving, by the controller, a second data from an accelerometer coupled to the controller;
determining, by the controller, a difference between at least two receive signal strengths, each receive signal strength associated with a different antenna of the device; and
determining, by the controller, the spatial mode of the device based on the first data, the second data, and the difference between the at least two receive signal strengths.

Abstract
Methods and apparatus for determining a transmit antenna gain and a spatial mode of a wireless device (100) are disclosed. The apparatus (100) includes a main receive antenna (112) associated with a first receive signal strength, a diversity receive antenna (114) associated with a second receive signal strength, and a transmit antenna (116). Each of the antennas (112, 114, and 116) is operatively coupled to a controller (102). The controller (102) determines (i) a difference between the first receive signal strength and the second receive signal strength, (ii) a correction factor based on the difference, and (iii) the transmit antenna gain based on the correction factor. In addition, the difference between the first receive signal strength and the second receive signal strength may be used, along with other sensor data (e.g., accelerometer), to estimate the spatial mode (e.g., orientation and hand grip) of the device (100). This spatial mode estimation may be then be used, among other things, to more accurately determine transmit antenna gain.
