Abstract: A wireless communication device is provided with an in-device capability of characterizing the coupling between a pair of antennas. The wireless communication device determines the coupling through an operating gain measurement and through calibration gain measurements obtained through test ports.

Abstract: A user equipment (UE) is provided that detunes a receive antenna while a transmit antenna transmits. To determine the detuning, the UE first transmits a signal through the transmit antenna while the receive antenna is sequentially coupled through known loads. At each load, the UE determines an input reflection coefficient for a transmit path to the transmit antenna. Based upon the known loads and the corresponding input reflection coefficients, the UE determines a load to couple to the receive antenna to perform the detuning.

Abstract: An antenna detuning method includes: time domain duplexing signal transmission and signal reception by a first antenna of a wireless communication device; providing one or more first indications of time domain duplexing and one or more second indications of signal transmission to a semi-autonomous hardware controller of the wireless communication device; and responding, at the semi-autonomous hardware controller of the wireless communication device, to the one or more first indications of time domain duplexing and the one or more second indications of signal transmission by coupling a second antenna of the wireless communication device to receive circuitry during signal reception by the first antenna and to a termination during signal transmission by the first antenna.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for complying with radio frequency (RF) exposure limits via device positioning relative to a human body. An example method of wireless communication includes obtaining first information associated with one or more sensors. The method further includes obtaining second information associated with a mode of using the wireless device. The method further includes determining a position of the wireless device relative to a human body based at least in part on the first information and the second information. The method further includes transmitting a signal at a transmit power in compliance with an RF exposure limit based at least in part on the determined position of the wireless device.

Abstract: A user equipment (UE) is provided that includes an antenna switch array for demultiplexing a reference signal sequentially to each antenna in a plurality of antennas. While the antenna switch array selects an antenna, the UE measures a reflection coefficient for the antenna. The UE then tunes the antenna responsive to the reflection coefficient measurement.
