摘要： Disclosed apparatuses obtain real time performance measurements and adaptively select MIMO antennas to improve MIMO antenna performance under given conditions. A correlation estimator determines an approximation of instantaneous antenna correlation values. One method includes obtaining a CQI measurement for a first antenna and a second antenna of a mobile device. The method proceeds by determining a composite CQI for the two antennas and estimating the antenna correlation for the first antenna and second antenna using the composite CQI. The method may further include performing a table lookup operation in a CQI table that maps composite CQI including at least a first and second MIMO stream to coding rates. The method may further include obtaining an SNR measurement for the first antenna and the second antenna of the mobile device, and estimating the antenna correlation for the first antenna and second antenna using the composite CQI and the SNR measurement.

摘要： An electronic device (200) includes a single antenna (211), a communication circuit (202), and a RFID circuit (207). A switch (212) selectively couples the single antenna to one of the communication circuit or the RFID circuit. For example, the RFID circuit can be coupled to the single antenna when the electronic device is OFF, and the communication circuit can be coupled to the single antenna when the electronic device is ON. Accordingly, RFID information can be received from an RFID communication device when the electronic device is OFF. When the electronic device is ON, an interrupt can cause the switch to connect the RFID circuit to the single antenna, sometimes only for less than a predetermined duration.

摘要： A method, a mobile device, and a computer program product enable capacitive proximity sensing in a mobile device. The method includes determining, by a controller of a mobile device, whether the mobile device is participating in an active phone call. In response to determining that the mobile device is participating in an active phone call, the method further includes determining if an ear speaker mode of the mobile device is enabled. In response to determining that the ear speaker mode of the mobile device is enabled, the method further includes activating a driven shield to at least partially shield a capacitance sensor from sensing object capacitance at a second side of the mobile device that is opposed to a first side with the ear speaker.

摘要： An antenna subsystem of a communication device has an open cavity including an inner opening and lateral and outer sides that define a cavity. The cavity is sized less than required for cavity mode resonance at a millimeter-wave operating frequency. A millimeter-wave antenna element placed at the inner opening of the hollowed section cavity excites evanescent electromagnetic fields in the cavity. A slot antenna is formed in a metallic layer of the outer side of the cavity. A metallic sectioned proximity post has a first section positioned adjacent to and spaced apart from the millimeter-wave antenna element to couple to, and conduct, the evanescent electromagnetic field. The metallic proximity post has a second section positioned adjacent to and spaced apart from the slot antenna to couple at the millimeter-wave operating frequency, enabling re-radiation by the slot antenna.

摘要： An electronic communication device performs a method to detect proximity of an object to the device. The method includes determining a set of mutual coupling values for at least one pair of a plurality of antennas arrays of the electronic communication device. Each mutual coupling value indicates an efficiency of a mutual coupling transmission between an antenna element of a first antenna array of a pair of antenna arrays and an antenna element of a second antenna array of the pair of antenna arrays. The method further includes determining object position relative to the plurality of antenna arrays based on the set of mutual coupling values.

摘要： Disclosed apparatuses obtain real-time performance measurements and adaptively select multiple-input, multiple-output (MIMO) antennas to improve MIMO antenna performance. A correlation estimator determines an approximation of instantaneous antenna correlation values. One method includes obtaining a channel quality indicator (CQI) measurement for first and second antennas of a mobile device. The method determines a composite CQI for the two antennas and estimates the antenna correlation for the first and second antennas based on the composite CQI. The method can include performing a lookup operation in a CQI table mapping composite CQI to coding rates. The method can include obtaining a signal-to-noise ratio (SNR) measurement for the first and second antennas of the mobile device, and estimating the antenna correlation for the first and second antennas based on the composite CQI and the SNR measurement.

摘要： A method and system for reconfiguring over-indexed antenna arrays in mobile devices are provided. For example, the method includes receiving sensor input that indicates an object blocking a first subset of reconfigurable antenna elements but not blocking a second subset of reconfigurable antenna elements of an over-indexed antenna array. The method also includes configuring, based on the sensor input, a number of the antenna elements in the first subset as non-active for radiating energy and a number of the antenna elements in the second subset as active for radiating energy.
