20140105204 | ANTENNA SWAPPING METHODS INCLUDING REPEATEDLY SWAPPING BETWEEN ANTENNAS, AND RELATED WIRELESS ELECTRONIC DEVICES - Antenna swapping methods for a wireless electronic device may include repeatedly swapping back and forth between activating a first antenna and activating a second antenna, and measuring an antenna performance characteristic of the wireless electronic device, during a time period of repeated swapping. The methods may include comparing the antenna performance characteristic of the wireless electronic device during the time period of repeated swapping and an antenna performance characteristic of the wireless electronic device before the time period of repeated swapping. The methods may include, in response to determining that the antenna performance characteristic of the wireless electronic device during the time period of repeated swapping is stronger than the antenna performance characteristic of the wireless electronic device before the time period of repeated swapping, swapping once between the first and second antennas. Related devices are also described. | 04-17-2014 |
20150017929 | ANTENNA SWAPPING METHODS INCLUDING COMPARING PERFORMANCE CHARACTERISTICS OF FIRST AND SECOND ANTENNAS, AND RELATED PORTABLE ELECTRONIC DEVICES - An antenna swapping method may include tuning respective signals provided to first and second antennas in a portable electronic device to at least one frequency band. The method may also include connecting the first antenna to an uplink signal path that is for transmissions through the first and second antennas, and performing impedance matching for the first antenna. The method may further include comparing a real-time performance characteristic of the first antenna with a real-time performance characteristic of the second antenna. The method may additionally include, responsive to determining that the second antenna has a stronger real-time performance characteristic than the first antenna while the first antenna is connected to the uplink signal path, swapping from the first antenna to the second antenna by connecting the second antenna to the uplink signal path and disconnecting the first antenna from the uplink signal path, and performing impedance matching for the second antenna. | 01-15-2015 |

20150215019 | MOBILE COMMUNICATIONS USING BASE STATION CONTROLLED OPTIMIZATION OF ADAPTIVE ANTENNA SELECTION PARAMETERS, TERMINALS WITH ADAPTIVE ANTENNA SYSTEM, AND METHOD - A mobile communications terminal with plural antennas for uplink communications with a network base station in a cell, uses an adaptive antenna selection algorithm to select antennas. A method of operating a mobile communications terminal. The cell operator or base station provides parameters and/or settings to the terminal to determine algorithm behavior in selecting antennas, for example, according to operative characteristics of signals in uplink communications in the network, operation of the terminal, and/or network conditions. A communications method includes sending from a base station one or more parameters and/or settings for a terminal to select which of plural antennas of the terminal to use transmitting signals to the base station. A base station transmits to terminals one or more such parameters and/or settings for use in the adaptive antenna selection algorithm to select antennas for transmitting signals to the base station. | 07-30-2015 |
