Abstract: A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders. The method includes sending (405) an indication (304) relating to the selected precoder.

Abstract: 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.

Abstract: A method for beam sweeping in a wireless communication system is described. Beam sweeping includes performing a reduced beam sweep corresponding to a reduced set of beams that are a subset of a full set of beams available for transmitting and/or receiving from an antenna module, without sweeping beams that are not members of the reduced set of beams. The method includes selecting a beam out of the reduced set of beams for transmitting and/or receiving from the antenna module based on the reduced beam sweep without sweeping beams that are not members of the reduced set of beams. Related devices are disclosed.

Abstract: An antenna switching method includes 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, switching 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.
