Patent number: 8830910Abstract: A wireless communication device includes a transceiver configured for communication using multiple communication modes, the transceiver comprising a transmitter and a receiver. A plurality of antennas is coupled to the transceiver. The plurality of antennas includes a first antenna and a second antenna. The multiple communication modes include a multiple input multiple output (“MIMO”) mode and a single antenna receive mode. The device further includes a control circuit configured to detect selection of the single antenna receive mode as an active one of the multiple communication modes and to automatically alter a configuration of the plurality of antennas and transceiver by configuring the first antenna as a transmit only antenna and the second antenna as a receive only antenna responsive to detection of the selection of the single antenna receive mode. Related methods of operation are also discussed.Type: GrantFiled: December 15, 2010Date of Patent: September 9, 2014Assignees: Sony Corporation, Sony Mobile Communications ABInventor: Filip Skarp
