TLDR
In this article, a user device determines an orientation of the user device, and selects one of multiple antennas to use as a first transmit antenna based on the orientation of user device and transmits information using the first transmitter antenna.Abstract:
Methods and systems for selecting one of a plurality of antennas to be used as a transmit antenna based on an orientation of a user device are described. A user device determines an orientation of the user device, and selects one of multiple antennas to use as a first transmit antenna based on the orientation of the user device. The user device transmits information using the first transmit antenna.read more

Communication apparatus and communication method
TL;DR: A communication apparatus which communicates data with plural other communication apparatuses by performing wireless communication includes: plural antennas; a communication level obtainment unit which obtains communication levels for the antennas obtained when the communication apparatus performed the wireless communication with the other communication apparatus.
Patent
Selective specific absorption rate adjustment
TL;DR: In this article, a capability of distinguishing between human tissue and other non-human-tissue objects in proximity of the transmission source provides for selective control of SAR adjustments, which can avoid certain communication performance reductions introduced by decreases in transmission power effected to comply with SAR standards.
