Multi-antenna control in wireless user devices

A wireless communication system comprising a first wireless communication device that has first antennas that have first earth-orientations and a second wireless communication device that has second antennas that have second earth-orientations, the wireless communication system comprising:

• the first wireless communication device configured to wirelessly exchange first network signaling with a wireless access node over at least some of the first antennas wherein some of the first network signaling indicates Device-to-Device (D2D) communication times and frequencies;
• the second wireless communication device configured to wirelessly exchange second network signaling with the wireless access node over at least some of the second antennas wherein some of the second network signaling indicates the D2D communication times and frequencies;
• the first wireless communication device and the second wireless communication device configured to wirelessly exchange device signaling with each other over at least some of the first antennas and the second antennas using the D2D communication times and frequencies wherein some of the device signaling indicates the first earth orientations for at least some of the first antennas and the second earth orientations for at least some of the second antennas;
• the first wireless communication device configured to select a first subset of the first antennas based on the first earth orientations and the second earth orientations;
• the second wireless communication device configured to select a second subset of the second antennas based on the first earth orientations and the second earth orientations;
• and
• the first wireless communication device and the second wireless communication device configured to wirelessly exchange user data with each other over the first subset of the first antennas and the second subset of the second antennas using the D2D communication times and frequencies.
