Multi-antenna control in wireless user devices
Wireless communication devices have antennas, and the antennas have earth-orientations. The wireless devices exchange network signaling with a wireless access node over the antennas. Some of network signaling indicates Device-to-Device (D2D) communication times and frequencies. The wireless communication devices exchange device signaling with each other over the antennas using the D2D communication times and frequencies. Some of the device signaling indicates the earth orientations for the antennas. The wireless communication devices select a subset of the antennas based on the earth orientations. The wireless communication devices exchange user data with each other over the selected subset of antennas using the D2D communication times and frequencies.
