Abstract: Methods, apparatus and systems for motion-predictive beamforming are disclosed. A method for motion predictive beamforming includes determining a time of a predicted transmission and determining a future position of a virtual reality (VR) receiving device at the time of the predicted transmission. Beamforming parameters are forwarded wireless system that correspond to the future position of the VR receiving device, the time of the predicted transmission, and an error correction margin to cause a transmission of a beam that is formed based on the future position of the VR receiving device, the time of the predicted transmission, and the error correction margin.

Abstract: A system, various methods, and a specific apparatus are provided for the purpose of supporting push-to-talk (PTT) service for a very large group featuring a significantly higher number of listeners than the number of potential talkers, as well as a constrained vocabulary in normal usage. The invention takes advantage of speech-to-text and text-to-speech conversion in end user devices for maximum utterance compression. The invention uses the Iridium Mobile Satellite Service (MSS) system and its Short Burst Data (SBD) service for unicast transmission of talker utterances to a PTT Server, and the same system's Global Data Broadcast (GDB) service for multicast retransmission of utterances from the PTT Server to an effectively unlimited number of listeners. The PTT Server provides priority ordering and preemption as necessary when multiple talkers provide near-simultaneous utterances, effectively managing the floor without interactive protocols among the talkers.

Abstract: A radio access node is configured to digitize a first analog radio frequency signal in order to generate first digital data indicative of the first analog radio frequency signal and is configured to digitize a second analog radio frequency signal in order to generate second digital data indicative of the second analog radio frequency signal. The first analog radio frequency signal is broadcast from a first mobile unit using a first air interface. The second analog radio frequency signal is broadcast from a second mobile unit using a second air interface. The first and second digital data are transported from the radio access node to the base unit using a shared transport medium. The base unit is configured to produce information derived from the first digital data and the second digital data that is used in performing base station processing for the first mobile unit and the second mobile unit.
