Abstract: The user terminal (UT 1) for a mobile cellular satellite network has an antenna configuration (24) which includes elements (45, 46) which provide selectable generally horizontal and vertical directive patterns (49, 50). Data concerning elevation angle is transmitted in a control channel (BCCH, SACCH) and used by UT1 to determine the elevation angle of the satellite (3a) so that an appropriate antenna directive pattern can be selected depending on elevation angle. In an alternative, maritime mode, each directive pattern is dedicated to a particular one of diverse communication paths from different satellites (3a, 3b) to the user terminal.

Abstract: In a transmitter (100), an error correction encoding section (101) error-correction-encodes transmission data, an interleaving section (102) interleaves the data, a modulating section (103) modulates the data and divides it into signals, multiplying sections (106, 107) multiply each signal by time-varying coefficient varying with time and fed from time-varying coefficient generating sections (104, 105), and antennas (108, 109) transmit the signals after the multiplication. Thus, a desired error correction ability is ensured with a limited interleaving length in a low-speed fading state without inviting increase of the scale of the system and increase of the power consumption, thereby solving the problem of transmission change diversity.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing a data transmission scheme for Narrow-Band Internet of Things (NB IoT). A User Equipment (UE) combines pairs of antenna ports to generate at least first and second combined antennas ports. The UE receives reference signals transmitted in a narrow band region of a larger system bandwidth, and for each combined port, adds the references signals received on resource elements (REs) of each of the combined pair of antenna ports. The UE determines channel estimates for each combined antenna port based on the added reference signals for the combined port.

Abstract: Disclosed herein is a system, apparatus, and method for using an antenna system comprising individually configurable antenna circuitries in a wireless network device to simulate the standard MU-MIMO transmissions as specified in the IEEE 802.11ac standard with antenna beamforming. The individually configurable antenna circuitries can be configured to transmit radio frequency (RF) signals with specific radiation patterns including directional beam patterns. Client devices may be grouped and antenna circuitries may be configured in such a way as to minimize inter-user interference. Frequent sounding-channel state feedback cycles and associated overhead are obviated with antenna beamforming, and no change to standards-compliant client devices is necessary. A better overall performance compared to MU-MIMO based on DSP-based beamforming as specified in the IEEE 802.11ac standard is expected.
