  • Patent number: 10356727
    Abstract: For each UE, a base station determines the number of streams for transmitting a data signal, performs different precoding on the data signal depending on the UE, and allocates different transmission powers to at least two UEs. The base station transmits streams addressed to the at least two UEs in a form in which these streams are non-orthogonally mixed, with transmission powers that are different for the UEs. For each of the streams addressed to these UEs, the base station estimates predictive indices for these UEs from channel state information determined by the UEs to which those streams are addressed, and, based on the predictive indices, allocates different transmission powers to those UEs such that the better the predictive index is, the lower the transmission power is.

  • Patent number: 10326500
    Abstract: Embodiments of the present disclosure support a head-mounted display (HMD) wirelessly coupled to a console. The HMD includes a positional tracking system, a beam controller and a transceiver. The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.

  • Patent number: 10299227
    Abstract: A method for dynamically controlling the transmit power of transmission streams transmitted via multiple antennas is disclosed. A transmit power level for multiple streams is determined based on a first reference channel. The difference of signal to interface ratios (SIRs) between two reference channels may represent a power offset. The power offset may be used to determine gain factors used to transmit data channels on the secondary stream with reference to the gain factor of the first reference channel. The power offset may be used to determine other parameters, such a serving grant or transport block sizes of channels carried on the secondary stream. The power offset may allow transmission parameters of channels on the secondary stream to be determined based on the transmit power level of the primary stream and a gain factor for a reference channel transmitted via the primary stream.

  • Patent number: 10278133
    Abstract: A system and method for controlling uplink power to combat rain fade in satellite communication systems. First communication signals transmitted from a satellite to a satellite operations center are monitored at a gateway. A downlink attenuation level is determined for the first communication signals, and compared to an ideal attenuation level. if the downlink attenuation level exceeds the ideal attenuation level, then a corresponding uplink attenuation level is determined for a second frequency used to transmit second communication signals to the satellite, and converted to a power control command for adjusting an amplifier gain. The second communication signals are transmitted to the satellite at either a compensated power level or a normal power level, depending on whether the downlink attenuation level exceeds the ideal attenuation level.
