  • Patent number: 10848242
    Abstract: An active optical machine-readable tag that is addressable and readable within a line-of-sight of a reader device equipped with a camera, at substantially large distances. The active optical tag and the camera-based reader may use a method of asynchronous communication reducing the flicker associated with the low-frequency optical carrier to a level hardly noticeable by people. The method of transmitting data may include determining length of a repetitive time period not longer than time resolution of a human eye, emitting a first sequence of light pulses within the time period, the light pulses including pulses of complementary colors and pulses of different levels of luminosity; and determining the order of the colors and levels of luminosity of the first sequence of light pulses emitted within the time period to represent a symbol, and to achieve perceived chromaticity and luminosity that is substantially constant to a human eye.

  • Patent number: 10848200
    Abstract: A mesh network comprises a controller and a plurality of mesh-networked devices, operable to communicate with the controller. The controller and the plurality of mesh-networked devices comprise timing units, and are operable to communicate in accordance with a frequency hopping sequence. The mesh-networked devices switch between a transmit mode, in which they are capable of transmitting messages to one or more other mesh-networked device and/or the controller and an inactive mode, in which they are unable to transmit to or receive messages from one or more other mesh-networked devices or the controller. The timing units of the mesh-networked devices are synchronised and the mesh-networked devices are operable to switch to the transmit mode at pseudorandom time intervals.

  • Patent number: 10826578
    Abstract: Precoder weights can be indicated to a carrier unit to increase network efficiency. To indicate precoder weights to the carrier unit, various types of precoding data can be used to schedule user equipment. For example, a baseband unit can compress precoding coefficients for channel state information reference signals for a remote radio unit and for a demodulation reference signal (DMRS) to reduce a signaling cost between the remote radio unit and the baseband unit. Because both the baseband unit and the remote radio unit can have access to the basis vectors the basis vectors can be multiplied by coefficients to transmit the compressed weight of the basis vectors. Thus, allowing the remote radio unit to reconstruct the basis vector for the channel state information reference signals.

  • Patent number: 10798663
    Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.
