  • Publication number: 20190153316
    Abstract: Phosphor, a preparation method for the phosphor, and a light emitting device having the phosphor. The phosphor comprises an inorganic compound which at least comprises an element M, an element A, an element D, and an element R; the element M is one or two elements selected from the group consisting of Lu, La, Pr, Nd, Sm, Y, Tb, and Gd and must comprise Lu; the element A is Si and/or Ge; the element D is one or two elements selected from the group consisting of O, N, and F and must comprise N; the element R is Ce and/or Dy. Since the ionic radius of Lu3+ is smaller than that of La3+, when the inorganic compound comprises element Lu, the original ligand site would be contracted. In order to reduce lattice distortion due to the ligand site contraction, the adjacent ligand site expands, and the photochromic property is adjusted.

  • Publication number: 20190159215
    Abstract: Various examples pertaining to multi-transmit/receive point (TRP) interference control in wireless communications are described. A processor of a user equipment (UE) receives, from a network node, a downlink measurement reference signal and configures an interference measurement resource (IMR) associated with a sounding reference signal (SRS) resource of the UE based on the DL measurement reference signal. The processor measures a channel response of a communication channel between the UE and the network node. The processor also measures an interference using the IMR. The processor then generates a precoder based on the measured channel response and the measured interference. The processor further performs an uplink transmission to the network node using the precoder.

  • Publication number: 20190152120
    Abstract: A system for depositing a composite filler material into a channel of a composite structure includes an end-effector configured to extrude a bead of the filler material into the channel. The filler material can comprise a first group of relatively long fibers, a second group of relatively short fibers and a resin. A drive system is configured to move the end-effector relative to the channel, and a position sensor is configured to detect the position of the bead relative to the channel. A controller is configured to operate the drive system in response to the detected position and to operate the end-effector to heat and compress the filler material so as to orient the longer fibers in a substantially longitudinal direction relative to the channel and the shorter fibers in substantially random directions relative to the channel when the bead is extruded into the channel.

  • Patent number: 10298311
    Abstract: Techniques and examples of overhead reduction for linear combination codebook and feedback mechanism in mobile communications are described. A user equipment (UE) receives from a base station of a network one or more reference signals via a communication link between the UE and the base station. The UE constructs a channel state information (CSI) feedback by utilizing a correlation of channel responses in a frequency domain to reduce feedback overhead. The UE then transmits the CSI feedback to the base station.

  • Publication number: 20190149298
    Abstract: Various examples with respect to generation of reference signals with improved cross-correlation properties in wireless communications are described. A processor of a user equipment (UE) selects a column of a Hadamard matrix to provide a vector and also generates a pseudo-random sequence. The processor scrambles the vector with the pseudo-random sequence to provide a scrambling sequence and performs a cyclic shift on the scrambling sequence to provide a cyclic-shifted scrambling sequence. The processor then generates a reference signal by performing a pi/2-binary phase shift keying (BPSK) modulation on the cyclic-shifted scrambling sequence.
