  • Publication number: 20180234268
    Abstract: Allocation of CSI-RS or CSI pilot sequences among cells in a cooperative manner to reduce pilot inter-cell interference. Sequences in each cell occupy the same time slot, multiple subcarrier frequencies, and are orthogonal in time via properly chosen cyclic shifts. Sequences in multiple cells are chosen from a pool of non-orthogonal yet distinguishable sequences through their root indices. Exchanging root indices among cells allows a given cell to reconstruct sequences used in neighboring cells and to estimate interfering channels as the number of channel taps is usually limited, thus mitigating pilot contamination. Furthermore, a greedy selection algorithm to find combinations of sequences that further reduce the channel estimation mean-square-error is proposed.

  • Publication number: 20180217346
    Abstract: The disclosure relates to an apparatus for mounting optical components in a manner that self-aligns the optical axes of the optical components. The apparatus uses an optical component mount that includes a housing consisting of a single rail mount configured to mechanically couple to a portion of a rail for supporting the optical component mount on a rail. The housing also has an optical component dock configured to support an optical component in a manner that defines an optical axis. The rail mount and the optical component dock are configured to make the optical axis substantially parallel with a longitudinal axis of the rail. Using such optical component mounts secured to the rail would result in the self-alignment of the optical axes of optical components on the optical component mounts. Various embodiments of such apparatus are also provided in the disclosure.
