  • Publication number: 20220255593
    Abstract: Methods and arrangements are described for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported, and the modes have partly shared signaling. SU-MIMO mode signaling which is not needed for MU-MIMO mode signaling is identified. Data bits of the identified signaling is interpreted to comprise signaling information associated with MU-MIMO mode.

  • Publication number: 20220223650
    Abstract: A memory device includes a cross-point array of magnetoresistive memory cells. Each magnetoresistive memory cell includes a vertical stack of a selector-containing pillar structure and a magnetic tunnel junction pillar structure. The lateral spacing between neighboring pairs of magnetoresistive memory cells may be smaller along a first horizontal direction than along a second horizontal direction, and a dielectric spacer or a tapered etch process may be used to provide a pattern of an etch mask for patterning first electrically conductive lines underneath the magnetoresistive memory cells. Alternatively, a resist layer may be employed to pattern first electrically conductive lines underneath the cross-point array. Alternatively, a protective dielectric liner may be provided to protect selector-containing pillar structures during formation of the magnetic tunnel junction pillar structures.
