  • Patent number: 12004069
    Abstract: A method, network node and processor for processing uplink signals transmitted from a wireless device (WD) to provide a combination of quantize-forwarding and decode-forwarding relayed signals in massive multiple input multiple output (MIMO) heterogeneous networks (HetNets). According to one aspect, whether quantize-forwarding or decode-forwarding is used depends on a ratio of a quality of a WD signal received at a Small Cell Base Station (SCBS) to a quality of the WD signal received at a Macro Cell Base Station (MCBS). When the ratio is less than a first threshold, signals received at the SCBS may be quantize-forwarded to the MCBS and when the ratio exceeds a second threshold larger than the first threshold, signals received at the SCBS may be decode-forwarded to the MCBS. When the ratio lies between the first and second threshold, signals received at the SCBS may be quantize-forwarded to the MCB.

  • Patent number: 11996666
    Abstract: A compression die configured to crimp a composite core is disclosed. The compression die includes an outer body having a tool engaging surface, and an inner body coupled to the outer body. The inner body has a crimping area, wherein the crimping area of the inner body includes ten planar surfaces. The ten planar surfaces are positioned at an angle with respect to an adjacent planar surface such that the combination of the ten planar surfaces form a decagon shaped channel. Crimping is performed by the compression die by inserting the composite core into an encasing connector, which is then inserted into the decagon shaped channel of the compression die. A radial force towards the center of the decagon shaped channel is applied until an outer circumference of the encasing connector containing the composite core fully engages a surface area of each of the ten planar surfaces.
