  • Publication number: 20230345494
    Abstract: Uplink control channel resource allocation for an enhanced downlink control channel is disclosed. A first example method disclosed herein includes receiving, at a user equipment (UE), a downlink control channel carrying a physical uplink control channel (PUCCH) resource indicator, mapping the PUCCH resource indicator to a first offset, mapping a position of the downlink control channel to a second offset, and mapping a linear combination of the first and second offsets to an index identifying a first PUCCH resource. A second example method disclosed herein includes, in response to receiving, at a UE, an indication of a dynamic resource offset in an enhanced physical downlink control channel (ePDCCH) transmitted in a first ePDCCH set, determining a position of the ePDCCH and a subframe offset, and processing the indication of the dynamic resource offset, the position and the subframe offset to determine an allocated uplink control channel resource for the UE.

  • Publication number: 20230139047
    Abstract: Disclosed is a concrete product incorporating rubber aggregate produced by casting under pressure. The concrete product may optionally be cast at 6.9-27.7 MPa for periods of, for example, 24 hours. In one embodiment the rubber aggregate may comprise coarse and/or fine rubber aggregate to replace natural sources of coarse and fine aggregate. Casting under pressure was found to generally improve the performance characteristics of the concrete when compared to corresponding concrete cast without pressure.

  • Publication number: 20210089730
    Abstract: A management system monitors a set of objects of a user by wirelessly communicating with one or more location components associated with the objects, and each object of the set has a respective location component. The monitoring includes ascertaining by the management system, based at least in part on data obtained via wireless communication with the location component(s), a spatial centroid of the set and a spatial separation of an object in the set from the spatial centroid, and correlating the ascertained spatial centroid to a context classification of multiple context classifications. The management system further determines whether a difference between the ascertained spatial separation and the average spatial separation of the location component(s) for the correlated context classification exceeds an acceptable spatial separation tolerance. Based on the difference exceeding the acceptable tolerance, the management system provides an electronic alert to the user.
