  • Publication number: 20220312436
    Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

    Abstract: A copper foil, intended for use as a current collector in a lithium-containing electrode for a lithium-based electrochemical cell, is subjected to a series of chemical oxidation and reduction processing steps to form a field of integral copper wires extending outwardly from the surfaces of the current collector (and from the copper content of the foil) to be coated with a resin-bonded porous layer of particles of active electrode material. The copper wires serve to anchor thicker layers of porous electrode material and enhance liquid electrolyte contact with the electrode particles and the current collector to improve the energy output of the cell and its useful life.
