  • Publication number: 20210274441
    Abstract: A method, a device, and a non-transitory storage medium provide a false grant detection service. An end device may receive downlink control information when in a discontinuous reception active state. The downlink control information may include a new downlink transmission grant or a new uplink transmission grant. When downlink data pertaining to the new downlink transmission grant is unsuccessfully decoded, the end device may identify the new downlink transmission grant as a potential false grant and invoke a verification procedure. Depending on the result of the verification procedure, the end device may or may not start a discontinuous reception inactivity timer depending on whether the potential false grant is deemed a false grant or a valid grant. Similarly, the end device may invoke a verification procedure for a new uplink transmission grant. The detection of false grants may minimize the waste of power for the end device.
