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.

Dependent claims

A method comprising:

detecting, by an end device, a new transmission grant via a downlink control channel, wherein the end device is in a discontinuous reception active state;
determining, by the end device, that the new transmission grant is a potential false grant;
performing, by the end device, a verification procedure pertaining to the potential false grant;
and
determining, by the end device based on a result of the verification procedure, whether the potential false grant is a valid grant or a false grant, wherein when the potential false grant is the false grant, the method further comprising:
omitting, by the end device, to start a discontinuous reception inactivity timer.

3 more elements

A non-transitory, computer-readable storage medium storing instructions executable by a processor of a device, which when executed cause the device to:

detect a new transmission grant via a downlink control channel, wherein the device is in a discontinuous reception active state;
determine that the new transmission grant is a potential false grant;
perform a verification procedure pertaining to the potential false grant;
and
determine, based on a result of the verification procedure, whether the potential false grant is a valid grant or a false grant, wherein when the potential false grant is the false grant, the instructions when executed cause the device to:
omit to start a discontinuous reception inactivity timer.
