C-DRX Modification Based on Mobility and Signal Conditions

An apparatus, comprising a processing element configured to cause a wireless user equipment (UE) device to:

• establish a radio resource control (RRC) connection with a base station providing a cell of a cellular network;
• configure connected mode discontinuous reception (C-DRX) with the base station, wherein configuring the C-DRX comprises selecting a first C-DRX cycle length;
• detect a first one or more conditions configured to trigger the UE device to request a first C-DRX reconfiguration;
• transmit a request for the first C-DRX reconfiguration to the base station based on detecting the first one or more conditions, wherein the first C-DRX reconfiguration specifies a second C-DRX cycle length, less than the first C-DRX cycle length;
• reconfigure the C-DRX with the base station based on the request for the first C-DRX reconfiguration;
• detect a second one or more conditions configured to trigger the UE device to request a second C-DRX reconfiguration;
• determine a data traffic pattern of one or more applications executing on the UE device;
• determine a third C-DRX cycle length based on the second one or more conditions and the data traffic pattern of the one or more applications executing on the UE device;
• transmit a request for the second C-DRX reconfiguration to the base station based on detecting the second one or more conditions, wherein the second C-DRX reconfiguration specifies the third C-DRX cycle length, larger than the second C-DRX cycle length;
• and
• reconfigure the C-DRX with the base station based on the request for the second C-DRX reconfiguration.

A user equipment (UE) device, comprising:

• an antenna;
• a radio coupled to the antenna;
• and
• a processing element coupled to the radio;
• wherein the antenna, the radio, and the processing element are configured to:
• establish a radio resource control (RRC) connection with a base station of a cellular network;
• receive connected mode discontinuous reception (C-DRX) configuration information indicating a first C-DRX cycle length;
• determine a first one or more conditions of the UE device;
• transmit a request for a first C-DRX reconfiguration to the base station based on detecting the first one or more conditions;
• reconfigure the C-DRX with the base station based on the request for the first C-DRX reconfiguration;
• determine a second one or more conditions of the UE device;
• determine a data traffic pattern of one or more applications executing on the UE device;
• determine a second C-DRX cycle length based on the second one or more conditions and the data traffic pattern of the one or more applications executing on the UE device;
• transmit a request for a second C-DRX reconfiguration to the base station based on detecting the second one or more conditions, wherein the second C-DRX reconfiguration specifies the second C-DRX cycle length;
• and
• reconfigure the C-DRX with the base station based on the request for the second C-DRX reconfiguration.

A non-transitory computer readable memory medium comprising program instructions that, when executed, cause a wireless user equipment (UE) device to:

• establish a radio resource control (RRC) connection with a base station providing a cell to the UE device;
• receive first connected mode discontinuous reception (C-DRX) configuration information indicating a first C-DRX cycle length;
• determine to request a first C-DRX reconfiguration to reduce the C-DRX cycle length based on a first one or more conditions experienced by the UE device;
• transmit a request for the first C-DRX reconfiguration to reduce the C-DRX cycle length to the base station based on determining to request the first C-DRX reconfiguration to reduce the C-DRX cycle length;
• and
• receive first C-DRX reconfiguration information modifying the C-DRX configuration to reduce the C-DRX cycle length from the base station in response to the request for the first C-DRX reconfiguration;
• reconfigure the C-DRX configuration based on the first C-DRX reconfiguration information;
• determine to request a second C-DRX reconfiguration to increase the C-DRX cycle length based on a second one or more conditions experienced by the UE device and a data traffic pattern of one or more applications executing on the UE device;
• transmit a request for the second C-DRX reconfiguration to increase the C-DRX cycle length to the base station based on determining to request the second C-DRX reconfiguration to increase the C-DRX cycle length;
• receive second C-DRX reconfiguration information modifying the C-DRX configuration to increase the C-DRX cycle length from the base station in response to the request for the second C-DRX reconfiguration;
• and
• reconfigure the C-DRX configuration based on the second C-DRX reconfiguration information.
