Efficient operation of user equipment in a wireless communication network

A User Equipment, UE, configured for operation in a wireless communication network, the UE being configured for Discontinuous Reception, DRX, operation with a DRX cycle having a DRX ON period in which the UE is in a DRX awake state and ready for reception and a DRX OFF period in which the UE is in a DRX sleep state, the UE being configured to:

• determine whether an uplink packet to be transmitted is delay tolerant;
• and
• delay, when the uplink packet is regarded as delay tolerant, a request for an uplink transmission grant for the uplink packet until a DRX ON period of the UE.

A wireless device for operation in a wireless communication network, the wireless device being configured for Discontinuous Reception, DRX, operation with a DRX cycle having a DRX ON period in which the wireless device is in a DRX awake state and ready for reception and a DRX OFF period in which the wireless device is in a DRX sleep state, wherein the wireless device comprises:

• a determination module for determining whether an uplink packet to be transmitted is delay tolerant;
• and
• a delay module for causing, when the uplink packet is regarded as delay tolerant, a delay of the uplink packet in dependence on the DRX state of the wireless device.

A computer memory storing a computer program for operating, when executed by a processor, a wireless device in a wireless communication network, the wireless device being configured for Discontinuous Reception, DRX, operation with a DRX cycle having a DRX ON period in which the wireless device is in a DRX awake state and ready for reception and a DRX OFF period in which the wireless device is in a DRX sleep state, the computer program comprises instructions executable by the processor that cause the processor:

• determine whether an uplink packet to be transmitted is delay tolerant;
• and
• cause, when the uplink packet is regarded as delay tolerant, a delay of the uplink packet in dependence on the DRX state of the wireless device.

A method performed by a radio network node for configuring a User Equipment, UE, for operation in a wireless communication network, the method comprising:

• the radio network node allocating transmission opportunities to the UE for transmitting requests for uplink transmission grants in dependence on the DRX ON period of a DRX cycle of the UE;
• and
• the radio network node transmitting configuration information representative of the allocated transmission opportunities to the UE for enabling configuration of the UE.
