Delayed and bundled retransmissions for low bandwidth applications

A mobile device, comprising:

• at least one transceiver configurable to communicate via a long term evolution (LTE) network;
• one or more processors;
• and
• a storage device storing executable instructions that, when executed by the one or more processors, cause the mobile device to:
• identify a downlink transmission from a network base station as erroneous;
• transmit a negative acknowledgement (NACK) message as part of a hybrid automatic repeat request (HARQ) communication to the network base station using the at least one transceiver;
• and
• in response to a delayed HARQ retransmission, remain inactive during a sleep mode of operation of the mobile device to conserve power.

A non-transitory computer-readable medium storing executable instructions that, when executed by one or more processors of a network base station, cause the network base station to:

• monitor a physical uplink control channel (PUCCH) for hybrid automatic repeat request (HARQ) information;
• receive a negative acknowledgement (NACK) message from a user equipment (UE) via the PUCCH;
• and
• in response to receiving the NACK message, delay a HARQ retransmission for the UE such that the UE can remain inactive during an OFF duration of a connected mode discontinuous reception (C-DRX) cycle of the UE.
