APPARATUS, METHODS, AND COMPUTER PROGRAM PRODUCTS PROVIDING POWER SAVINGS IN SPS-CONFIGURED VOLTE WITH C-DRX
Abstract:
Apparatus, methods, and computer program products providing power savings in Semi-Persistent Scheduling (SPS)-configured Voice over Long Term Evolution (VoLTE) with Connected State Discontinuous Reception (C-DRX) are provided. The apparatus may be a user equipment (UE). The UE receives a packet when the UE is in a persistent scheduling mode. The UE transmits a negative-acknowledgement (NACK) message when the packet is not successfully decoded. The UE refrains from transmitting an acknowledgement (ACK) message when the packet is successfully decoded. The UE may enter a power save state immediately after the packet is successfully decoded. The packet may be addressed to the UE in a unicast message. The packet may be received during an on-duration of a C-DRX cycle. The packet my include VoLTE downlink (DL) traffic. The packet may be received on a physical downlink shared channel (PDSCH).
