Enhanced UE data transmission for power consumption optimization

摘要

Methods for enhanced UE data transmission for power consumption optimization are disclosed. A UE detects UE conditions and determines a UE traffic characteristic. The UE performs power consumption optimization based on the traffic characteristic. In one novel aspect, based on the UE condition, the UE determines that the traffic characteristic is low priority traffic or mobile originated only traffic. In one embodiment, the UE aligns prescheduled low priority data transmission with mobility management messages, or group multiple low priority prescheduled data transmission together. In another embodiment, the UE reduces NAS retry process upon detecting application triggered low priority traffic. In another embodiment, the UE turns off RF module until next data transmission for MO only traffic. In another novel aspect, the UE detects and sends UE conditions to the network. The network determines a UE traffic characteristic and performs power consumption optimization accordingly.

1. A method, comprising:
obtaining a set of traffic characteristics for multiple transmission procedures by a user equipment (UE) in a wireless network based on one or more predefined UE conditions, wherein each traffic characteristic indicates regular traffic or low priority traffic; identifying one or more transmission procedures as low priority traffic upon detecting at least one predefined UE conditions comprising: a transmission data size is smaller than a predefined threshold, a required bandwidth or throughput is smaller than a predefined threshold, an application ID indicating a predefined small-size data transmission, a data transmission triggered by an application, an access point name (APN) indicating small-size or low priority data transmission, a UE subscription information indicating the UE being an mobile originated (MO) only or mobile terminated (MT) only device, and a hardware status indicating power saving mode; and performing one or more corresponding procedure-based power consumption optimizations for the identified one or more low priority traffic transmission procedures while maintaining concurrent regular traffic transmission procedures, wherein each corresponding procedure-based power consumption optimization is for the specific identified low priority traffic transmission based on the corresponding traffic characteristic.
