Many environments or operational conditions create repetitive radio frequency (RF) interference conditions resulting from repetitive mechanical or electrical activity. This activity may create oscillations in the RF conditions between an MTC UE and a serving base station. Aspects of the present invention are directed to improving data efficiency and battery life by optimizing communication based on a detected periodicity of repetitive mechanical or electrical activity at the UE by monitoring the oscillations of at least one RF condition between the MTC UE and the base station, and scheduling communication between the UE and the network during periods associated with favorable radio conditions.

Scheduling in repetitive RF environments

The disclosure provides for a user equipment (UE) detecting an indication of an application-specific latency reduction triggering condition that may trigger switching of a communication state of the UE. For example, the UE may be in an initial state. The UE may transition into a different state that is associated with lower latency for data transfer. In an aspect, the UE may trigger the indication for latency reduction even when the network-configured criteria for the indication has not yet been met. The UE may trigger an application-specific latency reduction triggering condition during the startup of an application, which triggers a resource request message even before the network-configured threshold value for generating such resource request messages is satisfied. The resource request message may cause the network to command the UE to transition to a state that has a latency less than that in the current state.
