Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: 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.
