Methods and systems are disclosed for processing control messages transmitted from multiple base stations and received at a mobile device. The mobile device may have wireless access using LTE or NR carrier aggregation and may be enabled to send uplink communication to multiple base stations. In a particular implementation, transmission power control (TPC) parameters transmitted by the multiple base stations and received at the mobile device may be processed to determine one or more aspects of motion of the mobile device such as a direction of motion, distance of motion and/or a location of the mobile device.
