Method, system and apparatus for low power mode cooperative synchronization

Abstract

Some embodiments of the present disclosure relate to the use of chirp signals in synchronization procedures in wireless communication systems. The synchronization chirp signal is received and processed by a user equipment (UE) in a low power mode for synchronization purposes. The use of the synchronization chirp signal allows for low-complexity processing in the radio frequency (RF) analog domain. Processing in the RF analog domain is known to reduce power consumption relative to processing in the baseband digital domain. Reducing beam sweeping at the UE can also be shown to reduce power consumption and processing complexity at the UE. After the UE interacts with a device transmitting a synchronization signal, the device transmitting the synchronization signal can report measurements to the network. As a result of receiving the measurement report, the network can estimate the timing advance of the UE.
