Abstract: Techniques and examples of tracking reference signal and framework thereof in mobile communications are described. A user equipment (UE) receives, from a base station of a network, a reference signal via a communication link between the UE and the base station. The reference signal contains resource configuration with respect to tracking reference signal (TRS) configuration. The UE also receives, from the base station, a TRS burst containing a plurality of TRS symbols with one or more components of the UE configured according to the TRS configuration. The UE processes the TRS burst to perform channel estimation, synchronization, time tracking, frequency tracking, or a combination thereof.

Abstract: A mobile communication device with a Radio Frequency (RF) unit and a processing unit is provided. The RF unit transmits and receives wireless signals to and from a service network. The processing unit configures the RF unit to communicate with the service network in a DRX operation, and uses a Physical Broadcast Channel (PBCH) for synchronizing with the service network during the DRX operation.
