Tracking Reference Signal And Framework Thereof In Mobile Communications

An apparatus implementable in a user equipment (UE), comprising:

• a transceiver capable of wirelessly communicating with a base station of a network;
• and
• a processor coupled to the transceiver, the processor capable of performing operations comprising:
• receiving, via the transceiver from the base station, a reference signal via a communication link between the UE and the base station, the reference signal containing resource configuration with respect to tracking reference signal (TRS) configuration;
• receiving, via the transceiver 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;
• and
• processing the TRS burst to perform channel estimation, synchronization, time tracking, frequency tracking, or a combination thereof,
• wherein the processor receives the plurality of TRS symbols of the TRS burst through a same antenna port of the UE, and
• wherein the plurality of TRS symbols occupy a same subcarrier location.
