    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 method for a communication apparatus to align a frame boundary with a cell. A first time at which a predetermined synchronization signal is supposed to be received is determined after knowing a timing of the cell. The predetermined synchronization signal is a primary synchronization signal or a secondary synchronization signal. A second time at which the predetermined synchronization signal is actually received is determined. A first offset between the first time and the second time is determined. A timing of a local time base utilized by the communication apparatus according to the first offset is adjusted such that a frame boundary of the local time base and a frame boundary of the cell are aligned.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The configuration specifies a bundle size N. Modulation symbols in N consecutive PRBs are precoded with a same precoder. The UE determines whether a precoding condition is true. The precoding condition is that modulation symbols in a first set of resources and a second set of resources are precoded with a same precoder. Each set of the first set of resources and the second set of resources contains N PRBs. When the precoding condition is met: the UE measures reference signals in the second set of resources; the UE determines a channel condition of the first set of resources in consideration of the measurements of the reference signals in the second set of resources.

    Abstract: A method for handling radio link monitoring (RLM) includes: receiving downlink (DL) data from a network device; performing a first measurement according to the DL data, to generate a first measurement result of the DL data; comparing the first measurement result and a first threshold, to determine a first indication; comparing the first measurement result and a second threshold, to determine a second indication; and determining whether a radio link failure (RLF) occurs according to at least one of the first indication and the second indication.
