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.

Tracking reference signal and framework thereof in mobile communications

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, and uses broadcast information for performing radio link monitoring, cell measurement, or channel estimation with the service network.

Broadcast information-assisted communication methods and apparatuses using the same

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.

Apparatuses and methods for physical broadcast channel (PBCH) assisted synchronization during a discontinuous reception (DRX) operation

A channel estimation method estimates a data channel of a data resource element of a physical resource block in a time-frequency domain. The method includes: utilizing a detection circuit to perform a first physical resource block bundling detection in a first direction of the time-frequency domain to detect if at least one neighboring physical resource block is allowed to be bundled with the physical resource block, and accordingly generating a first physical resource block bundling detection result; determining a physical resource block processing range according to at least the first physical resource block bundling detection result, wherein at least the physical resource block is included in the physical resource block processing range; obtaining a plurality of pilot channels for pilot resource elements in the physical resource block processing range; and estimating the data channel of the data resource element according to the pilot channels.
