Abstract: Various solutions for handling synchronization signal block with respect to user equipment (UE) and network apparatus in mobile communications are described. A UE may receive a synchronization signal block (SS block) from a network apparatus. The UE may detect a transmission beam of the network apparatus according to the SS block. The SS block may comprise a first synchronization signal, a second synchronization signal and a reference signal for detecting the transmission beam. The first synchronization signal may be a primary synchronization signal (PSS), the second synchronization signal may be a secondary synchronization signal (SSS), and the reference signal may be a demodulation reference signal (DMRS). The SS block may further comprise a broadcast channel and wherein the DMRS is used for demodulation of the broadcast channel.
