Abstract:
Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a processor communicatively coupled to the transceiver. The processor is configured to determine a reference signal sequence that comprises a primary synchronization signal (PSS) sequence and a secondary synchronization signal (SSS) sequence of a target cell. The processor is further configured to receive a signal sequence from the target cell and calculate an overall correlation value based on the reference signal sequence and the received signal sequence. The processor is further configured to determine that the overall correlation value is above a threshold and detect a synchronization signal block (SSB) of the target cell based on the received signal sequence. Finally, the processor is configured to establish a wireless connection with the target cell based on the SSB.
