DOWNLINK SYNCHRONIZATION CHANNEL FOR THE NARROW-BAND CELLULAR IOT

摘要

To enable efficient synchronization and/or cell acquisition, systems and methods are described for broadcast of a synchronization signal in a synchronization channel. According to an aspect, a base station may generate a synchronization signal and assign the synchronization signal to be carried on a synchronization channel that is time-division multiplexed with one or more other channels (e.g., one or more other downlink channels). The synchronization channel may be a single-carrier channel and/or a wide-band channel. The base station may transmit synchronization signal (e.g., periodically broadcast) on the synchronization channel to enable a time and/or frequency synchronization. According to an aspect, the UE may acquire synchronization information based on detection of the repeating synchronization signal.

1. A method of wireless communication of a base station, the method comprising:
generating a synchronization signal for transmission in a synchronization channel, the synchronization channel spanning an entire bandwidth available for downlink transmission, the synchronization signal having at least two repetitions of a sequence; multiplexing the synchronization channel with at least one other downlink channel in at least one downlink frame; and transmitting the at least one downlink frame having the synchronization channel multiplexed with the at least one other downlink channel.
