COMMON SYNCHRONIZATION CHANNEL DESIGN FOR NARROWBAND COMMUNICATIONS

摘要

Narrowband communications in a wireless communications system may include a common synchronization signal, such as a primary synchronization signal (PSS), secondary synchronization signal (SSS), or physical broadcast channel (PBCH). Content of the common synchronization signal may indicate a location of narrowband data transmissions in a narrowband region of a system bandwidth. The location of the narrowband region may be in-band within one or more wideband transmissions, within a guard-band bandwidth adjacent to the wideband transmissions bandwidth, or within a stand-alone bandwidth that is non-adjacent to the wideband transmissions. The common synchronization signal may be located within a predefined search frequency and may include an anchor synchronization channel present in certain resources of allocated narrowband communications resources. Narrowband data region resources may be distributed in other portions of the narrowband communications resources, and may be allocated to different users to provide transmit diversity.

主权项

1. A method for wireless communication in a system that supports narrowband transmissions in a narrowband region of a system bandwidth, comprising:
identifying anchor resources within a wideband bandwidth of one or more wideband transmissions for transmission of at least a portion of a synchronization signal comprising synchronization information for device discovery, wherein the anchor resources comprise one or more resource blocks (RBs) located at a predefined resource location within the wideband bandwidth; and transmitting at least a portion of the synchronization signal via the anchor resources.
