Patent ID: 10104629

Abstract:
Techniques described herein may be used to more efficiently use subcarriers allocated to a narrowband channel of a wireless telecommunications network. For example, a base station may identify a middle subcarrier of the narrowband channel and partition the middle subcarrier into additional subcarriers. The additional subcarriers may include a direct circuit (DC) subcarrier occupying a middle bandwidth of the middle subcarrier, and a synchronization subcarrier and a paging subcarrier on either side of the DC subcarrier. The synchronization subcarrier may be dedicated exclusively to communicating synchronization information, and the paging subcarrier may be dedicated exclusively to communicating paging information. The synchronization information may include a preamble signal, a Primary Synchronization Signal (PSS), and a Secondary Synchronization Signal (SSS) that are repeated over consecutive frames. The paging information may include paging codes that devices may passively listen for in order to be paged by the base station.
