Synchronization for wideband coverage enhancement

A method for wireless communication, comprising:

• generating, by a base station, a secondary synchronization signal (SSS) based at least in part on a cell identifier group associated with the base station;
• and
• transmitting, by the base station, the SSS and a primary synchronization signal (PSS) in a first subframe of a frame,
• wherein, in the first subframe, the SSS is transmitted in a symbol of the first subframe that is after a symbol of the first subframe in which the PSS is transmitted, and after a set of symbols of the first subframe in which a set of other synchronization signals is transmitted, and
• wherein, in a second subframe of the frame, the SSS is transmitted in a symbol of the second subframe that is before a symbol of the second subframe in which the PSS is transmitted.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a first subframe of a frame,
• wherein, in the first subframe, the SSS is received in a symbol of the first subframe that is after a symbol of the first subframe in which the PSS is received, and after a set of symbols of the first subframe in which a set of other synchronization signals is received, and
• wherein, in a second subframe of the frame, the SSS is received in a symbol of the second subframe that is before a symbol of the second subframe in which the PSS is received;
• and
• synchronize the apparatus with a base station based at least in part on the PSS and the SSS received in the first subframe.
