A user equipment (UE) may receive a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) in a subframe. In one example, the SSS may be received in a symbol that is after a symbol in which the PSS is received, and after a set of symbols in which a set of other synchronization signals is received. In another example, the PSS may be received in each of a first plurality of consecutive symbols, and the SSS may be received in each of a second plurality of consecutive symbols, wherein the second plurality of consecutive symbols is after the first plurality of consecutive symbols within the subframe. The UE may synchronize with a base station based at least in part on the PSS and the SSS. Numerous other aspects are provided.
