Methods, systems, apparatus and computer program products are provided to improve synchronization of information units communicated in a wireless communication system. Timing misalignment in the transmission of adjacent information units can produce gaps or overlaps in the transmitted information. In a long-term evolution (LTE) wireless communication system, such gaps and overlaps can be eliminated or reduced by adjusting the lengths of a cyclic prefix portion of one or more transmitted symbols. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.
