Methods, systems, and apparatuses are described for wireless communications, in which transmission of common information to two or more receivers over unlicensed spectrum may be provided. The common information may be transmitted over a number (e.g., a set) of different carrier frequencies of the unlicensed spectrum. A staggering pattern may be employed to transmit all or a part of the common information across each of the carrier frequencies in the set of carrier frequencies. The detection of the information on one of the carrier frequencies may provide information that may be used to derive the staggering pattern. The duration of the common information transmission on each of the carrier frequencies may be selected such that a clear channel assessment (CCA) to determine availability of the unlicensed spectrum is not required.
