Abstract: Described is an apparatus of an Evolved Node-B (eNB) operable to communicate with a User Equipment (UE) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to initiate a Listen-Before-Talk (LBT) procedure on a bandwidth of the wireless network, the bandwidth being unlicensed spectrum. The second circuitry may be operable to generate a transmission if the LBT procedure indicates that the bandwidth is idle, the transmission comprising a Physical Random Access Channel (PRACH) preamble portion and a message portion.
