Systems and methods presented herein provide for channel reservation for a wireless telephony system operating in an RF band with a wireless system comprising a conflicting wireless technology. One method is operable with an eNodeB. The method includes assigning an ID (e.g., a PN sequence) to a user equipment (UE) operating in the RF band, processing a scheduling request for uplink (UL) data from the UE, and granting a time and a frequency for the UE to transmit the UL data. The method also includes waiting until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency is occupied by another wireless system employing a different wireless technology. The method also includes transmitting the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and processing the UL data from the UE.
