Abstract
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.

6. A method operable with a user equipment (UE) operating in a radio frequency (RF) band comprising a conflicting wireless technology, the method comprising:
-
processing an ID assigned by an eNodeB; transmitting a scheduling request to the eNodeB for uplink (UL) data from the UE; processing a time and frequency grant from the eNodeB for the UE to transmit the UL data; waiting until the granted time and frequency are clear of another wireless system employing a different wireless technology operating in the RF band; and when the granted time and frequency are clear, transmitting the UL data to the eNodeB.

11. An eNodeB operating in a radio frequency (RF) band comprising a conflicting wireless technology, the eNodeB comprising:
-
a processor operable to assign an ID to a user equipment (UE) operating in the RF band, to process a scheduling request for uplink (UL) data from the UE, to grant a time and a frequency for the UE to transmit the UL data, and to wait until the UE performs a Listen Before Talk (LBT) operation to determine whether the granted time and frequency are occupied by another wireless system employing a different wireless technology; and an interface operable to transmit the ID to the UE to reserve the granted time and frequency when unoccupied by the other wireless system, and to receive the UL data from the UE on the granted time and frequency. - View Dependent Claims (12, 13, 14, 15)
