摘要

Techniques are described for wireless communication. A first method includes determining that a first node associated with a first operator in a deployment of operators has emergency data to transmit over an unlicensed radio frequency spectrum band and transmitting, by the first node, a signal over the unlicensed radio frequency spectrum band. The signal may indicate that the first node has emergency data to transmit. A second method includes receiving, at a first base station associated with a first operator in a deployment of operators, an uplink transmission from a user equipment (UE) indicating that the UE has emergency uplink data to transmit over an unlicensed radio frequency spectrum band and transmitting, by the first base station, an indication to a second base station that the UE has emergency uplink data to transmit over the unlicensed radio frequency spectrum band.

說明書

At block 2220, the method 2200 may include adjusting a CCA opportunity of the first node in response to the determination that the first node has emergency data to transmit. The operation(s) at block 2220 may be performed using the wireless communication management module 1220, 1320, 1520, 1760, and/or 1860 described with reference to FIGS. 12, 13, 15, 17, and/or 18, the emergency data transmission management module 1235, 1335, and/or 1535 described with reference to FIGS. 12, 13, and/or 15, and/or the CCA opportunity adjustment module 1545 described with reference to FIG. 15.

At block 2225, the method 2200 may include determining whether to adjust a CCA opportunity of the first node in response to the determination that the first node has emergency data to transmit, and based on a total number of operators in the deployment of operators that have emergency data to transmit over the unlicensed radio frequency spectrum band. When it is determined at block 2225 to adjust the CCA opportunity of the first node, the CCA opportunity of the first node may be adjusted at block 2225. The operation(s) at block 2225 may be performed using the wireless communication management module 1220, 1320, 1520, 1760, and/or 1860 described with reference to FIGS. 12, 13, 15, 17, and/or 18, the emergency data transmission management module 1235, 1335, and/or 1535 described with reference to FIGS. 12, 13, and/or 15, and/or the CCA opportunity adjustment module 1545 described with reference to FIG. 15.
