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

In some examples, the emergency data transmission management module 1435 may include an emergency data coordination module 1440 and/or an LBT yielding parameter adjustment module 1445. In some examples, the emergency data coordination module 1440 may be used to determine whether at least one other node associated with one other operator in the deployment of operators has emergency data to transmit over the unlicensed radio frequency spectrum band. In some examples, determining that a node associated with another operator in the deployment of operators has emergency data to transmit over the unlicensed radio frequency spectrum band may include receiving a signal from a node associated with another operator. The signal received from the node associated with another operator may include an indication that the node associated with another operator has emergency data to transmit.
