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 an eighth set of illustrative examples, a computer program product for communication by a wireless communication apparatus in a wireless communication system is described. In one example, the computer program product may include a non-transitory computer-readable medium storing instructions executable by a processor to cause the wireless communication apparatus to receive, at a first base station associated with a first operator in a deployment of operators, an uplink transmission from a UE indicating that the UE has emergency uplink data to transmit over an unlicensed radio frequency spectrum band. The instructions may also be executable by the processor to cause the wireless communication apparatus to cause the first base station to transmit an indication to a second base station that the UE has emergency uplink data to transmit over the unlicensed radio frequency spectrum band. In some examples, the instructions may also be executable by the processor to cause the wireless communication apparatus to implement one or more aspects of the method for wireless communication described above with respect to the fifth set of illustrative examples.
