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(shuō)明書(shū)

At block 2105, the method 2100 may include 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. The unlicensed radio frequency spectrum band may be a radio frequency spectrum band for which apparatuses may need to contend for access because the radio frequency spectrum band is available, at least in part, for unlicensed use (e.g., Wi-Fi use and/or unlicensed LTE/LTE-A use). The first node may in some examples include a base station and may in some examples include a UE. In some examples, the base station or UE may be an LTE/LTE-A-compatible base station or UE. The operation(s) at block 2105 may be performed using the wireless communication management module 1220, 1320, 1420, 1760, and/or 1860 described with reference to FIGS. 12, 13, 14, 17, and/or 18, and/or the emergency data transmission management module 1235, 1335, and/or 1435 described with reference to FIGS. 12, 13, and/or 14.
