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.

where GroupID is a “deployment group-id” assigned to the base station 105, and t is the LBT frame number corresponding to a gating interval or frame for which the DCCA 1140-a is performed. However, when a base station 105 has emergency data to transmit, an alternate mapping-function may be used to choose which of the seven possible DCCA opportunities to use to perform a DCCA 1140-b. In some examples, the mapping-function may cause each of the base stations 105 having emergency data to transmit to perform a DCCA 1140-b concurrently, at an earliest DCCA opportunity. In some examples, emergency data from all operators subject to an emergency data transmission agreement may be transmitted during the LBT frame 1115 upon any one of the operators gaining access to the LBT frame 1115, and non-emergency data may be transmitted during the LBT frame 1115 for a single one of the operators (i.e., the operator that performs a successful DCCA 1140-a or 1140-b). In some examples, the operators subject to the emergency data transmission agreement may form a joint MBSFN. At least a portion of the emergency data to be transmitted by each operator may be transmitted as part of the LTE/LTE-A based waveform 1147.
