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

The UE memory module 1820 may include RAM and/or ROM. The UE memory module 1820 may store computer-readable, computer-executable code 1825 containing instructions that are configured to, when executed, cause the UE processor module 1810 to perform various functions described herein related to wireless communication (e.g., functions relating to indicating that emergency data needs to be transmitted, transmitting emergency data, etc.). Alternatively, the code 1825 may not be directly executable by the UE processor module 1810 but be configured to cause the UE 1815 (e.g., when compiled and executed) to perform various of the functions described herein.

The UE processor module 1810 may include an intelligent hardware device, e.g., a CPU, a microcontroller, an ASIC, etc. The UE processor module 1810 may process information received through the UE transceiver module(s) 1830 and/or information to be sent to the UE transceiver module(s) 1830 for transmission through the UE antenna(s) 1840. The UE processor module 1810 may handle, alone or in connection with the UE wireless communication management module 1860, various aspects of communicating over (or managing communications over) a first radio frequency spectrum band (e.g., a radio frequency spectrum band for which apparatuses do not contend for access because the radio frequency spectrum band is licensed to particular users for particular uses, such as a licensed radio frequency spectrum band usable for LTE/LTE-A communications) and/or a second radio frequency spectrum band (e.g., 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, such as Wi-Fi use and/or unlicensed LTE/LTE-A use).
