Synchronous clear to send signaling

An apparatus for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• identify a wireless channel allocated for a data transmission to be transmitted using a first radio access technology (RAT) during a first time period;
• receive a configuration parameter indicating whether to transmit, using a second RAT, a message that indicates that the data transmission is to occur via the first RAT and during the first time period;
• transmit the message using the second RAT, the second RAT being a wireless local area network (WLAN) and being different from the first RAT, the message being transmitted during a second time period designated for second RAT transmissions by one or more user equipments (UEs) and based at least in part on the configuration parameter;
• and
• transmit or receiving the data transmission over the wireless channel during the first time period using the first RAT.

An apparatus for wireless communication, comprising:

• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive a message indicating that a data transmission is to occur over a wireless channel during a first time period and transmitted using a first radio access technology (RAT) from multiple user equipments (UEs) as part of a synchronous transmission, the message being received using a second RAT that is a wireless local area network (WLAN), the first RAT being different from the second RAT, the message being transmitted during a second time period designated for transmissions of messages using the second RAT by the multiple UEs;
• and
• refrain from communicating over the wireless channel during the first time period based at least in part on receiving the message.
