Universal channel reservation signal for medium sharing

A method of wireless communication, comprising:

• identifying, by a wireless communication device of a first radio access technology (RAT), a transmission opportunity (TXOP) in a spectrum shared by the first RAT and a second RAT;
• determining, by the wireless communication device, whether the TXOP includes a first TXOP duration or a second TXOP duration that is different from the first TXOP duration;
• selecting, based on the determination, at least one of transmitting a first channel reservation signal associated with the first TXOP duration or transmitting a second channel reservation signal associated with the second TXOP duration;
• and
• transmitting, by the wireless communication device based on the selecting, at least one of:
• the first channel reservation signal including a first repeating waveform sequence to indicate the first TXOP duration;
• or
• the second channel reservation signal including a second repeating waveform sequence to indicate the second TXOP duration.

An apparatus comprising:

• a transceiver configured to detect a channel reservation signal of a second radio access technology (RAT) in a spectrum shared by a first RAT and the second RAT, wherein the apparatus is associated with the first RAT;
• and
• a processor configured to:
• determine, based on a repeating waveform sequence of the channel reservation signal, whether the channel reservation signal indicates a first transmission opportunity (TXOP) duration or a second TXOP duration that is different from the first TXOP duration;
• and
• carry out, based on the determination, at least one of:
• performing a backoff when the channel reservation signal indicates the first TXOP duration;
• or
• continuing to monitor the spectrum when the channel reservation signal indicates the second TXOP duration.

An apparatus comprising:

• a transceiver;
• and
• a processor configured to:
• identify a transmission opportunity (TXOP) in a spectrum shared by a first radio access technology (RAT) and a second RAT, wherein the apparatus is associated with the first RAT;
• determine whether the TXOP includes a first TXOP duration or a second TXOP duration that is different from the first TXOP duration;
• select, based on the determination, at least one of configuring the transceiver to transmit a first channel reservation signal associated with the first TXOP duration or configuring the transceiver to transmit a second channel reservation signal associated with the second TXOP duration;
• and
• cause the transceiver to transmit, based on the selecting, at least one of:
• the first channel reservation signal including a first repeating waveform sequence to indicate the first TXOP duration;
• or
• the second channel reservation signal including a second repeating waveform sequence to indicate the second TXOP duration.
