Methods and apparatus for redundant waveform protection in a mixed wireless communication system

An apparatus configured to communicate over a wireless medium, comprising:

• a processor configured to:
• generate a first communication reserving access to the wireless medium during a first time period;
• detect, prior to the first time period, an interfering WLAN transmission that will result in its transmitter and recipients not detecting the first communication;
• and
• generate, for transmission after the WLAN transmission, a second communication reserving access to the wireless medium during a second time period at least partially overlapping the first;
• a transmitter configured to transmit the first and second communications;
• and
• a transmitter or receiver configured to transmit or receive a long term evolution unlicensed (LTE-U) transmission during the first time period.

An apparatus for communication over a wireless medium, comprising:

• means for transmitting a first communication reserving access to the wireless medium during a first time period;
• means for transmitting or receiving a long term evolution unlicensed (LTE-U) transmission during the first time period;
• means for detecting, prior to the first time period, an interfering WLAN transmission that will result in its transmitter and recipients not detecting the first communication;
• and
• means for transmitting, after the interfering WLAN transmission, a second communication reserving access to the wireless medium during a second time period at least partially overlapping the first.

A non-transitory computer-readable medium comprising code that, when executed, causes an apparatus to:

• transmit a first communication reserving access to the wireless medium during a first time period;
• transmit or receive a long term evolution unlicensed (LTE-U) transmission during the first time period;
• detect, prior to the first time period, an interfering WLAN transmission that will result in its transmitter and recipients not detecting the first communication;
• and
• transmit, after the interfering WLAN transmission, a second communication reserving access to the wireless medium during a second time period at least partially overlapping the first.
