Abstract
Methods, systems, and devices for wireless communications are described. A transmitter may include an interference avoidance preamble in a wireless transmission. The interference avoidance preamble may identify resources for transmitting an interference avoidance request associated with the wireless transmission. A receiver may experience interference between the wireless transmission and another wireless transmission, and the receiver may transmit the interference avoidance request using the resources identified in the interference avoidance preamble. The transmitter may receive the interference avoidance request and, in response, may enable an interference avoidance mechanism, for example, a listen before talk (LBT) procedure, a frequency-division multiplexing (FDM) scheme, a time-division multiplexing (TDM) scheme, a spatial multiplexing scheme, or a combination.
