Intertechnology medium sharing for millimeter wave

Abstract:

Methods, systems, and devices for wireless communications are described. The method includes receiving a transmission from a first wireless device at a second wireless device, the transmission including a first coexistence preamble configured to reserve a channel of a shared radio frequency band for a first period of time, a first segment, and a second segment, where the first coexistence preamble comprises an initial channel reservation sequence and a data field indicating information about the first period of time; and transmitting, during a gap period between the first segment and the second segment, a receiver protection signal from the second wireless device, the receiver protection signal including a second coexistence preamble configured to reserve the channel of the shared radio frequency band for a second period of time associated with the second transmission segment.
