Abstract: Techniques are described for wireless communication. A first method includes sensing an indication of first radio access technology (RAT) communications occupying a shared radio frequency spectrum band; and configuring, in response to the sensing, at least one parameter of a second RAT used by a device to contend for access to the band. A second method includes randomly selecting a number from a range of numbers extending between a lower bound and an upper bound; contending for access to a shared radio frequency spectrum band by performing an extended clear channel assessment (ECCA) procedure over a plurality of CCA slots, the plurality of CCA slots including a first number of CCA slots equal to the upper bound; and winning contention for access to the band after determining, while performing the ECCA procedure, that the band is available for a second number of CCA slots equal to the randomly selected number.

Abstract: A method for wireless communications by a node is disclosed, comprising: determining whether a supervising node coexists with one or more neighbor supervising nodes; activating a relaxed energy detection (ED) threshold for establishing medium access suitability for an unlicensed spectrum based on a determination that the supervising node coexists with the one or more neighbor supervising nodes; and performing an access procedure for the unlicensed spectrum based on the relaxed ED threshold, being higher in value than a default ED threshold. Activating the relaxed ED threshold includes activating the relaxed ED threshold based on at least one medium access deferral not caused by the default ED threshold; and wherein the at least one medium access deferral includes a plurality of medium access deferrals, and deactivating the relaxed ED threshold based on a determination that a portion of the plurality of medium access deferrals not caused by the default ED threshold do not exceed the time deferral threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device that uses a first radio access technology (RAT) may identify a transmission timing scheme for a shared radio frequency spectrum band, the transmission timing scheme comprising a first set of time intervals allocated for transmissions using a first RAT and a second set of time intervals allocated for transmissions using a second RAT. The wireless device may transmit, during a time interval of the first set of time intervals, a channel reservation signal indicating an end time of the time interval and indicating that the wireless device uses the first RAT. The wireless device may transmit, based at least in part on the transmitted channel reservation signal, over the shared radio frequency spectrum band during at least a portion of the time interval before the end time of the time interval.
