Techniques for managing a plurality of radio access technologies accessing a shared radio frequency spectrum band
First Claim
1. A method for wireless communication, comprising:
- sensing an indication of first radio access technology (RAT) communications occupying a shared radio frequency spectrum band;
configuring, in response to the sensing, at least one parameter of a second RAT used by a device to contend for access to the shared radio frequency spectrum band; and
configuring a range of numbers from which a random number is selected, wherein the random number determines a number of clear channel assessment (CCA) slots over which the device performs at least one of a plurality of extended CCA procedures.

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.
