First Claim
Patent Images
1. A method of wireless communication, comprising:
- identifying a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic and a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic, wherein the first subband and the second subband are different; and
reserving the first subband for a first duration of time for a plurality of wireless devices, the reservation based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

Abstract
A wireless device may identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic. The wireless device may identify a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic. The first subband and the second subband may be different. The wireless device may reserve the first subband for a first duration of time for a plurality of wireless devices. The reservation may be based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

15. An apparatus for wireless communication, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to; identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic and a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic, wherein the first subband and the second subband are different; and reserve the first subband for a first duration of time for a plurality of wireless devices, the reservation based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
