and an interface configured to output the first frame for transmission to the wireless node via at least one of a plurality of channels that form the bonded channel; wherein the processing system is further configured to generate at least one request to send (RTS) frame, and the interface is further configured to output the at least one RTS frame for transmission to the wireless node via the bonded channel. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the first frame is output for transmission to the wireless node via a single channel of the plurality of channels. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the at least one RTS frame comprises a separate RTS frame output for transmission on each of the plurality of channels. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the first frame comprises a management frame. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein: the processing system is further configured to select a type of the first frame to signal the wireless node to adjust its receive antenna configuration; and generation of the first frame is based on the selected type. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the first frame has at least one bit that signals the wireless node to adjust its receive antenna configuration. ### Claim 7 An apparatus for wireless communications, comprising: an interface configured to obtain a first frame via at least one of a plurality of channels that form a bonded channel; and a processing system configured to place the apparatus in a first receiver mode associated with the bonded channel after obtaining the first frame; wherein the interface is also configured to obtain at least one request to send (RTS) frame via the bonded channel while the apparatus is in the first receiver mode. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the first receiver mode comprises a directional receiver mode in which the apparatus adjusts a receive antenna configuration to enhance reception from a particular direction. ### Claim 9 (depends on 7) The apparatus of claim 7, wherein the first frame is obtained via a single channel of the plurality of channels. ### Claim 10 (depends on 7) The apparatus of claim 7, wherein: the at least one RTS frame comprises a separate RTS frame obtained via each of the plurality of channels; and the processing system is configured to combine signals related to the separate RTS frames and to perform detection of the at least one RTS frame based on the combined signals. ### Claim 11 (depends on 7) The apparatus of claim 7, wherein the processing system is configured to place the apparatus in the first receiver mode based on a type of the first frame. ### Claim 12 (depends on 7) The apparatus of claim 7, wherein the processing system is configured to place the apparatus in the first receiver mode based on at least one bit in the first frame. ### Claim 13 (depends on 7) The apparatus of claim 7, wherein the processing system is further configured to adjust a receive antenna configuration of the apparatus after obtaining the at least one RTS frame. ### Claim 14 An apparatus for wireless communications, comprising: an interface configured to obtain, from a wireless node, a separate request to send (RTS) frame via each of a plurality of channels that form a bonded channel; and a processing system configured to combine signals related to the separate RTS frames obtained via the plurality of channels that comprises generating log likelihood ratios (LLRs) based on signals related to each of the RTS frames and combining the LLRs; wherein the processing system is further configured to perform RTS frame detection based on the combined signals; and wherein the processing system is further configured to process a detected RTS frame to determine whether the apparatus is an intended recipient of the detected RTS frame, to generate a clear to send (CTS) frame if the apparatus is the intended recipient, or to avoid causing transmissions on the bonded channel for a duration if the apparatus is not the intended recipient. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein each separate RTS frame is a duplicate of each other. ### Claim 16 (depends on 14) The apparatus of claim 14, wherein the processing system is further configured to perform a channel estimation for each of the plurality of channels and to perform the RTS frame detection based on the channel estimation for each of the plurality of channels. ### Claim 17 (depends on 14) The apparatus of claim 14, wherein: the processing system is further configured to perform at least one of time-tracking, phase tracking, or frequency tracking jointly for more than one of the plurality of channels; and the RTS frame detection is performed based on the time-tracking, phase tracking, or frequency tracking. ### Claim 18 (depends on 14) The apparatus of claim 14, wherein the processing system is further configured to adjust a receive antenna configuration of the apparatus after obtaining the separate RTS frames.
