message of the one or more channel status messages is configured to indicate a channel associated with a neighboring device of the network device (the other access points may include a neighboring access point that is within wireless communication range of the access point [0054]) and a channel metric associated with the channel (During operation, the access point may receive, associated with other access points, information (operation 210) specifying one or more communication-performance metrics associated with a shared band of frequencies. For example, the information may be received in one or more packets or frames. Note that the one or more communication-performance metrics may include one or more RSSI, SNR, etc. measurements or values. In some embodiments, the one or more communication-performance metrics may include associated channel information and/or an identifier of a given access point in the other access points that performed measurements that determined an instance of the one or more communication-performance metrics [0053]-[0055]);

In some embodiments, the NB packets (e.g., used for transmitting NB_POLL, NB_RSP, and/or NB_DATA) use different channels in different ranging rounds. For example, as depicted in FIG. 46, ranging round X 4602 may use channel A 4606, and a subsequent ranging round Y 4604 may use channel B 4608 [0213]).
Therefore, it would have been obvious to one of ordinary skill in art before the effective filing date of the claimed invention to modify Matta execute a ranging round by utilizing the selected target channel, as taught by Hammer for the purpose of providing techniques for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency (abstract).
Regarding claim 6, the combination of Matta and Hammer discloses everything claimed as applied above (see claim 1), further Matta discloses, wherein the channel metric corresponds to a Received Signal Strength Indicator (RSSI) value determined by the neighboring device on the channel for a source device (the one or more communication-performance metrics may include RSSI, SNR, etc. measurements of received wireless signals associated with one or more of access points 116 in different channels in the shared band of frequencies [0048]; [0053]-[0054]).

The BLE then converts that time into its own time domain (denoted as f(Tx)), possibly in reference to the advertisement packet in which it is transmitted. Once the Ranging Round X 4010 completes, the NB-UWB entity communicates the start time (Tx+1) of the next Ranging Round X+1 4012 to the BLE entity. The BLE entity sends two advertisement packets 4014a-b referencing to the same Ranging Round X+1 4012, since that is the next ranging round in both the cases [0202]).

For example, as depicted in FIG. 46, ranging round X 4602 may use channel A 4606, and a subsequent ranging round Y 4604 may use channel B 4608 [0213]).

For example, as depicted in FIG. 46, ranging round X 4602 may use channel A 4606, and a subsequent ranging round Y 4604 may use channel B 4608 [0213]).
