Aspects described herein generally relate to communication according to an Automated Frequency Coordination (AFC) allocation scheme.
A wireless communication frequency band, e.g., a 6 Gigahertz (GHz) band, may be utilized for communication by incumbent radios. Other devices, e.g., WiFi radios, may be required to honor the incumbent radios, when using the wireless communication frequency band. For example, a transmission power of non-incumbent radios, e.g., WiFi radios, may be restricted, for example, to ensure that any interference from the non-incumbent radios to the incumbent radios will be low enough, e.g., 6 decibel (dB) below received incumbent signal power.
For simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity of presentation. Furthermore, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. The figures are listed below.

In some demonstrative aspects, co-located access point AP set 131 may include a plurality of AP STAs 133, e.g., including AP STAs 135, 137 and/or 139. In some aspects, as shown in
In some demonstrative aspects, for example, the one or more radios 114 may include, for example, a radio for communication by AP STA 135 over a first wireless communication frequency channel, e.g., a first channel in the 6 GHz band, as described below.
In some demonstrative aspects, for example, the one or more radios 114 may include, for example, a radio for communication by AP STA 137 over a second wireless communication frequency channel, e.g., a second channel in the 6 GHz band, as described below.
In some demonstrative aspects, for example, the one or more radios 114 may include, for example, a radio for communication by AP STA 139 over a third wireless communication frequency channel, e.g., a third channel in the 6 GHz band, as described below.
In some demonstrative aspects, the radios 114 utilized by AP STAs 133 may be implemented using separate radios. In other aspects, the radios 114 utilized by AP STAs 133 may be implemented by one or more shared and/or common radios and/or radio components.
In some demonstrative aspects, controller 124 may be configured to control one or more operations and/or functionalities of device 102 for communication over a wireless communication frequency band, e.g., the 6 GHz band, which may be utilized for communication by incumbent radios. For example, device 102 may be required to honor the incumbent radios, when using the wireless communication frequency band.
In some demonstrative aspects, for example, controller 124 may be configured to restrict a transmission power of non-incumbent devices, e.g., device 140, which may communicate with device 102. For example, the transmission of the non-incumbent devices may be restricted to ensure that any interference from the non-incumbent devices to the incumbent radios will be low enough, e.g., 6 decibel (dB) below received incumbent signal power.
In some demonstrative aspects, controller 124 may be configured to control one or more operations and/or functionalities of device 102 according to one ore more location-based regulations, which may be set, for example, by a regulatory organization, e.g., the Federal Communications Commission (FCC) in the United States, or any other regulatory organization in other countries.
In some demonstrative aspects, controller 124 may be configured to control one or more communications of device 102 and/or device 140, for example, based on an allocation of one or more allowed channels and/or bandwidths, e.g., which may be assigned by the regulatory organization.
In some demonstrative aspects, controller 124 may be configured to cause device 102 to instruct one or more client STAs, e.g., device 140, to set and/or restrict a transmission power and/or any other parameter, for communication over a channel in the 6 GHz band, e.g., as described below.
In some demonstrative aspects, controller 124 may be configured to set and/or restrict one or more parameters for communication by devices 102 and/or 140, for example, based on one or more assignments of allowed resources. For example, the allowed resources may define one or more allowed channels and/or bandwidths for communication, and/or one or more restrictions, e.g., allowed transmission power, for communication over the allowed channels and/or bandwidths.
For example, the assignments of allowed resources may be location-dependent, and may depend, for example, on a known location of devices 102 and/or 140. For example, the assignments of allowed resources may take into consideration both the AP and client STA positions, for example, as interference to the incumbent devices may be the result of transmissions by either the AP or the client STA. In one example, knowledge of a better accuracy of a location of an AP, e.g., device 102, and a client STA, e.g., device 140, may allow more possibilities for channel and/or bandwidth availability.
In some demonstrative aspects, controller 124 may be configured to set and/or restrict one or more parameters for communication by devices 102 and/or 140, for example, according to an Automated Frequency Coordination (AFC) allocation scheme, e.g., as described below.
In one example, the AFC allocation scheme may be configured according to an AFC reference incumbent protection methodology, which may use link budget analyses to ensure that a Fixed Service (FS) received interference-to-noise power ratio (I/N) resulting from a Radio LAN (RLAN) device does not exceed a single-entry interference protection criteria (IPC) specified in terms of an I/N threshold.
In some demonstrative aspects, controller 124 may be configured to identify an AFC assignment of allowed resources, e.g., including assignment of allowed channel/BW and/or transmit power, for example, based on one or more messages from a server, e.g., a trusted cloud server, and/or from any other source.
In some demonstrative aspects, the AFC assignment for an AP device, e.g., device 102, may be based, for example, on a report from the AP, which may include, for example, a location report of a location of the AP, and information relating to a location of the client STA. For example, the information relating to a location of the client STA may be provided in the form of an uncertainty estimation of location of the client STA.
In some demonstrative aspects, there may be a need to provide a technical solution for efficient and/or accurate utilization of the AFC assignments, e.g., as described below.
For example, the AFC assignments may be provided to the AP device with respect to a relatively extended period of time, for example, a period of 24 hours, or longer periods, e.g., periods of about a month.
However, as client STAs may be mobile in nature, there may be a very high uncertainty level with respect to the estimated location of a client STA, for example, if a location of the client STA is not continuously measured.
In such a situation, the AP may be required to use a most stringent, e.g., limiting, AFC assignment, for example, in order to ensure that the regulatory restrictions are met, for example, if the accurate location of the client STA cannot be determined.
For example, the AP may be required to always assume a worst scenario regarding the location of the client STA, e.g., by always assuming that the client STA is at a farthest range from the AP.
For example, in this case, the AP may be restricted to using an AFC assignment, which only takes into consideration the location of the AP and the maximal transmit power. Such an AFC assignment may be very limiting and inefficient.
In one example, it may be insufficient to have the AP determine the AFC assignment with respect to a single client STA location, as AFC assignments may be for relatively long durations, e.g., between 24 hours and 30 days or any other period. Accordingly, due to the mobile nature of the client STAs, it may not be feasible to account for changes in the locations of individual client STAs, for example, if the AP uses a same operating channel for all client STAs served by the AP.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control the plurality of APs 133 of co-located AP set 131 to communicate over a respective plurality of wireless communication channels in the 6 GHz frequency band, for example, according to an AFC allocation scheme, e.g., as described below.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control the plurality of APs 133 of co-located AP set 131 to operate as multiple logical independent APs, for example, such that each AP of APs 133 may operate over its own operational channel.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control the plurality of APs 133 to operate according to the AFC allocation scheme, for example, by configuring the plurality of APs 133 to use a respective plurality of AFC allocated channels, e.g., as described below. For example, an AP, e.g., each AP, of co-located AP set 131, may be configured to use a separate AFC allocated channel, e.g., as described below.
In some demonstrative aspects, the plurality of AFC allocated channels may be configured, for example, with respect to a same AP physical location, for example, corresponding to the location of device 102, e.g., as described below.
In some demonstrative aspects, the plurality of AFC allocated channels may be configured, for example, with respect to a plurality of different location uncertainties and/or different ranges to client STAs, e.g., as described below.
For example, APs 133, e.g., each of AP 133, of the co-located AP set 131 may report a same location with different uncertainty values.
For example, an uncertainty measurement may be used to account for the dynamically measured distance from the AP device 102 to the client STAs.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control an AP of APs 133, which is in communication with a client STA, e.g., device 140, to request from the client STA to continuously report its location and/or its range from device 102, e.g., as described below.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control the AP, which is in communication with the client STA, to request from the client STA to continuously report its location and/or its range from device 102, for example, based on range measurements of Fine Time Measurement (FTM) protocol, e.g., as described below.
In other aspects, the location and/or range of the client STA may be measured and/or monitored based on any other range and/or location measurement mechanism and/or protocol.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control one or more APs of the co-located AP set 131 to dynamically direct client STAs, e.g., device 140, to use an appropriate channel, for example, based on the monitored location and/or range of the client STAs, e.g., as described below.
In some demonstrative aspects, controller 124 may be configured to cause, trigger and/or control one or more APs of the co-located AP set 131 to dynamically assign an operating channel to c client STA, e.g., device 140, for example, based on the location of the client STA, for example, such that the client STA is within the coverage area of the allowed AFC channel, e.g., as described below.

In some demonstrative aspects, controller 124 may be configured to trigger, cause, instruct and/or control device 102 to instruct the STA, e.g., device 140, to communicate with the co-located AP set 131 over an assigned wireless communication channel of the plurality of wireless communication channels, e.g., as described below.
In some demonstrative aspects, the assigned wireless communication channel may have an AFC allocation corresponding to a coverage area, which covers the estimated distance between the STA, e.g., device 140, and device 102, e.g., as described below.
In some demonstrative aspects, controller 124 may be configured to trigger, cause, instruct and/or control device 102 to instruct the STA, e.g., device 140, to switch between communication channels of the plurality of wireless communication channels for communication with the co-located AP set 131, for example, based on an identified movement of the STA between the coverage areas, e.g., as described below. For example, controller 124 may be configured to trigger, cause, instruct and/or control co-located APs 133 to command the client STA 140 to move, e.g., together with its entire data, signaling and STA state, from one co-located AP operating channel of one of APs 133 to another co-located AP operating channel of another one of APs 133.

In some demonstrative aspects, the first coverage area may be defined according to a first maximal distance from the device 102, and/or the second coverage area may be defined according to a second maximal distance from the device 102, e.g., different from the first maximal distance from device 102.
