Abstract

Methods, apparatus, and computer-readable media are described for enabling six gigahertz operation based on geolocation precision. A geographic location and an imprecision of the geographic location of an AP are determined. The geographic location and the imprecision are encoded for transmission to a remote entity. In response to the transmission of the geographic location and the imprecision, operating restrictions for the 6GHz band are received. Based on the operating restrictions, interference from the AP on an incumbent system is calculated. An available channel within the 6GHz band based on the calculated interference is determined. Data is encoded for transmission on the available channel.

PRECISION" which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002] Embodiments pertain to wireless networks and wireless communications. Some embodiments relate to wireless local area networks (WLANs) and Wi-Fi networks including networks operating in accordance with the IEEE 802, 1 1 family of standards. Some embodiments relate to IEEE

DESCRIPTION

[0015] Expanding Wi-Fi to provide additional bandwidth may include using spectrum for unlicensed use. One such area is allowing unlicensed Wi-Fi use within the 6-7GHz band (6GHz band). There are currently already systems (incumbent systems) that utilize the 6GHz band. For example, satellites use this band to communicate. Incumbents have concerns regarding the background radiation that unlicensed systems would cause. Specifically, this background radiation could impact receivers and data decoding for incumbent systems. Typical Wi-Fi deployments would likely negatively impact performance for incumbent systems. Described herein are embodiments that allow Wi-Fi deployments to operate in the 6GHz band while allowing incumbent systems to continue successful operation.

[0016] Currently in 802, 1 laf, stations (STAs) operate in lower bands, e.g., 2.4/5GHz. The unlicensed band between 6GHz and 7GHz may be open for STA operation.

[0017] Currently, 802.1 1 af has defined a protocol to allow an access point (AP) access to a database that allows the AP to determine how a STA accesses one of the lower bands. The APs with access to the database may be called geolocation database dependent (GDD) enabling STAs. A STA seeking to access a lower band may be referred to as a GDD dependent STA. A STA seeking to access the band between 6GHz and 7GHz may utilize features of the 802. 1 l af GDD protocol with enhancements to seek access to the 6GHz band. In various embodiments, a GDD process is described that allows enablement for operation of a STA at 6GHz via messaging in the lower 2.4GHz and 5 GHz bands.

In addition, a switch 103 may be provided between the WLAN FEM circuitry 104A and the BT FEM circuitry 104B to allow switching between the WLAN and BT radios according to application needs. In addition, although the antennas 101 are depicted as being respectively connected to the WLAN FEM circuitry 104A and the BT FEM circuitry 104B, embodiments include within their scope the sharing of one or more antennas as between the WLAN and BT FEMs, or the provision of more than one antenna connected to each of FEM 04 A or 104B.

[0023] In some embodiments, the front-end module circuitry 104, the radio IC circuitry 106, and baseband processing circuitry 108 may be provided on a single radio card, such as wireless radio card 102.

[0028] In some embodiments, as further shown in FIG. 1, the BT baseband circuitry 108B may be compliant with a Bluetooth (BT) connectivity standard such as Bluetooth, Bluetooth 4.0 or Bluetooth 5.0, or any other iteration of the Bluetooth Standard. In embodiments that include BT functionality as shown for example in Fig. 1, the radio architecture 100 may be configured to establish a BT synchronous connection oriented (SCO) link and/or a BT low energy (BT LE) link. In some of the embodiments that include functionality, the radio architecture 100 may be configured to establish an extended SCO (eSCO) link for BT communications, although the scope of the embodiments is not limited in this respect. In some of these embodiments that include a BT functionality, the radio architecture may be configured to engage in a BT Asynchronous Connection-Less (ACL) communications, although the scope of the embodiments is not limited in this respect. In some embodiments, as shown in FIG. 1 , the functions of a BT radio card and WLAN radio card may be combined on a single wireless radio card, such as single wireless radio card 102, although embodiments are not so limited, and include within their scope discrete WLAN and BT radio cards

[0029] In some embodiments, the radio-architecture 100 may include other radio cards, such as a cellular radio card configured for cellular (e.g., 3 GPP such as LTE, LTE- Advanced or 5G communications). [0030] In some IEEE 802.1 1 embodiments, the radio architecture 100 may be configured for communication over vario s channel bandwidths including bandwidths having center frequencies of about 900 MHz, 2.4 GHz, 5 GHz, and bandwidths of about 1 MHz, 2 MHz, 2.5 MHz, 4 MHz, 5MHz, 8 MHz, 10 MHz, 16 MHz, 20 MHz, 40MHz, 80MHz (with contiguous

bandwidths) or 80+80MHz (160MHz) (with non-contiguous bandwidths). In some embodiments, a 320 MHz channel bandwidth may be used. The scope of the embodiments is not limited with respect to the above center frequencies however.

[0031] FIG. 2 illustrates FEM circuitry 200 in accordance with some embodiments. The FEM circuitry 200 is one example of circuitry that may be suitable for use as the WLAN and/or BT FEM circuitry 104A/104B (FIG. I), although other circuitry configurations may also be suitable.

[0032] In some embodiments, the FEM circuitry 200 may include a TX/RX switch 202 to switch between transmit mode and receive mode operation. The FEM circuitry 200 may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry 200 may include a low-noise amplifier (LNA) 206 to amplify received RF signals 203 and provide the amplified received RF signals 207 as an output (e.g., to the radio IC circuitry 106 (FIG. 1)). The transmit signal path of the circuitry 200 may include a power amplifier (PA) to amplify input RF signals 209 (e.g., provided by the radio IC circuitry 106), and one or more filters 212, such as band-pass filters (BPFs), low-pass filters (LPFs) or other types of filters, to generate RF signals 215 for subsequent transmission (e.g., by one or more of the antennas 101 (FIG. 1)).

[0033] In some dual-mode embodiments for Wi-Fi communication, the

FEM circuitry 200 may be configured to operate in either the 2.4 GHz frequency spectrum or the 5 GHz frequency spectrum. In these embodiments, the receive signal path of the FEM circuitry 200 may include a receive signal path duplexer 204 to separate the signals from each spectrum as well as provide a separate

LNA 206 for each spectrum as shown. In these embodiments, the transmit signal path of the FEM circuitry 200 may also include a power amplifier 210 and a filter 212, such as a BPF, a LPF or another type of filter for each frequency spectrum and a transmit signal path duplexer 214 to provide the signals of one of the different spectrums onto a single transmit path for subsequent transmission by the one or more of the antennas 101 (FIG. 1). In some embodiments, BT communications may utilize the 2.4 GHZ signal paths and may utilize the same FEM circuitry 200 as the one used for WLAN communications.

[0034] FIG. 3 illustrates radio IC circuitry 300 in accordance with some embodiments. The radio IC circuitry 300 is one example of circuitry that may be suitable for use as the WLAN or BT radio IC circuitry 106A/106B (FIG. 1), although other circuitry configurations may also be suitable,

[0035] In some embodiments, the radio IC circuitry 300 may include a receive signal path and a transmit signal path. The receive signal path of the radio IC circuitry 300 may include at least mixer circuitry 302, such as, for example, down-conversion mixer circuitry, amplifier circuitry 306 and filter circuitry 308. The transmit signal path of the radio IC circuitry 300 may include at least filter circuitry 312 and mixer circuitry 314, such as, for example, up- conversion mixer circuitry. Radio IC circuitry 300 may also include synthesizer circuitry 304 for synthesizing a frequency 305 for use by the mixer circuitry 302 and the mixer circuitry 314. The mixer circuitry 302 and/or 314 may each, according to some embodiments, be configured to provide direct conversion functionality. The latter type of circuitry presents a much simpler architecture as compared with standard super-heterodyne mixer circuitries, and any flicker noise brought about by the same may be alleviated for example through the use of OFDM modulation. Fig. 3 illustrates only a simplified version of a radio IC circuitry, and may include, although not shown, embodiments where each of the depicted circuitries may include more than one component. For instance, mixer circuitry 320 and/or 314 may each include one or more mixers, and filter circuitries 308 and/or 312 may each include one or more filters, such as one or more BPFs and/or LPFs according to application needs. For exampie, when mixer circuitries are of the direct-conversion type, they may each include two or more mixers. [0036] In some embodiments, mixer circuitry 302 may be configured to down-convert RF signals 207 received from the FEM circuitry 104 (FIG. 1) based on the synthesized frequency 305 provided by synthesizer circuitry 304, The amplifier circuitry 306 may be configured to amplify the down-converted signals and the filter circuitry 308 may include a LPF configured to remove unwanted signals from the down-converted signals to generate output baseband signals 307. Output baseband signals 307 may be provided to the baseband processing circuitry 108 (FIG. 1) for further processing. In some embodiments, the output baseband signals 307 may be zero-frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 302 may comprise passive mixers, although the scope of the embodiments is not limited in this respect.

[0037] In some embodiments, the mixer circuitry 314 may be configured to up-convert input baseband signals 31 1 based on the synthesized frequency 305 provided by the synthesizer circuitry 304 to generate RF output signals 209 for the FEM circuitry 104. The baseband signals 311 may be provided by the baseband processing circuitry 108 and may be filtered by filter circuitry 312. The filter circuitry 312 may include a LPF or a BPF, although the scope of the embodiments is not limited in this respect.

[0038] In some embodiments, the mixer circuitry 302 and the mixer circuitry 314 may each include two or more mixers and may be arranged for quadrature down-conversion and/or up-conversion respectively with the help of synthesizer 304. In some embodiments, the mixer circuitry 302 and the mixer circuitry 314 may each include two or more mixers each configured for image rejection (e.g., Hartley image rejection). In some embodiments, the mixer circuitry 302 and the mixer circuitry 314 may be arranged for direct down- conversion and/or direct up-conversion, respectively. In some embodiments, the mixer circuitry 302 and the mixer circuitry 314 may be configured for superheterodyne operation, although this is not a requirement.

[0039] Mixer circuitry 302 may comprise, according to one embodiment: quadrature passive mixers (e.g., for the in-phase (I) and quadrature phase (Q) paths). In such an embodiment, RF input signal 207 from Fig. 3 may be down- converted to provide I and Q baseband output signals to be sent to the baseband processor.

[0040] Quadrature passive mixers may be driven by zero and ninety- degree time-varying LO switching signals provided by a quadrature circuitry which may be configured to receive a LO frequency (lL,o) from a local oscillator or a synthesizer, such as LO frequency 305 of synthesizer 304 (FIG. 3). In some embodiments, the LO frequency may be the carrier frequency, while in other embodiments, the LO frequency may be a fraction of the carrier frequency (e.g., one-half the carrier frequency, one-third the carrier frequency). In some embodiments, the zero and ninety-degree time-varying switching signals may be generated by the synthesizer, although the scope of the embodiments is not limited in this respect.

[0041] In some embodiments, the LO signals may differ in duty cycle

(the percentage of one period in which the LO signal is high) and/or offset (the difference between start points of the period). In some embodiments, the LO signals may have a 25% duty cycle and a 50% offset. In some embodiments, each branch of the mixer circuitry (e.g., the in-phase (I) and quadrature phase (Q) path) may operate at a 25% duty cycle, which may result in a significant reduction is power consumption.

[0042] The RF input signal 207 (FIG. 2) may comprise a balanced signal, although the scope of the embodiments is not limited in this respect. The I and Q baseband output signals may be provided to low-nose amplifier, such as amplifier circuitry 306 (FIG. 3) or to filter circuitry 308 (FIG, 3).

[0043] In some embodiments, the output baseband signals 307 and the input baseband signals 311 may be analog baseband signals, although the scope of the embodiments is not limited in this respect. In some alternate

embodiments, the output baseband signals 307 and the input baseband signals 31 1 may be digital baseband signals. In these alternate embodiments, the radio IC circuitry may include analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuitry.

[0044] In some dual-mode embodiments, a separate radio IC circuitry may be provided for processing signals for each spectrum, or for other spectmms not mentioned here, although the scope of the embodiments is not limited in this respect.

[0045] In some embodiments, the synthesizer circuitry 304 may be a fractional-N synthesizer or a fractional N/N+1 synthesizer, although the scope of the embodiments is not limited in this respect as other types of frequency synthesizers may be suitable. For example, synthesizer circuitry 304 may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider. According to some embodiments, the synthesizer circuitry 304 may include digital synthesizer circuitry. An advantage of using a digital synthesizer circuitry is that, although it may still include some analog components, its footprint may be scaled down much more than the footprint of an analog synthesizer circuitry. In some embodiments, frequency input into synthesizer circuity 304 may be provided by a voltage controlled oscillator (VCO), although that is not a requirement. A divider control input may further be provided by either the baseband processing circuitry 08 (FIG. 1) or the application processor 1 11 (FIG. 1) depending on the desired output frequency 305. In some embodiments, a divider control input (e.g., N) may be determined from a look-up table (e.g., within a Wi-Fi card) based on a channel number and a channel center frequency as determined or indicated by the application processor 1 11.

[0046] In some embodiments, synthesizer circuitry 304 may be configured to generate a carrier frequency as the output frequency 305, while in other embodiments, the output frequency 305 may be a fraction of the carrier frequency (e.g., one-half the carrier frequency, one-third the carrier frequency). In some embodiments, the output frequency 305 may be a LO frequency (fLo).

[0047] FIG. 4 illustrates a functional block diagram of baseband processing circuitry 400 in accordance with some embodiments. The baseband processing circuitry 400 is one example of circuitry that may be suitable for use as the baseband processing circuitry 108 (FIG. 1), although other circuitry configurations may also be suitable. The baseband processing circuitry 400 may include a receive baseband processor (RX BBP) 402 for processing receive baseband signals 309 provided by the radio IC circuitry 106 (FIG. 1) and a transmit baseband processor (TX BBP) 404 for generating transmit baseband signals 311 for the radio IC circuitry 106. The baseband processing circuitry 400 may also include control logic 406 for coordinating the operations of the baseband processing circuitry 400.

[0048] In some embodiments (e.g., when analog baseband signals are exchanged between the baseband processing circuitry 400 and the radio IC circuitry 106), the baseband processing circuitry 400 may include ADC 410 to convert analog baseband signals received from the radio IC circuitry 106 to digital baseband signals for processing by the RX BBP 402. In these

embodiments, the baseband processing circuitry 400 may also include DAC 412 to convert digital baseband signals from the TX BBP 404 to analog baseband signals.

[0049] In some embodiments that communicate OFDM signals or

OFDM A signals, such as through baseband processor 108 A, the transmit baseband processor 404 may be configured to generate OFDM or OFDMA signals as appropriate for transmission by performing an inverse fast Fourier transform (IFFT). The receive baseband processor 402 may be configured to process received OFDM signals or OFDMA signals by performing an FFT. In some embodiments, the receive baseband processor 402 may be configured to detect the presence of an OFDM signal or OFDMA signal by performing an autocorrelation, to detect a preamble, such as a short preamble, and by performing a cross-correlation, to detect a long preamble. The preambles may be part of a predetermined frame structure for Wi-Fi communication,

[0050] Referring back to FIG. 1, in some embodiments, the antennas 101 (FIG. 1) may each comprise one or more directional or omnidirectional antennas, including, for example, dipoie antennas, monopole antennas, patch antennas, loop antennas, microstrip antennas or other types of antennas suitable for transmission of RF signals. In some multiple-input multiple-output (MIMO) embodiments, the antennas may be effectively separated to take advantage of spatial diversity and the different channel characteristics that may result- Antennas 101 may each include a set of phased-array antennas, although embodiments are not so limited. [0051] Although the radio-architecture 100 is illustrated as having several separate functional elements, one or more of the functional elements may be combined and may be implemented by combinations of software-configured elements, such as processing elements including digital signal processors (DSPs), and/or other hardware elements. For example, some elements may comprise one or more microprocessors, DSPs, field-programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), radio-frequency integrated circuits (RFICs) and combinations of various hardware and logic circuitry for performing at least the functions described herein. In some embodiments, the functional elements may refer to one or more processes operating on one or more processing elements.

[0052] FIG. 5 illustrates a WLAN 500 in accordance with some embodiments. The WLAN 500 may comprise a basis service set (BSS) that may include a HE access point (AP) 502, which may be an AP, a plurality of high- efficiency wireless (e.g., IEEE 802.1 lax) (HE) stations 504, and a plurality of legacy (e.g., IEEE 802.1 ln/ac) devices 506.

[0053] The HE AP 502 may be an AP using the IEEE 802, 11 to transmit and receive. The HE AP 502 may be a base station. The HE AP 502 may use other communications protocols as well as the ΪΕΕΕ 802, 1 1 protocol. The IEEE 802, 1 protocol may be IEEE 802.1 lax. The IEEE 802.1 1 protocol may include using orthogonal frequency division multiple-access (OFDMA), time division multiple access (TDMA), and/or code division multiple access (CDMA). The IEEE 802.1 1 protocol may include a multiple access technique. For example, the IEEE 802.11 protocol may include space-division multiple access (SDMA) and/or multiple-user multiple-input multiple-output (MU-MIMO). There may be more than one HE AP 502 that is part of an extended service set (ESS). A controller (not illustrated) may store information that is common to the more than one HE APs 502.

[0054] The legacy devices 506 may operate in accordance with one or more of IEEE 802.1 1 a b/g/n/ac/ad/af/ah/aj/ay, or another legacy wireless communication standard. The legacy devices 506 may be stations (STAs) or IEEE STAs. The HE STAs 504 may be wireless transmit and receive devices such as cellular telephone, portable electronic wireless communication devices, smart telephone, handheld wireless device, wireless glasses, wireless watch, wireless personal device, tablet, or another device that may be transmitting and receiving using the IEEE 802.11 protocol such as IEEE 802.1 lax or another wireless protocol. In some embodiments, the HE STAs 504 may be termed high efficiency (HE) stations.

[0055] The HE AP 502 may communicate with legacy devices 506 in accordance with legacy IEEE 802, 1 1 communication techniques. In example embodiments, the HE AP 502 may also be configured to communicate with HE STAs 504 in accordance with legacy IEEE 802.11 communication techniques.

[0056] In some embodiments, a HE frame may be configurable to have the same bandwidth as a channel. The HE frame may be a physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). In some embodiments, there may be different types of PPDUs that may have different fields and different physical layers and/or different media access control (MAC) layers.

[0057] The bandwidth of a channel may be 20MHz, 40MHz, or 80MHz,

160MHz, 320MHz contiguous bandwidths or an 80+80MHz (160MHz) noncontiguous bandwidth. In some embodiments, the bandwidth of a channel may be 1 MHz, 1.25MHz, 2.03MHz, 2.5MHz, 4.06 MHz, 5MHz and I GMHz, or a combination thereof or another bandwidth that is less or equal to the available bandwidth may also be used. In some embodiments, the bandwidth of the channels may be based on a number of active data subcarriers. In some embodiments, the bandwidth of the channels is based on 26, 52, 106, 242, 484, 996, or 2x996 active data subcarriers or tones that are spaced by 20 MHz. In some embodiments, the bandwidth of the channels is 256 tones spaced by 20 MHz. In some embodiments, the channels are multiple of 26 tones or a multiple of 20 MHz. In some embodiments, a 20 MHz channel may comprise 242 active data subcarriers or tones, which may determine the size of a Fast Fourier Transform (FFT). An allocation of a bandwidth or a number of tones or sub- carriers may be termed a resource unit (RU) allocation in accordance with some embodiments. [0058] In some embodiments, the 26-subcarrier RU and 52-subcarrier

RU are used in the 20 MHz, 40 MHz, 80 MHz, 160 MHz and 80+80 MHz OFDMA HE PPDU formats. In some embodiments, the 106-subcarrier RU is used in the 20 MHz, 40 MHz, 80 MHz, 160 MHz and 80+80 MHz OFDMA and MU-MIMO HE PPDU formats. In some embodiments, the 242-subcarrier RU is used in the 40 MHz, 80 MHz, 160 MHz and 80+80 MHz OFDMA and MU- MIMO HE PPDU formats. In some embodiments, the 484-subearrier RU is used in the 80 MHz, 160 MHz and 80+80 MHz OFDMA and MU-MIMO HE PPDU formats. In some embodiments, the 996-subcarrier RU is used in the 160 MHz and 80+80 MHz OFDMA and MU-MIMO HE PPDU formats.

[0059] A HE frame may be configured for transmitting a number of spatial streams, which may be in accordance with MU-MIMO and may be in accordance with OFDMA. In other embodiments, the HE AP 502, HE STA 504, and/or legacy device 506 may also implement different technologies such as code division multiple access (CDMA) 2000, CDMA 2000 IX, CDMA 2000 Evolution-Data Optimized (EV-DO), Interim Standard 2000 (IS-2000), Interim Standard 95 (IS-95), Interim Standard 856 (IS-856), Long Term Evolution (LTE), Global System for Mobile communications (GSM), Enhanced Data rates for GSM Evolution (EDGE), GSM EDGE (GERAN), IEEE 802, 16 (i.e., Worldwide Interoperability for Microwave Access (WiMAX)), BlueTooth®, or other technologies.

[0060] Some embodiments relate to HE communications. In accordance with some IEEE 802.11 embodiments, e.g., IEEE 802.1 l ax embodiments, a HE AP 502 may operate as a master station which may be arranged to contend for a wireless medium (e.g., during a contention period) to receive exclusive control of the medium for an HE control period. In some embodiments, the HE control period may be termed a transmission opportunity (TXOP). The HE AP 502 may transmit a HE master-sync transmission, which may be a trigger frame or HE control and schedule transmission, at the beginning of the HE control period. The HE AP 502 may transmit a time duration of the TXOP and sub-channel information. During the HE control period, HE STAs 504 may communicate with the HE AP 502 in accordance with a non-contention based multiple access technique such as OFDM A or MU-MIMO. This is unlike conventional WLAN communications in which devices communicate in accordance with a contention-based communication technique, rather than a multiple access technique. During the HE control period, the HE AP 502 may communicate with HE stations 504 using one or more HE frames. During the HE control period, the HE ST As 504 may operate on a sub-channel smaller than the operating range of the HE AP 502, During the HE control period, legacy stations refrain from communicating. The legacy stations may need to receive the communication from the HE AP 502 to defer from communicating.

[0061] In accordance with some embodiments, during the TXOP the HE

STAs 504 may contend for the wireless medium with the legacy devices 506 being excluded from contending for the wireless medium during the master-sync transmission. In some embodiments the trigger frame may indicate an uplink (UL) UL-MU-MIMO and/or UL OFDM A TXOP, In some embodiments, the trigger frame may include a DL UL-MU-ΜΓΜΟ and/or DL OFDM A with a schedule indicated in a preamble portion of trigger frame.

[0062] In some embodiments, the multiple-access technique used during the HE TXOP may be a scheduled OFDMA technique, although this is not a requirement. In some embodiments, the multiple access technique may be a time-division multiple access (TD A) technique or a frequency division multiple access (FDMA) technique. In some embodiments, the multiple access technique may be a space-division multiple access (SDMA) technique. In some embodiments, the multiple access technique may be a Code division multiple access (CDMA).

[0063] The HE AP 502 may also communicate with legacy stations 506 and/or HE stations 504 in accordance with legacy IEEE 802.11 communication techniques. In some embodiments, the HE AP 502 may also be configurable to communicate with HE stations 504 outside the HE TXOP in accordance with legacy IEEE 802.11 communication techniques, although this is not a requirement. [0064] In some embodiments the HE station 504 may be a "group owner" (GO) for peer-to-peer modes of operation. A wireless device may be a HE station 502 or a HE AP 502.

[0065] In some embodiments, the HE station 504 and/or HE AP 502 may be configured to operate in accordance with IEEE 802.1 lmc. In example embodiments, the radio architecture of FIG. 1 is configured to implement the HE station 504 and/or the HE AP 502. In example embodiments, the front-end module circuitry of FIG. 2 is configured to implement the FIE station 504 and/or the HE AP 502. In example embodiments, the radio IC circuitry of FIG. 3 is configured to implement the HE station 504 and/or the HE AP 502. In example embodiments, the base-band processing circuitry of FIG. 4 is configured to impl ement the HE station 504 and/or the HE AP 502.

[0066] In example embodiments, the HE stations 504, HE AP 502, an apparatus of the HE stations 504, and/or an apparatus of the HE AP 502 may include one or more of the following: the radio architecture of FIG. 1, the front- end module circuitry of FIG. 2, the radio IC circuitry of FIG. 3, and/or the baseband processing circuitry of FIG. 4.

[0067] In example embodiments, the radio architecture of FIG. 1, the front-end module circuitry of FIG, 2, the radio IC circuitry of FIG. 3, and/or the base-band processing circuitry of FIG. 4 may be configured to perform the methods and operations/functions herein described in conjunction with FIGS, 6- 8.

[0068] In example embodiments, the HE station 504 and/or the HE AP

502 are configured to perform the methods and operations/functions described herein in conjunction with FIGS. 1-6, In example embodiments, an apparatus of the HE station 504 and/or an apparatus of the HE AP 502 are configured to perform the methods and functions described herein in conjunction with FIGS. 1 -6. The term Wi-Fi may refer to one or more of the IEEE 802.1 1

communication standards. AP and STA may refer to HE access point 502 and/or HE station 504 as well as legacy devices 506,

[0069] In some embodiments, a HE AP 502 or a HE STA 504 performing at least some functions of an HE AP 502 may be referred to as HE AP ST A. In some embodiments, a HE ST A 504 may be referred to as a HE non- AP STA. In some embodiments, a HE STA 504 may be referred to as either a HE AP STA and/or HE non-AP.

[0070] As the 6GHz band is currently being used by incumbent systems, there are regulations in place to protect the incumbent systems' use of the bandwidth. For example, the Federal Communications Commission (FCC) may require that any new system that uses the 6GHz band, address all incumbent system operating within the band currently. Various solutions are available. For example, solutions include part of the band (e.g., maybe a large part) could be excluded, incumbents could be moved off the band, or a very limited use in select areas of the 6GHz band. Moving incumbent systems from the 6GHz band, however, is impractical. The other approaches do not lead to a wide deployment of Wi-Fi with high spectral utilization. Furthermore, these approaches could require entire Wi-Fi networks to be moved off channels depending on activity. These issues would complicate network architectures and may affect ail devices in performance and power savings.

[0071] Besides satellite incumbent systems described above, there are fixed services terrestrial point-to-point links (FS) present in the 6GHz band. These P2P links are bi-directional and are allocated two channels with a specific bandwidth, one for downlink (DL) and one for uplink (UL).

[0072] FIG. 6 illustrates an example 800 of different fixed services (FS) point-to-point (P2P) links in a 5.5x5.5 mile geographic area grid, in accordance with some embodiments. Transmission direction of FS P2P links are shown in FIG. 8. Links are shown as lines 602, 604, 606, and 608. Different reference numbers indicate different transmission characteristics for the FS P2P links. Transmission characteristics may include the bandwidth used, transmission power, transmission schedule, etc.

[0073] A registry system, e.g., a database, may be used to store existing incumbents occupied bandwidths and the conditions to be respected to be able to use the channels occupied by these incumbents. In various examples, an AP may connect to this database and provide its geolocation information. In response, the AP may receive information on the available 6GHz channels. In addition, constraints that should he respected on any of the channels may also be provided. The geolocation information may include elevation of the AP.

[0074] The constraints may prohibit transmission on one or more of the channels. In addition, a constraint may be a max transmission (Tx) power constraint. In another example, a constrain may indicate that one or more measurements need to be done on specific bands/channels to show that the interference on an incumbent system is below a specific level . If the interference is above the specific level, then operation is not allowed on the channel. While, a calculated interface below the specific level allows operation on the channel. In an example, the measurement to be done may be indicated by the database. An example of measurement may be a satellite signal measurement to allow the Wi- Fi AP to ascertain the effective interference that the AP would generate on the satellite link.

[0075] In some embodiments, the information return from the database depends on the geolocation information provided by the AP. The geolocation information may have some imprecision. For instance, because the AP is indoor or because the AP is using a source of geolocation (e.g., cell ID of a cellular network) for which that accuracy is limited. The response from the database may be adapted based on the imprecision,

[0076] Described herein are enablement procedures for an AP in the

6GHz band that considers inaccurate geolocation information. In an example, the geolocation information provided is made of two components: the geolocation information (e.g., latitude, longitude, possibly including elevation) and an imprecision for each information (latitude, longitude, elevation). The

imprecision may be an error variance calculated by the AP based on the AP' s solution to estimate location. The imprecision may also be the method, e.g., GPS with xSNR, indoor Wi-Fi -based location technique, cell tower location, etc., that is used by the AP to acquire its geolocation information. The database may then lookup the error variance based on the geolocation information method.

[0077] In an example, both geolocation information components are estimated by the device and provided to the database. The database may identify an area within which the AP is located. Accordingly, the database may not consider a single exact point where the AP may be located. The database may generate a response to the AP by ensuring that the conditions to protect the incumbents are to be respected for all the points in the location area. Taking into all points allows for multiple incumbent systems. As an example, an area in which an AP may be located may include two position points. Each position point being in the line of sight of two FS incumbent system. The database response, therefore, takes into consideration the protection to these two FS incumbent systems. While if the geolocation information was a single point that was precise on one of the two position points, the response would ensure protection only to one FS incumbent.

[0078] As an example, an AP may access a database, such as the universal licensing system, and provide the database with the AP's (x,y,z) coordinates. For example, the coordinates may be latitude, longitude, and elevation. In addition, the AP may provide an imprecision indication, such as an error range and/or the coordinate determine method. The database may- determine a radius around the coordinate for an interference calculation. In another example, the AP may provide an initial radius to be used. In this example, the database may adjust the radius as needed. The database may then calculate the interference into each incumbent receiver located within the radius, The interference calculation may assume a -110 dBm/MHz. noise floor, an I/N= -6 dB which yields -116 dBm/MHz allowed aggregated radio local area network (RLAN) interference. In an example, an a-prior margin may be added for the aggregated interference. For example, the interference calculation may be based on a function of the AP's location and the number of available channels. The interference caused to FS receives may then be calculated. Interference protection zones may be established based on the calculated interference. This analysis may restrict Wi-Fi usage on various channels to ensure that the interference is below the desired threshold. In addition, the analysis may also determine the channels that are available in the radius for use by the AP. The analysis to determine the available channels may be repeated every week, biweekly, monthly, etc. The available channels may then be provided to the AP. Once received, the AP may use the available channels for Wi-Fi. The recalculations allow for updated incumbency data to be used. In an example, the available channels and transmit power limits may be encoded and transmitted to a station as part of a 6GHz access procedure.

[0079] In an example, an AP that operates in 5.925-6.425GHz and/or 6.525-6.875GHz bands with a conducted output power over the frequency band of operation greater than 250mW determine permissible frequencies of operation. The permissible frequencies calculation may be repeated every week, month, etc. An AP that operates in the 6.875-7.125MHz band may determine permissible frequencies of operation as well regardless of the conducted output power over the frequency. In an example, permissible channels of operation are identified by applying per-frequency exclusion zones. The exclusion zones may be determined by applying protection criteria. Protection criteria may be determined based on the type of incumbent. For example, FS may use a keyhole aligned with link path protection criteria. While a fixed and mobile broadcast auxiliary service (BAS) or cable TV relay service (CARS) may use a point/radius around a transmitter as the protection criteria. Once the exclusion zones are determined, the AP is not permitted to operate at frequencies and locations within the exclusion zones.

[0080] FIG. 7 illustrates an example 700 of an area 706 in which the AP/device can be in when providing the geolocation information along with an imprecision, in accordance with some embodiments. FIG. 7 does not consider elevation. A geolocation point 702 indicates a position where the AP may be located. In addition, an imprecision value 704 indicates an error level in the geolocation point 702. In an example, the AP is determined to be located anywhere within the area 706. The AP or the database may use the area 706 to determine any necessary AP operation restrictions to ensure that any existing systems are not interfered based on the AP's operation.

[0081] FIGS. 8A-8B illustrate an example scenario 800 where there are two incumbent fixed systems links FSI 812 and FS2 814, in accordance with some embodiments. Line 802 indicates the zone where protection for the FSI link 812 is needed. Line 814 indicates the zone where protection for the FS2 link 814 is needed. In FIG 8 A an AP provides its geolocation as point 820. In addition, an imprecision value 822 is associated with the geolocation point 820. In an example, the AP provides the imprecision value 822 to the database. The database may then determine the area 826 and determine that links FS1 812 and FS2 814 pass through the area 826 where the AP may be located. Accordingly, the operation of the AP may interfere with either or both of links FS 1 812 and FS2 814. The database may determine any operating restrictions for the AP to avoid interference with FS 1 812 and FS2 814. In an example, the database provides the AP with a maximum interference value. The AP may calculate its transmit power to avoid interfering with the FS 812 or FS 814 based on the maximum interference value.

[0082] FIG. 8B indicates a smaller imprecision value. For example, the geolocation point 830 is more precise compared to the geolocation point 820 from FIG. 8A. Thus, the area 836 to consider is smaller compared to the area 826 for a less precision geolocation value. Due to the more precise geolocation point 830, the database may return operating restrictions based on link FS 1 1 812 but not link FS2 814.

Considering examples in which modules are temporarily configured, each of the modules need not be instantiated at any one moment in time. For example, where the modules comprise a general-purpose hardware processor configured using software, the general-purpose hardware processor may be configured as respective different modules at different times. Software may accordingly configure a hardware processor, for example, to constitute a particular module at one instance of time and to constitute a different module at a different instance of time.

1000 upon which any one or more of the techniques (e.g., methodologies or operations) discussed herein may perform. The wireless device 1000 may be a HE device. The wireless device 1000 may be a HE STA 504 and/or HE AP 502 (e.g., FIG. 5). A HE STA 504 and/or HE AP 502 may include some or all of the components shown in FIGS. 1-5, 9, and 10. The wireless device 1000 may be an example machine 900 as disclosed in conjunction with FIG. 9.

[0098] The wireless device 1000 may include processing circuitry 1008.

The processing circuitry 1008 may include a transceiver 1002, physical layer circuitry (PHY circuitry) 1004, and MAC layer circuitry (MAC circuitry) 1006, one or more of which may enable transmission and reception of signals to and from other wireless devices 1000 (e.g., HE AP 502, HE STA 504, and/or legacy devices 506) using one or more antennas 1012.
