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
[0039] In some embodiments, the radio-architecture 100 may include other radio cards, such as a cellular radio card configured for cellular (e.g., 3GPP such as LTE, LTE-Advanced or 5G communications).

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.
[0041] 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. 1), although other circuitry configurations may also be suitable.
[0042] 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))·
[0043] 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.
[0044] 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.
[0045] 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 example, when mixer circuitries are of the direct-conversion type, they may each include two or more mixers.
[0046] 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.
[0047] 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 31 1 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.
[0048] 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.
[0049] 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
[0050] 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 (fro) 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.
[0051] 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.
[0052] 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).
[0053] In some embodiments, the output baseband signals 307 and the input baseband signals 31 1 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.
[0054] In some dual-mode embodiments, a separate radio IC circuitry may be provided for processing signals for each spectrum, or for other spectrums
not mentioned here, although the scope of the embodiments is not limited in this respect.
[0055] 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 108 (FIG. 1) or the application processor 1 1 1 (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 1 1.
[0056] 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).
[0057] 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 31 1 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.
[0058] 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.
[0059] In some embodiments that communicate OFDM signals or
OFDMA signals, such as through baseband processor 108A„ 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.
[0060] 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, dipole 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.
[0061] 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.
[0062] 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 1n/ac) devices 506.
[0063] The HE AP 502 may be an AP using the IEEE 802.1 1 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 IEEE 802.1 1 protocol. The IEEE 802.1 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.
[0064] 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 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 802.1 1 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.
[0065] 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 802.1 1 communication techniques.
[0066] 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.
[0067] 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 10MHz, 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.
[0068] 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-subcarrier 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.
[0069] 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.
[0070] Some embodiments relate to HE communications. In accordance with some IEEE 802.1 1 embodiments, e.g, IEEE 802.1 lax 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 OFDMA 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 STAs 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.
[0071] 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 OFDMA TXOP. In some embodiments, the trigger frame may include a DL UL-MU-MIMO and/or DL OFDMA with a schedule indicated in a preamble portion of trigger frame.
[0072] 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 (TDMA) 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).
[0073] The HE AP 502 may also communicate with legacy stations 506 and/or HE stations 504 in accordance with legacy IEEE 802.1 1 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 802.1 1 communication techniques, although this is not a requirement.
[0074] 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.
[0075] 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.

502 are configured to perform the methods and operations/functions described herein in conjunction with FIGS. 1-22. 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. 1-22. 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.
[0079] In some embodiments, a HE AP STA may refer to a HE AP 502 and a HE STAs 504 that is operating a HE APs 502. In some embodiments, when an HE STA 504 is not operating as a HE AP, it may be referred to as a HE non-AP STA or HE non-AP. In some embodiments, HE STA 504 may be referred to as either a HE AP STA or a HE non-AP.
[0080] In some embodiments, the HE STA 504 is configured to operate on multiple bands, e.g., 2.4 GHz, 5 GHz, 6 GHz, and/or 60 GHz. HE STA 504 may be non-concurrent, in accordance with some embodiments. For example,
HE STA 504 may be able to be active on only one band at a time. HE STA 504 may be non-concurrent, in accordance with some embodiments. For example,
HE STA 504 may be able to be active on only one band at a time.
[0081] FIG. 6 illustrates a block diagram of an example machine 600 upon which any one or more of the techniques (e.g., methodologies) discussed herein may perform. In alternative embodiments, the machine 600 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 600 may operate in the capacity of a server machine, a client machine, or both in server-client network environments.

[0092] Examples, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. Modules are tangible entities (e.g., hardware) capable of performing specified operations and may be configured or arranged in a certain manner. In an example, circuits may be arranged (e.g., internally or with respect to external entities such as other circuits) in a specified manner as a module. In an example, the whole or part of one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware processors may be configured by firmware or software (e.g., instructions, an application portion, or an application) as a module that operates to perform specified operations. In an example, the software may reside on a machine readable medium. In an example, the software, when executed by the underlying hardware of the module, causes the hardware to perform the specified operations.
[0093] Accordingly, the term "module" is understood to encompass a tangible entity, be that an entity that is physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operation described herein. 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.
[0094] Some embodiments may be implemented fully or partially in software and/or firmware. This software and/or firmware may take the form of instructions contained in or on a non-transitory computer-readable storage medium. Those instructions may then be read and executed by one or more processors to enable performance of the operations described herein. The instructions may be in any suitable form, such as but not limited to source code, compiled code, interpreted code, executable code, static code, dynamic code, and the like. Such a computer-readable medium may include any tangible non- transitory medium for storing information in a form readable by one or more computers, such as but not limited to read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory, etc.

700 upon which any one or more of the techniques (e.g., methodologies or operations) discussed herein may perform. The wireless device 700 may be a HE device. The wireless device 700 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. 1-7.

[0097] Accordingly, the PHY circuitry 704 and the transceiver 702 may be separate components or may be part of a combined component, e.g., processing circuitry 708. In addition, some of the described functionality related to transmission and reception of signals may be performed by a combination that may include one, any or all of the PHY circuitry 704 the transceiver 702, MAC circuitry 706, memory 710, and other components or layers.

In some multiple-input multiple-output (MIMO) embodiments, the antennas 712 may be effectively separated to take advantage of spatial diversity and the different channel characteristics that may result.
[0099] One or more of the memory 710, the transceiver 702, the PHY circuitry 704, the MAC circuitry 706, the antennas 712, and/or the processing circuitry 708 may be coupled with one another. Moreover, although memory 710, the transceiver 702, the PHY circuitry 704, the MAC circuitry 706, the antennas 712 are illustrated as separate components, one or more of memory
710, the transceiver 702, the PHY circuitry 704, the MAC circuitry 706, the antennas 712 may be integrated in an electronic package or chip.
[00100] In some embodiments, the wireless device 700 may be a mobile device as described in conjunction with FIG. 6. In some embodiments the wireless device 700 may be configured to operate in accordance with one or more wireless communication standards as described herein (e.g., as described in conjunction with FIGS. 1-6, IEEE 802.1 1). In some embodiments, the wireless device 700 may include one or more of the components as described in conjunction with FIG. 6 (e.g., display device 610, input device 612, etc.) Although the wireless device 700 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.
[00101] In some embodiments, an apparatus of or used by the wireless device 700 may include various components of the wireless device 700 as shown in FIG. 7 and/or components from FIGS. 1-6. Accordingly, techniques and operations described herein that refer to the wireless device 700 may be applicable to an apparatus for a wireless device 700 (e.g., HE AP 502 and/or HE STA 504), in some embodiments. In some embodiments, the wireless device 700 is configured to decode and/or encode signals, packets, and/or frames as described herein, e.g., PPDUs.
[00102] In some embodiments, the MAC circuitry 706 may be arranged to contend for a wireless medium during a contention period to receive control of the medium for a HE TXOP and encode or decode an HE PPDU. In some embodiments, the MAC circuitry 706 may be arranged to contend for the
wireless medium based on channel contention settings, a transmitting power level, and a clear channel assessment level (e.g., an energy detect level).
[00103] The PHY circuitry 704 may be arranged to transmit signals in accordance with one or more communication standards described herein. For example, the PHY circuitry 704 may be configured to transmit a HE PPDU. The PHY circuitry 704 may include circuitry for modulation/demodulation, upconversion/downconversion, filtering, amplification, etc. In some embodiments, the processing circuitry 708 may include one or more processors. The processing circuitry 708 may be configured to perform functions based on instructions being stored in a RAM or ROM, or based on special purpose circuitry. The processing circuitry 708 may include a processor such as a general purpose processor or special purpose processor.

In some embodiments, the processing circuitry 708 may be configured to perform one or more of the functions/operations and/or methods described herein.
[00104] In mmWave technology, communication between a station (e.g., the HE stations 504 of FIG. 5 or wireless device 700) and an access point (e.g., the HE AP 502 of FIG. 5 or wireless device 700) may use associated effective wireless channels that are highly directionally dependent. To accommodate the directionality, beamforming techniques may be utilized to radiate energy in a certain direction with certain beamwidth to communicate between two devices. The directed propagation concentrates transmitted energy toward a target device in order to compensate for significant energy loss in the channel between the two communicating devices. Using directed transmission may extend the range of the millimeter-wave communication versus utilizing the same transmitted energy in omni-directional propagation.
[00105] FIG. 8 illustrates multi-band operation (MBO) with dual connectivity in accordance with some embodiments. Illustrated in FIG. 8 is HE
AP 502, HE stations 504, HE stations 504, and communications 810. The HE
AP 502 may be the same or similar as HE AP 502 as illustrated in FIG. 5. HE
AP 502 may be configured to operate on multiple bands, e.g., 2.4 GHz, 5 GHz,
and band 3, which may be another band, e.g., 60 GHz or 6 GHz. The different bands may be divided between different APs, e.g., referring to FIG. 9, HE AP 502 may be configured to operate on 2.4 GHz and 5 GHz, and 6 GHz AP 902 may be configured to operate on 6 GHz.
[00106] The HE stations 504 may be the same or similar as HE stations
504 as illustrated in FIG. 5. The HE stations 504 may be configured to operate on multiple bands, e.g., 2.4 GHz, 5 GHz, band 3, which may be another band, e.g., 60 GHz or 6 GHz. The HE stations 504 may be configured to operate on different bands than the HE AP 502.
[00107] Communication 810 may be communication between the HE AP
502 and one or more HE stations 504. The communication 810 may include a type of traffic 808 and band 806. In some embodiments, the type of traffic 808 may be a management frame, a control frame, or data frame. The band 806 may be a frequency band, e.g., 2.4 GHz, 5 GHz, 6 GHz, 60 GHz, etc. In some embodiments, the type of traffic 808 may be limited for some bands 806, e.g., only data for 6 GHz and 60 GHz.
[00108] In some embodiments, the HE stations 504 may maintain two or more connections with two different APs, which may be co-located or non co- located. For example, HE AP 502 may be two or co-located APs with one AP operating on band 3 and another AP operating on 2.4 GHz or 5 GHz. In some embodiments, different data streams may be steered independently from the others. For example, HE station 504.1 may be connected with two AP that are co-located at EH AP 502. Communication 810.1 may be a first data stream and connection 810.2 may be a second data stream, where the communication 810.1 is between a first AP of HE AP 502 and the HE station 504, and communication 810.1 is between a second AP of HE AP 502 and the HE station 504.
[00109] In some embodiments, HE AP 502 may perform a fast session transfer (FST) where a stream of data is transferred to band 3, e.g., the stream of data may be voice over internet protocol (VoIP) or a stream of video from an Internet site. For example, HE AP 502 may determine booster link parameters 1 100 and send them to the HE station 504 and/or the co-located secondary AP (band 3), 6 GHz AP 902, and/or HE AP 502 (FIG. 10).
[00110] In some embodiments, the HE AP 502, HE station 504, and/or secondary-AP may exchange multi-band capabilities. In some embodiments, the HE AP 502 may advise/request that the HE station 504 and/or secondary-AP switch streams (i.e., to or from the secondary AP).
[00111] FIG. 9 illustrates a system for dynamic physical parameters for a
6 GHz band, in accordance with some embodiments. Illustrated in FIG. 9 is HE AP 502, signal area of HE AP 806, 6 GHz APs 802, signal area of 6 GHz APs 804, HE stations 504, and controller 808.
[00112] The HE AP 502 may be the same or similar to the HE AP 502 of FIG. 5. HE stations 504 may be the same or similar as HE stations 504 of FIG. 5. HE AP 502 and/or HE station 504 may be configured to operate on multi- bands, e.g., 2.4 GHz, 5 GHz, 6 GHz, 6-7 GHz, and/or 60 GHz. For example, HE AP 502 may be the same or similar as HE AP 502 of FIG. 8.
[00113] The signal area of HE AP 806 indicates an area where the radio- frequency signals (e.g., 2.4 GHz and/or 5 GHz) received from the HE AP 502 are above a threshold level where the threshold level may be level that would enable a station (e.g., HE stations 504) to communicate with the HE AP 502. The signal area of 6 GHz APs 804 indicates an area where the radio-frequency signals received from the G GHz APs 802 are above a second threshold level where the second threshold level may be a level that would enable a station (e.g., HE stations 504) to communicate with the 6 GHz AP 802. For example, HE station 504.3 is within the signal area of 6 GHz AP 902.1 and the signal area of HE AP 806, and thus may be able to communicate with 6 GHz AP 902 and HE AP 502. HE station 504.2 is outside the signal area of 6 GHz AP 902.1 and thus may not be able to communicate with 6 GHz AP 902.1 ; however, HE station 504.2 is within the signal area of HE AP 806 and thus may be able to communicate with HE AP 502. HE station 504.4 may be outside signal area of HE AP 806 and thus may not be able to communicate with HE AP 502.
[00114] The controller 908 may be a controller that has access to the internet and may provide one or more services to HE AP 502 and/or 6 GHz AP 902.2. The controller 908 may be co-located with HE AP 502 and/or 6 GHz AP 902.2. The controller 908 may be connected via a wireless or wired connection 942 to HE AP 502 and 6 GHz AP 902.2. In some embodiments, HE station
504.1 may be associated with HE AP 502. In some embodiments, the controller 908 may control the access of HE station 504.1 to 6 GHz AP 902.2. For example, HE station 504.1 may associate with HE AP 502, and then the parameters needed for HE station 504.1 to communicate with 6 GHz AP 902.2 may be transmitted via communication 940.1, e.g., booster link parameters 1 100. In some embodiments, the HE station 504.1 does not associate with 6 GHz AP 902.2.
[00115] In some embodiments, HE AP 502, 6 GHz AP 902.2, and the controller 908 are all co-located. In some embodiments, the 6 GHz APs 902 operate in Greenfield mode without being able to operate with legacy devices, e.g., IEEE 802.1 lac.
[00116] In some embodiments, other devices, which may be termed incumbents, may be transmitting on one of the bands being used by the HE AP 502 and/or 6 GHz APs 902, e.g., 6 GHz. For example, uplink (UL) satellites applications may be using 6 GHz. The bandwidth of the incumbents may vary between 200 KHz to 35- 100 MHz in accordance with some embodiments.
[00117] In some embodiments, the HE AP 502 comprises a database (DB) 903 that includes information regarding the incumbents. For example, the bandwidth and frequency used by the incumbents.
[00118] In some embodiments, the link between the HE station 504.1 and the HE AP 502 is termed an anchor interface. In some embodiments, all the management frames are transmitted across the anchor interface (e.g., using communication 940). In some embodiments, most of the management frames are transmitted across the anchor interface (e.g., using communication 940).
[00119] In some embodiments, HE station 504.1 cannot associate with 6
GHz APs 902. In some embodiments, the PHY layer of the 6 GHz APs 902 is not compatible with the PHY layer of the HE AP 502 (2.4 GHz band and/or 5 GHz band). In some embodiments, the HE stations 504 cannot scan for the 6 GHz APs 902 and directly associate with the 6 GHz AP 902. In some embodiments, the HE stations 504 associates with the 6 GHz AP 902 via the HE AP 502.
[00120] In some embodiments, the PHY design used to communicate with
6 GHz AP 902 is flexible and changes based on the incumbents. In some
embodiments, a center frequency and/or a bandwidth used to communicate with the 6 GHz AP 902 by the HE stations 504 may depend on the incumbents. In some embodiments, some part of the bandwidth of the 6 GHz band used to communicate with the 6 GHz AP 902 may be muted or not modulated (or modulated with a lower transmit power, TxP) in order to avoid incumbents. In some embodiments, when OFDM is used, the subcamers are not modulated. In some embodiments, a description of the tones or subcamers that are to be muted (e.g., to avoid incumbents) is included in the booster link parameters 1 100.
[00121] FIG. 10 illustrates a system for dynamic physical parameters for a 6 GHz band, in accordance with some embodiments. Illustrated in FIG. 10 is a HE AP 502, signal area of 6 GHz HE AP 1004, signal area of 2.5/5 GHz HE AP 502, and HE stations 504. HE AP 502 may be the same or similar to HE AP 502 of FIG. 5. HE AP 502 may be a multi-band AP. HE AP 502 may be a co- located anchor/booster AP. Signal area of 6 GHz HE AP 1004 may indicate the area where signals from a 6 GHz band of HE AP 502 are above a threshold level. For example, HE station 504.2 may be within signal area of 6 GHz HE AP 1004 and may communicate with the HE AP 502 using the 6 GHz band. HE station 504.3 may be outside the signal area of 6 GHz HE AP 1004 and may not be able to communicate with the HE AP 502 over the 6 GHz band.
[00122] Signal area of 2.5/5 GHz HE AP 1006 may indicate the area where signals from a 2.5/5 GHz band of HE AP 502 are above a threshold level. For example, HE stations 504.2 and 504.3 may be within signal area of 2.5/5 GHz HE AP 1006 and may communicate with the HE AP 502 using the 2.5/5 GHz band. HE station 504.1 may be outside the signal area of 2.5/5 GHz HE AP 1006 and may not be able to communicate with the HE AP 502 over the 2.5/5 GHz band (or the 6 GHz band).
[00123] HE stations 504 may associate with HE AP 502 via a 2.5/5 GHz band and receive parameters (e.g., booster link parameters 1 100) to receive and/or transmit to a 6 GHz band of the HE AP 502 or a co-located AP. The HE AP 502 may be configured to communicate with the co-located AP to determine a configuration for the co-located AP and/or receive a configuration from the co- located AP and communicate the configuration to the HE stations 504.
[00124] FIG. 1 1 illustrates a booster link parameters element 1 100 in accordance with some embodiments. Booster link parameters element 1 100 may include booster link PHY parameters 1 102 and/or booster link MAC parameters 1 104. Booster link PHY parameters 1 102 may include PHY parameters for the operation of a booster link (e.g., band 3 of FIG. 8, 6 GHz APs 902, 6 GHz band of HE AP 502). Booster link PHY parameters 1 102 may include one or more of: a band, a resource unit (RU), a transmit power, a time, a center frequency, bandwidth, subcarrier spacing, transmit power regulatory limit, and/or fast Fourier transform (FFT) size. Booster link MAC parameters 1 104 may include MAC parameters for the operation of a booster link (e.g., band 3 of FIG. 8, 6
GHz APs 902, 6 GHz band of HE AP 502). Booster link MAC parameters 1 104 may include one or more of: acknowledgement rules, packet format, and/or retransmit rules. Booster link parameters element 1 100 may be the same or similar as booster link parameters element 1200.
[00125] FIGS. 12-17 will be disclosed in conjunction with one another.
FIG. 12 illustrates a PHY design in accordance with some embodiments.
Illustrated in FIG. 12 is HE AP 502, DB 903, associated stations 1218, predetermined channel information 1220, and booster link parameters 1200. The HE AP 502 may be configured to generate booster link parameters 1200 based on one or more of predetermined channel information 1220, associated stations 1218, and DB 903. Associated stations 1218 may be stations that are associated with the HE AP 502, e.g., HE station 504.2 may be associated with HE AP 502 of FIG. 9.
[00126] DB 903 may comprise incumbents 1202. The incumbents 1202 may be indicated by one or more of the following: a frequency range 1204 and signal strength 1206. The frequency range 1204 may be a range of a frequency. The signal strength 1206 may be a signal strength 1206 of the incumbent 1202. In some embodiments, signal strength 1206 is a measure of a transmit power (TxP) that a station (e.g., HE station 504) may use to avoid interfering with the incumbent 1202. In some embodiments, the signal strength 1206 is measured by the HE AP 502 and, in some embodiments, is adjusted for a position of the station. Example incumbents 1202 include incumbents 1310 (FIG. 13), 1410 (FIG. 14), 1510 (FIG. 15), 1610 (FIG. 16), and 1710 (FIG. 17).
[00127] Predetermined channel information 1220 may include frequency range 1222 and predetermined channels 1224. Frequency range 1222 may be a range for resource unit (RU), which may be a frequency range assigned for a transmission to or from a secondary AP, e.g., 6 GHz band of the HE AP 502 or a co-located AP (FIG. 10), 6 GHz APs 902, and band 3 of HE AP 502 (of FIG. 8).
[00128] Predetermined channels 1224 may be channel or frequency ranges that have been predetermined. For example, RUs 1506, 160 MHz channel 1602, and 160 MHz channel 1702 are predetermined channels 1224.
[00129] Booster link parameters 1200 may include RU 1208, transmit power 1210, service period 1212, center frequency 1214, band 1215, and additional parameters 1216. Booster link parameters 1200 may be the same or similar as booster link parameters 1 100.

[00131] TxP 1210 may indicate a transmit power that may be used on the
RU 1208. TxP 1210 may be a value in mWs or mW / IMHz, in accordance with some embodiments. In some embodiments, TxP 1210 may be a value indicating a power spectral density (PSD) that may be used for the RU 1208.
[00132] Service period 1212 may be a value that indicates when a station (e.g., HE station 504) is to receive or may transmit a transmission in accordance with the other booster link parameters 1200. For example, service period 1212 may be service period 1902 and/or service period 2002. Center frequency 1214 may be a center frequency of a RU 1208 or frequency band to transmit or receive frames.
[00133] Additional parameters may include one or more additional parameters. For example, one or more of the parameters as disclosed in conjunction with FIG. 11. In some embodiments, there booster link parameters element 1200 may include booster link PHY parameters and/or booster link MAC parameters as disclosed in conjunction with FIG. 1 1. Band 1215 may indicate a band, e.g., 6 GHz or 60 GHz. In some embodiments, band 1215 may be a base and RU 1208 a base for a frequency range.

PHY parameters and/or booster link MAC parameters. Booster link parameters 1200 may be a resource allocation that allocates resources to transmit to or receive from a secondary AP.
[00134] In some embodiments, the HE AP 502 may receive a frame from an incumbent. The frame from the incumbent may include an indication of a maximum interference the incumbent can tolerate and an indication of a transmit power used to transmit the frame. The HE AP 502 may determine the transmit power 1210 based on the transmit power used to transmit the frame and the maximum interference, e.g., by assuming the attenuation for transmitting the frame is the same as for receiving the frame.
[00135] In some embodiments, the HE AP 502 configures both the HE station 504 and the secondary AP, e.g., HE AP 502 (FIG. 10), 6 GHz AP 902, and HE AP 502 (FIG. 8) band 3, with one or more parameters of the booster link parameters 1200. In some embodiments, the HE AP 502 configures the secondary AP using a non-wireless communication, e.g., co-located
communication for HE AP 502 of FIGS. 8 and 1 1, and via the controller 908 for FIG. 9.
[00136] FIG. 13 illustrates a PHY design in accordance with some embodiments. Illustrated in FIG. 13 is frequency 1302 along a vertical axis, transmit power 1304 along a horizontal axis, RUs 1208, incumbents 1310, and regulatory limit 1306. RUs 1308 may have a frequency range 1312. The transmit power 1314.1, 1314.2 may indicate a power that may be used to transmit frames using the RUs 1308.1, 1308.2, respectively. In some embodiments, the booster link parameters 1200 for the PHY design of FIG. 13 may include may include a RU 1208 and an indication of a TxP 1210 that may be used. In some embodiments, the resource allocation may indicate a maximum power spectral density (PSD) that may be used to transmit on the RU 1208.
[00137] In some embodiments, the HE AP 502 may be configured to determine booster link parameters 1200 as follows. RU 1308.1 may be determined to include the frequency range 1312.2 because the TxP 1314.1 is sufficient for a station to use to communicate with a secondary AP and is not greater than the signal strength 1316 of incumbents 1310. In some
embodiments, HE AP 502 may divide frequency range 1312.2 into multiple RUs.
[00138] HE AP 502 may determine frequency range 1312.1 based on TxP
1314.2 being greater than signal strength 1316.1 of incumbent 1310. And, TxP 1314.2 being less than the signal strength 1316.2 so that transmitting on RU
1308.2 will not interfere with incumbent 1310.1. In some embodiments, the HE AP 502 may determine a received signal strength 1316 based on received signals of the incumbents 1310. In some embodiments, the HE AP 502 may adjust the transmit power 1314 that the HE stations 504 may use to transmit on the RU 1308 based on a position of the HE stations 504. In some embodiments, the HE AP 502 may be configured to determine the frequency ranges 1312 based on the incumbents 1310. In some embodiments, the HE AP 502 may be configured to determine the frequency ranges 1312 based on a transmit power 1304 that the HE stations 504 need to use to communicate with the HE AP 502 and/or a secondary AP or band.
[00139] The frequency range 1312 may be 320 MHz in accordance with some embodiments. In some embodiments, the frequency range 1312 may be a different value, e.g., 20 MHz, 40 MHz, 80 MHz, 160 MHz, 640 MHz, 1.280 GHz, etc. In some embodiments, the HE AP 502 may adjust the frequency ranges 1312 to a predefined frequency range or channel size, e.g., 20 MHz, 40 MHz, 80 MHz, 160 MHz, or 320 MHz.
[00140] In some embodiment, the RU 1308 may be termed overlapping
RUs 1308 because they overlap with the incumbents 1310. In some
embodiments, overlapping RUs 1308 with incumbents 1310 is permitted if the PSD and/or TxP that will be used on the RU 1308 is below a threshold. In some embodiments, the HE AP 502 may determine to mute one or more subcarriers of RU 1312.1 so there is a buffer between RU 1312.1 and incumbent 1310.2, e.g. 1 to 100 subcarriers.
[00141] FIG. 14 illustrates a PHY design in accordance with some embodiments. Illustrated in FIG. 14 is frequency 1402 along a vertical axis, transmit power 1404 along a horizontal axis, RUs 1408, incumbents 1410, and regulatory limit 1406. RUs 1408 may have a frequency range 1412. The transmit power 1414 may indicate a power that may be used to transmit frames
using the RUs 1408.1, 1408.2, respectively. In some embodiments, the booster link parameters 1200 for the PHY design of FIG. 13 may include may include a RU 1208 and an indication of a TxP 1210 that may be used. In some embodiments, the resource allocation may indicate a maximum PSD that may be used to transmit on the RU 1208.
[00142] The HE AP 502 may be configured to determine RU 1412.1 and
RU 1412.2 based on the TxP 1414 to be used for communication on the RUs 1412 being too great for incumbent 1410.2 with a signal strength 1416.1. In some embodiments, the HE AP 502 determines to mute some subcarriers, e.g., the subcarriers used by incumbent 1410.2. In some embodiments, the HE AP 502 determines to not include some subcarriers between the incumbent 1410.2 and RUs 1412.2 and 1412.1 so as not lower the interference caused between the incumbent 1410.2 and the RUs 1412.1, 1412.2. In some embodiments, the HE AP 502 determines to include the subcarriers of incumbent 1410.1 with RU 1412.1 because the signal strength or TxP of incumbent 1416.2 is greater than the TxP 1414 to be used for transmissions on RU 1408.1. Muting or not using subcarriers used by the incumbent 1410.2 may be termed notching in accordance with some embodiments.
[00143] In some embodiments, the HE AP 502 may be configured to determine the RUs 1412 based on expanding the frequency range 1412 to lower the PSD or TxP 1414 to use on the RU 1408.1 below the signal strength 1416 (or interference level) of incumbent 1410.1.
[00144] In some embodiments, the booster link parameters 1200 for the
PHY design of FIG. 14 may include may include a RU 1208 and an indication of a TxP 1210 that may be used. In some embodiments, the resource allocation may indicate a maximum power spectral density (PSD) that may be used to transmit on the RU 1208.
[00145] In some embodiments, the HE AP 502 and/or HE station 504 mute tones in the whole bandwidth. In some embodiments, the number of subcarriers per OFDM symbol (Nb) is variable and determined by the HE AP 502 and/or HE station 504.

channels 1580, RUs 1582, and frames 1584. The predefined channels 1580 may be 16 10 MHz RUs 1506 over a 160 MHz channel 1502.
[00147] The RU 1582 may be RU 1508.1, RU 1508.6 through 1508.10, and RU 1508.13 through 1508.16. The HE AP 502 may determine RU 1582 based on excluding predefined channels 1580 that may interfere with the incumbents 1510. In some embodiments, a threshold number of subcarriers on either side of the incumbents 1510 are muted to lower the possibility of interference with the incumbents 1510. In some embodiments, the HE AP 502 determines whether the predefined channels 1580 may interfere with the incumbents 1510 based on determining a TxP to use on the predefined channels 1580 (which may be lowered by using larger RUs 1582).
[00148] In some embodiments, the frames 1584 may be 1512. The stations and/or secondary AP or band, may transmit frames 1512 with a short training field (STF), a long training field (LTF), and a signal field (SIG) on each 10 MHz RU 1506. In some embodiments, the stations and/or secondary AP or band, may transmit frames 1512 with a full bandwidth (BW) SIG, e.g., the full BW SIG and a STF and LTF that are transmitted across using the full BW.
[00149] In some embodiments, the booster link parameters 1200 for the
PHY design of FIG. 15 may include may include a RU 1208 by indicating a number of predefined channels 1508. In some embodiments, the booster link parameters 1200 may include an indication of a TxP 1210 that may be used.

Incumbents 1752 may include incumbents 1710. The non-interfered RUs 1754 may be RUs where a predefined channel 1750 is not interfered with by an incumbent, e.g., 160 MHz channel 1702.1 is not interfered with by an incumbent 1710.
[00153] The interfered RUs 1756 may include RUs 1710 where a predefined channel 1750 is interfered with by an incumbent 1710. For example, RU 1710.1 is part of predefined channel 160 MHz channel 1702.2 that is interfered with by incumbent 1710.1. The RUs 1710 may be the largest portion of the predefined channels 1750 that are not interfered with by an incumbent 1710. In some embodiments, subcarriers (e.g., 1 to 30) are mute beside the incumbents 1710 to lower the interference between the incumbents 1710 and the transmissions on the RU 1710.

For example, service period 2002 may include one or more fields to enable a negotiation of parameters between a HE AP 502 and HE station 504, and/or between a HE AP 502 and secondary AP 1802.
[00159] Returning to the method 1800, the method 1800 may begin with section negotiate parameters 1850, which may include operations 1810 and 1814. For example, method 1800 may begin with operation 1810 with negotiate parameters 1810. Negotiate parameters 1810 may include the HE station 504 associating with the HE AP 502, which may assign an association identification (AID) to the HE station 504 and update associated stations 1219 (FIG. 12). Negotiate parameters 1810 may include transmitting an element 1808, which may be service period 1902 or service period 2002.
