DETAILED DESCRIPTION

[0015] Example embodiments described herein provide certain systems, methods, and devices for EDMG information exchange. The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

[0016] Devices may communicate over a next generation 60 GHz (NG60) network, an enhanced directional multi-gigabit (EDMG) network, and/or any other network. Devices operating in EDMG may be referred to herein as EDMG devices. This may include user devices, and/or APs or other devices capable of communicating in accordance to a communication standard, including but not limited to IEEE 802.1 lad and/or IEEE 802.1 lay.

[0017] Task Group ay (TGay) is currently developing an amendment that will define modifications to the IEEE 802.11 physical layer (PHY) and medium access control (MAC) to enable stations operating in the license-exempt bands above 45 GHz a maximum throughput of at least 20 Gbps. To achieve this goal, TGay has defined a new physical layer convergence protocol (PLCP) data unit (PPDU) format, referred to as enhanced directional multi-gigabit (EDMG) PPDU format. IEEE 802.1 lay proposes to increase the transmission data rate applying multiple-input multiple-output (MIMO) and channel bonding techniques.

[0018] Channel bonding and channel aggregation are key features of IEEE 802.11 ay. An EDMG station device (STA) may need to announce its capability to support multiple channels in order to communicate with others. In addition, an EDMG AP and/or a personal basic service set control point (PCP) may need to announce the operating channels of the basic service set (BSS) so that all the associated STAs in the BSS are aware of the information. [0019] Example embodiments of the present disclosure relate to systems, methods, and devices for EDMG information exchange.

[0020] A directional multi-gigabit (DMG) communications may involve one or more directional links to communicate at a rate of multiple gigabits per second, for example, at least 1 gigabit per second, 7 gigabits per second, or any other rate. An amendment to a DMG operation in a 60 GHz band, e.g., according to an IEEE 802. Had standard, may be defined, for example, by an IEEE 802. Hay project.

[0021] In some demonstrative embodiments, one or more devices may be configured to communicate over a next generation 60 GHz (NG60) network, an enhanced DMG (EDMG) network, and/or any other network. For example, the one or more devices may be configured to communicate over the NG60 or EDMG networks.

[0022] IEEE 802. Had defined a transmission/reception protocol that described where the transmission could only occupy one of the channels. A channel would be associated with a specific bandwidth in the 60 GHz band. There were six channels that existed and therefore each transmission occupied one of those six channels. When an AP decides to establish a network, it will need to choose the channel and to advertise that information in a beacon frame. However, the only way for the STA to know the channel is to determine where the beacon frame is received.

[0023] IEEE 802.1 lay proposes to increase the transmission data rate applying MIMO and channel bonding techniques. In order to achieve that, the channel may need to be increased. For example, server 2 GHz bandwidth, it may be possible to use 4 GHz bandwidth, 6 GHz bandwidth, etc. In order to have this type of wide channel, there may be a couple of options. One option is to set a wide channel that spans over several channels. This is a continuous bandwidth used for transmission; this is referred to as a bonded channel. Any one of the channels may be channel bonded to create a bonded channel. Bonded channels may consist of contiguous or non-contiguous channels (e.g., subchannels may be bonded to form a bonded channel). For reference, the channels may be frequency channels. In this case, having the wider bandwidth, the transmission may carry more information resulting in higher throughput. Another option to expand the channel may be to use an aggregated channel. An aggregated channel may include one or more non-adjacent channels that may be aggregated together and used for the transmission between two devices. For example, if out of channels 1, 2, 3, 4, and 6, only channel 1 and 3 are available, and AP may aggregate channel 1 and 3 to be used for the transmission between two devices.

[0024] Currently there are limited ways a device can advertise the identity of the operating channels that may be used in a network. For example, an AP/PCP may advertise on a certain channel.

[0025] There is a motivation to lower the number of data being carried by a beacon frame because in the millimeter wave (mmWave) band, if a device needs to transmit something, it must be transmitted in a specific direction and it must be transmitted multiple times in different directions. A limited number of capabilities may be transmitted in the beacon frame. For example, if an STA wants to join the network, it will need some basic information derived from the received beacon frame in order to join the network. However, the AP/PCP is not able to include its extended capability in the beacon frame. The beacon frame only includes the supported channel bitmap and in the EDMG operation element, there is only a 3 bytes each indicating a channel number. This limits the operating channels of a BSS to four channels (one primary channel and up to three secondary channels). Another limitation of current standards is that if the AP/PCP wants to switch to another channel it is not possible to notify the STAs other than sending the beacon frame on the new channel. When the STA receives the beacon on the new channel, it would then know the new channel because the beacon was received on it. However, when there are multiple operating channels, the AP/PCP does not have a mechanism to inform the STAs of channel switching.

[0026] In one embodiment, an EDMG information exchange system may facilitate the exchange of an EDMG capabilities element, which may include channel numbers defined to describe what channels the EDMG device supports.

[0027] In one embodiment, an EDMG capabilities element may contain one or more fields that list all the possible combinations for an AP to support various channels. For example, the EDMG capabilities element may include a core capabilities field that is comprised of N+2M+4 octets that may be used to indicate to the STAs information associated with aggregated channels and non-aggregated channels. N indicates information of non-aggregated channels, and M indicates information of aggregated channels. N and M are determined based on the implementation. For example, some of the channels may be supported and some of the channels may not be supported. It should be noted that bonded channels may be non- aggregated channels.

[0028] If the AP wants to switch its primary channel, for example, if the AP was operating in channels 1, 2, 3, where channel 1 was the primary channel. In this case, the beacon frame would be transmitted on the primary channel 1. When the STA wants to transmit, it should transmit on channel 1, 2, or 3. However, if the AP performs its measurements and determines that there are interferences on channel 1, the AP may want to change its primary channel. In that, the AP may have determined that it needs to move to channels 3, 4, and 5. Therefore, the AP needs to inform the STA to tell it that the new primary is now channel 3. On channel 3, the AP may have sent a beacon frame, where the new operating channels are now 3, 4, and 5.

[0029] In one embodiment, an EDMG information exchange system may facilitate the exchange of an EDMG operation element, which may include channel numbers defined to describe what channels the EDMG infrastructure BSS/PBSS may operate. When an EDMG AP/PCP switches operating channels, it may use an Extended Channel Switch Announcement element to indicate the primary channel switch and may use EDMG operation element to indicate new operating channels. These elements provide clear definition of the channels supported by an EDMG device or an EDMG infrastructure BSS/PBSS. These rules for an EDMG STA to switch to a new operating channel fill the gap in current 802.1 lay standard in terms of multi-channel support.

[0030] The above descriptions are for purposes of illustration and are not meant to be limiting. Numerous other examples, configurations, processes, etc., may exist, some of which are described in greater detail below. Example embodiments will now be described with reference to the accompanying figures.

The user device(s) 120 may be referred to as stations (STAs). The user device(s) 120 may be mobile devices that are non- stationary and do not have fixed locations. Although the AP 102 is shown to be communicating on multiple antennas with user devices 120, it should be understood that this is only for illustrative purposes and that any user device 120 may also communicate using multiple antennas with other user devices 120 and/or AP 102.

[0032] In some embodiments, the user devices 120 and AP 102 may include one or more computer systems similar to that of the functional diagram of FIG. 9 and/or the example machine/system of FIG. 10.

[0033] One or more illustrative user device(s) 120 and/or AP 102 may be operable by one or more user(s) 110. The user device(s) 120 (e.g., 124, 126, or 128) and/or AP 102 may include any suitable processor-driven device including, but not limited to, a mobile device or a non- mobile, e.g., a static, device. For example, user device(s) 120 and/or AP 102 may include, a user equipment (UE), a station (STA), an access point (AP), a personal computer (PC), a wearable wireless device (e.g., bracelet, watch, glasses, ring, etc.), a desktop computer, a mobile computer, a laptop computer, an ultrabook^tm computer, a notebook computer, a tablet computer, a server computer, a handheld computer, a handheld device, an internet of things (IoT) device, a sensor device, a PDA device, a handheld PDA device, an on-board device, an off-board device, a hybrid device (e.g., combining cellular phone functionalities with PDA device functionalities), a consumer device, a vehicular device, a non-vehicular device, a mobile or portable device, a non-mobile or non-portable device, a mobile phone, a cellular telephone, a PCS device, a PDA device which incorporates a wireless communication device, a mobile or portable GPS device, a DVB device, a relatively small computing device, a non-desktop computer, a "carry small live large" (CSLL) device, an ultra mobile device (UMD), an ultra mobile PC (UMPC), a mobile internet device (MID), an "origami" device or computing device, a device that supports dynamically composable computing (DCC), a context-aware device, a video device, an audio device, an A/V device, a set-top-box (STB), a blu-ray disc (BD) player, a BD recorder, a digital video disc (DVD) player, a high definition (HD) DVD player, a DVD recorder, a HD DVD recorder, a personal video recorder (PVR), a broadcast HD receiver, a video source, an audio source, a video sink, an audio sink, a stereo tuner, a broadcast radio receiver, a flat panel display, a personal media player (PMP), a digital video camera (DVC), a digital audio player, a speaker, an audio receiver, an audio amplifier, a gaming device, a data source, a data sink, a digital still camera (DSC), a media player, a smartphone, a television, a music player, or the like. It is understood that the above is a list of devices. However, other devices, including smart devices such as lamps, climate control, car components, household components, appliances, etc., may also be included in this list.

[0034] Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may be configured to communicate with each other via one or more communications networks 130 and/or 135 wirelessly or wired. Any of the communications networks 130 and/or 135 may include, but not limited to, any one of a combination of different types of suitable communications networks such as, for example, broadcasting networks, cable networks, public networks (e.g., the Internet), private networks, wireless networks, cellular networks, or any other suitable private and/or public networks. Further, any of the communications networks 130 and/or 135 may have any suitable communication range associated therewith and may include, for example, global networks (e.g., the Internet), metropolitan area networks (MANs), wide area networks (WANs), local area networks (LANs), or personal area networks (PANs). In addition, any of the communications networks 130 and/or 135 may include any type of medium over which network traffic may be carried including, but not limited to, coaxial cable, twisted-pair wire, optical fiber, a hybrid fiber coaxial (HFC) medium, microwave terrestrial transceivers, radio frequency communication mediums, white space communication mediums, ultra-high frequency communication mediums, satellite communication mediums, or any combination thereof.

[0035] Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may include one or more communications antennas. The one or more communications antennas may be any suitable type of antennas corresponding to the communications protocols used by the user device(s) 120 (e.g., user devices 124, 126 and 128), and AP 102. Some non-limiting examples of suitable communications antennas include Wi-Fi antennas, Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards compatible antennas, directional antennas, non-directional antennas, dipole antennas, folded dipole antennas, patch antennas, multiple-input multiple-output (MIMO) antennas, omnidirectional antennas, quasi- omnidirectional antennas, or the like. The one or more communications antennas may be communicatively coupled to a radio component to transmit and/or receive signals, such as communications signals to and/or from the user devices 120 and/or AP 102.

[0036] Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may be configured to perform directional transmission and/or directional reception in conjunction with wirelessly communicating in a wireless network. Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may be configured to perform such directional transmission and/or reception using a set of multiple antenna arrays (e.g., DMG antenna arrays or the like). Each of the multiple antenna arrays may be used for transmission and/or reception in a particular respective direction or range of directions. Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may be configured to perform any given directional transmission towards one or more defined transmit sectors. Any of the user device(s) 120 (e.g., user devices 124, 126, 128), and AP 102 may be configured to perform any given directional reception from one or more defined receive sectors.

[0037] MIMO beamforming in a wireless network may be accomplished using RF beamforming and/or digital beamforming. In some embodiments, in performing a given MIMO transmission, user devices 120 and/or AP 102 may be configured to use all or a subset of its one or more communications antennas to perform MIMO beamforming.

[0038] Any of the user devices 120 (e.g., user devices 124, 126, 128), and AP 102 may include any suitable radio and/or transceiver for transmitting and/or receiving radio frequency (RF) signals in the bandwidth and/or channels corresponding to the communications protocols utilized by any of the user device(s) 120 and AP 102 to communicate with each other. The radio components may include hardware and/or software to modulate and/or demodulate communications signals according to pre-established transmission protocols. The radio components may further have hardware and/or software instructions to communicate via one or more Wi-Fi and/or Wi-Fi direct protocols, as standardized by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards. In certain example embodiments, the radio component, in cooperation with the communications antennas, may be configured to communicate via 2.4 GHz channels (e.g., 802.11b, 802. llg, 802.11η, 802.1 lax), 5 GHz channels (e.g., 802.11η, 802.1 lac, 802.1 lax), or 60 GHZ channels (e.g., 802. Had). In some embodiments, non-Wi-Fi protocols may be used for communications between devices, such as Bluetooth, dedicated short-range communication (DSRC), Ultra-High Frequency (UHF) (e.g., IEEE 802.11af, IEEE 802.22), white band frequency (e.g., white spaces), or other packetized radio communications. The radio component may include any known receiver and baseband suitable for communicating via the communications protocols. The radio component may further include a low noise amplifier (LNA), additional signal amplifiers, an analog-to-digital (A/D) converter, one or more buffers, and digital baseband.

[0039] A wireless communication channel may be comprised of a primary and a secondary channel. One of the reasons for the notion of primary and secondary channels is that it helps multiple networks to share the same frequency space. The primary channel may be used for devices that only support a certain bandwidth, while the secondary may be adjacent to the primary channel and may be aggregated with the primary channel in order to transmit over the specific bandwidth associated with the wireless communication channel. The primary channel forms the core frequency segment that the BSS (basic service set) or AP radio operates on, while the secondary channel(s) may be considered as extensions to the primary channel. For each channel bandwidth, there is one primary channel, meaning that it is the channel used to transmit frames at that channel width. In legacy devices (e.g., IEEE 802.1 lad), the primary channel is known to the receiving device since it is always set up to be the first portion of the wireless communication channel. Two devices may simultaneously transmit frames when their primary channels are different.

[0040] Some demonstrative embodiments may be used in conjunction with a wireless communication network communicating over a frequency band of 60 GHz (e.g., EDMG). However, other embodiments may be implemented utilizing any other suitable wireless communication frequency bands, for example, an extremely high frequency (EHF) band (the millimeter wave (mmWave) frequency band), a frequency band within the frequency band of between 20 GHz and 300 GHz, a WLAN frequency band, a WPAN frequency band, a frequency band according to the WGA specification, and the like.

[0041] The phrases "directional multi-gigabit (DMG)" and "directional band (DBand)", as used herein, may relate to a frequency band wherein the channel starting frequency is above 45 GHz. In one example, DMG communications may involve one or more directional links to communicate at a rate of multiple gigabits per second, for example, at least 1 gigabit per second, 7 gigabits per second, or any other rate.

[0042] In some demonstrative embodiments, the user device(s) 120 and/or the AP 102 may be configured to operate in accordance with one or more specifications, including one or more IEEE 802.11 specifications, (e.g., an IEEE 802.1 lad specification, an IEEE 802.1 lay specification, and/or any other specification and/or protocol).

[0043] In one embodiment, and with reference to FIG. 1, there is shown a capabilities exchange 140 between the user device(s) 120 and the AP(s) 102. Channel bonding and channel aggregation are key features of IEEE 802. Hay. An EDMG STA (e.g., a user device 120) may announce its capability to support multiple channels in order to communicate with others. In addition, an EDMG AP/PCP (e.g., AP 102) may announce the operating channels of the BSS so that all the associated STAs in the BSS are aware of the information. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

[0044] FIG. 2 depicts an illustrative schematic diagram 200 for channel definitions in IEEE 802.1 lay.

[0045] Currently, IEEE 802.1 lay defines non-aggregated channels. Those channels may be visualized as shown in FIG. 2. Specifically, channel numbers 1-6 are defined for 2.16 GHz channels, channel numbers 9-13 are defined for 4.32 GHz channel (channel bonding of 2), channel numbers 17-20 are defined for 6.48GHz channel (channel bonding of 3), and channel numbers 25-27 are defined for 8.64 GHz channel (channel bonding of 4). That is, when resources are allocated by an AP and/or a personal basic service set control point (PCP), the resources may be in a single 2.16 GHz or a bonded 2.16 GHz, where the bonding is based on a bonding factor. For example if the bonding factor is two using 2.16 GHz channels, this means that two adjacent channels are bonded together. This would result in 2.16 GHz channel bonded with an adjacent 2.16 GHz channel (e.g., channels 1 and 2), which would be a bonded channel of 4.32 GHz as shown in channel 9. It should be understood that although a bonding factor of 2 is used, the bonding factor may be 1, 2, 3, or 4.

[0046] However, directional multi-gigabit (DMG) STA operates on a single 2.16 GHz channel, while EDMG STAs may be operating on multiple channels depending on its supported channels as well as the operating channels of the EDMG BSS. Therefore, new rules to define the behavior of EDMG STAs when EDMG AP/PCP decides to switch to new operating channels may be needed.

[0047] FIG. 3 depicts an illustrative schematic diagram for EDMG capabilities information element (IE) format.

[0048] Referring to FIG. 3, there is shown one or more fields in an EDMG capabilities IE 300. For example, the EDMG capabilities IE 300 may comprise a core capabilities field 302 and one or more extended capabilities information fields. The core capabilities field 302 may include supported channels bitmap subfield 304, aggregated MAC protocol data unit (A- MPDU) parameters, PH supported subfield, and a reserved subfield. For example, current IEEE 802.1 lay standard defines the supported channels bitmap subfield 304 of an EDMG device using 8 bit of bitmap, where each bit in the bitmap corresponds to a 2.16 GHz channel.

[0049] The bitmap indication has the following drawbacks. First, a simple bitmap does not provide information on how channels are bonded or aggregated. For example, a bitmap of 11000000 indicates that the device supports channel 1 and 2. It is not clear if channel bonding of channel 1 and 2 or channel aggregation of channel 1 and 2 is supported.

[0050] In order to indicate the supported channels without confusion, one has to assume that all the possible channel bonding and channel aggregation options that are using the supported 2.16 GHz channels indicated by the bitmap shall be supported by the EDMG device. However, this may not be true. For example, an EDMG device with primary channel at channel 2 may support channel bonding of channel 1 and 2 and channel bonding of channel 2 and 3, and hence the bitmap should be set to 11100000. However, the device may not be able to support channel bonding of channel 1, 2, and 3.

[0051] FIG. 4 depicts an illustrative schematic diagram for EDMG operation IE format.

[0052] Referring to FIG. 4, there is shown an operation information element (IE) 400 that may be used by an AP/PCP in order to communicate information to an STA in an EDMG network and vice versa. The operation IE 400 may include at least in part an extended capabilities subfield 402.

[0053] Since a different EDMG STA may have different capabilities in supporting multiple channels, the operating channels of the infrastructure BSS/PBSS may be more than one. For example, an EDMG AP/PCP may need to advertise the operating channels that current infrastructure BSS/PBSS allows throughout the network. An EDMG operation element may be different, such as, there is a 3-byte BSS operating bandwidth field, with each byte containing a channel number. Referring to FIG. 4, this is shown in channel number of BW 1 subfield 404, channel number of BW 2 subfield 406, and channel number of BW 1 subfield 408. However, this design limits the operating channels of a BSS to 4 (e.g., the channel number of BW 1 subfield 404, channel number of BW 2 subfield 406, channel number of BW 3 subfield 408, and channel that this IE 400 is coming on (e.g., a primary channel)). However, again, the information contained in these fields does not identify channel aggregation combinations or channel bonding information.

[0054] FIG. 5 depicts an illustrative schematic diagram for an extended channel switch announcement IE 500 format.

[0055] The extended channel switch announcement information element 500 includes one or more fields. The one or more fields may be element ID, length, channel switch mode, new operating class, new channel number, and channel switch count.

[0056] Current IEEE 802.1 lay standard has not established rules for an EDMG BSS network to switch channels after establishing a communication link between devices, for example, between an AP/PCP and an STA. For DMG BSS network, however, the rules are as follows. When an DMG AP/PCP decides to switch to a new operating channel in an DMG BSS network, the DMG AP/PCP may inform associated STAs indicating that the AP/PCP is changing to a new channel and may maintain the association by advertising the switch using the extended channel switch announcement IE 500 in its transmitted DMG beacon frames, announce frames, and information response frames until the intended channel switch time. An STA that receives an extended channel switch announcement IE 500 may choose not to perform the specified switch, but to take alternative action.

[0057] However, a DMG STA operates on a single 2.16 GHz channel, where no aggregation or bonding of channels is used. On the other hand, an EDMG STA may be operating on multiple channels depending on its supported channels as well as the operating channels of the EDMG BSS. Therefore, new rules may be needed to define the behavior of EDMG STAs when EDMG AP/PCP decides to switch to new operating channels.

[0058] FIG. 6 depicts an illustrative schematic diagram for an EDMG capabilities IE 600 format, in accordance with one or more example embodiments of the present disclosure.

[0059] Referring to FIG. 6, there is shown an EDMG capabilities field comprising one or more fields. A non-AP or non-PCP EDMG STA declares that it is an EDMG STA by transmitting the EDMG Capabilities IE. The IE is present in Announce, Association Request, Association Response, Reassociation Request, Reassociation Response, Probe Request and Probe Response frames and can be present in DMG Beacon, Information Request, and Information Response frames. [0060] In one embodiment, an EDMG information exchange system may define an EDMG capabilities IE 600, which may be comprised, at least in part, of an element ID field, a length field, and extended ID extension field, a core capabilities field 602, which may be followed by one or more variable length Extended Capabilities fields.

[0061] In one embodiment, an EDMG information exchange system may define a core capabilities field 602 that may comprise a number of octets used to indicate to a receiving device (e.g., an STA) information associated with operating channels, aggregation of channels, or channel bonding. The core capabilities field 602 may provide, besides 7 bits of A-MPDU Parameters, 1 bit of PH Supported, and 8 reserved bits that are originally defined in the Core Capabilities field, N+1 octets of information of non-aggregated channels (e.g., information of non- aggregated channels subfield 604), and 2xM+l octets of information of aggregated channels (e.g., information of aggregated channels subfield 606) are included to replace the original 8 bits of Supported Channels Bitmap (e.g., bitmap 304 and FIG. 3).

[0062] In one embodiment, the Information of non- aggregated channels subfield 604 may comprise a number of non- aggregated channels subfield 605 and one or more non-aggregated channel numbers 607. The number of non-aggregated channels subfield 605 may have a length of one octet and may be used to indicate the number of non-aggregated channels (e.g., bonded channels). The one or more non- aggregated channels 607 may be comprised of N channel numbers that may be supported by an EDMG STA, where N is a positive integer. The one or more non-aggregated channels 607 may indicate the channel numbers that are bonded together. For example, the number of non-aggregated channel subfield 605 may be two and the non- aggregated channels subfield 607 may be channel 1 and channel 6.

[0063] In one embodiment, the information of aggregated channels subfield 606 may comprise a number of channel aggregation combinations subfield 609 and one or more channel aggregation combination 611. The number of channel aggregation combinations subfield 609 may have a length of one octet and may be used to indicate how many channels are aggregated. The number of channel aggregation combinations subfield 609 may be followed by M channel aggregation combinations, where each combination includes 2 channel numbers. If channel aggregation is not supported, the Number of channel aggregation combinations subfield may be set to 0.

[0064] It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

[0065] FIG. 7 depicts an illustrative schematic diagram for an EDMG operation IE 700 format, in accordance with one or more example embodiments of the present disclosure. [0066] Referring to FIG. 7, there is shown an EDMG operation IE 700 which may be comprised of one or more fields. The operational parameters of an EDMG BSS provided by an EDMG AP or EDMG PCP may be determined by the EDMG Operation IE 700. The EDMG Operation IE is transmitted in a management frame.

[0067] In one embodiment, an EDMG information exchange system may define the format of an EDMG operation IE 700 to comprise at least in part an element ID field, a length field, an element ID extension field, a primary channel field, a BSS ID field, an A-BFT parameters field, and a BSS operating channels field 702.

[0068] The BSS Operating Channels field 702 may include N+l octets of information of non- aggregated channels and 2xM+l octets of information of aggregated channels, where N and M are positive integers. . Similar to EDMG Capabilities IE 600 of FIG. 6, in the Information of non-aggregated channels subfield 703, there may be 1 octet of the Number of non- aggregated channels, 705 followed by N channel numbers 707 as the operating non- aggregated channels of an EDMG BSS. In the Information of aggregated channels subfield 704, there may be 1 octet of the Number of channel aggregation combinations, 709 followed by M channel aggregation combinations 711 with each combination including 2 channel numbers. If channel aggregation is not allowed in the EDMG BSS operation, the Number of channel aggregation combinations subfield may be set to 0.

[0069] In one embodiment, an EDMG AP/PCP may decide to switch to new operating channels in an EDMG BSS, similar to DMG scenario, the EDMG AP/PCP may inform associated STAs by advertising the switch using an Extended Channel Switch Announcement element in its transmitted DMG Beacon frames, Announce frames, and Information Response frames until the intended channel switch time.

[0070] In one embodiment, an EDMG information exchange system may facilitate that the new channel number and the new operating class in the Extended Channel Switch Announcement element may indicate the channel number and the operating class of the new primary channel. An EDMG STA may receive an Extended Channel Switch Announcement element and may choose not to perform the specified switch, but to take alternative action. However, if the EDMG STA decides to perform the specified switch, it may remain on the new primary channel as indicated by the new channel number in the Extended Channel Switch Announcement element until it receives the updated BSS Operating Channels in the EDMG operation element from the EDMG AP/PCP, which it is associated to. After receiving the updated BSS Operating Channels in the EDMG operation element from the EDMG AP/PCP, the EDMG STA may operate on any channel that is included in the BSS Operating Channels. It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

[0071] FIG. 8 A illustrates a flow diagram of illustrative process 800 for an illustrative EDMG information exchange system, in accordance with one or more example embodiments of the present disclosure.

[0072] At block 802, a device (e.g., the user device(s) 120 and/or the AP(s) 102 of FIG. 1) determine a primary channel of one or more channels in an EDMG frequency band. For example, an AP (or PCP) may decide on which primary channel it wants to operate (e.g., channel number 2 of FIG. 2).

[0073] At block 804, the device may cause to send a beacon frame to a station device of one or more station devices, wherein the beacon frame comprises a first information element indicating basic service set (BSS) operating channels of the one or more channels. The AP may want to advertise the primary channel information to the STAs (e.g., user devices 120 of FIG. 1). The AP may accomplish that using one or more frames (e.g., a beacon frame, an announce frame, or any other management frame). Continuing with the example, the AP may transmit its beacons on channel number 2 (primary channel in this example). Each beacon frame may also incorporate an EDMG operation IE (e.g., the EDMG operation IE 700 of FIG. 7). This EDMG operation IE may list the operating channels including the primary channel number 2. For example, the list of operating channels may include the primary channel number 2 and two other channels, channel number 3 and channel number 18. If channel aggregation is not allowed in the EDMG BSS operation, the Number of channel aggregation combinations subfield may be set to 0.

[0074] At block 806, the device may identify a first frame received from a station device, wherein the first frame comprises a first capability indication associated with one or more first operating channels. For example, the STA may receive the beacon frame from the AP/PCP and may identify a BSS operating channels which include the primary channel. The STA would then determine to use the BSS operating channels in order to initiate link establishment with the AP/PCP.

[0075] At block 808, the device may cause to send a second frame to the station device, wherein the second frame comprises a second capability indication associated with one or more second operating channels. After link establishment, the STA may send a management frame (e.g., a probe request) to the AP/PCP indicating its operating channels capability. For example, the STA may be capable in communicating in one or more channel numbers listed in FIG. 2. The STA may indicate for example that it is capable of operating on channel number 1, channel number 2, channel number 9, etc. It should be understood that the capability depends on various implementation considerations, for example, country specific, hardware design constraints, or other implementation considerations.

[0076] At block 810, the device may cause to send a third frame on a third operating channel that is included in the one or more first operating channels and the one or more second operating channels. When the AP receives the information about the operating channels capability of the STA, the AP may use a management frame (e.g., probe response) to the STA indicating its own operating channels capability. When the STA identifies the operating channels capability of the AP from the management frame it receives, the STA and the AP would then choose a set of commonly supported channels in order to continue communicating. The AP may decide to move to other channel due to interferences it experience on some of its operated channels. In that case, the AP may send to all of its associated STAs a management frame with extended channel switch announcement element which indicates to the STA what will be the next primary channel it about to switch to (e.g., from primary channel number 2 to primary channel number 4). It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

[0077] FIG. 5B illustrates a flow diagram of illustrative process 850 for a high efficiency signal field coding system, in accordance with one or more example embodiments of the present disclosure.

[0078] At block 852, a device (e.g., the user device(s) 120 and/or the AP 102 of FIG. 1) may identify a beacon frame received from a device, wherein the beacon frame comprises a first information element indicating service set (BSS) operating channels of one or more channels. For example in STA (e.g., a user device 120) may receive a beacon frame from an AP/PCP that may have sent the beacon frame on a primary channel. The beacon frame may also contain an IED associated with BSS operating channels that the AP may be using for this communication.

[0079] At block 854, the device may initiate a link establishment using a primary channel included in the BSS operating channels. For example, when the STA receives the beacon frame and knowing the BSS operating channels, the STA may utilize these channels to establish a link with the AP/PCP.

[0080] At block 856, the device may cause to send a frame to the device indicating a capability indication associated with one or more first operating channels. After link establishment, the STA may use a management frame (e.g., a probe request) to send to the AP/PCP. This management frame may include information associated with channels that the STA is capable of communicating on. For example the STA may indicate in one of the fields of the management frame that its operating channel capability include one or more channels (e.g., channel numbers shown in FIG. 2).

[0081] At block 858, the device may identify a second frame received from the device, wherein the second frame comprises a second capability indication associated with one or more second operating channels. For example, the AP may send a management frame (e.g., a probe response) to the STA indicating the AP's operating channels capability. It should be understood that the capability depends on various implementation considerations, for example, country specific, hardware design constraints, or other implementation considerations. When the STA identifies the operating channels capability of the AP from the management frame it receives, the STA and the AP would then choose a set of commonly supported channels in order to continue communicating. In some instances, the AP may decide to move to other channel due to interferences it experience on some of its operated channels. In that case, the AP may send to all of its associated STAs a management frame with extended channel switch announcement element which indicates to the STA what will be the next primary channel it about to switch to (e.g., from primary channel number 2 to primary channel number 4). It is understood that the above descriptions are for purposes of illustration and are not meant to be limiting.

[0082] FIG. 9 shows a functional diagram of an exemplary communication station 900 in accordance with some embodiments. In one embodiment, FIG. 9 illustrates a functional block diagram of a communication station that may be suitable for use as an AP 102 (FIG. 1) or a user device 120 (FIG. 1) in accordance with some embodiments.

[0086] In some embodiments, the communication station 900 may include one or more antennas 901. The antennas 901 may include 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 embodiments, instead of two or more antennas, a single antenna with multiple apertures may be used. In these embodiments, each aperture may be considered a separate antenna. In some multiple-input multiple-output (MIMO) embodiments, the antennas may be effectively separated for spatial diversity and the different channel characteristics that may result between each of the antennas and the antennas of a transmitting station. [0087] In some embodiments, the communication station 900 may include one or more of a keyboard, a display, a non-volatile memory port, multiple antennas, a graphics processor, an application processor, speakers, and other mobile device elements. The display may be an LCD screen including a touch screen.

[0088] Although the communication station 900 is illustrated as having several separate functional elements, two 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 include 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.

[0090] FIG. 10 illustrates a block diagram of an example of a machine 1000 or system upon which any one or more of the techniques (e.g., methodologies) discussed herein may be performed. In other embodiments, the machine 1000 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 1000 may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine 1000 may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environments. The machine 1000 may be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile telephone, a wearable computer device, a web appliance, a network router, a switch or bridge, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine, such as a base station. Further, while only a single machine is illustrated, the term "machine" shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), or other computer cluster configurations.

[0091] 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 when operating. A module includes hardware. In an example, the hardware may be specifically configured to carry out a specific operation (e.g., hardwired). In another example, the hardware may include configurable execution units (e.g., transistors, circuits, etc.) and a computer readable medium containing instructions where the instructions configure the execution units to carry out a specific operation when in operation. The configuring may occur under the direction of the executions units or a loading mechanism. Accordingly, the execution units are communicatively coupled to the computer-readable medium when the device is operating. In this example, the execution units may be a member of more than one module. For example, under operation, the execution units may be configured by a first set of instructions to implement a first module at one point in time and reconfigured by a second set of instructions to implement a second module at a second point in time.

[0092] The machine (e.g., computer system) 1000 may include a hardware processor 1002 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 1004 and a static memory 1006, some or all of which may communicate with each other via an interlink (e.g., bus) 1008. The machine 1000 may further include a power management device 1032, a graphics display device 1010, an alphanumeric input device 1012 (e.g., a keyboard), and a user interface (UI) navigation device 1014 (e.g., a mouse). In an example, the graphics display device 1010, alphanumeric input device 1012, and UI navigation device 1014 may be a touch screen display. The machine 1000 may additionally include a storage device (i.e., drive unit) 1016, a signal generation device 1018 (e.g., a speaker), an EDMG information exchange device 1019, a network interface device/transceiver 1020 coupled to antenna(s) 1030, and one or more sensors 1028, such as a global positioning system (GPS) sensor, a compass, an accelerometer, or other sensor. The machine 1000 may include an output controller 1034, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate with or control one or more peripheral devices (e.g., a printer, a card reader, etc.)).

[0093] The storage device 1016 may include a machine readable medium 1022 on which is stored one or more sets of data structures or instructions 1024 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 1024 may also reside, completely or at least partially, within the main memory 1004, within the static memory 1006, or within the hardware processor 1002 during execution thereof by the machine 1000. In an example, one or any combination of the hardware processor 1002, the main memory 1004, the static memory 1006, or the storage device 1016 may constitute machine -readable media.

[0094] The EDMG information exchange device 1019 may carry out or perform any of the operations and processes (e.g., processes 800 and 850) described and shown above. For example, the EDMG information exchange device 1019 may facilitate the exchange of an EDMG capabilities element, which may include channel numbers defined to describe what channels the EDMG device supports.

[0095] The EDMG information exchange device 1019 may facilitate the exchange of an EDMG capabilities element, which may include channel numbers defined to describe what channels the EDMG device supports.

[0096] The EDMG information exchange device 1019 may define an EDMG capabilities element that may contain one or more fields that list all the possible combinations for an AP to support various channels. For example, the EDMG capabilities element may include a core capabilities field that is comprised of N+2M+4 octets that may be used to indicate to the STAs information associated with aggregated channels and non-aggregated channels. N indicates information of non-aggregated channel, and M indicates information of aggregated channels. N and M are determined based on the implementation. For example, some of the channels may be supported and some of the channels may not be supported. It should be noted that bonded channels may be non-aggregated channels. If the AP wants to switch its primary channel, for example, if the AP was operating in channels 1, 2, 3, where channel 1 was the primary channel. In this case the beacon frame would be transmitted on the primary channel 1. When the STA wants to transmit, it should transmit on channel 1, 2, or 3. However, if the AP performs its measurements and determines that there are interferences on channel 1, the AP may want to change its primary channel. In that, the AP may have determined that it needs to move to channels 3, 4, and 5. Therefore, the AP needs to inform the STA to tell it that the new primary is now channel 3. On channel 3, the AP may have sent a beacon frame, where the new operating channels are now 3, 4, and 5.

[0097] The EDMG information exchange device 1019 may facilitate the exchange of an EDMG operation element, which may include channel numbers defined to describe what channels the EDMG infrastructure BSS/PBSS may operate. When an EDMG AP/PCP switches operating channels, it may use an Extended Channel Switch Announcement element to indicate the primary channel switch and may use EDMG operation element to indicate new operating channels. These elements provide clear definition of the channels supported by an EDMG device or an EDMG infrastructure BSS/PBSS. These rules for an EDMG STA to switch to a new operating channel fill the gap in current 802.1 lay standard in terms of multichannel support.

[0098] It is understood that the above are only a subset of what the EDMG information exchange device 1019 may be configured to perform and that other functions included throughout this disclosure may also be performed by the EDMG information exchange device 1019.

[0099] While the machine-readable medium 1022 is illustrated as a single medium, the term "machine-readable medium" may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 1024.

[00100] Various 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; a flash memory, etc.

[00101] The term "machine-readable medium" may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine 1000 and that cause the machine 1000 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding, or carrying data structures used by or associated with such instructions. Non-limiting machine-readable medium examples may include solid-state memories and optical and magnetic media. In an example, a massed machine -readable medium includes a machine-readable medium with a plurality of particles having resting mass. Specific examples of massed machine -readable media may include non-volatile memory, such as semiconductor memory devices (e.g., electrically programmable read-only memory (EPROM), or electrically erasable programmable read-only memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD- ROM disks.

[00102] The instructions 1024 may further be transmitted or received over a communications network 1026 using a transmission medium via the network interface device/transceiver 1020 utilizing any one of a number of transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communications networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), plain old telephone (POTS) networks, wireless data networks (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi®, IEEE 802.16 family of standards known as WiMax®), IEEE 802.15.4 family of standards, and peer-to-peer (P2P) networks, among others. In an example, the network interface device/transceiver 1020 may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network 1026. In an example, the network interface device/transceiver 1020 may include a plurality of antennas to wirelessly communicate using at least one of single- input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) techniques. The term "transmission medium" shall be taken to include any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine 1000 and includes digital or analog communications signals or other intangible media to facilitate communication of such software. The operations and processes described and shown above may be carried out or performed in any suitable order as desired in various implementations. Additionally, in certain implementations, at least a portion of the operations may be carried out in parallel. Furthermore, in certain implementations, less than or more than the operations described may be performed.

Similarly, the bidirectional exchange of data between two devices (both devices transmit and receive during the exchange) may be described as "communicating," when only the functionality of one of those devices is being claimed. The term "communicating" as used herein with respect to a wireless communication signal includes transmitting the wireless communication signal and/or receiving the wireless communication signal. For example, a wireless communication unit, which is capable of communicating a wireless communication signal, may include a wireless transmitter to transmit the wireless communication signal to at least one other wireless communication unit, and/or a wireless communication receiver to receive the wireless communication signal from at least one other wireless communication unit.

[00105] As used herein, unless otherwise specified, the use of the ordinal adjectives "first," "second," "third," etc., to describe a common object, merely indicates that different instances of like objects are being referred to and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.

[00106] The term "access point" (AP) as used herein may be a fixed station. An access point may also be referred to as an access node, a base station, an evolved node B (eNodeB), or some other similar terminology known in the art. An access terminal may also be called a mobile station, user equipment (UE), a wireless communication device, or some other similar terminology known in the art.
