For example, the chip or SoC may include one or more elements of controller 154, one or more elements of message processor 158, and/or one or more elements of radio 144. In one example, controller 154, message processor 158, and radio 144 may be implemented as part of the chip or SoC. [0073] In other embodiments, controller 154, message processor 158 and/or radio 144 may be implemented by one or more additional or alternative elements of device 140.

[0075] In some demonstrative embodiments, device 102 and/or device 140 may include, operate as, perform the role of, and/or perform one or more functionalities of, one or more DMG STAs.

[0077] In some demonstrative embodiments, device 102 and/or device 140 may be configured operate as, perform the role of, and/or perform one or more functionalities of, an access point (AP), e.g., a DMG AP, and/or a personal basic service set (PBSS) control point (PCP), e.g., a DMG PCP, for example, an AP/PCP STA, e.g., a DMG AP/PCP STA.

[0079] In other embodiments, device 102 and/or device 140 may operate as, perform the role of, and/or perform one or more functionalities of, any other additional or alternative device and/or station.

[0080] In one example, a station (STA) may include a logical entity that is a singly addressable instance of a medium access control (MAC) and physical layer (PHY) interface to the wireless medium (WM). The STA may perform any other additional or alternative functionality.

[0081] In one example, an AP may include an entity that contains a station (STA), e.g., one STA, and provides access to distribution services, via the wireless medium (WM) for associated STAs. The AP may perform any other additional or alternative functionality. [0082] In one example, a personal basic service set (PBSS) control point (PCP) may include an entity that contains a STA, e.g., one station (STA), and coordinates access to the wireless medium (WM) by STAs that are members of a PBSS.

[0083] In one example, a PBSS may include a directional multi-gigabit (DMG) basic service set (BSS) that includes, for example, one PBSS control point (PCP). For example, access to a distribution system (DS) may not be present, but, for example, an intra-PBSS forwarding service may optionally be present. [0084] In one example, a PCP/AP STA may include a station (STA) that is at least one of a PCP or an AP. The PCP/AP STA may perform any other additional or alternative functionality.

[0085] In one example, a non-AP STA may include a STA that is not contained within an AP. The non-AP STA may perform any other additional or alternative functionality.

[0086] In one example, a non-PCP STA may include a STA that is not a PCP. The non-PCP STA may perform any other additional or alternative functionality.

[0087] In one example, a non PCP/AP STA may include a STA that is not a PCP and that is not an AP. The non-PCP/AP STA may perform any other additional or alternative functionality.

[0088] In some demonstrative embodiments devices 102 and/or 140 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, devices 102 and/or 140 may perform Multiple-Input-Multiple-Output (MIMO) communication, for example, for communicating over the NG60 and/or EDMG networks, e.g., over an NG60 or an EDMG frequency band.

[0089] In some demonstrative embodiments, devices 102 and/or 140 may be configured to operate in accordance with one or more Specifications, for example, including one or more IEEE 802.11 Specifications, e.g., an IEEE 802.11-2016 Specification, an IEEE 802. Hay Specification, and/or any other specification and/or protocol.

[0090] Some demonstrative embodiments may be implemented, for example, as part of a new standard in an mmWave band, e.g., a 60GHz frequency band or any other directional band, for example, as an evolution of an IEEE 802.11-2016 Specification and/or an IEEE 802.1 lad Specification.

[0091] In some demonstrative embodiments, devices 102 and/or 140 may be configured according to one or more standards, for example, in accordance with an IEEE 802.1 lay Standard, which may be, for example, configured to enhance the efficiency and/or performance of an IEEE 802. Had Specification, which may be configured to provide Wi-Fi connectivity in a 60 GHz band. [0092] Some demonstrative embodiments may enable, for example, to significantly increase the data transmission rates defined in the IEEE 802. Had Specification, for example, from 7 Gigabit per second (Gbps), e.g., up to 30 Gbps, or to any other data rate, which may, for example, satisfy growing demand in network capacity for new coming applications.

[0093] Some demonstrative embodiments may be implemented, for example, to allow increasing a transmission data rate, for example, by applying MIMO and/or channel bonding techniques.

[0094] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate MIMO communications over the mmWave wireless communication band.

[0095] In some demonstrative embodiments, device 102 and/or device 140 may be configured to support one or more mechanisms and/or features, for example, channel bonding, Single User (SU) MIMO, and/or Multi-User (MU) MIMO, for example, in accordance with an IEEE 802.1 lay Standard and/or any other standard and/or protocol.

[0096] In some demonstrative embodiments, device 102 and/or device 140 may include, operate as, perform a role of, and/or perform the functionality of, one or more EDMG STAs. For example, device 102 may include, operate as, perform a role of, and/or perform the functionality of, at least one EDMG STA, and/or device 140 may include, operate as, perform a role of, and/or perform the functionality of, at least one EDMG STA.

[0097] In some demonstrative embodiments, devices 102 and/or 140 may implement a communication scheme, which may include Physical layer (PHY) and/or Media Access Control (MAC) layer schemes, for example, to support one or more applications, and/or increased transmission data rates, e.g., data rates of up to 30 Gbps, or any other data rate.

[0098] In some demonstrative embodiments, the PHY and/or MAC layer schemes may be configured to support frequency channel bonding over a mmWave band, e.g., over a 60 GHz band, SU MIMO techniques, and/or MU MIMO techniques.

[0099] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more mechanisms, which may be configured to enable SU and/or MU communication of Downlink (DL) and/or Uplink frames (UL) using a MIMO scheme.

[00100] In some demonstrative embodiments, device 102 and/or device 140 may be configured to implement one or more MU communication mechanisms. For example, devices 102 and/or 140 may be configured to implement one or more MU mechanisms, which may be configured to enable MU communication of DL frames using a MIMO scheme, for example, between a device, e.g., device 102, and a plurality of devices, e.g., including device 140 and/or one or more other devices.

[00101] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate over an NG60 network, an EDMG network, and/or any other network and/or any other frequency band. For example, devices 102 and/or 140 may be configured to communicate DL MIMO transmissions and/or UL MIMO transmissions, for example, for communicating over the NG60 and/or EDMG networks. [00102] Some wireless communication Specifications, for example, the IEEE 802.11ad-2012 Specification, may be configured to support a SU system, in which a STA may transmit frames to a single STA at a time. Such Specifications may not be able, for example, to support a STA transmitting to multiple STAs simultaneously, for example, using a MU-MEVIO scheme, e.g., a DL MU-MIMO, or any other MU scheme.

[00103] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more mechanisms, which may, for example, enable to extend a single-channel BW scheme, e.g., a scheme in accordance with the IEEE 802.1 lad Specification or any other scheme, for higher data rates and/or increased capabilities, e.g., as described below.

[00104] In one example, the single-channel BW scheme may include communication over a 2.16 GHz channel (also referred to as a "single-channel" or a "DMG channel").

[00105] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support communication over a channel BW (also referred to as a "wide channel", an "EDMG channel", or a "bonded channel") including two or more channels, e.g., two or more 2.16 GHz channels, e.g., as described below .

[00106] In some demonstrative embodiments, the channel bonding mechanisms may include, for example, a mechanism and/or an operation whereby two or more channels, e.g., 2.16 GHz channels, can be combined, e.g., for a higher bandwidth of packet transmission, for example, to enable achieving higher data rates, e.g., when compared to transmissions over a single channel. Some demonstrative embodiments are described herein with respect to communication over a channel BW including two or more 2.16 GHz channels, however other embodiments may be implemented with respect to communications over a channel bandwidth, e.g., a "wide" channel, including or formed by any other number of two or more channels, for example, an aggregated channel including an aggregation of two or more channels.

[00107] In some demonstrative embodiments, device 102 and/or device 140 may be configured to implement one or more channel bonding mechanisms, which may, for example, support an increased channel bandwidth, for example, a channel BW of 4.32 GHz, a channel BW of 6.48 GHz, a channel BW of 8.64 GHz, and/or any other additional or alternative channel BW, e.g., as described below.

[00108] In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement one or more multiple channel access mechanisms, e.g., channel bonding and/or channel aggregation mechanisms, which may allow, for example, to increase a link bitrate and/or a link capacity, e.g., as described below.

[00109] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate one or more packets, for example, according to a packet structure, which may be configured to support at least communication by stations, for example, EDMG stations, e.g., according to a future IEEE 802.11ay Specification, as described below.

[00110] In some demonstrative embodiments, the packet structure may be configured, for example, to support stations, e.g., EDMG stations, using one or more EDMG channels, e.g., including two or more 2.16 GHz channels, for example, at least to reliably and/or efficiently perform one or more beamforming training operations of a beamforming training procedure, which may, for example, be a critical operation for millimeter-wave systems, e.g., as described below. [00111] In some demonstrative embodiments, one distinctive feature of wireless systems operating in a directional frequency band, e.g., frequencies above 45 GHz, is a beamforming mechanism, e.g., directional transmission and reception, which may be implemented, for example, to offset a large free-space path loss of millimeter- wave transmissions, e.g., according to the Friis transmission Law.

[00112] In some demonstrative embodiments, beamforming training mechanisms, e.g., in compliance with an IEEE 802.11-2016 Specification, may be used by a pair of stations, e.g., devices 102 and/or 140, to determine appropriate antenna settings, e.g., including one or more Antenna Weight Vectors (AWV), which may be configured for transmission and/or reception.

[00113] In some demonstrative embodiments, a beamforming training procedure may include, for example, a sector-level sweep (SLS), which may be mandatory, during which transmit beamforming training, e.g., coarse training, may be performed.

[00114] In some demonstrative embodiments, devices 102 and/or 140 may be configured to perform a Beamforming procedure (also refereed to as "beamforming training protocol") including a Sector level sweep (SLS) phase, e.g., including, for example, an Initiator Sector Sweep (ISS), which may include a sector sweep performed, for example, by a Beamforming initiator, and a Responder Sector Sweep (RSS), which may include a sector sweep performed, for example, by a Beamforming responder. The RSS may, for example, follow the ISS.

[00115] In some demonstrative embodiments, the beamforming training procedure may include, for example, a Beam Refinement Protocol (BRP) phase, which may be optional, and which may enable to perform receive beamforming training, and/or an iterative refinement of the AWV, e.g., of a transmitter and/or receiver at one or both stations.

[00116] In some demonstrative embodiments, devices 102 and 140 may be configured to perform a BRP, e.g., following the SLS phase.

[00117] Some demonstrative embodiments are described herein with respect to a BRP, which may be performed after a SLS phase of a beamforming procedure. However, in other embodiments, BRP may be performed as part of any other phase and/or procedure. [00118] In some demonstrative embodiments, devices 102 and 140 may exchange a plurality of BRP frames during the BRP. For example, device 102 may send one or more, e.g., a plurality of, BRP frames to device 140, and/or device 140 may send one or more, e.g., a plurality of, BRP frames to device 102. [00119] In some demonstrative embodiments, one of devices 102 and 140 may perform the functionality of a BRP initiator to initiate the exchange of BRP frames, and another one of devices 102 and 140 may perform the functionality of a BRP responder. In one example, device 102 may perform the functionality of the BRP initiator and/or device 140 may perform the functionality of the BRP responder. [00120] In some demonstrative embodiments, the BRP phase may include communication of one or more Tx-BRP packets, for example, including Training (TRN) sequences, which may be transmitted with different AWVs of a Tx station, e.g., device 102. For example, an Rx station, e.g., device 140, may use the same AWV in the reception of all TRN sequences, e .g., as described below. [00121] In some demonstrative embodiments, the BRP phase may include communication of one or more Rx-BRP packets, wherein, for example, all TRN sequences are transmitted with the same AWV by the Tx station. For example, the RX station may use different AWVs in the reception of the TRNs, e.g., as described below. [00122] In some demonstrative embodiments, the BRP may implement a beam tracking mechanism, which may allow, for example, ongoing refinement of an established beam link, e.g., during data traffic.

[00123] In some demonstrative embodiments, performing the SLS over a primary channel of a Basic Service Set (BSS), e.g., which may have a specified bandwidth of 2.16GHz, may enable, for example, ensuring backward compatibility with one or more "legacy" Specifications utilizing a single bandwidth channel, e.g., an IEEE 802.11-2016 Specification. However, beamforming training of a transmitter and/or a receiver performed in a single bandwidth channel, e.g., the 2.16GHz channel, may not necessarily be optimal, or may even not be satisfactory, for example, for transmissions, e.g., bonded transmissions, over a channel, for example, an EDMG channel, e.g., with a channel bandwidth of 4.32, 6.48, or 8.64 GHz, or any other channel BW including a plurality of channels, e.g., 2.16GHz channels. [00124] In some demonstrative embodiments, in some use cases, implementations and/or scenarios, for example, for beamforming training over multiple channels, it has been determined through simulation and/or measurement, that AWVs obtained for a given channel, e.g., a 2.16 GHz channel may not necessarily be useful for an adjacent channel, e.g., an adjacent 2.16 GHz channel; and/or that beamforming training, e.g., transmitter and/or receiver training, performed in a channel, e.g., a 2.16 GHz channel, may not necessarily be optimal, or even satisfactory, for a transmission over a channel BW including two or more channels, e.g., 2.16 GHz channels, e.g., over a channel bandwidth of 4.32, 6.48, or 8.64 GHz, which includes that same single BW channel, e.g., the same 2.16 GHz channel.

[00125] In some demonstrative embodiments, it may be advantageous to specify, for example, low-overhead frames and/or mechanisms, which may, for example, allow stations to perform beamforming training over single channels, e.g., 2.16 GHz channels, and/or channel BWs, e.g., bonded channels, including a plurality of channels, e.g., two or more 2.16 GHz channels.

[00126] In some demonstrative embodiments, beamforming training may be performed, for example, by using the SLS procedure or the BRP phase, e.g., as described above.

[00127] In some demonstrative embodiments, it may be advantageous to perform beamforming training over a channel BW including two or more 2.16 GHz channels by using the BRP protocol, e.g., instead of using SLS, for example, when performing channel bonding after the link has already been established through a primary channel. For example, the BRP protocol may be iterative and may be performed with a higher Modulation and Coding Scheme (MCS) than the SLS. [00128] In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive, access, and/or process a BRP packet, which may be configured according to BRP packet structure, which may be configured to support and/or enable stations, e.g., EDMG stations, to perform beamforming training, e.g., using a bonded signal bandwidth, for example, over a channel BW including two or more 2.16 GHz channels, e.g., as described below.

[00129] In some demonstrative embodiments, the BRP packet structure may provide a mechanism, which may at least specifically address one or more technical issues of beamforming training when a channel BW including two or more 2.16 GHz channels, e.g.,. with channel bonding, is used, e.g., as described below.

[00130] In some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive, access, and/or process a BRP packet, which may have a frame format, which may allow stations, e.g., EDMG stations, using an EDMG channel BW, e.g., a channel BW including two or more 2.16 GHz channels, to perform beamforming training over single bandwidth channels, e.g., 2.16 GHz channels, and over one or more wide channels and/or bonded channels, e.g., a wide channel including two or more 2.16 GHz channels, for example, even with transmission of a single frame, e.g., as described below.

[00131] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate one or more packets, for example, one or more BRP packets, according to a Physical Layer (PHY) Protocol Data Unit (PPDU) structure, for example, an EDMG PPDU structure, e.g., as described below. [00132] In some demonstrative embodiments, it may not be advantageous in some cases, deployments and/or scenarios, to utilize a first BRP frame for single, e.g., 2.16 GHz, channel transmission and a second ("bonded" or "wide") BRP frame for a channel BW including two or more channels, e.g., 2.16 GHz channels, in which the training (TRN) fields are transmitted over the entire signal bandwidth of the wide or bonded channel BW, e.g., as described below.

[00133] Reference is made to Fig. 2, which schematically illustrates a first structure 201 and a second structure 202 of a PPDU format, which may be implemented in accordance with some demonstrative embodiments. In one example, devices 102 and/or 140 (Fig. 1) may be configured to generate, transmit, receive and/or process one or more PPDUs, e.g., BRP PPDUs, according to PPDU structures 102 and/or 202, e.g., as described below.

[00134] For example, the PPDU structures 201 and 202 may be implemented by a BRP frame for beamforming training of a channel BW including two or more channels, e.g., 2.16 GHz channels. For example, PPDU structures 201 and 202 may be configured, for example, as an EDMG PPDU for a channel BW transmission including two 2.16 GHz channels. [00135] In some demonstrative embodiments, as shown in Fig. 2, PPDU structures 201 and/or 202 may be configured for communication over a channel BW including two channels denoted "channel N" and "channel N+l". For example, the channel BW may include two 2.16GHz channels. [00136] Some demonstrative embodiments are described with respect to a PPDU structure configured for communication over a channel BW including two channels, e.g., as shown in Fig. 2. However, in other embodiments, the PPDU structure may be configured for communication over any other number of channels.

[00137] In some demonstrative embodiments, as shown in Fig. 2, PPDU structures 201 and 202 may include a first portion 204 ("duplicate portion") including one or more fields to be transmitted by duplicating fields of portion 204 over the two channels, e.g., as described below.

[00138] In some demonstrative embodiments, as shown in Fig. 2, PPDU structures 201 and 202 may include a second portion 206 including one or more fields to be transmitted over the channel BW, e.g., the wide BW, including the two or more channels e.g., the two or more 2.16 GHz channels, as described below.

[00139] In some demonstrative embodiments, as shown in Fig. 2, structures 201 and/or 202 may be configured to utilize transmission in a duplicate mode of a non- EDMG (legacy) portion 216, and an EDMG Header A field 218. [00140] In some demonstrative embodiments, as shown in Fig. 2, structures 201 and/or 202 may be configured to utilize transmission of a data field of the EDMG PPDU in either a duplicate mode or a non-duplicate mode, e.g., as described below.

[00141] In one example, as shown in Fig. 2, structure 201 may include duplicate transmission of a data field 219 in duplicate mode, e.g., over each of the Channel N and the Channel N+l.

[00142] In another example, as shown in Fig. 2, structure 202 may include non- duplicate transmission of a data field 217, e.g., over a signal bandwidth of the wide channel BW including the Channel N and the Channel N+l.

[00143] In some demonstrative embodiments, as shown in Fig. 2, structures 201 and/or 202 may be configured to utilize transmission of one or more TRN and/or AGC fields 221 in a non-duplicate mode, e.g., over the signal bandwidth of the wide channel BW including the Channel N and the Channel N+1.

[00144] In some demonstrative embodiments, for example, according to one approach, if two stations, e.g., EDMG stations, would like to perform beamforming training over a plurality of single, e.g., 2.16 GHz, channels available, and a channel BW including two or more channels, e.g., two or more 2.16GHz channels, of the plurality of 2.16 GHz channels, the stations may perform beamforming training using a plurality of different channel accesses, for example, if different BRP frames are to be used to train each channel and/or channel combination, e.g., as described below. [00145] Reference is made to Fig. 3, which schematically illustrates a beamforming training procedure 300 , according to one approach, in accordance with some demonstrative embodiments.

[00146] For example, as shown in Fig. 3, beamforming training procedure 300 may be performed over two channels, e.g., 2.16 GHz channels, for example, to train the two channels and a channel BW, e.g., a bonded channel, including the two channels.

[00147] In one example, the beamforming training procedure 300 may provide an approach to perform beamforming training of two single, e.g., 2.16 GHz, channels, for example, including a primary channel, denoted "Channel N", and a secondary channel, denoted "Channel N+1", and a channel BW including the primary channel N and the secondary channel N+1.

[00148] In some demonstrative embodiments, as shown in Fig. 3, for example, beamforming training procedure 300 may include performing a first BRP phase 302 over the channel N, e.g., during a first channel access, followed by a second BRP phase 304 over the channel N+1, e.g., during a second channel access, followed by a third BRP phase 306 over the channel BW including the channels N and N+1, e.g., during a third channel access.

[00149] In some demonstrative embodiments, for example, as shown in Fig. 3, BRP frames communicated during BRP phases 302, 304 and/or 306 may include one or more training (TRN) fields 309. [00150] In some demonstrative embodiments, as shown in Fig. 3, in BRP phases 302 and 304, a BRP frame configured for a single, e.g., 2.16 GHz, channel may be used; and/or for the BRP phase 306, the BRP frame may have a PPDU format configured to perform beamforming training over the plurality of channels, e.g., according to PPDU structure 201 and/or PPDU structure 202 (Fig. 2).

[00151] In some demonstrative embodiments, the beamforming training procedure 300 may be relatively simple, may not require substantial changes to an IEEE 802.11ay mechanism, and/or may allow a feedback to be obtained for each channel. However, in some use cases, deployments, and/or scenarios, beamforming training procedure 300 may be time consuming, may have a relatively large overhead, e.g., using three BRP phases 302, 304 and 306, and/or may require different and/or separate channel accesses, e.g., for each BRP phase of BRP phases 302, 304 and/or 306.

[00152] Referring back to Fig. 1, in some demonstrative embodiments, devices 102 and/or 140 may be configured to generate, transmit, receive, access, and/or process a BRP packet, which may have a BRP packet structure configured to include training (TRN) fields, which may allow, for example, beamforming training over single channels, e.g., single 2.16 GHz channels, as well as over one or more EDMG channels, a wide channel including two or more 2.16 GHz channels, for example, even during transmission of a single BRP frame, e.g., as described below.

[00153] In some demonstrative embodiments, the BRP frame may be used, for example, to estimate the antenna weight vectors (AWVs), e.g., of both a transmitter and a receiver, for example, for one or more 2.16 GHz channels, and/or one or more possible channel BW configurations of two or more channels, for example bonded channels, e.g., as described below.

[00191] In one example, the plurality of 2.16 GHz channels may include a first 2.16GHz channel, a second 2.16GHz channel, and a third 2.16 GHz channel. According to this example, the first channel BW may include, for example, the first and second 2.16 GHz channels, and/or the second channel BW may include the first and third 2.16 GHz channels.

[00192] In some demonstrative embodiments, a count of 2.16 GHz channels in the first combination may be different from a count of 2.16 GHz channels in the second combination, e.g., as described below.

[00193] In one example, the plurality of 2.16 GHz channels may include a first 2.16GHz channel, a second 2.16GHz channel, and a third 2.16 GHz channel. According to this example, the first channel BW may include, for example, the first, second, and third 2.16 GHz channels, and/or the second channel BW may include, for example, the first and third 2.16 GHz channels.

[00196] In some demonstrative embodiments,, for example, the BRP frame may be configured, for example, to enable beamforming training of at least three 2.16 GHz channels, e.g., denoted N, N+l, and N+2; and some or all combinations of channel BWs including the three 2.16 GHz channels.

[00204] In one example, a STA, e.g., device 102, may be configured to make a request to a peer STA, e.g., device 140, for example, to indicate a need and/or a request to perform beamforming training by using the BRP frame with a particular TRN configuration. For example, a sequence of control bits, e.g., BRP_REQUESTED bits, BRP_CONFIGURATION_REQUESTED bits, and/or any other bits and/or fields, may be set in a control frame, e.g., a Grant frame or any other frame, to define a BRP configuration to be used.

[00205] In some demonstrative embodiments, device 140 may receive the BRP frame including the PHY header including the indication of the at least one channel BW.

[00206] In some demonstrative embodiments, controller 154 may control, cause and/or trigger device 140 to receive the indication of the at least one channel BW.

[00207] In some demonstrative embodiments, an RX station, e.g., device 140, may be configured to feedback to a TX station, e.g., device 102, beamforming training-related information, for example, for each trained channel, for example, for each channel "covered" by the received BRP packet, e.g., which may have a bandwidth of 2.16, 4.32, 6.48, or 8.64 GHz, or any other bandwidth.

[00209] In some demonstrative embodiments, device 140 may be configured to process the first plurality of TRN fields over two or more of the plurality of 2.16 GHz channels simultaneously. For example, device 140 may include two or more RF chains to process reception over the two or more of the plurality of 2.16 GHz channels, for example, an RF chain per a 2.16 GHz channel, e.g., as described below.

[00210] Reference is made to Fig. 4, which schematically illustrates a BRP frame structure 400, in accordance with some demonstrative embodiments.

[00211] In some demonstrative embodiments, devices 102 and 140 (Fig. 1) may be configured to generate, transmit, receive and/or process one or more BRP frames according to the structure of BRP frame 400, for example, to communicate a BRP frame to train a channel BW over a plurality of channels, e.g., 2.16GHz channels. [00212] In some demonstrative embodiments, as shown in Fig. 4, BRP frame 400 may include a first plurality of TRN fields 402 configured for beamforming over two channels, e.g., 2.16 GHz channels, denoted "channel N" and "channel N+l".

[00213] In one example, BRP frame 400 may be configured for simultaneous transmission and reception of the first plurality of TRN fields over two or more of the plurality of 2.16 GHz channels, e.g., as described below.

[00214] In some demonstrative embodiments, as shown in Fig. 4, BRP frame 400 may include a second plurality of TRN fields 412 configured for beamforming over a channel BW including the channel N and the channel N+l.

[00215] In some demonstrative embodiments, as shown in Fig. 4, the first plurality of TRN fields 402 may include a first plurality of Tx sector TRN sequences 404, e.g., including Nt Tx sector TRN sequences, denoted "Tx sector 1 "- "Tx sector Nt", corresponding to a respective plurality of Tx sectors of a TX wireless station, e.g., device 102 (Fig. 1), which is to transmit BRP frame 400, e.g., wherein Nt denotes a count of the Tx sectors of the Tx wireless station. [00216] In some demonstrative embodiments, as shown in Fig. 4, a Tx sector TRN sequence 404 may include a plurality of repetitions of an Rx sector TRN sequence 406, e.g., including Nr Rx sector TRN sequences, denoted "RX sector 1 "- "Rx sector Nr", corresponding to a plurality of RX sectors of a receiver station, e.g.,. device 140 (Fig. 1), to receive BRP frame 400, e.g., wherein Nr denotes a count of the Rx sectors of the receiver wireless station.

[00218] In some demonstrative embodiments, as shown in Fig. 4, a Tx sector TRN sequence 414 may include a plurality of repetitions of Rx sector TRN sequence 416, , e.g., including Nr Rx sector TRN sequences, denoted "RX sector 1 "- "Rx sector Nr", corresponding to the plurality of RX sectors of the receiver station.

[00219] In some demonstrative embodiments, as shown in Fig. 4, TRN fields 402 and 412 may be configured to allow for beamforming training over one or more underlying 2.16 GHz channels, and/or over a channel BW including a plurality of 2.16GHz channels.

[00220] In some demonstrative embodiments, BRP frame 400 may allow, for example, for beamforming training to be performed over a 2.16 GHz channel, e.g., Channel N or Channel N+l, and, for example, followed by, beamforming training over the channel BW including the channels N and N+l, for example, even by using a single BRP frame and one channel access.

[00221] In some demonstrative embodiments, as shown in Fig, 4, the order of the TRN fields in the BRP frame 400 may include the TRN fields 402 for the single channels, followed by the TRN fields 412 for the wide channel BW including the channels N and N+l, for example, to support beamforming training to be performed first for a single BW channel, e.g., a 2.16 GHz channel, and then for a channel BW including two or more of the "single BW" channels, e.g., 2.16 GHz channel.

[00222] In other embodiments, the order of the TRN fields 402 and 412 in the BRP frame 400 may be reversed, for example, to include the TRN fields 412 for the channel BW including the plurality of channels, followed by the TRN fields 402 for the 2.16 GHz channel, for example, to support beamforming training to be performed first for the channel BW, and then for the 2.16 GHz channels.

[00223] In some demonstrative embodiments, for a 2.16 GHz channel, e.g., for each intended channel, the BRP frame 400 may allow for both TX and RX training. [00224] For example, as shown in Fig. 4, for a Tx sector 404, e.g., for each TX sector "tested" (i < TX sector < Nt), Nr RX sectors 406 may also be "tested", for example, by transmitting a pre-defined number of TRN fields 402, e.g., three TRN fields 402 or any other number of fields, e.g., in each combination of a TX sector and an RX sector.

[00225] In some demonstrative embodiments, a similar process of simultaneously training TX and RX sectors may be performed for a channel BW including the plurality of 2.16GHz channels.

[00226] For example, as shown in Fig. 4, for a Tx sector 414, e.g., for each TX sector "tested" (i < TX sector < Nt), Nr RX sectors 416 may also be "tested", for example, by transmitting a pre-defined number of TRN fields 412, e.g., three TRN fields 412 or any other number of fields, e.g., in each combination of a TX sector and an RX sector.

[00227] In some demonstrative embodiments, as shown in Fig. 4, the TRN fields 402 may be transmitted simultaneously, e.g., in duplicate mode, over the channel N and the channel N+l, for example, if a receiver, e.g., device 140 (Fig. 1), is configured to simultaneously process TRN fields 402 over the channel N and the channel N+l. [00228] In some demonstrative embodiments, a BRP frame structure may be configured, for example, to support some receiver implementations, which may not be able to process received TRN fields of multiple channels simultaneously, for example, if the receiver includes only one RF chain, e.g., as described below.

[00230] In some demonstrative embodiments, device 102 may transmit, e.g., in duplicate mode, the first plurality of TRN fields of the BRP frame over two or more of the plurality of 2.16 GHz channels sequentially, for example, to enable the receiver to perform beamforming over the plurality of 2.16 GHz channels e.g., as described below.

[00231] In some demonstrative embodiments, device 140 may be configured to process the first plurality of TRN fields of the BRP frame over two or more of the plurality of 2.16 GHz channels sequentially. For example, device 140 may process reception over a single 2.16 GHz channel, for example, even if device 140 includes a single RF chain, e.g., as described below.

[00232] In some demonstrative embodiments, controller 124 may be configured to control, cause, and or trigger device 102 to transmit a plurality of repetitions of the first plurality of Tx sector TRN sequences 404 (Fig. 4), e.g., as described below.

[00234] In some demonstrative embodiments, a count of the plurality of repetitions of the first plurality of Tx sector TRN sequences may be based, for example, on a count of the plurality of 2.16GHz channels, e.g., which may form the channel BW, as described below.

[00244] In some demonstrative embodiments, BRP frame 500 may allow, for example, for beamforming training to be performed sequentially, e.g., first over one of Channel n and Channel n+1, and then over another one of Channel n and Channel n+1; and, for example, followed by, beamforming training over the channel BW including the channels N and N+1, for example, even by using a single BRP frame and one channel access.

[00245] In some demonstrative embodiments, as shown in Fig. 5, "duplicate" TRN fields, e.g., in repetitions 503, may be transmitted over the plurality of 2.16 GHz channels at the same time.

[00246] In some demonstrative embodiments, as shown in Fig. 5, the repetitions 503 of TRN fields 502 may be duplicated Nchannel times, for example, wherein Nchannel denotes the count of single BW channels in which beamforming training is to be performed. [00247] For example, as shown in Fig. 5, duplicate TRNs 502 may be transmitted in two "time intervals", e.g., two repetitions 503, for example, each including a repetition of the transmission from the "TX sector 1" to the "TX sector Nt".
