[0084] 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.

[0085] 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.

[0086] 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. Had Specification.

[0087] 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. Hay Standard, which may be, for example, configured to enhance the efficiency and/or performance of an IEEE 802.1 lad Specification, which may be configured to provide Wi-Fi connectivity in a 60 GHz band.

[0088] Some demonstrative embodiments may enable, for example, to significantly increase the data transmission rates defined in the IEEE 802.1 lad 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. Luusyj 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.

[0090] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate MIMO communications over the mmWave wireless communication band.

[0091] 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. Hay Standard and/or any other standard and/or protocol. [0092] 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. [0093] 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.

[0094] 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.

[0095] 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. [0096] 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.

[0097] 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 \JL M1MU transmissions and/or UL MEVIO transmissions, for example, for communicating over the NG60 and/or EDMG networks.

[0098] 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-MIMO scheme, e.g., a DL MU-MIMO, or any other MU scheme.

[0099] 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. Had Specification or any other scheme, for higher data rates and/or increased capabilities, e.g., as described below.

[00100] 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 bonded channels. [00101] In some demonstrative embodiments, the channel bonding mechanisms may include, for example, a mechanism and/or an operation whereby two or more 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 bonded channel, however other embodiments may be implemented with respect to communications over a channel bandwidth, e.g., a "wide" channel, including or formed by two or more channels, for example, an aggregated channel including an aggregation of two or more channels.

[00102] 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.

[00103] 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.

[00104] In some demonstrative embodiments, the multiple channel access mechanisms may be configured to provide, for example, one or more levels, e.g., all levels, of clear channel assessment (CCA), e.g., a physical CCA and/or a virtual CCA, for example, to one or more stations, e.g., all stations, that are active over the channels, e.g., including stations that belong to different basic service sets (BSS), and/or legacy stations, e.g., DMG stations, that are not aware of multiple channel access.

[00105] In some demonstrative embodiments, a multiple channel access protocol may be configured to utilize a legacy preamble, which may be sent in all channels allocated for multiple channel access; and/or legacy Request to Send (RTS) and/or Clear to Send (CTS) frames, which may be exchanged, for example, in a "duplicated mode", for example, over all channels intended for multiple channel data transaction.

[00106] In some demonstrative embodiments, a technical problem to be addressed, for example, to allow efficient use of multiple channels, may be communication of information to allow negotiating and/or using only channels that are not occupied, e.g., among all channels that the communication stations support. Communicating this information by RTS/CTS frames may allow an efficient and/or preferred approach, for example, at least since this approach may allow keeping backward compatibility with legacy stations, e.g., DMG stations in accordance with an IEEE 802.11-2016 Specification.

[00107] In some use cases, scenarios and/or implementations, it may not be advantageous to implement a solution, which allocates two bits of a scrambler seed field to identify each bonded channel as a unique combination of a primary channel placement and secondary channels. Specifically, such a solution may be limited, as it only allows identification of four values, e.g., of channel BW, which may only allow very specific and/or limited channel bonding configurations.

[00108] In one example, a negotiation of channel bandwidth between a Transmit Opportunity (TXOP) initiator and a TXOP responder may be limited with respect to four 20 MHz channels, e.g., of a non-directional frequency band, e.g., in compliance with an IEEE 802.1 lac Specification.

[00109] For example, the negotiation may allow a selection only from 4x20MHz channel 42, a single 2x20MHz channel 40, and a single 20MHz channel 40, e.g., as follows:

Table 1

[00110] In some demonstrative embodiments, a channel bandwidth negotiation scheme, for example, a channel bonding negotiation scheme, e.g., which may be suitable for implementation in a future IEEE 802. Hay Specification and/or any other Specification and/or protocol, may support a plurality of combinations, e.g., even any combination, of secondary channels around a known primary channel.

[00111] In some demonstrative embodiments, a multi-channel communication scheme may be configured, for example, for communication in a directional frequency band, for example, a frequency band above 45GHz, e.g., a 60GHz frequency band, for example using a total of up to four channels, e.g., four 2.16GHz channels.

[00112] In some demonstrative embodiments, the multi-channel communication scheme may be configured, for example, for communication in a directional frequency band, for example, a frequency band above 45GHz, e.g., a 60GHz frequency band, for example using a total of more than four channels, e.g., six or more 2.16GHz channels. [00113] In some demonstrative embodiments, the multi-channel communication scheme may be configured to support a 4x2.16 GHz channelization, e.g., as described below. In other embodiments, the multi-channel communication scheme may be configured to support a channelization of channel bandwidth including any other number of 2.16GHz channels, e.g., more than four 2.16GHz channels. [00114] In other embodiments, the multi-channel communication scheme may be configured to support any other channelization scheme of any other number and/or width of channels.

[00115] In some demonstrative embodiments, a multi-channel communication scheme may be configured to support negotiation of two types of multi-channel access, for example, channel bonding and/or channel aggregation, e.g., as described below. [00116] In one example, a multi-channel communication scheme, e.g., for 4x2.16 MHz channelization in a directional frequency band, may support, for example, negotiation of channel bonding and/or channel aggregation for a plurality of channel bandwidth, for example, including some or all of the following channel bandwidths: Bandwidth

(GHz)

1 1x2.16 1 2 3 4

Primary

2 2x2.16 9 NA NA bonding and/or

aggregation

3 2x2.16 NA 10 NA

4 3x2.16 17 NA

5 3x2.16 NA 18

6 4x2.16 25

7 2x2.16 2 4 aggregation

Table 2

[00117] In some demonstrative embodiments, according to Table 2, there may be a plurality of configurations for 4x2.16 MHz channelization in a directional frequency band.

[00118] In one example, the channelization may support at least one variant of a 2.16GHz channel bandwidth, e.g., according to line 1 of Table 2.

[00119] In one example, according to lines 2-6 of Table 2, channel bonding may support at least one 4x2.16GHz channel bandwidth, e.g., channel number 25 according to line 6 of Table 2; two variants of 3x2.16GHz channel bandwidths, e.g., channel number 17 according to line 4 of Table 2 and/or channel number 18 according to line 5 of Table 2; and/or two variants of 2x2.16GHz channel bandwidths, e.g., channel number 10 according to line 3 of Table 2 and/or channel number 9 according line 2 of Table 2.

[00120] In one example, wider channel bandwidths, e.g., according to lines 2-6 of Table 2, may also be configured for aggregation, and/or a wide channel bandwidth may be configured for aggregation, e.g., according to line 7 of Table 2.

[00121] In some demonstrative embodiments, devices 102 and/or 140may be configured to support communication over some or all of the channel bandwidths of Table 2, and/or or over one or more additional or alternative channel bandwidths.

[00122] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate information, for example, to signal one or more of the channel configurations of Table and/or one or more additional or alternative channel configurations over a directional frequency band, e.g., as described below.

[00123] In some demonstrative embodiments, devices 102 and/or 140 may be configured to signal a priori information about a primary channel placement and maximum supported channel width, for example, in conjunction with information included in RTS/CTS frames, for example, to indicate a valid channel that belongs to an advertised primary channel and channel width, e.g., as described below.

[00124] In some demonstrative embodiments, one or more fields in one or more control frames, e.g., DMG control frames and/or EDMG control frames, may be implemented to signal bandwidth information of a channel over a directional frequency band, e.g., as described below.

[00125] In some demonstrative embodiments, a limited space in DMG control frames may be utilized to cover as many configurations as possible of channel bonding and/or aggregation types, for example, to indicate channel bandwidth during RTS/CTS negotiation for multiple channel access in EDMG networks, e.g., as described below. [00126] In some demonstrative embodiments, devices 102 and/or 140 may utilize one or more fields in a control Physical Layer (PHY) header, for example, for channel bandwidth encoding of DMG control frames, e.g., as described below.

[00127] In some demonstrative embodiments, devices 102 and/or 140 may be configured to signal channel bandwidth over a directional frequency band, for example, according to a channel bandwidth encoding scheme, e.g., as described below.

[00128] In some demonstrative embodiments, devices 102 and/or 140 may utilize the one or more fields in the PHY header, for example, to indicate a channel BW and/or to indicate one or more 2.16 GHz channels to form the channel BW, e.g., as described below.

[00130] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 and/or message processor 128 to generate a PHY Protocol Data Unit (PPDU).

[00131] In some demonstrative embodiments, the PPDU may include an EDMG PPDU. [00132] In some demonstrative embodiments, the PPDU may include a control mode PPDU.

[00133] In some demonstrative embodiments, the PPDU may include an RTS frame or a CTS frame. LUU 1 J J in some demonstrative embodiments, the PPDU may include any additional or alternative type of control mode PPDU.

[00135] In some demonstrative embodiments, the PPDU may include any additional or alternative type of PPDU. [00136] In some demonstrative embodiments, the PPDU may include a PHY header, e.g., as described below.

[00137] In some demonstrative embodiments, the PHY header may include a non-EDMG header (L-header) field.

[00138] In some demonstrative embodiments, the PHY header, e.g., the L-header, may include a scrambler initialization field including a plurality of bits to indicate a channel BW field value.

[00139] In some demonstrative embodiments, the channel BW field value may indicate a channel BW and one or more 2.16 Gigahertz (GHz) channels to form the channel BW, e.g., as described below.

[00140] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 and/or transmitter 118 to transmit, e.g., to device 140, one or more fields of the PPDU over the channel BW in a directional frequency band.

[00146] In some demonstrative embodiments, the plurality of bits indicating the channel BW field value may include three bits, e.g., as described below. LUU 147J in otner embodiments, the plurality of bits indicating the channel BW field value may include any other number of bits, e.g., more than three bits.

[00148] In some demonstrative embodiments, the scrambler initialization field of the PPDU may include a bit BO with the value 1, and bits Bl, B2, and B3 to indicate the channel BW field value, e.g., as described below.

[00149] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 to set the BW field value to 0, for example, when the one or more fields of the PPDU are to be transmitted over a 2.16GHz channel BW including one 2.16GHz channel, e.g., as described below.

[00152] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 to set the BW field value to 1 or 2, for example, when the one or more fields of the PPDU are to be transmitted over a 4.32GHz channel BW including two contiguous 2.16GHz channels, e.g., as described below.

[00156] In some demonstrative embodiments, device 140 may receive the PPDU over the 6.48GHz channel BW. LUU 1 5 /J in some demonstrative embodiments, controller 154 may control, cause and/or trigger device 140 to receive the one or more fields of the PPDU over the 6.48GHz channel BW including the three contiguous 2.16GHz channels, for example, when the BW field value is 3 or 4.

[00158] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 to set the BW field value to 5, for example, when the one or more fields of the PPDU are to be transmitted over a 8.64GHz channel BW including four contiguous 2.16GHz channels, e.g., as described below.

[00162] In some demonstrative embodiments, device 140 may receive the PPDU over the channel BW including the two non-contiguous channels.

[00163] In some demonstrative embodiments, controller 154 may control, cause and/or trigger device 140 to receive the one or more fields of the PPDU over the channel BW including the two non-contiguous channels, for example, when the BW field value is 6 or 7.

[00164] In some demonstrative embodiments, controller 124 may control, cause and/or trigger device 102 to set each of reserved bits 22 and 23 of the PHY header to "1".

[00165] In one example, one or more reserved bits, e.g., reserved bits 22 and 23, in the control PHY header may be defined to be set to a predefined value, for example, "11", e.g., to indicate that a Scrambler Initialization field is to be used, e.g., to signal the channel BW.

[00166] Reference is made to Fig. 2, which schematically illustrates a structure of a scrambler initialization field 200, in accordance with some demonstrative embodiments. LUUib /j in some demonstrative embodiments, as shown in Fig. 2, when both reserved bits 22 and 23 of a PHY header of a PPDU are each set to "1", and a bit BO includes the value of "1", the bits Bl, B2, and/or B3 may be used to indicate the channel bandwidth to communicate the PPDU, e.g., as described above. [00168] In some demonstrative embodiments, device 102 (Fig. 1) may transmit a PPDU including scrambler initialization field 200 to device 140 (Fig. 1), for example, to indicate the channel BW and the one or more 2.16 GHz channels that form the channel BW to communicate the PPDU.

[00169] Referring back to Fig. 1, in some demonstrative embodiments, devices 102 and 140 may use a priori information, for example, to indicate the one or more 2.16GHz channels that form the channel BW.

[00170] In some demonstrative embodiments, the one or more channels may include one or more channels of a sequence of four channels denoted N, N+l, N+2, and N+3.

[00171] In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate information, for example, to signal channel configurations of one or more of the sequence of four channels N, N+l, N+2, and/or N+3.

[00172] In some demonstrative embodiments, a device, e.g., device 140, that receives scrambler initialization field in a header of a PPDU, may be able to determine the one or more channels that form the channel BW to be used to communicate one or more fields of the PPDU, e.g., as described below.

[00173] In some demonstrative embodiments, a device, e.g., device 140 may determine the one or more channels that form the channel BW, for example, based on a channel over which the PPDU is transmitted, e.g., as described below.

[00174] In some demonstrative embodiments, the device may determine the one or more channels that form the channel BW, for example, based on a criterion corresponding to a relation between the channel over which the PPDU is transmitted and the one or more channels that form the channel BW, e.g., as described below.

[00175] In some demonstrative embodiments, the criterion may include a location of the channel with respect to the one or more channels that form the channel BW, e.g., as described below. [00176] In one example, the channel BW may be determined, for example, based on a lowest channel of the four channels N, N+l, N+2, and N+3, over which the PPDU is transmitted, e.g., as described below. LUU 177J in some demonstrative embodiments, the criterion may include a primary channel placement, e.g., as described below.

[00178] In some demonstrative embodiments, a priori information about a primary channel placement and a maximum supported channel width may be used in conjunction with information included in RTS/CTS frames, for example, to indicate a valid channel that belongs to an advertised primary channel and channel width, e.g., as described below.

[00179] In some demonstrative embodiments, devices 102 and/or 140 may be configured to signal channel bandwidth over a directional frequency band, for example, according to a first channel bandwidth encoding scheme (also referred to as "option 1"), e.g., as described below.

[00182] For example, the notation "P" may denote a primary channel, the notation "u" may denote a channel is to be used as part of the channel BW, and the notation "NA" may denote a channel is not to be in use as part of the channel BW.

[00183] For example, the values of the bits Bl, B2, and/or B3 may be set, for example, according to Table 3, to support signaling of a Channel Bandwidth indication for channel bonding and/or channel aggregation, for example, for a channel bandwidth of up to 4x2.16GHz.

[00186] In some demonstrative embodiments, the second channel bandwidth encoding scheme may be configured to use the bit fields Bl, B2, and B3 to indicate a desired channel bandwidth of a signal, for example, with a maximum bandwidth of 3x2.16GHz, e.g., as follows:

Table 4

[00187] For example, according to Table 4, four codes may be used for indication of a bonded channel bandwidth, for example, to provide a Channel Bandwidth indication of channel bonding, e.g., for 3x2.16GHz maximal bandwidth.

[00188] In some demonstrative embodiments, four additional or alternative codes may be used for bandwidth indication of aggregated channels, e.g., as follows: B22, Number of 2.16 GHz channel Channel BW indication

[00190] For example, according to this encoding scheme each combination of primary channel and one of the secondary channels may be uniquely identified.
