[0096] In other embodiments, controller 174, message processor 178 and/or radio 164 may be implemented by one or more additional or alternative elements of device 160.

[0097] In some demonstrative embodiments, wireless communication devices 102, 140, 160 and/or 180 may form, or may communicate as part of, a wireless local area network (WLAN).

[0098] In some demonstrative embodiments, wireless communication devices 102, 140, 160 and/or 180 may form, or may communicate as part of, a WiFi network. [0099] In other embodiments, wireless communication devices 102, 140, 160 and/or 180 may form, and/or communicate as part of, any other additional or alternative network.

[00100] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to perform one or more operations, functionalities and/or communications according to a Multi AP Channel Bonding (MACB) scheme, e.g., as described below.

[00101] In some demonstrative embodiments, for example, an MACB transmission technique may be implemented, for example, to provide one or more technical benefits for wireless communication.

[00102] In one example, the MACB transmission technique may be implemented, for example, to provide a technical benefit of improving throughput performance of Cell Edge (CE) stations (STAs).

[00103] In some demonstrative embodiments, an MACB scheme may be configured, for example, to allow to coordinate multiple APs to transmit downlink (DL) data packets to a STA, e.g., a CE STA, for example, over multiple channels, for example, over multiple adjacent 20 MHz channels, for example, to provide an increased aggregate DL physical data rate to the CE STA, e.g., as described below.

[00104] Some demonstrative embodiments are described herein with respect to an MACB scheme configured with respect to a plurality of adjacent 20MHZ channels, for example, four adjacent 20MHz channels. However, in other embodiments, the MACB scheme may be configured with respect to any other configuration of channels, e.g., any other number of channels, any other bandwidth of channels, and/or any other plan or arrangement of the channels. [00105] Reference is made to Fig. 2, which schematically illustrates a Multi Access Point Channel Bonding (MACB) scheme 200, which may be implemented in accordance with some demonstrative embodiments.

[00106] In some demonstrative embodiments, for example, as shown in Fig. 2, the MACB scheme may be implemented for communication with a STA 240, denoted STA0, e.g., a CE STA, which may be associated with multiple APs, e.g., including a first AP 202, denoted "AP0", a second AP 260, denoted "API", a third AP 262, denoted "AP2", and/or a fourth AP 264, denoted AP3. [00107] In some demonstrative embodiments, the MACB scheme 200 may implement a definition of a master AP, e.g., AP 202, and one or more secondary APs, e.g., APs 260, 262, and/or 264, which may coordinate to serve the CE STA 240.

[00108] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP 202; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 260, 262, and/or 264.

[00109] In some demonstrative embodiments, when the master AP 202and/or the secondary APs, e.g., APs 260, 262, and/or 264, have data to transmit to the CE STA 240, the master AP 202, the secondary APs, e.g., APs 260, 262, and/or 264, and the CE STA 240 may perform one or more operations and/or communications to implement an MACB transmission, e.g., as described below. [00110] In some demonstrative embodiments, for example, the CE STA 240, may be equipped with multiple receiver chains and may be able to process multiple asynchronous data streams 212 from the multiple APs, e.g., APs 202, 260, 262, and/or 264, over non-overlapping channels in parallel.

[00111] In some demonstrative embodiments, for example, a receiver chain of the CE STA 240 over a channel, e.g., each channel, may be able to remove the interference from adjacent channels, for example, with either analog or digital domain band pass filter and/or according to any other additional or alternative interference mitigation techniques.

[00112] In some demonstrative embodiments, for example, if the CE STA 240 cannot sufficiently remove the interference from adjacent channels, the CE STA 240 may refrain from using the channel, for example, until the interference disappears.

[00113] Reference is made to Fig. 3, which schematically illustrates an MACB data transmission 300, which may be implemented in accordance with some demonstrative embodiments. [00114] In some demonstrative embodiments, for example, as shown in Fig. 3, MACB data transmission 300 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", and a fourth AP, denoted "AP3", and a STA, denoted STAO, e.g., a CE STA, which may be associated with the multiple APs.

[00115] In some demonstrative embodiments, the MACB scheme 200 may implement a definition of a master AP, e.g., the AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STAO.

[00116] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3.

[00117] In one example, MACB data transmission 300 may be over an 80MHz channel BW 308 including first, second, third, and fourth 20 MHz channels.

[00118] In some demonstrative embodiments, as shown in Fig. 3, the 80 MHz channel 308 may include a primary 20MHZ channel 310 including the first 20 MHz channel, and two secondary channels, a first 20MHZ secondary channel 312 including the second 20 MHz channel, and a second 40MHZ secondary channel 314, e.g., including the third and fourth 20MHZ channels.

[00119] In one example, CE STA 240 (Fig. 2) and APs 202, 260, 262 and/or 264 (Fig. 2) may communicate MACB data transmission 300, for example, according to MACB scheme 200 (Fig. 2).

[00120] In some demonstrative embodiments, the master AP (AP0) may sense one or more secondary channels of the AP, for example, during an interval of A Point Coordination Function (PCF) Interframe Space (PIFS) time or any other time, immediately preceding its backoff expiration or the start of the TXOP, and may decide on a TX channel bandwidth.

[00121] In one example, the phrase "secondary channels" may relate to secondary channels of the master AP. For example, one or more of, e.g., all, the coordinated APs, such as API, AP2 and AP3, may have a different primary channel and different secondary channels from the master AP.

[00122] In one example, secondary 20 MHz channel 312 and the secondary 40 MHz channel 314 may be idle. According to this example, the master AP (AP0) may send four duplicated 20 MHz MACB request-to-send (MACB-RTS) frames 320 to the CE- STA.

[00123] In some demonstrative embodiments, for example, the CE STA, e.g., the receiver of the MACB-RTS frames 320, may monitor its Clear Channel Assessment (CCA), for example, over the entire 80 MHz channel 308, for a predefined time period, for example, a PIFS time or any other time, prior to, the reception of the MACB-RTS frame 320.

[00124] In some demonstrative embodiments, for example, the STA may monitor the CCA, for example, over the entire 80 MHz channel 312, for a predefined time period, for example, a Short Interframe Space (SIFS) time 321 or any other time, after the reception of the MACB-RTS frame 320.

[00125] In some demonstrative embodiments, for example, the STA may transmit one or more trigger frames (MACB -TRIGGER) 322, for example, only over the channels, which are idle, e.g., over channels 310, 312 and/or 314. [00126] In some demonstrative embodiments, for example, if the STA does not detect interference on any of the secondary channels 312 and/or 314, e.g., PIFS prior to and SIFS after, the reception of the MACB-RTS frame 320, the STA may transmit four duplicate 20 MHz MACB -TRIGGER frames 322 to all coordinated APs, e.g., APs 0- 3. [00127] In some demonstrative embodiments, for example, if the STA detects interference on the secondary 20 MHz channel 312, e.g., PIFS prior to or SIFS after, the reception of the MACB-RTS frame 320, the STA may only transmit a 20MHz MACB -TRIGGER frame 322 to the master AP.

[00128] In some demonstrative embodiments, for example, if the STA detects interference on the secondary 40 MHz channel 314, e.g., PIFS prior to or SIFS after, the reception of the MACB-RTS frame 320, the STA may only transmit two duplicate 20 MHz MACB -TRIGGER frames 322 over the primary and secondary 20MHz channels 310 and 312 to two of the coordinated APs, e.g., to APs 0-1).

[00129] In some demonstrative embodiments, for example, as shown in Fig. 3, it may be assumed that there is no interference over the secondary channels 312 and/or 314, e.g., as described below. [00130] In some demonstrative embodiments, for example, as shown in Fig. 3, a SIFS time 321 or any other time, after the reception of the MACB-RTS frame 320, the STA, e.g., the receiver of the MACB-RTS frame 320, may transmit four duplicated 20 MHz MACB -TRIGGER frames 322 to all the coordinated APs, e.g., including the master AP and all secondary APs, e.g., APs 0-3. The MACB-trigger frame 322 may include, for example, specific information to parameterize the DL MACB data transmission.

[00131] In some demonstrative embodiments, as shown in Fig. 3, for example, a SIFS time 323 or any other time, after the reception of the MACB-TRIGGER frame 322, all the coordinated APs, which are identified in the MACB-TRIGGER frame 322, may transmit data packets 324 to the STA over each of the 20 MHz channels, e.g., simultaneously.

[00132] In some demonstrative embodiments, as shown in Fig. 3, for example, a SIFS time 325 or any other time, after the reception of the data packets 324 from all the coordinated APs, e.g., from APs 0-3, the STA, e.g., the receiver of the data packets 324, may transmit a feedback block acknowledge (BA) frame 326, for example, over each of the 20 MHz channels of the 80MHz channel 308.

[00133] In some demonstrative embodiments, the MACB scheme 300 may be configured to address one or more technical aspects, for example, to support efficient transmission, for example, even in cases that one or more of the secondary channels are busy, e.g., as described below.

[00134] In some demonstrative embodiments, for example, if a secondary 20 MHz channel is busy, e.g., as described below with reference to Fig. 4, both the secondary 20 MHz channel and a secondary 40 MHz are busy, e.g., as described below with reference to Fig. 5, or the secondary 20MHz channel is idle and the secondary 40 MHz channel is busy e.g., as described below with reference to Fig. 6, then the master AP (AP 0) may transmit the MACB-RTS only over some of the channels, e.g., as described below.

[00135] Reference is made to Fig. 4, which schematically illustrates an MACB transmission 400 to illustrate one or more technical aspects, which may be addressed in accordance with some demonstrative embodiments. [00136] In some demonstrative embodiments, for example, as shown in Fig. 4, MACB data transmission 400 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", and a fourth AP, denoted "AP3", and a STA, denoted STAO, e.g., a CE STA, which may be associated with the multiple APs.

[00137] In some demonstrative embodiments, MACB data transmission 400 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STAO.

[00138] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3. [00139] In one example, MACB data transmission 400 may be over an 80MHz channel 408 BW including first, second, third, and fourth 20 MHz channels.

[00140] In some demonstrative embodiments, as shown in Fig. 4, the 80 MHz channel 408 may include a primary 20MHZ channel 410 including the first 20 MHz channel, and two secondary channels, a first 20MHZ secondary channel 412 including the second 20 MHz channel, and a second 40MHZ secondary channel 414, e.g., including the third and fourth 20MHZ channels.

[00141] In one example, CE STA 240 (Fig. 2) and APs 202, 260, 262 and/or 264 (Fig. 2) may communicate MACB data transmission 400, for example, according to MACB scheme 200 (Fig. 2). [00142] In some demonstrative embodiments, as shown in Fig. 4, for example, the master AP may transmit a 20 MHz MACB-RTS frame 420 (Fig. 2) to the STA.

[00143] In some demonstrative embodiments, as shown in Fig. 4, for example, a SIFS time 421 or any other time, after the reception of the MACB-RTS frame 420, the STA, e.g. the receiver of the MACB-RTS frame 420, may transmit a 20 MHz MACB- TRIGGER frame 422 to the master AP0, for example, if the STA senses the primary channel 410 and the secondary 40 MHz channels 414 are idle. [00144] In some demonstrative embodiments, as shown in Fig. 4, secondary channel 412 may be busy, and, accordingly, trigger frame 422 may be transmitted only to the master AP.

[00145] In some demonstrative embodiments, for example, a SIFS time 423 or any other time, after the reception of the MACB -TRIGGER frame 422, the master APOmay transmit a data packet 424 to the STA over the primary 20 MHz channel 410.

[00146] In some demonstrative embodiments, for example, a SIFS time 425 or any other time, after the reception of the data packet 424 from the master AP, the STA, e.g. the receiver of the data packet 424, may feedback a BA frame 426.

[00147] In some demonstrative embodiments, as shown in Fig. 4., data frame 424 may be transmitted only from the master AP, e.g., if secondary channel 412 is busy prior to transmission of the MACB -TRIGGER frame 422.

[00148] In some demonstrative embodiments, for example, as shown in Fig. 4, the MACB data transmissions from four APs, e.g., from APs0-3, to the cell edge (CE) STA over four adjacent 20 MHz channels of the 80MHZ channel 408 may not be initiated, for example, if the secondary 20 MHz channel 412, is sensed busy for PIFS duration immediately before the transmission of MACB-RTS frame 420, for example, even if the secondary channel 412 may soon become available. This situation may limit the performance of the CE STA, for example, at least since the multiple APs, e.g., APs0-3, may have less chance to transmit 20MHz data packets simultaneously.

[00149] Reference is made to Fig. 5, which schematically illustrates an MACB data transmission 500 to illustrate one or more technical aspects, which may be addressed in accordance with some demonstrative embodiments. [00150] In one example, MACB data transmission 500 may be over an 80MHz channel 508 BW including a first, a second, a third, and a fourth 20 MHz channels.

[00151] In some demonstrative embodiments, as shown in Fig. 5, the 80 MHz channel 508 may include a primary 20MHZ channel 510 including the first 20 MHz channel, and two secondary channels, a first 20MHZ secondary channel 512 including the second 20 MHz channel, and a second 40MHZ secondary channel 514, e.g., including the third and fourth 20MHZ channels. [00152] In some demonstrative embodiments, MACB data transmission 500 may implement a definition of a master AP, e.g., APO, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STAO.

[00153] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., APO; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3. [00154] In one example, MACB data transmission 500 may be over an 80MHz channel 508 BW including first, second, third, and fourth 20 MHz channels.

[00155] In one example, CE STA 240 (Fig. 2) and APs 202, 260, 262 and/or 264 (Fig. 2) may communicate MACB data transmission 500, for example, according to MACB scheme 200 (Fig. 2). [00156] In some demonstrative embodiments, as shown in Fig. 5, for example, the master AP 240 may transmit a 20 MHz MACB-RTS frame 520 to the STA.

[00157] In some demonstrative embodiments, as shown in Fig. 5, for example, a SIFS time 521 or any other time, after the reception of the MACB-RTS frame 520, the STA e.g. the receiver of the MACB-RTS frame 520, may transmit a 20 MHz MACB- TRIGGER frame 522.

[00158] In some demonstrative embodiments, as shown in Fig. 5, both secondary channels 512 and 514 may be busy, and accordingly, trigger frame 522 may be transmitted only to the master AP.

[00159] In some demonstrative embodiments, for example, a SIFS time 523 or any other time, after the reception of the MACB -TRIGGER frame 522, the master APO may transmit a data packet 524 to the STAOover the primary 20 MHz channel 510.

[00160] In some demonstrative embodiments, as shown in Fig. 5, data frame 524 may be transmitted only from the mater APO, e.g., if both secondary channels 512 and 514 are busy, prior to transmission of the MACB-TRIGGER frame 522. [00161] In some demonstrative embodiments, for example, a SIFS time 525 or any other time, after the reception of the data packet 524 from the master AP0, the STA, e.g., the receiver of the data packet 524, may feedback a BA frame 526.

[00162] In some demonstrative embodiments, for example, as shown in Fig. 5, the MACB data transmissions from four APs, e.g., APs0-3, to the cell edge (CE) STA, e.g., the STA, over four adjacent 20 MHz channels of the 80MHZ channel may not be initiated, for example, if the secondary 20 MHz channel 512, and/or the 40 MHz channel 514 is sensed busy for PIFS duration immediately before the transmission of MACB-RTS frame 520, for example, even if the secondary channels 512 and/or 514 may soon become available. This situation may limit the performance of the CE STA, for example, at least since the multiple APs, e.g., APs 0-3, may have less chance to transmit 20MHz data packets simultaneously.

[00163] Reference is made to Fig. 6, which schematically illustrates an MACB data transmission 600 to illustrate one or more technical aspects, which may be addressed in accordance with some demonstrative embodiments.

[00164] In some demonstrative embodiments, for example, as shown in Fig. 6, MACB data transmission 600 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3", and a STA, denoted STA0, e.g., a CE STA, which may be associated with the multiple APs.

[00165] In some demonstrative embodiments, MACB data transmission 600 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STA0.

[00166] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary APs, e.g., of APs 1-3. [00167] In one example, MACB data transmission 600 may be over an 80MHz channel 608 BW including a first, a second, a third, and a fourth 20 MHz channels. [00168] In some demonstrative embodiments, as shown in Fig. 6, the 80 MHz channel 608 may include a primary 20MHZ channel 610 including the first 20 MHz channel, and two secondary channels, a first 20MHZ secondary channel 612 including the second 20 MHz channel, and a second 40MHZ secondary channel 614, e.g., including the third and fourth 20MHZ channels.

[00169] In one example, CE STA 240 (Fig. 2) and APs 202, 260, 262 and/or 264 (Fig. 2) may communicate MACB data transmission 600, for example, according to MACB scheme 200 (Fig. 2).

[00170] In some demonstrative embodiments, as shown in Fig. 6, for example, the master AP may transmit two duplicated 20 MHz MACB-RTS frames 620 to the STA, for example, if the master AP senses the secondary channel 614 is busy.

[00171] In some demonstrative embodiments, as shown in Fig. 6, for example, a SIFS time 621 or any other time, after the reception of the MACB-RTS frame 620, the STA, e.g., the receiver of the MACB-RTS frame 620, may transmit two duplicated 20 MHz MACB -TRIGGER frames 622 to two of the coordinated APs, e.g., to the master AP and API, for example, if the STA0 senses the primary channel 610 and the secondary channel 612 are idle.

[00172] In some demonstrative embodiments, for example, a SIFS time 623 or any other time, after the reception of the MACB -TRIGGER frame 622, the master AP and API may transmit data packets 624 to the STA over the primary channel 610 and secondary 20 MHz channel 612, respectively.

[00173] In some demonstrative embodiments, for example, a SIFS time 625 or any other time, after the reception of the data packets 624 from the master AP and API, the STA, e.g., the receiver of the data packet 624, may feedback a BA frame 626. [00174] In some demonstrative embodiments, for example, as shown in Fig. 6, the MACB data transmissions from four APs, e.g., APs 0-3, to the cell edge (CE) STA, over four adjacent 20 MHz channels of the 80MHZ channel may not be initiated, for example, if the secondary 40MHz channel 614 is sensed busy for PIFS duration immediately before the transmission of MACB-RTS frame 620, for example, even if the secondary channel 614 may soon become available. This situation may limit the performance of the CE STA, for example, at least since the multiple APs, e.g., APs 0- 3, may have less chance to transmit 20MHz data packets simultaneously. [00175] In some demonstrative embodiments, for example, as shown in Figures 4-6, an MACB data transmissions from multiple APs, e.g., from APs 0-3, to the CE STA over four adjacent 20 MHz channels may not be initiated, for example, in one or more cases, for example, if a secondary 20 MHz channel and/or a 40 MHz channel are sensed busy for PIFS duration immediately before an MACB-RTS frame transmission, for example, even if the secondary channels may soon become available. This situation may limit the performance of the CE STA, for example, at least since the multiple APs may have less chance to transmit 20MHz data packets simultaneously. [00176] In some demonstrative embodiments, an MACB scheme may be configured to utilize an enhanced multiple-AP channel bonding transmission, which may be configured to minimize a waste of spectrum resources, for example, by enabling asynchronous or delayed downlink transmissions from coordinated APs, for example, using self-interference cancellation (SIC) techniques, which may be available in antenna, analog circuitries and digital baseband, and multiple receiver chains in the STA, e.g., as described below.

[00177] In some demonstrative embodiments, for example, the MACB scheme may be configured to enable one or more APs, e.g., SIC-capable APs, to decode the MACB-TRIGGER frame from the CE STA over their secondary channels, for example, while transmitting data on their primary 20 MHz channel, e.g., as described below.

[00178] In some demonstrative embodiments, the primary channel of the coordinated APs may be different from the primary channel of the CE STA.

[00179] In some demonstrative embodiments, for example, once the APs finish their current data transmission to their associated STAs, the APs may be allowed to start a DL data transmission to the CE STA, for example, to achieve higher throughput performance, e.g., as described below.

[00180] In some demonstrative embodiments, the CE STA may be configured to process multiple streams from multiple APs asynchronously, e.g., in parallel with multiple receiver chains.

[00181] In some demonstrative embodiments, a coordinated AP may be configured to suppress its own transmitted signal (self-interference), for example, sufficient enough to perform signal detection on adjacent channels, thereby allowing the AP to decode the information indicated in the MACB -TRIGGER frame sent by the CE STA, for example, even while transmitting data over the secondary 20 or 40 MHz channels.

[00182] In some demonstrative embodiments, the CE STA may be equipped with multiple receiver chains and/or may be capable of processing multiple data packets sent from multiple APs, e.g., asynchronously in parallel.

[00183] In some demonstrative embodiments, the coordinated AP(s) may be allowed to opportunistically initiate an additional MACB data transmission to a CE STA over the secondary 20 or 40 MHz channels of the CE STA, for example, even during an on-going data transmission from the master AP to the CE STA over the primary 20 MHz channel, for example, to allow improved DL throughput performance of the CE STA, e.g., as described below.

[00184] In some demonstrative embodiments, a coordinated AP (may be able to decode an MACB-TRIGGER frame from a CE STA over secondary channels of the coordinated AP, e.g., primary 20MHz or secondary 40MHz of a master AP, for example, using the SIC capability or any other additional or alternative technique, for example, while transmitting data over a primary channel of the coordinated AP, e.g., secondary 20MHz channel of the master AP, to its associated STA. For example, once the coordinated AP finishes the current data transmission to its associated STA, the coordinated AP can start a DL data transmission to the CE STA.

[00185] In some demonstrative embodiments, the CE STA may be capable of processing multiple data packets, e.g., sent from multiple APs over different 20 MHz channels asynchronously in parallel, for example, with multiple receiver chains.

[00186] In some demonstrative embodiments, an enhanced wideband transmission technique may not be suitable for some implementations. For example, an enhanced wideband transmission technique may utilize a SIC capability of an AP to sense secondary channels and/or to initiate wideband data transmission in the middle of an on-going narrowband data transmission, so as to increase the DL physical data rate to a STA. However, this approach may work only when the STA is able to communicate with the AP over a wide bandwidth, e.g., a BW of 80 MHz.

[00187] In contrast to the enhanced wideband transmission, the MACB schemes described herein may be implemented, for example, to enable enhanced wideband transmission even to CE STAs, and/or other STAs, which are able to only communicate with the AP over narrow bandwidth, e.g., a BW of 20MHz, for example, by initiating MACB data transmission even during an on-going narrowband data transmission. [00188] In one example, the MACB may provide an increased, e.g., up to four times, physical data rate gain with coordination of four APs, for example, when comparing to the case where the CE STA can only receive a 20 MHz data packet from a single AP.

[00189] In some demonstrative embodiments, it may not be advantageous to utilize a technique to allow a master AP to initiate an MACB data transmission from multiple APs to a CE STA over multiple adjacent 20 MHz channels in a middle of a data transmission from a single AP to the STA over a narrower 20 MHz bandwidth, e.g., so as to improve the DL throughput performance of the CE STA. For example, this can be done by the master AP continuously sensing the secondary channels using the SIC capability. However, this approach may work only when the CE STA is receiving data from a single AP, e.g., as shown in Figs. 4 and 5. In addition, this approach may not efficiently support initiating the MACB data transmission from multiple APs to the CE STA, e.g., if one or more secondary APs are busy or the Network Allocation Vector (NAV) setting is not expired. [00190] In some demonstrative embodiments, for example, there may be overlapping Basic Service Sets (BSSs), and the secondary 20 or 40 MHz channels may be occupied by other STAs.

[00191] In some demonstrative embodiments, when a master AP and/or one or secondary APs have data to transmit to a STA, the master AP, secondary APs and/or the STA may be allowed to initiate the transmission, for example, based on one or more criteria and/or conditions, e.g., as described below.

[00192] Referring back to Fig. 1, in some demonstrative embodiments, device 102 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of the master AP; device 140 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of the CE STA, device 160 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of a secondary AP, and/or device 180 may perform the functionality of, the role of, one or more operations of and/or one or more other STAs, e.g., as described below.

[00193] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to sense an idle/busy state of a plurality of channels, e.g., as described below.

[00194] In some demonstrative embodiments, the plurality of channels may include a primary channel and a plurality of secondary channels, e.g., as described below.

[00195] In some demonstrative embodiments, the primary channel may include a primary 20 Megahertz (MHz) channel. In other embodiments, the primary channel may include any other channel.

[00208] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to receive, e.g., from device 102, the one or more duplicates of the MACB-RTS frame, for example, over the one or more idle channels, e.g., as described below.

[00248] In some demonstrative embodiments, device 140 may receive the first DL transmission, e.g., the master transmission, from device 102 over a first channel in a first frequency band, and the one or more second DL transmissions, the secondary DL transmissions, from device 160, over one or more second channels in the first frequency band, e.g., as described below.

[00249] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to receive the MACB-RTS, e.g., from device 102, and to transmit the MACB -trigger frame, e.g., to device 102, over a second frequency band different from the first frequency band, e.g., as described below.

[00250] In some demonstrative embodiments, the primary channel and the secondary channel of device 160 may be in a first frequency band, e.g., as described below.

[00251] In some demonstrative embodiments, controller 174 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 160 to receive the MACB -trigger frame, from device 140, in a second frequency band different from the first frequency band, e.g., as described below.

[00252] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to perform one or more operations of an MACB transmission scheme, for example, when a secondary 20 MHz channel is busy, e.g., as described below with reference to Fig. 7; when a secondary 20 MHz and a secondary 40 MHz channel are busy, e.g., as described below with reference to Fig. 8; and/or even when a secondary 40 MHz channel is busy e.g., as described below with reference to Fig. 9.

[00253] Reference is made to Fig. 7, which schematically illustrates of an MACB transmission 700, in accordance with some demonstrative embodiments.

[00254] In some demonstrative embodiments, for example, as shown in Fig. 7, MACB data transmission 700 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a plurality of STAs, e.g., including a first STA, denoted "STA0", e.g., a CE STA, which may be associated with the multiple APs, and a second STA, denoted "STA1".

[00255] In some demonstrative embodiments, MACB data transmission 700 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STA0. [00256] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3, and/or device 180 may be configured to operate as, perform a role of, and/or perform one or more functionalities of, STA1.

[00257] In one example, MACB data transmission 700 may be over an 80MHz channel BW 708 including first, second, third, and fourth 20 MHz channels. [00258] In some demonstrative embodiments, as shown in Fig. 7, the 80 MHz channel 708 may include a primary 20MHZ channel 710 including the first 20 MHz channel, and two secondary channels, e.g., including a first 20MHZ secondary channel 712 including the second 20 MHz channel, and a second 40MHZ secondary channel 714, e.g., including the third and fourth 20MHZ channels. [00259] In some demonstrative embodiments, the MACB transmission 700 may be performed, for example, even when the secondary 20 MHz channel 712 is busy, e.g., as described below.

[00260] In some demonstrative embodiments, the master AP0 may sense the secondary channels 712 and/or 714, for example, during an interval of a PIFS or any other time, immediately preceding its backoff expiration or the start of the TXOP and may decide on the TX channel bandwidth.

[00261] In some demonstrative embodiments, for example, if both the secondary 20 MHz channel 712 and the 40 MHz channel 714 are idle, the master AP0, secondary APs 1-3 and the STAO may follow the MACB procedure, e.g., as described above with reference to Fig. 3.

[00262] In some demonstrative embodiments, as shown in Fig. 7, the master AP, secondary AP and/or STA may perform MACB transmission 700, for example, if the secondary 40 MHz channel 714 is idle and the secondary 20 MHz channel 712 is busy, for example, occupied for data transmission 731 from first secondary API to its associated STA1, e.g., as describe below. [00263] In some demonstrative embodiments, as shown in Fig. 7, the master AP0 may transmit three duplicated 20 MHz MACB-RTS frames 720 over the primary 20 MHZ channel 710 and the secondary 40 MHz channel 714 to the STA0.

[00264] In some demonstrative embodiments, for example, a SIFS time 723 or any other time, after the reception of the MACB-TRIGGER frame 722 from the STA0, the master AP0 may transmit a 20 MHz PPDU packet 724 to the STA0 over the primary 20 MHz channel 710, for example, based on the information indicated in an MACB-TRIGGER frame 722 from the STA0.

[00265] In some demonstrative embodiments, as shown in Fig. 7, for example, after transmitting the 20 MHz packet 724, the master AP0 may wait for a BA frame 720 over the transmitted channel, e.g. the primary 20 MHz channel 710.

[00266] In some demonstrative embodiments, while transmitting the data packet 731 to the STAl, which is associated with API over the secondary 20 MHz channel 712, the first secondary AP (API) may keep monitoring the primary 20 MHz channel 712, for example, by utilizing self-interference cancellation (SIC) techniques and/or any other additional or alternative techniques.

[00267] In some demonstrative embodiments, for example, if the API detects the MACB-TRIGGER frame 722 from the STA0 and knows that the duration of transmission of the buffered frame to THE STA0 plus current packet exchange with STAl is less than the time indicated in MACB-TRIGGER frame 720 for data transmission from AP0 to STA0, then the API may initiate an MACB data transmission 734 to the STA0 over the secondary 20 MHz channel 712 after the current packet exchange 731 with STAl.

[00268] In some demonstrative embodiments, for example, as shown in Fig. 7, after transmitting the packet 731 to the STAl, the API may wait for a BA frame 732 from STAl over the transmitted channel 712.

[00269] In some demonstrative embodiments, for example, as shown in Fig. 7, after the reception of the BA frame 732 from the STAl, the API may prepare a DL data packet 734 for STA0, for example, based on the information indicated in the MACB- TRIGGER frame 722. The packet transmission 734 from API to the STA0 may be completed, for example, by the end of packet transmission 724 from the master AP0 to the STA0, e.g., over the primary channel 710. [00270] In some demonstrative embodiments, for example, as shown in Fig. 7, a SIFS time or any other time, after reception of the BA frame 732 from the STA1, the API may initiate the data packet transmission 734 to the STA0 over the secondary 20 MHz channel 712.

[00271] In some demonstrative embodiments, for example, to protect the packet transmission from API to the STA0 over the secondary 20 MHz channel 712 from 3rd party STAs, the API may reserve the medium, for example, with a longer time duration than a duration needed for the packet exchange with the STA1.

[00272] In some demonstrative embodiments, for example, if there is no packet transmission from API to the STA0 after the packet transmission to the STA 1, the API may send a Contention Free end (CF-End) frame for 3rd party STAs to reset their NAV.

[00273] In some demonstrative embodiments, for example, the API may send a Clear to Send to self (CTS-to-self frame), e.g., a SIFS time after the reception of the BA frame 732 from the STA1, for example, to reserve the medium for packet transmission 734 to the STA0.

[00274] In some demonstrative embodiments, for example, as shown in Fig. 7, after transmitting the 20 MHz data packet 734, the API may wait for a BA frame 727 over the transmitted channel 712.

[00275] In some demonstrative embodiments, the one or more other secondary APs, e.g., AP2 and/or AP3, may transmit data packets 735 to the STA0, e.g., as described below.

[00276] In some demonstrative embodiments, as shown in Fig. 7, for example, a SIFS time 723 or any other time, after the reception of MACB-TRIGGER frame 722 from the STA0, the other secondary APs, e.g., AP2 and AP3, which may be identified in the MACB-TRIGGER frame 722, may transmit data packets 735 to the STA0 over the third and fourth 20 MHz channels, respectively, e.g., the secondary 40MHZ channel 714.

[00277] In some demonstrative embodiments, for example, as shown in Fig. 7, after transmitting the 20 MHz packets 735 to the STA0, AP2 and AP3 may wait for a BA frame 728 over the transmitted channel 714. [00278] In some demonstrative embodiments, the STAO may follow one or more rules, e.g., in accordance with an IEEE 802.11 Specification, and may respond with one or more MACB -TRIGGER frames 722, for example, when it receives the one or more MACB-RTS frames 720 from the master AP0.

[00279] In some demonstrative embodiments, as shown in Fig. 7, for example, if the STAO does not detect any interference on primary 20 MHz channel 710 and secondary 40 MHz channel 714, for example, a PIFS prior to and SIFS 721 after, the reception of the MACB-RTS frames 720, the STAO may respond with three duplicated MACB -TRIGGER frames 722 over the primary 20 MHz channel 710 and secondary 40 MHz channel 714, for example, to trigger the master AP0, and the secondary APs, AP2 and AP3, to transmit DL data packets 735 to the STAO.

[00280] In some demonstrative embodiments, as shown in Fig. 7, the STAO may receive DL data packets 734 and 735, e.g., the three 20 MHz packets, for example, three 20 MHz A-MPDU packets, and decode A-MPDU subframes that are received correctly.

[00281] In some demonstrative embodiments, for example, while the STAO receiving the 20 MHz packets over the primary 20 MHz channel 710 and secondary 40 MHz channel 714, the STAO may keep monitoring the secondary 20 MHz channel 712, for example, using multiple receiver chains.

[00282] In some demonstrative embodiments, for example, once the STAO detects a new packet, e.g., data packet 734, over the secondary 20 MHz channel 712, the STAO may start a new packet reception over the secondary 20 MHz channel 712, for example, in parallel with the packet reception over the primary 20 MHz channel 710 and the secondary 40 MHz channel 714. The packet receptions over different channels may be done using the different receiver chains.

[00283] In some demonstrative embodiments, for example, a SIFS time 725 or any other time, after the reception of the date packets 724, 734, and/or 735 from all the coordinated APs, e.g., APs0-3, the STAO may respond back BA frames 726 over the channels it has received packet.

[00284] Reference is made to Fig. 8, which schematically illustrates of an MACB transmission 800, in accordance with some demonstrative embodiments.

[00285] In some demonstrative embodiments, for example, as shown in Fig. 8, MACB data transmission 800 may be performed between multiple APs, e.g., including a first AP denoted "APO", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a plurality of STAs, e.g., including a first STA, denoted "STAO", e.g., a CE STA, which may be associated with the multiple APs, a second STA, denoted "STA1", a third STA, denoted "STA2", and a fourth STA, denoted "STA3".

[00286] In some demonstrative embodiments, MACB data transmission 800 may implement a definition of a master AP, e.g., APO, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STAO.

[00287] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., APO; device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3, and/or device 180 may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a STA, e.g., of STAs 1-3.

[00288] In one example, MACB data transmission 800 may be over an 80MHz channel BW 808 including first, second, third, and fourth 20 MHz channels.

[00289] In some demonstrative embodiments, as shown in Fig. 8, the 80 MHz channel 808 may include a primary 20MHZ channel 810 including the first 20 MHz channel, and two secondary channels, e.g., including a first 20MHZ secondary channel 812 including the second 20 MHz channel, and a second 40MHZ secondary channel 814, e.g., including the third and fourth 20MHZ channels.

[00290] In some demonstrative embodiments, the master APO may sense the secondary channels 812 and/or 814, for example, during an interval of a PIFS or any other time, immediately preceding its backoff expiration or the start of the TXOP and may decide on the TX channel bandwidth.

[00291] In some demonstrative embodiments, for example, if both the secondary 20 MHz channel 812 and the 40 MHz channel 814 are idle, the master APO, secondary APsl-3 and the STAO may follow the MACB procedure 300 (Fig. 3). [00292] In some demonstrative embodiments, the MACB transmission 800 may be performed, for example, when the secondary 20 MHz channel 812 and the secondary 40 MHz channel 814 are busy, e.g., as described below.

[00293] In some demonstrative embodiments, as shown in Fig. 8, the master AP, secondary APs 1-3 and/or STAs 0-3 may perform MACB transmission 800, for example, if the secondary 20 MHz channel 812 and the secondary 40 MHz channel 814 are busy, for example, occupied for data transmissions from APs 1-3 to their associated STAs, STAs 1-3, e.g., as described below.

[00294] In some demonstrative embodiments, for example, as shown in Fig. 8, the master AP (APO) may transmit a 20 MHz MACB-RTS frame 820 to STAO.

[00295] In some demonstrative embodiments, for example, as shown in Fig. 8, a SIFS time 823 or any other time, after the reception of an MACB-TRIGGER frame 822 from the STAO, the master APO may transmit a 20 MHz PPDU packet 824 to the STAO, for example, in accordance with an A-MPDU format of an IEEE 802.1 lac Specification or any other Specification.

[00296] In some demonstrative embodiments, for example, as shown in Fig. 8, after transmitting the 20 MHz packet 824, the master APO may wait for a BA frame 826 over the transmitted channel 810.

[00297] In some demonstrative embodiments, as shown in Fig. 8, one or more of the secondary APs, e.g., all secondary APs, (API, AP2 and AP3) may transmit data packets 831, 832 and 833, to STAsl-3 over three 20 MHz secondary channels of the 80 MHZ channel 808, respectively.

[00298] In some demonstrative embodiments, for example, while transmitting the data packets 831, 832 and 833 to STAsl-3, the APsl-3 may keep monitoring the primary 20 MHz channel 810, for example, by utilizing SIC and/or any other technique.

[00299] In some demonstrative embodiments, for example, as shown in Fig. 8, if the secondary APs detect the MACB-TRIGGER frame 822 from the STAO and the duration of transmission of the buffered frames to STAO plus current packet exchange with the STAsl-3 is less than the time indicated in MACB-TRIGGER frame 822 for data transmission from the master APO to the STAO, then the secondary APs may initiate the MACB data transmission to the STAO over the secondary 20 MHz channels of the 80 MHZ channel 808, for example, after current packet exchange 831, 832, and 833 with STAs 1-3, respectively.

[00300] In some demonstrative embodiments, for example, as shown in Fig. 8, after transmitting the packets 831, 832, and/or 833 to STAs 1-3, the APs 1-3 may wait for BA frames 835 over the respective transmitted channel.

[00301] In some demonstrative embodiments, for example, as shown in Fig. 8, after the reception of the BA frames 835 from STAs 1-3, APs 1-3 may prepare the DL data packets 836 for the STAO, for example, based on the information indicated in the MACB-TRIGGER frame 822. The packet transmissions 836 from APs 1-3 to the STAO may be completed, for example, by the end of packet transmission 824 from the master AP0 to the STAO over the primary channel 810.

[00302] In some demonstrative embodiments, for example, as shown in Fig. 8, a SIFS time or any other time, after reception of the BA frame from STAs 1-3, APs 1-3 may initiate data packet transmission 836 to the STAO over the secondary, third and/or fourth 20 MHz channels of the 80 MHZ channel 808.

[00303] In some demonstrative embodiments, the APs 1-3 may reserve the medium with a longer time duration than a duration needed for the packet exchanges 831, 832, and/or 833 with STAs 1-3, for example, in order to protect from 3rd party STAs the packet transmissions 836 from APs 1-3 to the STAO over the secondary 20 and/or secondary 40 MHz channels of the 80 MHZ channel 808. For example, if there is no packet transmission from APs 1-3 to the STAO after the packet transmission to STAs 1-3, the APs 1-3 may send a CF-End frame for 3rd party STAs to reset their NAV. For example, the APs 1-3 may send a CTS-to-self frame SIFS time after the reception of the BA frames 835 from STAs 1-3 to reserve the medium for packet transmissions 836 to STA 0.

[00304] In some demonstrative embodiments, for example, as shown in Fig. 8, after transmitting the 20 MHz packets 836, APs 1-3 may wait for BA frames 826 over the transmitted channel.

[00305] In some demonstrative embodiments, for example, as shown in Fig. 8, the STAO may follow one or more rules, e.g., in accordance with an IEEE 802.11 Specification, and may respond with one or more MACB-TRIGGER frames 822, for example, when it receives one or more MACB-RTS frames 820 from the master AP0. [00306] In some demonstrative embodiments, for example, as shown in Fig. 8, the STAO may respond with one MACB -TRIGGER frame 822 over the primary 20 MHz channel 810, for example, to trigger the master AP0 to transmit DL data packet 824 to the STAO.

[00307] In some demonstrative embodiments, for example, as shown in Fig. 8, the STAO may receive the 20 MHz packet 824, e.g., 20 MHz A-MPDU packet, and may decode A-MPDU subframes that are received correctly.

[00308] In some demonstrative embodiments, for example, while receiving the 20 MHz packet 824 over the primary 20 MHz channel 810, the STAO may keep monitoring the secondary 20 MHz channel 812 and/or the secondary 40 MHz channel 814, for example, using multiple receiver chains. For example, once the STAO detects a new packet over the secondary 20 MHz channel 812 and/or the secondary 40 MHz channel 814, the STAO may start a new packet reception over the secondary channels of the 80 MHZ channel 808 in parallel with the packet reception of the data packet 824 over the primary 20 MHz channel 810. The packet receptions over different channels may be performed, for example, over different receiver chains.

[00309] In some demonstrative embodiments, for example, as shown in Fig. 8, a SIFS time or any other time, after the reception of the packet 824 from all the coordinated APs, the STAO may respond back with BA frames 826 to the APs0-3 over the channels it has received a packet.

[00310] Reference is made to Fig. 9, which schematically illustrates of an MACB transmission 900, in accordance with some demonstrative embodiments.

[00311] In some demonstrative embodiments, for example, as shown in Fig. 9, MACB data transmission 900 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a plurality of STAs, e.g., including a first STA, denoted "STAO", e.g., a CE STA, which may be associated with the multiple APs, a second STA, denoted "STA2", and a third STA, denoted "STA3".

[00312] In some demonstrative embodiments, MACB data transmission 900 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STAO.

[00313] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the STAO; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., APO; device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3, and/or device 180 may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a STA, e.g., of STAs 2-3.

[00314] In one example, MACB data transmission 900 may be over an 80MHz channel BW 908 including first, second, third, and fourth 20 MHz channels.

[00315] In some demonstrative embodiments, as shown in Fig. 9, the 80 MHz channel 908 may include a primary 20MHZ channel 910 including the first 20 MHz channel, and two secondary channels, e.g., including a first 20MHZ secondary channel 912 including the second 20 MHz channel, and a second 40MHZ secondary channel 914, e.g., including the third and fourth 20MHZ channels.

[00316] In some demonstrative embodiments, the master APO may sense the secondary channels 912 and/or 914, for example, during an interval of a PIFS or any other time, immediately preceding its backoff expiration or the start of the TXOP and may decide on the TX channel bandwidth.

[00317] In some demonstrative embodiments, for example, if both the secondary 20 MHz channel 912 and the 40 MHz channel 914 are idle, the master APO, secondary APs 1-3 and the STAO may follow the MACB procedure 300 (Fig. 3).

[00318] In some demonstrative embodiments, the MACB transmission 900 may be performed, for example, when the secondary 40 MHz channel 914 is busy, e.g., as described below.

[00319] In some demonstrative embodiments, as shown in Fig. 9, the master AP, the secondary APs and/or the STAs may perform MACB transmission 900, for example, if the secondary 40 MHz channel 914 is busy, for example, occupied for data transmission from APs2-3 to their associated STAs, e.g., STAs2-3, respectively, e.g., as described below.

[00320] In some demonstrative embodiments, as shown in Fig. 9, the master APOmay transmit two duplicated 20 MHz MACB-RTS frames 920 to the STAO over the primary channel 910 and the secondary 20 MHz channel 912. [00321] In some demonstrative embodiments, for example, as shown in Fig. 9, a SIFS time 923 or any other time, after the reception of the MACB -TRIGGER frame 920, the master APO may transmit to the STA0 a 20 MHz PPDU packet 924, for example, in accordance with an A-MPDU format, e.g., in compliance with an IEEE 802.11ac Specification, for example, based on the information indicated in the MACB-TRIGGER frame 922.

[00322] In some demonstrative embodiments, for example, as shown in Fig. 9, after transmitting the 20 MHz packet 924, the master APO may wait for a BA frame 926 from the STA0 over the transmitted channel 910.

[00323] In some demonstrative embodiments, for example, as shown in Fig. 9, a SIFS time 923 or any other time, after the reception of MACB-TRIGGER frame 922 from the STA0, a first secondary AP (AP 1), which may be identified in the MACB- TRIGGER frame 920, may transmit a data packet 934 to the STA0 over the secondary 20 MHz channel 912.

[00324] In some demonstrative embodiments, for example, as shown in Fig. 9, after transmitting the 20 MHz packet 934 to the STA0, the API may wait for a BA frame 926 over the transmitted channel 912.

[00325] In some demonstrative embodiments, as shown in Fig. 9, one or more of the secondary APs, e.g., AP2 and/or AP3, may transmit data packets 931 and 932 to STA2 and/or STA3 over the third and/or fourth channel 20 MHz channels of the 80 MHZ channel 908, respectively.

[00326] In some demonstrative embodiments, for example, as shown in Fig. 9, while transmitting the data packets 931 and 932 to STA2 and/or STA3, respectively, AP2 and/or AP3 may keep monitoring the primary 20 MHz channel 910, for example, by utilizing SIC and/or any other technique.

[00327] In some demonstrative embodiments, for example, as shown in Fig. 9, if the AP2 and/or AP3 detect the MACB-TRIGGER frame 922 from the STA0 and the duration of transmission of the buffered frame to the STA0 plus current respective packet exchange with STA2 and/or STA3 is less than the time indicated in the MACB-TRIGGER frame 922 for data transmission from the master APO to the STA0, then AP2 and/or AP3 may initiate the MACB data transmission to the STA0 over the third and/or fourth 20 MHz channels of the 80 MHZ channel 908, for example, after current packet exchange 931 and 932 with STA2 and/or STA3, respectively. [00328] In some demonstrative embodiments, for example, as shown in Fig. 9, after transmitting the packets 931 and 932 to STA 2 and STA 3, respectively, the AP2 and AP3 may wait for BA frames 933 over the transmitted channel 914.

[00329] In some demonstrative embodiments, for example, as shown in Fig. 9, after the reception of the BA frames 933 from STA2 and/or STA3, the AP2 and/or AP3 may prepare the data packets 935 for the STAO, for example, based on the information indicated in the MACB-TRIGGER frame 922 from the STAO. The packet transmission 935 from AP2 and/or AP3 to the STA 0 may be completed by the end of packet transmission 924 from the master APO to the STAO over the primary channel 910.

[00330] In some demonstrative embodiments, for example, as shown in Fig. 9, a SIFS time or any other time, after reception of the BA frame 933 from STA 2 and/or STA 3, the AP2 and/or AP3 may initiate data packet transmission 935 to the STAO over the third and/or fourth 20 MHz channels of the 80 MHZ channel 908.

[00331] In some demonstrative embodiments, for example, to protect from 3rd party STAs the packet transmission from the API and/or AP2 to the STAO over the third and/or fourth 20 MHz channels of the 80 MHZ channel 908, the API and/or AP2 may reserve the medium with a longer time duration than a duration needed for the packet exchanges 931 and 932 with STA 1 and/or STA 2. For example, if there is no packet transmission from API and/or AP2 to the STAO after the packet transmission to STA1 and/or ST 2, the API and/or AP2 may send a CF-End frame for 3rd party STAs to reset their NAV. For example, the API and/or AP2 may send a CTS-to-self frame SIFS time after the reception of the BA frames 933 from STA1 and/or STA 2 to reserve the medium for packet transmission 935 to the STAO.

[00332] In some demonstrative embodiments, for example, as shown in Fig. 9, after transmitting the 20 MHz packets 935, the AP2 and/or AP3 may wait for BA frames 926 over the transmitted channel.

[00333] In some demonstrative embodiments, for example, as shown in Fig. 9, the STAO may follow one or more rules, e.g., in accordance with an IEEE 802.11 Specification, and may respond with one or more MACB-TRIGGER frames 922, for example, when it receives one or more MACB-RTS frames 920 from the master APO.

[00334] In some demonstrative embodiments, for example, as shown in Fig. 9, if the STAO does not detect any interference over the primary and secondary 20 MHz channels of the 80 MHZ channel 908, the STAO may respond with two duplicated MACB -TRIGGER frames 922 over the primary and secondary 20 MHz channels of the 80 MHZ channel 908, for example, to trigger the master AP0 and API to transmit DL data packets 924 and 934, respectively, to the STA 0.

[00335] In some demonstrative embodiments, for example, as shown in Fig. 9, the STAO may receive the two 20 MHz packets 924 and/or 934, e.g., two 20 MHz A- MPDU packets, and may decode A-MPDU subframes that are received correctly.

[00336] In some demonstrative embodiments, for example, while receiving the two 20 MHz packets 924 and 934 over the primary channel 910 and the secondary 20 MHz channel 912 of the 80 MHZ channel 908, the STAO may keep monitoring the secondary 40 MHz channel 914, for example, using multiple receiver chains. For example, once the STAO detects a new packet over the secondary 40 MHz channel 914, the STAO may start a new packet reception over the secondary channels 914, e.g., in parallel with the packet reception over the primary channel 910 and the secondary 20 MHz channel 912. The packet receptions over different channels may be performed, for example, over different receiver chains.

[00337] In some demonstrative embodiments, for example, as shown in Fig. 9, a SIFS time or any other time, after the reception of the packets 924, 934, and/or 935 from all the coordinated APs, the STAO may respond back with BA frames 926 over the channels it has received a packet.

[00338] Referring back to Fig. 1, in some demonstrative embodiments, an MACB scheme, e.g., MACB scheme 300 (Fig. 3) may be configured to address one or more technical aspects, for example, to support efficient transmission, for example, even in cases that an AP and/or the CE STA cannot reach one another, e.g., as described below.

[00339] In one example, an MACB data transmission from an AP to a cell edge STA may not be initiated successfully, for example due to a large propagation loss and/or asymmetric transmit powers of the AP and the STA, e.g., as described below.

[00340] Reference is made to Fig. 10, which schematically illustrates an MACB communication scheme 1000 between an AP 1002 and a CE STA 1040 to illustrate one or more technical aspects, which may be addressed in accordance with some demonstrative embodiments. [00341] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA 1040; and/or device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, one of the AP 1002. [00342] In some demonstrative embodiments, as shown in Fig. 10, STA 1040 and AP 1002 may reach each other with 20MHz signals.

[00343] In some demonstrative embodiments, as shown in Fig. 10, AP 1002 may only reach CE STA 1040 with a 20MHz signal 1007.

[00344] In some demonstrative embodiments, as shown in Fig. 10, STA 1040 may only reach AP 1002 with a 20MHz signal 1047.

[00345] In some demonstrative embodiments, as shown in Fig. 10, STA 1040 may not be able to reach AP 1002 using a 80MHz signal 1049.

[00346] In some demonstrative embodiments, as shown in Fig. 10, transmission range of 20MHz signals 1047 and 1007, e.g., over the 5GHz band, is greater than 80MHz signal 1049, e.g., when using the same transmit power for STA 1040 and AP 1002.

[00347] Reference is made to Fig. 11, which schematically illustrates an MACB communication scheme 1100 between an AP 1102 and a CE STA 1140 to illustrate one or more technical aspects, which may be addressed in accordance with some demonstrative embodiments.

[00348] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA 1140; and/or device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, one of the AP 1002. [00349] In some demonstrative embodiments, as shown in Fig. 11, AP 1102 may reach CE STA 1140 with a 20MHz signal 1107 and/or a 80MHz signal 1109.

[00350] In some demonstrative embodiments, as shown in Fig. 11, STA 1140 may reach AP 1102 with a 20MHz signal 1147.

[00351] In some demonstrative embodiments, as shown in Fig. 11, STA 1140 may not be able to reach AP 1102 using a 80MHz signal 1149. [00352] In some demonstrative embodiments, as shown in Fig. 11, transmission range of 80MHz signal 1109, e.g., over the 5GHz band, is greater than transmission range of 80MHz signal 1149, e.g., over the 5GHz band, for example, since the transmit power of STA 1140 may usually be much lower than the transmit power of the AP 1102.

[00353] Referring back to Fig. 1, in some demonstrative embodiments, for example, as shown in Fig. 10 and/or Fig. 11, a STA and an AP may not be able to exchange four duplicated 20MHz MACB-RTS or MACB -TRIGGER frames from a beginning of the frame exchange sequence, for example, to enable an MACB data transmission, e.g., MACB data transmission 300.

[00354] In some demonstrative embodiments, an MACB scheme may implement an MACB MAC protocol, which may utilize a first band, e.g., the 2.4 GHz band, for control frames such as MACB-RTS, MACB -TRIGGER and BA frames; and/or utilize a second band, e.g., the 5GHz band, for downlink MACB data transmissions, e.g., as described below.

[00355] In some demonstrative embodiments, the MACB MAC protocol may utilize the 2.4 GHz band for the control frames, e.g. the MACB-RTS, the MACB -TRIGGER and/or the BA frames, for example, to enable a link between the AP and the CE STA having a better link budget, e.g., having a reduced propagation loss e.g., as described below.

[00356] In some demonstrative embodiments, the MACB MAC protocol may utilize the 5 GHz band for downlink MACB data transmissions, which may provide a wider bandwidth, e.g., 80 or 160MHz channel BW, compared to the 2.4GHz band, e.g., as described below. [00357] In some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to support concurrent Multi-Band Operation (MBO), e.g., operating at both the 2.4GHz and 5GHz bands at the same time.

[00358] In some demonstrative embodiments, the concurrent multi-band operation, may enable a cell edge STA to exchange the control frames, such as MACB-RTS, MACB-TRIGGER and BA frames, with coordinated APs, for example, using the 2.4GHz band; and/or to initiate the downlink MACB data transmission from multiple APs at the same time successfully using the 5GHz band, which may provide up to four times throughput gain for the CE STA, e.g., as described below.

[00359] In some demonstrative embodiments, devices 102, 140 160 and/or 180 may configured to perform MACB data transmission using concurrent multi-band operation, e.g., as described below.

[00360] In some demonstrative embodiments, device 102 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of the master AP; device 140 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of the CE STA, device 160 may perform the functionality of, the role of, one or more operations of and/or one or more functionalities of a secondary AP, and/or device 180 may perform the functionality of, the role of, one or more operations of and/or one or more other STAs e.g., as described below.

[00361] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to sense an idle/busy state of a plurality of channels in a first frequency band, for example, the 5GHz band, e.g., as described below.

[00362] In some demonstrative embodiments, the plurality of channels may include a primary channel and a plurality of secondary channels, e.g., as described below. [00363] In some demonstrative embodiments, the plurality of secondary channels may include at least a secondary 20MHz channel and a secondary 40MHz channel. In other embodiments, the plurality of secondary channels may include any other channels.

[00364] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to transmit to a wireless station (STA), e.g., STA 140, an MACB-RTS frame over a second frequency band, e.g., the 2.4GHz band, to request to reserve a wireless medium for an MACB DL transmission to the STA, for example, when at least the primary channel is idle, e.g., as described below.

[00365] In some demonstrative embodiments, the first frequency band may include the 5 GHz band, and the second frequency band may include the 2.4GHz band. In other embodiments, any other frequency bands may be used. [00366] In some demonstrative embodiments, the MACB-RTS frame may include an indication of the one or more secondary channels for the MACB DL transmission, e.g., as described above.

[00367] In some demonstrative embodiments, the MACB DL transmission may include a first DL transmission (also referred to as a "master DL transmission") from device 102 to device 140 over the primary channel and one or more second DL transmissions (also referred to as "secondary DL transmissions") from one or more secondary APs, e.g., including device 160, to device 140 over one or more secondary channels of the plurality of secondary channels, e.g., as described below.

[00368] In some demonstrative embodiments, controller 124 may be configured to allow the wireless communication station implemented by device 102 to transmit the MACB-RTS frame, for example, when at least one of the one or more secondary channels is busy, e.g., as described above.

[00369] In some demonstrative embodiments, controller 124 may be configured to allow the wireless communication station implemented by device 102 to transmit the MACB-RTS frame, for example, when at least one of the one or more secondary channels is busy during a PIFS before transmission of the MACB-RTS frame, e.g., as described above.

[00370] In some demonstrative embodiments, controller 124 may be configured to allow the wireless communication station implemented by device 102 to transmit the MACB-RTS frame during communication of at least one of the one or more second APs, e.g., device 160, over at least one of the one or more secondary channels, e.g., as described above.

[00371] In some demonstrative embodiments, controller 124 may be configured to allow the wireless communication station implemented by device 102 to duplicate transmission of the MACB-RTS frame over at least one idle channel in the first frequency band, for example, the 5GHz band, e.g., as described below.

[00372] In some demonstrative embodiments, the at least one idle channel may include at least the primary channel, e.g., as described below.

[00373] In some demonstrative embodiments, device 140 may receive the MACB- RTS frame from device 102, for example, over the 2.4GHz band, e.g., as described below. [00374] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to receive from device 102 the MACB-RTS frame to request to reserve the wireless medium for the MACB Downlink DL transmission to device 140 during the MACB period, e.g., as described below.

[00375] In some demonstrative embodiments, the MACB-RTS frame may be received by device 140, for example, over the second frequency band different from the first frequency band, for example, over the 2.4GHz band e.g., as described below.

[00376] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to transmit an MACB-trigger frame over the second frequency band, e.g., the 2.4 GHz band, to trigger the MACB DL transmission, e.g., as described below.

[00377] In some demonstrative embodiments, the MACB-trigger frame may include one or more STA-indicated channels, which are indicated by device 140, for the MACB DL transmission, e.g., as described above.

[00378] In some demonstrative embodiments, the one or more STA-indicated channels may include the at least one busy channel, which is detected by device 140 to be busy prior to transmission of the MACB-trigger frame, e.g., as described above.

[00379] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to include in the MACB-trigger frame configuration information to configure the first MACB DL transmission, e.g., as described below.

[00380] In some demonstrative embodiments, the configuration information in the MACB-trigger frame may include resource allocation information and/or MCS information, e.g., as described above.

[00381] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to duplicate transmission of the MACB-trigger frame over one or more idle channels of the first and second channels in the first frequency band, for example, in the 5GHZ band, e.g., as described below. [00382] In some demonstrative embodiments, device 102 may receive the MACB- trigger frame from device 140 over the second frequency band, e.g., as described below.

[00383] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to receive the MACB -trigger frame from device 140 over the second frequency band, e.g., the 2,4 GHZ band, to trigger the MACB DL transmission, e.g., as described below.

[00384] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to receive from device 140 the MACB -trigger frame over the primary channel, e.g., as described below.

[00385] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to transmit the first DL transmission to device 140 over the primary channel, e.g., as described below.

[00386] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to configure the first DL transmission based on the configuration information in the MACB-trigger frame from device 102, e.g., as described above.

[00387] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to transmit a CTS-to-self frame over the primary channel based on a detection that the primary channel is idle, for example, after receipt of the MACB- trigger frame and prior to the transmission of the first DL transmission, e.g., as described below.

[00388] In some demonstrative embodiments, device 140 may receive the MACB transmission, e.g., as described below.

[00389] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to, during the MACB period, receive the MACB DL transmission over the first frequency band, for example, the 5GHz band, e.g., as described below. [00390] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to transmit, e.g., to device 102, a BA to acknowledge the first DL transmission, e.g., as described below.

[00391] In some demonstrative embodiments, device 102 may receive the BA from device 140, e.g., as described below.

[00392] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to receive the BA from device 140, for example, to acknowledge the first DL transmission, e.g., as described below.

[00393] In some demonstrative embodiments, device 160 may detect the MACB- trigger frame from device 140, e.g., as described below.

[00394] In some demonstrative embodiments, controller 174 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 160 to receive from device 140 the MACB trigger frame to indicate the MACB time period of the MACB Downlink DL transmission to device 140, e.g., as described below.

[00395] In some demonstrative embodiments, the MACB DL transmission may include at least a first DL transmission from device 160 to device 140 over a first channel of device 160 in a first frequency band, e.g., the 5GHz band, and a second DL transmission from device 102 to device 140 over a second channel in the first frequency band.

[00396] In some demonstrative embodiments, the MACB-trigger frame may be received by device 160 over the second frequency band, e.g., the 2.4GHz band, which different from the first frequency band, for example, the 5GHz band, e.g., as described below.

[00398] In some demonstrative embodiments, the MACB-trigger frame may include one or more STA-indicated channels, which are indicated by device 140, for the MACB DL transmission. [00399] In some demonstrative embodiments, the one or more STA-indicated channels may include at least the first channel of device 160 in the first frequency band.

[00401] In some demonstrative embodiments, controller 174 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 160 to configure the first DL transmission, e.g., the secondary DL transmission, based on the configuration information in the MACB -trigger frame, e.g., as described above.

[00403] In some demonstrative embodiments, controller 174 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 160 to receive a BA from device 140 to acknowledge the first DL transmission, for example, the secondary DL transmission, e.g., as described below.

[00404] Reference is made to Fig. 12, which schematically illustrates an MACB transmission 1200 with multi-band operation (MBO), in accordance with some demonstrative embodiments.

[00405] In some demonstrative embodiments, for example, as shown in Fig. 12, MACB transmission 1200 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a STA, e.g., a CE STA, which may be associated with the multiple APs.

[00406] In some demonstrative embodiments, MACB data transmission 1200 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STA0. [00407] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3.

[00408] In some demonstrative embodiments, as shown in Fig. 12, MACB transmission 1200 may be over a channel of the 2.4 GHz band, denoted "2.4Ghz", and four channels, e.g., a first channel, a second channel, a third channel and a fourth channel, of the 5GHz band, denoted "5GHz chl-ch4".

[00409] In this example, the coordinated APs and the CE-STA are able to operate at the 2.4GHz and 5GHz bands at the same time.

[00410] In some demonstrative embodiments, the master AP0, the secondary APsl-3, and/or third party devices may be configured to perform one or more operations, for example, when the master AP0 and/or the secondary APs 1-3 have data to transmit to the STA0, e.g., as described below.

[00411] In some demonstrative embodiments, the master AP (AP0) may checks its NAV setting over the 2.4GHz and 5GHz bands. If the NAV setting over the 2.4GHz and 5GHz bands are clear or reset, the master AP0 may sense the four 5Ghz channels chl-ch4 over the 5GHz band for a predefined time duration, e.g., a PIFS or any other duration, e.g., immediately preceding its backoff expiration over the 2.4GHz band.

[00412] In some demonstrative embodiments, the master AP (AP0) may perform one or more operations, for example, if the channel over the 2.4GHz band and one or more 20MHz channels chl-ch4 over the 5GHz band are idle, e.g., as described below. [00413] In one example, as shown in Fig. 12, all the channels chl-ch4 over the 5GHz band may be idle.

[00414] In some demonstrative embodiments, as shown in Fig. 12, the master AP (AP0) may send a 20 MHz MACB-RTS frame 1202 to the STA over the 2.4GHz band. [00415] In some demonstrative embodiments, the MACB-RTS frame 1202 may include specific information, for example, to indicate that one or more channels over the 5GHz band, e.g., the four 5Ghz channels chl-ch4, may be used for MACB data transmission in a following TXOP.

[00416] In some demonstrative embodiments, third party devices, which may be able to decode the MACB-RTS frame 1202 in the 2.4GHz band and may support the multi-band operation (MBO), may be required to set their NAVs over the 5GHz channels chl-ch4.

[00417] In some demonstrative embodiments, as shown in Fig. 12, the STA, e.g., the receiver of the MACB-RTS frame 1202, may monitor a CCA 1241 for the four channels chl-ch4 over the 5GHz band, e.g., after the reception of the MACB-RTS frame 1202.

[00418] In some demonstrative embodiments, as shown in Fig. 12, the STA may transmit a 20 MHz MACB -TRIGGER frame 1204 to all the coordinated APs (APs 0- 3) over the 2.4GHz band, for example, if the STA detects that one or more 20 MHz channels are available over the 5 GHz channels chl-ch4 for a predefined time duration, e.g. a SIFS or any other predefined time duration, after the reception of the MACB-RTS frame 1202.

[00419] In some demonstrative embodiments, as shown in Fig. 12, the STA may trigger AP0-AP3 to transmit DL data packets 1208 to the STA over chl-ch4, respectively, for example, if the 5GHz channels chl-ch4 are idle. [00420] In some demonstrative embodiments, the STA may only trigger AP0-AP1 to transmit DL data packets 1208 to the STA over chl-ch2, respectively, for example, if only chl and ch2 are idle.

[00421] In some demonstrative embodiments, the STA may only trigger AP0 to transmit DL data packets 1208 to the STA over chl, for example, if only chl is idle. [00422] In some demonstrative embodiments, the MACB -TRIGGER frame 1204 may include specific information to parameterize the DL MACB Data transmission.

[00423] In some demonstrative embodiments, upon the reception of the MACB- TRIGGER frame 1204, all the coordinated APs0-3, which may be identified in the MACB -TRIGGER frame 1204, may monitor their CCA 1205 over a channel on which they are assigned to transmit data packets to the STA. [00424] In some demonstrative embodiments, as shown in Fig. 12, an AP, each AP of APs 0-3, may transmit a CTS-to-self frame 1206 to reserve the channel for a DL data transmission 1208, and may send a DL data packet 1208 to the CE STA over an assigned 5GHz band channel, for example, SIFS or any other time, after an end of CTS-to-self transmission 1206, for example, if the assigned 5GHz channels are idle for a predefined time duration, e.g. DIFS or any other time, after the reception of the MACB-TRIGGER frame 1204.

[00425] In some demonstrative embodiments, upon the reception of the MACB- TRIGGER frame 1204, third party devices that can decode the MACB-TRIGGER frame 1024 and support the MBO operation may set their NAVs over the 5GHz band channels that are scheduled for the MACB data transmission.

[00426] In some demonstrative embodiments, after finishing the data transmission 1208 to the CE STA, each of the coordinated APs0-3 may monitor their CCA 1209 over the 2.4GHz band. [00427] In some demonstrative embodiments, as shown in Fig. 12, each of the coordinated APs0-3 may transmit an MACB block acknowledge request 1210 (MACB-BA Req) to the STA, and may receive a BA frame 1212 from the CE STA, e.g., to acknowledge the MACB-BA Req 1210, for example, once they access the channel over the 2.4GHz band. [00428] In one example, when an AP, e.g., AP0-3, is transmitting DL data packet 1208 to the CE STA over the 5GHz band, the AP can access the 2.4GHz band to communicate with other associated STAs at the same time.

[00429] In one example, when the AP is exchanging the MACB-BA Req. 1210 and BA frame 1212 with the CE STA over the 2.4GHz band, the AP can access the 5GHz band to communicate with other associated STAs at the same time.

[00430] In some demonstrative embodiments, as shown in Fig. 12, the MACB-RTS frame and the MACB-TRIGGER frame, may be transmitted over the 2.4GHz band, e.g., the MACB-RTS frame 1202 and the MACB-TRIGGER frame 1204.

[00431] In some demonstrative embodiments, the MACB-RTS frame and the MACB-TRIGGER may indicate the MACB data transmission over the 5Ghz band. The master AP and the CE STA can prevent third party devices that support the MBO operation from accessing the 5GHz band channels, e.g., the 5GHz chl-4. However, the master AP and the CE STA cannot prevent other third party devices that do not support MBO operation and//or the MACB data transmission from accessing the 5GHz channels during the MACB-RTS or MACB -TRIGGER frame transmission and interfering the following MACB data transmission.

[00432] In some demonstrative embodiments, the master AP and the CE STA may perform one or more operations, for example, to prevent interference of the MACB data transmission by the other third devices that do not support the MACB data transmission, e.g., as described below.

[00433] In some demonstrative embodiments, the master AP and the CE STA may transmit the MACB-RTS and MACB -TRIGGER frame, respectively, over the 2.4GHz band with a transmit power, which may enable the control frame exchange to initiate the MACB data transmission from all the coordinated APs, e.g. APs0-3, to the CE STA.

[00434] In some demonstrative embodiments, the master AP and the CE STA may transmit duplicated MACB-RTS and MACB -TRIGGER frames, respectively, over the 5GHz band with a remaining transmit power to reserve the 5GHz channels for the following MACB data transmission, e.g., from the third party devices that are near the master AP and the CE STA, e.g., as described below.

[00435] Referring back to Fig. 1, in some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to communicate one or more control frames, e.g., the MACB RTS and/or the MACB trigger frames, which may be duplicated over the 2.4 GHz and the 5GHz bands using different transmit powers, e.g., described below.

[00436] In some demonstrative embodiments, device 102 may assign different transmit powers to the MACB-RTS frames over the 2.4 GHz and the 5GHz bands, e.g., as described below.

[00437] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to assign a first transmit power for transmission of the MACB-RTS frame over the at least one idle channel in the first frequency band, e.g., the 5GHz band, and to assign a second transmit power for transmission of the MACB-RTS frame over the second frequency band, e.g., the 2.4 GHz band, e.g., as described below. [00438] In some demonstrative embodiments, the first transmit power may be less than the second transmit power, e.g., as described below.

[00439] In some demonstrative embodiments, device 140 may assign different transmit powers to the MACB -trigger frames over the 2.4 GHz and the 5GHz bands, e.g., as described below.

[00440] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to assign a first transmit power for transmission of the MACB-trigger frame over the one or more idle channels in the first frequency band, e.g., the 5GHZ band, and to assign a second transmit power for transmission of the MACB-trigger frame over the second frequency band, for example, e.g., the 2.4GHZ band, e.g., as described below.

[00441] In some demonstrative embodiments, the first transmit power may be less than the second transmit power, e.g., as described below.

[00442] Reference is made to Fig. 13, which schematically illustrates of an MACB transmission 1300 with MBO, in accordance with some demonstrative embodiments.

[00443] In some demonstrative embodiments, for example, as shown in Fig. 13, MACB transmission 1300 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a STA, e.g., a CE STA, which may be associated with the multiple APs.

[00444] In some demonstrative embodiments, MACB data transmission 1300 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STA0.

[00445] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary AP, e.g., of APs 1-3.

[00446] In some demonstrative embodiments, as shown in Fig. 13, MACB data transmission 1300 may be over a channel of the 2.4 GHz band, denoted "2.4Ghz", and four channels, e.g., a first channel, a second channel, a third channel and a fourth channel, of the 5GHz band, denoted "5GHz chl-ch4".

[00447] In this example, the coordinated APs and the CE-STA are able to operate at the 2.4GHz and 5GHz bands at the same time. [00448] In some demonstrative embodiments, the master AP0, the secondary APsl-3, and/or third party devices may be configured to perform one or more operations, for example, when the master AP0 and/or the secondary APs 1-3 have data to transmit to the STA0, e.g., as described below.

[00449] In some demonstrative embodiments, the master AP (AP0) may checks its NAV setting over the 2.4GHz and 5GHz bands. If the NAV setting over the 2.4GHz and 5GHz bands are clear or reset, the master AP0 may sense the four 5Ghz channels chl-ch4 over the 5GHz band for a predefined time duration, e.g., a PIFS or any other duration, e.g., immediately preceding its backoff expiration over the 2.4GHz band.

[00450] In some demonstrative embodiments, the master AP (AP0) may perform one or more operations, for example, if the channel over the 2.4GHz band and one or more 20MHz channels chl-ch4 over the 5GHz band are idle, e.g., as described below.

[00451] In one example, as shown in Fig. 13, all the 5Ghz channels chl-ch4 over the 5GHz band may be idle.

[00452] In some demonstrative embodiments, as shown in Fig. 13, the master AP (AP0) may transmit a 20MHz MACB-RTS frame 1302 to the STA over the 2.4GHz band.

[00453] In some demonstrative embodiments, as shown in Fig. 13, the master AP may transmit four duplicated MACB-RTS frames 1322 to the STA over the 5GHz band, for example, to reserve the 5GHz channels chl-ch4 for the following MACB data transmission from third party devices that may not support the MBO operation and/or the MACB data transmission and/or may be near the master AP and/or the STA.

[00454] In some demonstrative embodiments, as shown in Fig. 13, the master AP may assign 80% of the total transmit power over the 2.4GHz band for the MACB- RTS frame 1302. [00455] In some demonstrative embodiments, as shown in Fig. 13, the master AP may assign 20% of the total transmit power over the 5GHz band for the four duplicated MACB-RTS frames 1322.

[00456] In some demonstrative embodiments, as shown in Fig. 13, the STA may transmit a 20 MHz MACB-TRIGGER frame 1304 to the coordinated APs (APs 0-3) over the 2.4GHz band.

[00457] In some demonstrative embodiments, as shown in Fig. 13, the STA may transmit four duplicated MACB-TRIGGER frames 1344 to the coordinated APs (APs 0-3) over the 5GHz band, for example, to reserve the 5GHz channels chl-ch4 from third party devices that may not support the MACB data transmission.

[00458] In some demonstrative embodiments, as shown in Fig. 13, the STA may assign 80% of total transmit power over the 2.4GHz band for the MACB-TRIGGER frame 1304.

[00459] In some demonstrative embodiments, as shown in Fig. 13, the STA may assign 20% of total transmit power over the 5GHz band for the four duplicated MACB-TRIGGER frames 1344, for example, to reserve the 5GHz channels chl-ch4 for the following MACB data transmission from third party devices that may not support the MBO operation and/or the MACB data transmission and that may be near the master AP and/or the STA. [00460] In some demonstrative embodiments, as shown in Fig. 13, upon the reception of the MACB-TRIGGER frame 1304, all the coordinated APs0-3, which may be identified in the MACB-TRIGGER frame 1304, may monitor their CCA 1305 over a channel on which they are assigned to transmit data packets to the STA.

[00461] In some demonstrative embodiments, as shown in Fig. 13, an AP, each AP of APs 0-3 may transmit CTS-to-self frame 1306 to reserve the channel for a DL data transmission 1308 and may send a DL data packet 1308 to the CE STA over an assigned 5GHz band channel, for example, a SIFS or any other time after an end of CTS-to-self transmission 1306, for example, if the assigned 5GHz channels are idle for a predefined time duration, e.g. DIFS or any other time, after the reception of the MACB-TRIGGER frame 1304. [00462] In some demonstrative embodiments, after finishing the data transmission 1308 to the CE STA, each of the coordinated APs0-3 may monitor their CCA 1309 over the 2.4GHz band.

[00463] In some demonstrative embodiments, as shown in Fig. 13, each of the coordinated APs0-3 may transmit an MACB block acknowledge request 1310 (MACB-BA Req) to the STA, and may receive a BA frame 1312 from the CE STA, e.g., to acknowledge the MACB-BA Req 1310, for example, once they access the channel over the 2.4GHz band.

[00464] In some demonstrative embodiments, as shown above in Figs. 12 and 13, the DL data packets for the CE STA, e.g., DL data transmissions 1208 (Fig. 12), and 1308 (Fig. 13), may be transmitted over the 5GHz band, e.g., over the 5GHz channels chl-ch4.

[00465] In some demonstrative embodiments, if a CE STA is able to receive data packets over the 2.4GHz and 5GHz bands at the same time, it may be beneficial to trigger multiple APs, which are coordinated with the CE STA, to transmit the DL data packets to the STA not only over 5GHz band but also over the 2.4GHz band, for example, to improve a performance of a CE STA, e.g., as described below.

[00466] Referring back to Fig. 1, in some demonstrative embodiments, devices 102, 140, 160 and/or 180 may be configured to communicate DL data packets, for example, over both the 2.4Ghz and the 5GHz bands, e.g., described below.

[00467] In some demonstrative embodiments, device 102 may be configured to transmit the DL data packets to device 140, for example, over both the 2.4Ghz and the 5GHz bands, e.g., as described below.

[00468] In some demonstrative embodiments, controller 124 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 to process an indication in the MACB-trigger frame from device 140 that the MACB DL transmission, e.g., to device 140, is to be communicated over the first and second frequency bands, e.g., the 5GHZ and the 2.4GHZ bands, and, based on the indication, to transmit another DL transmission of the MACB DL transmission over the second frequency band, e.g., the 2.4 GHz band, e.g., as described below. [00469] In some demonstrative embodiments, device 140 may be configured to indicate to device 102 to transmit the DL data packets to device 140, for example, over both the 2.4Ghz and the 5GHz bands.

[00470] In some demonstrative embodiments, controller 154 may be configured to cause, trigger, and/or control the wireless communication station implemented by device 140 to include in the MACB -trigger frame an indication that the MACB DL transmission is to be communicated over the first and second frequency bands, e.g., the 5GHZ and the 2.4GHZ bands, and, based on the indication, to receive from device 102 the another DL transmission of the MACB DL transmission over the second frequency band, e.g., the 2.4 GHz band, e.g., as described below.

[00471] Reference is made to Fig. 14, which schematically illustrates of an MACB transmission 1400 with MBO, in accordance with some demonstrative embodiments.

[00472] In some demonstrative embodiments, for example, as shown in Fig. 14, MACB transmission 1400 may be performed between multiple APs, e.g., including a first AP denoted "AP0", a second AP, denoted "API", a third AP, denoted "AP2", a fourth AP, denoted "AP3"; and a STA, e.g., a CE STA, which may be associated with the multiple APs.

[00473] In some demonstrative embodiments, MACB data transmission 1400 may implement a definition of a master AP, e.g., AP0, and one or more secondary APs, e.g., APs 1-3, which may coordinate to serve the STA0.

[00474] In one example, device 140 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the CE STA; device 102 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, the master AP, e.g., AP0; and/or device 160 (Fig. 1) may be configured to operate as, perform a role of, and/or perform one or more functionalities of, a secondary APs, e.g., of APs 1-3.

[00475] In some demonstrative embodiments, as shown in Fig. 14, MACB data transmission 1400 may be over a channel of the 2.4 GHz band, denoted "2.4Ghz", and four channels, e.g., a first channel, a second channel, a third channel and a fourth channel, of the 5GHz band, denoted "5GHz chl-ch4".

[00476] In this example, the coordinated APs and the CE-STA are able to operate at the 2.4GHz and 5GHz bands at the same time. [00477] In some demonstrative embodiments, the master APO, the secondary APsl-3, and/or third party devices may be configured to perform one or more operations, for example, when the master APO and/or the secondary APsl-3 have data to transmit to the STA0, e.g., as described below. [00478] In some demonstrative embodiments, the master AP (APO) may check its NAV setting over the 2.4GHz and 5GHz bands. If the NAV setting over the 2.4GHz and 5GHz bands are clear or reset, the master APO may sense the four 5Ghz channels chl-ch4 over the 5GHz band for a predefined time duration, e.g., a PIFS or any other duration, for example, immediately preceding its backoff expiration over the 2.4GHz band.

[00479] In some demonstrative embodiments, the master AP (APO) may perform one or more operations, for example, if the channel over the 2.4GHz band and one or more 20MHz channels chl-ch4 over the 5GHz band are idle, e.g., as described below.

[00480] In one example, as shown in Fig. 14, all the channels chl-ch4 over the 5GHz band may be idle.

[00481] In some demonstrative embodiments, as shown in Fig. 14, the master AP (APO) may transmit a 20MHz MACB-RTS frame 1402 to the STA over the 2.4GHz band.

[00482] In some demonstrative embodiments, as shown in Fig. 14, the STA may transmit a 20 MHz MACB -TRIGGER frame 1404 to the coordinated APs (APs 0-3) over the 2.4GHz band.

[00483] In some demonstrative embodiments, if both the 2.4GHz and 5GHz band are idle at the same time, the CE STA may indicate in the MACB -TRIGGER frame 1404 that the master AP is to transmit DL data packets to the CE STA over the 2.4GHz band and 5GHz band chl.

[00484] In some demonstrative embodiments, if both the 2.4GHz and 5GHz band are idle at the same time, the CE STA may indicate in the MACB -TRIGGER frame 1404 that APs 1-3 are to transmit DL data packet to the CE STA over the 5GHz band ch2- ch4. [00485] In some demonstrative embodiments, as shown in Fig. 14, upon the reception of the MACB -TRIGGER frame 1404, the coordinated APs0-3, which may be identified in the MACB -TRIGGER frame 1404, may monitor their CCA 1405 over a channel on which they are assigned to transmit data packets to the STA.

[00486] In some demonstrative embodiments, as shown in Fig. 14, an AP, each AP of APs 0-3, may transmit a CTS-to-self frame 1406 to reserve the channel for the DL data transmission, and may send a DL data packet to the CE STA over an assigned channel, e.g., SIFS or any other time, after an end of CTS-to-self transmission 1406, for example, if the assigned channel is idle for a predefined time duration, e.g. DIFS or any other time, after the reception of the MACB -TRIGGER frame 1404.

[00487] In some demonstrative embodiments, as shown in Fig. 14, the master AP0 may transmit a DL data packet 1408 over the 2.4 GHz band and a another DL data packet 1418 over the 5GHz channel chl.

[00488] In some demonstrative embodiments, as shown in Fig. 14, an AP, each AP of APs 0-3, may transmit a DL data packet 1428 to the CE STA, for example, if the assigned 5GHz channels are idle for a predefined time duration, e.g. DIFS or any other time, after the reception of the MACB -TRIGGER frame 1404.

[00489] In some demonstrative embodiments, as shown in Fig. 14, the CE STA may transmit a block acknowledge (BA) 1419 to acknowledge data transmissions 1408, 1418 and 1428.

[00490] In some demonstrative embodiments, as shown in Fig. 14, the master AP may send DL data packet 1408 to the CE STA over the 2.4GHz band, SIFS time or any other time, after the reception of the MACB -TRIGGER frame 1404.

[00491] In some demonstrative embodiments, as shown in Fig. 14, at the same time, APsO-4 may monitor their CCA 1405 over the 5GHz band, and transmit CTS-to-self frame 1406 to reserve the channel for the following DL data transmission, e.g., if the assigned channel is idle.

[00492] In some demonstrative embodiments, as shown in Fig. 14, for example, a SIFS time or any other time, after the end of CTS-to-self transmission 1406, the APsl-3 may send the DL data packet 1428 to the CE STA over the assigned 5GHz band channel. [00493] In some demonstrative embodiments, as shown in Fig. 14, for example, a SIFS time or any other time after reception of the DL data packets 1408, 1418 and 1428 from all of the coordinated APs, the CE STA may feedback a BA frame 1419 to all of the coordinated APsO-3 over the 2.4GHz band.

[00494] In some demonstrative embodiments, after finishing the data transmissions 1408, 1418 and 1428 to the CE STA, each of the coordinated APs0-3 may monitor their CCA 1409 over the 2.4GHz band.

[00495] In some demonstrative embodiments, as shown in Fig. 14, each of the coordinated APs0-3 may transmit an MACB block acknowledge request 1410 (MACB-BA Req) to the STA, and may receive a BA frame 1412 from the CE STA, e.g., to acknowledge the MACB-BA Req 1410, for example, once they access the channel over the 2.4GHz band.

[00496] In some demonstrative embodiments, the CE STA may determine the MCS and/or resource unit (RU) that each AP of the associated APs0-3 can use to transmit the DL data packets to the STA, for example, based on the channel condition from the coordinated APs0-3 to the CE STA, the current available channel bandwidth over the 2.4GHz and/or 5GHz bands, the buffered data at all the coordinated APs for the STA, and/or any other condition.

[00497] In some demonstrative embodiments, the MCS and/or RU information may be indicated in the trigger frame 1404 sent by the CE STA to all of the coordinated APs over the 2.4GHz band. [00498] In some demonstrative embodiments, a SIFS time or any other time, after the reception of the trigger frame 1404 over 2.4GHz band, all of the coordinated APs may send DL data packets to the CE STA over an assigned RU with a selected MCS, e.g., as defined in trigger frame 1404.

[00499] Reference is made to Fig. 15, which schematically illustrates a method of MACB, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 15 may be performed by one or more elements of a system, e.g., system 100 (Fig. 1), for example, one or more wireless devices, e.g., device 102 (Fig. 1), device 140 (Fig. 1), device 160 (Fig. 1) and/or device 180 (Fig. 1), a controller, e.g., controller 124 (Fig. 1), controller 154 (Fig. 1) and/or controller 174 (Fig. 1), a radio, e.g., radio 114 (Fig. 1), radio 144 (Fig. 1) and/or radio 164 (Fig. 1), and/or a message processor, e.g., message processor 128 (Fig. 1), message processor 158 (Fig. 1) and/or message processor 178 (Fig. 1). [00500] As indicated at block 1502, the method may include sensing at a first AP an idle/busy state of a plurality of channels, the plurality of channels including a primary channel and a plurality of secondary channels. For example, controller 124 (Fig. 1) may be configured to cause, trigger, and/or control the wireless communication station implemented by device 102 (Fig. 1) to sense the idle/busy state of the plurality of channels including the primary channel and the plurality of secondary channels, e.g., as described above.

[00504] Reference is made to Fig. 16, which schematically illustrates a method of MACB, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 16 may be performed by one or more elements of a system, e.g., system 100 (Fig. 1), for example, one or more wireless devices, e.g., device 102 (Fig. 1), device 140 (Fig. 1), device 160 (Fig. 1) and/or device 180 (Fig. 1), a controller, e.g., controller 124 (Fig. 1), controller 154 (Fig. 1) and/or controller 174 (Fig. 1), a radio, e.g., radio 114 (Fig. 1), radio 144 (Fig. 1) and/or radio 164 (Fig. 1), and/or a message processor, e.g., message processor 128 (Fig. 1), message processor 158 (Fig. 1) and/or message processor 178 (Fig. 1). [00505] As indicated at block 1602, the method may include, during communication between a first AP and a first STA over a primary channel of the first AP, detect at the first AP, an MACB-trigger frame from a second STA, the MACB -trigger frame to indicate an MACB time period of an MACB DL transmission to the second STA, the MACB DL transmission including at least a first DL transmission from the first AP to the second STA over the primary channel of the first AP and a second DL transmission from a second AP to the second STA over a secondary channel of the first AP.

[00506] As indicated at block 1604, the method may include after completion of the communication with the first STA over the primary channel, transmit, during the MACB time period, the first DL transmission to the second STA over the primary channel. For example, controller 164 (Fig. 1) may be configured to cause, trigger, and/or control the wireless communication station implemented by device 160 (Fig. 1) to, after completion of the communication with device 180 (Fig. 1) over the primary channel, transmit, during the MACB time period, the first DL transmission to device 140 (Fig. 1) over the primary channel, e.g., as described above.

[00507] Reference is made to Fig. 17, which schematically illustrates a method of MACB, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 17 may be performed by one or more elements of a system, e.g., system 100 (Fig. 1), for example, one or more wireless devices, e.g., device 102 (Fig. 1), device 140 (Fig. 1), device 160 (Fig. 1) and/or device 180 (Fig. 1), a controller, e.g., controller 124 (Fig. 1), controller 154 (Fig. 1) and/or controller 174 (Fig. 1), a radio, e.g., radio 114 (Fig. 1), radio 144 (Fig. 1) and/or radio 164 (Fig. 1), and/or a message processor, e.g., message processor 128 (Fig. 1), message processor 158 (Fig. 1) and/or message processor 178 (Fig. 1).
