Abstract

For example, an Access Point (AP) may be configured to transmit a Synchronized Transmit Opportunity (S-TxOP) trigger to initiate an S-TxOP. For example, the S-TxOP may include a plurality of transmission slots synchronized based on the S-TxOP trigger, wherein the plurality of transmission slots may be configured for communication between the AP and one or more scheduled wireless communication stations (STAs). For example, a transmission slot of the plurality of transmission slots may include one or more blanked Orthogonal-Frequency-Division-Multiplexing (OFDM) symbols at an end of the transmission slot. For example, the one or more blanked OFDM symbols may be reserved for time-sensitive communications. For example, the AP may be configured to communicate a time-sensitive transmission with a time-sensitive STA during at least one blanked OFDM symbol of the one or more blanked OFDM symbols.

[00122] For example, as shown in Fig. 3, multi-link AP logical entity 302 may include a multi-band AP MLD, which may be configured to communicate over a plurality of wireless communication frequency bands. For example, as shown in Fig. 3, AP STA 312 may be configured to communicate over a 2.4GHz frequency band, AP STA 314 may be configured to communicate over a 5GHz frequency band, and/or AP STA 316 may be configured to communicate over a 6GHz frequency band.

[00123] Referring back to Fig. 1, in some demonstrative aspects, devices 102, 140 and/or 150 may be configured to support wireless communication according to a Synchronized Transmit Opportunity (S-TxOP) mechanism, e.g., as described below.

[00124] In some demonstrative aspects, the S-TxOP mechanism may be configured to provide a technical solution to support ultra-low latency communication within a TxOP obtained by an AP.

[00125] For example, an S-TxOP may be configured to provide a technical solution to support Downlink (DL) and/or Uplink (UL) data communication, for example, with a low control overhead.

[00126] For example, one or more communications during the S-TxOP may be configured to utilize a preamble format, which may be configured to support a technical solution for optimizing a preamble length, for example, to support low control overhead during the S-TxOP, e.g., as described below.

[00127] For example, one or more communications during the S-TxOP may be configured to utilize a resource allocation signaling mechanism, which may be configured to support a technical solution, for example, to support low control overhead during the S-TxOP, e.g., as described below. [00128] For example, one or more communications during the S-TxOP may be configured to utilize an acknowledgement scheme, which may be configured to support a technical solution for supporting a lightweight acknowledgement, for example, to support low control overhead during the S-TxOP, e.g., as described below.

[00129] Reference is made to Fig. 4, which schematically illustrates communications during an S-TxOP 400, which may be implemented in accordance with some demonstrative aspects.

[00130] In some demonstrative aspects, an AP, e.g., an AP implemented by device 102 (Fig. 1), may be configured to communicate with one or more STAs, e.g., a STA implemented by device 140 (Fig. 1) and/or a STA implemented by device 150 (Fig. 1), over a wireless communication channel during the S-TxOP 400, e.g., as described below.

[00131] For example, as shown in Fig. 4, the S-TxOP 400 may be configured to include an S-TXOP trigger phase, during which one or more Physical layer Protocol Data Units (PPDUs) and/or frames may be communicated by the AP and the one or more STAs participating in the S-TxOP 400.

[00132] For example, the one or more PPDUs and/or frames communicated during the S-TXOP trigger phase may be configured to support synchronization between one or more STAs participating in the S-TXOP 400 to synchronize to the AP.

[00133] For example, the one or more PPDUs and/or frames communicated during the S-TXOP trigger phase may be configured to support the AP in signaling to the one or more STAs participating in the S-TXOP 400 which slots are scheduled to which STAs for communication during the S-TXOP 400.

[00134] For example, the one or more PPDUs and/or frames communicated during the S-TXOP trigger phase may be configured to support the AP in signaling to the one or more STAs participating in the S-TXOP 400 resource allocations corresponding to the slots scheduled for communication during the S-TXOP 400.

[00135] For example, as shown in Fig. 4, an AP, e.g., the AP implemented by device 102 (Fig. 1), may be configured to transmit an S-TxOP trigger frame 402, for example, during the S-TXOP Trigger phase, e.g., as described below. [00136] For example, as shown in Fig. 4, the AP, e.g., the AP implemented by device 102 (Fig. 1), may be configured to communicate the S-TxOP trigger frame 402 with one or more STAs, e.g., including the STA implemented by device 140 (Fig. 1) and/or including the STA implemented by device 150 (Fig. 1), for example, to initiate the S- TxOP 400, e.g., as described below.

[00137] For example, a preamble, e.g., a modified legacy preamble, of the S-TxOP trigger frame 402 may be used to trigger multiple transmissions, e.g., UL and/or DL transmissions. One or more fields and/or portions in the S-TxOP trigger frame 402, e.g., the preamble and/or one or more other portions of the S-TXOP trigger frame 402, may be configured to include information to notify each of the stations involved in the transmission when they are expected to transmit and/or receive data during the S-TXOP 400.

[00138] In some demonstrative aspects, the S-TxOP 400 may be configured utilizing a preamble, e.g., a single modified legacy preamble, which may include resource allocation signaling, e.g., optimized resource allocation signaling, for example, to support semi-static scheduling.

[00139] For example, a single preamble may be utilized for resource allocation signaling for the whole duration of the S-TxOP 400, for example, to provide a technical solution to support a highly efficient and/or low latency transmission of data packets.

[00140] For example, the S-TxOP 400 may be utilized to provide a technical solution to support a highly efficient and/or low latency transmission of relatively small data packets, e.g., with a size of about 100 bytes and/or any other size, which may be, for example, transmitted periodically.

[00141] In some demonstrative aspects, the S-TxOP 400 may be configured to support a combination of UL and DL time slots in the S-TXOP duration, for example, to facilitates immediate acknowledgement of successful UL and/or DL transmissions, e.g., as described below.

[00142] For example, as shown in Fig. 4, the S-TxOP trigger frame 402 may include a sync field 401, for example, to synchronize one or more STAs to the AP. For example, the sync field 401 may include synchronization information to synchronize the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1) to the AP implemented by device 102 (Fig. 1).

[00143] For example, as shown in Fig. 4, the S-TxOP trigger frame 402 may include a STA Info list field 403. For example, the STA Info list field 403 may include information regarding the one or more STAs to participate in the S-TxOP 400.

[00144] For example, as shown in Fig. 4, the S-TxOP trigger frame 402 may include a scheduling information field 405. For example, the scheduling information field 405 may include transmit configuration information regarding transmission slots to be scheduled during the S-TxOP 400.

[00145] For example, as shown in Fig. 4, the S-TxOP 400 may include a plurality of low-overhead (LO) transmission (Tx) (LO-Tx) slots 420, e.g., as described below. For example, the S-TxOP trigger frame 402 may be configured to schedule the LO-Tx slots 420.

[00146] For example, the plurality of LO transmission slots 420 may be synchronized, for example, based on the S-TxOP trigger frame 402.

[00147] For example, as shown in Fig. 4, two consecutive LO-Tx slots 420, e.g., each pair of consecutive LO-Tx slots 420, may be separated by a Short Interframe Space (SIFS) from one another.

[00148] For example, as shown in Fig. 4, the LO-Tx slots 420 may include one or more DL LO-Tx slots, which may be scheduled for DL transmissions, for example, from the AP to the one or more STAs.

[00149] For example, as shown in Fig. 4, the LO-Tx slots 420 may include one or more UL LO-Tx slots, which may be scheduled for UL transmissions, for example, the one or more STAs to the AP.

[00150] For example, as shown in Fig. 4, the AP, e.g., the AP implemented by device 102 (Fig. 1), may be configured to transmit at least one LO DL PPDU 407, for example, during a DL LO-Tx slot 404 of the plurality of LO-Tx slots 420.

[00151] For example, the AP, e.g., the AP implemented by device 102, (Fig. 1), may be configured to transmit the LO DL PPDU 407 to one or more STAs, e.g., including the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1).

[00152] For example, as shown in Fig. 4, the LO DL PPDU 407 may include a low- overhead preamble (LP) (also referred to as “lite preamble”) 408, and a DL Data field 410.

[00153] For example, as shown in Fig. 4, a STA addressed by the LO DL PPDU 407, e.g., the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1), may be configured to transmit to the AP an UL acknowledgement (ACK) frame 409, for example, during the LO-Tx slot 404, e.g., as described below.

[00154] For example, the UL ACK frame 409 may be configured to acknowledge receipt of the LO DL PPDU 407 by the STA.

[00155] For example, as shown in Fig. 4, the UL ACK frame 409 may be after the LO DL PPDU 407, for example, no more than a SIFS after the LO DL PPDU 407.

[00156] For example, as shown in Fig. 4, a STA participating in the S-TxOP 400, e.g., the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1), may be configured to transmit a LO UL PPDU 413 to the AP, for example, during a LO-Tx slot 406 of the plurality of LO transmission slots 420.

[00157] For example, the AP implemented by device 102 (Fig. 1) may be configured to receive the LO UL PPDU 413 from the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1).

[00158] For example, as shown in Fig. 4, the AP implemented by device 102 (Fig. 1) may be configured to transmit a low overhead trigger (also referred to as “lite trigger”) (L-Trigger) frame 411 during the LO transmission slot 406, for example, to trigger transmission of the LO UL PPDU 413.

[00159] For example, the AP implemented by device 102 (Fig. 1) may be configured to transmit L-Trigger frame 411 to trigger the transmission of the LO UL PPDU 413 from the STA implemented by device 140 (Fig. 1) and/or the STA implemented by device 150 (Fig. 1).

[00160] For example, as shown in Fig. 4, the LO UL PPDU 413 may include an LP 412, and an UL Data field 414. [00161] For example, as shown in Fig. 4, the LO UL PPDU 413 may be after the L- Trigger frame 411, for example, no more than a SIFS after the L-Trigger frame 411.

[00162] For example, as shown in Fig. 4, the AP, e.g., the AP implemented by device 102 (Fig. 1), may be configured to transmit to the STA a DL ACK frame 415, for example, during the LO-Tx slot 406.

[00163] For example, the DL ACK frame 415 may be configured to acknowledge receipt of the LO UL PPDU 413 by the AP.

[00164] For example, as shown in Fig. 4, the DL ACK frame 415 may be after the LO UL PPDU 413, for example, no more than a SIFS after the LO UL PPDU 413.

In other aspects, devices 102, 140 and/or 150 may be configured to perform any other additional and/or alternative operations and/or communications according to any other S-TxOP mechanism.

[00175] In some demonstrative aspects, devices 102, 140 and/or 150 may be configured to communicate wireless transmissions based on the S-TxOP scheme, e.g., the S-TxOP scheme of Fig. 4, for example, to provide a technical solution utilizing placeholders for a low latency transmission, for example, with controlled minimum latency, for example, even during an ongoing over-the-air packet transmission, e.g., as described below.

[00176] In some demonstrative aspects, devices 102, 140 and/or 150 may be configured to communicate wireless transmissions based on the S-TxOP scheme, e.g., the S-TxOP scheme of Fig. 4, for example, to provide a technical solution utilizing synchronization and/or tracking mechanisms, which may be implemented by an AP, e.g., an AP implemented by device 102, and one or more NOMA stations, e.g., a NOMA station implemented by device 140.

[00177] In some demonstrative aspects, devices 102, 140 and/or 150 may be configured to communicate wireless transmissions based on a synchronization mechanism, which may be configured to provide a technical solution to support successful reception of both an ongoing packet and an urgent NOMA transmissions at the AP, e.g., as described below.

[00178] In some demonstrative aspects, the synchronization mechanism may be configured to provide a technical solution to support the NOMA stations in performing an OFDM-synchronized transmission.

[00179] In some demonstrative aspects, devices 102, 140 and/or 150 may be configured to communicate wireless transmissions based on the S-TxOP scheme, e.g., the S-TxOP scheme of Fig. 4, for example, to provide a technical solution to support an orthogonal transmission, for example, from client stations, e.g., NOMA stations and/or any other type of station, for example, to an AP, e.g., as described below.

[00180] In some demonstrative aspects, devices 102, 140 and/or 150 may be configured to communicate wireless transmissions based on the S-TxOP scheme, e.g., the S-TxOP scheme of Fig. 4, for example, to provide a technical solution to support a reduction in efficient implementation complexity, e.g., as described below.

[00181] In some demonstrative aspects, it may be defined that an AP device, e.g., an AP implemented by device 102, is to assign blanked OFDM symbols for urgent UL transmission, e.g., as described below.

[00182] In some demonstrative aspects, the AP device, e.g., the AP implemented by device 102, may be configured to assign the blanked OFDM symbols within an S-TxOP slotted transmission, for example, according to the S-TxOP scheme of Fig. 4, e.g., as described below.

[00183] In some demonstrative aspects, the AP device, e.g., the AP implemented by device 102, may be configured to assign one or more OFDM symbols, for example, one or more last few OFDM symbols or part of them, for example, by using an OFDMA structure of a slot, e.g., each slot, in the S-TxOP for transmission of urgent traffic, for example, UL urgent traffic, e.g., as described below.

[00184] In some demonstrative aspects, for example, as shown in Fig 4., the AP device, e.g., the AP implemented by device 102, may be configured to assign one or more transmission slots 420 (Fig. 4) for communication between the AP device, e.g., the AP implemented by device 102, and one or scheduled STAs, e.g., a STA implemented by device 150, e.g., as described below.

[00185] In some demonstrative aspects, as shown in Fig. 4, the AP device, e.g., the AP implemented by device 102, may be configured to assign the one or more transmission slots 420 (Fig. 4) to include one or more blanked OFDM symbols 425 (Fig. 4), which may be reserved for time-sensitive, e.g., urgent, communications between the AP device, e.g., the AP implemented by device 102, and one or more time- sensitive STAs, for example, a STA implemented by device 140, e.g., as described below.

[00186] In some demonstrative aspects, the AP device, e.g., the AP implemented by device 102, may be configured to allocate one or more blanked OFDM symbol 425 (Fig. 4) for a time- sensitive transmission, e.g., as described below.

[00187] In one example, one or more blanked OFDM symbols 425 (Fig. 4) may be allocated for an UL time- sensitive transmission, e.g., as described below.

[00188] In another example, one or more blanked OFDM symbols 425 (Fig. 4) may be allocated for a DL time-sensitive transmission, e.g., as described below.

[00189] In some demonstrative aspects, the last few OFDM symbols of the one or more transmission slots 420 (Fig. 4) may be used as blanked OFDM symbols 425 (Fig. 4), for example, instead of symbols within each frame transmission.

[00190] In some demonstrative aspects, allocating the last few OFDM symbols of the one or more transmission slots 420 (Fig. 4) as blanked OFDM symbols 425 (Fig. 4) may provide a technical solution to support ease of tracking at a receiver of regular traffic. For example, it may be inefficient to allocate blanked symbols in a middle of a frame, for example, in case of a long frame, e.g., in a TxOP of about 5-8 milliseconds (msec). For example, scheduling blanked symbols in the middle of a frame may interrupt reception of regular packets following the blank symbols, e.g., once the urgent traffic is over. In one example, pilots may be inserted for the regular packets, for example, to enable continuous tracking. However, as a transmission slot in an S-TxOP may be relatively short, e.g., in an order of hundredths of microseconds (us), blanking the last few OFDM symbols may be sufficient to meet latency requirements.

[00191] In some demonstrative aspects, device 102, device 140, and/or device 150 may be configured to communicate a transmission based on an S-TxOP scheme utilizing blanked OFDM symbols, e.g., blanked OFDM symbols 425 (Fig. 4), to provide a technical solution to support an ULL transmission, e.g., in accordance with the IEEE 802.11 protocol, for example, while considering the complexity of implementation at the client stations and/or at the AP.

[00192] In some demonstrative aspects, device 102, device 140, and/or device 150 may be configured to communicate the transmission based on the S-TxOP scheme utilizing the blanked OFDM symbols, e.g., blanked OFDM symbols 425 (Fig. 4), to provide a technical solution to support utilizing a frame format and/or operation of the IEEE 802.11 protocol, for example, to enable a backward compatible solution that can coexist, for example, with a current protocol.

[00193] In some demonstrative aspects, device 102, device 140, and/or device 150 may be configured to communicate the transmission based on the S-TxOP scheme utilizing the blanked OFDM symbols, e.g., blanked OFDM symbols 425 (Fig. 4), to provide a technical solution to support a Wireless Time Sensitive Network (WTSN), for example, in Wi-Fi networks.

[00194] In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct an AP implemented by device 102 to transmit an S-TxOP trigger to initiate an S-TxOP, e.g., as described below.

[00195] In some demonstrative aspects, the S-TxOP may include a plurality of transmission slots synchronized based on the S-TxOP trigger, e.g., as described below.

[00196] In some demonstrative aspects, the plurality of transmission slots may be configured for communication between the AP and one or more scheduled STAs, e.g., as described below.

[00197] For example, an AP device, e.g., an AP implemented by device 102, may transmit S-TxOP trigger 402 (Fig. 4) to initiate S-TxOP 400 (Fig. 4) including a plurality of transmission slots 420 (Fig. 4) configured for communication between device 102 and one or more scheduled STAs, e.g., including a scheduled STA implemented by device 150.

[00215] In other aspects, any other configuration of the blanked OFDM symbols in a transmission slot may be implemented. For example, any other count of blanked OFDM symbols per transmission slot, any other duration of blanked OFDM symbols per transmission slot, and/or any other additional parameter corresponding to the blanked OFDM symbols may be implemented. [00216] In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct the AP implemented by device 102 to communicate a time-sensitive transmission with a time- sensitive STA, for example, during at least one blanked OFDM symbol of the one or more blanked OFDM symbols, e.g., as described below.

[00217] For example, the AP device, e.g., the AP implemented by device 102, may communicate a time-sensitive transmission with a time-sensitive STA, e.g., a timesensitive STA implemented by device 140, during at least one blanked OFDM symbol of the one or more blanked OFDM symbols 425 (Fig. 4).

[00218] In some demonstrative aspects, the time- sensitive STA may include an Ultra- Low-Latency (ULL) STA.

[00219] In other aspects, the time-sensitive STA may include any other type of STA.

[00220] In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct the AP implemented by device 102 to configure the S- TxOP trigger transmitted by device 102 to include scheduling information to schedule the one or more blanked OFDM symbols at the end of the transmission slot, e.g., as described below.

[00256] In some demonstrative aspects, a total duration of the one or more blanked OFDM symbols in a transmission slot may be configured to be no more than 5% of a duration of the transmission slot, e.g., as described above.

[00257] In some demonstrative aspects, a total duration of the one or more blanked OFDM symbols in a transmission slot may be configured to be no more than 3% of a duration of the transmission slot, e.g., as described above. [00258] In some demonstrative aspects, a duration of the transmission slot may be configured to be less than 1 millisecond (ms), and/or a total duration of the one or more blanked OFDM symbols may be configured to be less than 100 us, e.g., as described above.

[00259] In other aspects, any other configuration of the blanked OFDM symbols in a transmission slot may be implemented. For example, any other count of blanked OFDM symbols per transmission slot, any other duration of blanked OFDM symbols per transmission slot, and/or any other additional parameter corresponding to the blanked OFDM symbols may be implemented.

[00260] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to communicate a time-sensitive transmission with the AP during at least one blanked OFDM symbol of the one or more blanked OFDM symbols, e.g., as described below.

[00261] For example, controller 154 may be configured to control, trigger, cause, and/or instruct a STA implemented by device 140 to communicate a time-sensitive transmission with the AP implemented by device 102, for example, during at least one blanked OFDM symbol of the one or more blanked OFDM symbols 425 (Fig. 4).

[00262] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to negotiate with the AP an allocation of one or more reserved RUs in the one or more blanked OFDM symbols, for example, at the end of the transmission slot, e.g., as described below.

[00263] In some demonstrative aspects, the one or more reserved RUs may be configured to be reserved for communication of the time-sensitive transmission between the STA implemented by device 140 and the AP, e.g., as described above.

[00264] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to transmit an UL time-sensitive transmission to the AP, for example, during the at least one blanked OFDM symbol, e.g., as described below.

[00265] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to encode the UL time-sensitive transmission, for example, based on a pre-assigned orthogonal code sequence, e.g., as described below.

[00266] In some demonstrative aspects, the pre-assigned orthogonal code sequence may include a Zadoff-Chu sequence, e.g., as described below.

[00267] In other aspects, the pre-assigned orthogonal code sequence may include any other additional or alternative type of sequence.

[00268] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to transmit the UL time-sensitive transmission to indicate an UL request from the STA tot eh AP, e.g., as described below.

[00269] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to transmit an UL data transmission to the AP, for example, based on an UL trigger from the AP, e.g., as described below.

[00270] In some demonstrative aspects, an orthogonal and/or semi-orthogonal transmission, e.g., by means of CDMA and/or any other technique, may be implemented, for example, to support UL transmission by time- sensitive stations, e.g., the STA implemented by device 140.

[00271] In some demonstrative aspects, a time- sensitive STA, e.g., the STA implemented by device 140, may be configured to select, e.g., to randomly select, a sequence, e.g., a Zadoff-Chu sequence or any other type of sequence, for example, from a pool of predefined, e.g., pre-assigned, sequences. For example, the pre-assigned sequences may be assigned to a plurality of time- sensitive STAs by an AP device, e.g., the AP implemented by device 102.

[00272] In other aspects, any other orthogonal or semi-orthogonal sequences may be implemented.

[00273] In some demonstrative aspects, these orthogonal and/or semi-orthogonal sequences may be implemented to provide a technical solution to simplify an implementation of an AP receiver and/or to support optional features for different market segments. For example, in case of deployments including a relatively small number of devices, e.g., in an order of 10’ s of devices, with potential ultra-urgent transmission, relatively less-expensive APs may be implemented, for example, to receive and decode the orthogonal or semi-orthogonal signals. For example, in case deployments including a relatively small number of devices, e.g., in an order of 100’s of devices, more expensive APs may be implemented, for example, with more complex receivers, which may be able to decode NOMA signals, e.g., more efficiently and/or accurately.

[00274] In some demonstrative aspects, a time-sensitive STA having urgent traffic, e.g., the STA implemented by device 140, may be configured to send a code, for example a CDMA code, e.g., a Zadoff Chu code and/or a Zadoff Chu sequence, in a blanked OFDM symbol of an S-TxOP transmission slot, e.g., blanked OFDM symbol 425 (Fig. 4), to request being scheduled for an UL transmission, for example, in a next S-TXOP transmission slot.

[00275] In some demonstrative aspects, the code may be configured to indicate a couple of bits of information to the AP, for example, including information relating to the UL traffic to be transmitted from the time-sensitive STA.

[00276] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to identify a DL time-sensitive transmission from the AP, for example, during the at least one blanked OFDM symbol, e.g., as described below.

[00277] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to determine, for example, based on an indication from the AP, that padding is not to be applied following an end of a packet transmitted in the transmission slot including the one or more blanked OFDM symbols, e.g., as described above.

[00278] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to determine, for example, based on an indication from the AP, that post-FEC padding is not to be applied in the transmission slot including the one or more blanked OFDM symbols, e.g., as described above.

[00279] In some demonstrative aspects, the AP, e.g., the AP implemented by device 102, may dedicate the last few OFDM symbols in a transmission slot of the transmission slots 420 (Fig. 4) as the blanked OFDM symbols 425 (Fig. 4), which may be dedicated for the time- sensitive, e.g., urgent, transmission if any station needs to transmit urgent traffic.

[00280] In some demonstrative aspects, an AP, e.g., an AP implemented by device 102, may be configured to indicate to STAs participating in the S-TxOP 400 (Fig. 4) that the last few OFDM symbols in the transmission slot of the transmission slots 420 (Fig. 4), which are to be allocated as blanked OFDM symbols 425 (Fig. 4), are not to be used for post-FEC padding.

[00281] In some demonstrative aspects, the AP, e.g., the AP implemented by device 102, may be configured to indicate that no padding is needed for regular transmissions during the S-TxOP 400 (Fig. 4). For example, the AP may configure a bit/field in a trigger slot, e.g., S-TxOP trigger 402 (Fig. 4), to indicate that no padding is to be applied during the transmission of regular traffic.

[00282] In some demonstrative aspects, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to determine, for example, based on the S-TxOP trigger from the AP implemented by device 102, an allocation of a mostly-blanked transmission slot in the plurality of transmission slots, e.g., as described above.

[00283] For example, controller 154 may be configured to control, trigger, cause, and/or instruct the STA implemented by device 140 to identify that at least 50% of RUs of the mostly -blanked transmission slot are blanked RUs reserved for the time-sensitive communications, e.g., as described above.

[00284] In some demonstrative aspects, the duration of blanked OFDM symbols, e.g., a length of one or more blanked OFDM symbols, may be different in different OFDM A RUs.

[00285] In some demonstrative aspects, transmission of urgent traffic may be orthogonalized in a frequency domain. For example, details of scheduling information may be indicated in a trigger slot, e.g., S-TxOP trigger 402 (Fig. 4). For example, stations with urgent traffic, e.g., time- sensitive STAs, may decode the details of the scheduling information e.g., from the S-TxOP trigger 402 (Fig. 4). For example, the stations with urgent traffic, e.g., time- sensitive STAs, may and synchronize with a DL and/or an UL frame in the S-TXOP, where the transmitter of urgent traffic may obtain the details of the scheduling information from the trigger frame.

[00286] In some demonstrative aspects, it may be defined that an AP, e.g., the AP implemented by device 102, may negotiate, e.g., pre-negotiate, with a time sensitive STA having urgent traffic to transmit, e.g., the time- sensitive STA implemented by device 140, one or more certain RUs to be reserved for time-sensitive communication of the time sensitive STA, for example, in the last few blanked OFDM symbols of a transmission slot in the S-TxOP. For example, the AP and the time-sensitive STA may pre-negotiate the RUs to be reserved, for example, prior to the S-TxOP. For example, the AP and the time- sensitive STA may pre-negotiate the RUs to be reserved, for example, to provide a technical solution to support scheduling of the RUs to be reserved, for example, without having the S-TxOP trigger carry the scheduling information of the urgent traffic.

[00287] In some demonstrative aspects, device 102, device 140, and/or device 150 may be configured to utilize one or more almost-blanked slots in an S-TxOP, for example, in addition to the blanked OFDM symbols, e.g., the blanked last few OFDM symbols, in the transmission slot of the S-TxOP, e.g., as described below.

[00288] In some demonstrative aspects, it may be defined that an AP, e.g., an AP implemented by device 102, may be allowed to allocate an almost-blanked slot, which may be configured to blank an entire slot in an S-TxOP, for example, except for one or more RU allocations that are periodically and deterministically pre-assigned. For example, one or more RU allocations may be periodically and deterministically preassigned for time-sensitive, e.g., urgent, transmissions, for example, for heart-beat transmissions, e.g., from programmable logic controller (PLC) devices.

[00289] In some demonstrative aspects, the AP, e.g., the AP implemented by device 102, may be configured to allocate a slot as an “almost-blanked slot”, for example, based on some deterministic/periodic traffic to scheduled, e.g., with regular stations.

[00290] In some demonstrative aspects, the almost-blanked slots may be implemented to provide a technical solution to support an allocation, which may be pre-defined or pre-negotiated by the AP, and, accordingly, may support reducing the overhead of scheduling information in the trigger slot. [00291] In one example, for example, in an industrial usage scenario, robots may operate on a 2msec cycle for task level control, e.g., sensing/camera input/UL/compute/actuation/DL; machine tools/control panels may operate on 250 to 500 usee cycles, e.g., UL/DL within 1 cycle; HMI flow of 1 heartbeat pkt every 1 msec for safety, e.g., e-stop activated if more than x packets miss the deadline; Augmented Reality (AR) traffic may include Head Mounted Display (HMD) periodic status (UL), depth maps (UL event triggered), DL video with -10 msec cycle; and/or IT devices may generate background traffic. According to this example, the AP may be configured to schedule one or more almost-blanked slots for urgent UL transmission in an S-TxOP, for example, while accounting for the periodic communications of the various devices.

[00292] In some demonstrative aspects, device 102, device 140, and/or device 150 may be configured to implement blanked OFDM symbols in an S-TxOP, e.g., blanked OFDM symbols 425 (Fig. 4) in the S-TxOP 400 (Fig. 4), to support one or more operations at the time-sensitive, e.g., urgent, STAs, and/or scheduled, e.g., regular, STAs.

[00293] In some demonstrative aspects, the time-sensitive STAs, e.g., the STA implemented by device 140, may be configured to monitor ongoing traffic, for example, to learn where/when the blanked OFDM symbols are available. For example, the timesensitive STAs may learn where/when the blanked OFDM symbols are available, for example, by decoding the trigger portion of the S-TXOP, e.g., S-TxOP trigger 402 (Fig. 4).

[00294] In some demonstrative aspects, as part of monitoring the ongoing traffic, a time-sensitive STA, e.g., the time-sensitive STA implemented by device 140, may, e.g., shall, obtain a blanked OFDM symbol boundary and/or a post-FEC padding duration in different RUs. For example, the time- sensitive STA may estimate its frequency/timing offsets relative to the ongoing transmission, and may pre-correct for it.

[00295] In some demonstrative aspects, it may be defined that in a blanked OFDM symbol, e.g., at any given blanked OFDM symbol, more than one time- sensitive STA may transmit a code/signature, e.g., a randomly selected or pre-assigned code/signature, of the time- sensitive STA, for example, in a pre-assigned RU, or over an entire bandwidth. For example, an AP, e.g., an AP implemented by device 102, may be able to perform an UL detection and/or decoding of urgent packets, for example, by configuring the AP to know where to stop receive/transmit regular packets, e.g., during the allocated blanked OFDM symbols.

[00296] In some demonstrative aspects, scheduled, e.g., regular, STAs may be aware of the location of the blanked OFDM symbols, e.g., blanked OFDM symbols 425 (Fig. 4), and/or post-FEC padding. In one example, it may be defined that the scheduled STAs are not to transmit/receive any more data on the blanked OFDM symbols. In another example, it may be defined that the padding part is to be filled by a known data, e.g., a known pattern, for example, to enable the AP to easily decode and/or separate the padding part from an urgent transmission.

[00297] In some demonstrative aspects, blanked OFDM symbols may be allocated in an S-TxOP, e.g., blanked OFDM symbols 425 (Fig. 4) in the S-TxOP 400 (Fig. 4) as described above, for example, to provide a technical solution to support OFDM- boundary level synchronization for urgent traffic.

[00298] In some demonstrative aspects, blanked OFDM symbols may be allocated in an S-TxOP, e.g., blanked OFDM symbols 425 (Fig. 4) in the S-TxOP 400 (Fig. 4) as described above, for example, to provide a technical solution, which does not require performing traffic for the regular transmissions as they have ended.

[00299] In some demonstrative aspects, blanked OFDM symbols may be allocated in an S-TxOP, e.g., blanked OFDM symbols 425 (Fig. 4) in the S-TxOP 400 (Fig. 4) as described above, for example, to provide a technical solution to support an AP, e.g., an AP implemented by device 102, to control a delay in transmission of time- sensitive, e.g., urgent, packets, for example, through selecting a size of each transmission slot within the S-TXOP.

[00300] In some demonstrative aspects, blanked OFDM symbols may be allocated in an S-TxOP, e.g., blanked OFDM symbols 425 (Fig. 4) in the S-TxOP 400 (Fig. 4) as described above, for example, to provide a technical solution to support, which may be utilized in both DL and UL slots. For example, it may be defined that an AP is to be required to immediately switch to a receive mode, for example, to detect and decode ULL urgent traffic, for example, when utilizing blanked OFDM symbols in a DL slot during the S-TxOP. [00301] Reference is made to Fig. 5, which schematically illustrates a method of wireless communication during an S-TxOP, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 5 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), and/or device 140 (Fig. 1), a controller, e.g., controller 124 (Fig. 1) and/or controller 154 (Fig. 1), a radio, e.g., radio 114 (Fig. 1) and/or radio 144 (Fig. 1), and/or a message processor, e.g., message processor 128 (Fig. 1) and/or message processor 158 (Fig. 1).

[00302] As indicated at block 502, the method may include transmitting from an AP an S-TxOP trigger to initiate an S-TxOP. For example, the S-TxOP may include a plurality of transmission slots synchronized based on the S-TxOP trigger. For example, the plurality of transmission slots may be configured for communication between the AP and one or more scheduled STAs. For example, a transmission slot of the plurality of transmission slots may include one or more blanked OFDM symbols at an end of the transmission slot. For example, the one or more blanked OFDM symbols may be reserved for time-sensitive communications. For example, controller 124 (Fig. 1) may be configured to cause, trigger, and/or control device 102 (Fig. 1) to transmit the S- TxOP trigger to initiate the S-TxOP, which includes the one or more blanked OFDM symbols to be reserved for time-sensitive communications, e.g., as described above.

[00303] As indicated at block 504, the method may include communicating a timesensitive transmission with a time-sensitive STA during at least one blanked OFDM symbol of the one or more blanked OFDM symbols. For example, controller 124 (Fig. 1) may be configured to cause, trigger, and/or control device 102 (Fig. 1) to communicate the time-sensitive transmission with device 140 (Fig. 1) during at least one blanked OFDM symbol of the one or more blanked OFDM symbols, e.g., as described above.

[00304] Reference is made to Fig. 6, which schematically illustrates a method of wireless communication during an S-TxOP, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of Fig. 11 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), and/or device 140 (Fig. 1), a controller, e.g., controller 124 (Fig. 1) and/or controller 154 (Fig. 1), a radio, e.g., radio 114 (Fig. 1) and/or radio 144 (Fig. 1), and/or a message processor, e.g., message processor 128 (Fig. 1) and/or message processor 158 (Fig. 1).

[00305] As indicated at block 602, the method may include processing at a STA an S- TxOP trigger from an AP to initiate an S-TxOP. For example, the S-TxOP may include a plurality of transmission slots synchronized based on the S-TxOP trigger. For example, the plurality of transmission slots may be configured for communication between the AP and one or more scheduled STAs. For example, a transmission slot of the plurality of transmission slots may include one or more blanked OFDM symbols at an end of the transmission slot. For example, the one or more blanked OFDM symbols may be reserved for time-sensitive communications. For example, controller 154 (Fig. 1) may be configured to cause, trigger, and/or control device 140 (Fig. 1) to process the S-TxOP trigger received from device 102 (Fig. 1) to initiate the S-TxOP, which includes the one or more blanked OFDM symbols to be reserved for time- sensitive communications, e.g., as described above.

[00306] As indicated at block 604, the method may include communicating a timesensitive transmission with the AP during at least one blanked OFDM symbol of the one or more blanked OFDM symbols. For example, controller 154 (Fig. 1) may be configured to cause, trigger, and/or control device 140 (Fig. 1) to communicate the time-sensitive transmission with device 102 (Fig. 1) during at least one blanked OFDM symbol of the one or more blanked OFDM symbols, e.g., as described above.
