In some demonstrative aspects, the EHT MU PPDU may include a PPDU that carries one or more PHY service data units (PSDUs) for one or more STAs using a downlink multi-user multiple input, multiple output (DL-MU-MIMO) technique, an orthogonal frequency division multiple access (DL OFDMA) technique, or a combination of the two techniques.


In some demonstrative aspects, for example, devices 102, 140 and/or 160 may be configured to perform one or more operations, and/or functionalities of an EHT STA, which may be configured, for example, to generate, transmit, receive and/or process the EHT MU PPDU, for example, over a 20 MHz channel width, a 40 MHz channel width, a 80 MHz channel width, a 160 MHz channel width, and/or a 320 Mhz channel width.

In some demonstrative aspects, devices 102, 140 and/or 160 may be configured to implement a low-latency wireless communication mechanism, which may be configured to provide a technical solution to support low-latency transmissions, e.g., very-low latency or ultra-low latency transmissions, in a wireless communication network, for example, a Wi-Fi network, e.g., as described below.


In some demonstrative aspects, the low-latency wireless communication mechanism may be configured to provide a technical solution to support emerging time-sensitive wireless communications, e.g., as described below.


In some demonstrative aspects, devices 102, 140 and/or 160 may be configured to implement a low-latency wireless communication mechanism, which may be configured to provide a technical solution to support an efficient way to deliver a packet with very high reliability and/or with low latency, e.g., as described below.


In some demonstrative aspects, devices 102, 140 and/or 160 may include an Ultra-Low-Latency (ULL) STA, which may be configured to communicate low-latency transmissions, e.g., as described below.


In one example, the ULL STA may be configured to support enhanced reliability and/or reduced latency, for example, to support wireless-based applications, such as Augmented Reality (AR) application, Virtual Reality (VR) applications, and/or any other applications, which may require ultra-low latency and/or very high reliability.


In some demonstrative aspects, there may be a need to provide a technical solution to support wireless communication of packets with a high level of reliability and/or a low latency.


For example, an increasing number of more wireless-based applications may require high reliability and/or low latency. However, some wireless communication technologies, e.g., Wi-Fi technologies, may be configured to operate in an unlicensed spectrum and/or in an unmanaged network environment, where interference from adjacent networks may cause packet losses.


For example, in order to avoid such interference, some wireless communication technologies, e.g., in accordance with IEEE 802.11 Specifications, may require that a wireless device utilize a Clear Channel Assessment (CCA) mechanism to assess whether a wireless medium is idle prior to a transmission, and may allow the wireless device to transmit a packet when the wireless medium is determined to be idle. For example, the CCA mechanism may require the transmitter device to wait for a period of Distributed Coordination Function (DCF) Inter-frame Space (DISF) followed by a random backoff, e.g., prior to performing a data transmission. Accordingly, the CCA mechanism may add latency, e.g., a latency of abut ˜100 microseconds (usec), to the packet delivery.


For example, in many use cases and/or scenarios, a transmitter may assess that the wireless medium is idle and transmit a data packet to an intended receiver, for example, although the wireless medium may actually be busy at the receiver side, e.g., due to a hidden node problem. This scenario may result in a packet drop at the receiver.


For example, the hidden node problem may be addressed by using a virtual carrier sensing mechanism, which may implement an exchange of Request to Send (RTS) and Clear to Send (CTS) frames, prior to a data transmission. For example, a data frame may be transmitted when the RTS/CTS exchange is successful. However, this virtual carrier sensing mechanism may add additional latency to the data delivery.


In some demonstrative aspects, vices 102, 140 and/or 160 may be configured to communicate wireless transmissions according to a wireless communication technique, which may be configured to provide a technical solution to successfully deliver k packets, e.g., equal-sized data packets, to a receiver over a Wi-Fi link, e.g., while using a reduced amount, e.g., a minimal amount, of radio resources, e.g., as described below.


In some demonstrative aspects, devices 102, 140 and/or 160 may be configured to communicate wireless transmissions based on a Network Coding (NC) scheme, e.g., as described below.


In some demonstrative aspects, the NC scheme may include a linear packet-level coding scheme, e.g., as described below. In other aspects, any other NC scheme may be implemented.


In some demonstrative aspects, the NC scheme may be based on linear packet erasure codes.


In some demonstrative aspects, the NC scheme may be based on forward error correction codes.


In other aspects, the NC scheme may be based on any other type of codes, which may be configured for network coding.


In some demonstrative aspects, devices 102, 140 and/or 160 may be configured to communicate wireless transmissions based on the NC scheme, for example, to provide a technical solution to support low-latency and/or high-reliability data traffic, e.g., as described below.


In some demonstrative aspects, the NC scheme may be configured to combine, e.g., to linearly combine, data packets, for example, to form new encoded packets having dependence among them, e.g., as described below.


In some demonstrative aspects, wireless transmissions according to the NC scheme may be implemented provide a technical solution to support recovery of the original data packets, for example, even in case only some of the encoded packets are successfully received. For example, as long as a sufficient number of encoded packets, e.g., regardless of which ones, are correctly received at the receiver, the original data packets may be recovered, for example, despite possible losses of all other encoded packets.


In some demonstrative aspects, wireless transmissions according to the NC scheme may be implemented to provide a technical solution to proactively add redundancy to the traffic and/or to significantly reduce latency, e.g., compared to repetition schemes.


In some demonstrative aspects, wireless transmissions according to the NC scheme may be implemented to provide a technical solution, which is much more spectrally efficient, e.g., compared to packet repetition techniques, for example, while not requiring too much additional computational complexity for encoding and decoding.


In some demonstrative aspects, devices 102, 140 and/or 160 may be configured to communicate wireless transmissions based on the NC scheme, which may be configured to encode a plurality of data packets, e.g., including k data packets, into a plurality of encoded packets, e.g., including n>k encoded packets, e.g., as described below.


Reference is made to FIG. 3, which schematically illustrates an NC scheme 300, in accordance with some demonstrative aspects. For example, devices 102, 140 and/or 160 may be configured to communicate wireless transmissions based on the NC scheme 300.


For example, the NC scheme 300 may be based on a linear packet-level coding, e.g., as described below.


For example, as shown in FIG. 3, a set of n coded packets 304, denoted [R1, R2, . . . , Rn], may be determined by encoding a set of k packets 302, e.g., k same-sized packets, denoted [P1, P2, . . . , Pk], which may be viewed as column vectors over a finite field, e.g., a Galois Field custom-character.


For example, a linearly coded packet may be constructed as R=Σi=1kci. Pi, for example, based on an encoding vector [c1, c2 . . . , ck]T, which may include coefficients chosen from the Field custom-character.


For example, the set of n coded packets 304 may be determined, e.g., as follows:






R
ji=1kcijPi,cijcustom-character





[R1,R2, . . . ,Rn]=[P1,P2, . . . ,Pk][cij]k×n


For example, as shown in FIG. 3, the set of n coded packets 304 may be transmitted through a lossy channel/network 306, where packets may be dropped (erasure). For example, packet lose may correspond to deletion of columns of [cij].


For example, as shown in FIG. 3, the NC scheme 300 may be configured to generate the set of n coded packets 304, for example, such that a receiver may still be able to recover the original packets [P1, P2, . . . , Pk], for example, even if the receiver receives only k received encoded packets 308, denoted [R1, R2, . . . , Rk], of the n network coded packets that are linearly independent. For example, the receiver may recover the original packets [P1, P2, . . . , Pk] by determining [R1 R2 . . . Rk]M−1, wherein:

wherein the i-th column of the matrix M may include the encoding vector for Ri.


For example, the NC scheme 300 may be implemented to provide a technical solution to support an improved rate-reliability trade-off, e.g., compared to repetition techniques. For example, the improvement of the rate-reliability trade-off may increase with an increase in the coding group size (k).


For example, coding coefficients of the NC scheme 300, e.g., the coefficients ck may be chosen, for example, from codes with good performances, e.g., with a Maximum Distance Separable (MDS) property, for example, such that any choices of k encoding vectors may be linearly independent. In other aspects, any other coefficients may be implemented according to any other performance properties.


Referring back to FIG. 1, in some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to encode a plurality of data packets, for example, a stream of data packets, e.g., including k data packets, into a plurality of encoded packets, for example, a stream of encoded packets, e.g., including n encoded packets, according to an NC scheme, e.g., as described below.


In some demonstrative aspects, the count k of packets in the plurality of data packets may be equal to or greater than two, and the count n of encoded packets in the plurality of encoded packets may be greater than k, e.g., as described below.


In some demonstrative aspects, the NC scheme may be configured, for example, such that the k data packets may be decodable from a group of encoded packets including at least k encoded packets of the n encoded packets.


In some demonstrative aspects, the NC scheme may be configured, for example, such that the k data packets may be decodable from any group of p encoded packets from the n encoded packets, wherein p is a predefined value equal to or greater than k.


In some demonstrative aspects, the NC scheme may be configured, for example, such that the k data packets may be decodable from any group of k encoded packets from the n encoded packets.


In some demonstrative aspects, the k data packets may include time-sensitive data packets, e.g., as described below.


In other aspects, the k data packets may include any other additional or alternative type of packets.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to transmit the n encoded packets over a plurality of wireless communication resources, e.g., as described below.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to transmit the n encoded packets over the plurality of wireless communication resources, for example, by transmitting at least one first encoded packet over a first wireless communication resource, and transmitting at least one second encoded packet over a second wireless communication resource, e.g., as described below.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct radio 114 to transmit the n encoded packets over the plurality of wireless communication resources.

In some demonstrative aspects, the plurality of wireless communication resources may include a plurality of wireless communication links between the wireless communication device 102 and a receiver device, for example, device 140 and/or device 160, e.g., as described below.


In other aspects, the plurality of wireless communication resources may include any other additional or alternative resources.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to avoid fully performing a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) procedure prior to transmitting the n encoded packets over the plurality of wireless communication resources, e.g., as described below.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to mandate the wireless communication device to fully perform the CSMA/CA procedure prior to transmitting one or more other data packets, which are not encoded according to the NC scheme, over one or more of the wireless communication resources.


In some demonstrative aspects, the k data packets, which are encoded according to the NC scheme, may have a first latency requirement, e.g., a relatively low latency requirement. Accordingly, controller 124 may cause device 102 to avoid fully performing the CSMA/CA procedure prior to transmitting the n encoded packets, e.g., in order to support communication of the n encoded packets with relatively low latency.


In some demonstrative aspects, the other data packets, e.g., packets for which the CSMA/CA procedure is mandated, may have a second latency requirement, e.g., a non-urgent latency requirement.


For example, the first latency requirement may be lower than the second latency requirement.


In some demonstrative aspects, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to select whether to communicate data packets according to the NC scheme, for example, based on a latency requirement for communication of the data packets.


For example, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to select to communicate the data packets according to the NC scheme, for example, when the data packets include packets, e.g., urgent packets, which are to be communicated with low latency.


For example, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to avoid fully performing the CSMA/CA procedure prior to transmitting the data packets according to the NC scheme, e.g., in order to avoid a latency incurred by the CSMA/CA mechanism.


For example, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to select to communicate the data packets according to a scheme other than the NC scheme, e.g., a repetition-based scheme, for example, when the data packets include packets, e.g., non-urgent packets, which do not have a low latency requirement.


For example, controller 124 may be configured to control, trigger, cause, and/or instruct device 102 to fully perform the CSMA/CA procedure prior to transmitting the data packets, for example, when the data packets include packets, e.g., non-urgent packets, which do not have a low latency requirement.
