In some demonstrative embodiments, the second EDMG SC PPDU decoding scheme may not be sufficient, in some use cases, scenarios, and/or implementations, for example, with respect to EDMG OFDM PPDUs, e.g., multi-user EDMG OFDM PPDUs, for example, when the spoofing error may be greater than one OFDM symbol block, e.g., but less than two OFDM symbol blocks.
In some demonstrative embodiments, devices 102 and/or 140 may be configured to implement a signaling scheme to signal to an intended station, e.g., each intended station, of a transmitted multi-user EDMG OFDM PPDU, whether the spoofing error is less than or greater than one OFDM symbol block.

In some demonstrative embodiments, the MU EDMG OFDM PPDU decoding scheme may include calculating a total duration of the data and TRN fields, for example, by using the spoofed values indicated in the L-Header, e.g., one or more values in the length, TRN length, and/or MCS fields of L-header 206 (
In one example, the error in the calculated value of the total duration of the data and TRN fields may be, for example, less than the duration of two OFDM symbol blocks.
In one example, intended EDMG STAs may calculate the total duration of the data and TRN fields, for example, using the spoofed values indicated in the L-Header, e.g., the length, the TRN length, and/or the MCS fields, of the multi-user EDMG OFDM PPDU. For example, the error in this value may be smaller than the duration of two OFDM symbol blocks.
In some demonstrative embodiments, the MU EDMG OFDM PPDU decoding scheme may include determining a duration of the data field, e.g., the total duration of the information symbols plus padding, for example, with an error of less than two OFDM symbol blocks. For example, the duration of the data field may be determined according to a duration, e.g., an exact duration, of the TRN length, for example, as may be indicated in the EDMG-Header-A of the EDMG OFDM PPDU, e.g., in accordance with an IEEE 802.11ay Specification.
In one example, the exact duration of the TRN length may be indicated in the EDMG-Header-A of the multi-user EDMG OFDM PPDU, e.g., in accordance with an IEEE 802.11ay Specification. According to this example, a STA receiving the multi-user EDMG OFDM PPDU may be able to determine the duration of the data field, e.g., information symbols plus padding, with an error of less than two OFDM symbol blocks.
For example, a STA, e.g., each STA addressed by a multi-user EDMG OFDM PPDU, may be able to identify and correct the error, for example, based on the signaling, e.g., the spoofing error length indicator field, which may indicate whether the spoofing error is smaller or greater than 1 OFDM symbol block.
In one example, the calculated data field length may be equal to 10.1 OFDM symbol blocks, and it is known that the error is smaller than one OFDM symbol block. According to this example, the STA would know that the data field includes 10 OFDM symbol blocks. However, if the error is greater than one OFDM symbol block, the STA would know that the data field includes 9 OFDM symbol blocks.
In some demonstrative embodiments, the MU EDMG OFDM PPDU decoding scheme may include calculating a duration of the data field, which does not include the padding, for example, using one or more values in the EDMG Header B, for example, by using one or more of the values indicated in the fields PSDU Length, EDMG-MCS1, and/or EDMG-MCS2 within the EDMG-Header-B of the multi-user EDMG OFDM PPDU. In other embodiments, any other fields and/or parameters may be used to determine the duration of the data field.
In some demonstrative embodiments, the MU EDMG OFDM PPDU decoding scheme may include any other alternative and/or additional operations.
In some demonstrative embodiments, the multi-user EDMG OFDM PPDU decoding procedure may enable an intended station, for example, each intended station, e.g., devices 102 and/or 104, which receives a multi-user EDMG OFDM PPDU, to estimate, e.g., correctly, a total duration of the data field, and/or the number of data and/or padded OFDM symbol blocks, e.g., as described above.
In some demonstrative embodiments, one or more operations of the multi-user EDMG OFDM PPDU decoding procedure may be implemented, for example, to allow a user to determine the length of the data field for the user, for example, even if a “number of padded SC symbols” field is not implemented or defined, e.g., in the EDMG-Header-B 216 (

Accordingly, EDMG STAs processing a multi-user EDMG OFDM PPDU may be able to determine, for example, the actual length of the data field, e.g., without the padding, for example, based on the spoofing error length indicator field, e.g., as described above.
In some demonstrative embodiments, implementing one or more of the EDMG OFDM PPDU decoding procedure may allow, for example, to encode the EDMG OFDM PPDU, for example, even by performing padding at the PHY layer only, e.g., even without requiring padding at the MAC side.
