Some demonstrative embodiments may be used in conjunction with a wireless communication network communicating over a frequency band of 60 GHz. However, other embodiments may be implemented utilizing any other suitable wireless communication frequency bands, for example, an Extremely High Frequency (EHF) band (the millimeter wave (mmWave) frequency band), e.g., a frequency band within the frequency band of between 20 Ghz and 300 GHZ, a frequency band above 45 GHZ, a frequency band below 20 GHZ, e.g., a Sub 1 GHZ (S 1G) band, a 2.4 GHz band, a 5 GHZ band, a WLAN frequency band, a WPAN frequency band, a frequency band according to the WGA specification, and the like.
In some demonstrative embodiments, header field 306 may include a modulation and coding scheme (MCS) filed 307 including an MCS value, e.g., as described below.

Scrambler 7 0 Bits X1-X7 of the initial scrambler state. Initialization MCS 5 7 Index into the Modulation and Coding Scheme table Length 18 12 Number of data octets in the PSDU. Range 1-262143 Additional 1 30 Contains a copy of the parameter ADD- PPDU PPDU from the TX VECTOR. A value of 1 indicates that this PPDU is immediately followed by another PPDU with no IFS or preamble on the subsequent PPDU. A value of 0 indicates that no additional PPDU follows this PPDU. Packet Type 1 31 Corresponds to the TXVECTOR parameter PACKETTYPE. Packet Type = 0 indicates either a PPDU whose data part is followed by one or more TRN subfields (when the Beam Tracking Request field is 0 or in Control PHY), or a PPDU that contains a request for TRN subfields to be appended to a future response PPDU (when the Beam Tracking Request field is 1). Packet Type = 1 indicates a PPDU whose data part is followed by one or more TRN subfields. The field is reserved when the Training Length field is 0. Training 5 32 Corresponds to the TXVECTOR parameter Length TRN-LEN. If the Beam Tracking Request field is 0, the Training Length field indicates the length of the training field. The use of this field is defined in 21.10.2.2.3. A value of 0 indicates that no training field is present in this PPDU. If the Beam Tracking Request field is 1 and the Packet Type field is 1, the Training Length field indicates the length of the training field. If the Packet Type field is 0, the Training Length field indicates the length of the training field requested for receive training. Aggregation 1 37 Set to 1 to indicate that the PPDU in the data portion of the packet contains an A- MPDU; otherwise, set to 0. Beam 1 38 Corresponds to the TXVECTOR parameter Tracking BEAM_TRACKING_REQUEST. Request Set to 1 to indicate the need for beam tracking (9.38.7); otherwise, set to 0. The Beam Tracking Request field is reserved when the Training Length field is 0. Last RSSI 4 39 Contains a copy of the parameter LAST_RSSI from the TXVECTOR. When set to 0, this field reserved and ignored by the receiver. The value is an unsigned integer: Values of 2-14 represent power levels (−71 + value × 2) dBm.
