RFMXWLAN_ATTR_OFDM_PREAMBLE_PUNCTURING_ENABLED

Data Type: int32
Access: read/write
Functions: RFmxWLAN_SetAttributeI32
RFmxWLAN_GetAttributeI32
Description: Specifies whether the 802.11ax MU PPDU or the 802.11be MU PPDU signal is preamble punctured.

Preamble puncturing is valid only when you set the RFMXWLAN_ATTR_CHANNEL_BANDWIDTH attribute to 80M, 160M, or 320M. This attribute is used only for SEM measurement.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is RFMXWLAN_VAL_OFDM_PREAMBLE_PUNCTURING_ENABLED_FALSE.

Get Function: RFmxWLAN_GetOFDMPreamblePuncturingEnabled
Set Function: RFmxWLAN_SetOFDMPreamblePuncturingEnabled
Values:
RFMXWLAN_VAL_OFDM_PREAMBLE_PUNCTURING_ENABLED_FALSE (0) Indicates that preamble puncturing is disabled.
RFMXWLAN_VAL_OFDM_PREAMBLE_PUNCTURING_ENABLED_TRUE (1) Indicates that preamble puncturing is enabled.

RFMXWLAN_ATTR_OFDM_PREAMBLE_PUNCTURING_BITMAP

Data Type: int64
Access: read/write
Functions: RFmxWLAN_SetAttributeI64
RFmxWLAN_GetAttributeI64
Description: Specifies the punctured 20 MHz sub-channels in the 802.11ax MU PPDU or the 802.11be MU PPDU signal when preamble puncturing is enabled.

The binary representation of the signed integer is interpreted as the bitmap, where a '0' bit indicates that the corresponding sub-channel is punctured. In the binary representation, the least significant bit (LSB) maps to the 20 MHz sub-channel lower in frequency, and the most significant bit (MSB) maps to the 20 MHz sub-channel higher in frequency. For a 80+80 MHz PPDU, the LSB represents the lowest sub-channel in the lower frequency segment. The puncturing information for the 20 MHz sub-channels of a 80 MHz PPDU are encoded in the least significant four bits. The puncturing information for the 20 MHz sub-channels of a 80+80 MHz PPDU or a 160 MHz PPDU is encoded in the least significant eight bits. The puncturing information for the 20 MHz sub-channels of a 320 MHz PPDU is encoded in the least significant sixteen bits.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is 0xFFF FFFF FFFF FFFF, indicating that none of the eight 20 MHz sub-channels of a 160 MHz PPDU are punctured. The most significant 52 bits are reserved for future use.

RFMXWLAN_ATTR_OFDM_PHASE_ROTATION_COEFFICIENT_1

Data Type: int32
Access: read/write
Functions: RFmxWLAN_SetAttributeI32
RFmxWLAN_GetAttributeI32
Description: Specifies the phase rotation coefficient 1 as defined in IEEE Standard P802.11be/D1.3.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is +1.

Get Function: RFmxWLAN_GetOFDMPhaseRotationCoefficient1
Set Function: RFmxWLAN_SetOFDMPhaseRotationCoefficient1
Values:
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_1_PLUS_ONE (0) Specifies that phase rotation coefficient 1 is +1.
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_1_MINUS_ONE (1) Specifies that phase rotation coefficient 1 is -1.

RFMXWLAN_ATTR_OFDM_PHASE_ROTATION_COEFFICIENT_2

Data Type: int32
Access: read/write
Functions: RFmxWLAN_SetAttributeI32
RFmxWLAN_GetAttributeI32
Description: Specifies the phase rotation coefficient 2 as defined in IEEE Standard P802.11be/D1.3.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is -1.

Get Function: RFmxWLAN_GetOFDMPhaseRotationCoefficient2
Set Function: RFmxWLAN_SetOFDMPhaseRotationCoefficient2
Values:
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_2_PLUS_ONE (0) Specifies that phase rotation coefficient 2 is +1.
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_2_MINUS_ONE (1) Specifies that phase rotation coefficient 2 is -1.

RFMXWLAN_ATTR_OFDM_PHASE_ROTATION_COEFFICIENT_3

Data Type: int32
Access: read/write
Functions: RFmxWLAN_SetAttributeI32
RFmxWLAN_GetAttributeI32
Description: Specifies the phase rotation coefficient 3 as defined in IEEE Standard P802.11be/D1.3.

You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is -1.

Get Function: RFmxWLAN_GetOFDMPhaseRotationCoefficient3
Set Function: RFmxWLAN_SetOFDMPhaseRotationCoefficient3
Values:
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_3_PLUS_ONE (0) Specifies that phase rotation coefficient 3 is +1.
RFMXWLAN_VAL_OFDM_PHASE_ROTATION_COEFFICIENT_3_MINUS_ONE (1) Specifies that phase rotation coefficient 3 is -1.
