TGad Editor: Replace lines 17-18 of page 92 as follows:
The Chan-FBCK-CAP field is set to one to indicate the STA is capable to return channel measurement during beam refinement. The Chan-FBCK-CAP field is set to zero to indicate the STA is only able to return BS-FBCK during beam refinementThe Chan-FBCK-CAP field indicates a capability to return channel measurement during beam refinement. If it is set to zero, the STA can only return BS-FBCK during beam refinement
TGad Editor: in Figure 71 shorten L-RX to 5 bits. Move the redundant bit to the reserved bit.
TGad Editor: Modify lines 1-2 in page 92 as follows:
RX field is multiplied by 4. Possible values range form 0-16, corresponding to 0-64 TRN-R fields. Other values are reserved. If the field is set to zero, the transmitting STA does not need receiver training as part of beam refinement.
TGad Editor: Modify lines 21-23 in page 189 as follows:
The TXSS ends at the end time of the ScS frame from the initiator with the CDOWN field set to zero. If the responder is unable to receive this e last frame in the initiator TXSS, the responder shall assume that the initiator TXSS has completed at the expected or actual, whichever comes first, end time of this e SS framefrom the initiator with the CDOWN field equal to zero.
TGad Editor: Remove the following text in line21-23 page 190:
A responder RXSS may be performed as part of a RSS only if the responder has indicated it uses one antenna pattern by setting the total number of sectors field to 1 in the responder‘s mmWave Capabilities element.
TGad Editor: Insert the following text after line 21 in page 197:
If the initiator has requested an MID phase by setting the MID-REQ to one, and the responder rejected the response by setting the MID-grant to zero, the initiator shall send a BRP frame with the MID-REQ set to zero and the L-RX set to indicate the number of TRN-R fields it request for use in the BRP phase.
If the responder has requested an MID phase by setting the MID-REQ to one, and the initiator has rejected the response by setting the MID-grant to zero, the initiator shall send a BRP frame with the capability request subfield set to one. The responder shall responde with a BRP frame with the MID-REQ set to zero and the L-RX set to indicate the number of TRN-R fields it request for use in the BRP phase.
TGad Editor: Modify lines 28-29 in page 215 as follows:
frame containing a mmWave Beam Refinement element with the TX-TRN-OK field and TX-train-response field both set to one and the BS-FBCK field set to indicate the TRN-T field on which it
TGad Editor: Modify lines 35-36 in page 189 as follows:
BT. During a CBP, an initiator shall not obtain a TXOP with an initiator RXSSRXSS if an ISS is required to obtain the TXOP.
TGad Editor: Modify lines 40-41 in page 215 as follows:
with TRN-T fields. The responding STA shall then respond with a beam refinement frame with the TX-train-response field set to one and the BS-FBCK and channel measurement feedback element as above.
TGad Editor: Remove line 12 of page 216:
A beam refinement frame shall not be both a TX training request packet and RX response packet.
TGad Editor: Modify lines 18-19 of page 220 as follows:
transmitted to the initiator. The number of TRN-R subfields appended to the following packet may be lower than the value of the L-RX field specified in the beam refinement frame but shall be more than one.
TGad Editor: Insert the following subclause:
21.8.2.2.3 Beam Refinement packet duration
The minimum duration of a beam refinement packet when sent in an SC PHY is 18 SC blocks (see 21.6.3.2.4) and, if needed, the packet shall be extended using zero padding to this length. The zeros shall be added before the scrambler. The length field in the packet header shall include the actual length of the packet.
The minimum duration of a beam refinement packet when sent in an OFDM PHY is 20 OFDM symbols and, if needed, the packet shall be extended using zero padding to this length. The zeros shall be added before the scrambler. The length field in the packet header shall include the actual length of the packet.
