Editor instructions: make the following changes in the subclause 9.23.6.5.1
… the RTS the recipient mSTA has a non-zero value in at least one of its NAV timers or the recipient mSTA has not been in listening Listening mode Mode for at least aMinListeningTime.
During an SP in which it is the destination mSTA, an mSTA that receives a valid RTS with the RA equal to the recipient mSTA MAC address and the TA corresponding to the source mSTA of the SP may respond with a mmWaveDTS if at the start of the reception of the RTS the recipient mSTA has a non-zero value in at least one of its NAV timers or the recipient mSTA has not been in Listening Mode for at least aMinListeningTime. In the latter case, the value of the Duration field of the mmWaveDTS shall include the subtraction of aMinListeningTime and the elapsed time since the mSTA has been in Listening Mode, and the NAV-SA and the NAV-DA fields shall contain the mSTA address.
Editor instructions: make the following changes in the subclause 7.2.4.1Modify the Figure 15 as follows:
BSS type / CBP only / CBP source / mmWave Privacy / ReservedBits: / B0-B1 / B2 / B3 / B3B4 / B4B5-B7
Editor instructions: add new paragraph after the paragraph the ends with “…PCP through the Extended Schedule element.”
The CBP source field is valid only if the CBP only field is set to one. The CBP source field is set to one to indicate that only the PCP/AP is allowed to initiate transmissions during the CBP, and non-PCP/non-AP STAs in the BSS can only transmit in response to a transmission from the PCP/AP. The CBP source field is set to zero to indicate that any STA in the BSS can initiate transmission during the CBP, following the CBP transmission rules.
Editor instructions: In the subclause 7.3.2.95modify the text as follows:
If value of this field differs from 0, the Source AID and the Destination AID fields are is set to the broadcast AID.
The Source AID field is set to the AID of the STA that initiates channel access during the SP or CBP allocation.
Editor instructions: In the subclause 9.23 modify the text as follows:
… and that does not receive either scheduling information or a mmWave Beacon frame with the CBP Only field set to one and the CBP source field set to zero from a PCP or AP is only allowed to transmit mmWave Beacon frames.
Editor instructions: In the subclause 9.23.4 modify the text as follows:
a)During a CBP for which the STA is identified as source or destination(9.23.6.2 Contention-based period (CBP) allocation, 9.23.7Dynamic allocation of service period and 9.23.89.23.8 Dynamic truncation of service period)
…..
… that the transaction, including acknowledgements, completes before the end of the CBP or SP in which it was initiated.
When the entire DTT is allocated to CBP through the CBP only and CBP source fields set to one in the mmWaveParameters field, a non-PCP/non-AP STA shall not transmit unless in response to a frame received from the PCP/AP. In this case, the PCP/AP is the only STA allowed to initiate a transmission during the CBP.
Non-PCP/non-AP mSTAs shall be capable of processing the Poll and Grant frames and the Allocation Info field (7.3a.2 SP Allocation Info field) to operatein an SP and in a CBP. A PCP/AP shall be capable of processing the SPR frame transmitted by a non-PCP/non-AP STA and responding to a SPR frame with a Grant frame.
Editor instructions: In the subclause 9.23.6 remove the paragraph:
Non-PCP/non-AP mSTAs shall be capable of processing the Poll and Grant frames and the SP Info field (7.3a.2 SP Info field) to operate as a destination in an SP and in a CBP. A PCP/AP shall be capable of processing the SPR frame transmitted by a non-PCP/non-AP STA and responding to a SPR frame with a Grant frame.
Editor instructions: In the subclause 9.23.6.2 modify the text in the first paragraph as follows:
The PCP/AP shall set the SPType AllocationType subfield to one, the Source AID subfield to the broadcast AID or to the AID of the source of the CBP, and the Destination AID subfield to the broadcast AID in an Allocation field within an Extended Schedule element to allocate a CBP.
Editor instructions: In the subclause 9.23.7 modify the text as follows:
A STA may set the Dynamic Allocation of Service Period field in a transmitted STA Availability element to zero to indicate that it does not respond to Poll and Grantframes during the PP and the GP.
……
The PCP/AP shall not transmit Poll or Grant frames to a STA whose Dynamic allocation of service period field in the STA Availability element is set to zero.
Editor instructions: In the subclause 9.23.7.1 modify the text as follows:
- anytime during a TXOP within a scheduled CBP for which the source AID and destination AID are is set to the broadcast AID, excluding any time that has been allocated dynamically
Editor instructions: In the subclause 9.23.7.2 modify the text as follows:
- anytime during a TXOP within a scheduled CBP for which the source AID and destination AID are is set to the broadcast AID, excluding any time that has been allocated dynamically
Editor instructions: In the subclause 9.23.3 modify the text after the Note as follows:
NOTE – STAs do not transmit a response frame to the PCP/AP when they receive a request frame from the PCP/AP with the RA equal to the broadcast/multicast address (see 9.2.7 and 9.2.8).
The PCP/AP may repeat transmission of a unicastan individually addressed frame to a STA or send a frame to any other STA as soon as one PIFS after the end of its last transmission in cases where a transmission by another STA is expected by the PCP/AP and a SIFS period elapses without the receipt of the expected transmission. if the PCP/AP does not receive a PHY-RXSTART.indication within aSIFSTime + aSlotTime + aPHY-RX-START-Delay starting at the PHY-TXEND.confirm from the end of the transmission and the medium is idle.
…..
Multiple request and response frame exchanges between the PCP/AP and a STA may occur during a single AT. The PCP/AP should complete at least one acknowledged frame exchange with each associated non-PCP/non-AP STA every dot11MaxLostBeacons BIs
