- the 802.11be working group discusses some technical solutions for low latency, including enhanced enhanced distributed channel access (EDCA) mechanism, resource preemption, multi-channel operation, transmission opportunity (TXOP) sharing , TXOP rule modification, Orthogonal Frequency Division Multiple Access (OFDMA) enhancement, resource reservation, Target Wake Time (TWT) mechanism enhancement, Multi-Link Operation (MLO) )Wait.
- EDCA enhanced enhanced distributed channel access
- TXOP transmission opportunity
- OFDMA Orthogonal Frequency Division Multiple Access
- TWT Target Wake Time
- MLO Multi-Link Operation
- the idea of the enhanced EDCA mechanism is to add a new EDCA queue for the delay-sensitive traffic and assign a higher priority EDCA competition parameter to it, thereby reducing the access delay of the delay-sensitive traffic.
- MLD Multi-Link Device
- TWT mechanism enhancement is to reuse the TWT mechanism to allocate periodic and protected low-latency target wake-up time service periods (Low Latency Target Wake Time Service Period, LL TWT SP) for latency-sensitive traffic. During this period, the link where the delay-sensitive traffic resides exclusively uses the channel or competes for the channel with high priority, thereby reducing its channel access delay.
- periodic and protected low-latency target wake-up time service periods Low Latency Target Wake Time Service Period, LL TWT SP
- This application uses the above-mentioned enhanced TWT mechanism in combination with the MLO scheme: the scheme combining the TWT element (TWT element) and the quiet element (Quiet element) is further extended to multi-link, and the transmission interference existing in the NSTR MLD is solved. To a certain extent, the delay performance of delay-sensitive traffic is improved.
- the main idea of the resource reservation scheme is to allocate periodic reserved resources for periodic delay-sensitive traffic, as shown in Figure 3. Within this reserved resource, STAs with negotiated uplink low-latency traffic are allowed to access the channel, and other STAs cannot perform uplink transmission or channel access within the reserved resources (or with low priority). channel contention).
- resource reservation scheme By reserving resources for specific traffic types, a less congested channel can be provided for delay-sensitive traffic, thereby reducing channel competition pressure. Also, other traffic can be allowed to compete for channels with lower priority, thereby improving resource utilization.
- Delay-sensitive traffic is generally bursty and periodic, and the TWT mechanism in the 802.11ax standard can just establish a periodic Target Wake Time Service Period (TWT SP) protocol between the STA and the AP. . Therefore, the TWT mechanism can be reused to allocate periodic TWT SPs to STAs with periodic uplink delay-sensitive traffic, as the realization of the above resource reservation.
- TWT SP Target Wake Time Service Period
- the TWT mechanism has certain defects: that is, before the start of the TWT SP negotiated by the STA and the AP, if the previous transmission is not completed, it will not stop its transmission, resulting in the uncertainty of the start time of the TWT SP.
- the restricted (Restricted) TWT mechanism requires that the transmission of other STAs must be stopped before the start of the Restricted TWT SP, so as to ensure the normal opening of the Restricted TWT SP and ensure that the LL Traffic can complete the transmission within the limited delay.
- TXOP transmission opportunity of other regular (Regular) STAs
- TXOP transmission opportunity of other regular (Regular) STAs
- the request to send (Request To Send, RTS) or allow to send (Clear To Send, CTS) protocol is equivalent to the handshake protocol, which is used to solve the frame exchange conflict problem caused by the hidden terminal.
- RTS is enabled after a Distributed Inter-frame Spacing (DIFS), when RTS/CTS is enabled, a station sends an RTS frame before sending a data frame, and when the receiver is willing to receive a data frame, it Will respond with a CTS frame.
- DIFS Distributed Inter-frame Spacing
- a station sends an RTS frame before sending a data frame, and when the receiver is willing to receive a data frame, it Will respond with a CTS frame.
- a time window (identified in the CTS frame) is opened for the sending station to send data frames to the station that acknowledges receipt.
- the receiver sends back an Acknowledgement (ACK) or Block Acknowledgment (BA) to the sender to confirm receipt of the data frame after a short interframe space (S
- the transmission of other STAs can be terminated before the start of the Restricted TWT SP by combining the TWT element and the Quiet element.
- the details are as follows: Set the period, start time, end time and other parameters of the TWT SP negotiated by the STA and the AP to the same value as the related parameters of the Quiet element, as shown in Figure 5. Since the Quiet element element exists in the previous standard, both traditional STA and Extremely High Throughput (EHT) STA can set their own silence time according to the Quiet element; and EHT STA participating in Restricted TWT SP can ignore Quiet element, wake up normally during the Restricted TWT SP, and then exchange data with the AP.
- EHT Extremely High Throughput
- Asynchronous transmission means that each link in the multi-link operated by the MLD operates independently and does not need to be in sync; synchronous transmission means that each link must be in sync and keep synchronized; as shown in Figure 6.
- OOB out-of-band
- IDC coexistence in devices
- PPDU alignment scheme In the multi-link data transmission method, in order to avoid the OOB or IDC interference problem, there is a PPDU alignment scheme, which can be divided into two methods: the beginning of the physical layer protocol data unit (PPDU) The time alignment is aligned with the end time of the PPDU, that is, the end time (ending time) alignment. The start time alignment of the PPDU requires certain modifications to the existing access mechanism.
- PPDU physical layer protocol data unit
- the absolute value of the difference between the ending times of the PPDUs transmitted on multiple links should be less than a certain limit (for example, Short Interframe Space (SIFS)) , which prevents OOB problems. If there is no such restriction, after the fixed (solicited) PPDU sent on a certain link 1 (Link1) ends, the response PPDU will be received after the SIFS time; During data transmission, the reception of the response PPDU will be affected.
- SIFS Short Interframe Space
- NSTR Non-AP MLD if LL TWT SP1 exists on one Link1, then consideration should be given to adjusting the transmission on other links (eg Link2) during LL TWT SP1.
- AP MLD After AP MLD's affiliated AP1 on Link1 and NSTR Non-AP MLD's affiliated STA1 on Link1 negotiate a LL TWT SP, AP MLD has two options: 1. AP MLD will be on Link1 and Link2 The PPDU sent to the Non-AP MLD is aligned with the ending time; 2. In the LL TWT SP, the AP MLD cannot send frames to the Non-AP MLD on Link2. For Non-AP MLD, the attached STA2 on Link2 stops its TXOP before the LL TWT SP starts.
- the enhanced EDCA mechanism is only a part of the overall Quality of Service (QoS) framework. It is the premise to meet the requirements of delay-sensitive applications and improve the user experience. It cannot meet the requirements alone. Specifically, it needs to cooperate with other technical solutions. use. For example, use it in conjunction with MLO to form time-sensitive links.
- QoS Quality of Service
- MLO operation stays at the conceptual/ideal level in terms of latency reduction, for example, if a device can support 8 active links, and each link can support 1ms latency with 90% probability, then this multi-link A device can theoretically support 1ms latency with 99,999999% probability.
- MLO in the current standard, the specific implementation and operation of MLO in terms of low latency have not been mentioned too much; in addition, MLO still has problems such as OOB interference inside the NSTR STA device that needs to be solved, which is far from being a real delay-sensitive service. There is also a lot of detail work required to provide the service.
- the enhanced TWT mechanism is the latest development of 802.11be on low latency, combining TWT element and Quiet element to provide protected access periods for periodic latency-sensitive traffic.
- the Quiet element element can prevent non-LL TWT SP member STAs from performing channel contention during the LL TWT SP; on the other hand, the LL TWT SP member STA can ignore the Quiet element, thereby waking up and performing data transmission at the start of the LL TWT SP.
- the content discussed at present is only for a single link, and there is no discussion about applying the Quiet element element to multi-link; and there are potential problems such as NSTR MLD equipment in multi-link, so it cannot be directly applied to multi-link.
- station equipment may also be referred to as a non-access point station (Non-AP STA).
- Non-AP STA non-access point station
- the present application proposes a scheme for cooperative operation of multi-link LL TWT SPs based on NSTR MLD equipment. For scenarios where multiple links of an NSTR MLD device carry low-latency services respectively, ensure the latency requirements for low-latency service transmission on multiple links.
- the LL TWT mentioned in this application refers to the TWT established using the Restricted TWT mechanism.
- Non-AP MLD and AP MLD are used as examples for data transmission.
- Non-AP MLD is NSTR Non-AP MLD
- AP MLD is Simultaneous transmit and receive (STR) AP MLD.
- AP MLD is NSTR Non-AP MLD
- NSTR Link Pair When an LL TWT SP is established on an NSTR Link Pair, there are two situations: 1) For the same time interval, only the LL TWT SP on one link contains this interval (that is, , the LL TWT SPs on the NSTR Link Pair do not overlap); 2) The LL TWT SPs on the two links both contain this interval (that is, the LL TWT SPs on the NSTR Link Pair have overlapping areas), as shown in Figure 9 .
- FIG. 10 is a schematic flowchart of a method 200 for wireless communication according to an embodiment of the present application.
- the method 200 for wireless communication is applied to a multi-link communication system formed by a Non-AP MLD and an AP MLD, where the Non-AP MLD at least includes A first STA and a second STA, and the first STA forms a first link with the first AP in its associated AP MLD, and the second STA forms a second link with the second AP in its associated AP MLD.
- the method 200 for wireless communication may include at least part of the following contents:
- the Non-AP MLD and/or the AP MLD perform data transmission on the first link and the second link.
- the first STA establishes the first LL TWT SP on the first link according to the first information.
- the first link and the second link are a pair of NSTR Link Pairs.
- the AP MLD includes the first AP and the second AP
- the Non-AP MLD includes the first STA and the second STA
- the first link formed by the first STA and the first AP the second STA and the second STA
- Auxiliary devices in the same MLD can communicate with each other, for example, a first AP and a second AP can communicate with each other, and a first STA and a second STA can communicate with each other.
- Non-AP MLD is generally NSTR MLD
- AP MLD is generally STR MLD.
- NSTR MLD may also include other links other than the first link and the second link, which is not limited in this application.
- the purpose of establishing the LL TWT SP is to provide a protection period for the delay-sensitive traffic of the NON-AP MLD with multiple delay-sensitive service flows. For example, within the first LL TWT SP, only the first STA and the first AP can perform channel access and perform data transmission.
- the first STA and the second STA send Restricted TWT (R-TWT) request frames to the first AP and the second AP, respectively, requesting the establishment of a respective R-TWT agreement (agreement).
- R-TWT Restricted TWT

- the uplink and downlink transmissions in LL TWT SP 1 and LL TWT SP 2 are managed by the AP uniformly, and STA1 and STA2 are not allowed to EDCA mechanism for channel access. Therefore, when starting the closest scheduled transmission before the start of LL TWT SP 2, AP1 should ensure that this scheduled transmission ends before the start of LL TWT SP 2, as shown by the dashed box in Figure 20.

- the trigger only acts as a "notification" ", without the need for an Acknowledgement (ACK) reply.
- the STA can immediately use the EDCA mechanism to compete for the channel.
- link 1 when LL TWT SP 1 is turned on, since STA2 is in a sleep state, link 1 must be the Leader Link at this time. STA1 starts to compete for the channel after receiving this information, and starts to perform uplink transmission after the competition is successful. Since the uplink PPDU1 exceeds the opening time of LL TWT SP2, AP2 should not send Trigger frames to STA2 at the opening time, but should adopt rules such as rule b (rule-b), and wait until Link1 starts to send downlinks. The purpose of sending Trigger frames is to avoid OOB problems. If the Trigger frame sent by AP2 informs STA2 that Link2 is the Leader Link at this time, then STA1 should stop channel contention and data transmission, and then synchronize with STA2 after it starts uplink transmission.
