Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a wireless communication method, apparatus, and device. Background Technology

[0002] In related technologies, during the Target Wake Time (TWT) service period (ServicePeriod, SP), it is assumed that there are stations (STAs) that meet the conditions for Prioritized Enhanced Distributed Channel Access (P-EDCA) and initiate P-EDCA contention. Within a trigger-enabled TWT SP, STAs in power-saving mode are woken up at the start of the TWT SP and wait for a trigger frame from the access point (AP). Even though the AP can compete for the channel in any access category (AC) when sending the trigger frame, P-EDCA contention is only allowed if the AP meets the requirement of exceeding the retransmission threshold. For STAs, the longer they wait for the AP to send the trigger frame, the greater the energy consumption. For Restricted Target Wake Time (R-TWT) SPs, if the AP cannot obtain a transmission opportunity (TXOP) at the start of the R-TWT SP, it cannot prioritize scheduling delay-sensitive STAs, leading to increased latency. Within a triggered-disabled TWT SP, if the service to be transmitted by the woken-up STA is a non-voice (VO) service, even if the number of retransmissions meets the retransmission threshold, if the STA cannot compete for the channel with the AC_VO parameters, it cannot initiate P-EDCA contention. Therefore, the non-VO service will be continuously suppressed by VO traffic within the TWT SP, and the woken-up STA will be unable to compete for the channel, leading to increased power consumption.

[0003] For both trigger-enabled and trigger-disabled TWT SPs, P-EDCA contention within the TWT SP will increase the power consumption of the STA. In the worst case, the entire TWT SP is occupied by multiple STAs that initiate P-EDCA, and the services of STAs that should be scheduled within the TWT SP can only wait for the arrival of the next TWT SP, which will affect latency performance. Summary of the Invention

[0041] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0042] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Furthermore, the terms "first" and "second," etc., used herein are used only to distinguish different objects and not to describe a specific order. In the embodiments of this application, "at least one item" refers to one or more items, "more than one item" refers to two or more items, and "at least two items" refers to two or more items. "At least one of the following items" or similar expressions may refer to any combination of these items. For example, at least one of a, b, or c may mean: "a," "b," "c," "a and b," "a and c," "b and c," or "a and b and c." In the embodiments of this application, "and / or" indicates that the connected objects can have three relationships; for example, "A and / or B" may mean: only A exists, only B exists, and both A and B exist simultaneously. The character " / " generally indicates an "OR" relationship between the preceding and following objects. In the embodiments of this application, the term "instruction" can be either direct or indirect. For example, A instructing B can mean that A directly instructs B, meaning B can be obtained through A; or it can mean that A indirectly instructs B, for example, A instructing C, meaning B can be obtained through C, indicating a relationship between B and C.

[0043] The technical solutions provided in this application can be applied to wireless local area network (WLAN) systems, such as WiFi protocols. These WiFi protocols may include, but are not limited to, the 802.11 series protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols.

[0044] Figure 1 This is a schematic diagram of the communication system 100 provided in an embodiment of this application. Figure 1 As shown, the communication system 100 may include an access point (AP) 110 and a station (STA) 120.

[0045] Access point 110 can support communication or sensing based on WiFi protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols.

[0046] Site 120 can support communication or sensing based on WiFi protocols, such as 802.11a, 802.11ax, 802.11ac, 802.11b, 802.11be, 802.11g, 802.11n, 802.11bn, or next-generation protocols. Site 120 can also be called a non-access point site (non-AP STA), while an access point site (AP STA) is a type of site. In other words, in a sense, access point 110 is also a type of site.

[0047] As an example, access point 110 and site 120 can be devices in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water meters and electricity meters in smart homes, and sensors in smart cities.

[0048] As another example, access point 110 can be a terminal device (such as a mobile phone) or a network device (such as a router) with a WiFi chip. Site 120 can be a mobile phone, tablet, computer with wireless transceiver capabilities, virtual reality (VR) device, augmented reality (AR) device, wireless device in industrial control, set-top box, wireless device in self-driving, vehicle communication device, wireless device in remote medical care, wireless device in smart grid, wireless device in transportation safety, wireless device in smart city or smart home, vehicle communication device, wireless communication chip / application specific integrated circuit (ASIC) / system on chip (SOC), wearable device, etc. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday clothing, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories.

[0049] It should be noted that the communication in the communication system 100 can include communication between access point 110 and station 120, communication between stations 120, and communication between access point 110 and other access points. Access point 110 acts as a bridge connecting wired and wireless networks, and its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet.

[0050] Access point 110 and site 120 can support multi-band communication, for example, communicating simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, and 60 GHz bands, or simultaneously communicating on different channels within the same (or different) bands, improving communication throughput and / or reliability between devices. In this case, both access point 110 and site 120 are referred to as multi-band devices or multi-link devices (MLDs), sometimes also called multi-link entities or multi-band entities. For example, access point 110 is an access point multi-link device (AP MLD), and site 120 is a site multi-link device (STA MLD).

[0051] For example, a device with multi-link simultaneous transmission can be called an MLD; similarly, an AP with multi-link functionality can be called an AP MLD, and a STA with multi-link functionality can be called a STA MLD.

[0052] For example, an AP MLD can contain one or more AP logical entities; a STA MLD can contain one or more STA logical entities (e.g., multiple non-AP STA logical entities). Alternatively, an MLD containing one or more AP logical entities can be called an AP MLD, and an MLD containing one or more STA logical entities can be called a STA MLD. Multiple links can be formed between the AP logical entities in an AP MLD and the STA logical entities in a STA MLD, and data communication can occur between the AP logical entities in an AP MLD and the STA logical entities in a STA MLD through the corresponding links.

[0053] It should be understood that Figure 1 These are merely examples in this application and should not be construed as limiting the scope of this application. For example, Figure 1 The example provided includes one access point and two sites, but this application is not limited to these. For example, the communication system 100 may include multiple access points or other numbers of sites. Furthermore, the communication system 100 may also include other devices, such as network controllers, gateways, and other network entities.

[0054] To facilitate understanding of the solution provided in this application, the relevant technologies are described below.

[0055] (1) Broadcast Target Wake Time (B-TWT) The original design of B-TWT was to use a broadcast mechanism to uniformly schedule multiple devices.

[0056] (2) Target Wake Time (TWT) Element field The TWT Element field in the Beacon frame or TWT Action frame carries scheduling parameters, which include: TWT SP start time, TWT Wake Duration, TWT Wake Interval, and the identifier of the Broadcast TWT (B-TWT ID).

[0057] Based on the TWT Element field, the range of key B-TWT parameters supported by the protocol can be calculated as follows: Wake-up duration = (Nominal Minimum TWT WakeDuration) * Wake Duration Unit = 255 * 1TU (unit: µs), where TU represents a time unit (e.g., equal to 1024 microseconds); Wake-up interval = TWT Wake Interval Mantissa × 2 (TWT唤醒间隔指数（TWT Wake Interval Exponent）) =65535*2 31 (Unit: us)

[0058] To facilitate understanding of the solution provided in this application, the Restricted Target Wake Time (R-TWT) technology related to this application will be explained below.

[0059] In the TWT mechanism, the AP controls the trigger field in the TWT Element, which can be divided into a trigger-enabled TWT SP (Trigger field=1) and a trigger-disabled TWT SP (Trigger field=0). The Flow Type subfield indicates the type of interaction between the TWT requesting STA or TWT scheduled STA and the TWT responding STA or TWT scheduling AP within the target wake-up time (TWT).

[0060] To facilitate understanding of the solution provided in this application, the Enhanced Distributed Channel Access (EDCA) mechanism related to this application will be explained below.

[0061] When a STA is preparing to send a Quality of Service (QoS) data packet, if it detects that the channel is idle for a duration equal to the Arbitration Interframe Spacing Number (AIFS), the STA randomly selects an integer from zero to the Contention Window (CW) to generate a backoff time (initially CW = CWmin), and begins backoff until the count reaches zero. At this point, the STA can begin sending data. If the STA detects that the channel has re-entered a busy state during the backoff process, the backoff stops and waits for the channel to be idle for the Arbitration Interframe Spacing Number (AIFSN) time slots before restarting the backoff process. When the STA attempts to transmit but the transmission fails, the STA adjusts its CW size according to the following rule: CW = min(2 QSRC *(CW+1)-1,CWmax), where the QoS STA Retry Counter (QSRC) is the number of retransmissions, and CWmax is the maximum contention window. After any successful transmission, the STA resets the CW size to CWmin. The access interval differs for different Access Category (AC) queues. AIFS[AC] = AIFSN[AC] * Slot Time + Short Interframe Space (SIFS).

[0062] Compared to the original Distributed Coordination Function (DCF) mechanism, QoS is added, namely 4 ACs, denoted as AC_BK, AC_BE, AC_VI, and AC_VO. AC_BK, AC_BE, AC_VI, and AC_VO correspond to background data stream (BK), normal data stream (BE), video (VI) data stream, and voice (VO) data stream, respectively. The higher the priority of QoS data, the more helpful its EDCA parameters will be in obtaining channel access rights.

[0063] To facilitate understanding of the solution provided in this application, the P-EDCA mechanism related to this application is explained below.

[0064] The P-EDCA mechanism is an enhancement to the EDCA mechanism, designed to significantly reduce the latency tail of voice traffic (AC_VO). Ultra High Reliability (UHR) STAs supporting P-EDCA need to have dot11PEDCAOptionActivated=true activated and the P-EDCA Support field set to 1 in the UHR Media Access Control (MAC) Capabilities Information field. When an AP enables P-EDCA, the P-EDCA Enabled field must be set to 1 in the UHR operation element.

[0065] P-EDCA operation procedure: STAs (including AP and non-AP STAs) initiate a P-EDCA competition process when all of the following conditions are met: The AP has enabled P-EDCA in the current Basic Service Set (BSS), and the STA has explicitly informed the AP that it will use P-EDCA; The STA has cached AC_VO traffic that meets a certain retransmission threshold (e.g., QSRC) and the number of P-EDCA retries initiated is less than a certain threshold (e.g., P-EDCA STA Retry Counter, PSRC)). Specifically, for example, QSRC[AC_VO]≥dot11PEDCARetryThreshold and PSRC[AC_VO]≤dot11PEDCAConsecutiveAttempt.

[0066] To initiate P-EDCA contention, a STA meeting the P-EDCA conditions should send a DeferSignal to initiate a protected short contention period. This P-EDCA contention frame is called a DeferSignal-Clear To Send (DS-CTS) frame. This DS-CTS frame should be sent as a non-high throughput (non-HT) physical layer protocol data unit (PPDU) or a non-HT PPDU duplicate, and transmitted at a data rate of 6 Mbps to OUI 00:0F:AC+. <ana>Specify the address; the parameters transmitted by this DS-CTS frame (such as duration, CWds, AIFSN) are shown in Table 1 below.

[0067] Table 1. Default P-EDCA parameter set

[0068] P-EDCA contention should begin immediately after the DS-CTS frame is sent.

[0069] Only AC_VO class traffic is allowed to participate in P-EDCA contention; other ACs (AC_VI, AC_BE, AC_BK) are temporarily prohibited from contention. Contention parameters should use those in Table 1 above (AIFSN=2, CWmin=7, CWmax=7). Figure 2 As shown, the STA that initiates a transmission opportunity (TXOP) during P-EDCA contention should send a request to send (RTS) frame as the first frame in the TXOP, followed by a Clear To Send (CTS) frame; then, the STA sends an Aggregate Medium Access Control protocol data unit (A-MPDU) (such as A-MPDU1), and then receives a Block Acknowledgment (BA) frame.

[0070] Compared to the more aggressive parameters of ordinary EDCA, P-EDCA, although setting a larger CWmin value, greatly reduces the number of competing nodes because the contention is protected and only specific AC_VO traffic is allowed to participate. This effectively reduces collisions, increases the overall probability of successful transmission, and results in lower and more stable actual latency.

[0071] If contention fails or TXOP is not initiated: DS-CTS can be retried (up to dot11PEDCAConsecutiveAttempt times); after reaching the retry limit: P-EDCA is suspended until QSRC[AC_VO] is reset, limiting continuous preemption and preventing AC_VO from monopolizing the channel.

[0072] To facilitate understanding of the solution provided in this application, the problems addressed by this application are explained below.

[0073] In TWT SP, assume that there exists an STA that satisfies the P-EDCA condition to initiate P-EDCA competition; Within a trigger-enabled TWT SP, STAs in power-saving mode are woken up at the start of the TWT SP and wait for the trigger frame sent by the AP. Even though the AP can compete for the channel with any AC when sending the trigger frame, P-EDCA contention is only allowed if the AP meets the requirement of exceeding the retransmission threshold. For STAs, the longer they wait for the AP to send the trigger frame, the greater the energy consumption. For R-TWT SPs, if the AP cannot obtain TXOP at the start of the R-TWT SP, it cannot prioritize scheduling delay-sensitive STAs, resulting in increased latency.

[0074] Within a triggered-disabled TWT SP, if the service to be transmitted by the woken-up STA is a non-VO service, even if the number of retransmissions meets the retransmission threshold, if the STA cannot compete for the channel with the AC_VO parameters, it cannot initiate P-EDCA contention. Therefore, the non-VO service will be continuously suppressed by VO traffic within the TWT SP, and the woken-up STA will be unable to compete for the channel, leading to increased energy consumption.

[0075] For both trigger-enabled and trigger-disabled TWT SPs, P-EDCA contention within the TWT SP will increase the power consumption of the STA. In the worst case, the entire TWT SP is occupied by multiple STAs that initiate P-EDCA, and the services of STAs that should be scheduled within the TWT SP can only wait for the arrival of the next TWT SP, which will affect latency performance.

[0076] For example, such as Figure 3 As shown, STA1 in Power Save mode is woken up at the start of TWT SP1, waiting for a trigger frame from the AP, but no trigger frame is received by the end of TWT SP1. The entire TWT SP1 is occupied by STAs that initiate P-EDCA, such as STA2 and STA3, which also support P-EDCA. Services on STA1 in Power Save mode can only wait for the next TWT SP, impacting latency performance. Figure 3 As shown, after a successful P-EDCA contention, a STA2 device supporting P-EDCA sends a Medium Access Control protocol data unit (MPDU) within TWT SP1. Figure 3 As shown, after a successful P-EDCA contention, STA3, which supports P-EDCA, sends an MPDU outside of TWT SP1.

[0077] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0078] Figure 4 This is a schematic flowchart of a wireless communication method 200 provided in an embodiment of this application, which can be executed by a STA. For example, Figure 4 The STA shown can be as follows: Figure 1 The station shown is 120.

[0079] like Figure 4 As shown, the wireless communication method 200 may include some or all of the following: S210, STA receives the first frame from AP; The first frame includes a first field, which indicates whether P-EDCA contention is allowed within the TWT SP, or whether the P-EDCA function is enabled within the TWT SP.

[0080] In this embodiment, the AP can set the P-EDCA function switch in the TWT SP through the first field, which can avoid the excessive occupation of TWT SP resources due to P-EDCA contention (at present, the AP cannot control the time used by P-EDCA operation, which leads to the excessive occupation of TWT SP resources by STAs that support P-EDCA). This can reduce the power consumption of energy-saving STAs in the TWT SP and reduce the latency of non-AC_VO traffic in the TWT SP, thereby improving the transmission performance in the TWT SP.

[0081] In some embodiments, the first field can be a newly added P-EDCA Enabled field. Of course, the first field can also be other fields, such as a newly added P-EDCA Activation field, or a newly added P-EDCA Enabled field; this application is not limited to these.

[0082] Optionally, the first field occupies 1 bit; where a value of 0 indicates that P-EDCA contention is not allowed within the TWT SP, or a value of 0 indicates that P-EDCA functionality is disabled within the TWT SP; a value of 1 indicates that P-EDCA contention is allowed within the TWT SP, or a value of 1 indicates that P-EDCA functionality is enabled within the TWT SP; or a value of 1 indicates that P-EDCA contention is not allowed within the TWT SP, or a value of 1 indicates that P-EDCA functionality is disabled within the TWT SP; a value of 0 indicates that P-EDCA contention is allowed within the TWT SP, or a value of 0 indicates that P-EDCA functionality is enabled within the TWT SP. It should be noted that the first field may also occupy more bits, and this application is not limited in this regard.

[0083] In some embodiments, the AP can predict the number of active P-EDCA-supporting STAs within the TWT SP and the service type transmitted by the active P-EDCA-supporting STAs within the TWT SP (such as whether the active P-EDCA-supporting STAs within the TWT SP are transmitting AC_VO services) through a specific algorithm. When a certain threshold is met (such as QSRC[AC_VO]), the AP can enable or disable the P-EDCA function within the TWT SP through the first field.

[0084] In some embodiments, the TWT SP is an R-TWT SP; or, the TWT SP is a trigger-enabled TWT SP.

[0085] In some embodiments, the first frame includes at least one of the following: Beacon frame, Probe Response frame, Association Response frame, Re-Association Response frame.

[0086] In some embodiments, if the first field indicates that P-EDCA contention is allowed within the TWT SP, or if the first field indicates that P-EDCA functionality is enabled within the TWT SP, the first frame may further include a second field and / or a third field. The second field is used to indicate the first retransmission threshold corresponding to P-EDCA; The third field is used to indicate the second retransmission threshold corresponding to P-EDCA, or the third field is used to indicate the increment of the second retransmission threshold corresponding to P-EDCA relative to the first retransmission threshold corresponding to P-EDCA. Specifically, the number of retransmissions of the first traffic of the STA that initiates P-EDCA contention outside the TWT SP needs to meet the first retransmission number threshold, and the number of retransmissions of the first traffic of the STA that initiates P-EDCA contention inside the TWT SP needs to meet the second retransmission number threshold.

[0087] It should be noted that currently, STAs supporting P-EDCA use the same retransmission threshold both inside and outside the TWT SP. P-EDCA inherently sacrifices fairness for latency performance; during the TWT SP (lasting approximately tens of milliseconds), this unfairness increases the power consumption of energy-efficient STAs and the latency of non-AC_VO traffic. In this embodiment, if the first field indicates that P-EDCA contention is allowed within the TWT SP, or if the first field indicates that P-EDCA is enabled within the TWT SP, the AP can configure a dedicated retransmission threshold (i.e., a second retransmission threshold) for STAs to initiate P-EDCA within the TWT SP. This second retransmission threshold is greater than the first retransmission threshold, which can prevent excessive occupation of TWT SP resources due to P-EDCA contention, reduce the power consumption of energy-efficient STAs within the TWT SP, and reduce the latency of non-AC_VO traffic within the TWT SP, thereby improving transmission performance within the TWT SP.

[0088] Optionally, if the first field indicates that P-EDCA contention is not allowed in the TWT SP, or if the first field indicates that P-EDCA functionality is disabled in the TWT SP, the first frame may include a second field and a third field, and set the second field and the third field to fixed values, such as 0; the first frame may also exclude the second field and the third field.

[0089] In some embodiments, the first traffic is traffic with access category AC_VO. Optionally, the first traffic is traffic sent by the STA with access category AC_VO. Of course, the first traffic can also be other traffic, and this application is not limited to this. For example, for the STA, the first traffic is AC_VO traffic; for the AP, the first traffic can be any traffic.

[0090] In some embodiments, the AP can configure a retransmission threshold (i.e., a second retransmission number threshold) for the STA specifically for initiating P-EDCA within the TWT SP, based on the TWT SP length.

[0091] In some embodiments, the second field can be a P-EDCA QSRC threshold field, and the third field can be a newly added P-EDCA QSRC field. Of course, the third field can also be other fields, such as a newly added P-EDCA QSRC threshold field or a newly added QSRC threshold field. This application does not limit this.

[0092] Optionally, the third field may occupy 2 bits, wherein the third field indicates the increment of the second retransmission threshold corresponding to P-EDCA relative to the first retransmission threshold corresponding to P-EDCA, for example, the increment may be 1-4.

[0093] In some embodiments, the first frame includes an Ultra High Reliability (UHR) operation element; wherein the P-EDCA operation parameter field in the UHR operation element includes at least one of the following: the first field, the second field, and the third field.

[0094] In some implementations, the AP declares P-EDCA parameter capabilities by carrying the UHR Operation element through a Beacon frame, Probe Response frame, Association Response frame, or Re-Association Response frame. The UHR Operation element format can be as follows: Figure 5 As shown, the P-EDCA Operation Parameters field carries P-EDCA parameters. The second field can be a P-EDCA QSRC threshold field, and at least one of the first and third fields can be located in the reserved fields (B19~B23). For example, the first field can be located in B19 of the reserved fields (B19~B23), and B20~B23 are still reserved fields. Figure 6 As shown. For example, the third field can be located in B19~B20 of the reserved fields (B19~B23), where B21~B23 are still reserved fields, as shown. Figure 7 As shown. For example, the first field could be B19 within the reserved fields (B19~B23), the third field could be B20~B21 within the reserved fields (B19~B23), and B22~B23 would also be reserved fields, as shown. Figure 8 As shown.

[0095] Among them, such as Figures 5 to 8 As shown, the UHR Operation element format may also include the following fields: The field includes: element ID, length, element ID extension, UHR operation parameters, Basic UHR-MCS and NSS Set, UHR operation information, Dynamic Power Save (DPS) operation parameters, Number of Partial Channel Angles (NPCA) operation parameters, and Dynamic Bandwidth Selection (DBE) operation parameters.

[0096] Among them, such as Figures 5 to 8 As shown, the P-EDCA Operation Parameters field may also include the following fields: P-EDCA Exponent Contention Window Minimum (ECWmin) field, P-EDCA Exponent Contention Window Maximum (ECWmax) field, P-EDCA AIFSN field, Defer-signal Contention Window (CW DS) field, P-EDCA PSRC Threshold field, P-EDCA QSRC Threshold field.

[0097] In some implementations, when the STA (which supports P-EDCA) receives the first frame, it parses the UHR Operationelement and updates the local P-EDCA parameters. These P-EDCA parameters are used to determine when the STA can initiate P-EDCA contention.

[0098] Optionally, for P-EDCA STAs that support TWT functionality (such as non-AP STAs), P-EDCA contention can only be initiated during the TWT SP period if the following conditions are met simultaneously: additional P-EDCA Enabled=1, allows P-EDCA contention to be initiated within the SP; The STA has cached AC_VO traffic; The number of retransmissions for the corresponding AC_VO stream is greater than or equal to the second retransmission threshold (which can be based on the above). Figure 5 The additional P-EDCA QSRC field in the code can be used to determine this, or it can be based on the above. Figure 5 (The additional P-EDCA QSRC field and the P-EDCA QSRC threshold field are determined). The number of times the STA initiates P-EDCA competition is less than or equal to the P-EDCA PSRC Threshold.

[0099] Optionally, during the TWT SP period, additional P-EDCA Enabled=1, and the AP can initiate P-EDCA contention when any of the following conditions are met: This TWT SP is an R-TWT SP, meaning that Broadcast TWT Recommendation field = 4, indicating that the corresponding broadcast TWT SP is an R-TWT SP; This TWT SP is a trigger-enabled TWT SP, meaning the trigger field is 1.

[0100] Optionally, during the TWT SP period, when additional P-EDCA Enabled=0, neither AP nor STA (non-APSTA) can initiate P-EDCA contention; at the start of the TWT SP period, QSRC[AC_VO] pauses counting.

[0101] In some embodiments, if the first field indicates that P-EDCA contention is allowed within the TWT SP, or if the first field indicates that P-EDCA functionality is enabled within the TWT SP, the AP is allowed to use a first retransmission threshold outside the TWT SP, and the AP is allowed to use a third retransmission threshold within the TWT SP, wherein the third retransmission threshold is less than the first retransmission threshold.

[0102] It should be noted that currently, APs must satisfy QSRC[AC_VO]≥dot11PEDCARetryThreshold to compete for the channel. This causes APs to be unable to schedule non-AP STAs in a timely manner at the start of TWT SP, resulting in increased latency. In this embodiment, for STAs in the network that support P-EDCA but do not support TWT (non-AP STAs), APs are allowed to use the first retransmission threshold outside of TWT SP, and the third retransmission threshold inside TWT SP. In this scenario, the access efficiency of APs is improved.

[0103] The above text combined Figures 4 to 8 The STA-side embodiments of this application are described in detail below, in conjunction with... Figure 9 The AP-side embodiments of this application are described in detail. It should be understood that the AP-side embodiments correspond to the STA-side embodiments, and similar descriptions can be found in the STA-side embodiments.

[0104] Figure 9 This is a schematic flowchart of a wireless communication method 300 provided in an embodiment of this application. The wireless communication method 300 can be executed by an access point (AP). For example, Figure 9 The access point shown can be as follows: Figure 1 The access point shown is 110.

[0105] like Figure 9 As shown, the wireless communication method 300 may include some or all of the following: S310, AP sends the first frame to STA; The first frame includes a first field, which indicates whether P-EDCA contention is allowed within the TWT SP, or whether the P-EDCA function is enabled within the TWT SP.

[0106] In this embodiment, the AP can set the P-EDCA function switch in the TWT SP through the first field, which can avoid the excessive occupation of TWT SP resources due to P-EDCA contention (at present, the AP cannot control the time used by P-EDCA operation, which leads to the excessive occupation of TWT SP resources by STAs that support P-EDCA). This can reduce the power consumption of energy-saving STAs in the TWT SP and reduce the latency of non-AC_VO traffic in the TWT SP, thereby improving the transmission performance in the TWT SP.

[0107] In some embodiments, if the first field indicates that P-EDCA contention is allowed within the TWT SP, or if the first field indicates that P-EDCA functionality is enabled within the TWT SP, the first frame may further include a second field and / or a third field. The second field is used to indicate the first retransmission threshold corresponding to P-EDCA; The third field is used to indicate the second retransmission threshold corresponding to P-EDCA, or the third field is used to indicate the increment of the second retransmission threshold corresponding to P-EDCA relative to the first retransmission threshold corresponding to P-EDCA. Specifically, the number of retransmissions of the first traffic of the STA that initiates P-EDCA contention outside the TWT SP needs to meet the first retransmission number threshold, and the number of retransmissions of the first traffic of the STA that initiates P-EDCA contention inside the TWT SP needs to meet the second retransmission number threshold.

[0111] In some embodiments, the TWT SP is an R-TWT SP; or, The TWT SP is a trigger-enabled TWT SP.

[0112] In some embodiments, the first frame includes at least one of the following: Beacon frame, probe response frame, association response frame, reassociation response frame.
