[0047] The embodiments of the present disclosure provide a communication method, a station device, an access point device, and a communication system.
[0048] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a station device STA, the method including:
[0049] Determine a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies that the STA requests to wake up a first access point device AP in a power saving state to transmit uplink data;
[0050] Send the first wireless frame to the second AP.
[0051] In the above embodiment, the site device carries the first identification information in the first radio frame, and the first identification information indicates that the site device requests to wake up the first access point device in the power saving state to transmit uplink data, thereby increasing the data transmission rate and reducing the transmission delay.
[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information includes: a TID corresponding to the first AP;
[0053] The TID is the TID of the rTWT information element corresponding to the STA or a newly defined TID; the newly defined TID identifies that the service transmitted by the STA is a low-latency service.
[0054] In the above embodiment, the first identification information carries a TID, which is used to identify the service to which the uplink data transmitted by the site device 101 belongs. Optionally, the TID may be the TID of the rTWT information element corresponding to the site device 101, or a newly defined TID.
[0055] Specifically, if the site device 101 is a member of a certain rTWT schedule, the TID can be the TID of the rTWT information element of the rTWT schedule. Alternatively, a new TID is defined in the UHR, and the newly defined TID is used to identify the uplink data frame transmitted by the site device 101 as a low-latency service data frame. The TID uniquely identifies the service transmitted by the STA as a low-latency service.
[0056] In combination with some embodiments of the first aspect, in some embodiments, the first identification information includes: the size of the data frame of the uplink data cached by the STA.
[0057] In the above embodiment, the first identification information carries the amount of data cached by the identification site device 101, so that the second access point device 102 knows that the site device 101 needs to wake up other access point devices to receive the uplink data to ensure the transmission delay of the low-latency service.
[0058] In combination with some embodiments of the first aspect, in some embodiments, the first identification information is carried in the QoS control field or the BSR field of the first radio frame.
[0059] In the above embodiment, for example, if the first radio frame is a QoS data frame, the first identification information is carried in the QoS control field of the first radio frame; or, if the first radio frame is a newly defined radio frame (for example, called a wake-up frame), the BSR field can be carried in the wake-up frame, and the first identification information is carried in the BSR field to request to wake up the first access point device 103 in the power saving state to transmit uplink data.
[0060] In combination with some embodiments of the first aspect, in some embodiments, the QoS control field of the first radio frame includes a QoS feature information element, and the QoS feature information element identifies the delay requirement parameters of the service transmitted by the STA.
[0061] In the above embodiment, while identifying the characteristics and QoS expectations of a traffic flow (The QoS Characteristics element contains a set of parameters that define the characteristics and QoS expectations of a traffic flow), the delay requirement parameters of the service transmitted by the STA are identified through the QoS Characteristics information element.
[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information includes: TID bitmap information;
[0063] The TID bitmap information is set to a first parameter value, indicating that the STA requests to wake up the AP of the link mapped by the corresponding TID.
[0064] In the above embodiment, the TID bitmap information indicates whether the STA requests to wake up the AP of the link mapped to the TID. For example, if the first parameter value is 1, the station device 101 requests to wake up the AP of the link mapped to the corresponding TID; alternatively, if the TID bitmap information is set to 0, the station device 101 does not request to wake up the AP of the link mapped to the corresponding TID.
[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information includes: link bitmap information;
[0066] The link bitmap information is set to a second parameter value, indicating that the STA requests the AP of the link; the AP of the link is an attached AP of the second AP, or is attached to the same AP MLD as the second AP.
[0067] In the above embodiment, the first access point device 103 requested by the station device 101 may be a subordinate AP of the second access point device 102. For example, if the second AP is an AP MLD, the link bitmap information may be used to request the awakening of the subordinate AP of the AP MLD. Alternatively, the first access point device 103 and the second access point device 102 may be subordinate to the same AP MLD.
[0068] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the first radio frame to the second AP, the method further includes:
[0069] receiving a second radio frame fed back by the second AP, and acquiring status code information in the second radio frame;
[0070] The target AP to be awakened is determined according to the status code information.
[0071] In the above embodiment, the second radio frame is used to respond to the first radio frame, that is, to respond to whether the first access point device 103 can wake up and receive the uplink data buffered by the station device 101 .
[0072] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target AP to be awakened according to the status code information includes:
[0073] The status code information includes a first status code, and it is determined that the awakened target AP includes the first AP;
[0074] The status code information includes a second status code, and TID bitmap information in the status code information is acquired. The target AP to be awakened is determined to include: an AP of a link mapped by a TID whose TID bitmap information is set to a second parameter value.
[0075] In the above embodiment, the first access point device 103 can serve as the target site device 104, wake up and receive the uplink data buffered by the site device 101, and the second access point device 102 includes a first status code in its reply frame, for example, the first status code is set to "success".
[0076] Alternatively, the second access point device 102 wakes up other site devices (site devices other than the first access point device 103) as the target site device 104. The other site devices wake up and receive the uplink data buffered by the site device 101. The second access point device 102 includes a second status code information in a reply frame, for example, the second status code information is set to "reject-with-suggested".
[0077] In conjunction with some embodiments of the first aspect, in some embodiments, after determining the awakened target AP according to the status code information, the method includes:
[0078] Under the link corresponding to the target AP, a polling frame and the uplink data frame buffered by the STA are sent to the AP MLD to which the target AP is attached.
[0079] In the above embodiment, the site device 101 sends a polling frame (poll frame) and an uplink data frame cached by the site device 101 to the AP MLD to which the target site device 104 is attached under the link corresponding to the target site device 104, so as to transmit uplink data, improve the data transmission rate, and reduce the transmission delay.
[0080] In combination with some embodiments of the first aspect, in some embodiments, the target AP is not in a busy state.
[0081] In the above embodiment, when the site device 101 sends a poll frame (poll frame), it can select the target site device 104 whose working link is not in a busy state to send it, so as to avoid the situation where the working link of the target site device 104 is in a busy state, resulting in the inability to receive the uplink data frame cached by the site device 101.

Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0147] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0148] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an independent basic service set (IBSS). Another more common scenario is that in a BSS network, there is only one central station with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.
[0149] FIG2 is a schematic diagram of a communication method and an interaction diagram of the communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:
[0150] In step 201, the station device 101 determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies that the STA requests to wake up a first access point device AP in a power saving state to transmit uplink data.
[0151] In UHR, power saving (PS) is a research priority, but AP power saving is still under development. Typically, APs come in three forms: soft APs (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile APs (or NSTR mobileAP MLD), and regular APs (or regular AP MLD). Regular APs, such as routers, support both simultaneous transmitting and receiving (STR) and NSTR communications. For example, soft APs and NSTR mobile APs are typically battery-powered, resulting in high power consumption. Furthermore, their communication with STAs is typically not continuous for extended periods. Therefore, a mechanism to support AP power saving is required.
[0152] In UHR, APs may still support multi-link communication, and STAs may also be attached to non-AP MLDs that also support multi-link communication. Multi-link communication between the two will also be established according to the existing 802.11be architecture. Because the AP or AP MLD may enter power-saving mode on each link, and the AP will wake up at regular intervals for uplink and downlink transmission on each link, reducing latency is also a research focus in UHR. If the AP enters a dormant state for a longer period, the service transmission delay will also increase, which may not meet low-latency requirements. Mechanisms are needed to ensure that STAs can transmit uplink low-latency services in a timely manner even when the AP is dormant.
[0153] In the disclosed embodiment, the station device 101 determines a first radio frame and carries first identification information in the first radio frame. The first identification information indicates that the STA requests to wake up the first access point device 103 in a power-saving state to transmit uplink data. The first radio frame can be a newly defined radio frame (e.g., a wake-up frame) or a quality of service (QoS) data frame.
[0154] The station device 101 carries first identification information in the first radio frame, and the first identification information indicates that the station device 101 requests to wake up the first access point device 103 in the power saving state to transmit uplink data. For example, when the station device 101 locally buffers uplink data to be sent, the station device 101 requests to wake up more access point devices to receive the uplink data to reduce transmission latency.
[0155] Step 202: The site device 101 sends the first wireless frame to the second AP.
[0156] Second access point device (second AP) 102 is an AP that maintains a communication connection with station device 101 and is currently awake. Station device 101 sends a first radio frame to second access point device 102, requesting that second access point device 102 wake up other APs (e.g., first access point device 103) to transmit uplink data, thereby increasing data transmission rate and reducing transmission latency.
[0157] In some embodiments, the first identification information includes: a traffic identifier (TID) corresponding to the first AP;
[0158] The TID is the TID of the restricted target wake time (rTWT) information element corresponding to the STA or a newly defined TID; the newly defined TID identifies the service transmitted by the STA as a low-latency service. For example, for backward compatibility, TID = 2, and the newly defined field is 3. In addition, it is understood that the newly defined TID can also identify the service transmitted by the STA as a non-low-latency service.
[0159] The first identification information carries a TID, which is used to identify the service to which the uplink data transmitted by the site device 101 belongs. Optionally, the TID may be the TID of the rTWT information element corresponding to the site device 101, or a newly defined TID.
[0160] Specifically, if the site device 101 is a member of a certain rTWT schedule, the TID can be the TID of the rTWT information element of the rTWT schedule. Alternatively, a new TID is defined in the UHR, and the newly defined TID is used to identify the uplink data frame transmitted by the site device 101 as a low-latency service data frame. The TID uniquely identifies the service transmitted by the STA as a low-latency service.
[0161] In some embodiments, the first identification information includes: the size of the data frame of the uplink data cached by the STA.
[0162] The size of the data frames cached by the site device 101, such as the queue size of the cached data, identifies the amount of cached data. The first identification information includes the amount of data cached by the site device 101, so that the second access point device 102 understands that the site device 101 needs to wake up other access point devices to receive the uplink data, thereby ensuring the transmission latency of low-latency services.
[0163] In some embodiments, the first identification information is carried in a QoS control field or a buffer status report (BSR) field of the first radio frame.
[0164] For example, if the first radio frame is a QoS data frame, the first identification information is carried in the QoS control field of the first radio frame; or, if the first radio frame is a newly defined radio frame (for example, called a wake-up frame), the BSR field can be carried in the wake-up frame, and the first identification information is carried in the BSR field to request to wake up the first access point device 103 in the power saving state to transmit uplink data.
[0165] In some embodiments, the QoS control field of the first radio frame includes a QoS characteristic information element (QoS characteristic element), and the QoS characteristic information element identifies a delay requirement parameter of a service transmitted by the site device 101.
[0166] The delay requirement parameter may be a specific time value, or may be mapped to a specific time value through a mapping relationship. For example, a time value of "0" may be mapped to 1 millisecond, and a time value of "1" may be mapped to 2 milliseconds.
[0167] While identifying the characteristics and QoS expectations of a traffic flow (The QoS Characteristics element contains a set of parameters that define the characteristics and QoS expectations of a traffic flow), the QoS characteristics information element is used to identify the delay requirement parameters of the service transmitted by the STA.
[0168] In some embodiments, the first identification information includes: TID bitmap information;
[0169] The TID bitmap information is set to a first parameter value, indicating that the STA requests to wake up the AP of the link mapped by the corresponding TID.
[0170] The first identification information may include multiple TIDs; therefore, the TID bitmap information indicates whether the STA requests to wake up the AP of the link mapped to the TID. For example, if the first parameter value is 1, the station device 101 requests to wake up the AP of the link mapped to the corresponding TID; alternatively, if the TID bitmap information is set to 0, the station device 101 does not request to wake up the AP of the link mapped to the corresponding TID.
[0171] In some embodiments, the first identification information includes: link bitmap information;
[0172] The link bitmap information is set to the second parameter value, indicating that the site device 101 requests the AP of the link; the AP of the link is an attached AP of the second AP, or is attached to the same AP MLD as the second AP.
[0173] The first access point device 103 requested by the station device 101 may be a subordinate AP of the second access point device 102. For example, if the second AP is an AP MLD, the link bitmap information may be used to request the awakening of the subordinate AP of the AP MLD. Alternatively, the first access point device 103 and the second access point device 102 may be subordinate to the same AP MLD.
[0174] For example, if the second parameter value is 1, the site device 101 requests to wake up the AP working on the link; or if the link bitmap information is set to 0, the site device 101 does not request to wake up the AP of the link mapped by the corresponding TID.
[0175] Step 203: The second access point device 102 wakes up the first access point device 103 (or the target access point device 104).
[0176] The second access point device 102 wakes up other APs (eg, the first access point device 103 or the target access point device 104 ) to transmit uplink data, thereby increasing the data transmission rate and reducing the transmission delay.
[0177] It is understood that in some embodiments, the target access point device 104 may be within the range of the first access point device 103 .
[0178] In step 204 , the second access point device 102 sends a second radio frame to the site device 101 . The second radio frame carries status code information, where the status code information identifies the target AP to be awakened.
[0179] The second access point device 102 feeds back a second radio frame to the site device 101. The second radio frame is used to respond to the first radio frame, that is, to respond to whether the first access point device 103 can wake up and receive the uplink data buffered by the site device 101. For example, the first access point device can serve as the target site device 104, wake up and receive the uplink data buffered by the site device 101, and the response frame of the second access point device 102 includes status code information set to "success". Alternatively, the second access point device 102 wakes up another site device (other than the first access point device 103) as the target site device 104. If the other site device wakes up and receives the uplink data buffered by the site device 101, the response frame of the second access point device 102 includes status code information set to "reject-with-suggested".
[0180] Step 205: The site device 101 receives the second radio frame fed back by the second AP, obtains status code information in the second radio frame, and determines the target AP to be awakened according to the status code information.
[0181] The site device 101 receives the second radio frame and obtains the status code information in the second radio frame; determines the awakened target AP according to the status code information to transmit the cached uplink data,
[0182] In some embodiments, determining the target AP to be awakened according to the status code information includes:
[0183] The status code information includes a first status code, and it is determined that the awakened target AP includes the first AP;
[0184] The status code information includes a second status code, and TID bitmap information in the status code information is acquired. The target AP to be awakened is determined to include: an AP of a link mapped by a TID whose TID bitmap information is set to a second parameter value.
[0185] The first access point device 103 may serve as the target site device 104, wake up and receive the uplink data buffered by the site device 101, and the second access point device 102 includes a first status code in its reply frame, for example, the first status code is set to "success".
[0186] Alternatively, the second access point device 102 wakes up other site devices (site devices other than the first access point device 103) as the target site device 104. The other site devices wake up and receive the uplink data buffered by the site device 101. The second access point device 102 includes a second status code information in a reply frame, for example, the second status code information is set to "reject-with-suggested".
[0187] Step 206 : The site device 101 sends a polling frame and the uplink data frame buffered by the STA to the AP MLD to which the target AP is attached, under the link corresponding to the target AP.
[0188] The site device 101 sends a polling frame (poll frame) and an uplink data frame cached by the site device 101 to the APMLD attached to the target site device 104 under the link corresponding to the target site device 104 to transmit uplink data, thereby increasing the data transmission rate and reducing the transmission delay.
[0189] In some embodiments, the target AP is not busy.
[0190] For example, when site device 101 sends a poll frame, it may select target site device 104 whose working link is not busy to send the poll frame, thereby avoiding the situation where the working link of target site device 104 is busy and the uplink data frame cached by site device 101 cannot be received.
