[0124] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0125] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0126] In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0127] Specifically, the station device 101 may be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the station device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[0128] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, as well as support the next generation 802.11 protocol, but is not limited to these.

[0129] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0130] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. 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.

[0131] 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.

[0132] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association 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 dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals 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, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0133] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0134] Step 201, the site device 101 determines a first wireless frame; wherein the first wireless frame includes one or more of the following first identification information, and the first identification information identifies: whether the STA (site device 101) supports communication on the auxiliary channel within the service time SP of the individual target wake-up time individual TWT.

[0135] In UHR, a bandwidth of 320 MHz (160 MHz + 160 MHz) will be supported. Therefore, bandwidth resources need to be properly configured to improve bandwidth resource utilization. In the embodiment of the present disclosure, the site device 101 determines a first radio frame. The first radio frame can be a radio frame sent during the initial association process, such as a probe request frame, an association request frame, or a re-association request frame.

[0136] The site device 101 carries first identification information in the first wireless frame, and uses the first identification information to identify whether the STA supports communication on a secondary channel (or secondary channel) within the service time SP of the individual target wake-up time individual TWT, that is, the first identification information identifies whether the STA supports the subchannel selective transmission (SST) mechanism. Specifically, in order to make full use of channel resources, the SST mechanism can schedule site devices using 20MHz or 80MHz to the secondary channel for sending and receiving data. For example, the access point device 102 can schedule a site device to receive downlink data on a designated secondary channel within a certain optimized target wake-up time (TWT), or to send uplink data through scheduling; the device scheduled to work on the secondary channel can be called an SST site.

[0137] Among them, target wake up time (TWT) is a technology used for energy saving, which aims to further reduce the power consumption of Wi-Fi networks. Specifically, TWT technology enables STA and AP to negotiate the service period (SP) to determine the STA's sleep and wake-up time and frequency; STA remains active and communicates during the service period, so that it can sleep outside of the service period to achieve the purpose of energy saving. Among them, in the sleep state, STA is allowed to stop listening for Beacons and can negotiate with the AP to wake up at a specific time to obtain air interface resources, so that the STA is awakened only when it needs to interact with messages.

[0138] In addition, TWT technology enables the AP to provide higher-quality services to multiple STAs, minimizing contention or overlap, thereby reducing Wi-Fi network power consumption and improving spectrum efficiency. Specifically, the AP can assign different TWT SPs, significantly reducing the number of STAs interacting with each TWT SP. This reduces the number of STAs competing for channels within the TWT SP, thereby reducing the probability of conflicts, channel access latency, and service latency.

[0139] Typically, TWT modes include individual TWT and broadcast TWT. Individual TWT refers to a one-to-one TWT SP established between the AP and the STA, which can be initiated by the STA to actively initiate a TWT SP establishment request or can be triggered unilaterally by the AP. In the embodiment of the present disclosure, the site device 101 indicates through the first wireless frame that it supports auxiliary channel communication within the individual TWT SP, so that the access point device 102 can schedule the site device 101 to the auxiliary channel communication within the individual TWT SP.

[0140] Step 202: The site device 101 sends the first radio frame.

[0141] The site device 101 sends the first radio frame to the access point device 102, so that the access point device 102 determines whether to schedule the site device 101 to the auxiliary channel for data transmission and reception according to the first identification information, so as to improve bandwidth resource utilization.

[0142] Specifically, in Wi-Fi application scenarios, there is an imbalance in the communication parameters supported by APs and STAs. For example, the AP supports 160MHz bandwidth, while the STA only supports 20MHz bandwidth. In this way, if the AP and STA always communicate in a 20MHz BSS, bandwidth resources are seriously wasted. Therefore, in the embodiment of the present disclosure, the site device 101 indicates through the first radio frame that it supports communication on the auxiliary channel within the individual TWT SP, so that the access point device 102 can schedule the site device 101 to communicate on the auxiliary channel within the individual TWT SP. It can be understood that in the embodiment of the present disclosure, when the STA communicates in the auxiliary channel, the AP may allocate RU or MRU, or the STA may occupy the entire bandwidth for communication, for example; the AP allocates RU or MRU, for example, the STA associated with the AP is able to operate in at least one secondary 20MHz, 80MHz or 160MHz channel during individual TWT SP, then the AP schedules resource units (RU) or multiple resource units (MRU) for the STA in the auxiliary channel, such as 26-tone (subcarrier), MRU such as 26tone+52tone, etc., to maximize channel resource utilization.

[0143] In some embodiments, the first identification information is carried in an ultra high reliability capabilities (UHR capabilities) information element of the first radio frame.

[0144] The first wireless frame may include a UHR capabilities information element, and the UHR capabilities information element may be used to carry first identification information. For example, the first identification information may be carried in the UHR capabilities information element field, occupying one bit to carry the first identification information. If the first identification information is set to "0", it indicates that the STA does not support communication on the auxiliary channel within the individual TWT SP; if the first identification information is set to "1", it indicates that the STA supports communication on the auxiliary channel within the individual TWT SP.

[0145] In some embodiments, the UHR capabilities information element includes second identification information, where the second identification information identifies a maximum operating channel bandwidth parameter supported by the STA.

[0146] For example, the UHR capabilities information element is used to carry the second identification information, occupying 2 bits to carry the second identification information. If the second identification information is set to "00", it indicates that the STA supports a maximum channel bandwidth of 20 MHz; if the second identification information is set to "01", it indicates that the STA supports a maximum channel bandwidth of 80 MHz; if the second identification information is set to "10", it indicates that the STA supports a maximum channel bandwidth of 160 MHz.

[0147] In some embodiments, the UHR capabilities information element includes third identification information, where the third identification information identifies that the STA supports communication on one or more auxiliary channels.

[0148] For example, the UHR capabilities information element is used to carry the third identification information, and one bit is occupied to carry the third identification information. If the third identification information is set to "0", it indicates that the STA communicates under one of the auxiliary channels; if the third identification information is set to "1", it indicates that the STA supports communication under multiple auxiliary channels.

[0149] Step 203: The access point device 102 receives the first wireless frame.

[0150] The access point device 102 determines, according to the first identification information, whether to schedule the site device 101 to the auxiliary channel for data transmission and reception, so as to improve bandwidth resource utilization.

[0151] Step 204: The station device 101 determines a first target wake-up time TWT establishment frame; wherein the first TWT establishment frame includes fourth identification information, and the fourth identification information identifies the bandwidth of the auxiliary channel supported by the STA;

[0152] In which, during the TWT negotiation process, the site device 101 determines a first TWT setup frame, and includes fourth identification information in the first TWT setup frame, and identifies the bandwidth of the auxiliary channel supported by the STA through the fourth identification information.

[0153] Optionally, the bandwidth of the auxiliary channel supported by the STA may include: whether it supports communication under multiple auxiliary channels and the specific supported bandwidth value; for example, if the STA supports communication under multiple auxiliary channels and only supports 20MHz bandwidth, then during the TWT establishment process, the fourth identification information identifies that it supports multiple secondary 20MHz bandwidth operations; if the STA supports communication under multiple auxiliary channels and only supports 80MHz bandwidth, then during the TWT establishment process, the fourth identification information identifies that it supports multiple secondary80MHz bandwidth operations; or if the STA supports only 160MHz bandwidth, the fourth identification information identifies that it can communicate under another secondary 160MHz bandwidth.

[0154] Step 205: The site device 101 sends the first TWT establishment frame.

[0155] In some embodiments, the fourth identification information is carried in the control field of the first TWT establishment frame.

[0156] As shown in FIG2 , the fourth identification information may be carried in the control field of the first TWT establishment frame.

[0157] Exemplarily, the control field may include a 1-bit null data PPDU (NDP) paging indication (NDP Paging Indicator) field, a 1-bit responder power management (PM) mode (Responder PM Mode) field, a 2-bit negotiation type (Negotiation Type) field, a 1-bit TWT information frame disabled (TWT Information Frame Disabled) field, a 1-bit wake-up duration unit (Wake Duration Unit) field, a 1-bit link bitmap present field and a 2-bit reserved (reserved) field.

[0158] Optionally, the fourth identification information may be carried in the reserved field. For example, 2 bits are occupied to carry the fourth identification information, and the fourth identification information is set to "00", indicating that it supports multiple secondary 20MHz bandwidth operations; the fourth identification information is set to "01", indicating that it supports multiple secondary 80MHz bandwidth operations; or the fourth identification information is set to "10", indicating that it can communicate in another secondary 160MHz bandwidth.

[0159] In some embodiments, the first TWT establishment frame further includes:

[0160] Fifth identification information, where the fifth identification information identifies the auxiliary channel selectable by the STA.

[0161] Among them, the auxiliary channel that the STA can select is identified by the fifth identification information; for example, the STA only supports a maximum bandwidth of 20MHz and supports communication under multiple secondary channels, and the AP supports a maximum of 320MHz, then the STA can select 15 auxiliary channels; the fifth identification information can be used to identify RU or MRU allocation, then the bandwidth (BW) identification, RU index and MRU index can adopt the identification method in the existing standard, which will not be repeated here.

[0162] In some embodiments, the fifth identification information is carried in an individual TWT parameter set field of a TWT parameter information TTWT Parameter Information field of the first TWT establishment frame;

[0163] The fifth identification information includes the target wake-up time channel TWT channel subfield and the newly added subfield in the individual TWT parameter set field.

[0164] Exemplarily, the individual TWT parameter set field is shown in FIG2 , which may include a 2-byte request type field, a 0 or 8-byte target wake time field, a 0 or 3, 9-byte TWT group assignment field, a 1-byte scalar minimum TWT wake time field, a 2-byte TWT wake interval mantissa field, a 1-byte TWT channel field, a 0 or 4-byte NDP paging field, and a newly added subfield. The newly added subfield may occupy one byte.

[0165] The fifth identification information is jointly indicated by the TWT channel subfield and the newly added subfield. For example, if the STA supports communication under multiple secondary channels and the AP supports a maximum of 320MHz, if the STA only supports a maximum of 20MHz bandwidth, the STA can select 15 auxiliary channels; if the STA only supports a maximum of 80MHz bandwidth, the STA can select 3 auxiliary channels; if the STA only supports a maximum of 160MHz bandwidth, the STA can select 1 auxiliary channel; the fifth identification information may include a bandwidth (BW) identifier, an RU index, and an MRU index, which can be jointly indicated by a byte of the TWT channel subfield and a byte of the newly added subfield, and can indicate each auxiliary channel separately.

[0166] In some embodiments, the control field of the first TWT establishment frame includes sixth identification information, and the sixth identification information identifies whether the newly added subfield exists in the individual TWT parameter set field.

[0167] Among them, the control field is used to carry TWT control information, and a bit in the control field can be used to identify whether the newly added subfield exists in the individual TWT parameter set field.

[0168] Step 206: The access point device 102 receives a first TWT establishment frame.

[0169] The access point device 102 receives the first TWT establishment frame and establishes a TWT with the site device 101 according to the first TWT establishment frame.

[0170] In some embodiments, the method comprises:

[0171] Step 207: Receive a second wireless frame; wherein the second wireless frame includes seventh identification information, and the seventh identification information identifies that the access point device AP supports communication on an auxiliary channel within the individual TWT SP.

[0172] The access point device 102 carries seventh identification information in the second wireless frame, and the seventh identification information identifies whether the access point device 102 supports communication in the auxiliary channel within the individual TWT SP, that is, the seventh identification information identifies whether the access point device 102 is the SST mechanism.

[0173] Typically, TWT modes include individual TWT and broadcast TWT. Individual TWT refers to a one-to-one TWT SP established between the AP and the STA, which can be initiated by the STA to actively initiate a TWT SP establishment request or can be triggered unilaterally by the AP. In the embodiment of the present disclosure, the access point device 102 indicates through the second wireless frame that it supports communication on the auxiliary channel within the individual TWT SP, so that the site device 101 can communicate with the access point device 102 on the auxiliary channel in the individual TWT SP.

[0174] In some embodiments, the seventh identification information is carried in a UHR capabilities information element of the second radio frame.

[0175] The second wireless frame may include a UHR capabilities information element, and the UHR capabilities information element may be used to carry seventh identification information. For example, the seventh identification information may be carried in the UHR capabilities information element field, occupying one bit to carry the seventh identification information. If the seventh identification information is set to "0", it indicates that the access point device 102 does not support communication on the auxiliary channel within the individual TWT SP; if the seventh identification information is set to "1", it indicates that the access point device 102 supports communication on the auxiliary channel within the individual TWT SP.

[0176] In some embodiments, the UHR capabilities information element includes eighth identification information, where the eighth identification information identifies a maximum operating channel bandwidth parameter supported by the AP.

[0177] For example, the UHR capabilities information element is used to carry the second identification information, and 2 bits are used to carry the second identification information. If the seventh identification information is set to "00", it indicates that the access point device 102 supports a maximum channel bandwidth of 160 MHz; if the seventh identification information is set to "01", it indicates that the access point device 102 supports a maximum channel bandwidth of 320 MHz; if the seventh identification information is set to "10", it indicates that the access point device 102 supports a maximum channel bandwidth of 640 MHz.
