[0087] As shown in Figure 1, the communication system 100 includes an access point (AP) 101 and a station (STA) 102.
[0088] In some embodiments, access point device 101 can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device with a Wi-Fi chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.
[0089] In some embodiments, site device 102 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports Wi-Fi communication, a car with Wi-Fi communication capabilities, 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 in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home.
[0090] Specifically, site device 102 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 102 can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation IEEE 802.11 protocol, but is not limited to these.
[0091] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple link communication functions, and non-AP MLD can represent a site that supports multiple link communication functions.
[0092] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0093] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.
[0094] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.
[0095] Figure 2 is one of the interactive schematic diagrams of a resource allocation method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:
[0096] Step 201, the AP determines the first radio frame; wherein, the first radio frame identifies resource information allocated by the AP to one or more STAs when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or greater than the maximum bandwidth required by the STA;
[0097] The resource information includes: DSO channel information allocated to a first STA that supports DSO operation; and / or, bandwidth information allocated to a second STA that does not support DSO operation.
[0098] In practical applications of Wireless Local Area Networks (WLANs), the hardware capabilities of the Access Point (AP) are usually greater than those of the STA (Station). For example, the AP may support a maximum bandwidth of 320MHz, while the STA may only support a maximum bandwidth of 80MHz. Thus, when the AP communicates with the STA, the maximum bandwidth is limited to 80MHz, wasting 240MHz of the AP's supported bandwidth and resulting in reduced spectrum utilization. To address this issue, this embodiment employs Dynamic Subband Operation (DSO), allowing a STA supporting DSO to switch to subband communication within a single Transmit Opportunity (TXOP).
[0099] Specifically, when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or when the maximum bandwidth supported by the AP is greater than the maximum bandwidth required by the STA, the AP allocates resource information to one or more of the STAs. For example, the AP supports 320MHz, STA-a supports 80MHz communication (does not support DSO operation), STA-b supports 80MHz (supports DSO operation), and STA-c supports 160MHz (supports DSO operation). If the AP simultaneously performs uplink and downlink communication with STA-a, STA-b, and STA-c, then the AP can allocate the following bandwidth resources to STA-a, STA-b, and STA-c respectively within a 320MHz bandwidth:
[0100] For STA-a (second STA) that does not support DSO operation, a primary 80MHz channel in the primary 160MHz channel is allocated to it; STA-a can communicate with AP on the primary 80MHz channel in the primary 160MHz channel;
[0101] For STA-b (the first STA) that supports DSO operation, a non-primary (secondary) 80MHz channel is allocated to it; STA-b can communicate with AP on the secondary 80MHz channel of the primary 160MHz channel;
[0102] For STA-c (the first STA) that supports DSO operation, a secondary 160MHz channel is allocated to it; STA-c can communicate with the AP on the secondary 160MHz channel. It is understood that in this embodiment, the resource information allocated by the AP to the first STA indicates a handover delay when the first STA switches from the primary channel to the DSO channel; therefore, when switching to the DSO channel, communication between the AP and the first STA for uplink and downlink begins after the STA switches to the DSO channel.
[0103] The AP allocates resource information to one or more STAs and identifies the resource information in a first radio frame. The resource information includes: DSO channel information allocated to a first STA that supports DSO operation; and / or, bandwidth information allocated to a second STA that does not support DSO operation. For example, in the aforementioned example, the first radio frame is identified as channel information allocated to STA-a, STA-b, and STA-c, respectively, so that the STAs can communicate uplink and downlink with the AP through the corresponding channels according to the resource information to realize DSO operation.
[0104] Step 202: Access point device AP101 sends the first wireless frame.
[0105] The first radio frame includes, for example, an initial control frame and a trigger frame. An initial control frame may include, for example, a multi-user request to send (MU-RTS) frame or a buffer status report poll (BSRP) frame.
[0106] In this embodiment, the AP determines a first radio frame. The first radio frame identifies resource information allocated by the AP to one or more STAs when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or greater than the maximum bandwidth required by the STA. This resource information includes: DSO channel information allocated to a first STA supporting DSO operation; and / or bandwidth information allocated to a second STA that does not support DSO operation. By dynamically allocating subband resources, signal quality and system capacity are improved. Simultaneously, interference between multiple users is addressed, and spectrum utilization is improved.
[0107] In some embodiments, the first wireless frame includes at least one of the following:
[0108] The first identification information identifies the uplink (UL) bandwidth information and / or downlink (DL) bandwidth information supported by the AP;
[0109] The second identification information identifies the type of the first wireless frame as being used to trigger or control the DSO operation;
[0110] The third identification information identifies the DSO channel information allocated to each of the first STAs.
[0111] The first identification information, such as the UL / DL bandwidth identifier, is used to identify the bandwidth value supported by the AP when communicating with multiple STAs (including the first STA that supports DSO operation and the second STA that does not support DSO operation). For example, it can be the maximum bandwidth supported by the AP.
[0112] The second identification information is used to identify the type of the first radio frame and is used to trigger or control the DSO operation.
[0113] The third identification information identifies the DSO channel information allocated to each of the first STAs, such as bandwidth information, SS information, etc.
[0114] In some embodiments, the DSO channel information includes at least one of the following:
[0115] The bandwidth information and frequency location information under the DSO operation;
[0116] The spatial stream (SS) information under the DSO operation;
[0117] The uplink modulation and coding scheme (MCS) information under DSO operation (UL MCS);
[0118] Resource unit (RU) information identifies the resource in which the first STA transmits the response frame of the first radio frame in the DSO channel.
[0119] The DSO channel information includes bandwidth information and frequency location information under the DSO operation. For example, it can be identified by the identifier bit in the user info field of the first radio frame, which includes the bandwidth information and frequency location of the DSO channel of the STA under the DSO operation based on the bandwidth allocation information for the STA. For example, the first identifier information indicates that the AP's UL / DL bandwidth is 320MHz and the STA's working bandwidth is 80MHz. Then the AP can allocate 80MHz of bandwidth from the primary 160MHz for DSO operation. For example, the number of channels that can be allocated to the STA can be determined according to the bandwidth multiple relationship between the AP and the STA, and then the specific channel is identified by bits.
[0120] For example, four bits are used to identify the channels that can be allocated to STAs:
[0121] 0100 indicates that the secondary 80MHz of the primary 160MHz is allocated to the STA;
[0122] Alternatively, any 80MHz within the secondary 160MHz range can be assigned to the STA. For example, 0010 indicates that the first (from low to high frequency) 80MHz within the secondary 160MHz range is assigned to the STA.
[0123] It is understood that in different TXOPs, the DSO channel allocated by the AP to the STA may be the same or different, and this disclosure does not limit this.
[0124] In some embodiments, the resource information is applied within the current TXOP, that is, the first STA can switch to the DSO channel for communication within the current TXOP;
[0125] Alternatively, the resource information may be applied to a service period (SP), whereby the SP includes at least one TXOP, i.e., at least one transmission opportunity, during which the first STA can switch to the DSO channel for communication; the SP may include periodic SPs or non-periodic SPs.
[0126] Figure 3 is a second interactive schematic diagram of a resource allocation method according to an embodiment of the present disclosure. As shown in Figure 3, the method includes:
[0127] Step 301, the AP determines the first radio frame; wherein, the first radio frame identifies resource information allocated by the AP for one or more STAs when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or greater than the maximum bandwidth required by the STA;
[0128] The resource information includes: DSO channel information allocated to a first STA that supports DSO operation; and / or, bandwidth information allocated to a second STA that does not support DSO operation.
[0129] Step 302: The AP sends the first wireless frame.
[0130] Step 303: The first STA sends a response frame to the AP in response to the first radio frame.
[0131] Specifically, the first STA sends a response frame to the AP at the corresponding RU based on the RU information identified by the first radio frame, indicating that the first STA has confirmed the reception of the first radio frame; for example, if the first radio frame is an initial control frame, the response frame can be an initial control response frame.
[0132] Step 304: Perform uplink and downlink data transmission with the first STA based on the DSO channel information.
[0133] Upon receiving the response frame from the first STA, the AP can subsequently perform uplink and downlink data transmission with the first STA on the channel identified by the DSO channel information. For example, the AP supports 320MHz, STA-a supports 80MHz communication (does not support DSO operation), STA-b supports 80MHz (supports DSO operation), and STA-c supports 160MHz (supports DSO operation). The AP can simultaneously perform uplink and downlink communication with STA-a, STA-b, and STA-c. STA-a can communicate with the AP on the primary 80MHz channel within the primary 160MHz channel; STA-b can communicate with the AP on the secondary 80MHz channel within the primary 160MHz channel; and STA-c can communicate with the AP on the secondary 160MHz channel. This dynamic allocation of subband resources improves signal quality and system capacity, while also addressing interference issues between multiple users and improving spectrum utilization.
[0134] It is understood that in the resource information allocated by the AP to the first STA, there is a handover delay when the first STA switches from the primary channel to the DSO channel; therefore, when switching to the DSO channel, the AP and the first STA should start communication after the handover delay.
[0135] In some embodiments, the BSS color value of the PPDU frame transmitted by the AP and the first STA during uplink and downlink data transmission on the DSO channel is consistent with the BSS color value of the Physical Layer Protocol Data Unit (PPDU) frame transmitted in the primary channel.
[0136] Specifically, the BSS color value of the PPDU transmitted during uplink and downlink data transmission in the DSO channel is consistent with the BSS color value of the PPDU frame transmitted in the primary channel, so as to avoid being misidentified as an Intra-BSS frame and affecting data transmission.
[0137] Figure 4 is a third interactive schematic diagram of a resource allocation method according to an embodiment of the present disclosure. As shown in Figure 4, the method includes:
[0138] Step 401: During the initial association process, the STA sends a third radio frame to the AP; the AP sends a second radio frame to the STA. The third and second radio frames are used for capability exchange of DSO operational capabilities.
[0139] The third radio frame includes a DSO operation capability information element, which identifies whether the STA supports the DSO operation.
[0140] The third radio frame includes at least one of a probe request frame, an association request frame, or a reassociation request frame.
[0141] The second radio frame carries DSO operational capability information elements and / or operational capability information bits that activate BSSDSO.
[0142] The DSO operation capability information element and / or the BSSDSO activation operation capability information bit are carried in the MAC field of the UHR capabilities information element in the second radio frame; the DSO operation capability information element is used, for example, to identify whether the AP supports DSO operation; the BSSDSO activation operation capability information bit is used to identify whether the AP activates DSO operation.
[0143] The second radio frame includes at least one of a beacon frame, a probe response frame, an association response frame, or a reassociation response frame.
[0144] In some embodiments,
[0145] The second wireless frame also identifies the maximum bandwidth supported by the AP, for example, carried in the UHR operation capability information element;
[0146] The third radio frame also identifies the maximum bandwidth supported by the STA and / or its ability to receive large-bandwidth PPDUs, which is used by the AP to allocate resource information to it.
[0147] Step 402, the AP determines the first radio frame; wherein, the first radio frame identifies resource information allocated by the AP for one or more STAs when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or greater than the maximum bandwidth required by the STA;
[0148] The resource information includes: DSO channel information allocated to a first STA that supports DSO operation; and / or, bandwidth information allocated to a second STA that does not support DSO operation.
[0149] Step 403: The AP sends the first wireless frame.
[0150] In this embodiment, the AP determines a first radio frame. The first radio frame identifies resource information allocated by the AP to one or more STAs when the maximum bandwidth supported by the AP is greater than the maximum bandwidth supported by the STA, or greater than the maximum bandwidth required by the STA. This resource information includes: DSO channel information allocated to a first STA supporting DSO operation; and / or bandwidth information allocated to a second STA that does not support DSO operation. By dynamically allocating subband resources, signal quality and system capacity are improved. Simultaneously, interference between multiple users is addressed, and spectrum utilization is improved.
