Description

[0002] Currently, research on Wi-Fi technology includes topics such as Ultra High Reliability (UHR), with the vision of improving the reliability of Wireless Local Area Networks (WLAN) connections, reducing latency, improving manageability, increasing throughput at different signal-to-noise ratio (SNR) levels, and reducing device-level power consumption.

[0003] In the UHR (Unified Receiver Network), a distributed resource unit (dRU) is proposed to improve communication transmission distance. Furthermore, to improve spectrum utilization efficiency, i.e., to maximize bandwidth usage, puncturing bandwidth can be employed for transmission. For example, in an 80MHz bandwidth, puncturing 20MHz allows transmission through the remaining 60MHz. Therefore, it is necessary to refine the mechanism for whether the dRU can transmit within puncturing bandwidth, and at what bandwidth, to meet the transmission requirements of the UHR.

[0055] The first wireless frame is sent to the AP.

[0056] In the above embodiment, after receiving the first radio frame sent by the STA, the AP can obtain the STA's support capability information for dRU transmission under the punched bandwidth, and then perform the dRU transmission process under the punched bandwidth according to the capability information, thereby improving spectrum utilization and meeting UHR requirements.

[0149] As shown in Figure 1, the communication system 100 includes a station (STA) 101 and an access point (AP) 102.

[0150] In some embodiments, site device 101 may include, 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.

[0151] In some embodiments, access point device 102 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.

[0152] Specifically, site device 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 101 can support multiple 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.

[0153] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple connections. 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 connection communication functions, and non-AP MLD can represent a station that supports multiple connection communication functions.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, taking the communication system shown in Figure 1 as an example, the above method includes:

[0158] Step 201: During the process of establishing an initial association between the STA and the AP, the site device STA determines the first radio frame; wherein, the first radio frame identifies: the STA's support capability information for dRU transmission under punched bandwidth.

[0159] Optionally, the basic bandwidth of a channel unit is typically 20MHz, but some devices support operating bandwidths, such as 80MHz or higher obtained through channel bonding. To improve spectrum utilization or throughput, punctured channel transmission can be used.

[0160] Prior to 802.11be, in combined channels after channel bonding, if one channel was interfered with, the combined channels would become unusable and could not be combined into a wider bandwidth channel. For example, referring to Figure 3a, in a 160MHz channel, if the 20MHz secondary channel was interfered with, it could not be combined with the 20MHz primary channel. Consequently, the remaining 40MHz and 80MHz secondary channels would also become unusable, resulting in a waste of channel resources.

[0161] To address the aforementioned issues and maximize bandwidth utilization, punctured channels can be employed for transmission. This involves puncturing the preamble, effectively shielding the interfered channel by puncturing it. This allows the unpunctured channels in the combined channel to be used, and can also be combined to create a wider bandwidth channel, thus improving the anti-interference capability of information transmission. Information can still be transmitted quickly even in interference environments. For example, as shown in Figure 3b, in a 160MHz channel, shielding the 20MHz auxiliary channel does not affect the formation of a wider main channel. The 20MHz main channel can still form a 60MHz main channel with the 40MHz auxiliary channel, and then a 140MHz channel with the 80MHz auxiliary channel.

[0162] In UHR, to further improve the communication transmission distance, a distributed radio unit (dRU) is proposed. Access point equipment can use various dRU formats to allocate dRUs to site equipment, which is beneficial to improving the allocation flexibility of dRUs. At the same time, site equipment uses dRUs for uplink data transmission, which is beneficial to improve the power spectral density (PSD), increase the system transmission distance, and improve resource utilization.

[0163] However, the current method of transmission using punctured channels is applicable to the transmission of MU PPDU (Multi-User Physical Layer Protocol Data Unit), but not to the transmission of TB PPDU (Trigger-Based Presentation Protocol Data Unit). For example, it is not possible to use dRU (Distributed Radio Unit) for trigger-based uplink transmission under punctured bandwidth. Signaling needs to be standardized to meet this requirement.

[0164] Optionally, the STA's support capability information for dRU transmission under puncturing bandwidth may specifically include the STA's support capability information for dRU transmission when puncturing in combined channels such as 40MHz, 80MHz, 160MHz and 320MHz.

[0165] In this embodiment of the disclosure, during the initial association between the STA and the AP, the STA determines the first radio frame; the first radio frame identifies the STA's support capability information for dRU transmission under the puncturing bandwidth; in this way, the signaling specification can be adopted to provide the STA's support capability information for dRU transmission under the puncturing bandwidth, thereby satisfying the requirement of trigger-based uplink transmission using dRU under the puncturing bandwidth during the transmission of TB PPDU, improving spectrum utilization and meeting UHR requirements.

[0166] Optionally, in some embodiments, the first wireless frame includes a first identifier bit;

[0167] The parameter value of the first identifier bit is set to the first parameter value, and the first wireless frame identifier indicates that the STA supports dRU transmission under punch-hole bandwidth.

[0168] The parameter value of the first identifier bit is set to the second parameter value, and the first wireless frame identifier indicates that the STA does not support dRU transmission under punch-hole bandwidth.

[0169] Optionally, in some embodiments, the first identifier bit is carried in the UHR capabilities information element of the first radio frame.

[0170] Optionally, the first parameter value can be a pre-configured parameter value or a pre-agreed parameter value, and this embodiment of the present disclosure does not impose any restrictions on this. Similarly, the second parameter value can be a pre-configured parameter value or a pre-agreed parameter value, and this embodiment of the present disclosure does not impose any restrictions on this.

[0171] As an example, the first identifier bit may include a single bit, and when this bit is set to "1", it indicates that the parameter value of the first identifier bit is a first parameter value, corresponding to the first radio frame indicating that the STA supports dRU transmission under punch-hole bandwidth. When this bit is set to "0", it indicates that the parameter value of the first identifier bit is a second parameter value, corresponding to the first radio frame indicating that the STA does not support dRU transmission under punch-hole bandwidth.

[0172] Optionally, in some embodiments, when the STA supports dRU transmission under puncturing bandwidth, the density of puncturing channels supported by the STA is associated with the bandwidth of the STA for uplink TB PPDU transmission.

[0173] Optionally, when using dRU for transmission with a bandwidth greater than 160MHz, the gain of PSD (Power Spectral Density) decreases, which in turn reduces transmission reliability. Therefore, if the STA supports dRU transmission within the puncturing bandwidth, the density of the puncturing channel supported by the STA can be determined based on the bandwidth of the STA's uplink TB PPDU transmission.

[0174] Optionally, if the STA supports dRU transmission under puncturing bandwidth, the wider the bandwidth for uplink TB PPDU transmission by the STA, the greater the density of puncturing channels supported by the STA.

[0175] Optionally, the number of punctured channels supported by the STA is related to the density of punctured channels supported by the STA and the bandwidth of the STA for uplink TB PPDU transmission. Specifically, when the bandwidth of the STA for uplink TB PPDU transmission is fixed, the higher the density of punctured channels supported by the STA, the fewer punctured channels the STA supports.

[0176] Optionally, in some embodiments, the bandwidth for uplink TB PPDU transmission by the STA is 320MHz, and the density of the punched channel supported by the STA is 40MHz or 80MHz.

[0196] Referring to Figure 4i or 4j, when the bandwidth of the uplink TB PPDU is 40MHz, of which the main channel is 20MHz, and the density of the puncturing bandwidth supported by the STA is 20MHz, the puncturing channel with a bandwidth of 20MHz supported by the STA can be the puncturing channel shown in Figure 4i or 4j.

[0197] Step 202: The STA sends the first wireless frame to the AP.

[0198] Step 203: During the process of establishing an initial association between the AP and the STA or after the initial association is completed, the AP determines a second radio frame; wherein, the second radio frame includes second identification information, which identifies the channel information of the punched channel in the BSS bandwidth supported by the AP.

[0199] In some embodiments, the second identification information is carried in the UHR operation information element or the UHR capabilities information element of the second radio frame.

[0200] Optionally, in some embodiments, the second identification information includes a punch information field, which includes a punch channel bitmap.

[0201] The punched channel bitmap includes at least one second identifier bit, and the number of the second identifier bits corresponds one-to-one with the channel units in the BSS bandwidth.

[0202] The parameter value of the second identifier bit is set to the third parameter value, indicating that the channel unit corresponding to the second identifier bit is a punched channel.

[0203] Optionally, the identifier bits in the punched channel bitmap can be bit bits, that is, in the punched channel bitmap, each bit bit corresponds one-to-one with a channel element in the BSS bandwidth supported by the AP.

[0204] Optionally, the bandwidth of the channel unit is 20MHz, and the number of bits in the punched channel bitmap can be set according to the BSS bandwidth supported by the AP.

[0205] For example, with an AP supporting a BSS bandwidth of 40MHz, the punctured channel bitmap can include two bits. With an AP supporting a BSS bandwidth of 80MHz, the punctured channel bitmap can include four bits. With an AP supporting a BSS bandwidth of 160MHz, the punctured channel bitmap can include eight bits. With an AP supporting a BSS bandwidth of 160MHz, the punctured channel bitmap can include sixteen bits.

[0206] Optionally, the third parameter value can be a pre-configured parameter value or a pre-agreed parameter value, and this embodiment of the present disclosure does not impose any restrictions on it.

[0207] As an example, when the second flag is set to "1", it indicates that the parameter value of the second flag is the third parameter value, and correspondingly, the channel element corresponding to the second flag is a punched channel. When the second flag is set to "0", it indicates that the parameter value of the second flag is the fourth parameter value, and correspondingly, the channel element corresponding to the second flag is a non-punched channel.

[0208] Optionally, the number of channels that the AP can punch is related to the BSS bandwidth supported by the AP. The wider the BSS bandwidth supported by the AP, the more channels that the AP can support punching, and more punched channels can be set.

[0209] Optionally, in some embodiments, the BSS bandwidth is 40MHz, and the punched channel includes any 20MHz channel in the BSS bandwidth;

[0210] The BSS bandwidth is 80MHz, and the punched channel includes at least one 20MHz channel in the BSS bandwidth;

[0211] The BSS bandwidth is 160MHz, and the punched channel includes at least one 20MHz channel in the BSS bandwidth;

[0212] The BSS bandwidth is 320MHz, and the punched channels include up to eight 20MHz channels within the BSS bandwidth.

[0213] Optionally, the AP can set the bandwidth of the puncturing channel within the BSS bandwidth supported by the AP, based on the density of puncturing bandwidth of the STA under different uplink TB PPDUs.

[0214] Optionally, if the AP supports a BSS bandwidth of 40MHz and a punctured channel is configured, the punctured channel can be any 20MHz channel within the BSS bandwidth. The punctured channel bitmap can be 01 or 10, where the channel element corresponding to the second identifier bit with a parameter value of "1" is the punctured channel. For example, if the punctured channel bitmap is 01, the BSS bandwidth supported by the AP can be as shown in Figure 5a.

[0215] Optionally, if the AP supports a BSS bandwidth of 80MHz and a punctured channel is configured, the punctured channel can be at least one 20MHz channel in the BSS bandwidth, and at most three 20MHz punctured channels. For example, if the punctured channel bitmap is 0101, the BSS bandwidth supported by the AP can be as shown in Figure 5b.

[0216] Optionally, if the AP supports a BSS bandwidth of 160MHz and punctured channels are configured, the punctured channels can be at least one 20MHz channel within the BSS bandwidth, and at most seven 20MHz punctured channels. Furthermore, there can be at most two consecutive 20MHz punctured channels (i.e., a punctured channel density of 40MHz). For example, if the punctured channel bitmap is 01010011, the BSS bandwidth supported by the AP can be as shown in Figure 5c.

[0217] Optionally, if the AP supports a BSS bandwidth of 320MHz and punctured channels are configured, the punctured channels can be any 20MHz channel from the 160MHz secondary channels within the BSS bandwidth, with a maximum of eight punctured channels. Furthermore, there can be at most two or four consecutive 20MHz punctured channels (i.e., a punctured channel density of 40MHz or 80MHz). For example, with a punctured channel bitmap of 0000000001111011, the BSS bandwidth supported by the AP can be as shown in Figure 5d.

[0218] Step 204: The AP sends the second radio frame to the STA.

[0219] Step 205: STA sends the first data frame to AP;

[0220] The first data frame includes at least one of the third identification information, the fourth identification information, and the fifth identification information;

[0221] The third identification information indicates that the first data frame is an uplink TB PPDU frame; the fourth identification information indicates that the first data frame is a data frame transmitted by dRU under the punctured bandwidth; the fifth identification information indicates that the channel information of the non-punctured channel in the BSS bandwidth supported by the AP.

[0222] Optionally, the first data frame can be a TB PPDU frame. Optionally, the third, fourth, and fifth identification information can be carried in the preamble of the first data frame.

[0223] Optionally, the first data frame may include a punch information field, which can be used to identify the fourth and fifth identification information.

[0224] Referring to the example above, in the Punch Channel field, when the second flag bit in the Punch Channel bitmap has a parameter value set to the third parameter value, the first data frame is identified as a data frame transmitted by dRU under the punched bandwidth. In the Punch Information field, when the parameter value of the second flag bit in the Punch Channel bitmap is set to the fourth parameter value, the channel element corresponding to the second flag bit is identified as a non-punched channel in the BSS bandwidth supported by the AP.

[0265] Figure 7 is a second schematic flowchart illustrating a communication method according to an embodiment of the present disclosure.

[0266] As shown in Figure 7, the above method can be applied to access point device 102, and the method includes:

[0267] Step 701: During the process of establishing an initial association between the AP and the STA, the access point device (AP) receives a first radio frame sent by the STA; wherein the first radio frame identifies the STA's support capability information for dRU transmission under punched bandwidth.
