[0060] The embodiments of the present disclosure provide a communication method, an access point device, a station device, and a communication device.
[0061] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:
[0062] The access point device determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information includes first listening capability information of the access point device;
[0063] The first listening capability information identifies whether the access point device supports the site device listening to the auxiliary channel;
[0064] The first radio frame is sent.
[0065] In the above embodiment, when the primary channel is busy, the WLAN device can communicate in the secondary channel to improve the throughput of the communication system and maximize the utilization of channel resources.
[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the first listening capability information identifies that the access point device supports the station device listening to the auxiliary channel,
[0067] The first identification information further includes: first listening cycle information, where the first listening cycle information includes listening cycle information for the site device supported by the access point device to listen to an auxiliary channel.
[0068] In the above embodiment, the listening period can be 0 ms (milliseconds), 2.7 ms, or 4 ms, or other time values. The first listening capability information also identifies the listening period times of the station devices supported by the access point device, or the listening period time finally determined by the access point device. By negotiating the listening period time, the mechanism for WLAN devices to communicate on the auxiliary channel is further improved to improve the communication system throughput.
[0069] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes at least one of a beacon frame, a probe response frame, an association response frame, or a newly defined radio frame;
[0070] The first listening period information is carried in the association response frame;
[0071] The newly defined radio frame is a radio frame sent after the initial association.
[0072] In the above embodiment, during the initial association process, the access point device and the station device negotiate the listening capability information of the access point device using at least one of the aforementioned beacon frames, probe response frames, and association response frames. The newly defined radio frames are radio frames sent after the initial association. After the initial association, the listening capability information of the access point device is negotiated using the newly defined radio frames to improve the throughput of the communication system.
[0073] In conjunction with some embodiments of the first aspect, in some embodiments, the first listening cycle information includes a plurality of listening cycle times of the auxiliary channels;
[0074] The listening cycle time of each auxiliary channel is the same, or the listening cycle time of at least two auxiliary channels with different bandwidths is different.
[0075] In the above embodiment, the auxiliary channel may include one or more. For example, if the division is based on 20MHz as the basic bandwidth unit, when the channel bandwidth is 20MHz, there is only one main channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, a channel with a bandwidth of 20MHz is included as the main channel, and the remaining one or more 20MHz channels are auxiliary channels. For different auxiliary channels, the listening cycle time of each of the auxiliary channels can be the same, for example, 2.7ms or 4ms; or there may be at least two auxiliary channels with different bandwidths and different listening cycle times, for example, the listening cycle of the auxiliary channel of 20MHz is 2.7ms, and the listening cycle of the auxiliary channel of 40MHz is 4ms. By negotiating the listening cycle time, the mechanism of WLAN devices communicating in the auxiliary channel is further improved to improve the throughput of the communication system.
[0076] In combination with some embodiments of the first aspect, in some embodiments, the first listening cycle information includes a bandwidth difference between the auxiliary channel and the main channel, and each bandwidth difference corresponds to a preset listening cycle time.
[0077] In the above embodiment, the listening period of the auxiliary channel can be determined by the difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel; for example, a mapping relationship between the bandwidth difference and the listening period difference is established. For every 20MHz difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel, the listening period length increases by 1ms, or the interval between the listening periods increases by 1ms. For channels with different bandwidths, different listening period times are set to reduce mutual interference.
[0078] In conjunction with some embodiments of the first aspect, in some embodiments, the first listening cycle information includes a listening cycle time of the auxiliary channel;
[0079] The listening cycle time is a value configured in the BSS loading information of the primary channel.
[0080] In the above embodiment, the AP and the STA may adjust their listening cycle information to a fixed listening cycle according to the BSS loading information in the primary channel; for example, a configured value in the BSS loading information is selected as the final listening cycle time.
[0081] In conjunction with some embodiments of the first aspect, in some embodiments, the first listening cycle information includes a listening cycle time of the auxiliary channel;
[0082] The listening cycle time of the auxiliary channel is different from the listening cycle time of other BSSs, and the other BSSs are BSSs in the same OBSS as the access point device.
[0083] In the above embodiment, the listening period of the BSS ultimately determined by the access point device and the station device is different from the listening period of other BSSs, thereby avoiding interference with other BSSs. In addition, the access point device broadcasts the negotiated listening period to other WLAN devices in the OBSS, allowing other WLAN devices to determine the listening period of their own BSS based on the received listening period of other BSSs, thereby avoiding interference with other BSSs.

[0160] FIG1 is a schematic diagram showing a communication method according to an embodiment of the present disclosure.
[0161] As shown in Figure 1, in a WLAN, channels are typically divided into primary channels and secondary channels (or non-primary channels, or secondary channels, non-primary channels); a primary channel is, for example, the primary 20 MHz channel in Figure 1; wherein, a secondary channel may include one or more sub-channels, such as the 20 MHz secondary channel and the 40 MHz secondary channel in Figure 1.
[0162] During channel contention, if the primary channel is in an OBSS busy state (OBSS interference), as shown in time periods T1 and T2 in the figure, for example, if it is occupied by other devices in the same OBSS as the WLAN and these other devices are sending physical protocol data units (PPDUs) on the primary channel, the primary channel is in an OBSS busy state. If the primary channel is in an OBSS busy state, to fully utilize channel resources, communication can be switched to a secondary channel to improve system throughput and maximize channel resource utilization. For example, switching to a 20MHz secondary channel during time period T1 or a 40MHz secondary channel during time period T2 can be used.
[0163] If the primary channel is idle, as shown in the T3 time period in the figure, the AP and STA can send PPDUs to each other.

[0168] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network.

[0170] 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.
[0171] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG2 , or a portion thereof, but are not limited thereto. The entities shown in FIG2 are illustrative only. The communication system may include all or part of the entities shown in FIG2 , or may include other entities outside of FIG2 . The number and form of the entities are arbitrary. The entities may be physical or virtual. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0172] 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.
[0173] As shown in FIG2 , the above method includes:
[0174] In step 201, the access point device 102 determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information includes first listening capability information of the access point device; the first listening capability information identifies whether the access point device supports the site device listening to the auxiliary channel.
[0175] In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels). A secondary channel can contain one or more sub-channels. For example, if the basic bandwidth unit is 20 MHz, when the channel bandwidth is 20 MHz, there is only one primary channel with a bandwidth of 20 MHz. When the channel bandwidth is greater than 20 MHz, there is one channel with a bandwidth of 20 MHz as the primary channel, and the remaining one or more 20 MHz channels are secondary channels. The primary 20 MHz channel is the common channel of operation for stations that are members of the basic service set (BSS). Stations in the BSS can compete for channels on the primary 20 MHz channel to seize channel resources.
[0176] During the channel contention process, if the primary channel is in the OBSS busy state, for example, if it is occupied by other devices in the same OBSS as access point device 102 and other devices are sending physical layer protocol data units (PPDUs) on the primary channel, then the primary channel is in the OBSS busy state. If the primary channel is in the OBSS busy state, in order to fully utilize channel resources, the secondary channel can be switched to communicate with site device 101, and site device 101 can be scheduled to the secondary channel. Data can be sent and received with site device 101, thereby improving communication system throughput and maximizing channel resource utilization.
[0177] In the embodiment of the present disclosure, in order to switch to the auxiliary channel for communication when the primary channel is busy, the access point device 102 identifies its first listening capability information in the first radio frame, and the first listening capability information identifies whether the access point device 102 supports the site device 101 to sense the auxiliary channel.
[0178] Typically, before sending data, each station device on the network must listen to see if there is other data being transmitted on the channel, for example, through a carrier sense mechanism. When about to switch to the auxiliary channel for communication, the access point device 102 will notify the station device 101, for example, by sending a request to send (RTS) frame or a buffer status report poll (BSRP) control frame to the station device 101. When the access point device 102 sends the RTS frame or BSRP control frame, the station device 101 needs to listen on the auxiliary channel to receive the RTS frame or BSRP control frame; therefore, to switch to the auxiliary channel for communication when the primary channel is busy, the access point device 102 needs to support the station device 101 to sense the auxiliary channel.
[0179] The first listening capability information indicates whether the access point device supports the site device listening to the auxiliary channel. For example, a first flag bit is set in the first listening capability information. If the first flag bit is set to "1", it indicates that the access point device 102 supports the site device 101 listening to the auxiliary channel, and can subsequently switch to the auxiliary channel for communication when the primary channel is busy. If the first flag bit is set to "0", it indicates that the access point device 102 does not support the site device 101 listening to the auxiliary channel, and cannot subsequently switch to the auxiliary channel for communication when the primary channel is busy.
[0180] Optionally, the first wireless frame may be a frame sent by the access point device 102 and the site device 101 during the initial association process, such as a beacon frame, a probe response frame, an association response frame, or at least one of a newly defined wireless frame; and a new wireless frame may also be newly defined after the initial association to carry the first identification information.
[0181] Step 202: The access point device 102 sends the first wireless frame.
[0182] The access point device 102 sends the first wireless frame. In this way, when the primary channel is busy, the WLAN device can communicate in the secondary channel. For example, when non-periodic data transmission occurs between the access point device 102 and the site device 101, or when the access point device 102 has downlink data to send to the site device 101, when the WLAN device senses that the primary channel is busy, it can switch to the secondary channel to send an RTS or BSRP control frame. The site device 101 listens on the secondary channel and replies with a clear to send (CTS) frame to the access point device 102, so that the access point device 102 confirms that the secondary channel is idle according to the CTS frame and can send data, thereby realizing communication in the secondary channel, thereby improving the throughput of the communication system and maximizing the utilization of channel resources.
[0183] Step 203: The station device 101 receives the first radio frame.
[0184] After receiving the first wireless frame, the site device 101 determines whether the access point device 102 supports the site device listening to the auxiliary channel based on the first listening capability information; if supported (and the site device 101 itself also supports it), it performs listening on the auxiliary channel, for example, through clear channel assessment (CCA) operation, energy detection (ED) operation or network allocation vector (NAV) operation listening.
[0185] In some embodiments, the first listening capability information indicates that the access point device supports the station device to listen to the auxiliary channel.
[0186] The first identification information further includes: first listening cycle information, where the first listening cycle information includes listening cycle information for the site device supported by the access point device to listen to an auxiliary channel.
[0187] The listening period can be 0ms (milliseconds), 2.7ms or 4ms, or other time values. The first listening capability information also identifies the listening period time of the station device 101 supported by the access point device 102, or the listening period time finally determined by the access point device 102.
[0188] In some embodiments, the first radio frame includes at least one of a beacon frame, a probe response frame, an association response frame, or a newly defined radio frame; for example, during the initial association process, the access point device 102 and the site device 101 negotiate the listening capability information of the access point device 102 through at least one of the aforementioned beacon frame, probe response frame, and association response frame; the newly defined radio frame is a radio frame sent after the initial association, and after the initial association, the listening capability information of the access point device 102 is negotiated through the newly defined radio frame.
[0189] The first listening cycle information is carried in the association response frame. For example, the listening cycle time to be finally executed is determined through the association response.
[0190] In some embodiments, the first listening cycle information includes a plurality of listening cycle times of the auxiliary channels;
[0191] The listening cycle time of each auxiliary channel is the same, or the listening cycle time of at least two auxiliary channels with different bandwidths is different.
[0192] The auxiliary channel may include one or more channels.
[0193] For example, if 20MHz is used as the basic bandwidth unit for division, when the channel bandwidth is 20MHz, there is only one main channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, a channel with a bandwidth of 20MHz is included as the main channel, and the remaining one or more 20MHz channels are auxiliary channels. For different auxiliary channels, the listening cycle time of each auxiliary channel can be the same, for example, 2.7ms or 4ms, so that the WLAN device can uniformly manage the listening cycles of different channels; there can also be at least two auxiliary channels with different bandwidths with different listening cycle times, for example, the listening cycle of the auxiliary channel of 20MHz is 2.7ms, and the listening cycle of the auxiliary channel of 40MHz is 4ms. Different listening cycle times are set for channels with different bandwidths to reduce mutual interference.
[0194] In some embodiments, the first listening cycle information includes a bandwidth difference between the auxiliary channel and the main channel, and each bandwidth difference corresponds to a preset listening cycle time.
[0195] The listening period of the auxiliary channel can be determined by the difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel. For example, a mapping relationship between the bandwidth difference and the listening period difference is established. For every 20MHz difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel, the listening period length increases by 1ms, or the interval between the listening periods increases by 1ms.
[0196] In some embodiments, the first listening cycle information includes a listening cycle time of the auxiliary channel;
[0197] The listening cycle time is a value configured in the BSS loading information of the primary channel.
[0198] The AP and STA may adjust their listening cycle information to a fixed listening cycle according to the BSS loading information in the primary channel; for example, a configured value in the BSS loading information may be selected as the final listening cycle time.
[0199] In some embodiments, the first listening cycle information includes a listening cycle time of the auxiliary channel;
[0200] The listening cycle time of the auxiliary channel is different from the listening cycle time of other BSSs, and the other BSSs are BSSs in the same OBSS as the access point device.
[0201] The listening period of the BSS ultimately determined by the access point device 102 and the station device 101 is different from the listening period of other BSSs to avoid interference with other BSSs. In addition, the access point device 102 broadcasts the negotiated listening period to other WLAN devices in the OBSS, allowing other WLAN devices to determine the listening period of their own BSS based on the received listening periods of other BSSs.
[0202] FIG3 is a second interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the method includes:
[0203] In step 301, the site device 101 determines a second radio frame; wherein the second radio frame includes second identification information, the second identification information includes second listening capability information of the site device; the second listening capability information includes whether the site device supports listening to an auxiliary channel.
[0204] In WLAN, channels are usually divided into primary channels and secondary channels (or non-primary channels). A secondary channel can contain one or more sub-channels. For example, if the basic bandwidth unit is 20 MHz, when the channel bandwidth is 20 MHz, there is only one primary channel with a bandwidth of 20 MHz. When the channel bandwidth is greater than 20 MHz, there is one channel with a bandwidth of 20 MHz as the primary channel, and the remaining one or more 20 MHz channels are secondary channels. The primary 20 MHz channel is the common channel of operation for stations that are members of the basic service set (BSS). Stations in the BSS can compete for channels on the primary 20 MHz channel to seize channel resources.
[0205] During the channel contention process, if the primary channel is in the OBSS busy state, for example, if it is occupied by other devices in the same OBSS as access point device 102 and other devices are sending physical layer protocol data units (PPDUs) on the primary channel, then the primary channel is in the OBSS busy state. If the primary channel is in the OBSS busy state, in order to fully utilize channel resources, the secondary channel can be switched to communicate with site device 101, and site device 101 can be scheduled to the secondary channel. Data can be sent and received with site device 101, thereby improving communication system throughput and maximizing channel resource utilization.
[0206] In the embodiment of the present disclosure, in order to switch to the auxiliary channel for communication when the primary channel is busy, the access point device 102 identifies its second listening capability information in the second radio frame, and the second listening capability information identifies whether the site device supports sensing the auxiliary channel.
[0207] Typically, before sending data, each station device on the network must listen to whether there is other data being transmitted on the channel, for example, through a carrier sense mechanism. When switching to the auxiliary channel for communication, the access point device 102 will notify the station device 101, for example, by sending a request to send (RTS) frame or a buffer status report poll (BSRP) control frame to the station device 101. When the station device 101 sends the RTS frame or the BSRP control frame, the station device 101 needs to listen on the auxiliary channel to receive the RTS frame or the BSRP control frame; therefore, to switch to the auxiliary channel for communication when the primary channel is busy, the station device 101 needs to support sensing the auxiliary channel.
[0208] The second listening capability information identifies: whether the site device supports listening to the auxiliary channel; for example, a second identification bit is set in the second listening capability information. If the second identification bit is set to "1", it indicates that the site device 101 supports listening to the auxiliary channel, and can subsequently switch to the auxiliary channel for communication when the main channel is busy; if the second identification bit is set to "0", it indicates that the site device 101 does not support listening to the auxiliary channel, and cannot subsequently switch to the auxiliary channel for communication when the main channel is busy.
[0209] Optionally, the second wireless frame can be a frame sent by the access point device 102 and the site device 101 during the initial association process, such as a probe response probe request frame, an association response association request frame, or at least one of a newly defined wireless frame; and after the initial association, a new wireless frame can be defined to carry the second identification information.
[0210] Step 302: The site device 101 sends the second radio frame.
[0211] Among them, the site device 101 sends the second wireless frame. In this way, when the primary channel is busy, the WLAN device can communicate in the secondary channel. For example, when non-periodic data transmission occurs between the access point device 102 and the site device 101, or when the access point device 102 has downlink data to send to the site device 101, when the WLAN device senses that the primary channel is busy, it can switch to the secondary channel to send an RTS or BSRP control frame. The site device 101 listens on the secondary channel and replies with a clear to send (CTS) frame to the access point device 102, so that the access point device 102 confirms that the secondary channel is idle according to the CTS frame and can send data, thereby realizing communication in the secondary channel, thereby improving the throughput of the communication system and maximizing the utilization of channel resources.
[0212] Step 303: The access point device 102 receives the second radio frame.
[0213] After receiving the second radio frame, the access point device 102 determines whether the access point device 102 supports the site device listening to the auxiliary channel based on the second listening capability information; if supported (and the site device 101 itself also supports it), it performs listening on the auxiliary channel, for example, through a clear channel assessment (CCA) operation, an energy detection (ED) operation, or a network allocation vector (NAV) operation.
[0214] In some embodiments, the second listening capability information indicates that the site device supports listening to an auxiliary channel.
[0215] The second identification information further includes: second listening cycle information, where the second listening cycle information includes listening cycle information of a supplementary channel supported by the site device.
[0216] The listening period may be 0ms (milliseconds), 2.7ms or 4ms, or other time values. The second listening capability information also identifies the listening period time supported by the site device 101, or the finally determined listening period time.
[0217] In some embodiments, the second radio frame includes at least one of a probe request frame, an association request frame, or a newly defined radio frame; for example, during the initial association process, the access point device 102 and the site device 101 negotiate the listening capability information of the access point device 102 through at least one of the aforementioned, probe request frame, and association request frame; the newly defined radio frame is a radio frame sent after the initial association, and after the initial association, the listening capability information of the access point device 102 is negotiated through the newly defined radio frame.
[0218] The second listening cycle information is carried in the association request frame. For example, the listening cycle time supported by the site device 101 is determined through the association request.
[0219] In some embodiments, the second listening cycle information includes a plurality of listening cycle times of the auxiliary channels;
[0220] The listening cycle time of each auxiliary channel is the same, or the listening cycle time of at least two auxiliary channels with different bandwidths is different.
[0221] Among them, the auxiliary channel can include one or more. For example, if the division is based on 20MHz as the basic bandwidth unit, when the channel bandwidth is 20MHz, there is only one main channel with a bandwidth of 20MHz; when the channel bandwidth is greater than 20MHz, it includes a channel with a bandwidth of 20MHz as the main channel, and the remaining one or more 20MHz channels are auxiliary channels. For different auxiliary channels, the listening cycle time of each auxiliary channel can be the same, for example, 2.7ms or 4ms, so that the WLAN device can uniformly manage the listening cycles of different channels; there can also be at least two auxiliary channels with different bandwidths and different listening cycle times, for example, the listening cycle of the auxiliary channel of 20MHz is 2.7ms, and the listening cycle of the auxiliary channel of 40MHz is 4ms. For channels with different bandwidths, different listening cycle times are set to reduce mutual interference.
[0222] In some embodiments, the second listening cycle information includes a bandwidth difference between the auxiliary channel and the primary channel, and each bandwidth difference corresponds to a preset listening cycle time.
[0223] The listening period of the auxiliary channel can be determined by the difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel. For example, a mapping relationship between the bandwidth difference and the listening period difference is established. For every 20MHz difference between the bandwidth of the auxiliary channel and the bandwidth of the main channel, the listening period increases by 1ms.
[0224] In some embodiments, the second listening cycle information includes a listening cycle time of the auxiliary channel;
[0225] The listening cycle time is a value configured in the BSS loading information of the primary channel.
[0226] The AP and STA may adjust their listening cycle information to a fixed listening cycle according to the BSS loading information in the primary channel; for example, a configured value in the BSS loading information may be selected as the final listening cycle time.
[0227] In some embodiments, the second listening cycle information includes a listening cycle time of the auxiliary channel;
[0228] The listening cycle time of the auxiliary channel is different from the listening cycle time of other BSSs, and the other BSSs are BSSs in the same OBSS as the site device.
[0229] The listening period of the BSS ultimately determined by the access point device 102 and the station device 101 is different from the listening period of other BSSs to avoid interference with other BSSs. In addition, the station device 101 broadcasts the negotiated listening period to other WLAN devices in the OBSS, so that other WLAN devices can determine the listening period of their own BSS based on the received listening periods of other BSSs.
