Detailed Description

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The technical solution of the embodiment of the application can be applied to various communication systems, for example: WLAN communication systems, long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD) systems, fifth generation (5th generation,5G) systems, new Radio (NR), future sixth generation (6th generation,6G) systems, and the like.

By way of example, the present embodiments may be applied to WLAN systems, and the present embodiments may be applicable to any of the institute of electrical and electronics engineers (institute of electrical and electronics engineers, IEEE) 802.11 family of protocols employed by WLANs, such as 802.11a/b/g, 802.11n, 802.11ac, 802.11ax, 802.11be, 802.11bf, and future 802.11 protocols. The method provided by the application can be implemented by a communication device in a wireless communication system or a chip or a processor in the communication device, and accordingly, the communication device supports communication adopting an IEEE 802.11 series protocol. Although the embodiments of the present application are primarily described in terms of a network that deploys IEEE 802.11, those skilled in the art will readily appreciate that various aspects of the present application may be extended to other networks employing various standards or protocols, such as BLUETOOTH (Bluetooth), high performance wireless local area networks (local area network, LAN) (high performance radio LAN, HIPERLAN), a wireless standard similar to the IEEE 802.11 standard used primarily in Europe, and wide area networks (wide area network, WAN), WLAN, personal area networks (personal area network, PAN), or other now known or later developed networks. Accordingly, the various aspects provided herein may be applicable to any suitable wireless network regardless of the coverage area and wireless access protocol used.

With the development of communication technologies such as WLAN,4G and 5G, various types of wireless communication devices have been deployed in a large number in daily life. The wireless communication device may include a cell phone, a computer, a wireless router, a smart home device, a wireless sensor, and the like. For example, in a home environment there are often several, tens or even hundreds of wireless communication devices that may collide during communication.

In a WLAN communication system, a CSMA/CA carrier sense technique is generally used to actively avoid collision, so as to reduce the probability of collision. However, in the Wi-Fi multi-user scene, hidden nodes and competition conflict exist, so that a plurality of devices simultaneously perform data transmission, interference packet loss occurs, and Wi-Fi performance and user experience are greatly reduced. Hidden node scenario as shown in fig. 1, stations (STA) 1 and STA2 are located in a signal coverage area of an Access Point (AP), and STA1 and STA2 are connected to the AP, and the AP may communicate with STA1 and STA 2. However, because the STA1 and the STA2 cannot directly communicate due to factors such as distance, for the STA1, the STA2 belongs to a hidden node, for the STA2, the STA1 and the STA2 may send data to the AP at the same time, and the AP may collide when receiving signals, and the AP cannot parse the data at any end of the STA1 and the STA 2.

To prevent collision, the 802.11 protocol allows solving the hidden node problem using a Request To Send (RTS)/Clear To Send (CTS) mechanism. The interaction flow of the RTS/CTS mechanism is shown in fig. 2, in which STA1 to be transmitted data sends an RTS frame to STA2, and after a period of time, STA2 sends a CTS frame to STA1 to clear the transmission channel. After STA1 receives the CTS frame, it sends a data frame (frame) on the transmission channel, and if STA2 correctly receives the data frame, STA2 sends an Acknowledgement (ACK) to STA 1. Although RTS/CTS can effectively solve the problem of hidden nodes, the interaction of RTS/CTS frames can prolong the data interaction process, add additional message overhead, and affect Wi-Fi performance and reliability.

Or to prevent collision, wi-Fi transmissions may employ a distributed coordination function (distributed coordination function, DCF) to contend for the air interface. As shown in fig. 3, in the DCF scheme, a station checks whether a transmission channel is in an idle state or not before attempting to transmit data, and if the transmission channel is in a busy state, the station determines a back-off time (back-off time) by using an exponential back-off (orderly exponential backoff) algorithm, and delays access based on the back-off time to avoid collision. This back-off time is random, but as the number of stations increases, the probability that different stations will be random to the same back-off time increases, which may cause stations to transmit data simultaneously, for example, STA1 and STA x simultaneously back-off for a time slot to transmit data, so that an air interface collision occurs, and the AP cannot resolve the data of the transmission collision, which affects Wi-Fi performance and reliability.

Based on this, the embodiment of the application provides a communication method, in which an access point device allocates a corresponding time slice to at least one station device, and the at least one station device sends a data packet on the corresponding time slice, so that the probability of collision can be reduced, and the Wi-Fi performance and reliability can be improved.

Referring to fig. 4, a communication process provided for an embodiment of the present application includes the following steps:

s401: the access point device generates first information.

Wherein the first information includes information of a time slice allocated to the at least one station apparatus, the time slice being used for the at least one station apparatus to transmit the data packet on the time slice.

S402: the access point device sends first information to at least one site device, and the at least one site device receives the first information.

S403: the station apparatus generates a data packet.

The station device belongs to at least one station device that receives the first information.

S404: and the station equipment sends the data packet to the access point equipment on the time slice included in the first information, and correspondingly, the access point equipment receives the data packet.

The access point device (such as the AP) is a device deployed in a wireless communication system to provide wireless communication functions for its associated station device, and is typically a device supporting the 802.11 system standard, such as a router, gateway, repeater, communication server, switch or bridge, for example.

The above-mentioned station device (such as STA) is a device with a wireless communication function, and is usually an end product supporting the standard of the 802.11 system, such as a mobile phone, a personal computer (personal computer, PC) (also called desktop), a notebook, an entertainment device, a wearable device, a smart home device, or the like.

The at least one station device is a station device that communicates with the access point device, and generally refers to a station device that accesses the access point device or a station device that is located in a signal coverage area of the access point device.

The access point device may determine, through the acquired site information of the site device, a site device in communication with the access point device. The access point device may acquire station information of the station device in the following manner:

mode 1: the access point device receives station information from the station device.

Site information for a site device includes, but is not limited to, one or more of the following: device identification, device type, whether it is a mobile device, location information, data traffic, or packet loss rate, etc. The device identification may be one or more identification information such as a device number, an internet protocol (internet protocol, IP) address assigned to the station device, or a media access control (media access control, MAC) address of the station device. The device type is used to describe the type of site device, for example, in a smart home scenario, the device type includes one or more of the following types: a mobile phone, a desktop, a desk lamp, an air conditioner, a television, a refrigerator or a washing machine, etc. Whether a mobile device is generally referred to as whether the location can be moved during use, e.g., a mobile device such as a cell phone or a notebook computer, or a non-mobile device such as a desktop, desk lamp, or air conditioner. The location information is used to indicate a location where the site device is located, for example, in a smart home scenario, where the location includes one or more locations such as a primary sleeper, a secondary sleeper, a restaurant, or a living room. Data traffic refers to the amount of data transmitted by a station device per unit time. The packet loss rate is the ratio of packets lost per unit time to packets transmitted.

The timing of the station device sending the station information may include one or more of the following:

1.1, when/after the station equipment is accessed to the access point equipment, sending station information of the station equipment to the access point equipment;

1.2 the site equipment periodically transmits site information;

1.3 when/after receiving the location information of the station device configured by the distribution network device, the station device sends the station information of the station device to the access point device.

In the 1.3, a distribution network device (for example, a terminal such as a mobile phone) is used as a distribution network device, and distribution network software is installed, the distribution network software supports the function of editing a house type and the position of setting site equipment (such as which room the device is in), a user can edit a home type diagram of the user based on the distribution network software, and then home equipment is set at the room position in the house type diagram, so that the position information of the site equipment is configured by the terminal. The relevant description of the location information of the configuration site device of the distribution network device is explained later.

Mode 2: the access point device receives site information from a site device configured by the distribution network device.

The timing of the distribution network device sending the site information of the site device may include one or more of the following:

2.1 the distribution network equipment periodically transmits the site information of the site equipment;

2.2 when/after the distribution network equipment configures the position information of the station equipment, the distribution network equipment sends the station information of the station equipment to the access point equipment.

The description of the location information of the configuration site device of the distribution network device is described later.

Optionally, the time slices are time slices allocated to a station device group, where the station device group includes the at least one station device, that is, the at least one station device belongs to one station device group, and the time slices allocated to different station device groups are different. For example, the access point device groups a plurality of station devices in communication therewith to obtain one or more station device groups, wherein each station device group includes one or more station devices, and the access point device assigns a corresponding time slice to each station device group.

In one possible implementation, when the access point device groups the plurality of station devices, the access point device groups the plurality of station devices according to the station information and the grouping policy of the plurality of station devices. By way of example, the grouping policy includes one or more of the following policies:

strategy 1: at least one station apparatus whose location information belongs to the same room is located in one station apparatus group, that is, a time slice is allocated for at least one station apparatus whose location information belongs to the same room.

In this policy 1, the access point device classifies station devices in the same room into one group, for example, the main bedroom includes an air conditioner and a desk lamp, and the access point device may classify the air conditioner and the desk lamp into one group. Typically no hidden nodes will appear between the station devices in the same room.

Strategy 2: one station device belonging to the mobile device is located individually in one station device group, that is, time slices are individually allocated for one station device belonging to the mobile device.

In this policy 2, the access point device divides a mobile device into a group individually, for example, divides a mobile phone and a notebook computer into a group individually. For example, dividing a mobile device into a group in which a bedroom is located, when the mobile device leaves the bedroom, other station devices in the bedroom cannot perceive the mobile device, which may cause the station device and the mobile device in the bedroom to simultaneously send data packets to an access point device, resulting in interference packet loss.

Strategy 3: a site device whose data traffic lies in the first traffic range is located solely in a site device group, that is, a time slice is allocated solely to a site device whose data traffic lies in the first traffic range.

In this policy 3, the access point device individually classifies one station device whose data traffic is in the first traffic range into one group, for example, the desktop is individually classified into one group.

The flow ranges may include, but are not limited to, a first flow range and a second flow range, wherein a minimum value in the first flow range is greater than or equal to a maximum value in the second flow range, that is, a data flow in the first flow range is greater than or equal to a data flow in the second flow range, and for convenience of description, a site device in which the data flow is in the first flow range is referred to as a large flow device, and a site device in which the data flow is in the second flow range is referred to as a small flow device. By way of example, the first flow range and the second flow range may be divided by a flow threshold, data flows above (or not below) the flow threshold being in the first flow range and data flows not above (or below) the flow threshold being in the second flow range, i.e. the flow threshold being the minimum in the first flow range and the maximum in the second flow range. The first flow range and the second flow range are not limited in the embodiments of the present application.

Strategy 4: at least one of the site devices whose data traffic lies in the second traffic range lies in one of the site device groups, that is, the time slices are allocated to at least one of the site devices whose data traffic lies in the second traffic range.

In this policy 4, the access point device groups at least one station device of the second traffic range with data traffic into a group.

Strategy 5: one station device with the packet loss rate in the first packet loss range is separately located in one station device group, that is, one station device with the packet loss rate in the first packet loss range is separately allocated in time slices.

In this policy 5, the access point device divides one station device whose packet loss rate is within the first packet loss range into one group individually.

The packet loss range may include, but is not limited to, a first packet loss range and a second packet loss range, wherein a minimum value in the first packet loss range is greater than or equal to a maximum value of the second packet loss range, that is, a packet loss rate in the first packet loss range is greater than or equal to a packet loss rate in the second packet loss range, for convenience of description, a station device with a packet loss rate in the first packet loss range is referred to as a station device with a high packet loss rate, and a station device with a packet loss rate in the second packet loss range is referred to as a station device with a low packet loss rate. For example, the first packet loss range and the second packet loss range may be divided by a packet loss threshold, where a packet loss rate greater than (or not less than) the packet loss threshold is located in the first packet loss range, and a packet loss rate not greater than (or less than) the packet loss threshold is located in the second packet loss range, that is, the packet loss threshold is the minimum value in the first packet loss range, and the maximum value in the second packet loss range. The first packet loss range and the second packet loss range are not limited.

Strategy 6: at least one station device with a packet loss rate in the second packet loss range is located in one station device group, that is, the time slice is allocated for at least one station device with a packet loss rate in the second packet loss range.

Alternatively, in the case where the above policies do not conflict, the above policies may be used in combination, for example, a plurality of policies 1, 4, and 6 may be used in combination. For example, when policy 1 and policy 4 are used in combination, the location information belongs to the same room, and at least one site device whose data traffic is in the second traffic range is in one site device group.

Optionally, there are different priorities between policies 1-6 above, such as, but not limited to: priority of policy 2 = priority of policy 3 = priority of policy 5 > priority of policy 1 = priority of policy 3 = priority of policy 6.

In one possible implementation, when the access point device allocates a corresponding time slice to each station device (or each group of station devices), each station device (or each group of station devices) may be allocated a slot time slot (slot) in turn. For example, when the access point device allocates time slices for 5 station devices (or 5 groups of station devices), the 1 st time slice of the nth slot (denoted by slotn+1), the 2 nd time slice of the nth slot (denoted by slotn+2), the 3 rd time slice of the nth slot (denoted by slotn+3), the 4 th time slice of the nth slot (denoted by slotn+4), and the 5 th time slice of the nth slot (denoted by slotn+5) may be allocated. Through the allocation of the time slices, each site device (or each group of site devices) can be guaranteed to send data packets in the time slices belonging to the site device, hidden nodes can be avoided, the probability of collision is reduced, and Wi-Fi performance and reliability are improved.

Optionally, the access point device periodically acquires the site information of the site device, and periodically updates the time slice information for the site device according to the site information of the site device. For example, the access point device periodically sends instructions to the station device instructing the station device to feed back station information (e.g., data traffic and/or packet loss rate, etc.). For example, for station devices that are continuously in low traffic, the access point device may allocate fewer time slices, and similarly, for station devices that are in increased traffic, the access point device may allocate more time slices. As another example, for a station device with a high packet loss rate, it may be attempted to separate the station device into a group, and by allocating a separate time slice to it, it is detected whether the packet loss rate is improved. That is, the access point device may dynamically adjust the time slice in combination with the station information of the station device, thereby further reducing the air interface contention conflict.

The following describes embodiments of the present application in detail with reference to a home scenario and a process for configuring a network device. It is to be appreciated that the embodiments of the present application are equally applicable to other scenarios (e.g., without limitation, office scenarios, school scenarios) under Wi-Fi networks. As shown in fig. 5, the AP includes a router, and the STA includes STA1 (cell phone), STA2 (desk lamp), STA3 (air conditioner), STA4 (refrigerator), STA5 (desktop) and STA6 (television). The home scene also comprises distribution network equipment, for example, the distribution network equipment is a mobile phone. The STAs are connected with the AP, hidden nodes may occur between the STAs due to factors such as distance and wall, and since each STA and the AP have data interaction, there may be a situation of air interface contention collision, and the air interface contention collision may be reduced through the following procedure.

The distribution network device is provided with distribution network software, the distribution network software provides a house type editing function, a user interface 600 for editing the house type function can be as shown in fig. 6, and the user interface 600 can comprise a floor editing icon 601, a house type display area 602, a house type editing icon 603 and a storage icon 604. For example, the distribution network device may edit a floor in response to a user operating the floor edit icon 601, where each floor of the floor edit icon 601 is displayed with a thumbnail of the floor type. For another example, the distribution network device may respond to the user operation on the home type editing icon 603 to edit the home type graph, for example, the user may operate on "add room icon" or "home type icon" to edit the home type graph based on the home type of the home, or the user may operate on "empty icon" or "reset icon" to empty or reset the home type displayed in the home type display area 602. As another example, the distribution network device may save the edited house pattern graph in response to an operation on save icon 604.

After the user edits the house type diagram, the network distribution device may prompt to edit the location of each device (i.e. set the room where the device is located), where the user interface 700 for editing the location of the device is shown in fig. 7, and the user selects the room where the device is located in the user interface 700, for example, the network distribution device determines that the current device is located in the living room in response to the user operation on the "living room icon". In addition, the user interface 700 further includes an add room icon 701, and the network device may add an option of a room in which the device is located in response to a user operation of the add room icon 701. Through multiple operations of the user, the positions of the AP and the STAs 1 to STA6 can be set in the home type map, for example, the home type map after setting the device positions is shown in fig. 8, and the device owned by the current user home and the room where each device is located can be known according to fig. 8.

As shown in fig. 9, the network device is further provided with a user interface 900 of AP (router) information, where the user interface 900 includes a house type map display area 901, a network environment display area 902, a network rate display interface 903, an access device display interface 904, and a smart detection icon 905. The residential pattern diagram display area 901 displays the residential pattern diagram and the number of online devices of each room in the residential pattern diagram accessing the router. The access device display interface 904 displays the total number of online devices that access the router. The distribution network device may respond to the user's operation on the smart detection icon 905 to perform smart detection on the device accessing the router in the home type graph.

Each STA or the network allocation device may send the station information of STA1 to STA6 to the AP, and the AP may obtain the station information of STA1 to STA 6. Station information of STA1 to STA6, wherein STA1 (mobile phone) is shown in table 1 below, and STA1 (mobile phone) is not considered to be stationary in a room, and thus is represented by unavailable (NA).

TABLE 1

The AP may group (group) STAs 1 to 6 in combination with the station information in table 1, where in the grouping policy, the mobile devices are individually grouped into one group, because the location of the mobile device may change frequently, and if the mobile device is grouped with other non-mobile devices, the hidden node information may change or fail, which may cause air interface contention conflict; in the grouping strategy, the large-flow site equipment is singly divided into one group, so that air interface competition conflict between the large-flow site equipment and other sites can be avoided; and grouping small-traffic station devices in the same room into a group in a grouping strategy, because station devices in one room generally do not have hidden nodes and do not have the problem of air interface contention conflicts. The grouping results of the APs are shown in table 2 below.

TABLE 2

Packet numbering	STA list	Grouping reason
			Group1	STA1	Mobile device
Group2	STA2、STA3	Small flow device for the same room
			Group3	STA4	With only one device in the room
Group4	STA5	High flow device
			Group5	STA6	High flow device

The AP divides the air interface into a number of time slices as shown in fig. 10 and then allocates the time slices to each group in turn. Wherein the correspondence of each set of site devices to time slices is shown in table 3 below.

TABLE 3 Table 3

Packet numbering	STA list	Time slice
			Group1	STA1	slot1,…,slotn+1
Group2	STA2、STA3	slot2,…,slotn+2
			Group3	STA4	slot3,…,slotn+3
Group4	STA5	slot4,…,slotn+4
			Group5	STA6	slot5,…,slotn+5

The AP sends the time slice information corresponding to each group of site equipment to the site equipment in the group, so that the STA of each group only sends data packets in the time slices belonging to the STA, hidden nodes are avoided, and the collision probability of air interface competition can be reduced.

After completing one grouping, the AP may send an instruction (without limitation in the embodiment of the present application) periodically, to instruct the STA to feed back information such as the traffic size and the packet loss rate, where the AP may combine various station information of the STA to dynamically adjust the time slice. For example, for an STA continuously in a low traffic state, the AP may allocate fewer time slices based on the last time of allocation of a time slice, and similarly for an STA with increased traffic, the AP may allocate more time slices based on the last time of allocation of a time slice; for STAs with high packet loss rate (for example, the packet loss rate is higher than the packet loss rate threshold, where the value of the packet loss rate threshold is not limited), the AP may attempt to separate the STAs into a group, and detect whether the packet loss rate of the STA may be improved.

In the embodiment of the application, the configuration network device can enable the whole network to avoid the hidden node by configuring the position information of the STA, and the AP allocates time slices in combination with the site information such as the device type, the flow requirement and the like of the STA instead of additionally sending the detection frame to detect the hidden node, so that the hidden node and air interface competition can be reduced, the packet loss is reduced, and the network performance and the resource utilization rate are improved.

As can be seen from the foregoing embodiments, the embodiments of the present application are applicable to the system schematic diagram shown in fig. 11, including the network device, the AP, and the STA. Wherein the distribution network equipment is provided with distribution network software, which can provide the functions of the above-mentioned figures 6-9. The distribution network device may send the configured location information of the STA to the information encapsulation module of the STA, where the information encapsulation module of the STA sends the station information of the STA (including the location information of the STA) to the AP through the communication module, the information analysis module of the AP receives the station information of the STA through the communication module, and analyzes the station information of the STA and then transmits the station information of the STA to the packet decision module of the AP, where the packet decision module designates a packet policy and allocates a corresponding time slice to the STA, and then sends the information of the time slice to the STA through the communication module, where the STA receives the information of the time slice through the communication module, and where the packet execution module of the STA sends a data packet according to the time slice.

It should be understood that the structure shown in fig. 11 does not constitute a specific limitation on the distribution network device, the AP, and the STA. For example, in other embodiments of the present application, the distribution network device, the AP, and the STA point may include more or fewer components than shown, or may combine certain components, or split certain components, or may be arranged in different components.
