Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In addition, the plurality of the present application means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used to describe various data in embodiments of the present invention, these data should not be limited by these terms. These terms are only used to distinguish the data from each other.

The method provided by the embodiment of the application can be applied to a Wireless Local Area Network (WLAN) communication system, such as a Wi-Fi communication system.

Fig. 1a is a schematic diagram of a WLAN communication system architecture applied to the method according to the embodiment of the present application. The WLAN communication system includes a wireless Access Point (AP) 101 and a wireless Station (STA) 102. The WLAN communication system may also include a gateway 103. For example, the gateway 103 may be a switch.

The AP101 is a wireless device providing wireless access service and data access, and allows other wireless devices in the wlan communication system to access. The STA102 is a wireless terminal in a wireless local area network accessing the WLAN communication system, such as a mobile phone (mobile phone), a tablet computer, a notebook computer, a handheld computer, a Mobile Internet Device (MID), a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in a smart home (smart home), and the like.

Wireless communication can be carried out between the AP and the AP in the WLAN communication system, and 1 AP can access a plurality of STAs. Another wlan communication system architecture, such as that illustrated in fig. 1b, illustrates that the wlan communication system includes a first AP and a second AP; the first AP and the second AP are in wireless communication; a first STA is accessed under the first AP, and a second STA is accessed under the second AP.

In Wi-Fi technology, wireless devices such as a wireless Station (STA) and a wireless Access Point (AP) transmit or receive signals and data in an air interface by occupying air interface resources. In previous versions of the Wi-Fi technical standard 802.11ax for 2.4G and 5G bands defined by the Institute of Electrical and Electronics Engineers (IEEE), such as 802.11 released in 1997, 802.11b released in 1999 for 2.4G bands and 802.11a released in 5G bands, 802.11G released in 2003 for 2.4G bands and 802.11ac released in 2013 for 5G bands, an AP/gateway and STA in the air interface generally acquire opportunities to occupy air interface resources through competition according to a Distributed Coordination Function (DCF) defined by the WiFi standard. The uplink scheduling is supported from 802.11ax, the uplink and downlink data can be scheduled through the AP/gateway, the STA does not need to compete for opportunities, but the AP and the gateway still need to compete for opportunities. For example, an AP/gateway in the air interface acquires an opportunity to occupy air interface resources through contention according to a Point Coordination Function (PCF) defined by a WiFi standard.

Air interface resources are occupied in a competition-based mode, occupation conflict is easy to occur among wireless devices, occupied opportunities cannot be obtained when the air interfaces are idle, and uncertainty exists. At present, in order to reduce preemption conflict, each wireless device judges whether an air interface is idle, and when the air interface is determined to be idle for the first time, the air interface needs to wait for a certain time before the air interface is determined to be idle again to occupy air interface resources. A schematic diagram of the delayed occupation of air interface resources as illustrated in fig. 2. The wireless device determines that the air interface is changed from a busy state (busy) to an idle state (idle) at T1, waits for an arbitration frame interval (AIFS) and a random backoff time (backoff time) to reach T2, and occupies air interface resources to transmit and receive data, for example, to transmit a frame (frame) over the air interface, if the air interface is still idle.

When there are many wireless devices in the air interface, it takes a long time to acquire the occupation opportunity, and there is uncertainty. For a wireless device that needs to process a service with a low service delay, the service delay is not guaranteed, and the service experience of the wireless device is affected.

Taking the first communication network architecture illustrated in fig. 3 as an example, when DCF is adopted, AP1, STA11, STA12, STA13, AP2, STA21, STA22, and STA23 in fig. 3 all need to acquire the opportunity of occupying air interface resources through contention, and if other wireless devices compete for the air interface within the time of first determining that the air interface is idle for waiting, only waiting can be continued; as shown in fig. 4a, which is a schematic diagram illustrating waiting to occupy an air interface, the AP1 waits for the STA11, the STA13, the AP2, the STA12, and the STA21 to occupy air interface resources before occupying air interface resources. If the AP1 needs to handle low traffic delay traffic, the long latency may affect the traffic experience of the AP 1.

Taking the first communication network architecture illustrated in fig. 3 as an example, when uplink scheduling is adopted, only contention between APs is needed to obtain a chance of occupying air interface resources, an AP and an STA accessing the AP form a scheduling domain, and centralized scheduling can be performed in the scheduling domain represented by the AP within a time period in which the AP occupies the air interface resources, so contention between APs is also contention between the scheduling domains represented by the APs. Fig. 4b is another schematic diagram of waiting for air interface occupation, which illustrates a waiting process between the AP1 and the AP2 for occupying air interface resources. Although the probability of preemption collisions and the waiting time are reduced compared to the DCF, such a method still affects the service experience when services with extremely low service delay, such as VR services, need to be processed, and is limited to the number of APs, and there may still be a long waiting time when the number of APs in the air interface device is large. Therefore, no matter DCF or uplink scheduling is adopted, the opportunity of occupying the air interface resource is obtained through competition, and the air interface occupied by the wireless equipment has uncertainty and needs certain waiting time, so that the air interface efficiency is low, and the service experience of the wireless equipment is not facilitated.

Based on this, the embodiments of the present application provide a method and an apparatus for scheduling air interface resources, which enable a plurality of wireless devices to occupy air interface resources in order, avoid preemption conflicts, reduce uncertainty of the wireless devices occupying the air interface resources, do not need extra waiting time, and are beneficial to improving service experience. Because the principle of solving the problem of the method and the device is the same, the embodiments of the method part and the device part can be mutually referred, and repeated parts are not described again.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 5, an embodiment of the present application provides a method for scheduling air interface resources, where the method is applied to a first wireless device, and the first wireless device may be any one of a plurality of wireless devices that need to occupy the same air interface resource. For example, the first wireless device may be an AP or a STA in the WLAN communication system.

The implementation process of the method is specifically as follows:

step S501, receiving first indication information, where the first indication information is used to indicate that the first wireless device occupies an air interface resource.

Wherein the first indication information may be from other wireless devices communicating with the first wireless device.

Step S502, occupying air interface resources to receive and transmit data.

Step S503, when the first time duration is reached, releasing the air interface resource, and notifying the second wireless device to occupy the air interface resource.

In the embodiment of the application, the wireless device occupies the air interface resource according to the indication, and notifies other wireless devices to occupy when the occupation is finished and the air interface resource is released, the plurality of wireless devices can mutually indicate to occupy the air interface resource to cooperatively receive and transmit data, the air interface resource is occupied through competition without continuously monitoring the state of the air interface, the occupation conflict can be avoided, the uncertainty of the air interface resource occupied by the wireless device is reduced, extra waiting time is not needed, and the air interface efficiency and the service experience are improved.

In an alternative embodiment, the second wireless device is a first wireless device that is behind the first wireless device in an order of occupancy determined according to a network topology in which the first wireless device and the second wireless device are located.

In an alternative embodiment, the first wireless device and the second wireless device are in mutual visibility, i.e. the first wireless device is within the communication range of the second wireless device, which is within the communication range of the first wireless device. Two wireless devices that are visible to each other may also be referred to as two adjacent wireless devices, and it should be noted that in this application, the term "adjacent" does not limit the relative position relationship between two wireless devices.

For convenience of understanding, in the embodiment of the present application, with reference to the network topology schematic diagrams shown in fig. 6 to fig. 8, taking an uplink scheduling manner as an example, an occupation sequence in which a plurality of wireless devices (i.e., APs/gateways) occupy air interface resources is described as follows:

a first network topology as shown in fig. 6, in which the gateway and AP1 are visible to each other, AP1 and AP2 are visible to each other, and the gateway and AP2 are not visible; the scheduling domain represented by AP1 includes two stations, STA1 and STA 2; the scheduling domain represented by AP2 includes a station, STA 3. Optionally, the wireless devices that are visible to each other may be arranged in an adjacent order according to the network topology, and the determined occupation order may be: gateway- > AP1- > AP2- > AP 1.

A second network topology as shown in fig. 7, in which the gateway and AP1 are visible to each other, the gateway and AP2 are visible to each other, and AP1 and AP2 are not visible to each other; the scheduling domain represented by AP1 includes two stations, STA1 and STA 2; the scheduling domain represented by AP2 includes a station, STA 3. Optionally, the wireless devices that are visible to each other may be arranged in an adjacent order according to the network topology, and the determined occupation order may be: gateway- > AP1- > gateway- > AP 2.

A third network topology as shown in fig. 8, in which the gateway, AP1 and AP2 are visible to each other; the scheduling domain represented by AP1 includes two stations, STA1 and STA 2; the scheduling domain represented by AP2 includes a station, STA 3. Optionally, the wireless devices that are visible to each other may be arranged in an adjacent order according to the network topology, and the determined occupation order may be: gateway- > AP1- > AP 2.

In the embodiment of the application, the AP and the gateway, namely the scheduling domain occupy the air interface resources in turn according to the occupied sequence, and centralized scheduling is performed between the AP and the STA in the scheduling domain. No matter the AP or the STA needs to seize the air interface resource through competition, the seizing conflict can be avoided, the orderly occupation of the air interface resource among a plurality of wireless devices is ensured, the uncertainty of the occupation of the air interface resource by the wireless devices is reduced, extra waiting time is not needed, and the air interface efficiency and the service experience are improved.

In an alternative embodiment, the first duration is determined according to a duration control parameter, and the duration control parameter includes one or more of an occupation order, traffic delay requirements of a plurality of wireless devices included in the network topology, and traffic flow of the first wireless device.

For the sake of understanding, the occupation sequence determined according to the first network topology shown in fig. 6, i.e. gateway- > AP1- > AP2- > AP1, is taken as an example: in one round, the gateway and AP2 are only turned to 1 time, while AP1 is turned to 2 times. Determining the occupation time lengths of the gateway, the AP1 and the AP2 according to the occupation sequence, optionally allocating the same occupation time length for the gateway and the AP2, and allocating half of the occupation time length of the AP1 compared with that of the gateway/AP 2; or, if the indication information received by the AP1 is from the gateway, the AP1 may occupy the air interface resource according to the same occupation duration as the gateway; if the indication information received by the AP1 is from the AP2, the AP1 directly sends an indication message to the gateway to notify the gateway to occupy air interface resources.

In addition, determining the occupied time length according to the service delay requirements of a plurality of wireless devices contained in the network topology structure, and if the service delay requirements are higher, shortening the time length of the wireless devices occupying the air interface resources each time; if the service delay requirement is low, the time for the wireless equipment to occupy the air interface resource each time can be increased, so that the utilization rate of the air interface is improved, and higher throughput is obtained.

Optionally, the occupied time length is determined according to service delay requirements of a plurality of wireless devices included in the network topology, and the following implementation may be specifically referred to: setting a single transmission delay of each wireless device, namely, the time length of a single occupied air interface resource meets the following conditions:

single transmission delay < min (service 1 delay, service 2 delay, … service n delay)/number of devices participating in scheduling transmission;

wherein min (service 1 delay, service 2 delay, … service n delay) represents the lowest service delay among the delay requirements of one or more services corresponding to the plurality of wireless devices; the number of devices participating in scheduling transmission, that is, the number of the wireless devices corresponding to the aforementioned occupied sequence.

In the embodiment of the application, the single transmission time delay of each wireless device is determined according to the lowest service time delay in the service time delay requirements of the plurality of wireless devices corresponding to the occupation sequence, so that the service time delay requirements of each wireless device can be met when the plurality of devices occupy the air interface resources in turn according to the occupation sequence.

Optionally, considering that the traffic flows of different wireless devices, such as APs, are different, the duration of occupation of the AP may also be adjusted according to the traffic flow of a single AP.

In an alternative embodiment, a management device that centrally manages a plurality of wireless devices may determine an occupation sequence of the plurality of wireless devices and an occupation duration of each of the plurality of wireless devices, and correspondingly transmit the determined occupation sequence and occupation duration to each of the wireless devices, such as the first wireless device. In specific implementation, the independent wireless device may be used as a management device, or a certain wireless device of the multiple wireless devices may be selected as the management device to determine the occupation sequence and the occupation duration.

In an optional implementation manner, the receiving the first indication information may be implemented specifically by referring to the following implementation manners:

receiving first indication information from a third wireless device, wherein the third wireless device is a wireless device which is adjacent to the first wireless device in the occupied order and is positioned before the first wireless device; alternatively, first indication information is received from the management apparatus.

The above-mentioned notifying that the second wireless device occupies the air interface resource may be implemented specifically by referring to the following manners:

sending second indication information to the second wireless device, wherein the second indication information is used for indicating the second wireless device to occupy the air interface resource; or sending a release signal to the management device to indicate the second wireless device to occupy the air interface resource through the management device; the release signal is used for instructing the first wireless device to release air interface resources.

To facilitate understanding of the interaction relationship between the wireless devices, referring to fig. 9, an exemplary embodiment of the present disclosure provides a wireless device interaction diagram. Specifically, a process in which a first wireless device, a second wireless device, and a third wireless device occupy air interface resources in sequence is illustrated, which includes:

step S901: and the third wireless equipment occupies the air interface resource to receive and transmit data.

Step S902: and the third wireless equipment sends the first indication information to the first wireless equipment to indicate that the first wireless equipment occupies the air interface resources.

Step S903: the first wireless device occupies air interface resources to receive and transmit data.

Step S904: and the first wireless equipment sends second indication information to the second wireless equipment to indicate that the second wireless equipment occupies the air interface resources.

In specific implementation, an uplink scheduling mode is adopted, when the plurality of wireless devices that need to occupy the air interface resource include two wireless devices, the two wireless devices alternately indicate that the other side occupies the air interface resource, the second wireless device and the third wireless device may be the same wireless device, and the second/third wireless devices are only used for distinguishing different occupation sequences of the same wireless device, and are not limited to corresponding different wireless devices.

As shown in the second communication network architecture diagram of fig. 10, the wireless device that needs to occupy air interface resources includes AP1 and AP2 that is adjacent to AP 1; wherein AP1 and AP2 are visible to each other. As shown in fig. 10, STA1 and STA2 are included in the scheduling domain represented by AP 1; STA3 and STA4 are included in the scheduling domain represented by AP 2. When receiving the indication information from the AP2, the AP1 occupies air interface resources to receive and transmit data, for example, to send data to other wireless devices or to complete uplink and downlink data transmission between the AP and the STA in the scheduling domain; after the occupation of the AP1 is finished, the AP2 sends indication information to notify that the scheduling domain represented by the AP2 occupies the air interface resource.

As shown in fig. 11, STA1 and STA2 are included in the scheduling domain represented by AP 1; STA3 and STA4 are included in the scheduling domain represented by AP 2. When receiving the indication information from the AP2, the AP1 occupies air interface resources to receive and transmit data, for example, to send data to other wireless devices or to complete uplink and downlink data transmission between the AP and the STA in the scheduling domain; after the occupation of the AP1 is finished, the AP2 sends indication information to notify that the scheduling domain represented by the AP2 occupies the air interface resource.

In the embodiment of the application, the wireless device receives the indication of the previous wireless device in the occupation sequence to occupy the air interface resource, and indicates the next wireless device in the occupation sequence to occupy the air interface resource when occupation is finished, the wireless devices occupy the air interface resource in a manner of occupying the occupation sequence and sequentially indicating to cooperatively receive and send data, the state of the air interface does not need to be continuously monitored, the air interface resource is occupied through competition, the occupation conflict can be avoided, the uncertainty of the wireless device occupying the air interface resource is reduced, extra waiting time is not needed, and the air interface efficiency and the service experience are improved.

For convenience of understanding, in the embodiment of the present application, taking the sending of the CTS message between the AP1 and the AP2 in fig. 10 as an example, a detailed description is given to a manner in which a wireless device instructs other wireless devices to occupy air interface resources by sending the CTS message.

Referring to fig. 12, an embodiment of the present application provides a schematic diagram of transmission of indication information. The flow of sending the CTS message between AP1 and AP2 is specifically illustrated in fig. 12 and described below.

(1) The AP1 receives a data frame sent by an STA in a scheduling domain represented by the AP1 within a time period when occupying air interface resources, and sends a first CTS message after confirmation by using a Block Ack (BA) mechanism, where the first CTS message carries identification information of the AP2, such as a Basic Service Set Identifier (BSSID) of the AP2, thereby indicating that the AP2 occupies air interface resources.

(2) After receiving the first CTS message of the AP1, the AP2 receives a data frame sent by an STA in a scheduling domain represented by the AP1 within a time of occupying air interface resources, and sends a second CTS message after confirming with a Block Ack (BA) mechanism, where the second CTS message carries identification information of the AP1, such as a Basic Service Set Identifier (BSSID) of the AP1, thereby indicating that the AP1 occupies air interface resources.

(3) After receiving the second CTS message of the AP2, the AP1 triggers an STA in the scheduling domain represented by the STA to send a data frame by using a trigger frame sending mechanism within a time of occupying air interface resources, and sends a third CTS message after confirming by using a Block Ack (BA) mechanism, where the third CTS message carries identification information of the AP2, such as a Basic Service Set Identifier (BSSID) of the AP2, so as to indicate that the AP2 occupies air interface resources.

(4) After receiving the third CTS message of the AP2, the AP2 triggers an STA in the scheduling domain represented by the STA to transmit a data frame by using a trigger frame transmission mechanism within a time period when the AP2 occupies an air interface resource, and transmits a fourth CTS message after confirming by using a Block Ack (BA) mechanism, where the fourth CTS message carries identification information of the AP1, such as a Basic Service Set Identifier (BSSID) of the AP1, so as to indicate that the AP1 occupies the air interface resource.

In addition, to avoid situations such as when the AP1 finishes holding and issues the first CTS message, the air interface resource is preempted by wireless devices other than the AP 2. Optionally, by setting a larger Network Allocation Vector (NAV), it is ensured that other devices cannot preempt air interface resources in a time period corresponding to the NAV, so as to ensure that the AP1 and the AP2 can occupy the air interface resources in turn according to the above procedure.

Further, referring to fig. 13, an embodiment of the present invention provides another scheduling method for air interface resources, where the method is applied to a management device, and the method includes:

step S1301, determining an occupation sequence in which the plurality of wireless devices occupy the air interface resource according to the network topology structures corresponding to the plurality of wireless devices.

Step S1302, an occupation order is transmitted to the plurality of wireless devices.

In the embodiment of the application, the management device firstly determines the occupation sequence of the plurality of wireless devices occupying the air interface resources, and sends the occupation sequence to the plurality of wireless devices, so that the plurality of wireless devices occupy the air interface resources in sequence according to the occupation sequence, the air interface resources are occupied through competition without continuously monitoring the state of the air interface, the occupation conflict can be avoided, the uncertainty of the wireless devices occupying the air interface resources is reduced, extra waiting time is not needed, and the air interface efficiency and the service experience are improved.

In an optional embodiment, the method further comprises: for each of a plurality of wireless devices, performing the following (1) and (2):

(1) determining the time length of the air interface resource occupied by the wireless equipment according to the time length control parameter; the duration control parameter includes one or more of an occupation sequence, service delay requirements of a plurality of wireless devices included in the network topology structure, and service traffic of the wireless devices.

In specific implementation, taking the occupation sequence determined according to the first network topology shown in fig. 6, that is, gateway- > AP1- > AP2- > AP1 as an example: in one round, the gateway and AP2 are only turned to 1 time, while AP1 is turned to 2 times. Determining the occupation time lengths of the gateway, the AP1 and the AP2 according to the occupation sequence, optionally allocating the same occupation time length for the gateway and the AP2, and allocating half of the occupation time length of the AP1 compared with that of the gateway/AP 2; or, if the indication information received by the AP1 is from the gateway, the AP1 may occupy the air interface resource according to the same occupation duration as the gateway; if the indication information received by the AP1 is from the AP2, the AP1 directly sends an indication message to the gateway to notify the gateway to occupy air interface resources.

Optionally, determining the occupied time length according to service delay requirements of a plurality of wireless devices included in the network topology, and if the service delay requirements are high, shortening the time length of the wireless devices occupying the air interface resources each time; if the service delay requirement is low, the time for the wireless equipment to occupy the air interface resource each time can be increased, so that the utilization rate of the air interface is improved, and higher throughput is obtained.

Optionally, considering that service flows of different wireless devices, such as APs, are different, the duration that the AP occupies the air interface resource may also be adjusted according to the service flow of a single AP.

(2) The duration is sent to the wireless device.

In the embodiment of the application, length control parameters such as an occupation sequence of a plurality of wireless devices, service delay requirements of different wireless devices, service flows of different wireless devices, and the like are considered, the lengths of time for occupying air interface resources of different wireless devices are respectively determined for the different wireless devices, and then the determined lengths of time are sent to the corresponding wireless devices. For example, the duration that the first wireless device occupies the air interface resource is determined according to the duration control parameter corresponding to the first wireless device, and the duration is sent to the first wireless device. The time length of the single wireless device occupying the air interface resource is adjusted by combining the service time delay requirements of the current multiple wireless devices of the air interface and the actual service condition of the single wireless device, which is beneficial to improving the air interface efficiency and service experience.

In an optional implementation manner, before performing step S1301, the method further includes:

s1, wireless device distribution information around each of the plurality of wireless devices is acquired.

The wireless device can be an AP, a mechanism for the AP to broadcast beacon (beacon) frames at regular time is specified based on Wi-Fi technical standards, and the AP can acquire distribution information of surrounding APs through the acquired beacon frames, namely, the AP adjacent to the AP is determined; the AP may also carry distribution information of APs around itself in the broadcast beacon frame, and when obtaining the beacon frame broadcast by the AP, the AP adjacent to the AP knows which APs are adjacent to the AP. For example, AP-1 broadcasts beacon frame, and the beacon frame carries distribution information of AP around AP-1; if the AP-2 receives the beacon frame broadcast by the AP-1, it may be determined that the AP-1 is an adjacent AP, and may also determine other APs adjacent to the AP-1.

Based on this, acquiring wireless device distribution information around each of the plurality of wireless devices may be implemented as follows: if the AP is adjacent to the management device, or the AP and the management device are visible, the management device may directly receive the beacon frame of the AP, thereby determining the wireless device distribution information around the AP. If the AP is not visible with the management device, the management device may also determine distribution information of wireless devices around the AP based on the obtained beacon frames broadcast by other APs. For example, in a scenario where AP-1 is adjacent to AP-2, AP-2 is adjacent to AP-3, and AP-3 is adjacent to the management device, but AP-1 and AP-3 are invisible, AP-1 and the management device are invisible, and AP-2 and the management device are invisible, AP-2 obtains a beacon frame broadcast by AP-1, then it can be known that: AP-2 is adjacent to AP-1. The AP-2 carries the information that the AP-2 is adjacent to the AP-1 in the broadcast beacon frame, so that the AP-3 can know that: AP-3 is adjacent to AP-2, and AP-2 is adjacent to AP-1. The AP-3 carries two pieces of information, namely the AP-3 is adjacent to the AP-2 and the AP-2 is adjacent to the AP-1, in a broadcast beacon frame, so that the management equipment can know that: the management device is adjacent to AP-3, AP-3 is adjacent to AP-2, and AP-2 is adjacent to AP-1.

S2, constructing a network topology corresponding to the plurality of wireless devices according to the wireless device distribution information around each wireless device.

In an optional implementation manner, after performing step S1302, the method further includes:

s3, receiving a release signal from a first wireless device, where the release signal is used to instruct the first wireless device to release an air interface resource, and the first wireless device is any one of a plurality of wireless devices;

s4, notifying the second wireless device to occupy the air interface resource according to the occupation sequence, wherein the second wireless device is the first wireless device behind the first wireless device in the occupation sequence.

In specific implementation, the second wireless device may be notified that the second wireless device occupies the air interface resource by sending, to the second wireless device, indication information for indicating that the second wireless device occupies the air interface resource.

In an alternative embodiment, the management device may be a stand-alone wireless device, or may be a wireless device of a plurality of wireless devices; the management device comprises a wireless access point AP.

In addition, in consideration of practical application, some wireless devices may not support cooperative data transmission and reception according to an occupied sequence, so as to ensure that such wireless devices can occupy air interface resources to transmit and receive data. In an optional implementation manner, the management device may determine, according to the determined occupation sequence and occupation durations of the plurality of wireless devices related to the occupation sequence, a period in which the plurality of wireless devices occupy the air interface resource in turn; when the time length occupied by the plurality of wireless devices in turn reaches a first number of periods, indicating that the last wireless device in the occupied sequence stops notifying the next wireless device to occupy the air interface resource after the occupation is finished, and enabling the air interface to be in an idle state within a period of time, so that the wireless devices which do not support cooperative data receiving and sending according to the occupied sequence occupy the air interface resource. The first number may be set according to practical situations, for example, 3, and is not limited herein.
