Description

Wireless access point synchronization cooperation method, device and system Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a wireless access point synchronization cooperation method, device, and system.

Background technique

With the rapid development of Wireless Local Area Network (WLAN) technology, WLANs will be deployed in more complex and denser service scenarios, which makes access points in the unit area (Access Point, referred to as The number of APs has increased significantly. These densely deployed and overlapping coverage APs need to share limited WLAN unlicensed spectrum resources. Therefore, the use of spectrum and the control of interference are no longer independently handled by a single AP, but must be coordinated and coordinated via APs. Come together to complete.

APs can coordinate in the dimensions of frequency, space, time and power, and work collaboratively based on well-coordinated strategies and consensus. In the prior art, if the APs can directly communicate with each other, the direct handshake between the APs is used to coordinate the information and start the cooperation mode. If the APs cannot directly communicate with each other, the station (Station, referred to as STA) is used. The way to transfer to coordinate information and turn on collaboration mode.

When the coordination and cooperation are performed by the prior art, the cooperation request sent by an AP can successfully receive the collaboration request only when the corresponding cooperative AP is in an idle state. However, in a WLAN network, the competition of the wireless channel is usually a carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) mechanism, that is, the APs usually work asynchronously. At any one time, neighboring APs may be in different channel busy states. Therefore, the coordination interaction time between the APs to be coordinated is difficult to determine, the coordination information may not be successfully sent or received, or the channel to be cooperated by the AP to be preempted by the STA or other APs, and the collaboration fails.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The technical solution of the embodiment of the present invention can be applied to a wireless network service scenario, and a plurality of wireless access points (APs) need to share limited spectrum resources. A wireless AP is an access point used in a wireless network to cause a wireless terminal device to enter a wired network. In the following embodiments of the present invention, it is responsible for assisting the coordination and cooperation process of multiple APs, helping the AP to contend for the channel through STAs capable of communicating with multiple coordinated APs, and using the channel after the STA preempts the channel. The rights are simultaneously forwarded to the cooperating AP to trigger a synchronized idle channel, and the cooperating AP can interactively coordinate and cooperate in the channel. The STA may be, for example, a user equipment such as a smartphone, a notebook computer, or a PAD that is connected to an AP.

FIG. 1 is a schematic diagram of an application scenario of a wireless access point synchronization cooperation method according to an embodiment of the present invention. As shown in FIG. 1 , at least two adjacent APs may form one cooperation set, and the overlapping coverage areas of the APs in the cooperation set have at least one STA capable of communicating with the APs in the cooperation set. When the STA in the overlapping coverage area of the cooperation set AP detects that the channel is idle, the node that is in the communication range of the STA has a high probability that it is in an idle state, so that the APs in the collaboration set can simultaneously Obtain channel usage transfer rights and interact and coordinate information within this channel. For example, STA1 can communicate with AP1, AP2, and AP3. AP1 and AP2 can form a collaboration set. AP1 and AP3 can form a collaboration set. AP2 and AP3 can form a collaboration set. AP1, AP2, and AP3 can also form a collaboration set. These collaboration sets are available through STA1 Auxiliary to complete the coordination and collaboration process.

It is worth mentioning that if STA1, STA2, STA3, and STA4 are both capable of communicating with AP1 and AP2, STA1, STA2, STA3, and STA4 can assist the cooperative set composed of AP1 and AP2 for channel contention. Obviously, the greater the number of users (STAs) in the overlapping coverage area of the cooperative set AP, the greater the chance that the AP will gain access to the channel using the transfer rights.

In the following embodiments of the present invention, a cooperative set of AP1 and AP2 will be taken as an example for detailed description. It is apparent that these examples are for illustrative purposes and are not intended to limit the invention.

The embodiments of the present invention are described from the STA side and the AP side respectively, and the cooperation examples of the two are explained at the same time, but this does not mean that the two must be implemented together, but when the two cooperate, a better technology is obtained. effect.

FIG. 2 is a flowchart of a wireless access point synchronization cooperation method according to an embodiment of the present invention. As shown in FIG. 2, the method may include the following steps:

S21, the STA competes for the channel;

S22. The STA sends a first message, where the first message is used to indicate that at least two APs work together using the first channel, where the first channel competes with the STA to obtain a channel for sending the first message.

The execution body of the above steps is STA.

In this embodiment, the application scenario shown in FIG. 1 will be described in detail. As shown in FIG. 1 , the neighboring AP1 and AP2 form a cooperative set, and STA1 to STA4 in the overlapping coverage area of AP1 and AP2 may be users accessing AP1 or AP2, and STA1 may also be a user accessing AP3. . Assuming that the path propagation loss between the AP and the STA is symmetric, if STA1 to STA4 can listen to signals from AP1 and AP2, AP1 and AP2 can also listen to STA1 to STA4 if the transmit power of the AP and STA are equal. If the transmit powers of the AP and the STA are not equal, the STA can determine whether the self-transmitted signal can be received by the AP according to the power difference between the AP and the STA.

Exemplarily, in the application scenario shown in FIG. 1, STA1 to STA4 determine that they can communicate with AP1 and AP2 through judgment, and STA1 to STA4 can assist the cooperative set competition channel composed of AP1 and AP2. STA1 to STA4 also use the CSMA/CA mechanism to detect the busy state of the listening channel. Assuming that STA1 detects that the channel is idle first and then backs off, STA1 obtains the channel usage right at that moment. At this time, the node in the communication range of STA1 has A high probability is in an idle state. After STA1 takes the lead in backoff to obtain the channel usage right, STA1 passes the channel that is contending (first letter) The channel transmits a channel use transfer message (first message) to AP1 and AP2, and transfers the usage right of the first channel to AP1 and AP2. Assuming that AP1 and AP2 both correctly receive the channel usage transfer message from STA1, AP1 and AP2 obtain the channel usage right at the same time, then AP1 and AP2 can work together through the first channel.

It can be understood that there is a possibility that AP1 or AP2 does not correctly receive the channel use transfer message from STA1. At this time, STA1 can judge according to the channel use response message it receives. The response message is, for example, a broadcast message sent by AP1 or AP2, respectively, to inform all STAs that help AP1 and AP2 to contend for the channel and other neighboring stations (including APs and STAs) to work together using the first channel.

In this embodiment, the APs that can communicate with the APs in the cooperation set help the APs in the cooperation set to contend for the channel. After the STAs contend to the channel, the channel usage rights are simultaneously transferred to the APs in the collaboration set. A synchronization time window is triggered on the idle channel, and the AP in the collaboration set can coordinate and coordinate information and perform collaborative work in the synchronization time window. After the STA contends to the channel, the node that is in the communication range of the STA has a high probability that it is in an idle state. In this case, the coordination interaction time between the APs in the collaboration set is predictable. The probability that the information is successfully transmitted or received is greatly improved, so that the feasibility of cooperative work between the APs can be effectively improved, thereby improving the spectrum multiplexing gain in the high-density scenario.

FIG. 3 is a flowchart of another wireless access point synchronization cooperation method according to an embodiment of the present invention. As shown in FIG. 3, the method may include the following steps:

S31. The first AP receives the first message sent by the first STA, where the first message is used to indicate that the first AP uses the first channel and the at least one second AP to work together, and the at least one second AP is in the first STA. Within the communication radius, the first channel competes for the first STA to obtain a channel for transmitting the first message;

S32. The first AP works in cooperation using the first channel and the at least one second AP.

The execution body of the above steps is the first AP.

In this embodiment, the application scenario shown in FIG. 1 will be described in detail. Referring to FIG. 1 , the adjacent AP1 and AP2 form a cooperation set, and STA1 to STA4 in the overlapping coverage area of AP1 and AP2 can communicate with AP1 and AP2. AP1 and AP2 first receive the channel usage transfer message (the first message) sent by STA1, and AP1 and AP2 know that they can cooperate through the channel (first channel) obtained by STA1 competition.

It can be understood that, in order to prevent the first channel from being preempted by other stations (including APs and STAs), AP1 and AP2 may broadcast a response message for the first channel usage right after receiving the first message, and the response message is used to notify all STAs that help AP1 and AP2 compete for channels and neighboring other sites (including APs and STAs) will work together using the first channel.

In this embodiment, after receiving the channel usage transfer message sent by the STA that can communicate with the AP in the cooperation set, the AP in the cooperation set can simultaneously obtain a synchronization time window on the first channel, and synchronize the time window here. Interact and coordinate information and work collaboratively. After receiving the channel usage transfer message sent by the STA, the AP is in an idle state with a high probability that the node in the communication range of the STA is in an idle state. In this case, the coordination interaction time between the APs in the collaboration set is It can be estimated that the probability that the coordination information is successfully transmitted or received is greatly improved, thereby effectively improving the feasibility of inter-AP cooperation, thereby improving the spectrum multiplexing gain in a high-density scenario.

FIG. 4 is a flowchart of still another method for synchronizing and cooperating with a wireless access point according to an embodiment of the present invention. In this embodiment, the technical solution of the present invention is exemplarily illustrated by an implementation manner of an AP and an STA. As shown in FIG. 4, the method may include the following steps:

S41, the STA competes for a channel;

S42, the STA sends a first message, where the first message is used to indicate that at least two APs work together using the first channel, where the first channel competes with the STA to obtain a channel for sending the first message;

S43. At least two APs receive the first message.

S44. At least two APs work together using the first channel.

In this embodiment, the application scenario shown in FIG. 1 will continue to be described in detail, and please refer to FIG. 1 . Adjacent AP1 and AP2 form a cooperative set, and STA1 to STA4 in the overlapping coverage area of AP1 and AP2 may be users accessing AP1 or AP2. Of course, STA1 may also be a user accessing AP3. It is assumed that STA1 to STA4 can communicate with AP1 and AP2, and STA1 to STA4 can assist the cooperative set competition channel composed of AP1 and AP2. STA1 to STA4 also use the CSMA/CA mechanism to detect the busy state of the listening channel. Assuming that STA1 detects that the channel is idle first and then backs off, STA1 obtains the channel usage right at that moment. At this time, the nodes in the communication range of STA1 are both It can be considered to be in an idle state. After STA1 takes the lead to back off and obtains the channel usage right, it simultaneously transmits a channel use transfer message (first message) to AP1 and AP2, and hands over the competing channel (first channel) usage right to AP1 and AP2. Both AP1 and AP2 correctly receive the channel usage transfer message from STA1, and AP1 and AP2 obtain the channel usage right at the same time, then AP1 and AP2 can work together through the channel (first channel) that STA1 contends.

It can be understood that, in order to prevent the first channel from being preempted by other STAs and other APs, AP1 and AP2 may broadcast a response message for the first channel usage right after receiving the first message, and the response message is used to notify all the help AP1. STAs that compete with AP2 for the channel and other neighboring stations (including APs and STAs) will use the first channel to work together.

Of course, there is a possibility that AP1 or AP2 does not correctly receive the channel usage transfer message from STA1. At this time, STA1 can judge according to the response message it receives. If STA1 does not receive the response message sent by AP1 and AP2, or only receives the response message sent by one of AP1 and AP2, STA1 continues to contend for the channel.

It can be understood that, on the one hand, after STA1 sends the first message of the first message, it can wait for a fixed time interval. If a response message sent by any AP is still not received after a fixed time interval, STA1 can determine. AP1 and AP2 did not successfully receive the first message and continue to perform channel contention and resend the first message. On the other hand, STA1 may not receive the response message sent by AP1 and AP2 at the same time. After STA1 receives the response message sent by one of AP1 and AP2, STA1 may wait for a fixed time interval, if after a fixed time interval. If the response message sent by another AP is still not received, STA1 may determine that another AP has not successfully received the first message first message, and continues to perform channel contention and resend the first message.

When AP1 and AP2 are successfully coordinated, they can start to work together in accordance with the coordinated collaborative work rules. It should be noted that the so-called collaborative work may be the downlink data transmission of the AP to the STA, or the uplink data transmission of the STA to the AP. The specific collaborative work process is not within the scope of the present invention. If the coordination between AP1 and AP2 fails, it returns to the non-cooperative mode.

In this embodiment, the cooperation between AP1 and AP2 can be triggered by the STA side or by the AP side.

If AP1 and AP2 work together, the STA side triggers, that is, one or more STAs in STA1 to STA4 spontaneously assist AP1 and AP2 in channel contention. The STA that first competes to the channel transfers the channel usage right to AP1 and AP2 requires AP1 and AP2 to work together.

If AP1 and AP2 work together, the AP side triggers, that is, one or more STAs in STA1 to STA4 receive the instruction to request the first message. AP1 and AP2 perform channel competition, and the indication information is used to indicate that the STA contends for the channel for AP1 and AP2. Exemplarily, since STA1 to STA4 can communicate with AP1 and AP2, AP1 or AP2 may send indication information to one or more STAs of STA1 to STA4; or AP1 and AP2 both to one or more of STA1 to STA4. The STA sends the indication information; if the STA1 can communicate with the AP1 to the AP3 at the same time, the AP3 may also send an indication message to the STA1, instructing the STA1 to assist the AP1 and the AP2 to contend for the channel.

Further, the indication information of the requesting the first message may include the identifiers of the AP1 and the AP2, and the identifiers of the AP1 and the AP2 are, for example, a basic service set identifier (BSSID). After receiving the indication information including the BSSIDs of AP1 and AP2, the STA can uniquely determine AP1 and AP2 according to the BSSIDs of AP1 and AP2.

As another optional implementation manner, the indication information requesting the first message may further include an identifier (ID) of the cooperation set composed of AP1 and AP2. It can be understood that the WLAN network may further include a wireless controller (Access Controller, AC for short) for managing all the APs, and the AC may allocate a corresponding collaboration set ID for the cooperation set composed of two or more APs. That is, each collaboration set ID has a unique correspondence with the ID of the AP in the collaboration set. Exemplarily, the AC allocates a collaboration set ID of S1 for the cooperation set composed of AP1 and AP2, and the STA that receives the indication information of the S1 can be uniquely determined according to the correspondence between the S1 and the collaboration set ID and the ID of the AP included in the collaboration set. Out of AP1 and AP2. Optionally, in the absence of AC, AP1 and AP2 can also negotiate to share the same collaboration set ID.

As still another optional implementation manner, the indication information requesting the first message may further include a collaboration set ID. After the STA receives the ID indication information including the cooperation set, the STA may only contend for the cooperation set corresponding to the ID according to the indication information, and does not need to determine which APs are included in the cooperation set. At this time, the STA that successfully contends to the channel may add the cooperation set ID in the indication information to the first message as the identifier of the first message, and broadcast the first message. The AP that receives the first message may determine whether it belongs to the collaboration set according to the identifier of the first message, accept the first message if it belongs, and ignore the first message if it does not belong. It can be understood that the AP can decide which STAs to send indication information to.

In this embodiment, the STA may determine, according to the signal strength of the monitored AP, an AP to send an access request message, and the AP may send an access response message to the corresponding STA. The STA can also determine which APs are in the air according to the transmit power of the AP and the AP that can be monitored. Within the maximum effective communication radius.

Preferably, the STA can report to the APs it accesses the set of APs that can communicate with each other, that is, all APs within the communication radius of the STA. The AP can determine which APs can work with each other according to the set of communication APs reported by the STA. Obviously, the AP can also determine which STAs can be requested to assist channel competition when it cooperates with certain APs according to the STAs of the communication AP set to which it reports. Optionally, the AP may also send the collaboration set identifier set to the STA according to the communication AP set reported by the STA. Obviously, the AP may determine whether an STA can effectively serve a certain cooperation set according to the communication AP set reported by the STA. At this time, the AP may decide to send the ID indication information including the cooperation set to the STA that can effectively serve a certain cooperation set.

Optionally, the STA may directly include the set of the communication APs in the access request message and report the AP to the AP. The AP may also include the cooperation set identifier set in the access response message and send it to the STA. It is worth mentioning that the access response message may even directly include indication information of the first message requesting for a certain cooperation set.

Exemplarily, STA1 can listen to signals from AP1 to AP3, and the received signal strength from AP1 is higher than the received signal strength from AP2 and AP3, and STA1 decides to send an access request to AP1. If STA1 can be received by AP2 and AP3 by judging that the self signal is obtained, STA1 reports the information of AP2 and AP3 to AP1, for example, the BSSIDs of AP2 and AP3. Obviously, the access request message sent by STA1 to AP1 may directly include the BSSIDs of AP2 and AP3.

AP1 then knows that STA1 is in the overlapping coverage area of AP1, AP2 and AP3, and the signal of STA1 can be simultaneously received by AP1, AP2 and AP3. Correspondingly, AP1 can set a collaboration set composed of AP1 and AP2, a collaboration set composed of AP1 and AP3, a collaboration set composed of AP2 and AP3, and a collaboration set identifier corresponding to the collaboration set composed of AP1, AP2, and AP3 (such as S1 and S2). S3, S4) are sent to STA1. Obviously, these collaboration set identifiers can be directly included in the access response message and sent to STA1. Moreover, the AP1 may also carry indication information requesting the STA1 to assist the AP1 and the AP2 to perform channel competition in the access response message.

It can be understood that since the STA is usually a mobile user equipment, the STA location will constantly change. As the location of the STA changes, the set of APs that the STA can communicate with will also change. As a preferred implementation manner, the STA can actively report the AP set that it can communicate to the AP that it accesses at any time after the network access. Alternatively, the AP may also initiate a report of the communication AP set report of the STA to the STA at any time after the STA accesses the network, and the STA reports the report to the AP after receiving the report request. Communication AP collection.

As another optional implementation manner, the STA may report the communication AP set to the AP that is accessed by the STA, and may also report its own communication AP set to some or all of the APs in the communication AP set. Similarly, the AP may send a communication AP set report request to some or all STAs within the AP communication range, in addition to sending a communication AP set report request to the STA that accesses itself.

It can also be understood that the AP can send the indication information to a certain control/management frame (such as a Beacon frame), or a new definition, in addition to the indication information for requesting the first message to the STA that accesses itself. The Medium Access Control (MAC) layer controls/manages the frame and broadcasts it to the STAs in the AP communication range.

Further, the indication information of the request first message sent by the AP broadcast may include an ID of a plurality of APs indicating cooperation, or a collaboration set ID corresponding to a collaboration set composed of multiple APs.

Generally, for the indication information of the request first message included in the access response message, only the corresponding STA receives the indication information and directly performs channel contention. The indication information contained in the control/management frame is generally broadcast information, and all STAs within the control/management frame reception range can receive the indication information. The STA that has received the broadcast indication information first determines the AP to be coordinated, and then performs channel contention after determining that it can communicate with each of the APs to be coordinated.

Optionally, the indication information of the request first message sent by the AP broadcast may further include an identifier of the STA that is expected to participate in channel competition. The STA that receives the broadcast indication information first determines whether it is an AP designated by the AP to participate in channel competition. If so, the APs to be coordinated are further determined, and then channel competition is performed after determining that they can communicate with each of the APs to be coordinated.

Another possibility is that the AP can determine that a certain STA can effectively serve certain cooperation sets according to the communication AP set reported by the STA, and the AP directly specifies the STAs that are expected to participate in channel competition. The indication information of the first message requesting the broadcast may include the identifier of the STA that is expected to participate in the channel competition. At this time, only the corresponding STA may receive the broadcast indication information and perform channel competition directly, and the STA that successfully contends to the channel may indicate The collaboration set ID in the information is added to the first message as an identifier of the first message, and the first message is broadcasted. Of course, the AP may also directly send an indication message requesting the first message to the STA that desires to participate in channel competition.

It can be understood that multiple APs need interactive coordination information, that is, specific collaborative work rules, before performing collaborative work. In this embodiment, the following optional implementation manners are specifically provided to interact Coordination information:

As a first optional implementation manner, the collaborative work rule may be included in the indication information for requesting the first message, and the STA determines, according to the indication information, that the participant can participate in the channel competition, and then cooperates after successfully competing to the first channel. The rule is carried in the first message and sent to the AP in the collaboration set. Or the STA may temporarily store the cooperative working rule, wait for the AP in the cooperation set to send the response message of the first channel usage right, and immediately cooperate with the STA after receiving the response message of the first channel usage right sent by all the APs in the cooperation set. The rule is sent to the AP in the collaboration set. In this way, the overhead of coordinated interaction of the APs in the collaboration set through the first channel can be saved.

It should be noted that, if multiple APs in the collaboration set send the indication information requesting the first message to the STA, and the indication information includes the collaborative work rule, the AP may also carry its own priority information in the indication. Information. The STA may send the coordinated working rule in the indication information sent by the AP with the highest priority to the other low-priority AP according to the priority of the AP that sends the indication information.

As a second optional implementation manner, the AP to be coordinated may exchange the cooperative working rule through the first channel after obtaining the usage right of the first channel that the STA competes. In order to prevent multiple APs in the AP to be coordinated from simultaneously initiating the interaction request, the following optional methods may be used for coordination:

a) The APs participating in the collaboration may be set with different priorities. The high-priority APs have the coordinated initiative, and the APs with the highest priority in the collaboration set send the coordinated work rules to other APs in the collaboration set through the first channel.

If the STA that sends the first message is currently in the AP in the collaboration set, the AP that is sent by the STA that sends the first message has the coordinated initiative, and the AP accessed by the STA that sends the first message The collaborative work rule is sent to other APs in the collaboration set through the first channel.

c) The STA may also inform the AP in the cooperation set through the first message sent by the STA, and participate in the current channel competition is the indication information of which AP is received. For example, after STA1 first contends to the channel, the AP1 and AP2 may be notified by the first message. When participating in this channel competition is the indication information of the first message of the request of AP1, AP1 has the coordinated initiative.

It can be understood that in this embodiment, an appropriate coordination method can be selected according to different situations.

Further, this embodiment also schematically illustrates the technical solution of the present invention by using a frame structure of the first message.

FIG. 5 is a schematic diagram of a frame structure of a first message sent by a STA. Referring to FIG. 5, an FC (Frame Control) may include a definition of a frame type, and a type definition may indicate the role and meaning of the frame. The Coordination Group ID refers to the collaboration set identifier, or may list the identifiers of all APs in the collaboration set, that is, the collaboration AP list. The TA is the address of the STA that sends the first message. The triggering AP ID (Trigger AP ID) refers to the address of the AP that triggers the current channel competition. Obviously, both the TA and Trigger AP IDs are optional, while other unillustrated cells have the same meaning as the current standard. The FCS is a Frame Check Sequence.

FIG. 6 is a schematic diagram of a frame structure of a first message sent by another STA. The frame structure of the first message shown in FIG. 5 may further include Coordination Information, and the specific collaborative work rule may be It is included in the indication information that the AP that requests the first message to send to the STA, so when the STA sends the first message, the collaborative work rule can also be included. The collaborative work rules may specifically include information such as the coordinated transmission technology, mechanism, configuration parameters, and synchronization duration of the coordinated transmission.

It should be noted that the frame structure of the first message shown in FIG. 5 and FIG. 6 is only a possible MAC frame structure of the first message, which is mainly indicated by the frame type indication in the FC in the MAC frame header. The MAC frame is distinguished. Correspondingly, in order to let the AP receiving the first message know the frame type earlier, the corresponding prompt information may be added in the physical layer header of the MAC frame.

Exemplarily, the prompt information may be added in a signaling domain in a physical layer header of a data packet corresponding to a Physical Layer Convergence Procedure (PLCP) Data Unit (PLCP) Data Unit (PPDU). A 1-bit indicator bit may be added to indicate that the data packet contains MAC frame information for the first channel usage right transfer; the cooperation set identifier may also be directly included so that the AP not in the cooperation set can ignore the reception of the subsequent data packet. FIG. 7 is a schematic diagram of a data packet structure of a first message sent by a STA. As shown in FIG. 7, the PPDU data may carry MAC layer information as shown in FIG. 5 and FIG. 6. SIG (Signature) is the signaling domain in the physical layer header, and can be added with prompt information. Obviously, if the cooperation set ID has been carried in the physical layer SIG domain, the PPDU data does not need to indicate the cooperation set ID when carrying the MAC frame shown in FIG. 6.

The wireless access point synchronization cooperation method provided in this embodiment helps the APs in the cooperation set to contend for the channel through the STAs that can communicate with the APs in the cooperation set. After the STAs contend to the channel, the channel usage rights are simultaneously transferred to the collaboration set. AP, in order to trigger a synchronization on the idle channel In the time window, the APs in the collaboration set can coordinate and coordinate information and work collaboratively within this time window. After the STA contends to the channel, the node that is in the communication range of the STA has a high probability that it is in an idle state. In this case, the coordination interaction time between the APs in the collaboration set is predictable. The probability that the information is successfully transmitted or received is greatly improved, so that the feasibility of cooperative work between the APs can be effectively improved, thereby improving the spectrum multiplexing gain in the high-density scenario.
