First, a description is given of a related art related to an embodiment of the present application.
Multilink Operation (MLO):
Briefly, MLO is a wireless fidelity (Wireless Fidelity, wi-Fi) technology that establishes multiple links (links) simultaneously between a Station (STA) and an Access Point (AP) for communication.
Fig. 1 shows a communication schematic diagram of a wireless communication Device, including a Multi-Link Device (MLD) and a legacy wireless Device. MLD is a wireless device 110 supporting MLO technology and a wireless device 120 supporting MLO technology, and 3 wireless links are established between the wireless device 110 and the wireless device 120. Legacy wireless devices, i.e., wireless device 130 that does not support MLO technology and wireless device 140 that does not support MLO technology. Compared with the traditional wireless device which does not support the MLO technology, the wireless device which supports the MLO technology has the following two advantages:
(1) Data can be transmitted and/or received simultaneously on three frequency bands (bands) of 2.4GHz, 5GHz and 6GHz between two devices supporting the MLO technology. Thus, a wireless device supporting MLO technology can improve throughput.
(2) Multiple links operating in three different frequency bands can compete for medium access rights simultaneously. After any link acquires the medium access right, the data transmission can be started. The MLO enabled wireless device can acquire more transmission opportunities than in the conventional manner of medium access contention on only one frequency band. Wireless devices supporting MLO techniques can significantly reduce the delay of data transmission.
However, the above MLO technique also has the following two disadvantages:
(1) The wireless device supporting the MLO technology communicates simultaneously due to the existence of a plurality of links, and each link operates corresponding to a complete set of physical layer (PhysicalLayer, PHY) and Radio Frequency (RF). If the 3 links are always in Active state, the power consumption of the Wi-Fi chip will increase significantly. Although each link has its own power saving strategy, since the power saving strategies on different links are independent, optimal power saving effects cannot be achieved for the wireless device.
For example, when the wireless device 110 has data to send to the peer wireless device 120, the MLO technology may attempt to acquire the medium access right on the channel where the 3 links are located at the same time, and as long as there is one link that acquires the medium access right first, the data packet may be sent from the link that acquires the medium access right first. This approach, while reducing latency, also results in a significant increase in power consumption. In Wi-Fi practical application, the requirements on delay are high except for some scenes of games or voice calls, and most of the rest scenes are not very concerned about reducing delay, and more concerned about reducing power consumption is the fact.
(2) In the link established by the wireless device supporting the MLO technology, if an abnormality occurs in a certain link, for example, the environment where the link is located is very noisy, or the hardware of the link itself has a problem, if all 3 links are still used for communication, not only no gain will be generated, but also the communication of the other two normal links will be interfered because of the medium access control protocol data unit aggregation (Aggregate Media Access Control Protocol Data Unit, AMPDU) hole caused by the abnormal link.
Therefore, the multi-link management method is beneficial to reducing the power consumption of wireless equipment and avoiding interference between links.
Fig. 2 shows a schematic diagram of a Wi-Fi system provided by an exemplary embodiment of the present application. The Wi-Fi system includes a terminal device and a terminal device, or a terminal device and a network device, or an AP and an STA, which is not limited in this application.

The AP is equivalent to a bridge connecting a wired network and a wireless network, and mainly serves to connect each wireless network client together and then access the wireless network to the ethernet. The AP device may be a terminal device or a network device with a Wi-Fi chip.

Since the corresponding management operation is performed not only by considering the operation parameters of the at least one link itself but also by considering the operation parameters of at least two links, the management operation is more beneficial to the first MLD for saving the power consumption of the first MLD and avoiding inter-link interference.
Fig. 4 is a flow chart illustrating a method of multilink management according to some exemplary embodiments of the present application. The method is schematically illustrated as being performed by the first MLD. The method comprises at least part of the following steps:
step 420: starting a timer;

The first timing condition is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the timer is an aperiodic timer, the first MLD periodically performs a management operation on at least one link based on the operating parameters of at least two links. The timer is started based on the timing indication information, or the timer is started in a case where the second timing condition is satisfied.

Step 441: executing a first management operation on at least one link under the condition that the working parameters of at least two links meet a first condition;
the first management operation includes activating a link. The first condition is a condition related to the traffic demand exceeding the current link capability.
The traffic requirement refers to a requirement of traffic currently carried by the link and/or a requirement of traffic expected to be carried by the link. The business requirements include, but are not limited to, at least one of the following: delay, bandwidth, retransmission rate, transmission rate, packet loss rate, reliability, transmission order, quality of service (Quality of Service, qoS).

Low latency services include gaming services, audio video services (such as voice call services, video call services, live services, etc.), or other services where the user plane delay corresponds to a millisecond delay. Specifically, for game services, the user plane delay should not be higher than 60ms, preferably lower than 10ms; for voice call traffic, the user plane delay should not be higher than 150ms. Non-low latency services include services that browse web pages/advertisements, download movies, view video, or other user plane delays that do not necessarily correspond to millisecond delays.
Step 443: executing a second management operation on the at least one link if the operating parameters of the at least two links satisfy a second condition;

instruct the second MLD to transmit data during a second period of time;
instruct the second MLD not to transmit data for a second period of time;
Informing the second MLD of the data transmission by the first MLD;
informing the second MLD that the first MLD is not transmitting data;
informing the second MLD of the data transmission by the first MLD during the second time period;
informing the second MLD that the first MLD does not transmit data for the second period of time.
In some embodiments, the effective time of transmitting the indication information is the second time period, or the effective time of transmitting the indication information is the time period between the present indication information and the next nearest indication information.
In some embodiments, if the transmission instruction information is used for "instructing the second MLD to perform data transmission", the effective time of the transmission instruction information is a time period between the present transmission instruction information and the next latest transmission instruction information used for "instructing the second MLD not to perform data transmission". Similarly, if the transmission instruction information is used for "notifying the second MLD of data transmission not performed by the first MLD", the effective time of the transmission instruction information is a time period between the present transmission instruction information and the next latest transmission instruction information for "notifying the second MLD of data transmission performed by the first MLD". The effective time of the transmission indication information of other contents refers to the foregoing contents, and will not be described in detail.
In summary, the method provided in the present application manages at least one link established by the first MLD during the timing process of the timer. Since the management operation in the corresponding second period is performed not only considering the operation parameters of the at least one link itself in the first period, but also considering the operation parameters of at least two links in the first period, the management operation is more beneficial to the first MLD for saving the power consumption of the first MLD and avoiding inter-link interference. And, since the timer may be started periodically, or half-periodically, or non-periodically, the link management of the first MLD has a higher flexibility.
Fig. 6 is a flow chart illustrating a method of multilink management according to some exemplary embodiments of the present application. Taking the method performed by the first MLD, the first MLD and the second MLD establish three links as an example for illustration. The method comprises at least part of the following steps:
step 601: establishing a connection with a second MLD;
the first MLD is an AP210 as shown in fig. 2 or a STA220 as shown in fig. 2.
Three links are established between the first MLD and the second MLD. The second MLD is the STA220 shown in fig. 2 or the AP210 shown in fig. 2.
In some embodiments, the link states of the three links are set to default states after a connection is established between the first MLD and the second MLD. The default state refers to that all three links are in an activated state, or that one link is in a deactivated state, or that two links are in a deactivated state.
The link in the active state is called an active link (active link), and the hardware of the active link is in a power up state, and the state supports the receiving or sending of data; the link in the deactivated state is simply called an inactive link (inactive link), and the hardware of the inactive link is in a power-down (PowerDown) state, which does not support reception or transmission of data. The power consumption of the active link is higher than the power consumption of the inactive link.
Step 602: starting a timer;
if the timer is a periodic timer, the current start is a periodic start. The period value is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the timer is a half-period timer, the current start is a periodic start, or the current start is a start when the first timing condition is satisfied, or the current start is a start based on timing indication information. Wherein the period value is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The timing indication information is transmitted by the first MLD or the second MLD. The first timing condition is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the timer is an aperiodic timer, the current start is a start when the second timing condition is satisfied, or the current start is a start based on timing instruction information. Wherein the timing indication information is transmitted by the first MLD or the second MLD. The second timing condition is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
Since the first MLD counts the operating parameters of the three links that have been established in the step after the start of the timer, the start of the timer may also be considered as the start of the current counting period. The current statistical period, i.e., the first period of time, is denoted as T1 in this embodiment.
Step 603: judging whether the current service is a low-delay service or not;
the working parameters of the three links counted in the step are the service types of the bearing service. The service types of the bearer service include: the type of service of the current bearer service and/or the type of service of the expected bearer service.
If the traffic type of the current traffic is low delay traffic, step 604 is entered.
If the service type of the current service is not a low delay service, step 605 is entered.
Step 604: executing a first management operation;
if the service type of the current service is a low-delay service, the first condition is satisfied, and a first management operation is performed on at least one link, where the first management operation includes activating the link.
In some embodiments, the link states of the three links over the first period of time are counted, the link states including an active state, or a deactivated state.
If there is a link in a deactivated state among the three links, i.e., there is a deactivated link among the three links, a first management operation is performed on the deactivated link, the first management operation including activating the link.
If there are no links in the deactivated state among the three links, i.e., all of the three links are active links, a first management operation is performed on the active links, the first management operation including no operation.
Step 605: counting the link state of the link in a first time period;
wherein the link state includes link information including at least one of:
the packet transmission duration T2 on the link;

t3 refers to the duration that the medium of the channel on which the link is located is in an idle state.
Packet transfer size B1 on link;
b1 is the sum of the size of the received data packet and the size of the transmitted data packet. The size of the transmission packet is the sum of the size of the transmission packet in the case of successful transmission of the packet and the size of the transmission packet in the case of failed transmission of the packet.
The retransmission packet duty cycle R1 on the link;
r1 is the ratio of the number of retransmission packets in the transmission packet to the total transmission packet number.
Link idle time duty cycle P1;
p1 is the duty cycle of the channel idle period during the first period, i.e. p1=t3/T1.
Link free bandwidth Bs.
Bs is the product of the ratio of the packet transmission size to the packet transmission duration and the channel idle duration, i.e., bs= (B1/T2) ×t3.
In some embodiments, the link states of the three links over a first period of time are counted; or, counting the link states of the active links in the first time period in the three links.
Step 606: calculating the link state of the link in a second time period;
based on the link state of the link counted in step 605 during the first period, the link state of the link during the second period is calculated. In some embodiments, link states of the three links within the second time are calculated; or calculating to obtain the link state of the active link in the second time period in the three links; or calculating the link state of the deactivated link in the second time period in the three links.
The link state includes an active state, or a deactivated state.
Step 607: performing a management operation;
and performing a management operation on the link based on the link state of the link calculated in step 606 for the second period of time. The management operations include a first management operation and/or a second management operation. The first management operation includes activating a link and/or no operation, and the second management operation includes deactivating a link and/or no operation.
If there is a first link among the three links based on step 605 and step 606, the aforementioned first condition is satisfied, and a first management operation is performed on at least one link. If the at least one link is a deactivated link, the first management operation includes activating the link. If the at least one link is an active link, the first management operation includes no operation.
Wherein the first link is a link in an active state and the link idle time duty cycle P1 is smaller than a first threshold. The first threshold is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the traffic type of the bearer traffic is non-low latency traffic and/or there is a second link among the three links and/or there is a third link among the three links based on steps 605 and 606, the aforementioned second condition is satisfied and a second management operation is performed on at least one link. If the at least one link is an active link, the second management operation includes deactivating the link and/or no operation. If the at least one link is a deactivated link, the second management operation includes no operation.
The second link is a link in an active state and the link idle time duty ratio P1 is greater than a second threshold value, the third link is a link in an active state and the data packet transmission size B1 is smaller than the link idle bandwidth Bs of the fourth link, and the fourth link is a link in an active state.
It should be understood that the information "first link", "second link", "third link", "fourth link", and the like in this application are used to distinguish links that satisfy different conditions or are in different states, and do not mean that there are actually necessarily or only four links. For example, a link that is actually present may be both the first link and the fourth link, three links that are actually present may be both the fourth link, and so on.
Step 608: transmitting transmission indication information;
wherein the transmission indication information is used for at least one of:
instruct the second MLD to perform data transmission;
instruct the second MLD not to transmit data;
instruct the second MLD to transmit data during a second period of time;
instruct the second MLD not to transmit data for a second period of time;
informing the second MLD of the data transmission by the first MLD;
informing the second MLD that the first MLD is not transmitting data;
Informing the second MLD of the data transmission by the first MLD during the second time period;
informing the second MLD that the first MLD does not transmit data for the second period of time.
In some embodiments, the effective time of the indication information is the second time period, or the effective time of the indication information is the time period between the current indication information and the next nearest indication information.
In some embodiments, if the indication information is used for "indicating that the second MLD is transmitting data", the effective time of the indication information is a time period between the current indication information and the next latest indication information used for "indicating that the second MLD is not transmitting data". Similarly, if the indication information is used for "notifying the second MLD of the failure of the data transmission by the first MLD", the effective time of the indication information is a time period between the current indication information and the next latest indication information for "notifying the second MLD of the failure of the data transmission by the first MLD". The effective time of the indication information of other contents refers to the foregoing contents, and will not be described in detail.
In some embodiments, the transmission indication information is indicated by a power management (PowerManagement, PM) field. When the PM field takes the first value, the PM field is used to instruct the second MLD to perform data transmission, or instruct the second MLD to perform data transmission in the second time period, or notify the second MLD of the data transmission performed by the first MLD in the second time period. In some embodiments, the first value is "0". When the PM field takes the second value, it is used to instruct the second MLD not to transmit data, instruct the second MLD not to transmit data in the second time period, notify the second MLD that the first MLD does not transmit data, or notify the second MLD that the first MLD does not transmit data in the second time period. In some embodiments, the second value is "1".
In some embodiments, the PM field is carried in a data frame, and/or a management frame, and/or a control frame.
In some embodiments, the PM field occupies 1 bit (bit), and the PM field is included in the frame control field.
Step 609: the timer is turned off.
If the timer is a periodic timer, the closing is periodic. The period value is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the timer is a half-cycle timer, the current shutdown is a periodic shutdown, or the current shutdown is a shutdown when the third timing condition is satisfied, or the current shutdown is a shutdown based on timing instruction information. Wherein the period value is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The timing indication information is transmitted by the first MLD or the second MLD. The third timing condition is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
If the timer is an aperiodic timer, the current shutdown is a shutdown when the fourth timing condition is satisfied, or the current shutdown is a shutdown based on timing instruction information. Wherein the timing indication information is transmitted by the first MLD or the second MLD. The fourth timing condition is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
In some embodiments, closing the timer means the end of the current statistics period, i.e. the end of the first period of time.
In some embodiments, closing the timer means the start of the next statistics period. If the next statistical period is a second period of time, step 609 means the beginning of the second period of time. If the next statistical period is a third time period, step 609 means the start of the third time period.
If the management operation is performed on at least one link based again on the operation parameters of at least two links while maintaining the current three link connection, steps 602 to 609 are repeated. If the management operation is performed on at least one link based on the operation parameters of at least two links again in the case that the connection condition of the current three links is changed, steps 601 to 609 are repeated.
In summary, the method provided in the present application manages at least one link established by the first MLD during the timing process of the timer. Since the management operation in the corresponding second period is performed not only considering the operation parameters of the at least one link itself in the first period, but also considering the operation parameters of at least two links in the first period, the management operation is more beneficial to the first MLD for saving the power consumption of the first MLD and avoiding inter-link interference. And, since the timer may be started periodically, or half-periodically, or non-periodically, the link management of the first MLD has a higher flexibility.
In some embodiments, calculating the link state of the link during the second period in step 606 may be divided into at least three cases as shown in fig. 7, taking into account different cases. Taking the current establishment of three links between the first MLD and the second MLD as an example, schematic description will be made.
Step 6062: the number of active links is determined.
Case one: the links currently established are all active links.
That is, the number of active links among the three links currently established is 3, and the three links are distinguished by L0, L1, and L2.
If the link idle time duty cycle P1 of all active links is greater than the threshold M1, the three links are ordered by the retransmission packet duty cycle R1, and the link with the largest retransmission packet duty cycle R1 is the weak link (WeakLink). Let L0 be the link with the largest retransmission packet ratio R1 among the three links, i.e., let L0 be the weak link.
If the transmission size B1 of the data packet on L0 is smaller than the sum of the link idle bandwidths Bs of the other two links (L1 and L2), the link state of L0 in the second time period is calculated to be in a deactivated state, and the link states of L1 and L2 in the second time period are still in an activated state. Then the management operation performed on L0 is to deactivate the link and the management operations performed on L1 and L2 are no operations.
If the transmission size B1 of the data packet on the L0 is not less than the sum of the link free bandwidths Bs of the other two links, that is, the transmission size B1 of the data packet on the L0 is greater than or equal to the sum of the link free bandwidths Bs of the other two links, the link states of L0, L1 and L2 in the second time period are still in the active state. Then, the management operation performed on L0, L1, and L2 is no operation.
If the link idle time duty ratios P1 of the three links are not all greater than the threshold M2, that is, if the link idle time duty ratio P1 of the link existing in the three links is less than or equal to the threshold M2, the link states of L0, L1 and L2 in the second period of time are still calculated to be active states. Then, the management operation performed on L0, L1, and L2 is no operation.
Wherein the threshold M1 is equal to or different from the threshold M2. The threshold M1 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The threshold M2 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
And a second case: at least two active links exist in the currently established links, but not all are active links.
That is, the number of active links in the three links currently established is 2, and it is assumed that the two active links are L0 and L1, and L2 is the inactive link.
If there are two active links with a link idle time duty ratio P1 greater than the threshold M3, for example, the link idle time duty ratio P1 of L1 is greater than the threshold M3, the link state of L1 in the second period is calculated to be in a deactivated state, the link state of L0 in the second period is still in an activated state, and the link state of L2 in the second period is still in a deactivated state. Then the management operation performed on L1 is to deactivate the link and the management operations performed on L0 and L2 are no operations.
If the link idle time duty cycle P1 of both active links is less than or equal to the threshold M4, the two active links are ordered by the retransmission packet duty cycle R1, and the link with the largest retransmission packet duty cycle R1 is the weak link (WeakLink). Let L1 be the link with the largest retransmission packet ratio R1 among the two active links, i.e. let L1 be the weak link.
If the transmission size B1 of the data packet on the L1 is smaller than or equal to the link idle bandwidth Bs of the other active link L0, the link state of the L1 in the second period is calculated to be in the inactive state, the link state of the L0 in the second period is still in the active state, and the link state of the L2 in the second period is still in the inactive state. Then the management operation performed on L1 is to deactivate the link and the management operations performed on L0 and L2 are no operations.
If the transmission size B1 of the data packet on the L1 is greater than the link idle bandwidth Bs of the other active link L0, the link state of the L1 in the second period is still in an active state, the link state of the L0 in the second period is still in an active state, and the link state of the L2 in the second period is still in a deactivated state. Then, the management operation performed on L0, L1, and L2 is no operation.
Wherein the threshold M3 is equal to or different from the threshold M4. The threshold M3 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The threshold M4 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
And a third case: there is an active link in the currently established links.
That is, the number of active links among the three links currently established is 1, and it is assumed that this active link is L0, and L1 and L2 are inactive links.
Mode one:
if the link idle time duty ratio P1 of the active link is smaller than the threshold value M5, the link state of L0 in the second time period is still the active state, and the link states of L1 and L2 in the second time period are the active states. Then the management operation performed on L0 is no operation and the management operations performed on L1 and L2 are active links.
If the link idle time duty ratio P1 of the active link is not less than the threshold M6, that is, if the link idle time duty ratio P1 of the active link is greater than or equal to the threshold M6, the link state of L0 in the second period is calculated to be still in the active state, and the link states of L1 and L2 in the second period are still in the inactive state. Then, the management operation performed on L0, L1, and L2 is no operation.
Wherein the threshold M5 is equal to or different from the threshold M6. The threshold M5 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The threshold M6 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.
Mode two:
if the link idle time duty ratio P1 of the active link is smaller than the threshold value M7, the link state of L0 in the second period is still the active state, and the link state of L1 or L2 in the second period is the active state. If the link state of L1 is active during the second period of time, then the link state of L2 remains inactive during the second period of time, then the management operations performed on L0 and L2 are no operations, and the management operations performed on L1 are active links. If the link state of L2 is active during the second period of time, then the link state of L1 is still inactive during the second period of time, then the management operations performed on L0 and L1 are no operations, and the management operations performed on L2 are active links.
If the link idle time duty ratio P1 of the active link is smaller than the threshold value M8, the link state of L0 in the second time period is still the active state, and the link states of L1 and L2 in the second time period are the active states. Then the management operation performed on L0 is no operation and the management operations performed on L1 and L2 are active links.
If the link idle time duty ratio P1 of the active link is greater than or equal to the threshold value M7, the link state of L0 in the second period of time is calculated to be still in an active state, and the link states of L1 and L2 in the second period of time are still in an inactive state. Then, the management operation performed on L0, L1, and L2 is no operation.
Wherein the threshold M7 is greater than the threshold M8. The threshold M7 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD. The threshold M8 is predefined, or preconfigured, or autonomously decided by the first MLD, or indicated by the second MLD.

In some embodiments, if the indication information is used for "indicating that the second MLD is transmitting data", the effective time of the indication information is a time period between the current indication information and the next latest indication information used for "indicating that the second MLD is not transmitting data". Similarly, if the indication information is used for "notifying the second MLD of the failure of the data transmission by the first MLD", the effective time of the indication information is a time period between the current indication information and the next latest indication information for "notifying the second MLD of the failure of the data transmission by the first MLD".

If the transmission instruction information is used for instructing the second MLD to perform data transmission, the second MLD sends data to the first MLD after receiving the transmission instruction information.
If the transmission indication information is used for indicating that the second MLD does not transmit data in the second time period, the second MLD does not transmit data to the first MLD in the second time period.
If the first MLD is informed of the data transmission in the second time period, the second MLD receives the data from the first MLD in the second time period.
The related content for transmitting and receiving data based on the indication information of other content refers to the foregoing content, and will not be described in detail.
In summary, the method provided by the present application receives the transmission indication information from the first MLD, and performs data transceiving corresponding to the management operation of the first MLD on the established at least one link, so that the transmission efficiency, the transmission quality and the flexibility between the first MLD and the second MLD are improved, and the transmission performance of the wireless communication system is further improved. Moreover, since the first MLD not only considers the operation parameters of the at least one link, but also considers the operation parameters of at least two links to perform corresponding management operations, the management operations are more beneficial to the first MLD for saving the power consumption of the first MLD and avoiding inter-link interference.
