Background
802.11be systems, also known as extremely high throughput (EHT, extremely High Throughput) systems, enhance functionality through a range of system characteristics and mechanisms to achieve extremely high throughput. As the use of Wireless Local Area Networks (WLANs) continues to grow, it is increasingly important to provide wireless data services in many environments, such as homes, businesses, and hotspots. In particular, video traffic will continue to be the dominant traffic type in many WLAN deployments. The throughput requirements of these applications are evolving due to the advent of 4k and 8k video (20 Gbps uncompressed rate). New high throughput, low latency applications such as virtual or augmented reality, gaming, remote offices, and cloud computing will proliferate (e.g., latency for real-time gaming is less than 5 milliseconds).
In view of the high throughput and stringent real-time delay requirements of these applications, users desire to support their applications over a WLAN with higher throughput, higher reliability, less delay and jitter, and higher power efficiency. Users desire improved integration with Time Sensitive Networks (TSNs) to support applications on heterogeneous ethernet and wireless LANs. The 802.11be network aims to ensure the competitiveness of WLAN by further improving the overall throughput and reducing the delay while ensuring backward compatibility and coexistence with legacy technology standards. 802.11 compatible devices operating in the 2.4GHz,5GHz and 6GHz frequency bands.

While the present disclosure has been described in terms of an exemplary embodiment or embodiments, it should be understood that each aspect of the disclosure may be separately provided as a complete solution. The following embodiments and features of the embodiments may be combined with each other without conflict.
In embodiments of the present invention, "at least one" means one or more, and "a plurality" means two or more. In order to clearly describe the technical solution of the embodiment of the present invention, in the embodiment of the present invention, the words "first", "second", etc. are used to distinguish identical items or similar items having substantially the same function and effect, and those skilled in the art will understand that the words "first", "second", etc. do not limit the number and execution order, but only schematic and distinguish between the objects to be described, without separating the order, and without indicating that the number of devices in the embodiment of the present invention is particularly limited, and cannot constitute any limitation of the embodiment of the present invention. The term "comprising" is used to indicate the presence of the features stated hereafter, but does not exclude the addition of other features.
Firstly, the multilink technology according to the present invention will be briefly described, and in a multilink scenario, generally one physical device may include a plurality of logic devices, where the physical device may refer to devices such as a mobile phone, a television, and a projector, and the logic device may refer to a logic unit in the physical device, and belongs to a virtual function module. Each logical device can independently manage data transmission and reception, and each logical device independently operates on one link, and such a physical device is called a Multi-link device (MLD).
Fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system includes a multi-link access point AP MLD and a multi-link terminal STA MLD1, where the multi-link access point AP MLD includes three logical access points AP1, AP2 and AP3, where the three logical access points AP1, AP2 and AP3 operate on three different links respectively, and the embodiment of the present invention assumes that AP1 operates on a 2.4GHz link, sets a link identifier as link1, AP2 operates on a 5GHz link, sets a link identifier as link2, AP3 operates on a 6GHz link, and sets a link identifier as link3; the multi-link terminal STA MLD1 includes three logical terminals STA1, STA2 and STA3, which respectively establish a connection with AP1 on the link1, AP2 on the link2 and AP3 on the link 3. Meanwhile, each of the AP1, the AP2, and the AP3 is also connected with a plurality of terminals (not shown in the figure) supporting only a single link. After the connection is established, STA MLD1 and AP MLD use the default mode of traffic identification and link mapping, i.e. all traffic identifications are mapped onto each link.
It should be understood that fig. 1 is only a schematic diagram of an architecture of a communication system, and the number, types, etc. of devices in the communication system are not limited in the embodiments of the present invention, for example, a multi-link terminal and a multi-link access point may include only two logic devices or include more than four logic devices, and the number of logic devices in the multi-link terminal and the multi-link access point may be different. Furthermore, those skilled in the art will appreciate that the term "Access Point (AP)" in accordance with the principles and functions described herein may also be used to describe an access port or any other device capable of receiving and transmitting wireless signals within a network architecture, and thus, the use of an access point is merely exemplary.
In the communication system shown in fig. 1, when the AP MLD detects a delay-sensitive service, for example, online game, VR/AR service, the delay-sensitive service may be mapped to a specific link, so as to ensure the low delay requirement of the delay-sensitive service. The embodiment of the invention assumes that the AP2 and the AP3 are used for delay sensitive services, and the flow of a method for controlling data transmission is shown in figure 2, and comprises the following contents:
1001. the AP1, AP2 and AP3 of the AP MLD send broadcast messages (such as beacon messages or probe response messages), where the broadcast messages include mapping relations between service identifiers and links.
In some embodiments, the broadcast message may further include a mapping relationship mode, where the mapping relationship mode includes a mandatory execution mode and a non-mandatory execution mode, and indicates the multi-link terminal to determine whether to perform data transmission according to a mapping relationship between the service identifier and the link in the broadcast message according to the mapping relationship mode. Further, the broadcast message may also indicate the effective time of the mapping relationship between the service identifier and the link, such as indicating the start time and the end time of the mapping relationship, or indicating the start time and the duration of the mapping relationship, or indicating the waiting time and the duration of the mapping relationship between the service identifier and the link in the broadcast message. Illustratively, the broadcast message includes a service identifier and a Link mapping information element TID-to-Link mapping, where the information element includes the following parameters:
Mapping mode (optional): the mapping relation mode, if set to 1, represents forced execution, and set to 0 represents non-forced execution.
Switch count (optional): switching to the waiting time of the mapping relation indicated in the information element, for example, setting to be N: this mapping relationship will be used after N unit times are represented.
Duration (optional): and the effective time of the mapping relation indicated in the information element is set as M, and is effective in M unit time after the mapping relation is started.
Mapping info: the mapping relation between the service identifier and the link is set in the embodiment of the invention that all the services are mapped to link1, and the time delay sensitive service is also mapped to link2 and link3.
The Reason code (optional): the reason for setting such a mapping relation is, for example, that the current rate is low, or that the current link channel is heavily loaded, or the like.
It should be noted that, the AP MLD may send the mapping relationship between the service identifier and the link through a broadcast message, or may send the mapping relationship through other messages, for example, a service link mapping request message (for example, TID-to-Link mapping request message), which is not limited in the embodiment of the present invention.
1002. The STA MLD1 receives the broadcast message and performs data transmission according to information in the broadcast message.
Specifically, the STA MLD1 receives the broadcast message, if the broadcast message includes a service identifier and a link Mapping information element, a local service representation and link Mapping relation is set according to the Mapping relation indicated in the Mapping information element, when the STA MLD1 needs to send delay sensitive service data, the local service identifier and link Mapping relation is checked, and data transmission is performed according to the local service identifier and link Mapping relation, for example, if all services correspond to all links, one link is arbitrarily selected, or multiple links compete for sending opportunities to send the service data; if all traffic corresponds to part of the links, but the delay sensitive traffic data is also mapped to other links, then the competing transmission opportunities on one or more other links are preferentially selected to transmit the delay sensitive traffic data (e.g., transmitting data on link2 or link3, or transmitting data on both link2 and link 3); if the other links are busy, then transmission opportunities are contended for on the link to which all traffic corresponds to transmit delay sensitive traffic data (e.g., data on link 1). It should be appreciated that if all traffic corresponds to a portion of the links, but the delay sensitive traffic data is also mapped to other links, the transmission opportunity may be contended directly on one or more other links of all links to which the delay sensitive traffic corresponds to transmit the delay sensitive traffic data, which may also reduce the delay of the delay sensitive traffic.
In some embodiments, the TID-to-Link Mapping information element in the broadcast message further includes a Mapping mode parameter, and if the Mapping mode parameter indicates non-mandatory execution, the STA MLD1 may determine, according to its policy, whether to perform data transmission according to the Mapping relationship indicated by the Mapping info parameter, so that the content of the information element may be ignored, and the Mapping relationship indicated in the information element may also be executed; if the Mapping mode parameter indicates to force the implementation, the STA MLD1 needs to perform data transmission according to the Mapping relationship indicated by the Mapping info parameter. Further, the TID-to-Link Mapping information element may further include parameters Switch count and Duration, and if STA MLD1 sets a local Mapping relationship between a service identifier and a Link according to a Mapping relationship indicated in the Mapping info parameter, starts a new Mapping relationship after a time indicated by the Switch count parameter, sets a timer1, sets a timer value as a value of the Duration parameter, and sends service data according to the new Mapping relationship before the time of the timer 1; at the expiration of timer1, STA MLD1 modifies the local traffic identity and link mapping relationship to the default mode, i.e. all traffic maps to all links.
After step 1002, the AP MLD may further adjust the terminal service on each link, i.e. the AP MLD may send a message containing the mapping relationship between the service identifier and the link, to instruct the multi-link terminal to update the local mapping relationship between the service identifier and the link. If the message contains a mapping relation mode, the multi-link terminal can determine whether to update the local mapping relation between the service identifier and the link according to the mapping relation mode in the message, for example, if the mapping relation mode in the message indicates forced execution, the local mapping relation between the service identifier and the link is set as the mapping relation between the service identifier and the link in the message; if the Mapping mode in the message indicates non-forced execution, if the parameter Mapping mode in step 1001 indicates forced execution, the Mapping relationship between the service identifier in the message and the link is ignored, otherwise, if the parameter Mapping mode in step 1001 indicates non-forced execution, or a default configuration is currently being executed, the multi-link terminal can select whether to set the Mapping relationship between the local service identifier and the link as the Mapping relationship between the service identifier in the current message and the link according to its own policy. If the effective time of the mapping relationship is indicated in the message, the multi-link terminal needs to determine whether to update the local service identifier and the link mapping relationship according to the mapping relationship mode and the effective time of the mapping relationship, and then the load of the AP2 of the AP MLD is further increased, and the terminal that transmits the delay sensitive data on the link2 and the link3 needs to be split, but the setting characteristics of the link2 and the link3 for the delay sensitive service data transmission are not changed.
2001. The AP MLD sends a TID-to-Link mapping request message to the STA MLD1, which contains the following parameters:
mapping mode: the mapping relation mode, set to 1 in the embodiment of the present invention, represents forced execution.
Switch count: switching to the indicated mapping relation waiting time, for example, setting to be N: this mapping relationship will be used after N unit times are represented.
Duration: and the effective time of the indicated mapping relation is set as M, and is effective in M unit time after the mapping relation is started.
Mapping info: the mapping relation between the service identifier and the link is set in the embodiment of the invention that all the services are mapped to link1; the delay sensitive traffic is mapped to link3.
The Reason code: the reason for setting such a mapping relationship is, for example, that the current rate is low, or that the current link channel is heavily loaded, or the like.
2002. After receiving the TID-to-Link mapping request message, the STA MLD1 performs data transmission according to the information in the message, and specifically includes:
if the parameter Mapping mode value in the TID-to-Link Mapping request message is 0 and the timer1 is running, sending a service link Mapping response message (such as a TID-to-Link Mapping response message) to the AP MLD, wherein the message contains a status code for indicating rejection of the request, and in addition, the message can also contain a reflection code for indicating the forced Mapping relation;
If the parameter Mapping mode value in the TID-to-Link Mapping request message is 0 and the timer1 is up, determining whether to accept the Mapping relation of the request according to the self strategy, if yes, setting a status code to indicate to accept the request, if not, setting a status code to indicate to reject the request, and sending the status code to the AP MLD in the TID-to-Link Mapping response message;
if the parameter Mapping mode value in the TID-to-Link Mapping request message is 1, if the timer1 is running, the current Mapping relation is saved, namely Mapping1, and the Mapping relation in the request message is called Mapping2; starting a new mapping relation after the time indicated by the Switch count parameter in the request message, setting a timer2, setting the timer value as the value of the Duration parameter in the request message, and sending service data according to the new mapping relation mapping2 before the timer2 arrives; after the timer2 arrives, if the timer1 is still running, the service data is sent according to the stored mapping relation mapping1, and if the timer1 arrives, the service data is sent according to the default mapping relation.
After step 2002, when both timer1 and timer2 are running, STA MLD1 reads the broadcast message sent by AP MLD, if the broadcast message contains a service identifier and a link Mapping information element, and when the Mapping mode value in the information element is 1 and the Mapping relationship indicated by Mapping info is different from the Mapping relationship Mapping1 stored locally, deleting the Mapping information Mapping1 stored locally, and storing the Mapping relationship in Mapping info in the broadcast message at this time as Mapping relationship Mapping1, and in the running of timer2, still sending service data according to Mapping relationship Mapping 2.
The embodiment of the invention also provides a device for controlling data transmission, which comprises a service link mapping module, wherein the service link mapping module is used for executing the following steps:
receiving a first message sent by a first multi-link device, wherein the first message comprises a mapping relation between a first service identifier and a link, the mapping relation between the first service identifier and the link is set to be that all services are mapped to a first link, and a target service is also mapped to a second link, wherein the first link and the second link are different links;
and carrying out data transmission according to the mapping relation between the first service identifier and the link.
Optionally, the first message further includes a first mapping relationship mode, where the first mapping relationship mode includes a mandatory execution mode and a non-mandatory execution mode, and the performing data transmission according to the mapping relationship between the first service identifier and the link includes:
if the first mapping relation mode indicates forced execution, carrying out data transmission according to the mapping relation between the first service identifier and the link;
if the first mapping relation mode indicates non-forced execution, if the mapping relation mode corresponding to the mapping relation between the currently executed service identifier and the link indicates forced execution, neglecting the mapping relation between the first service identifier and the link, otherwise, deciding whether to perform data transmission according to the mapping relation between the first service identifier and the link according to a policy of the user.
