Embodiments of the present disclosure relate to a technical field of mobile communication. Specifically, the embodiments of the present disclosure relate to a communication link control method and apparatus, an electronic device, and a storage medium.
With the rapid development of mobile communication technologies, wireless fidelity (Wi-Fi) technologies have made huge advances in aspects, such as transmission rates and throughputs. At present, a research scope of Wi-Fi technologies is 320 MHz bandwidth transmission, aggregation and collaboration of multiple frequency bands, etc., and its main application scenarios include video transmission, augmented reality (AR), virtual reality (VR), etc.
Specifically, the aggregation and collaboration of multiple frequency bands refers to devices communicating with each other in 2.4 GHZ, 5.8 GHZ, 6 GHZ, and other frequency bands simultaneously. For a scenario in which devices communicate with each other in multiple frequency bands simultaneously, a new media access control (MAC) mechanism needs to be defined for management. In addition, the aggregation and collaboration of multiple frequency bands are expected to support low-latency transmission.
At present, technologies of the aggregation and collaboration of multiple frequency bands will support a maximum bandwidth of 320 MHz (160 MHz+160 MHz), and in addition, may also support 240 MHz (160 MHz+80 MHz) and other bandwidths supported by existing standards.
The currently studied Wi-Fi technologies support multi-link communication. For example, in a wireless local area network, a basic service set (BSS) may be composed of an AP and one or more stations (STAs) that communicate with the AP. The AP and the STAs may be multi-link devices (MLDs), respectively, and the MLDs support a function of enabling to simultaneously transmit and/or receive in multiple links (multi-link) at a same moment. Thus, there may be multiple links between an AP MLD and an STA MLD for communication.
Embodiments of the present disclosure provide a communication link control method and apparatus, an electronic device, and a storage medium.
In an aspect, an embodiment of the present disclosure provides a communication link control method, applied to a station device supporting multi-link Non-AP MLD. The method includes:

To improve spectrum utilization and adapt to a high-density communication environment, a non-simultaneous transmit and receive (NSTR) mechanism and a simultaneous transmit and receive (STR) mechanism are introduced. A random backoff mechanism is further introduced to implement the NSTR and the STR. Therefore, a manner of performing the random backoff in a multi-link scenario needs to be provided.
Embodiments of the present disclosure provide a communication link control method and apparatus, an electronic device, and a storage medium, to provide a manner of performing random backoff in a multi-link scenario.
The methods and the apparatuses are based on a same concept of the present disclosure. Because the methods and the apparatuses solve the problem in a similar principle, implementation of the apparatuses and the methods may refer to each other, and repetitive contents will not be repeated.
As shown in
At step 101, in a case where a random backoff operation is performed in a first communication link, operating mode information of a second communication link with respect to the first communication link is determined, where the second communication link is a communication link in an idle state.
In the embodiments of the present disclosure, the AP and the STA may be devices supporting multi-link, for example, the AP and the STA may be respectively represented as an AP MLD and a Non-AP MLD. For ease of description, an example in which one AP communicates with one STA in the multi-link is mainly described below, however, exemplary embodiments of the present disclosure are not limited thereto.
As a first example, referring to
In a wireless communication process, before the Non-AP MLD transmits data, the Non-AP MLD checks whether each of the communication links (hereinafter referred to as link) is in an idle state. If a link is in a busy state, the Non-AP MLD delays access and uses an exponential backoff algorithm to avoid occurrence of conflicts, and waits for the link to be idle again, thereby resulting in an access delay. This process is a random backoff process.
The operating mode information includes the STR or the NSTR, and there may be one or more second communication links in the idle state. The first communication link and the second communication link(s) may form an STR link pair, or may form an NSTR link pair. The device supporting the STR may simultaneously perform uplink communication and downlink communication in multiple communication links; however, the device supporting the NSTR, when performing the uplink communication in one link, cannot simultaneously perform the downlink communication in another link. The random backoff is independent in each communication link, and when the device senses that the channel is idle in the second communication link and senses that the channel is busy (that is, the channel is in an occupied state) in the first communication link, the corresponding random backoff is to be performed. Optionally, the first communication link and the second communication link are mutually an NSTR link pair.
It may be understood that when an operating mode of the second communication link with respect to the first communication link may form STR, the first communication link and the second communication link independently send data according to the operating mode for the STR.
At step 102, a target processing operation is performed on a contention window corresponding to the random backoff operation, and data is sent in the second communication link, where the operating mode information indicates that an operating mode of the second communication link with respect to the first communication link includes non-simultaneous transmit and receive (NSTR) communication links. Multiple link pairs formed by the first communication link and the second communication link may include the NSTR link pairs, or may include the NSTR link pairs and the STR link pairs.
In a process of performing the random backoff in a communication link, after previous frame data is transmitted completely, the Non-AP MLD attempts to transmit previously congested frame data after a time period of distributed inter-frame spacing (DIFS). A time period following the DIFS is a contention window (or a backoff window). The contention window may be further divided into slots, a number is randomly selected in a contention window to start counting-down, and then a channel is monitored once in each slot. When there is another device transmitting data, the current counting-down is frozen, and the counting-down continues when the channel is idle. Until the counting-down reaches 0, the node is allowed to perform data transmission. Through the backoff mechanism, some nodes with data to be transmitted may have their actual transmission times staggered on a timeline, to reduce a probability of the occurrence of the conflicts.
In the case where the random backoff is performed in the first communication link, and there is at least one second communication link that the at least one second communication link and the first communication link form an NSTR link pair, data is sent in the second communication link, and a target processing operation is performed on the contention window. The target processing operation includes, for example, releasing the contention window or maintaining the contention window.
Taking releasing the contention window as an example, in a case where a time length of a data packet sent in the second communication link is greater than or equal to a time length of the contention window, before completing data sending in the second communication link, the counting-down in the contention window has been completed, and it is no longer meaningful to maintain the contention window. Therefore, the contention window for performing the random backoff in the first communication link is released, to avoid electrical energy consumption caused by the Non-AP MLD due to performing the random backoff. Therefore, in embodiments of the present disclosure, in this scenario, the contention window generated for performing the random backoff in the first communication link is released, such that the random backoff is disabled, and electrical energy of the device is saved. Optionally, releasing the contention window includes, for example, configuring a value of the counting-down in the contention window as 0.
Then, taking maintaining the contention window as an example, in a case where the time length of the data packet sent in the second communication link is less than the time length of the contention window, before completing the data sending in the second communication link, the counting-down in the contention window has not been completed, and at this time, the device still needs to sense a channel state and wait for an opportunity to send the data in the first communication link. Therefore, the contention window is maintained at this time.
In the embodiments of the present disclosure, in the case where the random backoff operation is performed in the first communication link and there is the second communication link, in the idle state, supporting the NSTR, a target processing operation is performed on a contention window corresponding to the random backoff operation, and data continues to be sent in the second communication link. The embodiments of the present disclosure provide a manner of performing random backoff in a multi-link scenario.
In an optional embodiment, before determining the operating mode information of the second communication link with respect to the first communication link in the case where the random backoff operation is performed in the first communication link, the method includes:
Before the Non-AP MLD transmits data, the Non-AP MLD performs a channel clear assessment (CCA) operation for each of communication links, and determines whether each of the communication links is in an idle state according to a result of the channel clear assessment operation. When the first communication link is in the busy state and the second communication link is in the idle state, to avoid a contention conflict, the Non-AP MLD allows to continue to transmit data in the second communication link. The Non-AP MLD performs random backoff for the first communication link, generates the contention window, randomly selects a number in an contention window to start to perform counting-down, then monitors the link once in each slot, freezes the current counting-down when other device transmits data, and continues to perform the counting-down when the link is idle.
In the case where the random backoff is performed in the first communication link, operating modes of other second communication links are obtained, to determine a subsequent processing operation performed on the contention window.
In an optional embodiment, performing the target processing operation on the contention window corresponding to the random backoff operation includes:
In an optional embodiment, performing the target processing operation on the contention window corresponding to the random backoff operation includes:
As shown in
At step 301, in a case where a random backoff operation is performed in a first communication link, operating mode information of a second communication link with respect to the first communication link is determined according to a multi-link (ML) information element, where the second communication link is a communication link in an idle state.
In a process of performing the random backoff in a communication link, after previous frame data is transmitted completely, the Non-AP MLD attempts to transmit previously congested frame data after a time period of DIFS. A time period following the DIFS is a contention window (or a backoff window). The contention window may be further divided into slots, a number is randomly selected in a contention window to start counting-down, and then a channel is monitored once in each slot. When there is another device transmitting data, the current counting-down is frozen, and the counting-down continues when the channel is idle. Until the counting-down reaches 0, the node is allowed to perform data transmission. Through the backoff mechanism, some nodes with data to be transmitted may have their actual transmission times staggered on a timeline, to reduce a probability of the occurrence of the conflicts.
In the case where the random backoff is performed in the first communication link, operating mode information of the second communication link with respect to the first communication link is determined according to the multi-link (ML) information element. The multi-link (ML) information element includes multi-link control information, per-STA profile information, link information (link info), and common information (common info), etc.
The operating mode information includes the STR or the NSTR, that is, the first communication link and the second communication link form an STR link pair or an NSTR link pair. The device supporting the STR may simultaneously perform uplink communication and downlink communication in multiple communication links; however, the device supporting the NSTR, when performing the uplink communication in one link, cannot simultaneously perform the downlink communication in another link. The random backoff is independent in each communication link, and when the device senses that the channel is idle in the second communication link and senses that the channel is busy (that is, the channel is in an occupied state) in the first communication link, the corresponding random backoff is to be performed. Optionally, the first communication link and the second communication link are mutually an NSTR link pair.
It may be understood that when the operating mode information of the second communication link with respect to the first communication link is the STR, the first communication link and the second communication link respectively independently send data.
At step 302, a target processing operation is performed on a contention window corresponding to the random backoff operation, and data is sent in the second communication link, where the operating mode information indicates that an operating mode of the second communication link with respect to the first communication link includes non-simultaneous transmit and receive (NSTR) communication links.
The target processing operation includes, for example, releasing the contention window or maintaining the contention window.
In an optional embodiment, determining the operating mode information of the second communication link with respect to the first communication link according to the multi-link (ML) information element includes:
Optionally, the Non-AP MLD may carry information of frequency separations for STR between each of links in an initial association process (a multi-link establishment process), for example, a minimum unit of an separation is 20 MHz, and a maximum number of simultaneous links (the number of the separations) is 6; and when the Non-AP MLD determines, based on an operating frequency of each of the first communication link and the second communication link, that the information of the frequency separations for STR and the maximum number of simultaneous links cannot be met, the Non-AP MLD may determine that the operating modes of the first communication link and the second communication link are NSTR communication links, and the second communication link and the first communication link form an NSTR link pair.
In an optional embodiment, the information of the maximum number of simultaneous links and the information of the frequency separation for STR are carried in a common information (common Info) field of the ML information element.
As a second example, a format of the ML information element is shown in the following
In Table 1, the information of the maximum number of simultaneous links and the information of the frequency separation for STR are carried in the common Info field.
In an optional embodiment, the ML information element is carried in a target radio frame.
The target radio frame includes at least one of: a multi-link (ML) probe request frame, an association request frame, or a reassociation request frame. It can be understood that in addition to this, the target radio frame may also include other forms, which is not specifically limited here in embodiments of the present disclosure.
In the embodiments of the present disclosure, in the case where the random backoff operation is performed in the first communication link and there is the second communication link, in the idle state, supporting the NSTR, a target processing operation is performed on a contention window corresponding to the random backoff operation, and data continues to be sent in the second communication link. The embodiments of the present disclosure provide a manner of performing random backoff in a multi-link scenario.
Based on a principle same as the principle of the method provided in the embodiments of the present disclosure, an embodiment of the present disclosure further provides a station device. The station device may refer to a device providing voice and/or data connectivity to a user, a handheld device having a wireless link function, or another processing device connected to a wireless modem, etc.
As shown in
The determination module 401 is configured for, in a case where a random backoff operation is performed in a first communication link, determining operating mode information of a second communication link with respect to the first communication link, where the second communication link is a communication link in an idle state.
In the embodiments of the present disclosure, the AP and the STA may be devices supporting multi-link, for example, the AP and the STA may be respectively represented as an AP MLD and a Non-AP MLD. For ease of description, an example in which one AP communicates with one STA in the multi-link is mainly described below, however, exemplary embodiments of the present disclosure are not limited thereto.
As a first example, referring to
In a wireless communication process, before the Non-AP MLD transmits data, the Non-AP MLD checks whether each of the communication links (hereinafter referred to as link) is in an idle state. If a link is in a busy state, the Non-AP MLD delays access and uses an exponential backoff algorithm to avoid occurrence of conflicts, and waits for the link to be idle again, thereby resulting in an access delay. This process is a random backoff process.
The operating mode information includes the STR or the NSTR. The device supporting the STR may simultaneously perform the uplink communication and the downlink communication in multiple communication links; however, the device supporting the NSTR, when performing the uplink communication in one link, cannot simultaneously perform the downlink communication in another link. The random backoff is independent in each communication link, and when the device senses that the channel is idle in the second communication link and senses that the channel is busy (that is, the channel is in an occupied state) in the first communication link, the corresponding random backoff is to be performed. Optionally, the first communication link and the second communication link are mutually an NSTR link pair.
It may be understood that when the operating mode information of the second communication link with respect to the first communication link is the STR, the first communication link and the second communication link respectively independently send data.
The processing module 402 is configured for performing a target processing operation on a contention window corresponding to the random backoff operation, and sending data in the second communication link, where the operating mode information indicates that an operating mode of the second communication link with respect to the first communication link includes non-simultaneous transmit and receive (NSTR) communication links.

Therefore, the contention window is maintained at this time.
