Description

Technical Field

[0001] This disclosure relates to the field of mobile communication technology, and more specifically, to a method and related apparatus for processing a Network Allocation Vector (NAV) timer. Background Technology

[0002] With the rapid development of mobile communication technology, Wireless Fidelity (Wi-Fi) technology has made significant progress in terms of transmission rate and throughput. Currently, research on Wi-Fi technology focuses on areas such as 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, and its main applications include video transmission, Augmented Reality (AR), and Virtual Reality (VR).

[0003] Specifically, multi-band aggregation and coordination refers to devices communicating simultaneously in 2.4GHz, 5.8GHz, 6GHz, and other frequency bands. For scenarios where devices communicate simultaneously in multiple frequency bands, a new Media Access Control (MAC) mechanism needs to be defined for management. Furthermore, multi-band aggregation and coordination is expected to support low-latency transmission.

[0004] Currently, the maximum bandwidth supported by multi-band aggregation and coordination technology is 320MHz (160MHz+160MHz). In addition, it may also support 240MHz (160MHz+80MHz) and other bandwidths supported by existing standards.

[0005] In current Wi-Fi technologies, Non-Access Point Multi-Link Devices (Non-AP MLDs) supporting multiple connections in the enhanced Multi-Link Single Radio (eMLSR) mode can listen for frames across multiple active links. After completing frame exchange within one active link, they can switch back to listening mode across all active links. Specifically, a Non-AP MLD may receive frames under each active link. If it detects channel congestion, it will set its own Network Allocation Vector (NAV) timer to indicate channel busyness. However, how to set the NAV timer for other active links remains undetermined. Summary of the Invention

[0029] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0030] This disclosure provides a method and related apparatus for processing a Network Allocation Vector (NAV) timer in eMLSR mode.

[0031] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0032] like Figure 1 As shown in the illustration, this disclosure provides a method for processing a Network Allocation Vector (NAV) timer. Optionally, this method can be applied to a Non-Access Point (Non-AP) MLD that supports multiple connections. The method may include the following steps:

[0033] Step 101: In the enhanced multi-connection single-pass eMLSR mode, determine the connection type of the first communication connection of the Non-AP MLD.

[0034] In eMLSR mode, Non-AP MLD can listen to frames across multiple active communication links, and after completing frame interaction on one active communication link, it can switch back to listening mode on each active communication link.

[0035] In this context, the Non-AP MLD may receive radio frames under each active communication connection. If it detects that the channel is busy, it will set its own Network Allocation Vector (NAV) timer to indicate that the channel is busy. The NAV timer is used to implement virtual carrier sensing. When the NAV timer is not 0, it indicates that the channel is busy; when the NAV timer is 0, it indicates that the channel is idle.

[0036] In this embodiment of the disclosure, the Non-AP MLD can be a station (STA) device, and the aforementioned communication connection can be a communication connection between an access point device (AP MLD) supporting multiple connections and a Non-AP MLD. Each communication connection can be a connection at different frequencies, for example, connections at 2.4 GHz, 5 GHz, and 6 GHz, or several connections at 2.4 GHz with the same or different bandwidths. Furthermore, multiple channels can exist under each connection.

[0037] Optionally, the above connection types include simultaneous transmit and receive (STR) connections or non-simultaneous transmit and receive (NSTR) connections. That is, the active communication connections corresponding to the Non-AP MLD can all be STR connections or all be NSTR connections.

[0038] When all active communication connections corresponding to a Non-AP MLD are STR connections, the Non-AP MLD is in STR mode. This means the Non-AP MLD can receive radio frames from the AP MLD through one active STR connection and simultaneously send radio frames to the AP MLD through another active STR connection. When all active communication connections corresponding to a Non-AP MLD are NSTR connections, the Non-AP MLD is in NSTR mode. This means the Non-AP MLD can only receive radio frames from the AP MLD or send radio frames to the AP MLD through one active NSTR connection at any given time.

[0039] Optionally, the aforementioned Non-AP MLD includes a first communication connection and a second communication connection that are in an active state. The second communication connection includes an NSTR connection for receiving target radio frames or an STR connection for frame interaction.

[0040] When all active communication connections corresponding to the Non-AP MLD are of type NSTR, the second communication connection mentioned above is the NSTR connection that receives the target radio frame. The first communication connection mentioned above refers to any other active communication connection corresponding to the Non-AP MLD besides the second communication connection mentioned above.

[0041] The target radio frame mentioned above is either an initial control frame or a non-initial control frame (a radio frame other than the initial control frame) sent by the AP MLD. That is, the second communication connection mentioned above is an NSTR connection that receives the initial control frame sent by the AP MLD, or an NSTR connection that receives the non-initial control frame sent by the AP MLD.

[0042] Optionally, the aforementioned initial control frame may be a Multi-user Request to Send (MU-RTS) trigger frame or a Buffer Status Report Poll (BSRP) trigger frame.

[0043] When all active communication connections corresponding to a Non-AP MLD are of type STR connection, since a Non-AP MLD can simultaneously receive initial control frames from different AP MLDs across multiple communication connections, the aforementioned second communication is an STR connection that exchanges frames with the corresponding AP MLD after receiving the initial control frame. The aforementioned first communication connection refers to any other active communication connection corresponding to a Non-AP MLD besides the aforementioned second communication connection.

[0044] Step 102: Process the NAV timer of the first communication connection according to the connection type.

[0045] After determining the first and second communication connections that are active in the Non-AP MLD, and after determining the connection type of the first communication connection, the NAV timer of the first communication connection can be processed according to the connection type of the first communication connection.

[0046] In an optional embodiment, the connection type of the first communication connection is an STR connection; the NAV timer of the first communication connection is processed according to the connection type of the first communication connection, including:

[0047] In the case where the second communication connection is an STR connection for frame interaction, the NAV timer of the first communication connection is processed during the frame interaction process.

[0048] Each active communication connection in the Non-AP MLD corresponds to an independent NAV timer. During the operation of the Non-AP MLD, each NAV timer uses its remaining duration to indicate whether the channel is busy and the time the channel is occupied when it is busy.

[0049] When a Non-AP MLD receives an initial control frame from an AP MLD via a second communication connection and determines that it will engage in frame interaction with the AP MLD, it needs to process the NAV timer of the first communication connection during the frame interaction process. Furthermore, during the frame interaction process (i.e., while processing the NAV timer of the first communication connection), the NAV timer of the first communication connection is paused to allow for the completion of the NAV timer processing during this process.

[0050] That is, when a Non-AP MLD receives an initial control frame sent by an AP MLD through any active STR connection, and determines that it will perform frame interaction with the AP MLD through that STR connection, the NAV timer of other active STR connections will be processed during the frame interaction process.

[0051] In an optional embodiment, processing the NAV timer of the first communication connection during frame interaction includes:

[0052] Determine the remaining duration of the NAV timer for the first communication connection;

[0053] Determine the frame interaction duration;

[0054] The NAV timer of the first communication connection is processed during the frame interaction process based on the frame interaction duration and the remaining duration.

[0055] In other words, when processing the NAV timers of other active STR connections during frame interaction, the remaining duration of the NAV timer for any of the active STR connections can be determined. The remaining duration of the NAV timer for that STR connection indicates whether the channel corresponding to that STR connection is busy, and the time it occupies when busy. The frame interaction duration is further determined so that the NAV timer of that STR connection can be processed during frame interaction based on the frame interaction duration and the remaining duration.

[0056] In some optional embodiments, the NAV timer of the first communication connection is processed during the frame interaction process based on the frame interaction duration and the remaining duration, including:

[0057] If the remaining duration of the NAV timer of the first communication connection is greater than the frame interaction duration, the remaining duration of the NAV timer of the first communication connection is updated to the first duration during the frame interaction process; wherein, the first duration is the difference between the remaining duration of the NAV timer of the first communication connection and the duration of the frame interaction.

[0058] If the remaining duration of the NAV timer of the first communication connection is less than or equal to the frame interaction duration, the remaining duration of the NAV timer of the first communication connection is updated to 0 during the frame interaction process.

[0059] Furthermore, after completing frame interaction with the corresponding Non-APMLD through the second communication connection, the frame listening state can be switched under each active communication connection (first communication connection and second communication connection).

[0060] That is, when processing the NAV timers of other active STR connections during frame interaction, the remaining duration of the NAV timer of any of the other active STR connections can be determined first.

[0061] Furthermore, if the remaining duration of the NAV timer is greater than the frame interaction duration, the NAV timer is paused during the frame interaction process, and its remaining duration is updated to the product of the remaining duration of the NAV timer and the frame interaction duration (the first duration). After completing the frame interaction process, the connection under the STR corresponding to the NAV timer switches to the frame listening state. At this time, the NAV timer starts and represents the occupancy time of the corresponding channel under busy conditions based on the updated remaining duration.

[0062] If the remaining duration of the NAV timer is less than or equal to the frame interaction duration, the NAV timer is paused during the frame interaction process, and its remaining duration is updated to 0. After the frame interaction process is completed, the STR connection corresponding to the NAV timer switches to the frame listening state. Since the remaining duration of the NAV timer is 0, it indicates that the corresponding channel is idle.

[0063] In an optional embodiment, the connection type of the first communication connection is an NSTR connection; processing the NAV timer of the first communication connection according to the connection type of the first communication connection includes:

[0064] If the target wireless frame received through the second communication connection is an initial control frame, the NAV timer of the first communication connection shall not be updated.

[0065] If the target wireless frame received through the second communication connection is not an initial control frame, the processing duration corresponding to the non-initial control frame is determined, and the remaining duration of the NAV timer of the first communication connection is updated to the processing duration.

[0066] That is, if the Non-AP MLD receives the initial control frame sent by the AP MLD through any active NSTR connection, there is no need to process the NAV timers of other active NSTR connections.

[0067] If a Non-AP MLD receives a non-initial control frame (other frame) sent by an AP MLD through any active NSTR connection, the processing time corresponding to the non-initial control frame can be determined first.

[0068] Furthermore, for any NAV timer of any NSTR connection in other active NSTR connections, the remaining duration of the NAV timer can be directly updated to the processing duration corresponding to the non-initial control frame. In this case, the NAV timer represents the occupancy time of the corresponding channel under busy conditions based on the updated remaining duration.

[0069] In an alternative embodiment, the Non-AP MLD device needs to wait for the same amount of time as the processing time, and then switch to the listening state under each active communication connection (first communication connection and second communication connection).

[0070] In one optional embodiment, determining the processing duration of non-initial control frames includes at least one of the following:

[0071] The processing duration is determined based on the duration field in the Medium Access Control (MAC) frame header of the non-initial control frame.

[0072] The processing time is determined based on the time length corresponding to the length field in the physical layer PHY (Physical) frame header of the non-initial control frame.

[0073] As an example, when a Non-AP MLD receives a non-initial control frame sent by an AP MLD through any active NSTR connection, the time length corresponding to the duration field in the MAC frame header of the non-initial control frame can be determined as the processing time of the non-initial control frame.

[0074] As an example, when a Non-AP MLD receives a non-initial control frame sent by an AP MLD through any active NSTR connection, the time length corresponding to the length field in the physical layer PHY frame header of the non-initial control frame can be determined as the processing time of the non-initial control frame.

[0075] It is understandable that when the Non-AP MLD is in STR mode, after frame interaction is performed through any active STR connection and the NAV timers of other active STR connections are updated, the Non-AP MLD can listen for frames on each active STR connection. Upon receiving the initial control frame sent by the APMLD through any active STR connection and determining to engage in frame interaction, the NAV timers of other active STR connections are reprocessed during the frame interaction process based on the aforementioned implementation method.

[0076] When the Non-AP MLD is in NSTR mode, upon receiving a non-initial control frame through any active NSTR connection, it waits for the processing time of the non-initial control frame before resuming listening on each active NSTR connection. Upon receiving an initial control frame through any active NSTR connection, it does not update the NAV timers of other active NSTR connections. Upon receiving a non-initial control frame through any active NSTR connection, it updates the NAV timers of other active NSTR connections based on the processing time of the initial control frame and waits for the corresponding processing time.

[0077] In this embodiment of the disclosure, in eMLSR mode, when the Non-AP MLD receives a target radio frame through any active NSTR connection, it can update the NAV timer of other active NSTRs, or when performing frame interaction through any active STR connection, it can process the NAV timer of other active STR connections, thus having high applicability.

[0078] Based on the same principles as the methods provided in the embodiments of this disclosure, the embodiments of this disclosure also provide a Non-APMLD that supports multiple connections. The Non-APMLD may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem, etc.

[0087] Optionally, in this embodiment of the disclosure, the processing module 22 is used for:

[0088] If the remaining duration is greater than the frame interaction duration, the remaining duration of the NAV timer of the first communication connection is updated to the first duration during the frame interaction process; wherein the first duration is the difference between the remaining duration and the frame interaction duration.

[0089] If the remaining duration is less than or equal to the frame interaction duration, the remaining duration of the NAV timer of the first communication connection is updated to 0 during the frame interaction process.

[0090] Optionally, in this embodiment of the disclosure, the connection type of the first communication connection is an NSTR connection; the processing module 22 is used for:

[0091] If the target wireless frame is the initial control frame, the NAV timer of the first communication connection will not be updated.

[0092] If the target wireless frame is not the initial control frame, determine the processing duration corresponding to the non-initial control frame, and update the remaining duration of the NAV timer of the first communication connection to the processing duration.

[0093] Optionally, in this embodiment of the disclosure, the processing module 22 is used for:

[0094] The processing duration is determined based on the time length corresponding to the duration field in the Media Access Control (MAC) frame header of the aforementioned non-initial control frame.

[0095] The processing time is determined based on the time length corresponding to the length field in the physical layer PHY frame header of the aforementioned non-initial control frame.

[0096] Optionally, in this embodiment of the present disclosure, the processing module 22 is used to switch to a listening state under the first communication connection and the second communication connection after the frame interaction process is completed.

[0097] Optionally, in this embodiment of the present disclosure, the processing module 22 is used to switch to a listening state under the first communication connection and the second communication connection after waiting for the processing time.

[0098] In this embodiment of the disclosure, in eMLSR mode, the above-described device can update the NAV timers of other active NSTRs when the Non-AP MLD receives a target radio frame through any active NSTR connection, or process the NAV timers of other active STR connections when the Non-AP MLD performs frame interaction through any active STR connection, thus having high applicability.
