Description

Technical Field

[0001] This disclosure relates to the field of communications, and more specifically, to communication methods and devices in wireless communications. Background Technology

[0002] Current Wi-Fi technology research focuses on 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, etc., with the aim of improving the speed and throughput by at least four times compared to existing standards. Its main application scenarios are video transmission, AR (Augmented Reality), VR (Virtual Reality), etc.

[0003] Multi-band aggregation and coordination refers to communication between devices simultaneously in frequency bands such as 2.4GHz, 5GHz, and 6GHz. Managing this simultaneous communication across multiple frequency bands requires defining a new MAC (Media Access Control) mechanism. Furthermore, it is expected that multi-band aggregation and coordination can support low-latency transmission.

[0004] The maximum bandwidth currently supported in multi-band aggregation and system technology is 320MHz (160MHz+160MHz), and it may also support 240MHz (160MHz+80MHz) and other bandwidths.

[0005] In current technology, stations (STAs) and access points (APs) can be multi-link devices (MLDs), meaning they support the ability to send and / or receive simultaneously under multiple connections. Therefore, in current technology, multiple connections can exist between STAs and APs, and research is underway on communication between these two types of devices under multiple connections.

[0006] Furthermore, current technologies employ a Block Ack (BA) mechanism to establish sessions for data transmission, and research has begun on acknowledgment mechanisms for multiple Traffic Identifiers (TIDs). However, existing technologies (e.g., existing standards) only have processing mechanisms for single TIDs; handling multiple TIDs according to a single TID mechanism would result in a waste of spectrum resources.

[0027] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0028] Figure 1 This is a diagram illustrating an example of the BA (Block Ack) mechanism according to an example embodiment.

[0029] Reference Figure 1 In phase (a), the initiator and receiver initiate a session through a handshake using ADDBA Request and ADDBA Response frames. Both ADDBA Request and ADDBA Response frames can be management frames and can exist as Action frames. Management frames (ADDBA Request and ADDBA Response frames) require acknowledgment (Ack). Figure 1 As shown, the process of establishing a session is as follows: the initiator sends an ADDBA request frame to the receiver; the receiver returns an acknowledgment frame (Ack) indicating that it has received the ADDBA request frame; then the receiver sends an ADDBA response frame to the ADDBA request frame; the initiator returns an acknowledgment frame (Ack) indicating that it has received the ADDBA response frame.

[0030] During the (a) setup phase, the format of the ADDBA request frame sent by the initiator to the receiver can be as shown in Table 1 below.

[0031] Table 1. ADDBA Request Frame Action Field Format

[0032] Order Information 1 Category 2 Block Ack Action 3 Dialog Token 4 Block Ack Parameter Set 5 Block Ack Timeout Value 6 Block Ack Starting Sequence Control 7 GCR Group Address element(optional) 8 Multi-band (optional) 9 TCLAS (optional) 10 ADDBA Extension (optional)

[0033] Referring to Table 1, an ADDBA request frame may include: a Category field, a Block Ack Action field, a Dialog Token field, a Block Ack Parameter Set field, a Block Ack Timeout Value field, and a Block Ack Starting Sequence Control field. Additionally, optionally, the ADDBA request frame may also include: a Groupcast with Retries (GCR) Group Address Element field, a Multi-band field, a TCLAS field, and an ADDBA Extension field.

[0034] The definition of the Block Ack Parameter Set field in Table 1 can be shown in Table 2 below.

[0035] Table 2. Block Ack Parameter Set fixed field

[0036]

[0037] In Table 2, MSDU can indicate a MAC Service Data Unit. The BA policy can be used to define whether the acknowledgment (Ack) is immediate or delayed. TID can indicate a communication identifier. Buffer Size can indicate the number of buffers available for a specific TID. For example, when the A-MSDU Supported field indicated by the Block Ack Parameter Set field sent by the station is equal to 0, the number of bytes that each buffer can hold is equal to the maximum value of the MSDU. When the A-MSDU Supported field is equal to 1 as indicated by the station, the number of bytes that each buffer can hold is equal to the maximum value of the A-MSDU supported by the station. It will be understood that although only one TID and its corresponding buffer size are shown in Table 2, this disclosure is not limited to this; multiple TIDs and buffer sizes corresponding to multiple ITDs can exist, and the number of bits for each TID and buffer size can also be changed.

[0038] Continue to refer to Figure 1 After the session connection is established, during the (b) data transmission & block acknowledgment phase, for example, during a transmission opportunity (TXOP), the initiator may continuously send multiple data frames, such as Quality of Service (QoS) data frames (i.e., Figure 1 The receiver sends a QoS Data frame and, after the data frame transmission ends, sends a Block Ack Req frame; the receiver then sends back Block Ack (BA) responses for multiple data frames.

[0039] In the (b) data transmission & block acknowledgment phase, for the Multi-TID Block AckReq (BAR), the Block Acknowledgment Request (BAR) information field can be defined as shown in Table 3 below.

[0040] Table 3. BAR Information Field (Multi-TID Block AckReq)

[0041]

[0042] In the (b) data transmission & block acknowledgment phase, for the BA (Multi-TID Block Ack), the block acknowledgment (BA) information field can be as shown in Table 4 below.

[0043] Table 4. BA Information Field (Multi-TID Block Ack)

[0044]

[0045] Each TID information (Per TID Info) subfield can be defined as shown in Table 5 below.

[0046] Table 5. Per TID Info subfield

[0047]

[0048] The definitions of the Block Ack Starting Sequence Control subfields in Tables 1, 3, and 4 are shown in Table 6 below.

[0049] Table 6. Block Ack Starting Sequence Control subfield

[0050]

[0051] Continue to refer to Figure 1 After the Block Ack confirmation is completed, the established session can be closed (deleted). Specifically, in the (c) deletion phase, the initiator can send a Delete BA Request frame, and the receiver will return an Ack confirmation frame. Further details will follow later. Figure 3 Table 7 details the DELBA request frame for multiple TIDs according to embodiments of this disclosure.

[0052] Figure 2 This is a diagram illustrating a multi-connection communication scenario according to an example embodiment.

[0053] In a wireless local area network (WLAN), a basic service set (BSS) can consist of an access point and one or more devices (non-AP STAs, which may be referred to as "sites" in this document) that communicate with the access point (AP). A basic service set can connect to a distribution system (DS) through its AP, and then connect to another basic service set to form an extended service set (ESS).

[0054] An Access Point (AP) is a wireless switch used in wireless networks and is the core of a wireless network. APs can be used as wireless base stations, primarily serving as bridges connecting wireless and wired networks. Using this type of access point (AP), wired and wireless networks can be integrated.

[0055] An access point (AP) may include software applications and / or circuitry to enable other types of nodes in a wireless network to communicate with the outside and inside of the wireless network via the AP. In some examples, for instance, the AP may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0056] As an example, non-AP STA can include, but is not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0057] In the exemplary embodiments of this disclosure, the AP and non-AP STA can be devices that support multi-connection communication, for example, they can be represented as AP MLD and non-AP STA MLD, respectively. For ease of description, the following mainly describes an example of an AP MLD communicating with a non-AP STA MLD under multi-connection conditions; however, the exemplary embodiments of this disclosure are not limited thereto.

[0058] exist Figure 2 In this text, by way of example only, AP MLD can represent an access point that supports multiple connection communication, and non-APSTA MLD can represent a site that supports multiple connection communication. (See also...) Figure 2 The AP MLD can operate in three connection modes, such as... Figure 2 As shown, AP1, AP2, and AP3, the non-AP STA MLD can also operate under all three connections, such as... Figure 2 STA1, STA2, and STA3 are shown. In... Figure 2In the example, it is assumed that AP1 communicates with STA1 through the corresponding first connection Link 1. Similarly, AP2 and AP3 communicate with STA2 and STA3 through the second connection Link 2 and the third connection Link 3, respectively. Furthermore, Link 1 to Link 3 can be multiple connections at different frequencies, such as connections at 2.4GHz, 5GHz, and 6GHz, or several connections with the same or different bandwidths at 2.4GHz, 5GHz, and 6GHz. Additionally, multiple channels can exist under each connection. However, it should be understood that... Figure 2 The communication scenarios shown are merely illustrative, and the inventive concept is not limited thereto. For example, the AP MLD can connect to multiple non-AP STA MLDs, or under each connection, the AP can communicate with multiple other sites.

[0059] In addition, although Figure 2 The diagram shows that the first connection Link 1 to the third connection Link 3 all belong to the same APMLD, but the embodiments of this disclosure are not limited to this. For example, the first connection Link 1 to the third connection Link 3 may be... Figure 2 The AP MLD shown is a connection shared with other AP MLDs. Furthermore, the first connection Link 1 to the third connection Link 3 can... Figure 2 The AP MLD shown is connected to Figure 2 In addition to the corresponding STA of the non-AP STA MLD shown, it can also be connected to the corresponding STA of other non-AP STA MLDs.

[0060] In addition, although Figure 2 The diagram shows that there are three connections between the AP MLD and the non-AP STA MLD, but the embodiments of this disclosure are not limited to this, and there may be more or fewer connections between them.

[0061] Combination Figure 1 A BA-based session connection can be established between two MLDs. The BA protocol between the two MLDs can be applied to all connections mapped to the TID corresponding to the BA protocol. According to an embodiment, for either the uplink (UL) or downlink (DL), all TIDs can be mapped to all established connections.

[0062] Combination Figure 1One of the AP MLD and the non-AP STA MLD can act as the initiator, and the other as the receiver. During (a) the establishment phase, the initiating multi-connection device can establish a BA with the receiving multi-connection device under any of the multiple connections. For example, to establish a BA between two multi-connection devices, a subsidiary device of the initiating multi-connection device can send an ADDBA request frame under any connection, indicating that a TID for establishing a BA is being sent. The corresponding subsidiary device of the receiving multi-connection device can respond using an ADDBA response frame. The corresponding subsidiary device of the receiving multi-connection device can accept or reject the ADDBA request. When accepted, a BA can be established between the two multi-connection devices. In one embodiment, at least one session communication between the initiating multi-connection device and the receiving multi-connection device can be established under any of the multiple connections. For example, a session communication under Link1 can be initiated using Link1, and furthermore, session communication under Link2 and / or Link3 can also be initiated using Link1. In the (b) data transmission & block acknowledgment phase, data transmission can occur under at least one connection, and data received under other connections (e.g., MPDU (MAC Protocol Data Unit)) can be acknowledged via BA frames under one connection. In the (c) deletion phase, at least one session communication can be deleted. As an example, all established session communication or BAs corresponding to multiple TIDs can be deleted under one connection. However, in the existing technology, a deletion mechanism for BAs with multiple TIDs is not defined. If the deletion of multiple TIDs is performed according to the single TID deletion mechanism in the existing standard process, many signaling processes will be required, thus wasting spectrum resources.

[0063] The following describes a method and apparatus for deleting multiple TIDs according to embodiments of the present disclosure.

[0064] Figure 3 This is a flowchart illustrating a communication method according to an example embodiment of the present disclosure.

[0065] Figure 3 The flowchart can be an operation performed by the initiator, which will be described below. Figure 3 This operation can be performed by the sender. For example, the sender can be one of the AP MLD and the non-AP STA MLD, and correspondingly, the receiver can be the other of the AP MLD and the non-AP STA MLD.

[0066] Reference Figure 3In step 310, a first message frame can be determined under any of the multiple connections. The first message frame may include first information indicating at least one Communication Identifier (TID). According to embodiments of this disclosure, the multiple connections can be multiple connections in different frequency bands supported by the initiating multi-connection device. According to embodiments of this disclosure, the first message frame can be used to terminate (delete) an established session connection corresponding to at least one TID; for example, the first message frame may be a DELBA request frame. Furthermore, at least one TID may correspond to different upper-layer services and QoS requirements. In embodiments of this disclosure, there can be many ways to determine the first message frame. For example, the initiator can generate the first message frame based on at least one of the following: network conditions, load conditions, hardware capabilities of the sending / receiving devices, service type, and relevant protocol specifications; this disclosure does not specifically limit this. In embodiments of this disclosure, the initiator can also obtain the first message frame from an external device; this disclosure does not specifically limit this.

[0067] The first information in the first message frame can be a multi-TID DELBA parameter set, the definition of which can be shown in Table 7 below.

[0068] Table 7. Definition of First Information

[0069]

[0070] Referring to Table 7, the first information may include at least one communication identifier, such as TID1, TID2, etc. shown in Table 7. According to embodiments of this disclosure, TIDs may correspond to different upper-layer services and QoS requirements.

[0071] In the case where Table 7 contains multiple TIDs (e.g., two or more TIDs), the first information of the first message frame can indicate, for example, to terminate (delete) the established session connections corresponding to multiple TIDs in one go.

[0072] Alternatively, the first information may also include a multi-connection device address, such as the MLD address shown in Table 7. The multi-connection device address can be used to identify connected devices in multi-connection communication. According to embodiments of this disclosure, the multi-connection device address corresponds to at least one communication identifier (TID). That is, the multiple TIDs to be deleted can be TIDs transmitted by the multi-connection devices indicated by the multi-connection device address.

[0073] According to embodiments of this disclosure, the multi-connection device address can identify the address of the initiating device that initiates the session, or the multi-connection device address can identify the address of the receiving device that responds to the session. For example, the multi-connection device address can be identified according to the Initiator subfield in Table 7. For example, the value of Initiator can be set to a first value (e.g., "1") to identify the initiator established by the BA mechanism. Figure 1 The Originator sends the first message frame (e.g., a DELBA request frame), and the MLD address is the initiator's MLD address; the Initiator value can be set to a second value (e.g., "0") to identify the responder established by the BA mechanism. Figure 1 The Recipient in the BA sends the first message frame (e.g., a DELBA request frame), and the Multiple Access Address (MLD address) is the MLD address of the responder. More generally, the MLD address is the MLD address of the initiator, that is, the MLD address of the initiator established by the BA (the one that initiates the connection). Figure 1 The Originator in the message can be the sender of the first message frame (e.g., a DELBA request frame).

[0074] According to embodiments of this disclosure, the first information may not include a Multiple Connection Address (MLD address). In this case, both parties can find the corresponding MLD address based on the MAC address and TID under each connection. According to embodiments, the two parties can exchange the MAC addresses under each connection through various message frames, for example, when establishing an association connection.

[0075] Furthermore, it is understood that each element shown in Tables 1 through 7 exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the tables must exist simultaneously as shown in the tables. The value of each element is independent of the values ​​of any other element in Tables 1 through 7. Therefore, those skilled in the art will understand that the value of each element in the tables of this disclosure is an independent embodiment.

[0076] In step 320, a first message frame may be sent. According to an embodiment, the first message frame may be sent under the connection where the first message frame is determined. According to another embodiment, a BA mechanism may be established under one of multiple connections. Based on the principle of BA mechanism establishment, the BA mechanism established under this connection can be applied under multiple connections. Therefore, the first message frame (DELBA request frame) may be sent under the BA mechanism establishment (i.e., the connection establishing the session) in multiple connections, or it may be sent under other connections in multiple connections (different from the connection establishing the BA mechanism (i.e., the connection establishing the session)).

[0077] According to embodiments of this disclosure, if the multi-connection device supports EMLSR (enhanced multi-link single-radio), the connection used to send the first message frame (DELBA request frame) may be different from the connection used to establish the BA mechanism (i.e., the connection used to establish a session).

[0078] Figure 4 This is a flowchart illustrating another communication method according to an example embodiment of the present disclosure. Figure 4 The flowchart can be the operation performed on the receiving end, that is, with Figure 3 The operation corresponding to the sender's operation is shown.

[0079] Reference Figure 4 In step 410, a first message frame is received under any of the multiple connections, wherein the first message frame may include first information indicating at least one communication identifier (TID). As described above with reference to Table 7, the first information may include at least one TID, and optionally, may also include a multiple connection device address corresponding to the at least one TID. According to an embodiment, the multiple connection device address may identify the address of the initiating device as the initiator of the session, or the multiple connection device address may identify the address of the receiving device as the responding device, which may be identified by the Initiator subfield in Table 7.

[0080] In step 420, the established session can be deleted based on the first message frame. For example, the BA corresponding to at least one TID of the corresponding multi-connection device can be deleted based on at least one TID and / or the multi-connection device address in the first message frame. In one embodiment, the establishment of the BA mechanism (such as...) Figure 1 The (a) setup phase shown can be single TID (i.e., BA is set up for one TID at a time), but the BA mechanism can delete multiple TIDs (i.e., BAs corresponding to multiple TIDs are deleted at once).

[0081] Figure 5This is a block diagram illustrating a communication device 500 according to an exemplary embodiment of the present disclosure. The communication device 500 may be a device supporting multiple connection communication and may include a processing module 510 and a transceiver module 420.

[0082] Figure 5 The communication device 500 shown can be applied to the sender. In this case, the processing module 510 can be used to determine a first message frame under any of the multiple connections, wherein the first message frame may include first information indicating at least one communication identifier (TID); the transceiver module 520 can be used to send the first message frame. As described above with reference to Table 7, the first information may include at least one TID, and optionally, may also include the address of the multiple connection device corresponding to the at least one TID. According to an embodiment, the multiple connection device address may identify the address of the initiating device as the initiator of the session, or the multiple connection device address may identify the address of the receiving device as the responding device, which can be identified by the Initiator subfield in Table 7. That is, in Figure 5 When the communication device 500 shown can be applied to the sender, the processing module 510 and the transceiver module 520 can perform the reference... Figure 3 For the sake of brevity, repeated descriptions of the operations described can be omitted here.

[0083] Figure 5 The communication device 500 shown can be applied to a receiver. In this case, the transceiver module 520 can be used to receive a first message frame, wherein the first message frame includes first information indicating at least one communication identifier (TID); the processing module 510 can be used to delete the established communication based on the first message frame. As described above with reference to Table 7, the first information may include at least one TID, and optionally, may also include a multi-connection device address corresponding to the at least one TID. According to an embodiment, the multi-connection device address may identify the address of the initiating device as the initiator of the session, or the multi-connection device address may identify the address of the receiving device as the responding device, which can be identified by the Initiator subfield in Table 7. That is, in Figure 5 When the communication device 500 shown can be applied to the receiver, the processing module 510 and the transceiver module 520 can perform the reference... Figure 4 For the sake of brevity, repeated descriptions of the operations described can be omitted here.
