Description

[0001] Divisional application statement

[0002] This application is a divisional application of Chinese invention patent application No. 202180000242.9, filed on January 12, 2021, entitled "Block Confirmation Method and Apparatus, Storage Medium". Technical Field

[0003] This disclosure relates to the field of communications, and in particular to block confirmation methods and apparatus, and storage media. Background Technology

[0004] Currently, to improve feedback efficiency, block acknowledgment (BA) can be used to provide feedback on the reception status of two or more data frames. BA can be based on the multi-link device (MLD) level, where MLD refers to a physical device that can communicate under multiple connections. That is, data frames with the same task identifier (TID) can be transmitted under different connections, and BA feedback can be performed under one of those connections.

[0005] When performing BA feedback, the BA frame includes the SSN (Starting Sequence Number). However, the current SSN setting is for single connection only. That is, the setting of SSN and the SN (sequence number) of each data frame cannot be applied to MLD-level BA feedback. Summary of the Invention

[0056] In this embodiment of the disclosure, before determining the SN of each data frame to be transmitted corresponding to the same service identifier under each connection, at least two data sending ends may send a request frame to request the establishment of a BA mechanism.

[0077] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0078] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0079] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0080] The BA frame structure specified in the current standard refers to... Figure 1A As shown, it includes the Frame Control field, Duration field, RA (Receiver Address) field, TA (Transmitter Address) field, BAR Control field, BAR information field, and FCS (Frame Check Sequence) field.

[0081] The structure of the BAR information field in the BA frame is referenced. Figure 1B As shown, it includes the Per TID Info field and the Block ACK Starting Sequence Control field. The structure of the PerTID Info field is shown below. Figure 1CAs shown, it includes the Reseved field and the TID Value field. The structure of the Block ACK Starting Sequence Control field is as follows: Figure 1D As shown, it includes the Fragment Number field and the Starting Sequence Number field.

[0082] Additionally, when sending data frames corresponding to the same TID, the data sender will carry the SN in the data frame. The structure of the SN is as follows: Figure 1E As shown, it includes the Fragment Number field and the Sequence Number field.

[0083] However, the current SSN settings are for single connections only, meaning that the settings for SSN and SN for each data frame cannot be applied to MLD-level BA feedback.

[0084] To address the aforementioned issues, this disclosure provides a BA (Data Sending) solution. The following section will first introduce the solution from the data sending end perspective.

[0085] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment. The method can be used in a data sending end group, which includes two or more data sending ends, and includes the following steps:

[0086] In step 201, the sequence number SN of each data frame to be transmitted corresponding to the same service identifier under each of at least two connections is determined.

[0087] In this embodiment of the disclosure, at least two connections include connections established by at least two data transmitters with the same data receiver. Each data transmitter determines the SN of each data frame to be transmitted under its own connection corresponding to the same TID. The data frames to be transmitted include, but are not limited to, MSDUs (MAC Service Data Units) or A-MSDUs (Aggregation MSDUs) to be transmitted.

[0088] In step 202, the data frames to be transmitted under each connection, including the SN, are sent.

[0089] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.

[0090] In this embodiment of the disclosure, at least two data transmitters send data frames to be transmitted, including SNs, under each connection to a data receiver.

[0091] In one possible example, at least two data transmitters can simultaneously and continuously transmit the data to be transmitted under each connection, including the SN.

[0092] In another possible example, at least two data transmitters can continuously transmit data to be transmitted, including the SN, under different connections, either in a time-sharing or simultaneous manner.

[0093] In the embodiments of this disclosure, the number of data frames to be transmitted under each connection may be the same or different, and this disclosure does not limit this. For example, the number of data frames to be transmitted under connection 1 is 4, and the number of data frames to be transmitted under connection 2 is 4 or 5, etc.

[0094] In the above embodiments, at least two data transmitting ends can respectively determine the sequence number (SN) of each data frame to be transmitted under each connection corresponding to the same service identifier, thereby transmitting the data frame to be transmitted including the SN under each connection, so that the data receiving end can determine the target BA frame, realize BA feedback based on MLD level, and improve feedback efficiency.

[0095] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0096] In step 301, a request frame for requesting the establishment of the BA mechanism is sent.

[0097] In this embodiment of the disclosure, the request frame includes, but is not limited to, the ADDBA request frame.

[0098] In step 302, based on the buffer size in the request frame, the maximum value of the SN of all data frames to be transmitted in the at least two connections is determined.

[0099] The above embodiments can be executed independently or in conjunction with any other embodiments of this disclosure, and this disclosure does not limit the scope of the embodiments. In the embodiments of this disclosure, at least two data sending ends can negotiate the buffer size with the data receiving end when the BA mechanism is established through request frames. Furthermore, the maximum value of the SN of all data frames to be transmitted under at least two connections established between at least two data sending ends and the data receiving end cannot exceed the buffer size.

[0100] In the above embodiments, before determining the SN of each data frame to be transmitted corresponding to the same service identifier under each connection, at least two data sending ends may send a request frame to request the establishment of a BA mechanism. The maximum value of the SN of all data frames to be transmitted is determined based on the buffer size in the request frame. The data receiving end can determine the maximum value of the SN of the received target data frame based on the buffer size in the request frame, which is simple to implement and has high availability.

[0101] In some optional embodiments, in at least two connections established between at least two data transmitters and the same data receiver, the number of SSNs of all data to be transmitted is one, and the SSN can be a preset value, wherein the preset value can be any integer, including but not limited to 0, 1, -1, etc., and this disclosure does not limit it.

[0102] Reference Figure 4 As shown, Figure 4 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0103] In step 401, the sequence number (SN) of each data frame to be transmitted corresponding to the same service identifier under each of the at least two connections is determined; in response to the fact that the first connection among the at least two connections belongs to a designated connection, the SN of each data frame to be transmitted under the first connection is determined sequentially based on the preset value.

[0104] In this embodiment of the disclosure, a designated connection can be determined from at least two connections. The designated connection is a connection in which the minimum value of the SN of the data frame to be transmitted is the SSN. That is, the SNs of the data frames to be transmitted under the designated connection are arranged sequentially starting from the SSN.

[0105] For example, at least two connections include connection 1 and connection 2, with a default value of 0. The first connection is connection 1, which belongs to a specified connection. There are 5 data frames to be transmitted under connection 1, and the SNs of these 5 data frames to be transmitted are 0, 1, 2, 3, and 4, respectively, which are determined in sequence.

[0106] In step 402, in response to the fact that the second connection of the at least two connections does not belong to the designated connection, the minimum value of the SN of the data frame to be transmitted under the second connection is determined.

[0107] In this embodiment of the disclosure, if the second connection does not belong to the designated connection, the minimum value of the SN under the second connection can be determined based on the maximum value of the SN of other connections. In one example, the minimum value of the SN under the second connection can be obtained by adding one to the maximum value of the SN of other connections.

[0108] For example, at least two connections include Connection 1 and Connection 2, with a default value of 0. The first connection is Connection 1, which belongs to the designated connection. There are 5 data frames to be transmitted under Connection 1, and the serial numbers (SNs) of these 5 data frames are 0, 1, 2, 3, and 4, respectively, determined in order. The maximum value of the SN under Connection 1 is 4, so the minimum value of the SN under Connection 2 is 5, that is, the SSN under Connection 2 is 5.

[0109] If there is also a connection 3, and the maximum value of the SN already determined in connections 1 and 2 is 8, the minimum value of the SN for connection 3 is 9, and so on.

[0110] In step 403, based on the minimum value of the SN, the SN of each data frame to be transmitted under the second connection is determined sequentially.

[0111] For example, the second connection is connection 2. The minimum value of the SN under connection 2 is 5. There are 4 data frames to be transmitted under connection 2. Then the SNs of the 4 data frames to be transmitted under connection 2 are 5, 6, 7 and 8 respectively.

[0112] For example, the second connection is connection 3. The minimum value of the SN under connection 3 is 9. The SNs of the four data frames to be transmitted under connection 3 are 9, 10, 11 and 12 respectively.

[0113] Of course, in this embodiment of the disclosure, the maximum value of the SN of the data frame to be transmitted cannot exceed the buffer size of the request frame used to request the establishment of the BA mechanism. For example, if the buffer size is 15, the maximum value of the SN of all data frames to be transmitted needs to be less than or equal to 15.

[0114] In the above embodiments, the number of SSNs set by at least two data transmitters for all data frames to be transmitted can be one, and the SSN is a preset value. Accordingly, the at least two data transmitters can determine the SN of each data frame to be transmitted under each connection based on the SSN. The data receiver can perform BA feedback according to the BA frame structure in related technologies, which conforms to the development of communication standards and achieves the purpose of BA feedback based on MLD level.

[0115] In some optional embodiments, in at least two connections established between at least two data transmitters and the same data receiver, the starting sequence number (SSN) of the data frame to be transmitted under each connection is a preset value. The preset value can be any integer, including but not limited to 0, 1, -1, etc., and this disclosure does not limit it. That is, the number of SSNs is two or more, and the number of SSNs is the same as the number of connections in the at least two connections.

[0116] For example, at least two connections include connection 1, connection 2 and connection 3, the number of connections is 3, the number of SSNs is also 3, the SSN of the data frame to be transmitted under connection 1 is the preset value, and the SSN of the data frame to be transmitted under connection 2 and connection 3 is also the preset value.

[0117] Reference Figure 5 As shown, Figure 5 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0118] In step 501, based on the preset value, the SN of each data frame to be transmitted under each connection is determined sequentially.

[0119] For example, there are at least two connections, including connection 1, connection 2, and connection 3, and the number of SSNs is also 3, with a default value of 0. The number of data frames to be transmitted under connection 1 is 4, so the SSNs of the 4 data frames to be transmitted under connection 1 are 0, 1, 2, and 3 respectively. The number of data frames to be transmitted under connection 2 is 3, so the SSNs of the 3 data frames to be transmitted under connection 2 are 0, 1, and 2 respectively. The number of data frames to be transmitted under connection 2 is 5, so the SSNs of the 5 data frames to be transmitted under connection 3 are 0, 1, 2, 3, and 4 respectively.

[0120] Of course, the maximum value of the serial numbers (SNs) of all data frames to be transmitted cannot exceed the buffer size of the request frame used to request the establishment of the BA mechanism, and the total number of all data frames to be transmitted cannot exceed the buffer size of the request frame used to request the establishment of the BA mechanism. For example, if the buffer size is 15, the maximum value of the serial numbers (SNs) of all data frames to be transmitted in Connection 1, Connection 2, and Connection 3 cannot exceed 15, and the total number of all data frames to be transmitted in Connection 1, Connection 2, and Connection 3 cannot exceed 15.

[0121] In the above embodiments, the number of SSNs set by at least two data transmitters for all data frames to be transmitted can be multiple, and each SSN is a preset value. Accordingly, at least two data transmitters can determine the SN of each data frame to be transmitted under their own connection based on the SSN. When the data receiver performs BA feedback, the target BA frame needs to carry at least the connection identifier of each connection, thus achieving the purpose of BA feedback based on MLD level.

[0122] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.

[0123] The BA solution provided in this disclosure will now be introduced from the perspective of the data receiving end.

[0124] Reference Figure 6 As shown, Figure 6This is a flowchart illustrating a block confirmation (BA) method according to an embodiment. This method can be used at a data receiving end and includes the following steps:

[0125] In step 601, in response to receiving all target data frames corresponding to the same service identifier through at least two connections, a target BA frame for BA feedback of all target data frames is determined.

[0126] In this embodiment of the disclosure, after receiving all target data frames, the data receiver can receive a BA request frame through one of at least two connections. The BA request frame is used to request the data receiver to provide BA feedback.

[0127] In step 602, the target BA frame is fed back through one of the at least two connections.

[0128] In this embodiment of the disclosure, the terminal sends back the target BA frame through at least two connections that have received the BA request frame.

[0129] In the above embodiments, after receiving all target data frames corresponding to the same service identifier through at least two connections, the data receiving end can feed back the target BA frame through one of the connections, thereby achieving the purpose of BA feedback based on MLD level and improving feedback efficiency.

[0130] In some alternative embodiments, refer to Figure 7 As shown, Figure 7 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0131] In step 701, a request frame for requesting the establishment of the BA mechanism is received.

[0132] In embodiments of this disclosure, the data receiving end receives the request frame through at least two connections. In one example, the request frame includes, but is not limited to, an ADDBA request frame.

[0133] In step 702, based on the buffer size in the request frame, the maximum value of the sequence number SN of the target data frame for BA feedback is determined.

[0134] In this embodiment of the disclosure, the data receiver determines the maximum value of the SN of the target data frame for BA feedback based on the buffer size negotiated when the BA mechanism is established.

[0135] In the above embodiments, the data receiving end can determine the maximum value of the SN of the received target data frame based on the buffer size in the request frame, which is simple to implement and highly usable.

[0136] In some optional embodiments, the number of start sequence numbers (SSNs) of all target data frames received by the data receiver through at least two connections is one, and the SSN is a preset value, which can be any integer, such as 0, 1, etc. Then the data receiver can proceed according to... Figure 1A The structure shown determines the target BA frame.

[0137] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.

[0138] Reference Figure 8 As shown, Figure 8 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0139] In step 801, the SSN included in the target BA frame is determined to be the preset value.

[0140] In this embodiment of the disclosure, the data receiving end can set the SSN included in the target BA frame to the preset value. For example, if the preset value is 0, the SSN in the target BA is also set to 0.

[0141] In step 802, the first number of bits in the first bitmap for BA feedback included in the target BA frame is determined.

[0142] In this embodiment of the disclosure, the first number of bits can be the total number of target data frames received by the data receiver.

[0143] For example, if the data receiver receives 10 target data frames through at least two connections, then the number of the first bits of the first bitmap included in the target BA frame is 10.

[0144] In step 803, based on the first number of bits, each first bit value in the first bit diagram used to indicate the reception status of the target data frame is determined.

[0145] In this embodiment of the disclosure, the bit position of each first bit value corresponds one-to-one with the SN of each target data frame. For example, bit position 1 corresponds to a target data frame with SN 0, and the bit value at bit position 1 can indicate the reception status of the target data frame with SN 0. The bit value at bit position 2 can indicate the reception status of the target data frame with SN 1, and so on.

[0146] In one example, a bit value of 1 can be used to indicate that the target data frame was successfully received, and a bit value of 0 can be used to indicate that the target data frame was not received.

[0147] For example, if the first bit count is 6, and target data frames with SN numbers 0, 1, 2, and 5 are successfully received, while target data frames with SN numbers 3 and 4 fail to be received, then the first bit diagram includes 6 bit positions, and the first bit value of the 6 bit positions is in the order of 1, 1, 1, 0, 0, 1. It should be noted that target data frames 0, 1, 2, and 5 can be target data frames received through at least two different connections.

[0148] The above is merely an illustrative example. Other implementations that provide feedback on the reception status of all target data frames received through at least two connections in the BA frame should also fall within the scope of this disclosure.

[0149] In the above embodiments, the number of SSNs set by at least two data transmitters for all data frames to be transmitted can be one, and the SSN is a preset value. Accordingly, the at least two data transmitters can determine the SN of each data frame to be transmitted under each connection based on the SSN. The data receiver can perform BA feedback according to the BA frame structure in related technologies, which conforms to the development of communication standards and achieves the purpose of BA feedback based on MLD level.

[0150] In some optional embodiments, the data receiving end uses a preset value for the starting sequence number (SSN) of the target data frames under each of at least two connections; that is, the SSNs of the target data frames received under each connection are sequentially arranged starting from the preset value. In the embodiments of this disclosure, the determined target BA frame must include at least the connection identifier of each connection.

[0151] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.

[0152] Reference Figure 9 As shown, Figure 9 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0153] In step 901, it is determined that the target BA frame includes the connection identifier of each connection and a second bitmap that corresponds one-to-one with the connection identifier of each connection.

[0154] For example, at least two connections include connection 1 and connection 2, and the number of second bitmaps is also 2, with connection 1 corresponding to second bitmap 1 and connection 2 corresponding to second bitmap 2. Figure 2 .

[0155] In step 902, each second bit value in the second bitmap used to indicate the reception status of the target data frame under each connection is determined.

[0156] In this embodiment of the disclosure, the bit position of each second bit value corresponds one-to-one with the SN of each target data frame received under each connection.

[0157] For example, if the number of target data frames received under Connection 1 is 4, the second bit diagram 1 corresponding to Connection 1 includes 4 bit positions, which are used to indicate the reception status of the 4 target data frames under Connection 1.

[0158] In one example, a bit value of 1 can be used to indicate that the target data frame was successfully received, and a bit value of 0 can be used to indicate that the target data frame was not received.

[0159] For example, under connection 1, the target data frame with SN 0 or 1 is successfully received, while the target data frame with SN 2 or 3 fails to be received. The second bit diagram 1 corresponding to connection 1 includes 4 bit positions, and the second bit values ​​of the 4 bit positions are in the order of 1, 1, 0, 0.

[0160] In the above embodiments, the number of SSNs set by at least two data transmitters for the data frames to be transmitted can be multiple, and each SSN is a preset value. Accordingly, at least two data transmitters can determine the SN of each data frame to be transmitted under their own connection based on the SSN. When the data receiver performs BA feedback, the target BA frame needs to carry at least the connection identifier of each connection, thus achieving the purpose of BA feedback based on MLD level.

[0161] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.

[0162] In some alternative embodiments, refer to Figure 10 As shown, Figure 10 This is a flowchart illustrating a block confirmation (BA) method according to an embodiment, including the following steps:

[0163] In step 1001, a group of data transmitters consisting of at least two data transmitters determines the sequence number SN of each data frame to be transmitted under the same service identifier in at least two connections.

[0164] The at least two connections include connections established by the at least two data sending ends with the same data receiving end. Figure 10 This example uses only two data senders; however, in a more comprehensive application, more data senders may be included.

[0165] The number of starting sequence numbers (SSNs) for all data frames to be transmitted in the at least two connections is one, and the SSN is a preset value. If the first connection among the at least two connections belongs to a designated connection, the SN of each data frame to be transmitted under the first connection is determined sequentially based on the preset value. If the second connection among the at least two connections does not belong to the designated connection, the minimum value of the SN of the data frames to be transmitted under the second connection is determined. Further, based on the minimum value of the SN, the SN of each data frame to be transmitted under the second connection is determined sequentially.

[0166] In step 1002, at least two data transmitting ends transmit the data frames to be transmitted under each connection, including the SN.

[0167] In step 1003, in response to receiving all target data frames corresponding to the same service identifier through at least two connections, the data receiving end determines the target BA frame for BA feedback of all target data frames.

[0168] In this embodiment of the disclosure, the structure of the target BA frame is referenced. Figure 1A As shown. The SSN included in the target BA frame is the preset value. The target BA frame includes a first bitmap, where each first bit value of the first bitmap is used to indicate the reception status of the target data frame.

[0169] In step 1004, the target BA frame is fed back through one of the at least two connections.

[0170] In the above embodiments, the number of SSNs set by at least two data transmitters for all data frames to be transmitted can be one, and the SSN is a preset value. Accordingly, the at least two data transmitters can determine the SN of each data frame to be transmitted under each connection based on the SSN. The data receiver can perform BA feedback according to the BA frame structure in related technologies, which conforms to the development of communication standards and achieves the purpose of BA feedback based on MLD level.

[0171] Of course, the number of SSNs set by the at least two data transmitters for the data frames to be transmitted can be multiple, and each SSN is a preset value. Accordingly, the at least two data transmitters can determine the SN of each data frame to be transmitted under their own connection based on the SSN. When the data receiver performs BA feedback, the target BA frame needs to carry at least the connection identifier of each connection, which can also achieve the purpose of BA feedback based on MLD level.

[0172] The above embodiments can be executed independently or together with any other embodiments of this disclosure, and this disclosure does not limit the embodiments in this way.
