Description

Technical Field

[0001] This disclosure relates to the field of mobile communication technology, and more specifically, to a communication method and apparatus, an electronic device, and a storage medium. Background Technology

[0002] With the rapid development of mobile communication technology, Wireless Fidelity (Wi-Fi) technology has made significant progress in 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 the current Wi-Fi technologies under research, the existing Block Ack (BA) mechanism can return 1024 MAC Service Data Units (MSDUs) under a single connection; however, for low-latency services, the existing BA mechanism takes a long time and may not be able to meet the requirements of low-latency transmission.

[0044] 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.

[0045] This disclosure provides a communication method, apparatus, electronic device, and storage medium to address the problem that existing BA mechanisms are insufficient to meet low-latency transmission requirements.

[0046] 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.

[0047] like Figure 1 As shown in the illustration, this disclosure provides a communication method. Optionally, the method can be applied to an electronic device, which is an initiating end, such as an access point (AP) or a station (STA). The method may include the following steps:

[0048] Step 101: Send the first data frame under the first communication connection with the receiving end.

[0049] In multi-connection scenarios, in order to improve spectrum utilization and adapt to high-density communication environments, two communication modes are introduced: Non-Simultaneous Transmit And Receive (NSTR) and Simultaneous Transmit And Receive (STR). In the STR scenario, transmission and reception can be carried out simultaneously under different communication connections, and there is no interference between the transmissions of each communication connection. However, typically, if BA feedback is performed after 1024 consecutive MSDU transmissions are completed, and the data is not correctly received, the sending end needs to retransmit, resulting in a longer transmission time. Therefore, in this embodiment of the present disclosure, the sending end sends a first data frame under a first communication connection (i.e., Link) with the receiving end. The first data frame can be, for example, an aggregation of the MSDUs (A-MSDU) or an aggregation of PPDUs. The PPDU includes a physical layer header preamble (PLCP Headerpreamble), a MAC Protocol Data Unit (MPDU), and / or an aggregation of the MPDUs (A-MPDU).

[0050] Optionally, the first communication connection is a communication connection between the sending end and the receiving end to establish a BA mechanism (negotiation of the initial BA length).

[0051] Step 102: Send a first acknowledgment request (BA) frame corresponding to the first data frame through the second communication connection with the receiving end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving (STR) connections.

[0052] The first communication connection and the second communication connection are a pair of simultaneous sending and receiving STR connections. When the sending end sends the first data frame under the first communication connection, it simultaneously sends the first BA Request frame under the second communication connection. The first BA Request frame is used to request the receiving end to provide BA feedback for the received first data frame. In this way, the receiving end can provide BA feedback while the sending end is transmitting data frames, without waiting for 1024 MSDUs to be transmitted, thus shortening the transmission time.

[0053] In this embodiment, the transmitting end first sends a first data frame through a first communication connection with the receiving end, and then sends a first BA Request frame corresponding to the first data frame through a second communication connection with the receiving end. BA feedback is performed simultaneously with the transmission of the first data frame, shortening the transmission time, meeting the transmission requirements of low-latency services, improving spectrum utilization, and adapting to high-density communication environments. This embodiment solves the problem that existing BA mechanisms are insufficient to meet low-latency transmission requirements.

[0054] See Figure 2 This disclosure also provides a communication method, optionally applicable to an electronic device, which is an initiator, such as an AP or STA. The method may include the following steps:

[0055] Step 201: Send an Add BA request frame to the receiving end through the first communication connection. The Add BA request frame includes initial bitmap information and initial BA start sequence number; wherein the initial bitmap information indicates the size of the BA buffer.

[0056] When establishing the BA mechanism (negotiation of the initial BA length) with the receiving end, the initiating end first sends an add BA request frame to the receiving end through the first communication connection. The add BA request frame carries the initial bitmap information, which is the size of the BA buffer, i.e., the amount of data that the BA buffer can hold, such as 32 bytes, 64 bytes, or 128 bytes. In addition, the add BA request frame also includes the initial BA start sequence number, which is used to identify the starting position of the data frame sent by the sending end.

[0057] Step 202: Send the first data frame under the first communication connection with the receiving end.

[0058] The sending end sends a first data frame under a first communication connection with the receiving end. The first data frame may be, for example, an AMSDU or an APPDU.

[0059] Step 203: Send a first acknowledgment request (BA) frame corresponding to the first data frame through the second communication connection with the receiving end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving (STR) connections.

[0060] The first communication connection and the second communication connection are a pair of simultaneous sending and receiving STR connections. When the sending end sends the first data frame under the first communication connection, it simultaneously sends the first BA Request frame under the second communication connection. In this way, the receiving end can perform BA feedback while the sending end is transmitting data frames, without having to wait for 1024 MSDUs to be transmitted, thus shortening the transmission time.

[0061] In an optional embodiment, after sending an Add BA request frame to the receiving end via the first communication connection, the method includes:

[0062] Receive the Add BA response frame sent by the receiving end.

[0063] When the receiving end receives the add BA request frame, it will send an add BA response frame back to the sending end, indicating that it supports the add BA request frame.

[0064] In an optional embodiment, the first BA Request frame includes a first BA start sequence number, which is the same as the initial BA start sequence number; in the first transmission after the BA mechanism is established, the BA start sequence number in the BA Request frame is the same as the initial BA start sequence number;

[0065] and / or

[0066] The first BA Request frame includes first bitmap information. The bytes indicated by the first bitmap information are smaller than the bytes indicated by the initial bitmap information, that is, the length of the first bitmap information is smaller than the buffer size negotiated in the BA establishment mechanism. For example, if the length of the BA bitmap in the BA establishment mechanism is 128 bytes, and the length of the feedback required by the first bitmap information is 32 bytes, the receiving end can provide feedback on the reception status of the 32-byte A-MSDU that has been transmitted, without having to wait for the 128 bytes to be transmitted before providing BA feedback. In this way, the bytes indicated by the initial bitmap information are transmitted in multiple times, and BA feedback is provided for each transmitted data frame to shorten the overall transmission time.

[0067] See Figure 3 This disclosure also provides a communication method, optionally applicable to an electronic device, which is an initiator, such as an AP or STA. The method may include the following steps:

[0068] Step 301: Send an Add BA request frame to the receiving end through the first communication connection. The Add BA request frame includes initial bitmap information and initial BA start sequence number; wherein the initial bitmap information indicates the size of the BA buffer.

[0069] Step 302: Send the first data frame under the first communication connection with the receiving end.

[0070] Step 303: Send a first acknowledgment request (BA) frame corresponding to the first data frame through the second communication connection with the receiving end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving (STR) connections.

[0071] Step 304: Receive BA frames under the second communication connection.

[0072] The sending end receives the BA frame from the receiving end, determines whether the receiving end has successfully received all the contents of the first data frame based on the feedback of the BA frame, and retransmits the BA Request frame (i.e., the second BA Request frame) of the data frames that were not successfully received in the second communication connection, as shown in step 305. It can be understood that if the contents of the first data frame were all successfully received, there is no need to retransmit it.

[0073] Step 305: In response to the BA frame, send a second BA Request frame under the second communication connection.

[0074] In an optional embodiment, the second BA Request frame includes a second BA start sequence number, which is the sum of the initial BA start sequence number and the initial bitmap information; and / or, in the second BA Request frame, the value of the starting sequence number is the sum of the BA bitmap length in the first BA request frame and the value of the starting sequence number in the first BA request frame.

[0075] The second BA Request frame includes second bitmap information. The bytes indicated by the second bitmap information are smaller than the bytes indicated by the initial bitmap information. For example, in establishing the BA mechanism, the length of the BA bitmap is 128 bytes, while the second bitmap information indicates that the required feedback length can be 32 bytes or 64 bytes. On the other hand, if the first bitmap information indicates that the required feedback length is 32 bytes, then the starting sequence number in the second BA Request frame is the 33rd (32+1). In this way, the bytes indicated by the initial bitmap information are transmitted in multiple transmissions, and BA feedback is performed for each transmitted data frame to shorten the overall transmission time.

[0076] In this embodiment of the disclosure, the transmitting end first sends a first data frame under a first communication connection with the receiving end, and then sends a first BA Request frame corresponding to the first data frame under a second communication connection with the receiving end; BA feedback is performed while transmitting the first data frame, which shortens the transmission time, meets the transmission requirements of low-latency services, improves spectrum utilization, and adapts to high-density communication environments.

[0077] See Figure 4 This disclosure also provides a communication method, optionally applicable to an electronic device, which is a receiving end, such as an AP or STA. The method may include the following steps:

[0078] Step 401: Receive the first data frame under the first communication connection with the sending end.

[0079] In multi-connection scenarios, to improve spectrum utilization and adapt to high-density communication environments, NSTR and STR communication methods are introduced. In STR scenarios, transmission and reception can be performed simultaneously under different communication connections without interference between each connection. However, typically, if BA feedback is performed after 1024 consecutive MSDU transmissions are completed, and the data is not correctly received, the transmitter needs to retransmit, resulting in longer transmission time. Therefore, in this embodiment, the transmitter sends a first data frame under a first communication connection with the receiver, and the receiver receives the first data frame under a first communication connection with the transmitter. The first data frame can be, for example, AMSDU or APPDU.

[0080] Optionally, the first communication connection is a communication connection between the sending end and the receiving end to establish a BA mechanism (negotiation of the initial BA length).

[0081] Step 402: Receive a first acknowledgment request (BA Request) frame corresponding to the first data frame under the second communication connection with the sending end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving STR connections.

[0082] The first communication connection and the second communication connection are a pair of simultaneous sending and receiving STR connections. The receiving end receives the first data frame under the first communication connection with the sending end, and at the same time receives the first BARequest frame under the second communication connection. Subsequently, BA feedback is performed under the second communication connection. In this way, the receiving end can perform BA feedback while the sending end is transmitting data frames, without waiting for 1024 MSDUs to be transmitted, thus shortening the transmission time.

[0083] In this embodiment, the receiving end receives a first data frame under a first communication connection with the sending end; and under a second communication connection with the sending end, it receives a first acknowledgment request (BA) frame corresponding to the first data frame. BA feedback is performed simultaneously with the transmission of the first data frame, shortening transmission time, meeting the transmission requirements of low-latency services, improving spectrum utilization, and adapting to high-density communication environments. This embodiment solves the problem that existing BA mechanisms are insufficient to meet low-latency transmission requirements.

[0084] See Figure 5 This disclosure also provides a communication method, optionally applicable to an electronic device, which is a receiving end, such as an AP or STA. The method may include the following steps:

[0085] Step 501: Receive an Add BA request frame sent by the sending end through the first communication connection. The Add BA request frame includes initial bitmap information and initial BA start sequence number; wherein the initial bitmap information indicates the size of the BA buffer.

[0086] When establishing the BA mechanism (negotiation of the initial BA length) with the sender, the receiver first receives the add BA request frame sent by the sender through the first communication connection, and obtains the initial bitmap information carried in the add BA request frame. The initial bitmap information is the size of the BA buffer, that is, the amount of data that the BA buffer can hold, such as 32 bytes, 64 bytes, or 128 bytes. In addition, the add BA request frame also includes the initial BA start sequence number. The start sequence number identifies the starting position of the data frame sent by the sender.

[0087] Step 502: Receive the first data frame under the first communication connection with the sending end;

[0088] The receiving end receives a first data frame under a first communication connection with the sending end. The first data frame may be, for example, an AMSDU or an APPDU.

[0089] Step 503: Receive the first acknowledgment request (BA Request) frame corresponding to the first data frame under the second communication connection with the sending end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving (STR) connections.

[0090] The receiving end receives the first data frame under the first communication connection with the sending end, and simultaneously receives the first BA Request frame under the second communication connection. Subsequently, BA feedback is performed under the second communication connection. In this way, the receiving end can perform BA feedback while the sending end is transmitting data frames, without waiting for 1024 MSDUs to be transmitted, thus shortening the transmission time.

[0091] In an optional embodiment, after receiving the Add BA request frame sent by the sender via the first communication connection, the method includes:

[0092] Send an add BA response frame to the receiving end;

[0093] When the receiving end receives the add BA request frame, it will send an add BA response frame back to the sending end, indicating that it supports the add BA request frame.

[0094] In an optional embodiment, the first BA Request frame includes a first BA start sequence number, which is the same as the initial BA start sequence number; in the first transmission after the BA mechanism is established, the BA start sequence number in the BA Request frame is the same as the initial BA start sequence number;

[0095] and / or

[0096] The first BA Request frame includes first bitmap information. The bytes indicated by the first bitmap information are smaller than the bytes indicated by the initial bitmap information, that is, the length of the first bitmap information is smaller than the buffer size negotiated in the BA establishment mechanism. For example, if the length of the BA bitmap in the BA establishment mechanism is 128 bytes, and the length of the feedback required by the first bitmap information is 32 bytes, the receiving end can provide feedback on the reception status of the 32-byte A-MSDU that has been transmitted, without having to wait for the 128 bytes to be transmitted before providing BA feedback. In this way, the bytes indicated by the initial bitmap information are transmitted in multiple times, and BA feedback is provided for each transmitted data frame to shorten the overall transmission time.

[0097] See Figure 6 This disclosure also provides a communication method, optionally applicable to an electronic device, which is a receiving end, such as an AP or STA. The method may include the following steps:

[0098] Step 601: Receive an Add BA request frame sent by the sending end through the first communication connection. The Add BA request frame includes initial bitmap information and initial BA start sequence number; wherein the initial bitmap information indicates the size of the BA buffer.

[0099] Step 602: Receive the first data frame under the first communication connection with the sending end;

[0100] Step 603: Receive a first acknowledgment request (BA Request) frame corresponding to the first data frame under the second communication connection with the sending end; wherein the first communication connection and the second communication connection are a pair of simultaneous sending and receiving (STR) connections.

[0101] Step 604: Send a BA frame under the second communication connection.

[0102] The receiving end sends back a BA frame under the second communication connection, indicating to the sending end that the receiving end has successfully received the content of the first data frame. If not all the content of the first data frame has been received, the sending end will retransmit the BA Request frame for the unreceived data frame, i.e., the second BA Request frame. The receiving end will then receive the BA Request frame again, as shown in step 605. It is understood that if the content of the first data frame has been successfully received, there is no need to retransmit it.

[0103] Step 605: Receive the second BA Request frame under the second communication connection.

[0104] In an optional embodiment, the second BA Request frame includes a second BA start sequence number, which is the sum of the initial BA start sequence number and the initial bitmap information; and / or, in the second BA Request frame, the value of the starting sequence number is the sum of the BA bitmap length in the first BA request frame and the value of the starting sequence number in the first BA request frame.

[0105] The second BA Request frame includes second bitmap information, where the bytes indicated by the second bitmap information are smaller than those indicated by the initial bitmap information. For example, in establishing the BA mechanism, the length of the BA bitmap is 128 bytes, while the second bitmap information indicates that the required feedback length can be 32 bytes or 64 bytes. On the other hand, if the first bitmap information indicates that the required feedback length is 32 bytes, then the starting sequence number in the second BA Request frame is the 33rd (32+1). In this way, the bytes indicated by the initial bitmap information are transmitted in multiple transmissions, and BA feedback is performed for each transmitted data frame to shorten the overall transmission time.

[0106] In this embodiment, the receiving end receives a first data frame under a first communication connection with the sending end; and under a second communication connection with the sending end, it receives a first block acknowledgment (BA) request frame corresponding to the first data frame. BA feedback is performed simultaneously with the transmission of the first data frame, shortening transmission time, meeting the transmission requirements of low-latency services, improving spectrum utilization, and adapting to high-density communication environments.
