[0090] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0091] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present disclosure. The singular forms "a" and "the" used in the embodiments of the present 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" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0092] It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "when" as used herein may be interpreted as "when" or "in response to determining".

[0093] To better describe any embodiment of the present disclosure, an embodiment of the present disclosure takes an application scenario of wireless data transmission as an example for exemplary illustration.

[0094] Such as Figure 1As shown in the figure, an embodiment of the present disclosure provides an application scenario for wireless data transmission. In this application scenario, the wireless system includes an access point, Station 1, and Station 2. Among them, the access point is a device that supports simultaneous transmission and reception of multiple connections, Station 1 is a device that supports transmission or reception of multiple connections, and Station 2 is a device that supports single-connection transmission or reception. When Station 1 sends data to the access point on Connection A and receives the acknowledgment frame feedback from the access point at the same time, if Station 2 sends data to the access point on Connection B, since Station 1 is a device that does not support simultaneous transmission and reception, and Station 2 is a device that supports single-connection transmission or reception, Station 1 will cause communication interference to Station 2 (please refer to Figure 1 the time period indicated by C in

[0095] ), resulting in data transmission failure and wasting transmission resources. Figure 2 As shown in the figure, it is a method for indicating data transmission under multiple connections provided by an embodiment of the present disclosure. Please refer to Figure 2 . The method includes:

[0096] Step 21, receive a first data frame sent by a first station on a first connection.

[0097] Here, the multiple connections may refer to multiple bandwidths in a frequency band. Here, the frequency band may refer to 2.4 GHz, 5 GHz, or 6 - 7 GHz. The bandwidth may refer to the bandwidth of the spectrum operating in the frequency band. For example, 20 MHz, 40 MHz, etc. Here, one connection may correspond to one such bandwidth. In some embodiments, the multiple connections may be: connections of a basic service set (BSS) composed of the same channel bandwidth or different channel bandwidths in the same frequency band, or connections of a basic service set (BSS) composed of the same or different channel bandwidths on different frequency bands.

[0098] Here, the multiple connections can be understood as multiple channels for transmitting data. For example, each connection in the multiple connections corresponds to a channel for transmitting data. In a wireless communication system, there may be multiple connections between a station and an access point. For example, a first connection, a second connection, etc. For a station that only supports a single connection, it can only receive or send data on a single connection. For example, receive data on the first connection or send data on the first connection. For a station that supports multiple connections, it can send or receive data on multiple connections. For example, send data on both the first connection and the second connection at the same time; when sending data on the first connection, receive data on the second connection at the same time; receive data on both the first connection and the second connection at the same time. Here, the first station may be a station that supports simultaneous transmission and reception of multiple connections; the first station may also be a station that supports simultaneous transmission and reception of multiple connections.

[0099] Here, multiple sites may be included within the service area where the access point is located. Taking the smart meter wireless system as an example, the access point may be a base station, a routing device, etc. in the smart meter wireless system. The first site may be a smart meter in the smart meter wireless system. Here, the distance between the first site and the access point is within the coverage range of the access point to ensure that the first site can receive the message frame sent by the access point.

[0100] Step 22, generate an acknowledgment message frame of the first data frame containing time information according to the transmission status of the second data frame between the second site on the second connection; wherein, the time information is used to indicate: the time when the first site reconnects to the first connection after receiving the acknowledgment message frame; the second connection is different from the first connection.

[0101] In one embodiment, the second site may be a device that supports single - connection transmission or reception.

[0102] The first site and the second site can be regarded as any communication devices capable of accessing the access point, including but not limited to: mobile phones, smart home devices, and / or smart office devices.

[0103] In one embodiment, the time information may include the start time information, end time information, or waiting duration information for the first site to reconnect to the first connection again. For example, the time information may include that the start time for the first site to reconnect to the first connection is from 10:01:01 to 10:01:02, where "10:01:01" is the start time and "10:01:02" is the end time.

[0104] In one embodiment, the time information may be the waiting duration information for the first site to reconnect to the first connection after waiting for a set duration after receiving the acknowledgment message frame. For example, the time information is the waiting duration information that the first site waits for 2 ms to reconnect to the first connection after receiving the acknowledgment message frame.

[0105] In another embodiment, the time information may be the information about the time point when the first site reconnects to the first connection after receiving the acknowledgment message frame. For example, the time information is the information about the time point when the first site reconnects to the first connection at 10:00:10 after receiving the acknowledgment message frame. In the embodiments of the present application, since the first data frame is sent on the first connection, reconnecting to the first connection again means that after the first site sends the first data frame and receives the acknowledgment message frame, it reconnects to the first connection again. Here, after the first site reconnects to the first connection again, the first site can transmit data with the access point on the first connection.

[0106] Here, the transmission status may be that there is no data transmission between the second connection and the second site; it may also be that there is transmission of the second data frame between the second connection and the second site. When there is transmission of the second data frame between the second connection and the second site, it may be that the access point sends data to the second site, or it may be that the access point receives data sent by the second site.

[0107] Step 23, send the confirmation message frame on the first connection.

[0108] In one embodiment, the confirmation message frame may be a type of transmission control character sent by the access point to the first site, used to indicate that the received data has been acknowledged or the reception has failed. For example, if the confirmation message frame carries ACK, it means that the access point has successfully received the first message frame; if the confirmation message frame carries NACK, it means that the access point has failed to receive the first message frame.

[0109] In one embodiment, after the access point finishes receiving the first data frame sent by the first site each time; the access point will feedback to the first site a confirmation message frame indicating whether it has successfully received the first data frame.

[0110] In this embodiment, the confirmation message frame of the first data frame contains the time information. The first site can, according to the indication of the time information, access the first connection again after receiving the confirmation message frame. Since the time information is generated according to the transmission status of the second data frame between the second connection and the second site, it reflects the transmission status of the second data frame on the second connection. The first site accessing the first connection based on the time information can reduce the interference to the transmission of the second data frame between the second connection and the second site of the access point compared to randomly accessing the first connection.

[0111] As Figure 3 shown, it is a method for indicating data transmission under multiple connections provided by another embodiment of the present disclosure. Please refer to Figure 3 , in step 22, generating the confirmation message frame of the first data frame containing the time information according to the transmission status of the second data frame between the second connection and the second site includes:

[0112] Step 32, when there is no second data frame transmission between the second connection and the second site, generate the confirmation message frame whose time information indicates that the waiting duration for accessing the first connection again is zero.

[0113] Here, there is no second data frame transmission on the second connection with the second station, and the access of the first station to the first connection will not cause interference. Here, after receiving the acknowledgment message frame whose contained time information indicates that the waiting duration for the first station to access the first connection again is zero, the first station can immediately access the first connection, improving the data transmission efficiency under multi-connection. Here, when the waiting duration is zero, after receiving the acknowledgment message frame, the first station can be understood as accessing the first connection again and transmitting data with the access point on the first connection.

[0114] As Figure 4a shown, a method for indicating data transmission under multi-connection provided by another embodiment of the present disclosure is as follows. Please refer to Figure 4a , the method further includes:

[0115] Step 41, receiving the capability information of the first station and the capability information of the second station.

[0116] The capability information is information describing the communication capability of any station. For example, information describing whether a station supports multi-connection transceiver or only single-connection transceiver. Another example is that when supporting multi-connection transceiver, information on whether it only supports multi-connection transmission or multi-connection reception or supports both multi-connection transmission and reception.

[0117] Here, the capability information can be the capability information supporting both multi-connection transmission and reception, or the capability information supporting multi-connection transmission or reception, or the capability information supporting single-connection transmission or reception.

[0118] In one embodiment, the first station and the second station may send the capability information to the access point during the process of establishing a connection with the access point. For example, the first station and the second station may send the capability information to the access point during the process of entering the service range of the access point and establishing the first connection with the access point.

[0119] In one embodiment, the capability information of the first station and the capability information of the second station are carried in any one of the following message frames: probe request frame, association request frame, authentication request frame.

[0120] It should be noted that the access point may also send the capability information of the access point to the first station and / or the second station in a beacon frame, a probe request frame, or an association request frame.

[0121] In one embodiment, the capability information includes:

[0122] A first value indicating that the corresponding station supports multi-connection transmission and reception;

[0123] Or, a second value indicating that the corresponding station supports multi-connection transmission or multi-connection reception;

[0124] Or, a third value indicating that the corresponding station supports single-connection transmission or single-connection reception.

[0125] Please refer to Figure 4b , the capability information can be identified by the information field in the probe request frame, the association request frame, the authentication request frame, etc. The information field may include an information element bit field (Element ID), a length bit field (Length), and an information bit field (Information). Among them, the information bit field may occupy one byte. The information element bit field can be used to identify the station identity information. For example, the information element is located and contains 3 bit positions. When it is identified as "001", it identifies the first station; when it is represented as "010", it identifies the second station. The information bit field can be used to identify the capability information of the station. Here, the station includes the first station and the second station.

[0126] In one embodiment, the information bit field uses 2 bit positions to identify the capability information of the station. For example, when the value of the 2 bit positions is "00", it indicates that the station only supports single-connection transmission or single-connection reception; when the value of the 2 bit positions is "01", it indicates that the station supports multi-connection transmission or multi-connection reception; when the value of the 2 bit positions is "10", it indicates that the station supports multi-connection transmission and reception. It should be noted that according to the number of station capability information included in the station device, the number of bit positions of the bit field for identifying the capability information of the station can be adjusted. For example, when the number of station capability information included in the station device exceeds 4 types, 3 bit positions are required for identification.

[0127] Step 42, when there is a second data frame transmission with the second station on the second connection, determine the time information according to the capability information of the first station and the capability information of the second station.

[0128] In one embodiment, the time information includes: the waiting duration information for the first station to access the first connection after receiving the confirmation message frame. Here, the waiting duration information can be information including a time period. For example, the duration information is information including a time period of 2 ms. Then the first station waits for 2 ms after receiving the confirmation message frame and can access the first connection.

[0129] As shown in Figure 5 , a method for indicating data transmission under multi-connection provided by another embodiment of the present disclosure. Please refer to Figure 5 . In step 42, determining the time information according to the capability information of the first station and the capability information of the second station includes:

[0130] Step 52, when the first station supports multi-connection sending and receiving, and the second station supports multi-connection sending or multi-connection receiving, the waiting duration information is the frame length information for transmitting data with the second station on the second connection; or, when the first station supports multi-connection sending and receiving, and the second station supports single-connection sending or single-connection receiving, the waiting duration information is the frame length information for transmitting data with the second station on the second connection.

[0131] Here, when the first station supports multi-connection sending and receiving and the second station supports multi-connection sending or multi-connection receiving, or, when the first station supports multi-connection sending and receiving, and the second station supports single-connection sending or single-connection receiving, the access of the first station to the first connection will interfere with the data transmission between the access point and the second station on the second connection. Setting the waiting duration information as the frame length information for transmitting data with the second station on the second connection enables the first station to avoid the time period when the access point transmits data with the second station on the second connection and then access the first connection, reducing the interference with the data transmission between the access point and the second station on the second connection.

[0132] As shown in Figure 6 , a method for indicating data transmission under multi-connection provided by another embodiment of the present disclosure. Please refer to Figure 6 . In step 42, determining the time information according to the capability information of the first station and the capability information of the second station includes:

[0133] Step 61, when the first station supports multi-connection sending and receiving and the second station supports multi-connection sending and receiving, the waiting duration information is zero.

[0134] Here, since the first station supports multi-connection sending and receiving and the second station supports multi-connection sending and receiving, the transmission of the first data frame by the first station on the first connection will not interfere with the transmission of the data frame by the second station on the second connection, and the first station can access the first connection directly without waiting.

[0135] In one embodiment, the transmission of the second data frame between the second connection and the second station includes:

[0136] Receive the second data frame sent by the second station on the second connection;

[0137] Or, send the second data frame to the second station on the second connection.

[0138] In one embodiment, the basic service set identifier (BSSID, Basic Service Set Identifier) carried in the first data frame and the second data frame is the same or the basic service set coloring value BSS color is the same.

[0139] Here, when the basic service set identifiers BSSIDs are the same, the first station sending the first data frame and the second station sending the second data frame belong to the same network.

[0140] In one embodiment, the basic service set coloring values (BSS color, Basic Service Set color) carried in the first data frame and the second data frame are the same. Here, the basic service set coloring value is an identifier of an intra-physical layer protocol data unit (intra-PPDU) within the basic service set. The basic service set coloring value is used to identify that the physical layer protocol data unit belongs to the same basic service set BSS.

[0141] As Figure 7 shown, it is a method for indicating data transmission under multiple connections provided by another embodiment of the present disclosure. Applied to the first station, please refer to Figure 7 and the method includes:

[0142] Step 71, send a first data frame on a first connection.

[0143] Here, the multi-connection may refer to multiple bandwidths under a certain frequency band. Here, the frequency band may refer to 2.4 GHz, 5 GHz, or 6 - 7 GHz. The bandwidth may refer to the spectral bandwidth operating under these frequency bands. For example, 20 MHz, 40 MHz, etc. Here, one connection may correspond to one such bandwidth. In some embodiments, the multi-connection may be: a connection of a basic service set (BSS) composed of the same channel bandwidth or different channel bandwidths in the same frequency band, or a connection of a basic service set (BSS) composed of the same or different channel bandwidths on different frequency bands. Here, the multi-connection can be understood as multiple channels for transmitting data. For example, each connection in the multi-connection corresponds to a channel for transmitting data. In a wireless communication system, there may be multiple connections between a station and an access point. For example, a first connection, a second connection, etc. For a station that only supports single-connection, it can only receive or send data on a single connection. For example, receive data on the first connection or send data on the first connection. For a station that supports multi-connection, it can send or receive data on multiple connections. For example, send data simultaneously on the first connection and the second connection; when sending data on the first connection, receive data on the second connection simultaneously; receive data simultaneously on the first connection and the second connection. Here, the first station may be a station that supports multi-connection sending and receiving; the first station may also be a station that supports multi-connection sending and receiving.

[0144] Here, the service area where the access point is located may include multiple stations. Taking the smart meter wireless system as an example, the access point may be a base station, a routing device, etc. in the smart meter wireless system. The first station may be a smart meter, etc. in the smart meter wireless system. Here, the distance between the first station and the access point is within the coverage range of the access point to ensure that the first station can receive the message frame sent by the access point.

[0145] In one embodiment, the first station may be considered as any communication device that can access the access point, including but not limited to: mobile phones, smart home devices, and / or smart office devices.

[0146] Step 72, receive an acknowledgement message frame of the first data frame on the first connection; wherein, the acknowledgement message frame contains time information, and the time information is used to indicate: the time when the first station accesses the first connection after receiving the acknowledgement message frame.

[0147] In one embodiment, the time information may include the start time information, end time information, or waiting duration information for the first station to re-connect to the first connection. For example, the time information may include that the start time for the first station to re-connect to the first connection is from 10:01:01 to 10:01:02, where "10:01:01" is the start time and "10:01:02" is the end time.

[0148] In one embodiment, the time information may be the waiting duration information for the first station to connect to the first connection after waiting for a set duration after receiving the acknowledgment message frame. For example, the time information is the waiting duration information that the first station waits for 2 ms to connect to the first connection after receiving the acknowledgment message frame.

[0149] In another embodiment, the time information may be the information about the time point when the first station connects to the first connection after receiving the acknowledgment message frame. For example, the time information is the information about the time point when the first station connects to the first connection at 10:00:10 after receiving the acknowledgment message frame.

[0150] In one embodiment, the acknowledgment message frame may be a type of transmission control character sent by the access point to the first station, used to indicate that the received data has been acknowledged or the reception has failed. For example, if the acknowledgment message frame carries ACK, it means that the access point has successfully received the first message frame; if the acknowledgment message frame carries NACK, it means that the access point has failed to receive the first message frame.

[0151] In one embodiment, after the access point finishes receiving the first data frame sent by the first station each time; the access point will feedback an acknowledgment message frame to the first station indicating whether it has successfully received the first data frame.

[0152] Step 73, connect to the first connection according to the time information.

[0153] In one embodiment, when the time for connecting to the first connection indicated by the time information is 0, the first station directly connects to the first connection without waiting after receiving the acknowledgment message frame. When the time for connecting to the first connection indicated by the time information is 2 ms, the first station waits for 2 ms and then directly connects to the first connection after receiving the acknowledgment message frame. When the time for connecting to the first connection indicated by the time information is "10:00:01", the first station connects to the first connection at 10:00:01.

[0154] In an embodiment of the present application, since the first data frame is sent on the first connection, re-accessing the first connection means that after the first station sends the first data frame and receives the acknowledgment message frame, it re-accesses the first connection. Here, after the first station re-accesses the first connection, the first station can transmit data with the access point on the first connection.

[0155] As Figure 8 shown, a method for indicating data transmission under multiple connections provided by another embodiment of the present disclosure is provided. Please refer to Figure 8 , the method further includes:

[0156] Step 81, sending the capability information of the first station to the access point; wherein, the capability information of the first station is used to determine the time information.

[0157] Here, the capability information may be the capability information supporting simultaneous transmission and reception of multiple connections, or the capability information supporting transmission or reception of multiple connections, or the capability information supporting transmission or reception of a single connection.

[0158] In one embodiment, the first station may send the capability information to the access point during the process of establishing a connection with the access point. For example, the first station may send the capability information to the access point during the process of first establishing a connection with the access point when entering the service range of the access point.

[0159] The capability information is: information describing the communication capability of any station. For example, information describing whether a station supports multi-connection transceiver or only supports single-connection transceiver. Also, for example, when supporting multi-connection transceiver, whether it only supports multi-connection transmission or multi-connection reception or supports both multi-connection transmission and reception.

[0160] In one embodiment, the sending the capability information of the first station to the access point includes:

[0161] Sending the capability information of the first station through a probe request frame, an association request frame, or an authentication request frame.

[0162] In one embodiment, the sending the capability information of the first station to the access point includes:

[0163] When the first station supports multi-connection transmission and reception, sending the capability information with a first value to the access point;

[0164] Or, when the first station supports multi-connection transmission or multi-connection reception, sending the capability information with a second value to the access point;

[0165] Alternatively, when the first station supports single - connection transmission or single - connection reception, send the capability information with a third value to the access point.

[0166] Please refer to again Figure 4b Figure 4b , the capability information can be identified by the information fields in the probe request frame, the association request frame, the authentication request frame, etc. The information field can include an information element bit field (Element ID), a length bit field (Length), and an information bit field (Information). Among them, the information bit field can occupy one byte. The information element bit field can be used to identify the station identity information. For example, the information element is located in a 3 - bit field. When it is identified as "001", it identifies the first station; when it is represented as "010", it identifies the second station. The information bit field can be used to identify the capability information of the station. Here, the station includes the first station.

[0167] In one embodiment, the information bit field uses 2 bits to identify the capability information of the station. For example, when the value of the 2 - bit field is "00", it indicates that the station only supports single - connection transmission or single - connection reception; when the value of the 2 - bit field is "01", it indicates that the station supports multi - connection transmission or multi - connection reception; when the value of the 2 - bit field is "10", it indicates that the station supports multi - connection transmission and reception. It should be noted that according to the number of types of station capability information included in the station device, the number of bits for identifying the capability information of the station can be adjusted. For example, when the number of types of station capability information included in the station device exceeds 4 types, 3 bits are required for identification.
