[0091] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0092] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include 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 associated listed items.

[0093] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type 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 word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0094] The execution entities involved in the embodiments of the present disclosure include but are not limited to: wireless communication networks, especially Wi-Fi networks such as those under the IEEE802.11a / b / g / n / ac standards, and network devices under the IEEE802.11be standard in next-generation Wi-Fi networks, where the network devices include but are not limited to: wireless access point (AP) devices such as Wi-Fi routers, wireless stations (STA), user terminals, user nodes, mobile terminals or tablet computers, etc.

[0095] One application scenario of the disclosed embodiment is that when data frames are transmitted, a traffic identifier (TID) is assigned to the data frames to ensure the quality of service (QoS) of the data frame transmission. When the TID is set to 0-7, it indicates that the data frame is based on the enhanced distributed channel access (EDCA) access strategy. The larger the number, the better the QoS protection required.

[0096] In the vision proposed by IEEE802.11be, the Add Traffic Stream (ADDTS) request and ADDTS response mechanism are introduced into the existing standard. The ADDTS request and ADDTS response mechanism is used by both parties of the data frame to negotiate the transmission parameters for different TID data frames. The format of the variable action field of the ADDTS request frame is as follows: Figure 1 As shown, the ADDTS response frame variable action field format is as follows Figure 2shown.

[0097] The IEEE802.11be standard supports multi-transmission connection communications and puts forward high reliability and low latency requirements for data frames. The existing DECA mechanism cannot meet the requirements of multi-connection transmission and high reliability and low latency data frames.

[0098] like Figure 3 As shown, this exemplary embodiment provides an information transmission method, which can be applied to a data frame transmitting end of wireless communication, including:

[0099] Step 301: In a first transmission connection among multiple transmission connections, an ADDTS request frame is sent, wherein the ADDTS request frame at least includes a service identifier TID with a value greater than 7.

[0100] Here, the data frame transmitter may be an access point (AP) or a station (STA) in a Wi-Fi communication system, and the data frame receiver may be an AP or a STA in the Wi-Fi communication system.

[0101] The data frame sender and the data frame receiver can establish one or more transmission connections in multiple frequency bands. The data frame sender can send data frames through a single transmission connection or send different data frames through multiple transmission connections.

[0102] Before sending a data frame, the data frame transmitter can send an ADDTS request frame to the data frame receiver, providing the receiver with transmission parameters for data frames with different TIDs, ensuring that the data frame transmission meets QoS requirements. Transmission parameters may include data rate, Media Access Control Service Data Unit (MSDU) bit count, etc. The data frame receiver can determine the final transmission parameters based on the transmission connection load and return the recommended transmission parameters to the data frame transmitter via an ADDTS response frame.

[0103] In related art, in order to ensure QoS of data frame transmission, different TIDs are assigned to data frames according to the QoS requirements of different services, and the range of TIDs is 0 to 7. Different TIDs represent different QoS requirements.

[0104] The IEEE 802.11be standard proposes the requirement for highly reliable and low-latency data frames. This requirement places higher reliability and latency requirements on data frame transmission than the transmission performance currently defined by TID.

[0105] Here, a TID with a value greater than 7 may be defined. Data frames with a TID with a value greater than 7 may have higher requirements on reliability and delay than data frames with a TID with a value less than or equal to 7.

[0106] Before sending a data frame with a TID greater than 7, the data frame transmitter may select one or more transport connections from multiple transport connections for sending the data frame with a TID greater than 7. An ADDTS request frame is sent on each transport connection. The ADDTS request frame may be set with a TID greater than 7 to indicate that the transport connection is used to send data frames with a TID greater than 7. Transmission parameters in the ADDTS request frame may be configured based on QoS requirements for data frames with a TID greater than 7. The ADDTS request frame may carry transmission parameters for data frames with a TID greater than 7.

[0107] After receiving the ADDTS request frame including the TID with a value greater than 7, the data frame receiving end can determine the transmission parameters requested by the data frame sending end.

[0108] In this way, by transmitting an ADDTS request frame containing a TID with a value greater than 7, on the one hand, the ADDTS request and ADDTS response mechanisms are compatible with data frames with different TIDs. On the other hand, the ADDTS request frame can request transmission parameters of data frames with higher transmission requirements, so that the transmission of data frames can meet QoS transmission requirements and improve the reliability of data frame transmission.

[0109] In one embodiment, the first reserved bit of the service flow information TS info field of the service specification TSPEC field of the ADDTS request frame carries the TID whose value is greater than 7.

[0110] In the ADDTS request and ADDTS response mechanism, TSPEC is used to parameterize the QoS requirements of data frames. The ADDTS request characterizes the QoS requirements of data frames in the form of transmission parameters in the TSPEC field.

[0111] The format of the TSPEC field is as follows Figure 4 As shown, the format of the TS info field in the TSPEC field is as follows Figure 5 As shown, bits 17 to 23 of the TS info field are reserved bits.

[0112] The reserved bits in the TS info field may be used to set a TID with a value greater than 7. For example, one or more bits from bit 17 to bit 23 of the TS info field may be used to set a TID with a value greater than 7. The TID may be directly indicated by a value that is the same as the TID value, for example, binary "1001" may be used to directly indicate that the TID is 9. Different values ​​may also be used to represent different TIDs, for example, binary "00" may be used to represent a TID of 8, and binary "01" may be used to represent a TID of 9.

[0113] In this way, the reserved bit is used to indicate TIDs with a value greater than 7. On the one hand, the information content of the ADDTS request frame is improved, and the utilization efficiency of the ADDTS request frame is improved; on the other hand, the compatibility of the ADDTS request frame is improved. The ADDTS request frame can be configured with transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.

[0114] In one embodiment, the first reserved code of the access policy field of the TS info field of the TSPEC field of the ADDTS request frame carries indication information indicating the access policy of the data frame with a TID value greater than 7.

[0115] The access policy field is used to indicate the access policy used when transmitting data frames, such as Figure 6 As shown, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" is a reserved code, and "00" can be used to indicate the access policy adopted for data frame transmission with a TID value greater than 7.

[0116] The access policy used for transmitting data frames with TID values ​​greater than 7 may have a higher priority to meet the reliability and latency requirements of data frames with TID values ​​greater than 7.

[0117] In one embodiment, the second reserved code of the QoS Action field of the ADDTS request frame carries indication information indicating the QoS Action frame type of the ADDTS request frame.

[0118] The QoS Action field is used to indicate the QoS Action frame type of the ADDTS request frame. The wireless device can determine the action to be taken based on different QoS Action frame types.

[0119] like Figure 7As shown, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoSAction frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the QoS Action frame type of the ADDTS request frame with a value greater than 7.

[0120] In one embodiment, the method further comprises:

[0121] An add service flow ADDTS response frame is received, wherein the ADDTS response frame at least includes the service identifier TID whose value is greater than 7.

[0122] After receiving the ADDTS request frame including the TID with a value greater than 7, the data frame receiving end can determine the transmission parameters requested by the data frame sending end.

[0123] The data frame receiver may determine whether to accept the transmission parameters indicated by the ADDTS request frame based on the current load of the transmission connection and its own load. The transmission parameters may be modified based on the current load of the transmission connection and its own load, and used as the transmission parameters determined for transmitting data frames with TIDs greater than 7. The determined transmission parameters for transmitting data frames with TIDs greater than 7 are sent to the data frame transmitter via an ADDTS response frame.

[0124] The transmission parameters requested in the ADDTS request frame and the transmission parameters recommended in the ADDTS response frame may be the same or different.

[0125] After receiving the ADDTS response frame, the data frame may determine the transmission parameters for transmitting the data frame with a TID value greater than 7, and use the parameters to transmit the data frame with a TID value greater than 7.

[0126] In this way, an ADDTS request and ADDTS response mechanism is established for data frames with TID values ​​greater than 7, thereby ensuring QoS for transmission of data frames with TID values ​​greater than 7.

[0127] In one embodiment, the second reserved bit of the TS info field of the TSPEC field of the ADDTS response frame carries the TID whose value is greater than 7.

[0128] In the ADDTS request and ADDTS response mechanisms, TSPEC is used to parameterize the QoS requirements of data frames. The ADDTS request characterizes the QoS requirements of data frames in the form of transmission parameters in the TSPEC field. The ADDTS response characterizes the QoS requirements of the determined data frames in the form of transmission parameters in the TSPEC field.

[0129] The format of the TSPEC field is as follows Figure 4 As shown, the format of the TS info field in the TSPEC field is as follows Figure 5 As shown, bits 17 to 23 of the TS info field are reserved bits.

[0130] The reserved bits in the TS info field may be used to set a TID with a value greater than 7. For example, one or more bits from bit 17 to bit 23 of the TSinfo field may be used to set a TID with a value greater than 7. The TID may be directly indicated by a value that is the same as the TID value, for example, binary "1001" may be used to directly indicate that the TID is 9. Different values ​​may also be used to represent different TIDs, for example, binary "00" may be used to represent a TID of 8, and binary "01" may be used to represent a TID of 9, and so on.

[0131] In this way, the reserved bit is used to indicate TIDs with a value greater than 7. On the one hand, the information content of the ADDTS request frame is improved, and the utilization efficiency of the ADDTS request frame is improved; on the other hand, the compatibility of the ADDTS request frame is improved. The ADDTS request frame can be configured with transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.

[0132] In one embodiment, the third reserved code of the access policy field of the TS info field of the TSPEC field of the ADDTS response frame carries indication information indicating the access policy of the data frame with a TID value greater than 7.

[0133] The access policy field of the ADDTS response frame is used to indicate the access policy used when a certain data frame is transmitted, such as Figure 6 As shown, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" is a reserved code, and "00" can be used to indicate the access policy adopted for data frame transmission with a TID value greater than 7.

[0134] The access policy used for transmitting data frames with TID values ​​greater than 7 may have a higher priority to meet the reliability and latency requirements of data frames with TID values ​​greater than 7.

[0135] In one embodiment, the fourth reserved code of the QoS Action field of the ADDTS response frame carries indication information indicating the QoS Action frame type of the ADDTS response frame.

[0136] The QoS Action field is used to indicate the QoS Action frame type of the ADDTS response frame. The wireless device can determine the action to be taken based on different QoS Action frame types.

[0137] like Figure 7 As shown, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoSAction frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the QoS Action frame type of the ADDTS response frame with a value greater than 7.

[0138] In one embodiment, the method further comprises:

[0139] Determine, according to an instruction of the ADDTS response frame, a second transmission connection among the multiple transmission connections for transmitting the data frame corresponding to the TID having a value greater than 7, wherein the first transmission connection is the same as or different from the second transmission connection.

[0140] The ADDTS response frame may carry indication information indicating the second transport connection.

[0141] The data frame receiving end may determine the first transmission connection as the transmission connection for transmitting the data frame, or may select a second transmission connection that meets the transmission requirements of the data frame with a TID value greater than 7 based on the load status or latency of each transmission connection in the multiple transmission connections, and determine the second transmission connection as the transmission connection for transmitting the data frame with a TID value greater than 7.

[0142] The data frame sending end may determine the second transmission connection based on the indication information indicating the second transmission connection, and send the data frame in the second transmission connection.

[0143] When the data frame receiving end does not indicate the second transport connection, the data frame sending end may use the first transport connection to send several frames. In one embodiment, the third reserved bit of the TSPEC field of the ADDTS response frame carries indication information indicating the second transport connection.

[0144] The indication information indicating the second transport connection may be used to indicate a transport connection identifier of the second transport connection, etc. Reserving bits in the TSPEC field to carry the indication information indicating the second transport connection may improve the utilization efficiency of the TSPEC field.

[0145] In one embodiment, the method further comprises:

[0146] A transmission connection whose transmission status satisfies the transmission condition among the multiple transmission connections is determined as a first transmission connection for transmitting the data frame corresponding to the TID with a value greater than 7.

[0147] Data frames corresponding to TIDs with values ​​greater than 7 require higher reliability and lower latency.

[0148] Before sending the ADDTS request frame, the data frame transmitter may first select a first transmission connection that meets the data frame transmission condition with a TID value greater than 7 based on the load status or delay of each transmission connection among multiple transmission connections.

[0149] The data frame sender may send an ADDTS request frame on the first transmission connection selected for transmitting data frames with a TID value greater than 7.

[0150] In one embodiment, the transmission status includes: the load of the basic service set BSS, and / or the load of each transmission connection, and / or the access delay, and / or the transmission delay.

[0151] The data frame sending end may receive the beacon frame sent by the data frame receiving end, and the beacon frame may carry the transmission status of the transmission connection.

[0152] The load of a basic service set (BSS) indicates the number of stations within a specific BSS and the level of channel resource utilization. A lower BSS load improves data frame transmission reliability and reduces data frame transmission latency. The load of a transport connection indicates the level of channel resource utilization for that connection. A lower transport connection load improves data frame transmission reliability and reduces data frame transmission latency.

[0153] Lower access and transmission delays can reduce the latency of data frames throughout the transmission process. Access delay is the time it takes for the data frame transmitter to access and occupy the channel. Transmission delay can include transmission delay, transmission delay, processing delay, and data frame alignment delay.

[0154] Here, before sending the ADDTS request frame, the data frame transmitter may select a transmission connection whose transmission status meets the transmission conditions from among multiple transmission connections and determine it as the first transmission connection. If the transmission status of the transmission connection meets the transmission conditions, the transmission connection may be used to transmit data frames with a TID value greater than 7, thereby ensuring that the transmission of data frames with a TID value greater than 7 meets reliability and latency requirements.

[0155] like Figure 8 As shown, this exemplary embodiment provides an information transmission method, which can be applied to a data frame receiving end of wireless communication, including:

[0156] Step 801: In a first transmission connection among multiple transmission connections, an ADDTS request frame for adding a service stream is received, wherein the ADDTS request frame at least includes a service identifier TID with a value greater than 7.

[0157] Here, the data frame transmitter may be an access point (AP) or a station (STA) in a Wi-Fi communication system, and the data frame receiver may be an AP or a STA in the Wi-Fi communication system.

[0158] The data frame sender and the data frame receiver can establish one or more transmission connections in multiple frequency bands. The data frame sender can send data frames through a single transmission connection or send different data frames through multiple transmission connections.

[0159] Before sending a data frame, the data frame transmitter can send an ADDTS request frame to the data frame receiver, providing the receiver with transmission parameters for data frames with different TIDs, ensuring that the data frame transmission meets QoS requirements. Transmission parameters may include data rate, Media Access Control Service Data Unit (MSDU) bit count, etc. The data frame receiver can determine the final transmission parameters based on the transmission connection load and return the determined transmission parameters to the data frame transmitter via an ADDTS response frame.

[0160] In related art, in order to ensure QoS of data frame transmission, different TIDs are assigned to data frames according to the QoS requirements of different services, and the range of TIDs is 0 to 7. Different TIDs represent different QoS requirements.

[0161] The IEEE 802.11be standard proposes the requirement for highly reliable and low-latency data frames. This requirement places higher reliability and latency requirements on data frame transmission than the transmission performance currently defined by TID.

[0162] Here, a TID with a value greater than 7 may be defined. Data frames with a TID with a value greater than 7 may have higher requirements on reliability and delay than data frames with a TID with a value less than or equal to 7.

[0163] Before sending a data frame with a TID greater than 7, the data frame transmitter may select one or more transport connections from multiple transport connections for sending the data frame with a TID greater than 7. An ADDTS request frame is sent on each transport connection. The ADDTS request frame may be set with a TID greater than 7 to indicate that the transport connection is used to send data frames with a TID greater than 7. Transmission parameters in the ADDTS request frame may be configured based on QoS requirements for data frames with a TID greater than 7. The ADDTS request frame may carry transmission parameters for data frames with a TID greater than 7.

[0164] After receiving the ADDTS request frame including the TID with a value greater than 7, the data frame receiving end can determine the transmission parameters requested by the data frame sending end.

[0165] In this way, by transmitting an ADDTS request frame containing a TID with a value greater than 7, on the one hand, the ADDTS request and ADDTS response mechanisms are compatible with data frames with different TIDs. On the other hand, the ADDTS request frame can request transmission parameters of data frames with higher transmission requirements, so that the transmission of data frames can meet QoS transmission requirements and improve the reliability of data frame transmission.

[0166] In one embodiment, the first reserved bit of the service flow information TS info field of the service specification TSPEC field of the ADDTS request frame carries the TID whose value is greater than 7.

[0167] In the ADDTS request and ADDTS response mechanism, TSPEC is used to parameterize the QoS requirements of data frames. The ADDTS request characterizes the QoS requirements of data frames in the form of transmission parameters in the TSPEC field.

[0168] The format of the TSPEC field is as follows Figure 4 As shown, the format of the TS info field in the TSPEC field is as follows Figure 5 As shown, bits 17 to 23 of the TS info field are reserved bits.

[0169] The reserved bits in the TS info field may be used to set a TID with a value greater than 7. For example, one or more bits from bit 17 to bit 23 of the TS info field may be used to set a TID with a value greater than 7. The TID may be directly indicated by a value that is the same as the TID value, for example, binary "1001" may be used to directly indicate that the TID is 9. Different values ​​may also be used to represent different TIDs, for example, binary "00" may be used to represent a TID of 8, and binary "01" may be used to represent a TID of 9.

[0170] In this way, the reserved bit is used to indicate TIDs with a value greater than 7. On the one hand, the information content of the ADDTS request frame is improved, and the utilization efficiency of the ADDTS request frame is improved; on the other hand, the compatibility of the ADDTS request frame is improved. The ADDTS request frame can be configured with transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.

[0171] In one embodiment, the first reserved code of the access policy field of the TS info field of the TSPEC field of the ADDTS request frame carries indication information indicating the access policy of the data frame with a TID value greater than 7.

[0172] The access policy field is used to indicate the access policy used when transmitting data frames, such as Figure 6As shown, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" is a reserved code, and "00" can be used to indicate the access policy adopted for data frame transmission with a TID value greater than 7.

[0173] The access policy used for transmitting data frames with TID values ​​greater than 7 may have a higher priority to meet the reliability and latency requirements of data frames with TID values ​​greater than 7.

[0174] In one embodiment, the second reserved code of the QoS Action field of the ADDTS request frame carries indication information indicating the QoS Action frame type of the ADDTS request frame.

[0175] The QoS Action field is used to indicate the QoS Action frame type of the ADDTS request frame. The wireless device can determine the action to be taken based on different QoS Action frame types.

[0176] like Figure 7 As shown, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoSAction frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the QoS Action frame type of the ADDTS request frame with a value greater than 7.

[0177] In one embodiment, the method further comprises:

[0178] In response to the ADDTS request frame, an add service flow ADDTS response frame is sent, wherein the ADDTS response frame at least includes the service identifier TID with a value greater than 7.

[0179] After receiving the ADDTS request frame including the TID with a value greater than 7, the data frame receiving end can determine the transmission parameters requested by the data frame sending end.

[0180] The data frame receiver may determine whether to accept the transmission parameters indicated by the ADDTS request frame based on the current load of the transmission connection and its own load. The transmission parameters may be modified based on the current load of the transmission connection and its own load, and used as the transmission parameters determined for transmitting data frames with TIDs greater than 7. The determined transmission parameters for transmitting data frames with TIDs greater than 7 are sent to the data frame transmitter via an ADDTS response frame.

[0181] The transmission parameters requested in the ADDTS request frame and the transmission parameters recommended in the ADDTS response frame may be the same or different.

[0182] After receiving the ADDTS response frame, the data frame may determine the transmission parameters for transmitting the data frame with a TID value greater than 7, and use the parameters to transmit the data frame with a TID value greater than 7.

[0183] In this way, an ADDTS request and ADDTS response mechanism is established for data frames with TID values ​​greater than 7, thereby ensuring QoS for transmission of data frames with TID values ​​greater than 7.

[0184] In one embodiment, the second reserved bit of the TS info field of the TSPEC field of the ADDTS response frame carries the TID whose value is greater than 7.

[0185] In the ADDTS request and ADDTS response mechanisms, TSPEC is used to parameterize the QoS requirements of data frames. The ADDTS request characterizes the QoS requirements of data frames in the form of transmission parameters in the TSPEC field. The ADDTS response characterizes the QoS requirements of the determined data frames in the form of transmission parameters in the TSPEC field.

[0186] The format of the TSPEC field is as follows Figure 4 As shown, the format of the TS info field in the TSPEC field is as follows Figure 5 As shown, bits 17 to 23 of the TS info field are reserved bits.

[0187] The reserved bits in the TS info field may be used to set a TID with a value greater than 7. For example, one or more bits from bit 17 to bit 23 of the TSinfo field may be used to set a TID with a value greater than 7. The TID may be directly indicated by a value that is the same as the TID value, for example, binary "1001" may be used to directly indicate that the TID is 9. Different values ​​may also be used to represent different TIDs, for example, binary "00" may be used to represent a TID of 8, and binary "01" may be used to represent a TID of 9, and so on.

[0188] In this way, the reserved bit is used to indicate TIDs with a value greater than 7. On the one hand, the information content of the ADDTS request frame is improved, and the utilization efficiency of the ADDTS request frame is improved; on the other hand, the compatibility of the ADDTS request frame is improved. The ADDTS request frame can be configured with transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.

[0189] In one embodiment, the third reserved code of the access policy field of the TS info field of the TSPEC field of the ADDTS response frame carries indication information indicating the access policy of the data frame with a TID value greater than 7.

[0190] The access policy field of the ADDTS response frame is used to indicate the access policy used when a certain data frame is transmitted, such as Figure 6 As shown, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" is a reserved code, and "00" can be used to indicate the access policy adopted for data frame transmission with a TID value greater than 7.

[0191] The access policy used for transmitting data frames with TID values ​​greater than 7 may have a higher priority to meet the reliability and latency requirements of data frames with TID values ​​greater than 7.

[0192] In one embodiment, the fourth reserved code of the QoS Action field of the ADDTS response frame carries indication information indicating the QoS Action frame type of the ADDTS response frame.

[0193] The QoS Action field is used to indicate the QoS Action frame type of the ADDTS response frame. The wireless device can determine the action to be taken based on different QoS Action frame types.

[0194] like Figure 7 As shown, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoSAction frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the QoS Action frame type of the ADDTS response frame with a value greater than 7.

[0195] In one embodiment, the method further comprises:

[0196] Determine a second transmission connection among the multiple transmission connections for the data frame corresponding to the TID having a value greater than 7, wherein the first transmission connection is the same as or different from the second transmission connection.

[0197] The data frame receiving end may determine the first transmission connection as the transmission connection for transmitting the data frame, or may select a second transmission connection that meets the transmission requirements of the data frame with a TID value greater than 7 based on the load status or latency of each transmission connection in the multiple transmission connections, and determine the second transmission connection as the transmission connection for transmitting the data frame with a TID value greater than 7.

[0198] In one embodiment, sending an ADDTS response frame includes:

[0199] Sending the ADDTS response frame for indicating the second transport connection.

[0200] The data frame receiving end may indicate the second transport connection for sending the data frame in the ADDTS response frame.

[0201] In one embodiment, the third reserved bit of the TSPEC field of the ADDTS response frame carries indication information indicating the second transport connection.

[0202] The data frame sending end may determine the second transmission connection based on the indication information indicating the second transmission connection, and send the data frame in the second transmission connection.

[0203] When the data frame receiving end does not indicate the second transport connection, the data frame sending end may use the first transport connection to send several frames. In one embodiment, the third reserved bit of the TSPEC field of the ADDTS response frame carries indication information indicating the second transport connection.

[0204] The indication information indicating the second transport connection may be used to indicate a transport connection identifier of the second transport connection, etc. Reserving bits in the TSPEC field to carry the indication information indicating the second transport connection may improve the utilization efficiency of the TSPEC field.

[0205] In one embodiment, determining the second transmission connection among the multiple transmission connections for the data frame corresponding to the TID having a value greater than 7 includes:

[0206] A transmission connection whose transmission status satisfies the transmission condition among the multiple transmission connections is determined as a second transmission connection for transmitting the data frame corresponding to the TID with a value greater than 7.

[0207] Data frames corresponding to TIDs with values ​​greater than 7 require higher reliability and lower latency.

[0208] Before sending the ADDTS response frame, the data frame receiver may first select a second transmission connection that meets the data frame transmission condition with a TID value greater than 7 based on the load status or delay of each transmission connection in the multiple transmission connections.

[0209] The data frame sender may use the second transmission connection indicated in the ADDTS response frame to transmit the data frame.

[0210] In one embodiment, the transmission status includes:

[0211] The load of the basic service set BSS, and / or the load of each transmission connection, and / or the access delay, and / or the transmission delay.

[0212] The load of a basic service set (BSS) indicates the number of stations within a specific BSS and the level of channel resource utilization. A lower BSS load improves data frame transmission reliability and reduces data frame transmission latency. The load of a transport connection indicates the level of channel resource utilization for that connection. A lower transport connection load improves data frame transmission reliability and reduces data frame transmission latency.

[0213] Lower access and transmission delays can reduce the latency of data frames throughout the transmission process. Access delay is the time it takes for the data frame transmitter to access and occupy the channel. Transmission delay can include transmission delay, transmission delay, processing delay, and data frame alignment delay.

[0214] Here, before sending the ADDTS response frame, the data frame receiver may select a transmission connection from multiple transmission connections whose transmission status meets the transmission conditions and determine it as the second transmission connection. When the transmission status of the transmission connection meets the transmission conditions, the transmission connection may be used to transmit data frames with a TID value greater than 7, so that the transmission of data frames with a TID value greater than 7 meets the reliability and latency requirements.

[0215] The following provides a specific example in combination with any of the above embodiments:

[0219] Furthermore, if Figure 5 As shown, the reserved bits in the TS info field can be used to set the TID of the low-latency, high-reliability service, for example, using four of the bits and setting a value greater than 7.

[0220] 2. Encapsulation of TSPEC Information Elements

[0221] The information elements defined in 1 are encapsulated in the ADDTS request and ADDTS response frames, so it is a newly defined frame of the QoS action frame, such as Figure 7 As shown, the reserved encoding definition can be utilized.

[0222] 3. Device Behavior

[0223] Based on the BSS load and access delay information elements broadcast by the received beacon frame for each connection, the STA sends an ADDTS request frame on the connection with the best BSS load and access delay. The frame carries the TSPEC information element and sets the access policy based on the upper-layer data frame.

[0224] The AP replies with an ADDTS response frame, also carrying a TSPEC information element in the frame. The AP can recommend a connection for sending upper-layer data frames. The recommended connection can be identified by the reserved bit in the TSPEC frame. If no recommendation is made, the data frame is sent for the connection that received the ADDTS request frame.
