For example, 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 without departing from the scope of the embodiments of the present disclosure. Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determining."

The executive bodies involved in the embodiments of the present disclosure include but are not limited to: wireless communication networks, especially Wi-Fi networks, such as under the IEEE802.11a/b/g/n/ac standard, and the next-generation Wi-Fi network under the IEEE802.11be standard The network equipment, where the network equipment includes but is not limited to: wireless (AP, Access Point) access point equipment such as Wi-Fi routers, wireless stations (STA, Station), user terminals, user nodes, mobile terminals or tablet computers, etc. .

An application scenario of the embodiment of the present disclosure is that, during data frame transmission, in order to ensure the quality of service (QoS, Quality of Service) of the data frame transmission, a service identifier (TID, Traffic Identifier) is allocated to the data frame. When the TID is set to From 0 to 7, the identification data frame is based on the enhanced distributed channel access (EDCA, enhanced distributed channel Access) access strategy. The larger the number, the better the QoS needs to be guaranteed.

In the vision proposed by IEEE802.11be, a mechanism for adding traffic stream (ADDTS, Add Traffic stream) request and ADDTS response is introduced into the existing standard. The ADDTS request and ADDTS response mechanisms are used by both parties to negotiate transmission parameters for different TID data frames. The ADDTS request frame variable action field format is shown in Figure 1, and the ADDTS response frame variable action field format is shown in Figure 2.

The IEEE802.11be standard supports multi-transmission connection communication, and requires high reliability and low latency for data frames. The existing DECA mechanism cannot meet the requirements of multi-connection transmission and high reliability and low latency data frames.

As shown in FIG. 3 , this exemplary embodiment provides an information transmission method, and the information transmission method can be applied to a data frame transmitter of wireless communication, including:

Step 301: In a first transmission connection among the plurality of transmission connections, send an ADDTS request frame for adding a service flow, wherein the ADDTS request frame at least includes a service identifier TID whose value is greater than 7.

Here, the data frame sender may be an access point (AP, Access Point) or a station (STA, Station) in the Wi-Fi communication system. The receiving end of the data frame may be an AP or a STA in a Wi-Fi communication system.

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 can send different data frames through multiple transmission connections.

Before sending the data frame, the data frame sending end can send the ADDTS request frame to the data frame receiving end, and send the transmission parameters of different TID data frames to the data frame receiving end, so that the data frame transmission can meet the QoS requirements. The transmission parameters may include: data rate, medium access control service data unit (MSDU, MAC Service Data Unit) bit number, and the like. The data frame receiving end can determine the final transmission parameters according to the transmission connection load, etc., and return the recommended transmission parameters to the data frame sending end through the ADDTS response frame.

In the related art, in order to ensure the QoS of data frame transmission, different TIDs are allocated to the data frames according to the QoS requirements of different services, and the TID ranges from 0 to 7. Different TIDs represent different QoS requirements.

In the IEEE802.11be standard, the requirement of high reliability and low delay data frame is proposed. In addition, the requirements for the reliability and delay of data frame transmission are higher than the transmission performance defined by the current TID.

Here, a TID with a value greater than 7 can be defined, and a data frame with a TID with a value greater than 7 may have higher requirements on reliability and delay than a data frame with a TID with a value less than or equal to 7.

Before sending a data frame with a TID whose value is greater than 7, the data frame sender may select one or more transport connections from multiple transport connections for sending a data frame with a TID whose value is greater than 7. An ADDTS request frame is sent in each transport connection. A TID with a value greater than 7 can be set in the ADDTS request frame, which is used to indicate that the transmission connection is used to send a data frame with a TID with a value greater than 7. The transmission parameters in the ADDTS request frame can be configured according to the QoS requirements of the data frame with a TID whose value is greater than 7. The ADDTS request frame may carry the transmission parameters of the data frame with a TID whose value is greater than 7.

After receiving the ADDTS request frame containing the TID whose value is greater than 7, the data frame receiving end can determine the transmission parameters requested by the data frame sending end.

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 made compatible with data frames with different TIDs, and on the other hand, the ADDTS request frame can request higher transmission requirements The request for the transmission parameters of the data frame enables the transmission of the data frame to meet the QoS transmission requirements and improves the transmission reliability of the data frame.

In the ADDTS request and ADDTS response mechanisms, TSPEC is used to parameterize the QoS requirements of the data frame, and the ADDTS request represents the QoS requirements of the data frame in the form of transmission parameters in the TSPEC field.

The format of the TSPEC field is shown in Figure 4, and the format of the TS info field in the TSPEC field is shown in Figure 5. Bits 17 to 23 of the TS info field are reserved bits.

The reserved bits in the TS info field can be used to set a TID with a value greater than 7. For example, one or more bits in bits 17 to 23 of the TS info field can be used to set a TID with a value greater than 7; Directly use the same value as the TID value to indicate TID, for example, use binary "1001" to directly indicate that TID is 9, or use different values to represent different TIDs, such as binary "00" to indicate TID is 8, and binary "00" to indicate TID is 8. 01" TID is 9 etc.

In this way, the use of reserved bits as the TID indicating the value greater than 7 improves the information content of the ADDTS request frame and improves the utilization efficiency of the ADDTS request frame; on the other hand, improves the compatibility of the ADDTS request frame, and the ADDTS request frame can be configured Transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.

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 of the TID whose value is greater than 7.

The access policy field is used to indicate the access policy used during data frame transmission. As shown in Figure 6, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" is reserved code, "00" may be used to indicate the access policy adopted for the data frame transmission of the TID whose value is greater than 7.

The access policy adopted for the transmission of the data frame of the TID whose value is greater than 7 may have a higher priority, so as to meet the reliability and delay requirements of the data frame of the TID whose value is greater than 7.

The QoS Action field is used to indicate the QoS Action frame type of the ADDTS request frame, and the wireless device can determine the action to take according to different QoS Action frame types.

As shown in Figure 7, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoS Action frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the value QoS Action frame type for ADDTS request frames greater than 7.

In one embodiment, the method further includes:

The data frame receiving end 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 and the like can be modified in combination with the current load of the transmission connection and the own load, etc., as the determined transmission parameters for transmitting the data frame of the TID whose value is greater than 7. and send the determined transmission parameters for transmitting the data frame of the TID whose value is greater than 7 to the data frame sender through the ADDTS response frame.

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.

After the data frame receives the ADDTS response frame, the transmission parameters for transmitting the data frame of the TID whose value is greater than 7 can be determined. And use this parameter to transmit the data frame of TID whose value is greater than 7.

In this way, an ADDTS request and an ADDTS response mechanism are established for data frames with a TID whose value is greater than 7, to ensure the QoS of data frame transmission with a TID whose value is greater than 7.

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

A TID with a value greater than 7 can be set by using the reserved bits in the TS info domain, for example, one or more bits in bits 17 to 23 of the TS info domain can be used to set a TID with a numerical value greater than 7; You can directly use the same value as the TID value to indicate the TID, for example, use binary "1001" to directly indicate that the TID is 9, or you can use different values to represent different TIDs, such as binary "00". "01" TID is 9 and so on.

The access policy field of the ADDTS response frame is used to indicate the access policy used when the determined data frame is transmitted. As shown in Figure 6, the access policy field occupies two bits, and different codes are used to indicate different access policies. Here, the code "00" ” is reserved code, and “00” can be used to indicate the access policy adopted for data frame transmission of TID whose value is greater than 7.

The QoS Action field is used to indicate the QoS Action frame type of the ADDTS response frame, and the wireless device can determine the action to take according to different QoS Action frame types.

As shown in Figure 7, the QoS Action field occupies multiple bits, and 256 codes can be used to indicate different QoS Action frame types. Here, codes 7 to 255 are reserved codes, and any code from 7 to 255 can be used to indicate the value QoS Action frame type for ADDTS response frames greater than 7.

In one embodiment, the method further includes:

The ADDTS response frame may carry indication information indicating the second transmission connection.

The receiving end of the data frame may determine that the first transmission connection is the transmission connection for transmitting the data frame, and may also select the data frame that conforms to the TID whose value is greater than 7 based on the load condition or delay of each transmission connection in the multiple transmission connections. For the second transmission connection required for transmission, the second transmission connection is determined as a transmission connection for transmitting data frames with a TID whose value is greater than 7.

The data frame sender 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.

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

The indication information indicating the second transmission connection may be used to indicate the transmission connection identifier of the second transmission connection, and the like. The reserved bits in the TSPEC field carry the indication information indicating the second transmission connection, which can improve the utilization efficiency of the TSPEC field.

In one embodiment, the method further includes:

Since the data frame corresponding to a TID with a value greater than 7 requires higher reliability and lower delay.

Before sending the ADDTS request frame, the data frame sender may first select the first transmission connection that meets the data frame transmission conditions of the TID with a value greater than 7 based on the load condition or delay of each transmission connection in the multiple transmission connections.

The data frame sender may send the ADDTS request frame on the first transmission connection selected for transmitting the data frame with the TID value greater than 7.

In one embodiment, the transmission conditions include: 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.

The data frame sending end can receive the beacon frame sent by the data frame receiving end, and the beacon frame can carry the transmission status of the transmission connection.

The load of the basic service set BSS may indicate the number of stations in a particular BSS and the usage level of channel resources. A BSS with a lower load is beneficial to improve the reliability of data frame transmission and reduce the data frame transmission delay. The load of a transport connection may indicate the level of usage of channel resources for that transport connection. A lower transmission connection load is beneficial to improve the reliability of data frame transmission and reduce the data frame transmission delay.

The lower access delay and transmission delay can reduce the delay of the data frame in the entire transmission process. The access delay can be the time required for the data frame sender to access and occupy the channel. The transmission delay can indicate the transmission delay, transmission delay, processing delay, and data frame alignment delay during the transmission process of the data frame.

Here, before sending the ADDTS request frame, the data frame sender may select a transmission connection whose transmission condition satisfies the transmission condition among the multiple transmission connections, and determine it as the first transmission connection. When the transmission status of the transmission connection satisfies the transmission conditions, the transmission connection can be used to transmit data frames with a TID value greater than 7, so that the data frames with a TID value greater than 7 meet the reliability and delay requirements.

The transmission parameters may include: data rate, medium access control service data unit (MSDU, MAC Service Data Unit) bit number, and the like. The data frame receiving end can determine the final transmission parameters according to the transmission connection load, etc., and return the determined transmission parameters to the data frame sending end through the ADDTS response frame.

In one embodiment, the method further includes:

In this way, the use of reserved bits as a TID indicating a value greater than 7 improves the information content of the ADDTS request frame and improves the utilization efficiency of the ADDTS request frame; on the other hand, improves the compatibility of the ADDTS request frame, and the ADDTS request frame can be configured Transmission parameters corresponding to TIDs with a value less than or equal to 7 and TIDs with a value greater than 7.
