By means of the uplink multi-user transmission response method in the embodiments of the present invention, an access point can acknowledge, by only sending one acknowledgement message, a plurality of stations that the sent data is received successfully, so that the sending efficiency of the acknowledgement message is improved; and at the same time, the acknowledgement message carries a multicast address, so that the station can recognize whether the acknowledgement message contains acknowledgement information about the station more quickly, and thus the station unrelated to the acknowledgement message can discard the acknowledgement message quickly, which reduces the power consumption of the station.

Description

Uplink multi-user transmission response method, device and device

Technical field

The embodiments of the present invention relate to a wireless communication technology, and in particular, to an uplink multi-user transmission response method, apparatus, and device.

Background technique

Wireless Fidelity (WiFi) is a wireless LAN technology based on the IEEE 802.11 standard of the Institute of Electrical and Electronics Engineers (IEEE), which enables personal computers (Personal Computers, PCs) and users. Terminals such as User Equipment (UE) form a computer network in a wireless manner. The WiFi network consists of an Access Point (AP) and a User Site (Station: STA).

In the future-oriented high-density scenario, the IEEE intends to establish a new generation of IEEE802.11 supplementary standard, which will introduce OFDMA (Orthogonal Frequency-Division Multiple Access) technology. The OFDMA technology can improve the efficiency of bandwidth resource utilization. It divides the transmission bandwidth into orthogonal sets of subcarriers that do not overlap each other, and allocates different subcarrier sets to different sites. Sites communicate.

Multiple sites can simultaneously transmit data to the access point based on OFDMA technology. After the access point successfully receives the data, the access point needs to send an acknowledgement message (ACK) to multiple sites to confirm that the data it has sent has been Was successfully received. The current IEEE 802.11 standard only defines a single-site acknowledgment message, that is, a acknowledgment message can only answer one site. Then, the access point needs to send an acknowledgement message to multiple sites separately, and the acknowledgement message is sent inefficiently.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The method provided by the embodiment of the present invention is applied to a wireless system, and the main application scenario is: in a basic service set (BSS), that is, a network composed of one access point and multiple sites, the first access point A trigger message is sent to trigger an upstream multi-user message. Multiple sites simultaneously send uplink multi-user messages based on the trigger message. The access point simultaneously receives uplink multi-user messages sent by multiple sites, and then sends an acknowledgement message to multiple sites for responding to the receiving status of the messages sent by the multiple sites. The site receives and parses the acknowledgment message to determine the status of the received message that it sent in the past.

FIG. 1 is a flowchart of Embodiment 1 of an uplink multi-user transmission response method according to the present invention. In this embodiment, an execution entity is an access point. As shown in FIG. 1, the method in this embodiment may include:

Step 101: Send a trigger message, where the trigger message is used to trigger at least two stations to separately send an uplink message.

In this step, the access point sends a trigger message to trigger at least two stations to send an uplink message.

Step 102: Receive an uplink message.

In this step, the access point receives the uplink message sent by the station.

Step 103: Send an acknowledgement message corresponding to the uplink message, where the acknowledgement message includes the acknowledgement information of the uplink message and the multicast address, where the multicast address is an address corresponding to the site group composed of at least two sites or The address assigned to the site group that receives the acknowledgment message.

In this step, the access point sends an acknowledgement message to feed back the reception of the uplink message. The confirmation message includes an acknowledgement message for the uplink message and an address corresponding to the site group composed of multiple sites, that is, a multicast address, which is a dedicated address assigned to the site group receiving the acknowledgement message. Among them, a multicast address is a special type of address that points to a specific number of sites.

In this embodiment, the acknowledgement message sent by the foregoing may be an acknowledgement frame, for example, FIG. 2 is a schematic diagram of a possible frame structure of the acknowledgement frame. As shown in FIG. 2, the acknowledgement frame includes a frame control (Frame Control) field, and the receiver A Receiver Address (RA) field, a BA Content field, etc., where the RA field is used by the station to quickly identify whether the frame is parsed.

In the uplink multi-user transmission response method of the embodiment, the access point triggers the station to send an uplink message by sending a trigger message, and receives an uplink message sent by the station, and then sends an acknowledgement message, where the acknowledgement message includes the acknowledgement information of the uplink message and the acknowledgement message. The multicast address corresponding to the site group consisting of the sites enables the access point to send only one acknowledgment message, and can confirm to the multiple sites that the data sent by the site is successfully received, thereby improving the efficiency of sending the acknowledgment message. At the same time, by confirming that the message carries the multicast address, the site can more quickly identify whether the acknowledgment message contains its own acknowledgment information, so that the site irrelevant to the acknowledgment message can quickly discard the acknowledgment message and reduce the power consumption of the site.

Optionally, before the sending the acknowledgement message, the method further includes: sending a first notification message, where the first notification message includes the multicast address.

Optionally, the first notification message is an association response message or a beacon message.

Optionally, the trigger message further includes the multicast address.

Specifically, before the acknowledgment message is sent, the first notification message is further sent, where the first notification message includes the multicast address, and the first notification message may be an association response message or a beacon message, that is, access The point can inform the site of the multicast address by associating a response message or a beacon message. Or the trigger message further includes a multicast address, that is, the access point informs the site of the multicast address by using a trigger message.

Optionally, the multicast address includes a first part and a second part.

Optionally, the first portion is determined according to the beacon message or a partial field of the association response message. Specifically, the fixed part of the multicast address may also be generated by selecting a partial field of the beacon message or the associated response message.

Optionally, the trigger message includes the second part. The second portion is determined based on a partial field of the trigger message. Specifically, the variable part of the multicast address is included in the trigger message. The trigger message tells the site. Or the variable part can also select part of the field generation of the trigger message.

Optionally, before the sending the acknowledgement message, the method further includes: sending a second notification message, where the second notification message includes the first part of the multicast address. The second notification message is an association response message or a beacon message. Specifically, the fixed part of the multicast address may also notify the station by sending a second notification message before sending the acknowledgement message, where the second notification message includes a fixed part of the multicast address, and the second notification message may be an association response message or a letter. Standard message.

Specifically, in this embodiment, the foregoing multicast address is divided into two parts, a first part and a second part. The first part is a fixed part of the multicast address in this embodiment, and the second part is a multicast address in this embodiment. The variable part. The methods for generating and distributing the fixed portion and the variable portion of the multicast address can be classified into the following three categories. In the first type, the access point separately generates a fixed part and a variable part of the multicast address by using a random or preset method, and carries the fixed part of the multicast address in the beacon frame or the associated response frame, and carries in the trigger frame. A variable portion of the multicast address; the station receives the beacon frame or the associated response frame, and learns the fixed portion of the multicast address, and receives the trigger frame and learns the variable portion of the multicast address. In the second category, the access point determines a fixed portion of the multicast address according to a partial field of the beacon frame or the associated response frame. For example, the BSS Color and the MAC address of the access point are usually included in the beacon frame or the associated response frame. The ingress point may select a part of the MAC address of the access point to generate a fixed part of the multicast address, or generate a fixed part by a hash operation based on the BSS Color, since the method for generating the fixed part and the input information thereof are all access points. It is well known to the site, so the access point does not need to distribute a fixed part to the site; the access point generates a variable part of the multicast address by a random or preset method, and carries the variable part of the multicast address through the trigger frame; Since the method of generating the fixed part and the input information are all known to the access point and the station, the station can generate a fixed part of the multicast address, and obtain the variable part of the multicast address by receiving the trigger frame. In the third category, the access point determines the fixed part of the multicast address according to the partial field of the beacon frame or the associated response frame, and determines the variable part of the multicast address according to the partial field of the trigger frame, due to the generation of the fixed and variable parts. The method and its input information are all known to the access point and the site, so the access point does not need to distribute the fixed and variable parts to the site; the station determines the fixed part of the multicast address according to the partial field of the beacon frame or the associated response frame. And determining a variable portion of the multicast address according to a part of the field of the trigger frame; more specifically, a multicast address is composed of 6 bytes, and the first byte is preset according to an address rule of IEEE802.11, in order to distinguish The multicast address of the adjacent BSS, the second byte can be generated by the BSS Color or the MAC address of the access point, and the third to fifth bytes can be verified by the trigger frame (FCS) field or duration (Duration) Field generation, The generation method may be generated directly by selecting a partial bit of the above field, or by a partial budget bit of the above field by a specific budget method (for example, a hash operation).

The complete address of the site multicast address is informed by the generation and distribution of the fixed part and the variable part described above.

This message is the first message in the sequence of message interactions.

This embodiment will add a follow-up indication field to the trigger message. The follow-up indication field is used to indicate whether the message has an association with the previous message. Specifically, setting the follow-up indication field to a first value, for example, 0, indicating that the message is the first message of the message interaction sequence, that is, when the following indication field is 0, indicating that the current message is not associated with the previous message. contact. The first value here can also be set to other values as long as it can identify the interaction between messages.

Step 202: Receive an uplink message, where the uplink message includes a follow-up indication field, and the value of the follow-up indication field is a second value.

In this step, the station receives the trigger message and sends an uplink message.

Step 303: Receive an acknowledgement message corresponding to the uplink message, where the acknowledgement message includes the acknowledgement information of the uplink message and the multicast address, where the multicast address is an address corresponding to the site group composed of at least two sites or an address of the site group allocated to receive the acknowledgement message. .

In this step, the station receives an acknowledgement message to feed back the reception status of the uplink message to the access point. The confirmation message includes the acknowledgement information of the uplink message and an address corresponding to the site group composed of multiple sites, that is, a multicast address, which is a dedicated address assigned to the site group receiving the acknowledgement message. Among them, a multicast address is a special type of address that points to a specific number of sites.

In the uplink multi-user transmission response method of the embodiment, the station receives the trigger message and sends the uplink message, and then receives the acknowledgement message sent by the access point, and the acknowledgement message includes the uplink message. The multicast address corresponding to the information group and the site group composed of multiple sites enables multiple sites to confirm that the transmitted data is successfully received through an acknowledgement message, thereby improving the efficiency of sending the acknowledgement message. At the same time, by confirming that the message contains a multicast address, the site can more quickly identify whether the acknowledgment message contains its own acknowledgment information, so that the site irrelevant to the acknowledgment message can quickly discard the acknowledgment message and reduce the site power consumption.

Optionally, before receiving the acknowledgement message, the method further includes: receiving a first notification message, where the first notification message includes the multicast address.

The methods for generating and distributing the fixed portion and the variable portion of the multicast address can be classified into the following three categories. In the first category, the access point generates a multicast address by random or preset methods. a fixed part and a variable part, and carrying a fixed part of the multicast address in the beacon frame or the associated response frame, and carrying the variable part of the multicast address in the trigger frame; the station receives the beacon frame or the associated response frame, and learns A fixed portion of the multicast address, and a variable portion that receives the trigger frame and learns the multicast address. In the second category, the access point determines a fixed portion of the multicast address according to a partial field of the beacon frame or the associated response frame. For example, the BSS Color and the MAC address of the access point are usually included in the beacon frame or the associated response frame. The ingress point may select a part of the MAC address of the access point to generate a fixed part of the multicast address, or generate a fixed part by a hash operation based on the BSS Color, since the method for generating the fixed part and the input information thereof are all access points. It is well known to the site, so the access point does not need to distribute a fixed part to the site; the access point generates a variable part of the multicast address by a random or preset method, and carries the variable part of the multicast address through the trigger frame; Since the method of generating the fixed part and the input information are all known to the access point and the station, the station can generate a fixed part of the multicast address, and obtain the variable part of the multicast address by receiving the trigger frame. In the third category, the access point determines the fixed part of the multicast address according to the partial field of the beacon frame or the associated response frame, and determines the variable part of the multicast address according to the partial field of the trigger frame, due to the generation of the fixed and variable parts. The method and its input information are all known to the access point and the site, so the access point does not need to distribute the fixed and variable parts to the site; the station determines the fixed part of the multicast address according to the partial field of the beacon frame or the associated response frame. And determining a variable portion of the multicast address according to a part of the field of the trigger frame; more specifically, a multicast address is composed of 6 bytes, and the first byte is preset according to an address rule of IEEE802.11, in order to distinguish The multicast address of the adjacent BSS, the second byte can be generated by the BSS Color or the MAC address of the access point, and the third to fifth bytes can be verified by the trigger frame (FCS) field or duration (Duration) The field generation, the generation method may be directly generated by selecting a partial bit of the above field, or generated by a specific budget method (for example, a hash operation) by using a partial bit of the above field.

Through the generation and distribution of the fixed part and the variable part described above, the station can know the complete address of the multicast address.
