Description

Information transmission method, transmitting node and receiving node

technical field

The embodiments of the present invention relate to communication technologies, and in particular to an information transmission method, a transmitting node and a receiving node.

Background technique

In a wireless communication system, when a transmitting node communicates with a receiving node, it may be that the transmitting node and the receiving node perform information transmission on the same resource.

Therefore, before the transmitting node and the receiving node perform information transmission, the transmitting node needs to allocate resources to the receiving node, that is, allocate a resource to the receiving node, so that the transmitting node can perform information transmission with the receiving node on the resource. However, due to the different environment of each node, different nodes perceive the resource differently, so that the available resources of each node are different. That is to say, the transmitting node and the receiving node perceive the same resource differently.

Therefore, the resources allocated by the transmitting node to the receiving node may be available to the transmitting node, but may not be available to the receiving node, which makes the communication between the transmitting node and the receiving node unreliable, or even a communication failure occurs.

Wherein, the transmitting node may be, for example, an access point (Access Point, AP for short) or a station (Station, STA for short). If the transmitting node is an AP, then the receiving node is an STA; if the transmitting node is an STA, then the receiving node is an AP.

S101. The transmitting node determines a transmission resource for communicating with at least one receiving node; wherein, the transmission resource corresponding to each receiving node includes at least one resource.

Specifically, the transmitting node may determine, on an available channel of the transmitting node, a transmission resource for communicating with each receiving node of the at least one receiving node. The available channel of the transmitting node may be, for example, a channel selected by the transmitting node according to the transmission channel requirement of the transmitting node and the channel status of multiple channels of the current network. Each channel among the available channels of the transmitting node may be, for example, a channel corresponding to a current system bandwidth. For example, if the current bandwidth is 20M, each channel in the available channels of the transmitting node may be a channel with a bandwidth of 20M.

The transmission resource corresponding to each receiving node includes at least one resource, and the at least one resource may be, for example, a resource in an available channel of the transmitting node. That is to say, the at least one resource may be an available resource for the transmitting node.

Among the at least one resource included in the transmission resource corresponding to each receiving node, each resource may include a resource on a channel. The granularity of each resource may be, for example, the resource scheduling granularity of the transmitting node, such as a subcarrier, a subchannel, a resource unit (Resource Unit, RU for short), a resource block (Resource Block, RB for short), and the like.

S102. The transmitting node sends information to each receiving node, where the information on each of the transmission resources corresponding to each receiving node is the same.

The information on each of the transmission resources corresponding to each receiving node is the same, that is, the transmitting node sends information to each receiving node in a manner of copying and sending on each resource of the transmission resource corresponding to each receiving node.

In the information transmission method provided by Embodiment 1 of the present invention, the transmitting node determines the transmission resource for communicating with at least one receiving node, and the transmitting node sends information to each receiving node, wherein the transmission resource corresponding to each receiving node The information is the same on each resource in . Since each resource includes at least one resource, even if one resource in the at least one resource is unavailable to a receiving node, the receiving node can still receive other resources in the transmission resources corresponding to the transmitting node in the receiving node. This information is sent on the network, thus ensuring reliable communication between the transmitting node and the receiving node.

Further optionally, each receiving node in the receiving nodes may also combine information on multiple channels through a Maximal Ratio Combining (MRC for short) technology, so as to enhance the robustness of receiving.

Embodiment 2 of the present invention also provides an information transmission method. Optionally, the information includes resource indication information. The resource indication information, for example, may be indication information of the transmission resource, and may be used to indicate to each receiving node the transmission resource used by the transmitting node.

Each receiving node may determine according to the resource indication information that the information is sent by the transmitting node in a duplicate transmission manner on each resource of the transmission resource, that is, the information on each resource in the transmission resource is the same. Therefore, the resource indication information may also be referred to as transmission mode indication information.

Optionally, the resource indication information may be located in a preamble (Preamble), a service field (Service field), a medium access control (Medium Access Control, MAC for short) header or a data payload (DataPayload).

Specifically, the resource indication information may be located in a preamble, a service field, a MAC packet header or a data load in a wireless network frame sent by the transmitting node to each receiving node. FIG. 2 is a schematic diagram of a frame structure of a wireless network according to Embodiment 2 of the present invention. As shown in FIG. 2 , a wireless network frame mainly includes: a preamble, a service field, a MAC header, a data payload, and a Frame Check Sequence (FCS for short). If the resource indication information, it can be located in the idle or multiplexing field in the preamble, the idle or multiplexing field in the service field, the idle or multiplexing field in the MAC packet header, or the idle field in the data payload. It should be noted that the resource indication information may also be carried in a newly added field of the wireless network frame where the information is located, and details will not be described here.

The resource indication information may be represented by a bitmap of a field in the preamble, the service field, the MAC packet header or the data payload. If the current system includes at least one resource, each resource may correspond to a bit of a field, and the resource indication information may be represented by a bit value of at least one bit of the field. In the embodiment of the present invention, a bit value of 1 can be used to indicate that the resource corresponding to the bit has the same information that is copied and sent, and a bit value of 0 can be used to indicate that the resource corresponding to the bit has no copy This information was sent. Correspondingly, a bit value of 0 may indicate that the resource corresponding to the bit has the same information that is copied and sent, and a bit value of 1 may indicate that the resource corresponding to the bit does not have copy and sent information. the information. Alternatively, the resource indication information of one receiving node in the at least one receiving node may be represented by the one bit. The resource indication information of the one receiving node may be used to indicate whether the one receiving node duplicates and sends the same information on each resource. Specifically, the resource indication information of the receiving node can indicate that the receiving node has copied and sent the same information on each resource through a bit value of 1, and can indicate that the receiving node has not copied and sent the same information on each resource through a bit value of 0. information.

Each receiving node may determine the transmission resource used by the transmitting node for the information according to the bitmap corresponding to the resource indication information, and then determine that the transmitting node duplicates and sends the information on the transmission resource.

Optionally, the resource indication information may be located, for example, in the preamble, the service field, or a signaling field of the MAC packet header.

Optionally, the signaling field includes: a legacy signaling field (Legacy Signal Field, L-SIG for short) or a high-efficiency signaling field (High Efficient Signal Field, HE-SIG for short). The HE-SIG may include a high-efficiency signaling A field (High Efficient Signal Field A, HE-SIG-A for short) and/or a high-efficiency signaling B field (High Efficient Signal Field B, HE-SIG-B for short).

For example, Embodiment 2 of the present invention also provides another wireless network frame. FIG. 3 is a schematic diagram of another wireless network frame structure according to Embodiment 2 of the present invention. As shown in FIG. 3 , the wireless network frame may include: a preamble, a service field, a MAC frame, and a frame detection sequence. Wherein, the preamble may include a legacy short training field (Legacy Short Training Field, L-STF for short), a legacy long training field (Legacy Long Training Field, L-LTF for short), a legacy signaling field (Legacy Signal Field, L-SIG for short), ). Wherein, the MAC frame includes a MAC header and a data payload. The signaling field in which the resource indication information is located may be, for example, the L-SIG shown in FIG. 3 .

For example, if the information is downlink information, the signaling field where the resource indication information is located is a signaling field in a wireless network downlink frame. FIG. 4 is a schematic diagram of another wireless network downlink frame structure according to Embodiment 2 of the present invention. As shown in FIG. 4, the wireless network downlink frame may include a preamble, a service field, a MAC frame, and a frame detection sequence. Wherein, the preamble includes a traditional preamble and/or an efficient preamble. The legacy preamble may include L-STF, L-LTF, L-SIG and a repeated legacy signaling field (RepeatedLegacy Signal Field, RL-SIG for short). Wherein, the L-SIG can be used to ensure the backward compatibility of the receiving node in the system, so that the receiving node of the previous version standard can recognize the traditional preamble. The RL-SIG can be used to instruct the receiving node of the 802.11ax standard to perform automatic detection and enhance the robustness of the L-SIG. The efficient preamble may include: High Efficient Signal Field A (High Efficient Signal Field A, HE-SIG-A for short), High Efficient Signal Field B (High Efficient Signal Field B, HE-SIG-B for short), and High Efficient Short Training Field (High Efficient Short Training Field, HE-STF for short) and High Efficient Long Training Field (HE-LTF for short). Wherein, HE-SIG-A may be a domain indicating bandwidth, which is used to carry the indication information of the bandwidth of the receiving node. The HE-SIG-A information may include an identifier of the transmitting node, such as an AP identifier. The HE-SIG-B may be used to carry resource scheduling information of each receiving node in a Basic Service Set (BSS for short) where the transmitting node is located. The HE-STF and the HE-LTF are respectively used to carry information of automatic gain control (Automatic Gain Control, AGC for short) and channel measurement information for multiple input multiple output (Multiple Input Multiple Output, MIMO for short). The signaling field in which the resource indication information is located may include, for example, at least one field among L-SIG, HE-SIG-A, and HE-SIG-B shown in FIG. 4 .

It should be noted that the above-mentioned FIG. 3 and FIG. 4 are only for illustration, and the present invention is not limited thereto. That is to say, the signaling field in which the resource indication information is located may also be at least one other field in the frame structure of the wireless network, which will not be repeated here.

Optionally, the resource indication information is located in a Modulation and Coding Scheme (Modulation and Coding Scheme, MCS for short) field in the signaling field.

The resource indication information is represented by a preset MCS value in the MCS field. The preset MCS value corresponds to the MCS value of the modulation and coding scheme corresponding to the transmitting node.

For example, the preset MCS value may be, for example, corresponding to the MCS value of the modulation and coding scheme corresponding to the transmitting node, any other MCS value other than the used MCS value within the communication range where the transmitting node is located. If the MCS value used within the communication range where the transmitting node is located can be, for example, MCS0-MCS10, and the MCS value of the modulation and coding scheme corresponding to the transmitting node is MCS0, then the preset MCS value can be MCS11, and the MCS11 and the MCS0 Corresponding. Therefore, the resource indication information can be represented by MCS11 in the MCS field in the signaling field.

If the resource indication information may be, for example, the MCS domain located in the signaling field, the resource indication information may be located in the MCS domain in the HE-SIG-B.

Alternatively, the resource indication information may also be located in the field indicating the flow number in the signaling field, or in the field indicating the bandwidth in the signaling field.

For example, if the resource indication information is located in the field indicating the number of flows in the signaling field, the resource indication information may be located in the field indicating the number of flows in HE-SIG-B, and the field indicating the number of flows may be, for example, is the Number of Space-Time Stream (Number of Space-Time Stream, NSTS for short) field in the HE-SIG-B. If the resource indication information is located in the domain indicating the bandwidth in the signaling field, the resource indication information may be located in the domain indicating the bandwidth in the HE-SIG-A.

Optionally, the transmission resource corresponding to each receiving node may include: at least two resources.

Optionally, if the number of receiving nodes is multiple; the transmission resources corresponding to some receiving nodes in the multiple receiving nodes include: one resource; the transmission resources corresponding to other receiving nodes in the multiple receiving nodes include: at least two resources; wherein, the part of the receiving nodes and the other receiving nodes correspond to different priorities.

Specifically, the transmitting node can send the same information to the other receiving node on each of the transmission resources corresponding to the other receiving node, that is, send information to the other receiving node on each resource in a copy sending manner . For the part of receiving nodes, the transmitting node may directly send information on the one resource. The priority of this part of receiving nodes may be lower than that of other receiving nodes. In the embodiment of the present invention, the transmitting node only sends the same information to the other receiving node on each resource resource corresponding to the other receiving node in the receiving node, instead of sending all the receiving nodes in a duplicative manner information, while ensuring communication reliability, it can also improve resource utilization.

Optionally, the at least two transmission resources may include: at least two subchannels; each resource includes at least one subchannel. Wherein, one subchannel includes: one or more subcarriers.

Optionally, if the one subchannel includes: multiple subcarriers; the multiple subcarriers include at least one resource unit (Resource Unit, RU for short) subcarrier.

Optionally, the channels where the sub-channels of the at least two sub-channels are located are different.

Specifically, the channels where the sub-channels of the at least two sub-channels are located are different, that is, the at least two sub-channels are respectively located in at least two channels, wherein each channel has a sub-channel. Therefore, the transmitting node may, for example, send the information on the sub-channel corresponding to each receiving node on one channel, and send the same information on the sub-channel corresponding to each receiving node on other channels, that is, the channel is Units copy and send information. For example, if the current bandwidth is 20M, a channel may be a channel with a bandwidth of 20M.

For example, if the current system includes four channels, such as CH1, CH2, CH3, and CH4. If the transmitting node is an AP, the receiving node includes 3 nodes, such as STA1-STA3. Wherein, CH1 may be the main channel, and each channel may include: 3 sub-channels, such as Sub-CH1, Sub-CH2, and Sub-CH3. Each channel may include 9 RUs, and each subchannel may include subcarriers of 3 RUs. FIG. 5 is a schematic diagram of information transmission between a transmitting node and multiple receiving nodes in an information transmission method according to Embodiment 2 of the present invention. As shown in Figure 5, the transmission resources corresponding to STA1 may include: Sub-CH1 of each channel in CH1-CH4, the transmission resources corresponding to STA2 may include: Sub-CH2 of each channel in CH1-CH4, and the transmission resources corresponding to STA3 may be Including: Sub-CH3 of each channel in CH1~CH4. That is to say, the transmission resource corresponding to each node in STA1-STA3 includes 4 sub-channels, and each channel in CH1-CH4 has a sub-channel of each node. Therefore, the AP may, for example, send the same first information to the STA1 on the Sub-CH1 of each channel in CH1~CH4, and send the same second information to the STA2 on the Sub-CH2 of each channel, and send the same second information to the STA2 on each channel. Sub-CH3 sends the same third information to STA3.

Assuming that CH3 is not available to STA3, that is, STA3 may not be able to receive the third information sent by the AP on CH3. The third information sent by the AP is received on any one of CH2 and CH4. Further optionally, STA3 may also use MRC technology to combine information on multiple channels, so as to enhance the robustness of reception. Therefore, the information transmission method can ensure normal communication between the receiving node STA and the transmitting node AP, and can also improve the robustness of receiving.

Optionally, the channel where at least one subchannel of the at least two subchannels is located is the same as the channel where other subchannels are located.

That is, the at least two sub-channels may be located on at least two channels, wherein each channel has at least one sub-channel. Therefore, the transmitting node may, for example, send the information on one subchannel in the transmission resource corresponding to each receiving node, and send the same information on other subchannels, that is, copy and send the information in units of subchannels.

For example, if the current system includes four channels, such as CH1, CH2, CH3, and CH4. If the transmitting node is an AP, the receiving node includes 3 SATs, such as STA1-STA3. Wherein, CH1 may be the main channel, and each channel may include: 3 sub-channels, such as Sub-CH1, Sub-CH2, and Sub-CH3. Each channel may include 9 RUs, and each subchannel may include subcarriers of 3 RUs. FIG. 6 is a schematic diagram of information transmission between a transmitting node and multiple receiving nodes in another information transmission method provided by Embodiment 2 of the present invention. As shown in FIG. 6 , the transmission resources corresponding to STA1 may include: 5 sub-channels, such as Sub-CH1 and Sub-CH3 of CH1, Sub-CH1 of CH3, and Sub-CH1 and Sub-CH3 of CH4. The transmission resources corresponding to STA2 may include: 4 sub-channels, such as Sub-CH2 of CH1, Sub-CH1 and Sub-CH2 of CH2, and Sub-CH2 of CH4. The transmission resources corresponding to STA3 may include: 3 sub-channels, such as Sub-CH3 of CH2, Sub-CH2 and Sub-CH3 of CH3. Therefore, the AP can be, for example, Sub-CH1 and Sub-CH3 of CH1, Sub-CH1 of CH3, Sub-CH1 and Sub-CH3 of CH4 to send the same first information to the STA1. - Sub-CH1 and Sub-CH2 of CH2, Sub-CH2 of CH2, Sub-CH2 of CH4 send the same second information to STA2, Sub-CH3 of CH2, Sub-CH2 and Sub-CH3 of CH3 The channel sends the same third information to STA3.

Assuming that CH2 is not available for the STA3, that is, STA3 may not be able to receive the third information sent by the AP on CH2, as long as CH3 is available to STA3, the STA3 can receive the third information sent by the AP on CH3. information. Further optionally, STA3 may also use MRC technology to combine information on multiple channels, so as to enhance the robustness of reception. Therefore, the information transmission method can ensure normal communication between the receiving node STA and the transmitting node AP, and can also improve the robustness of receiving.

The information transmission method provided by Embodiment 2 of the present invention provides various implementation schemes of the information transmission method by providing the carrying positions of various resource indication information and various transmission resource structures, so as to better ensure the communication between the transmitting node and the receiving node. reliable communication.

FIG. 7 is a flow chart of an information transmission method provided by Embodiment 3 of the present invention. As shown in Figure 7, the information transmission method may include:

S701. The transmitting node sends a request frame to at least one receiving node; the request frame includes: transmission resource indication information corresponding to each receiving node; the transmission resource corresponding to each receiving node includes at least one resource.

Specifically, the transmitting node may send the request frame to the at least one receiving node on available resources of the transmitting node. The available resources of the transmitting node include: at least one resource. The transmitting node may send the request frame to the at least one receiving node on any resource in the at least one resource. Since the transmission channel requirements of different receiving nodes may be different, and the state of the at least one resource is different, in order to ensure that each receiving node can receive the request frame, the transmitting node can be the primary channel (Primary channel) in the at least one resource. channel), or, send the request frame to the at least one receiving node on each resource in the at least one resource. The transmitting node may, for example, send the request frame to the at least one receiving node in a broadcast or multicast manner.

The transmission resource corresponding to each receiving node may be, for example, the transmission resource for communicating with each receiving node determined on the available resources of the transmitting node, then at least one resource where the transmission resource corresponding to each receiving node is located The resource that may be an available resource of the transmitting node, that is, the at least one resource may be an available resource for the transmitting node.

The resource indication information of each receiving node may be used to indicate to each receiving node the transmission resource corresponding to each receiving node, and each receiving node may send to the transmitting node on the transmission resource corresponding to each receiving node response frame.

For example, if the current system includes 4 channels, CH1-CH4, then the transmitting node can perform resource allocation on any channel of CH1-CH4, and determine that the resource of each receiving node in the channel is the channel Sub-CH2, then the resource of each receiving node on other channels may be the Sub-CH2 of the other channel. FIG. 8 is a schematic diagram of information between a transmitting node and multiple receiving nodes in an information transmission method provided by Embodiment 3 of the present invention. As shown in Figure 8, the transmitting node may be an AP, and the receiving node may include 3 nodes, such as STA1-STA3, then the transmitting node AP may perform resource allocation on a channel such as CH1, and it is determined that STA1 in the receiving node is in The resource of the CH1 is Sub-CH1, the resource of STA2 in the CH1 is Sub-CH2, and the resource of STA3 in the CH1 is Sub-CH3. Use the same resource allocation on CH2 to CH4, and determine that the resources of STA1 on CH2 to CH4 are all Sub-CH1, the resources of STA2 on CH2 to CH4 are all Sub-CH2, and the resources of STA3 on CH2 to CH4 are all Sub-CH1. for Sub-CH3. That is to say, the transmission resources corresponding to STA1 may include: Sub-CH1 on CH1-CH4, the transmission resources corresponding to STA2 may include: Sub-CH2 on CH1-CH4, and the transmission resources corresponding to STA3 may include: CH1 ~Sub-CH3 on CH4.

Alternatively, the transmitting node may also perform resource allocation on some of the at least two channels, determine the resources of one channel of each receiving node in the part of the channels, and then assign resources to other channels in the at least two channels The same resource allocation is used on the channel to determine the resources of the other channels of each receiving node, thereby determining the at least one resource of each receiving node, that is, determining the transmission resource. FIG. 9 is a schematic diagram of information between a transmitting node and multiple receiving nodes in another information transmission method provided by Embodiment 3 of the present invention. As shown in Figure 9, the transmitting node can be an AP, and the receiving node can include 6 nodes, such as STA1-STA6, then the transmitting node AP can perform resource allocation on two channels such as CH1 and CH2, and determine that STA1 is in The resource of CH1 is Sub-CH1, the resource of STA2 in this CH1 is Sub-CH2, the resource of STA3 in this CH1 is Sub-CH3, the resource of STA4 in this CH2 is Sub-CH1, and the resource of STA5 in this CH2 is Sub - CH2, the resource of STA6 in this CH2 is Sub-CH3.

The transmitting node receives the same response frame sent by each receiving node on each available resource; each available resource includes: the available channel of each receiving node in the transmission resource corresponding to each receiving node each resource; the transmission resource corresponding to each receiving node is determined by each receiving node according to the transmission resource indication information corresponding to each receiving node.

Specifically, the available channel of each receiving node may be a channel selected by each receiving node according to the transmission channel requirement of each receiving node and the channel status of multiple channels of the current network.

For example, as shown in FIG. 8, the AP may send request frames to STA1-STA3 on CH1-CH4. The AP may receive the response frames sent by STA1-STA3 after a preset frame interval after sending the request frame. The preset frame interval may be, for example, X Inter-Frame Space (X Inter-Frame Space, XIFS for short). The frame interval can also be 0.

Even if CH2 is unavailable to STA3, the AP can accept the response frames sent by STA3 on CH1, CH3 and CH4.

As shown in FIG. 9, the AP may send request frames to STA1-STA6 on CH1-CH4. The AP may receive the response frames sent by STA1-STA6 after a preset frame interval after sending the request frame. The preset frame interval may be, for example, XIFS. The frame interval can also be 0. The AP can receive the response frame sent by STA1 on Sub-CH1 on CH1 and CH3, receive the response frame sent by STA2 on Sub-CH2 on CH1 and CH3, and send the response frame on Sub-CH3 on CH1 and CH3 by STA3 Response frame, receiving the response frame sent by STA4 on Sub-CH1 on CH2 and CH4, receiving the response frame sent by STA5 on Sub-CH2 on CH2 and CH4, and sending by STA6 on Sub-CH3 on CH2 and CH4 response frame.
