Each responsive node need to return to second frame to node is initiated after receiving the first frame, every for this to realize The channel guard of a responsive node and the initiation node avoids other equipment from carrying out the transmission of information caused by channel competition dry It disturbs.

For each responsive node, which can be used single-input single-output (Single Input Single Output, SISO) mode to the initiation node returns to second frame.Each responsive node needle can be used in each responsive node Second frame is returned to the initiation node to the sending direction of the initiation node.Each responsive node can be used to be trained in advance Sending direction return to second frame to the initiation node.

For example, if the initiation node is located in the range of 1 place of sending direction of responsive node 1, it is located at response section In the range of where the sending direction 2 of point 2, in the range of 3 place of sending direction of responsive node 3, then responsive node 1 can Second frame is returned to the initiation node using sending direction 1, responsive node 2 can be used sending direction 2 and return to the initiation node Second frame is returned, responsive node 3 can be used sending direction 3 and return to second frame to the initiation node.

For the initiation node, this method may also include that

The second frame that S304, initiation node receive multiple responsive nodes while returning, the second of different responsive nodes returns Frame is identical.

Information transferring method provided by the embodiments of the present application can send first to multiple responsive nodes by initiating node Frame, and the second frame for receiving multiple responsive node while returning are realized for the initiation node and multiple response section Channel guard between point, wherein the second frame that different responsive nodes return is identical.Initiation node can receive multiple in this method The second frame that responsive node returns simultaneously, effectively shortens in multi-user transmission scene, initiates to carry out between node and responsive node The time of channel guard process improves network throughput, also, the second frame that different responsive nodes return is identical, effectively mentions Information robustness during high channel guard, also reduces and initiates the decoding complex degree that node is directed to the second frame, guarantee solution The accuracy of information after code.

Based on the above method, another information transferring method can also be provided in the application, in the another kind information In transmission method, the second frame that responsive node returns is received if initiating node and MIMO method can be used, different responsive nodes return The second frame can be identical, can also be different.

Optionally, as shown above it should be noted that the information transferring method is applicable to high frequency channel, that is, It says, in the information transferring method, initiates node and responsive node can be in the enterprising row information transmission of high frequency channel.Then in above-mentioned S301 It initiates node and sends first frame to multiple responsive nodes can include:

The first frame can be sent to multiple responsive nodes on high frequency channel by initiating node.

Thus, in above-mentioned S302 each responsive node can be received on high frequency channel initiate node send this first Frame.

Multiple responsive nodes send the second frame to initiation node simultaneously in above-mentioned S303 can include:

Multiple responsive nodes send the second frame to initiation node simultaneously on high frequency channel.

Thus, node can receive multiple responsive nodes while be returned on high frequency channel second is initiated in above-mentioned S304 Frame.

When the information transferring method is suitable for high frequency channel, then the initiation node can be realized by passing through the information transferring method With channel guard of multiple responsive node on high frequency channel.

High frequency channel is the channel that channel frequency is greater than predeterminated frequency, and predeterminated frequency for example can be 6GHz.

For example, high frequency channel as described above can be for example millimeter wave channel, such as 60GHz channel.Certainly, the height Frequency channel can also be the channel of other frequencies, above are only example, the application limits not to this.

The high frequency channel for example can be next generation 60GHz (Next Generation 60GHz, NG60) wireless local area It is involved in net, future 60GHz (Future Generation 60GHz, FG60) WLAN or other WLANs High frequency channel.Wherein, NG60 WLAN can for based on the institute's evolution of 802.11ad technology come 802.11ay technology WLAN, the NG60 wireless local area network technology can for based on low frequency channel technology such as 802.11n, 802.11ac, 802.11ax etc. and the wireless local area of the low-and high-frequency of the formation such as high frequency channel technology such as 802.11ad and 802.11ay mixing Net.
