Embodiment 1

[0068] In this embodiment, it is only necessary for the receiver to detect the directional channel in the direction pointing to the transmitter, and judge whether the receiving environment of the channel directed from the transmitter to the receiver is available.

[0069] Such as Figure 5 As shown, a communication method of a directional communication system, comprising:

[0070] S10. The transmitter sends a request message.

[0071] In S10, the transmitter sends a request message to the receiver; as shown in the above application scenario, when TX2 and RX2 are communicating, TX1 wants to send data to RX1; before TX1 sends data to RX1, TX1 first sends data to RX1 A request message. In a specific implementation manner, the request message is a request to send an information RTS signal, that is, TX1 sends an RTS signal to RX1 first.

[0072] S11. The receiver receives the request message.

[0073] In S11, if RX1 can receive the request message sent by TX1 in S10, then RX1 ex...

Embodiment 2

[0086] In this embodiment, on the basis of Embodiment 1, the step of "the transmitter performs directional channel monitoring in the opposite direction to the direction of the receiver" is added, not only to judge whether the receiving environment of the channel directed by the transmitter to the receiver is available, but also It is necessary to judge whether the transmission environment of the channel directed from the transmitter to the receiver is available.

[0087] Figure 9 It is a schematic flow chart of Embodiment 2 of the present application.

[0088] Such as Figure 9 As shown, a communication method of a directional communication system, comprising:

[0089] S09. The transmitter performs directional channel detection in a direction opposite to the receiver, and if the detected channel is available, execute S10.

[0090] In S09, the transmitter performs directional channel detection in a direction opposite to the direction of the receiver, and detects whether the...

Embodiment 3

[0115] This embodiment describes the receiver, and it should be understood that the receiver described in this embodiment has any function of the receiver in the above method.

[0116] Figure 16 It is a schematic structural diagram of a receiver in this application.

[0117] Such as Figure 16 As shown, a receiver includes:

[0118] The receiver 10 is used to receive the request message.

[0119] Wherein, in a specific implementation manner, the request message is a request to send information RTS signal.

[0120] The receiver 10 is used for receiving data information.

[0121] Wherein, the receiver 10 is also used for receiving data information when the transmitter sends data information.

[0122] The processor 11 is configured to perform directional channel detection along the direction to the transmitter, and if the detected channel is available, trigger the transmitter 12 to send a response message, otherwise, do not trigger the transmitter 12 to send a response mess...

Abstract

The invention relates to the technical field of communication, and particularly to a communication method of a directional communication system and a receiver. The method comprises the steps of receiving a request message; performing directional channel monitoring along a direction pointing to a transmitter; if monitoring that the channel is usable, transmitting a response message; otherwise, nottransmitting any response message. According to the method, directional channel monitoring is carried out along the direction pointing to the transmitter after the receiver receives the request message, so whether the channel pointing to the receiver by the transmitter is available can be detected directionally and accurately, and problems of omitted or wrong detection in the prior art can be avoided.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method, a communication system and a receiver of a directional communication system. Background technique [0002] For high-frequency (such as 60GHz) communication systems, due to the rapid attenuation of the electromagnetic wave surface, in order to enhance the coverage and effectively suppress interference at the same time, the transmission of signals in the high-frequency communication system adopts directional sending and directional receiving technology, and the high-frequency communication system is directional One of the sending and receiving communication systems. [0003] In the above-mentioned directional communication system, different transceiver devices may interfere with each other when communicating. E.g, figure 1 It is a schematic diagram of mutual interference in a directional communication system; for example figure 1 As sh...
