Problems solved by technology

[0003] However, please refer to figure 1 , for device A and device C, simply adopting the physical carrier sensing mechanism, that is, judging the channel state through the energy detection of the physical layer, cannot detect that the other party is transmitting, thus causing device A and device C to receive device B's Collision occurs when signal
Especially for high frequency bands, due to the introduction of directional beams and directional listen before talk (Listen before talk) mechanism, the problem of device collision is more serious

Embodiment Construction

[0051] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0052] refer to figure 2 , figure 2 A wireless communication system 100 related to the present application is shown. The wireless communication system 100 can work in a licensed frequency band or an unlicensed frequency band. It can be understood that the use of unlicensed frequency bands can improve the system capacity of the wireless communication system 100 . Such as figure 2 As shown, the wireless communication system 100 includes: one or more network devices (only one is shown in the figure), such as gNB, eNodeB or WLAN access point, and one or more terminals (Terminals) 1-6. in:

[0053] The network device can be used to communicate with the terminals 1-6 under the control of a network device controller (such as a base station controller) (not shown). In some embodim...

Abstract

A signal interception method, related equipment and system, the method comprising: a sending device performs LBT; the sending device sends a first channel occupancy signal after the LBT is successful, and the first channel occupancy signal is used to report to the received The first receiving device of the first channel occupation signal indicates the channel occupation time to be protected on the channel occupied by the sending device after successful LBT. The solution provided by this application can be applied to systems such as V2X, LTE-V, V2V, Internet of Vehicles, MTC, IoT, LTE-M, M2M, Internet of Things, etc., which can avoid collisions between devices that need to be transmitted and improve communication efficiency.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a signal interception method applied to an unlicensed frequency band, related equipment and a system. Background technique [0002] Currently, in the LAA / eLAA system, physical carrier sensing is used to determine whether the channel is busy. Specifically, before data transmission, the sending device needs to listen to the channel. When the channel is idle and the corresponding backoff process is completed, the sending device obtains a corresponding maximum channel occupancy time (maximum channel occupancy time, MCOT), and data can be sent within this time. [0003] However, please refer to figure 1 , for device A and device C, simply adopting the physical carrier sensing mechanism, that is, judging the channel state through the energy detection of the physical layer, cannot detect that the other party is transmitting, thus causing device A and devic...
