Embodiment Construction

[0092] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0093] figure 1 A schematic diagram of a data transmission scenario provided by an embodiment of the present invention, such as figure 1As shown, the NRU communication device 01 can transmit data on a channel corresponding to a small bandwidth of 60 GHz (such as a bandwidth of 200 MHz); the 802.11ad communication device 11 can transmit data on a channel corresponding to a large bandwidth of 60 GHz (such as a bandwidth of 2.16 GHz); The 802.11ay communication device 21 can transmit data on a large bandwidth corresponding to 60 GHz (such as a bandwidth of 2.16 GHz). In practical applications, the bandwidth of the channel through which the NRU communication device 01 transmits data may also be other bandwidths less than 2.16 GHz, which i...

Abstract

The invention discloses a data transmission method, device and system, and belongs to the field of communication. The method comprises the following steps: the communication device determines an initial channel set, wherein the initial channel set comprises all currently accessible channels of the communication device; then the communication device performs primary idle channel evaluation CCA detection of all channels in the initial channel set, and determines the channel in which the initial CCA detection result is idle in the initial channel set as a target channel; and performing auxiliaryCCA detection on a preset channel, exemplarily, each channel in the initial channel set is a sub-channel of the preset channel; and if the auxiliary CCA detection is idle, the communication device transmits target data on the target channel. By adoption of the data transmission method, device and system, the problem that the NRU communication device is not compatible with the 802.11 communicationdevice is solved, the mutual compatibility between the NRU communication device and the 802.11 communication device is achieved, and the data transmission method, device and system are applied to datatransmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method, device and system. Background technique [0002] In communication standard 802.11 (including communication standard 802.11ad and communication standard 802.11ay), a device can transmit data on a channel with a corresponding frequency of 60 gigahertz (English: GHz). [0003] For example, when an 802.11 communication device needs to transmit data, the 802.11 communication device first needs to determine multiple channels that are currently accessible, and then determine a target channel that can currently transmit data among the multiple currently accessible channels, and then Data is transmitted on the target channel. Specifically, when the sender is currently on the target channel that can transmit data, it can first randomly determine the number of time slots of each channel among the multiple channels that are currently accessible, and according to...
