Embodiment 1

[0125] According to an embodiment of the present invention, a method for accessing an unlicensed spectrum is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0126] figure 1 It is a flow chart of the access method of the unlicensed spectrum in Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes the following steps:

[0127] S101. The transmission node determines according to preset conditions: the access mode of the unlicensed spectrum and the access parameters corresponding to the access mode, wherein the preset condition includes at least one of the following: transmission parameters when information is transmitted on the unlic...

Embodiment 2

[0182] In order to better understand the method in the above embodiment, this embodiment also provides an apparatus for accessing an unlicensed spectrum, which is applied to the above transmission node. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and what has been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0183] figure 2 It is a structural block diagram (1) of an access device for an unlicensed spectrum according to Embodiment 2 of the present invention, as shown in figure 2 As shown, the device includes:

[0184] The determining module 20 is configured to at least determine according to preset conditi...

Embodiment 3

[0240] In order to better understand the above-mentioned embodiments of the present invention, this embodiment further illustrates the present invention by means of preferred embodiments.

[0241] Figure 4 It is a flow chart of the method for accessing the unlicensed spectrum in Embodiment 3 of the present invention, such as Figure 4 Shown, main method step of the present invention comprises:

[0242] S401. The transmission node (terminal) of the first system determines an access mode and corresponding access parameters according to preset conditions;

[0243] S403. The transmission node accesses an unlicensed spectrum according to the determined access mode and corresponding access parameters, and the transmission node performs information transmission on the unlicensed spectrum.

[0244] Assuming frequency division duplex FDD downlink is located in the licensed spectrum, uplink is located in the unlicensed spectrum, the UE receives the downlink control information (Downl...

Abstract

The invention provides an access method and apparatus of an unauthorized spectrum, and a transmission node. The access method comprises the following steps: the transmission node determines an accessmode of the unauthorized spectrum and access parameters corresponding to the access mode according to preset conditions, wherein the preset conditions comprise at least one of the following: transmission parameters when information is transmitted on the unauthorized spectrum, the type of the information, a grade corresponding to the transmission node and access signaling; and the transmission nodeaccesses the unauthorized spectrum according to the determined access mode and the determined access parameters. By adoption of the access method and apparatus provided by the invention, the problemthat a narrow-band system cannot be supported to access the unauthorized spectrum in related art is solved, and an effective method of the narrow-band system to access the unauthorized spectrum is provided.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for accessing an unlicensed frequency spectrum, and a transmission node. Background technique [0002] Machine Type Communication (MTC for short) User Equipment (UE for short), also known as Machine to Machine (M2M for short) user communication equipment, is currently the main application form of the Internet of Things. In the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) technical report TR45.820V200, several technologies applicable to cellular-level Internet of Things (Comb-Internet Of Things, referred to as C-IOT) are disclosed. Networking (Narrow Band-Internet Of Things, referred to as NB-IoT) technology is the most eye-catching. [0003] It is well known that Long Term Evolution (LTE for short) is deployed and operated on licensed carriers. However, with the rapid growth of data services, in the near futu...
