[0038] Such as figure 1 As shown, the embodiment of the present invention provides an information transmission method in an unlicensed frequency band, which is applied to network equipment, and specifically includes the following steps:

[0039] Step 11: Listen to the transmission channel of at least one BWP in the first bandwidth part BWP in the unlicensed frequency band respectively, and obtain the channel listening result.

[0040] Wherein, the first BWP is at least one BWP configured by the network device for the terminal, the first BWP refers to the BWP configured by the network device for the terminal, refers to the type of BWP rather than the number, and the network device can configure one or at least two BWPs for the terminal. BWP, these BWP can be called the first BWP.

[0041]Among them, in order to avoid the problem of being unable to transmit due to only listening to a specific BWP (such as activating the active BWP), the network device can configure at least two...

Abstract

The invention discloses an information transmission method, network equipment and terminal in an unlicensed frequency band. The method includes: respectively intercepting the transmission channel of at least one BWP in the first bandwidth part BWP in the unlicensed frequency band to obtain the channel Listening result; wherein, the first BWP is at least one BWP configured by the network device for the terminal; if the channel listening result indicates that there is a BWP with an idle transmission channel in the first BWP, select at least one BWP among the BWPs with an idle transmission channel to determine It is the first activated BWP; on the first activated BWP, information is sent to the terminal. The invention detects multiple configured BWPs on the unlicensed frequency band, and transmits on the BWP whose channel is idle. In this way, by listening to multiple BWPs, other BWPs can be used for transmission when one BWP is busy, thereby improving resource utilization.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, network equipment and terminal in an unlicensed frequency band. Background technique [0002] In the future fifth generation (5 th Generation, 5G) communication system, or New Radio (NR) system, the unlicensed frequency band (unlicensed band) can be used as a supplement to the licensed frequency band (licensed band) to help operators expand the service. In order to be consistent with NR deployment and maximize NR-based unlicensed access as much as possible, the unlicensed frequency band can work in the 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80MHz or 100MHz) of the unlicensed frequency band can reduce the implementation complexity of network devices and terminals. Since the unlicensed frequency band is shared by multiple radio access technologies (Radio Access Technology, RATs), such as WiFi, radar, Long Te...
