Embodiment Construction

[0064] As mentioned above, NR-based unlicensed spectrum communication technology has become a new technology hotspot. Based on the new characteristics of NR, LBT technology needs to be changed accordingly. However, there is currently no beam direction based LBT technique in NR scenarios.

[0065] In the NR scenario, data transmission can be performed based on multiple beams, and the beams can be distinguished by the type and serial number of the RS carrying the beams. Different beams have different beam directions. The beam direction in the embodiment of the present invention may be carried by a channel state information reference signal (CSI Reference Signal, CSI-RS), a channel sounding signal (Sounding Reference Signal, SRS), a tracking reference signal (Tracking Reference Signal, TRS), a synchronization signal It is distinguished from the spatial configuration (spatial configuration) of any one or more of resources in a broadcast channel block (SS / PBCH Block, SSB) and a d...

Abstract

The embodiment of the invention discloses an uplink LBT method and device, a medium and a terminal, and the method comprises the steps: determining the directions of to-be-monitored beams of one or more to-be-monitored beams, and enabling the to-be-monitored beams to be selected from beams in an unlicensed spectrum range; and monitoring the one or more beams to be monitored to determine a beam suitable for data transmission. According to the technical scheme provided by the invention, uplink LBT can be carried out in an NR scene.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to an uplink LBT method, device, medium, and terminal. Background technique [0002] Currently, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) will introduce a new wireless technology (New Radio access technology, NR), including at least the fifth generation mobile communication technology (5G). [0003] In wireless technologies, in order to improve the quality of communication services, unlicensed spectrum may be used for communication, that is, Licensed Assisted Access (LAA) technology. The Listen Before Talk (LBT) technology is an important part of the unlicensed spectrum communication technology. So far, the LAA based on the LTE protocol has many new features than the original LAA. [0004] With the evolution of communication technology, NR-based unlicensed spectrum communication technology has become a new technol...
