In conventional 3GPP (3 rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution) systems, data transmission can only occur on licensed spectrum, however, with a drastic increase in traffic, especially in some urban areas, the licensed spectrum may be difficult to meet the traffic demand. Communications on unlicensed spectrum in Release 13 and Release 14 are introduced by the cellular system and used for transmission of downlink and uplink data. To ensure compatibility with access technologies on other unlicensed spectrum, LBT (Listen Before Talk ) technology is adopted by LAA (Licensed Assisted Access, licensed spectrum assisted access) to avoid interference due to multiple transmitters simultaneously occupying the same frequency resources.

Currently, a technical discussion of 5G NR (New Radio Access Technology ) is in progress, in which Massive (Massive) MIMO (Multi-Input Multi-Output) is one of research hotspots for next generation mobile communications. In massive MIMO, to ensure that a user equipment can flexibly switch under multiple beams, a related procedure of Beam Management (Beam Management) is defined and adopted in 5G NR; wherein the user equipment may dynamically recommend a Candidate Beam (Candidate Beam) to the base station via a BRR (Beam Recovery Request) to replace the current Serving Beam (Serving Beam), and the base station then acknowledges to the user equipment that the BRR has been known to the base station by transmitting a BRR Response (Response) on the recommended Candidate Beam in a predefined time window and transmits a signal using the new Candidate Beam in a subsequent schedule. When the above procedure is applied to unlicensed spectrum, new mechanisms need to be designed.
