Problems solved by technology

Also, due to the higher path loss of MMW links, it is possible that the density of MMW base stations is much higher than that of Long Term Evolution (LTE) base stations in low frequency bands, so mobile stations will need more frequent switching processes in the network
Additionally, MMW links will be more susceptible to obstruction by vehicles and user movement

Abstract

Embodiments of the present disclosure relate to a communication method, user equipment and a base station. An embodiment of the present disclosure provides a communication method implemented at a user equipment, including: establishing a first connection between the user equipment and a first base station, at least for the control plane transmission of the user equipment; establishing the user equipment and each of the base station clusters connection of the base station; and in response to the second base station in the base station cluster being selected as the serving base station of the user equipment, performing data plane transmission of the user equipment via the second connection between the user equipment and the second base station. According to the solutions of the embodiments of the present disclosure, a flexible network system and a fast and reliable mobility mechanism can be provided by considering the characteristics of the MMW physical channel being easily blocked and the MMW network using multi-antenna high-gain beamforming.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of wireless communication, and more specifically relate to a communication method implemented at a user equipment and a base station, a user equipment and a base station. Background technique [0002] Currently, the fifth generation mobile communication (5G) technology has become a research hotspot in the industry. In terms of wireless spectrum, the use of high frequency bands such as millimeter wave (MMW) bands for wireless communications is being actively promoted. [0003] In particular, 5G wireless / mobile access is expected to use MMW frequencies to provide high data transfer rates. The high frequency of MMW signals results in high path loss, while the small wavelength of these signals also enables a large number of antenna elements to be placed in the same physical area, thereby providing high beamforming gain. Also, due to the higher path loss of MMW links, it is possible that the densit...
