Description

Method and device for establishing neighbor relationship of wireless access network node

This close-range wireless communication can ensure the high reliability of the communication link on the one hand, and can also improve the spectrum multiplexing in the area on the other hand. Efficiency, which can further increase network capacity. At the same time, the short-range communication between the user and the wireless access network node enables the millimeter wave to be used in an ultra-dense network, and the millimeter-wave rich frequency resource provides a larger bandwidth for the ultra-dense network, thereby further improving Network capacity.
