Abstract: The disclosure provides a method and device for processing a random access preamble. The method includes: determining a Guard Time (GT) required by communication between a User Equipment (UE) and a base station according to a cell coverage radius, wherein the cell coverage radius is larger than 100 kilometers; and determining the random access preamble transmitted by the UE to the base station according to the GT, wherein the random access preamble is transmitted on an ordinary sub-frame in a radio frame during the communication between the UE and the base station. By the method and the device, the problem that the cell coverage radius of a single station cannot exceed 100 kilometers in a related technology is solved, and effects of enlarging the cell coverage radius of the single station and meeting a requirement on an ultra-large cell coverage radius in a special scenario are further achieved.

Abstract: A user service mode selection method in the case of 3D beams, a pilot frequency information sending method and apparatus are disclosed. The selection method includes: comparing the total number of the users to be served with that of scheduling units; selecting a single-user service mode for each user when the total number of the users to be served is smaller than that of scheduling units; selecting J user groups meeting a preset condition to adopt a multi-user service mode when the total number of the users to be served is not smaller than that of scheduling unit, J is an integer greater than 1, and 2J is an integer not greater than the total number of the users to be served; one time-frequency resource only corresponds to one beam configured for communication in the single-user service mode but at least two beams in the multi-user service mode.
