Abstract

Disclosed are a method and device for processing a random access preamble. The method comprises: determining, on the basis of the coverage radius of a cell, a time interval time slot (GT) that is needed when a user equipment (UE) communicates with a base station, where the coverage radius of the cell is greater than 100 kilometers; and, determining, on the basis of the GT, the random access preamble transmitted by the UE to the base station, where the random access preamble is transmitted by means of a special subframe and a regular subframe in a radio frame when the UE and the base station are communicating. The present invention solves the problem that the maximum coverage range of a single-station cell cannot satisfy a need in a special scenario, further increases the coverage radius of the single-station cell, and satisfies the need in the special scenario for an extra-large radius in cell coverage range.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a random access preamble processing method and device. Background technique [0002] Time Division-Long Term Evolution (TD-LTE for short) is one of the fourth generation (4th Generation, 4G for short) mobile communication technologies and standards, and its technical advantages are reflected in speed, delay and spectrum utilization In many fields such as high frequency, it has the ability to provide more powerful services on limited spectrum bandwidth resources. [0003] TD-LTE services and applications have also expanded to more and more fields. For example, in special scenarios such as air routes or sea surfaces, it is usually required that the coverage radius of a single-site cell is large enough to reduce the demand for deploying site resources and alleviate the pressure of hard-to-find sites. Therefore, in the scenario of air route coverage, a single station is required ...
