Abstract

The invention discloses a random access preamble processing method and device. The method includes: determining a time interval GT required by a user terminal UE to communicate with a base station according to a cell coverage radius, and the cell coverage radius is greater than 100 kilometers; The GT determines the random access preamble sent by the UE to the base station, wherein the random access preamble is sent on the special subframe and ordinary subframe in the radio frame when the UE communicates with the base station. The invention solves the problem of single-site coverage in a cell. The maximum range of the cell cannot meet the needs of special scenarios, which further improves the coverage radius of a single cell in a cell and meets the needs for cell coverage with a large radius in special scenarios.

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 ...
