METHOD AND DEVICE FOR PROCESSING RANDOM ACCESS PREAMBLE
First Claim
1. A method for processing a random access preamble, comprising:
- determining, according to a coverage radius of a cell, a guard time (GT) that is needed when a user equipment (UE) communicates with a base station, wherein the coverage radius of the cell is greater than 100 kilometres; and
determining, according to the GT, a random access preamble transmitted by the UE to the base station, wherein the random access preamble is transmitted on a special subframe and at least one regular subframe of a radio frame when the UE communicates with the base station.

Abstract
Provided are a method and device for processing a random access preamble. The method includes: determining, according to a coverage radius of a cell, a guard time (GT) that is needed when a user equipment (UE) communicates with a base station, wherein the coverage radius of the cell is greater than 100 kilometres; and, determining, according to the GT, a random access preamble transmitted by the UE to the base station, wherein the random access preamble is transmitted on a special subframe and at least one regular subframe of a radio frame when the UE communicates with the base station. The solution 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.
