Interval extension method in wireless communication systems.

摘要

Interval extension method in wireless communication systems. The present invention provides a method for range extension in wireless communication systems. One embodiment of the method includes determining whether a mobile unit is within a first range corresponding to a timing advance range supported by a timing advance command. This embodiment also includes transmitting a plurality of timing advance commands to the mobile unit when the mobile unit is outside the first range so that the mobile unit may be synchronized with the base station by combining information in the plurality of commands. of timing advance.
