METHOD AND SYSTEM FOR REALIZING COVERING SECTORS BY USING ENANTIOMORPHOUS RADIO UNITS

摘要

The present invention provides a method and a system for realizing covering sectors by using enantiomorphous radio units. The method includes: a plurality of radio units being connected to a baseband unit after the radio units are concatenated with each other, except for a remotest radio unit, the other radio units being all the enantiomorphous radio units; each enantiomorphous radio unit independently converting uplink analog signals received from the corresponding coverage sector to digital signals, the remotest radio unit transferring the obtained digital signals to the next stage enantiomorphous radio unit; each stage enantiomorphous radio unit adding the digital signals transferred from the upper stage enantiomorphous radio unit to the digital signals obtained by sampling locally, then transferring the added digital signals to the next stage, transferring stage by stage as such until the last enantiomorphous radio unit transfers the added digital signals to the baseband unit to perform baseband processes. By using the method of the present invention, a plurality of covered sectors in a same cell could be obtained to satisfy the coverage need for a network, reduce the need for process abilities of the baseband process unit, and reduce costs for establishing the network.
