Title:
IN-BUILDING RADIO UNIT APPLIED TO OPEN-RAN HAVING DISTRIBUTED FREQUENCY RESOURCE CHANNELS TO FRONT-END UNITS, SYSTEM COMPRISING SAME, AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2023/163259
Kind Code:
A1
Abstract:
The present invention provides an in-building radio unit applied to open-RAN. The in-building radio unit, which is applied to open-RAN having an open base station structure, matches beam IDs and front-end units on the basis of beam-forming data received from a base station, and, with the matched front-end units as intermediaries, establishes a connection to allow communication between the base station and terminal connected to the front-end units. Accordingly, in an in-building radio unit applied to open-RAN having an open base station structure, the occurrence of uplink noise that accumulates as the number of front-end units increases can be eliminated.
