Method and system for in-building radio unit applied to open LAN with frequency resource distribution
Disclosed herein is an in-building radio unit applied to an open LAN having an open base station structure. The in-building radio unit is configured to match a beam ID and a front-end unit based on beamforming information received from a base station; and communicatively connect a terminal and the base station via the matched front-end unit, the terminal and the base station being connected to the matched front-end unit.
1. An in-building radio unit applied to an open LAN having an open base station structure, the in-building radio unit being configured to:
match a beam ID and a front-end unit based on beamforming information received from a base station; and
communicatively connect a terminal and the base station via the matched front-end unit, the terminal and the base station being connected to the matched front-end unit,
wherein the in-building radio unit supports a fronthaul interface with the base station, the front-end unit being positioned between the in-building radio unit and the terminal to relay a communication signal;
wherein an extension unit configured to transmit a signal is further provided between the radio unit and the front-end unit; and
wherein the in-building radio unit matches the extension unit and the front-end unit based on an SSB index and a CSI-RS index acquired from SSB information extracted by pre-coding the beamforming information.
2. The in-building radio unit of claim 1 , wherein the terminal is wirelessly communicatively connected to the front-end unit rather than the radio unit.
3. The in-building radio unit of claim 2 , wherein the in-building radio unit is for in-building use and is communicatively connected to the base station by wire,
wherein the in-building radio unit distributes communication paths between the base station and the front-end unit based on the beamforming information.
4. The in-building radio unit of claim 1 , wherein the in-building radio unit skips transmission of an unmatched signal of the front-end unit except for a matched signal of the front-end unit according to the beamforming information.
5. The in-building radio unit of claim 1 , wherein the beamforming information is configured according to a generation period of C-plane data of the fronthaul interface.
6. The in-building radio unit of claim 5 , wherein the in-building radio unit pre-codes only the C-plane data of the fronthaul interface.
7. A system comprising:
the in-building radio unit according to claim 1 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
8. A method for controlling an in-building radio unit applied to an open LAN having an open base station structure, the method comprising:
matching, by the in-building radio unit, a beam ID and a front-end unit based on beamforming information received from a base station; and
communicatively connecting a terminal and the base station via the matched front-end unit, the terminal and the base station being connected to the matched front-end unit,
wherein the in-building radio unit supports a fronthaul interface with the base station, the front-end unit being positioned between the in-building radio unit and the terminal to relay a communication signal,
wherein an extension unit is positioned between the in-building radio unit and the front-end unit to transmit the signal,
wherein the matching comprises:
acquiring, by the in-building radio unit, an SSB index and a CSI-RS index from SSB information extracted by pre-coding the beamforming information;
matching, by the in-building radio unit, the extension unit based on the SSB index; and
matching, by the in-building radio unit, the front-end unit connected to the extension unit based on the CSI-RS index.
9. A system comprising:
the in-building radio unit according to claim 2 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
10. A system comprising:
the in-building radio unit according to claim 3 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
11. A system comprising:
the in-building radio unit according to claim 4 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
12. A system comprising:
the in-building radio unit according to claim 5 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
13. A system comprising:
the in-building radio unit according to claim 6 ; and
a base station and a terminal communicatively connected via the in-building radio unit.
