METHOD OF CONTROLLING UPLINK NOISE LEVEL IN MULTI-RU ENVIRONMENT |
摘要 |
Provided is a method of controlling an uplink noise level in a multi-radio unit (RU) environment in which each RU measures an ordinary noise level using a power monitoring function thereof when there is no user traffic and then controls an uplink noise level based on the ordinary noise level. |

1. A method of controlling an uplink noise level performed by each of radio units (RUs) connected to one digital unit (DU) in a multi-RU environment, the method comprising:
(a) measuring powers of all signals input for at least 24 hours N times an hour at time intervals of T; (b) selecting M pieces of data in order of increasing value from among hourly power data measured in operation (a); (c) estimating a noise power of every hour within 24 hours using a method of estimating a noise power of the corresponding hour by averaging the M pieces of data selected in operation (b); (d) selecting a minimum from among the noise powers estimated in operation (c) and determining the selected minimum as a noise power; and (e) adjusting a gain of an amplifier based on the determined noise power. |
