Abstract

Embodiments of the invention relate to a method and a device for determining a remote radio unit (RRU). The method comprises: a base band unit (BBU) obtains an interference intensity information of a user equipment, and the interference intensity information comprises a downlink mode of the user equipment; if the downlink mode uses a dedicated reference signal (DRS) for demodulation, the BBU uses a second RRU for resource scheduling of the user equipment, and the second RRU is picked by the BBU from a plurality of first RRUs of a user equipment service; or if the downlink mode does not use the DRS for demodulation, the BBU uses a third RRU for resource scheduling of the user equipment, wherein the third RRU is determined by the BBU according to any one of an uplink signal strength value, a downlink quality value and an uplink quality value of the user equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for determining the RRU of a radio frequency unit. Background technique [0002] Currently, long-term evolution (LTE for short) systems generally use the same-frequency networking mode, causing serious interference between cells; especially in a network with a high site density, the interference is particularly obvious. [0003] The technology of using multiple remote radio units (Remote Radio Units, RRUs for short) sharing a cell can reduce interference when densely deployed stations and obtain a combined gain. The technology of multiple RRUs sharing a cell is specifically a technology of combining multiple RRUs into one cell and performing joint transmission to all terminals. [0004] In the prior art, a base station uses a multi-RRU co-cell technology to perform resource scheduling for a terminal. Specific process such as figure 1 shown. The base st...
