Abstract: Embodiments of the present invention disclose a method and an apparatus for transmitting data. The apparatus for transmitting data includes a high frequency radio unit HFRU that is in a communication connection with a site, and a shift frequency radio unit SFRU that is in a communication connection with the HFRU and with a user equipment, where the HFRU includes a high frequency radio unit—indoor device unit HFRU-IDU and a high frequency radio unit—outdoor device unit HFRU-ODU that connects to the HFRU-IDU, and the SFRU includes a high frequency band transceiver and a wireless cellular band transceiver. By converting to-be-transmitted data into intermediate frequency signals for transmission, the method and apparatus for transmitting data according to the embodiments of the present invention can remarkably reduce a data transmission bandwidth, thereby saving bandwidth resources, reducing a data transmission cost, and reducing a device deployment cost.

Abstract: The present invention provides a data transmission method, a remote radio unit RRU, and a baseband unit BBU. The method includes: receiving, by the RRU, stream data sent by the BBU, where the stream data is obtained after the BBU performs resource mapping processing on to-be-transmitted downlink data; performing, by the RRU, stream to antenna mapping processing on the stream data; and sending, by the RRU, mapping-processed data to user equipment by using an antenna. In the data transmission method of embodiments of the present invention, service stream data is transmitted between the BBU and the RRU. This can reduce data traffic between the BBU and the RRU, so as to reduce fronthaul data bandwidth between the BBU and the RRU.

Abstract: Embodiments of the present invention provide a cell management device and method. A data transmission delay between a coordinating cell and a serving cell is measured and compared with a requirement of a preset coordination manner for the data transmission delay, coordinating cells are managed by category according to the delay, a coordinating cell that satisfies the requirement of the preset coordination manner for the data transmission delay is identified, and then the coordinating cell that satisfies the delay requirement participates in coordinated communication of the cell with priority. Therefore, normal implementation of a coordinated function can be ensured, and an expected effect of the coordinated communication of the cell can be exerted. The device may be applicable to multiple networking cases and can be set flexibly, easily and conveniently.
