System and method for one cell to cover multiple areas

摘要

A system, method and network device for covering a plurality of areas by one cell are disclosed. The system includes: a plurality of radio frequency groups and at least one base band unit. One radio frequency group corresponds to one area of the cell, one radio frequency group corresponds to one date channel, and one base band unit is connected to a plurality of radio frequency groups through a plurality of date channels. The embodiment of the invention reduces the signal interference among each area of the same cell, increases the system capacity, and benefits cell splitting, i.e., benefits increasing the capacity and upgrading during network enhancement.

1. A system for one cell to cover multiple areas, comprising:
a baseband unit (BBU), wherein the BBU is connected with multiple radio frequency (RF) groups through multiple data channels, the multiple RF groups belong to the same cell, wherein areas which the multiple RF groups corresponds to in the cell are different from each other; wherein each of the multiple RF groups is configured to: receive uplink signals sent from a user equipment (UE) in a corresponding area, and send the uplink signals to the BBU through one of the multiple data channels corresponding to one of the multiple RF groups; and wherein the BBU is configured to search for the uplink signals on the one of the multiple data channels, to process the uplink signals when finding the uplink signals on the one of the multiple data channels, and to determine information about the one of the multiple data channels which the uplink signals of the UE are received from.
