Abstract:
Embodiments of the present invention provide a multi-sector MIMO active antenna system and a communications device, where the multi-sector MIMO active antenna system includes N columns of dual-polarized antennas, where each column of dual-polarized antennas includes one column of antenna units in a first polarization direction and one column of antenna units in a second polarization direction, antenna array elements in an antenna unit in the first polarization direction are set to have a first antenna downtilt and serve a first sector, and antenna array elements in an antenna unit in the second polarization direction are set to have a second antenna downtilt and serve a second sector.
Abstract:
Embodiments of the present invention provide a method for optimizing a neighboring cell, a base station, and a system. The method includes: detecting, by the base station corresponding to the second cell, that a terminal in the second cell reports an unidentified physical identifier PCI; and obtaining a global cell identity GCI corresponding to the unidentified PCI, and determining that a cell corresponding to the GCI is an un-configured neighboring cell of the first cell; and sending, by the base station corresponding to the second cell, information about the un-configured neighboring cell to a base station BSS or an operations support system OSS, which is corresponding to the first cell, so that the BSS or OSS obtains the un-configured neighboring cell of the first cell according to the information of the un-configured neighboring cell, and adds the un-configured neighboring cell to a neighboring cell list of the first cell.
