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.

Abstract: A signal transmission method is performed by a base station. The method includes: determining, a first carrier signal that is to be sent in a first cell on a first carrier and a second carrier signal that is to be sent in a second cell on a second carrier; mapping, the first carrier signal and the second carrier signal to N physical ports of an RRU, so that within a same OFDM symbol, a type B symbol used to transmit a pilot in the first carrier signal and a type B symbol used to transmit a pilot in the second carrier signal are mapped to different physical ports, and a total power of signals sent on each of N physical channels is not greater than a rated power of the RRU; and sending, the first carrier signal and the second carrier signal through the N physical ports.
