The present invention discloses a method and an apparatus for mapping pathloss of a neighboring cell in a Time Division Duplex-Long Term Evolution (TDD-LTE) system. The method includes: a Base Station (BS) configuring a Reference Signal Received Power (RSRP) trigger parameter and a Power Headroom Report (PHR) trigger parameter for terminals; classifying the terminals based on the time when the terminals report the RSRPs and/or PHRs; and mapping the neighboring cell pathloss of the terminal based on the classification result, stored RSRP of the local cell, stored RSRP and PHR of the neighboring cell and the measured receiving power values of the terminals. With the present invention, the terminals are classified based on various pathloss-related power information reported by the terminals and the update time, and the neighboring cell pathloss of the terminal is estimated based on the classification result. Therefore, the BS obtains the pathloss information of a neighboring cell, and the TDD-LTE uplink power control with limited interference is realized. |
