Network management device, base station device and network management method

摘要

Provided is a network management device capable of suppressing interference of a preamble between cells while securing a predetermined resource. An FGW (500) as the device is a network management device for managing a plurality of base station devices each of which perform communication with communication terminal devices by the SC-FDMA method, wherein the FGW (500) is provided with a parameter determination unit (530) for determining parameters related to an uplink preamble with respect to at least one among the plurality of base station devices, and a parameter notification unit (540) for sending notifications of the determined parameters to the base station devices for which the parameters have been determined; wherein the parameter determination unit (530) determines the parameters so that transmitted sequences of the preamble do not overlap between at least two of the plurality of base station devices.

主权项

1. A base station apparatus having a cell coverage at least partially overlapping with a cell coverage of another base station apparatus comprising:
a receiver structured to receive radio signals; and a preamble detector structured to detect an uplink preamble by peak search with respect to the received radio signals, wherein the preamble detector includes a processor that limits performance of the peak search within a time range that is shorter than a time range of peak search performed by the another base station apparatus having the at least partially overlapping cell coverage.
