基地局装置及び通信制御方法
Document Type and Number:
Japanese Patent JP5268654
Kind Code:
B2
Abstract:
A base station for communicating with a mobile station which transmits an uplink signal according to a frequency division multiplexing scheme includes a first measurement unit configured to measure reception power on a frequency band for the random access channel in uplink or a second measurement unit configured to measure the number of receptions of preambles on the random access channel. The base station may either control the frequency band for the random access channel or restrict transmission on the random access channel based on at least one of the reception power on the frequency band for the random access channel and the number of receptions of preambles on the random access channel.
