摘要： A method for operating a terminal for supporting a handover in a heterogeneous network is provided. The method includes measuring received signal strength from a target small base station, so that a Signal-to-Noise Ratio (SNR) is estimated, when the SNR of the target small base station that considers a biased value for range expansion is greater than an SNR of a serving macro base station, determining whether an SNR of the target small base station that does not consider the biased value for the range expansion is equal to or less than a threshold, and when the SNR of the target small base station that does not consider the biased value for the range expansion is equal to or less than the threshold, transmitting indication information, informing that a low SNR is expected when the terminal performs a handover to the target small base station, to the serving macro base station.

摘要： Provided are an apparatus and method for transmitting/receiving a pilot code pattern used to identify a base station. In the base station, a pilot code pattern determiner determines a code set that includes a number of spreading codes based on a specific ID of the base station. A first spreader spreads a pilot symbol mapped onto an FC with a corresponding spreading code according to the determined code set, and controls gain so as to transmit the pilot symbol at a higher signal level than data. A second spreader spreads data symbols mapped onto the FC with spreading codes of the code set except for the spreading code used for the pilot spreading. A mapper groups a spread signal from the first spreader and spread signals from the second spreader on a TFC basis, and outputs signals that constitute each TFC to points of sub-carriers. An IFFT unit performs an IFFT operation on signals output from the mapper. Because the pilot as well as the data is spread, it is easy to implement the base station. Also, it is possible to identify base stations according to the pilot spreading codes as well as a pilot hopping pattern.
