METHOD AND SYSTEM FOR IMPLEMENTING PCFICH MAPPING

摘要

Disclosed are a method and a system for implementing PCFICH mapping. The method comprises: performing mapping to first one, two or three OFDM symbols of a first time slot of each sub-frame in a time domain on the basis of an REG, a mapping position in a frequency domain being determined by at least one of the total number of REGs, the number of symbols occupied by the PCFICH, the system bandwidth, the number of sub-carriers in a resource block, and a cell physical layer identifier; and according to the mapping positions in the time domain and frequency domain, applying the REGs to form the PCFICH. The present invention implements the technology of PCFICH mapping, and can solve the problem of transmission reliability of PCFICH of an out-of-band relay in a high-speed mobile scenario, thereby increasing the accuracy of the out-of-band relay (or a terminal of a higher version) receiving the PCFICH, reducing the bit error rate of data transmission, increasing the anti-interference capability of the PCFICH, and improving the transmission efficiency of the whole communication system.
