Abstract

The present application discloses a generating and processing method of a pilot frequency sequence in a wireless communication system. The method comprises a step of generating a pilot frequency sequence for the pilot frequency position in the synchronization frame in an (nPRB)th frequency point according to a cell identification and the absolute frequency point index number of the (nPRB)th frequency point, and a step of mapping the generated pilot frequency sequence to the pilot frequency position corresponding to the synchronization frame in the (nPRB)th frequency point. By using the method, the pilot frequency structure of the resource allocation scheme of a downlink synchronization frame can be correctly matched.

Description

Technical field [0001] This application relates to the field of wireless communication technology, and in particular to a method for generating and processing a pilot sequence in a wireless communication system. Background technique [0002] In wireless communication systems, Orthogonal Frequency Division Multiplexing (OFDM) is a special frequency multiplexing technology that uses multi-carrier modulation. In the traditional frequency division multiplexing system (FDM): the entire signal frequency band is divided into N non-overlapping frequency sub-channels, each sub-channel transmits independent modulation symbols, and then the N sub-channels are frequency-multiplexed. This method It is beneficial to eliminate inter-channel interference, but cannot effectively use spectrum resources. OFDM technology can take advantage of the orthogonality between sub-carriers without the need for this guard band. This saves bandwidth, and OFDM has a higher spectrum utilization ratio than FDM....
