SYSTEM AND METHOD FOR MAPPING REFERENCE SIGNAL SEQUENCE IN ADVANCED LONG TERM EVOLUTION SYSTEM

摘要

A method and system for mapping a reference signal sequence in the advanced long term evolution (LTE) system are provided and used for mapping the reference signal sequence to the orthogonal frequency division multiplexing symbol l. The method includes: when the system employs a normal cyclic prefix, determining the symbol l according to a expression, and mapping the reference signal sequence to the location of the sub-carrier k on the symbol l of a antenna port p; and the system includes: a mapping module, a first acquiring module and a second acquiring module. The provided system and method ensure the transmitting performance while ensure the interference randomization are compatible with the existing LTE system, realize the high-order Multiple In And Multiple Out (MIMO) transmission, support the usage of the corresponding technique, and increase the entire performance of the system.
