REFERENCE SIGNAL DESIGN FOR SPECIAL SUBFRAME CONFIGURATIONS

摘要

are illustrative embodiment of a base station for transmitting reference signals in the TDD wireless communication network and relates to the corresponding method , if the transmission format is a demodulation reference signal (DMRS) based format , the base station is 6 : 6: 2 the specific sub-frame configuration to build a particular time and frequency orthogonal frequency division multiplexed with the timing ratio (OFDM) and the reference signal sent to the user equipment in accordance with the grid , DMRS pattern is spanning over a four OFDM symbol time and frequency . ;
