METHOD AND SYSTEM FOR REFERENCE SIGNAL PATTERN DESIGN IN RESOURCE BLOCKS

摘要

A base station is provided. The base station comprises a downlink transmit path comprising circuitry configured to transmit a plurality of reference signals in two or more resource blocks. Each resource block comprises S OFDM symbols. Each of the S OFDM symbols comprises N subcarriers, and each subcarrier of each OFDM symbol comprises a resource element. The base station further comprises a reference signal allocator configured to allocate the plurality of reference signals to selected resource elements of the two or more resource blocks according to a reference signal pattern. A same pre-coding matrix is applied across the two or more resource blocks.
