Channel-state-information reference signals for advanced wireless systems
A mobile station includes a receiver configured to receive containing a complex-valued modulation symbol from a base station, a processor configured to extract the complex-valued modulation symbol from the signal, wherein in response to being configured with code-division multiplex-4 (CDM-4), the complex-valued modulation symbol is mapped using a reference signal sequence. A base station includes a processor configured to generate a reference signal sequence for each subcarrier and OFDM symbol, and in response to being configured with code-division multiplex-4 (CDM-4), map a reference signal sequence to the complex-valued modulation symbols. Other embodiments including a method for performing communication on multiple input multiple output (MIMO) radio links are also disclosed.
