摘要
Various examples and schemes pertaining to reference signals with low power imbalance and low peak-to-average power ratio (PAPR) in mobile communications are described. A processor of an apparatus generates a multi-port multi-symbol reference signal (RS). The processor then controls a transmitter to transmit the multi-port multi-symbol RS through a plurality of antenna ports. In generating the multi-port multi-symbol RS, the processor performs either or both of: (1) modifying a time-domain orthogonal cover code (TD-OCC) pattern for code-division multiplexing (CDM) with respect to the multi-port multi-symbol RS such that time-domain power imbalance is reduced; and (2) performing a permutation on a respective sequence of each CDM group of a plurality of CDM groups with respect to the multi-port multi-symbol RS such that a peak-to-average power ratio (PAPR) is reduced.
