Abstract: Systems and methods for mixed space time and space frequency block coding are provided. In some embodiments, a method of operating a first node in a wireless communication network for providing time and frequency diversity includes precoding modulation symbols intended for a second node according to two antenna ports on which they are to be transmitted. In a first subset of Orthogonal Frequency-Division Multiplexing (OFDM) symbols, mapping the precoded modulation symbols to resource elements starting first with indices corresponds to frequency. In a different subset of OFDM symbols, mapping the precoded modulation symbols to resource elements in any two adjacent OFDM symbols starting first with indices corresponds to time. In this way, transmission efficiency may be increased by not having any resource elements unused. Additional flexibility for precoding may also be provided when there is no symbol pair mapped to resource elements across two resource blocks.
