Beam reference signal for broadcast decoding
Methods, systems, and devices for wireless communication are described. A base station may transmit a subframe that includes physical broadcast channel (PBCH) signals interspersed within beam reference signals, where the subframe may be a synchronization subframe including one or more synchronization signals. In some cases, the beam reference signals from different antenna ports may be code division multiplexed or frequency division multiplexed over multiple frequency tones. A user equipment (UE) may use the beam reference signals to generate channel estimates for the PBCH signals. In some cases, orthogonal cover codes for code division multiplexed signals may be selected to facilitate generation of channel estimates for PBCH signals transmitted using nearby frequency tones.
