Abstract
A method, wireless device, and network node for increasing the capacity on a control channel when using Frequency Division Multiplexing (FDM) of data and DMRS are disclosed. According to one aspect, a wireless device (WD) is configured to perform intra-symbol frequency division multiplexing of data subcarriers and demodulation reference signal, DMRS, subcarriers. The WD is also configured to apply intra-symbol orthogonal cover codes, OCCs, to the data subcarriers. The WD is further configured to apply intra-symbol cyclic shifts to the DMRS subcarriers.
