Abstract

One or more shared data channels, e.g., PDSCH, PUSCH, PSSCH, are configured to be DMRS-free, thus allowing the resources which would be used for DMRS to be used to convey additional traffic data signals. Channel estimation based on control channel DMRS, e.g., PDCCH DMRS, PUCCH DMRS, or PSSCH/PSCCH DMRS, is used to demodulate and/or decode the traffic channel signals communicated on the DMRS-free shared traffic channel resources. Antenna port hopping is implemented as part of the PDCCH configuration to support a DMRS-free PDSCH. The antenna port hopping of the PDCCH is used to obtain a set of channel estimates based on PDDCH DMRS corresponding to different antenna ports which will match the antenna ports used for the PDSCH.
