Methods and apparatus to support more dmrs ports for cp-ofdm waveform

Abstract

Apparatus and methods are provided for communication in a wireless network. A communication device processes a radio resource control (RRC) message from the wireless network including demodulation reference signal (DMRS) configuration information with at least one of a DMRS configuration type, a maximum number of DMRS symbols per location, a DMRS starting position, and a DMRS additional position. The communication device processes a dynamic DMRS mode indication from the wireless network for the communication device to select one of a first DMRS mode that supports up to 12 DMRS ports and a second DMRS mode that supports up to 24 DMRS ports. The communication device processes a DMRS based on a selection of the first DMRS mode or the second DMRS mode indicated by the dynamic DMRS mode indication from the wireless network.
