Abstract
This disclosure provides an apparatus and a method for wireless communication. Processing circuitry of the apparatus determines one or more antenna ports of the apparatus for data transmission. The processing circuitry generates, for each of the one or more antenna ports, a respective demodulation reference signal (DMRS) based on one of a first DMRS pattern, a second DMRS pattern, a third DMRS pattern, and a fourth DMRS pattern. The one or more antenna ports transmit the one or more DMRSs. The first DMRS pattern includes four code division multiplexing (CDM) groups each comprising a length-2 orthogonal cover code (OCC), the second DMRS pattern includes six CDM groups each comprising a length-2 OCC, the third DMRS pattern includes three CDM groups each comprising a length-4 OCC, and the fourth DMRS pattern includes two CDM groups each comprising a length-6 OCC.
