Abstract
A device configured to process multiple tables, each containing one or more entries relating to the selection of a demodulated reference signal (DMRS) port for a physical uplink shared channel (PUSCH), based on signals received from a network; to process a DMRS configuration for a PUSCH based on signals received from a network; to select an entry from one of the multiple tables based on the DMRS configuration; and to generate a PUSCH with a DMRS on the DMRS port corresponding to the entry for transmission.
