CYCLIC PREFIX ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SEQUENCE CONFIGURATION OF A DOWNLINK / UPLINK

Abstract:

In an aspect, a network entity may receive download control information (DCI) indicating a first scrambling identification value, a second scrambling identification value, and a scrambling selection value, wherein the scrambling selection value has either a first scrambling selection value or a second scrambling selection value. The network entity may configure a first demodulation reference signal (DMRS) symbol sequence based on a first initial seed value, a second DMRS symbol sequence based on a second initial seed value, and a third DMRS symbol sequence based on a third initial seed value. The network entity may be configured, based on the scrambling selection value, to transmit or receive DMRS on a group of code division multiplexed (CDM) antenna ports based on either the first DMRS symbol sequence, the second DMRS symbol sequence, or the third DMRS symbol sequence.
