Abstract
Embodiments of the present disclosure provide for indications of demodulation reference signal port groups and phase-tracking reference signal port indications. Other embodiments may be described and claimed.
Claims24
One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a user equipment (UE) to:
- determine a number of demodulation reference signal (DMRS) port groups for a physical downlink shared channel (PDSCH) transmission;
- receive one or more DMRSs via the number of DMRS port groups;
- and
- demodulate the PDSCH transmission based on reception of the one or more DMRSs.
1 more element
An apparatus to be implemented in a transmission reception point (TRP), the apparatus comprising:
- processing circuitry to:
- generate an indication of a number of demodulation reference signal (DMRS) port groups;
- generate a plurality of demodulation reference signals (DMRSs) to be transmitted;
- and
- generate demodulation reference signals to be transmitted on resource elements of a physical downlink shared channel (PDSCH);
- and
- interface circuitry, coupled with the processing circuitry, to cause transmission of the indication and the DMRS by antenna ports of a DMRS port group of the number of DMRS port groups.
4 more elements
One or more non-transitory, computer-readable media having instructions that, when executed, cause a device to:
- read a transmission configuration indication (TCI) configuration for a physical downlink shared channel (PDSCH) transmission;
- determine a number of demodulation reference signal (DMRS) port groups based on the TCI configuration;
- determine a table based on the number of DMRS port groups;
- and
- determine a DMRS antenna port index based on the table and an indication in downlink control information (DCI).
2 more elements
An apparatus comprising:
- means for determining an association between one or more phase tracking reference signal (PT-RS) antenna ports (APs) and at least one demodulation reference signal (DMRS) port groups;
- and
- means for receiving PT-RS and DMRS based on the association;
- and
- means for demodulating a physical downlink shared channel based on the received PT-RS and DMRS.
