Abstract
Technology for a next generation node B (gNB), operable to use phase tracking reference signals (PT-RS) is disclosed. The gNB can identify a modulation and coding 5 scheme (MCS) for the UE for a bandwidth part (BWP) with a subcarrier spacing (SCS). The gNB can select a time density of the PT-RS based on the MCS. The gNB can select a frequency density of the PT-RS based on an allocated bandwidth in the BWP. The gNB can encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling.

An apparatus of a next generation node B (gNB), operable to use phase tracking reference signals (PT-RS), the apparatus comprising:
- one or more processors configured to:
- identify a modulation and coding scheme (MCS) for the UE for a bandwidth part (BWP) with a subcarrier spacing (SCS);
- select a time density of the PT-RS based on the MCS;
- select a frequency density of the PT-RS based on an allocated bandwidth in the BWP;
- and
- encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling;
- and
- a memory interface configured to send to a memory the time density based on the MCS, and frequency density based on the allocated bandwidth.
An apparatus of a user equipment (UE), operable to use phase tracking reference signals (PT-RS), the apparatus comprising:
- one or more processors configured to:
- decode a modulation and coding scheme (MCS) received from a next generation node B (gNB) for a bandwidth part (BWP) with a subcarrier spacing (SCS);
- decode, a higher layer signal that includes a time density of the PT-RS based on the MCS for the BWP;
- decode, the higher layer signal that includes a frequency density of the PT-RS based on an allocated bandwidth in the BWP;
- and
- demodulate symbols received in a physical downlink shared channel (PDSCH) that are associated with the PT-RS, using the PT-RS;
- and
- a memory interface configured to send to a memory the time density based on the MCS and the frequency density based on allocated bandwidth.
At least one machine readable storage medium having instructions embodied thereon for a next generation node B (gNB), operable to use phase tracking reference signals (PT-RS), the instructions thereon when executed by one or more processors at the UE perform the following:
- select a time density of the PT-RS based on a modulation and coding scheme (MCS);
- select a frequency density of the PT-RS based on an allocated bandwidth of the BWP;
- and
- encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling.
