Abstract
Technology for a user equipment (UE) operable to decode a resource mapping pattern of a phase tracking reference signal (PT-RS) received from a base station in a wireless network is disclosed. The UE can decode control signaling received in a downlink from the base station. The control signaling can indicate a resource mapping pattern for a PT-RS. The UE can identify the resource mapping pattern for the PT-RS based on the control signaling received from the base station. The UE can encode one or more PT-RS for transmission to the base station in an uplink in accordance with the resource mapping pattern for the PT-RS.
Claims20
An apparatus of a user equipment (UE) operable to decode a phase tracking reference signal (PT-RS) configuration received from a base station for a PT-RS, the apparatus comprising:
- one or more processors configured to:
- decode, at the UE, the PT-RS configuration received from the base station for the PT-RS, wherein the PT-RS configuration includes a time density for the PT-RS and a frequency density for the PT-RS;
- and
- encode, at the UE, the PT-RS for transmission in an uplink to the base station in accordance with the PT-RS configuration received from the base station;
- and
- a memory interface configured to send to a memory the PT-RS configuration.
An apparatus of a base station operable to encode a resource mapping pattern of a phase tracking reference signal (PT-RS) for transmission to a user equipment (UE) in a wireless network, the apparatus comprising:
- one or more processors configured to:
- determine, at the base station, the resource mapping pattern for the PT-RS;
- encode, at the base station, control signaling for transmission to the UE, wherein the control signaling indicates the resource mapping pattern for the PT-RS;
- and
- decode, at the base station, one or more PT-RS received from the UE in an uplink in accordance with the resource mapping pattern for the PT-RS indicated by the base station;
- and
- a memory interface configured to send to a memory the resource mapping pattern for the PT-RS.
At least one non-transitory machine readable storage medium having instructions embodied thereon for decoding a phase tracking reference signal (PT-RS) configuration received at a user equipment (UE) from a base station for a PT-RS, the instructions when executed by one or more processors of the UE perform the following:
- decoding, at the UE, the PT-RS configuration received from the base station for the PT-RS, wherein the PT-RS configuration includes a time density for the PT-RS and a frequency density for the PT-RS;
- and
- encoding, at the UE, the PT-RS for transmission in an uplink to the base station in accordance with the PT-RS configuration received from the base station.
