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.
Claims16
A user equipment (UE) operable to receive one or more phase tracking reference signals (PT-RS) from a base station in a wireless network, the UE comprising:
- one or more processors configured to:
- decode, at the UE, control signaling received in a downlink from the base station, wherein the control signaling indicates a resource mapping pattern for the one or more PT-RS;
- select, at the UE, the resource mapping pattern for the one or more PT-RS from a set of resource mapping patterns that are predefined at the UE, wherein the resource mapping pattern for the one or more PT-RS is selected based on the control signaling received from the base station;
- and
- receive, at the UE, the one or more PT-RS in accordance with the resource mapping pattern for the one or more PT-RS;
- and
- a memory interface configured to send to a memory the resource mapping pattern for the one or more PT-RS.
A method of a user equipment (UE) operable to receive one or more phase tracking reference signals (PT-RS) from a base station in a wireless network, the method comprising:
- decoding, at the UE, control signaling received in a downlink from the base station, wherein the control signaling indicates a resource mapping pattern for the one or more PT-RS;
- selecting, at the UE, the resource mapping pattern for the one or more PT-RS from a set of resource mapping patterns that are predefined at the UE, wherein the resource mapping pattern for the one or more PT-RS is selected based on the control signaling received from the base station;
- and
- receiving, at the UE, the one or more PT-RS in accordance with the resource mapping pattern for the one or more PT-RS.
