Abstract
The present application relates to devices and components including apparatus, systems, and methods for physical uplink shared channel transmissions with repetitions on different transmit beams with phase tracking reference signals.
Claims18
One or more non-transitory computer-readable media having instructions that, when executed by one or more processors, cause an apparatus to:
- process scheduling information to determine a schedule of a physical uplink shared channel (PUSCH) transmission with a plurality of repetitions, wherein the plurality of repetitions include at least two repetition sets to be respectively transmitted with at least two transmit beams;
- determine a number of phase tracking reference signal (PTRS) ports to be used for transmitting PTRSs associated with each of the at least two repetition sets;
- cause the PUSCH transmission to be transmitted with the plurality of repetitions using the at least two transmit beams;
- and
- cause the PTRSs to be transmitted by the number of PTRS ports.
2 more elements
An apparatus comprising:
- memory to store a phase tracking reference signal (PTRS)-demodulation reference signal (DMRS) association table;
- and
- processing circuitry coupled with the memory, the processing circuitry to:
- process one or more downlink control information (DCI) to:
- schedule a physical uplink shared channel (PUSCH) transmission with a first repetition set that include one or more repetitions that share a first scheduling request indicator (SRI) or transmitted precoding matrix indicator (TPMI) and a second repetition set that include one or more repetitions that share a second SRI/TPMI;
- and to indicate, in a single field or a plurality of fields, one or more association values;
- determine, based on the one more association values and the PTRS-DMRS association table, a PTRS-to-DMRS association for the first repetition set or the second repetition set;
- cause a PTRS to be transmitted based on the PTRS-to-DMRS association;
- and
- cause the first repetition set and the second repetition set to be transmitted.
7 more elements
A method of comprising:
- transmitting, to a user equipment, radio resource control (RRC) signaling for a configured grant-physical uplink shared channel (CG-PUSCH) transmission with a plurality of repetition sets, wherein the RRC signaling includes one or more parameters to configure the plurality of repetition sets with a corresponding plurality of phase tracking reference signal PTRS-to-demodulation reference signal (DMRS associations;
- receiving the CG-PUSCH transmission;
- receiving PTRSs associated with the CG-PUSCH transmission;
- and
- processing the CG-PUSCH transmission based on receiving of the PTRSs associated with the CG-PUSCH transmission.
