Physical uplink control channel design for discrete fourier transform-spread-orthogonal frequency-division multiplexing (DFT-s-OFDM) waveforms
Various embodiments herein provide physical uplink control channel (PUCCH) designs for discrete Fourier transform-spread-orthogonal frequency-division multiplexing (DFT-s-OFDM) waveforms for systems operating above the 52.6 GHz carrier frequency. Some embodiments of the present disclosure may be directed to phase tracking reference signal (PT-RS) design for PUCCH with carrier frequencies above 52.6 GHz. Other embodiments may be disclosed and/or claimed.
1. An apparatus comprising:
memory to store demodulation reference signal (DMRS) information and uplink control information (UCI); and
processor circuitry, coupled with the memory, to:
retrieve the DMRS information and UCI from the memory;
multiplex the DMRS information and UCI in a time division multiplexing (TDM) manner; and
encode a message that includes the multiplexed DMRS information and UCI for transmission.
2. The apparatus of claim 1 , wherein the message is a physical uplink control channel (PUCCH) message.
3. The apparatus of claim 1 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation.
4. The apparatus of claim 1 , wherein the DMRS information and UCI occupy a common frequency domain resource.
5. The apparatus of claim 1 , wherein the message includes phase tracking reference signal (PT-RS) information.
6. The apparatus of claim 1 , wherein the UCI spans one or two symbols.
7. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, are to cause a user equipment (UE) to:
multiplex demodulation reference signal (DMRS) information and uplink control information (UCI) together in a time division multiplexing (TDM) manner; and
encode a message that includes the multiplexed DMRS information and UCI for transmission.
8. The one or more non-transitory computer-readable media of claim 7 , wherein the message is a physical uplink control channel (PUCCH) message.
9. The one or more non-transitory computer-readable media of claim 7 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation.
10. The one or more non-transitory computer-readable media of claim 7 , wherein the DMRS information and UCI occupy a common frequency domain resource.
11. The one or more non-transitory computer-readable media of claim 7 , wherein the message includes phase tracking reference signal (PT-RS) information.
12. The one or more non-transitory computer-readable media of claim 7 , wherein the UCI spans one or two symbols.
13. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, are to cause a user equipment (UE) to:
multiplex demodulation reference signal (DMRS) information and uplink control information (UCI) in a time division multiplexing (TDM) manner for a physical uplink control channel (PUCCH) message; and
encode the PUCCH message for transmission to a next-generation NodeB (gNB).
14. The one or more non-transitory computer-readable media of claim 13 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation.
15. The one or more non-transitory computer-readable media of claim 13 , wherein the DMRS information and UCI occupy a common frequency domain resource.
16. The one or more non-transitory computer-readable media of claim 13 , wherein the message includes phase tracking reference signal (PT-RS) information.
17. The one or more non-transitory computer-readable media of claim 13 , wherein the UCI spans one or two symbols.
