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. One or more non-transitory computer-readable media (NTCRM) comprising instructions that, upon execution of the instructions by one or more processors of a base station, are to cause the base station to:
identify a message received from a user equipment (UE), wherein the message includes demodulation reference signal (DMRS) information that is time division multiplexed with uplink control information (UCI); and
demultiplex the message to identify the DMRS information and the UCI:
wherein the message is transmitted on a carrier frequency that is at or above 52.6 gigahertz (GHz).
2. The one or more NTCRM of claim 1 , wherein the message is a physical uplink control channel (PUCCH) message.
3. The one or more NTCRM of claim 1 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation by the UE to generate the message.
4. The one or more NTCRM of claim 1 , wherein the DMRS information and UCI occupy a common frequency domain resource.
5. The one or more NTCRM of claim 1 , wherein the message further includes phase tracking reference signal (PT-RS) information.
6. The one or more NTCRM of claim 1 , wherein the UCI spans one or two symbols.
7. A base station comprising: 2—one or more processors;
and one or more non-transitory computer-readable media comprising instructions that, upon execution of the instructions by the one or more processors, are to cause the one or more processors to:
identify a message received from a user equipment (UE), wherein the message includes demodulation reference signal (DMRS) information that is time division multiplexed with uplink control information (UCI); and
demultiplex the message to identify the DMRS information and the UCH
wherein the message is transmitted on a carrier frequency that is at or above 52.6 gigahertz (GHz).
8. The base station of claim 7 , wherein the message is a physical uplink control channel (PUCCH) message.
9. The base station of claim 7 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation by the UE to generate the message.
10. The base station of claim 7 , wherein the DMRS information and UCI occupy a common frequency domain resource.
11. The base station of claim 7 , wherein the message further includes phase tracking reference signal (PT-RS) information.
12. The base station of claim 7 , wherein the UCI spans one or two symbols.
13. A user equipment (UE) comprising:
one or more processors; and
one or more non-transitory computer-readable media comprising instructions that, upon execution of the instructions by the one or more processors, are to cause the UE to:
multiplex demodulation reference signal (DMRS) information and uplink control information (UCI) together in a time division multiplexing (TDM) manner;
encode a message that includes the multiplexed DMRS information and UCI; and
transmit the message on a carrier frequency that is at or above 52.6 gigahertz (GHz).
14. The UE of claim 13 , wherein the message is a physical uplink control channel (PUCCH) message.
15. The UE of claim 13 , wherein the multiplexing of the DMRS information and UCI occurs prior to a discrete Fourier transform (DFT) operation.
16. The UE of claim 13 , wherein the DMRS information and UCI occupy a common frequency domain resource.
17. The UE of claim 13 , wherein the message includes phase tracking reference signal (PT-RS) information.
18. The UE of claim 13 , wherein the UCI spans one or two symbols.
