Multiple slot long physical uplink control channel (PUCCH) design for 5th generation (5G) new radio (NR)
A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine whether an uplink control channel (PUCCH) spans over multiple slots based on a signaling from a base station (gNB). The instructions are also executable to determine a PUCCH location in each slot in a multi-slot PUCCH. The instructions are executable to determine a number of slots in the multi-slot PUCCH. The instructions are further executable to determine whether the multi-slot PUCCH conflicts with a slot format indication (SFI). The instructions are also executable to transmit uplink control information (UCI) on a selected channel.
1. A user equipment (UE), comprising:
a processor; and
memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
determine whether an uplink control channel (PUCCH) spans over multiple slots based on a signaling from a base station (gNB);
determine a PUCCH location in each slot in a multi-slot PUCCH;
determine a number of slots in the multi-slot PUCCH;
determine whether the multi-slot PUCCH conflicts with a slot format indication (SFI); and
transmit uplink control information (UCI) on a selected channel.
2. The UE of claim 1 , wherein the instructions executable to determine the PUCCH location in each slot in the multi-slot PUCCH comprise instructions executable to determine whether each slot includes the same starting and ending positions and duration based on a radio resource control (RRC) configuration.
3. The UE of claim 1 , wherein the instructions executable to determine the PUCCH location in each slot in the multi-slot PUCCH comprise instructions executable to determine whether different slots include different starting and ending positions and durations based on a radio resource control (RRC) configuration.
4. The UE of claim 1 , wherein the instructions executable to determine the PUCCH location in each slot in the multi-slot PUCCH comprise instructions executable to determine whether different slots include different starting and ending positions and durations based on information derived from an SLI and/or a short PUCCH configuration.
5. The UE of claim 1 , wherein the instructions executable to determine the number of slots in the multi-slot PUCCH comprise instructions executable to count a number of slots with long PUCCH allocations.
6. The UE of claim 5 , wherein continuous slots are allocated for frequency division duplexing (FDD), consecutive uplink slots are allocated for slot level time division duplexing (TDD), and a long PUCCH follows a pattern that includes slot gaps.
7. The UE of claim 1 , wherein the instructions executable to determine whether the multi-slot PUCCH conflicts with an SLI comprise instructions executable to determine whether a long PUCCH includes a symbol with a different allocation.
8. The UE of claim 7 , wherein the instructions are further executable to transmit a punctured long PUCCH by dropping conflicting symbols.
9. The UE of claim 7 , wherein the instructions are further executable to drop the long PUCCH in a given slot without extension.
10. The UE of claim 7 , wherein the instructions are further executable to drop the long PUCCH in a given slot and to extend a later slot to maintain the number of slots in the multi-slot PUCCH.
11. A method, comprising:
determining whether an uplink control channel (PUCCH) spans over multiple slots based on a signaling from a base station (gNB);
determining a PUCCH location in each slot in a multi-slot PUCCH;
determining a number of slots in the multi-slot PUCCH;
determining whether the multi-slot PUCCH conflicts with a slot format indication (SFI); and
transmitting uplink control information (UCI) on a selected channel.
12. The method of claim 11 , wherein determining the PUCCH location in each slot in the multi-slot PUCCH comprises determining whether each slot includes the same starting and ending positions and duration based on a radio resource control (RRC) configuration.
13. The method of claim 11 , wherein determining the PUCCH location in each slot in the multi-slot PUCCH comprises determining whether different slots include different starting and ending positions and durations based on a radio resource control (RRC) configuration.
14. The method of claim 11 , wherein determining the PUCCH location in each slot in the multi-slot PUCCH comprises determining whether different slots include different starting and ending positions and durations based on information derived from an SLI and/or a short PUCCH configuration.
15. The method of claim 11 , wherein determining the number of slots in the multi-slot PUCCH comprise counting a number of slots with long PUCCH allocations.
16. The method of claim 15 , wherein continuous slots are allocated for frequency division duplexing (FDD), consecutive uplink slots are allocated for slot level time division duplexing (TDD), and a long PUCCH follows a pattern that includes slot gaps.
17. The method of claim 11 , wherein determining whether the multi-slot PUCCH conflicts with an SLI comprises determining whether a long PUCCH includes a symbol with a different allocation.
18. The method of claim 17 , further comprising transmitting a punctured long PUCCH by dropping conflicting symbols.
19. The method of claim 17 , further comprising dropping the long PUCCH in a given slot without extension.
20. The method of claim 17 , further comprising dropping the long PUCCH in a given slot and to extend a later slot to maintain the number of slots in the multi-slot PUCCH.
