Abstract

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 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 demodulation reference signals (DMRS) structure in the configured multi-slot PUCCH. The instructions are further executable to determine a frequency hopping method of the configured multi-slot PUCCH. The instructions are additionally executable to determine uplink control information (UCI) encoding and loading methods on the configured multi-slot PUCCH. The instructions are also executable to determine a resource of a control channel for UCI feedback. The instructions are further executable to transmit UCI on a selected channel.

First claim

What is claimed is:

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 an uplink control channel (PUCCH) spans over multiple slots based on a signaling from a base station (gNB);
determine a demodulation reference signals (DMRS) structure in the configured multi-slot PUCCH;
determine a frequency hopping method of the configured multi-slot PUCCH;
determine UCI encoding and loading methods on the configured multi-slot PUCCH;
determine a resource of a control channel for UCI feedback; and
transmit UCI on a selected channel.

2 . The UE of claim 1 , wherein the number of PUCCH symbols in each slot of a multi-slot uplink control channel (PUCCH) is greater than or equal to 4, and the reference symbol (RS) pattern in each slot is determined on a per slots basis by a long PUCCH format of a given the number of PUCCH symbols in the slot.

3 . The UE of claim 1 , wherein the number of PUCCH symbols may be the same in each slot of a multi-slot uplink control channel (PUCCH), and the same PUCCH symbol location may be allocated in each slot.

4 . The UE of claim 1 , wherein UCI encoded bits are rate matched and loaded to all to PUCCH UCI carrying symbols of each slot of the long PUCCH separately. If the number of PUCCH symbols in each slot is the same, the PUCCH format and encoded UCI in each slot is repeated in multiple slots.

5 . The UE of claim 1 , wherein the frequency hopping is applied at slot boundaries in a multi-slot PUCCH.

6 . The UE of claim 1 , wherein the frequency hopping is applied within each slot in a multi-slot PUCCH.

7 . The UE of claim 1 , wherein whether the frequency hopping is inter-slot or intra-slot can be configured by higher layer signaling for a multi-slot PUCCH.

8 . A base station (gNB), comprising:
a processor; and memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
determine an uplink control channel (PUCCH) spans over multiple slots;
determine a demodulation reference signals (DMRS) structure in the configured multi-slot PUCCH;
determine a frequency hopping method of the configured multi-slot PUCCH;
determine UCI encoding and loading methods on the configured multi-slot PUCCH;
determine a resource of a control channel for UCI feedback; and
receive UCI on a selected channel.

9 . The gNB of claim 8 , wherein the number of PUCCH symbols in each slot of a multi-slot uplink control channel (PUCCH) is greater than or equal to 4, and the reference symbol (RS) pattern in each slot is determined on a per slots basis by a long PUCCH format of a given the number of PUCCH symbols in the slot.

10 . The UE of claim 8 , wherein the number of PUCCH symbols may be the same in each slot of a multi-slot uplink control channel (PUCCH), and the same PUCCH symbol location may be allocated in each slot.

11 . The gNB of claim 8 , wherein UCI encoded bits are rate matched and loaded to all to PUCCH UCI carrying symbols of each slot of the long PUCCH separately. If the number of PUCCH symbols in each slot is the same, the PUCCH format and encoded UCI in each slot is repeated in multiple slots.

12 . The gNB of claim 8 , wherein the frequency hopping is applied at slot boundaries in a multi-slot PUCCH.

13 . The gNB of claim 8 , wherein the frequency hopping is applied within each slot in a multi-slot PUCCH.

14 . The gNB of claim 8 , wherein whether the frequency hopping is inter-slot or intra-slot can be configured by higher layer signaling for a multi-slot PUCCH.

15 . A method by a user equipment (UE), comprising:
determining an uplink control channel (PUCCH) spans over multiple slots based on a signaling from a base station (gNB); determining a demodulation reference signals (DMRS) structure in the configured multi-slot PUCCH; determining a frequency hopping method of the configured multi-slot PUCCH; determining UCI encoding and loading methods on the configured multi-slot PUCCH; determining a resource of a control channel for UCI feedback; and transmitting UCI on a selected channel.

16 . A method by a base station (gNB), comprising:
determining an uplink control channel (PUCCH) spans over multiple slots; determining a demodulation reference signals (DMRS) structure in the configured multi-slot PUCCH; determining a frequency hopping method of the configured multi-slot PUCCH; determining UCI encoding and loading methods on the configured multi-slot PUCCH; determining a resource of a control channel for UCI feedback; and receiving UCI on a selected channel.
