Multiple slot long physical uplink control channel (PUCCH) design for 5th generation (5G) new radio (NR)
View Patent ↗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.
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 method of a frequency hopping for the configured multiple slots PUCCH; and
transmit uplink control information (UCI) with the frequency hopping, wherein
the number of symbols of the PUCCH is the same in each slot of the multi slots, and
the location of the symbols for the PUCCH is the same in the each slot of the multiple slots.
2. The UE of claim 1 , wherein the number of symbols of the PUCCH in each slot of the multiple slots PUCCH is greater than or equal to 4, and a 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 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, and if the number of symbols of the PUCCH in each slot is the same, the PUCCH format and encoded UCI in each slot is repeated in the multiple slots.
5. The UE of claim 1 , wherein the frequency hopping is applied at slot boundaries in the multiple slots PUCCH.
6. The UE of claim 1 , wherein the frequency hopping is applied within each slot in the multiple slots 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 the multiple slots 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:
transmit, to a user equipment (UE), a signaling, an uplink control channel (PUCCH) spans over multiple slots being determined based on the signaling; and
receive uplink control information (UCI) with the frequency hopping for the configured multiple slots PUCCH, wherein
the number of symbols of the PUCCH is the same in each slot of the multiple slots, and
the location of the symbols for the PUCCH is the same in the each slot of the multiple slots.
9. The gNB of claim 8 , wherein the number of symbols of the PUCCH in each slot of the multiple slots PUCCH is greater than or equal to 4, and a 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 gNB of claim 8 , wherein 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, and if the number of symbols of the PUCCH in each slot is the same, the PUCCH format and encoded UCI in each slot is repeated in the multiple slots.
12. The gNB of claim 8 , wherein the frequency hopping is applied at slot boundaries in the multiple slots PUCCH.
13. The gNB of claim 8 , wherein the frequency hopping is applied within each slot in the multiple slots 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 the multiple slots 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 method of a frequency hopping for the configured multiple slots PUCCH; and
transmitting uplink control information (UCI) with the frequency hopping, wherein
the number of symbols of the PUCCH is the same in each slot of the multi slots, and
the location of the symbols for the PUCCH is the same in the each slot of the multiple slots.
16. A method by a base station (gNB), comprising:
transmit, to a user equipment (UE), a signaling, an uplink control channel (PUCCH) spans over multiple slots being determined based on the signaling; and
receiving uplink control information (UCI) with the frequency hopping for the configured multiple slots PUCCH, wherein
the number of symbols of the PUCCH is the same in each slot of the multiple slots, and
the location of the symbols for the PUCCH is the same in the each slot of the multiple slots.
