Overlapping PUCCH and PUSCH transmission
Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.
1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a radio resource control (RRC) configuration including one or more RRC parameters that indicate to the UE to enable overlapping transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) for a PUCCH group;
configuring the PUSCH and the PUCCH for the overlapping transmission based on the one or more RRC parameters;
transmitting uplink control information (UCI) in a first slot of the PUCCH; and
transmitting data information in a second slot of the PUSCH, the second slot at least partially overlapping with the first slot.
2. The method of claim 1 , wherein the one or more RRC parameters indicate one or more uplink carriers are one or more uplink data carriers, a group of uplink carriers is a group of uplink data carriers, or a first cell includes the one or more uplink data carriers, wherein the first cell is different than a second cell associated with the PUCCH.
3. The method of claim 1 , wherein the PUCCH is associated with a first cell and the PUSCH is associated with a second cell different than the first cell.
4. The method of claim 3 , further comprising:
receiving a first control resource set (CORESET) having a first CORESET index and a second CORESET having a second CORESET index;
detecting a first downlink control information (DCI) format in a first physical downlink control channel (PDCCH) received in the first CORESET and a second DCI format in a second PDCCH received in the second CORESET;
triggering the transmission of the PUCCH associated with the first cell based on detecting the first DCI format; and
triggering the transmission of the PUSCH associated with the second cell based on detecting the second DCI format.
5. The method of claim 3 , wherein the first cell is a Primary Cell (PCell) or a Primary Secondary Cell (PSCell) and the second cell is a Secondary Cell (SCell).
6. The method of claim 3 , further comprising transmitting second control information in a third slot via the second cell.
7. The method of claim 6 , wherein transmitting the second control information comprises transmitting the second control information in the PUSCH, wherein the second slot and the third slot at least partially overlap with the first slot.
8. The method of claim 6 , wherein transmitting the second control information further comprises transmitting the second control information in the PUCCH, wherein the second slot at least partially overlaps with the first slot and with the third slot.
9. The method of claim 1 , wherein the one or more RRC parameters comprise a 1-bit RRC parameter that indicates to the UE to enable overlapping transmission of the PUCCH and the PUSCH.
10. The method of claim 1 , further comprising:
refraining from transmitting the UCI in the PUSCH.
11. The method of claim 1 , wherein transmitting the UCI in the first slot of the PUCCH comprises transmitting the UCI in the first slot of the PUCCH based on a CORESETPoolIndex; and
wherein transmitting the data information in the second slot of the PUSCH comprises transmitting the data information in the second slot of the PUSCH based on the CORESETPoolIndex, the second slot at least partially overlapping with the first slot.
12. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors coupled to the memory, wherein the one or more processors are configured to:
receive a radio resource control (RRC) configuration including one or more RRC parameters that indicate to the UE to enable overlapping transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) for a PUCCH group;
configure the PUSCH and the PUCCH for the overlapping transmission based on the one or more RRC parameters;
transmit uplink control information (UCI) in a first slot of the PUCCH; and
transmit data information in a second slot of the PUSCH, the second slot at least partially overlapping with the first slot.
13. The UE of claim 12 , wherein the one or more RRC parameters indicate one or more uplink carriers are one or more uplink data carriers, a group of uplink carriers is a group of uplink data carriers, or a first cell includes the one or more uplink data carriers, wherein the first cell is different than a second cell associated with the PUCCH.
14. The UE of claim 12 , wherein the PUCCH is associated with a first cell and the PUSCH is associated with a second cell different than the first cell.
15. The UE of claim 14 , wherein the one or more processors are configured to:
receive a first control resource set (CORESET) having a first CORESET index and a second CORESET having a second CORESET index;
detect a first downlink control information (DCI) format in a first physical downlink control channel (PDCCH) received in the first CORESET and a second DCI format in a second PDCCH received in the second CORESET;
trigger the transmission of the PUCCH associated with the first cell based on detecting the first DCI format; and
trigger the transmission of the PUSCH associated with the second cell based on detecting the second DCI format.
16. The UE of claim 14 , wherein the first cell is a Primary Cell (PCell) or a Primary Secondary Cell (PSCell) and the second cell is a Secondary Cell (SCell).
17. The UE of claim 14 , wherein the one or more processors are further configured to transmit second control information in a third slot via the second cell, wherein the UCI is first control information.
18. The UE of claim 17 , wherein, to transmit the second control information, the one or more processors are configured to transmit the second control information in the PUSCH, wherein the second slot and the third slot at least partially overlap with the first slot.
19. The UE of claim 17 , wherein, to transmit the second control information, the one or more processors are configured to transmit the second control information in the PUCCH, wherein the second slot at least partially overlaps with the first slot and with the third slot.
20. The UE of claim 12 , wherein the one or more RRC parameters comprise a 1-bit RRC parameter that indicates to the UE to enable overlapping transmission of the PUCCH and the PUSCH.
