Abstract

Claims (49)

1. A method comprising:

receiving, from one or more transmission and reception points (TRPs), a physical downlink shared channel (PDSCH) transmission, the PDSCH transmission comprising a first PDSCH transmission and a second PDSCH transmission, wherein the first PDSCH transmission is associated with a first control resource set (CORESET) scheduling the first PDSCH transmission, and wherein the second PDSCH transmission is associated with a second CORESET scheduling the second PDSCH transmission;

determining, for a first hybrid automatic repeat request-acknowledgement (HARQ-ACK) associated with the first CORESET, a first TRP index value in accordance with the first CORESET scheduling the first PDSCH transmission;

determining, for a second HARQ-ACK associated with the second CORESET, a second TRP index value in accordance with the second CORESET scheduling the second PDSCH transmission;

determining, that the first HARQ-ACK is scheduled to be transmitted in a first a physical uplink control channel (PUCCH) transmission;

determining that the first PUCCH transmission overlaps in time with a first physical uplink shared channel (PUSCH) transmission associated with the second TRP index value;

determining to drop the first PUCCH transmission or the first PUSCH transmission; and

transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value, wherein the transmitting comprises using the first TRP index value and the second TRP index value for HARQ-ACK codebook construction.

2. The method of claim 1 , wherein determining the first TRP index value comprises using a default value for the first TRP index value based on the TRP first index value not being provided by a network.

3. The method of claim 1 , wherein determining the first TRP index value comprises using a CORESET index parameter configured by a radio resource control (RRC) layer.

4. The method of claim 3 , wherein the first TRP index value is indicated by a ConfiguredGrantConfig information element provided by the RRC layer.

5. The method of claim 1 , further comprising:

transmitting, on PUCCH or PUSCH, semi-persistent channel state information based on the first TRP index configured by a radio resource control (RRC) layer.

6. The method of claim 1 , wherein receiving the PDSCH transmission comprises receiving transmissions from multiple TRPs.

7. The method of claim 1 , wherein transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value comprises:

determining that the first PUCCH transmission overlaps in time with a second PUSCH transmission associated with the first TRP index value;

dropping the first PUCCH transmission;

multiplexing the first HARQ-ACK with the second PUSCH transmission; and

transmitting the second PUSCH transmission.

8. The method of claim 7 , wherein transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value and the second TRP index value further comprises:

determining that the second HARQ-ACK is scheduled to be transmitted via a second PUCCH transmission associated with the second TRP index value;

determining that the second PUCCH transmission overlaps in time with the first PUSCH transmission associated with the second TRP index value;

multiplexing the second HARQ-ACK with the first PUSCH transmission; and

transmitting the first PUSCH transmission.

9. The method of claim 1 , wherein transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value comprises:

determining that the first HARQ-ACK is scheduled to be transmitted in a first slot of the first PUCCH transmission associated with the first TRP index value;

determining that the first PUCCH transmission overlaps in time with a second PUSCH transmission associated with the first TRP index value;

in response, dropping the first PUCCH transmission in the first slot; and

transmitting the first HARQ-ACK in a second PUCCH transmission during a second slot.

10. The method of claim 1 , wherein transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value comprises:

determining that the first HARQ-ACK is scheduled to be transmitted in a first slot of the first PUCCH transmission associated with the first TRP index value;

determining that the first PUCCH transmission overlaps in time with a second PUSCH transmission associated with the first TRP index value;

in response, dropping the first and second PUSCH transmissions during the first slot; and

transmitting the first HARQ-ACK in the first PUCCH transmission during the first slot.

11. A user equipment (UE) comprising:

one or more processors;

circuitry to wirelessly communicate with a network; and

a memory storing instructions that, when executed by the one or more processors, cause the UE to perform operations comprising:

receiving, from one or more transmission and reception points (TRPs), a physical downlink shared channel (PDSCH) transmission, the PDSCH transmission comprising a first PDSCH transmission and a second PDSCH transmission, wherein the first PDSCH transmission is associated with a first control resource set (CORESET) scheduling the first PDSCH transmission, and wherein the second PDSCH transmission is associated with a second CORESET scheduling the second PDSCH transmission;

determining, for a first hybrid automatic repeat request-acknowledgement (HARQ-ACK) associated with the first CORESET, a first TRP index value in accordance with the first CORESET scheduling the first PDSCH transmission, wherein determining the first TRP index value comprises using a CORESET index parameter configured in a ConfiguredGrantConfig information element provided by a radio resource control (RRC) layer;

determining, for a second HARQ-ACK associated with the second CORESET, a second TRP index value in accordance with the second CORESET scheduling the second PDSCH transmission;

determining, that the first HARQ-ACK is scheduled to be transmitted in a first a physical uplink control channel (PUCCH) transmission;

determining that the PUCCH transmission overlaps in time with a first physical uplink shared channel (PUSCH) transmission associated with the second TRP index value;

determining to drop the first PUCCH transmission or the first PUSCH transmission; and

transmitting the first HARQ-ACK and the second HARQ-ACK in accordance with at least one of the first TRP index value or the second TRP index value.

12. A method to be performed by a first access node operating in a multi-node system comprising a plurality of access nodes, the method comprising:

determining a first index value for the first access node, wherein each of the plurality of access nodes is associated with a respective index value;

including the first index value in a ConfiguredGrantConfig information element (IE); and

transmitting, via radio resource control (RRC) signaling, the ConfiguredGrantConfig IE to a user equipment (UE) served by the access node.
