Abstract
Aspects presented herein may improve the accuracy and/or the efficiency of HARQ feedback for a UE communicating with a base station or multiple TRPs using multiple antenna panels. In one aspect, an apparatus receives DCI scheduling a PDSCH to be received by a first plurality of panels and indicating a second plurality of PUCCH repetitions for providing ACK/NACK feedback. The apparatus receives the PDSCH through the first plurality of panels. The apparatus transmits ACK/NACK feedback in the indicated second plurality of PUCCH repetitions based on the received PDSCH.
Claims25
A method of wireless communication of a user equipment (UE), comprising:
- receiving downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) to be received by a plurality of panels and indicating a plurality of physical uplink control channel (PUCCH) repetitions for providing acknowledgment (ACK)/negative ACK (NACK) feedback, wherein the DCI comprises an ACK/NACK feedback timing indicator that includes a single offset value (K1), wherein each of the plurality of panels is associated with a panel-specific offset value;
- receiving the PDSCH through the plurality of panels;
- and
- transmitting ACK/NACK feedback in the indicated plurality of PUCCH repetitions based on (1) the received PDSCH, (2) the single offset value (K1), and (3) the panel-specific offset value from at least one of the plurality of panels.
An apparatus for wireless communication of a user equipment (UE), comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to:
- receive downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) to be received by a plurality of panels and indicating a plurality of physical uplink control channel (PUCCH) repetitions for providing acknowledgment (ACK)/negative ACK (NACK) feedback, wherein the DCI comprises an ACK/NACK feedback timing indicator that includes a single offset value (K1), wherein each of the plurality of panels is associated with a panel-specific offset value;
- receive the PDSCH through the plurality of panels;
- and
- transmit ACK/NACK feedback in the indicated plurality of PUCCH repetitions based on (1) the received PDSCH, (2) the single offset value (K1), and (3) the panel-specific offset value from at least one of the plurality of panels.
A method of wireless communication of a base station, comprising:
- transmitting, to a user equipment (UE), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) to be transmitted to a plurality of panels and indicating a plurality of physical uplink control channel (PUCCH) repetitions for receiving acknowledgment (ACK)/negative ACK (NACK) feedback, wherein the DCI comprises an ACK/NACK feedback timing indicator that includes a single offset value (K1), wherein each of the plurality of panels is associated with a panel-specific offset value;
- transmitting the PDSCH to the plurality of panels;
- and
- receiving ACK/NACK feedback in the indicated plurality of PUCCH repetitions based on (1) the transmitted PDSCH, (2) the single offset value (K1), and (3) the panel-specific offset value from at least one of the plurality of panels.
An apparatus for wireless communication of a base station, comprising:
- at least one memory;

- transmit the PDSCH to the plurality of panels;
- and
- receive ACK/NACK feedback in the indicated plurality of PUCCH repetitions based on (1) the transmitted PDSCH, (2) the single offset value (K1), and (3) the panel-specific offset value from at least one of the plurality of panels.
