Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions. The UE may perform joint channel estimation using the DMRSs in the multiple PDSCH reception occasions. The UE may transmit a feedback message after a processing time that includes an offset associated with the joint channel estimation, wherein the processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message. Numerous other aspects are described.
Claims30
A user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions;
- perform joint channel estimation using the DMRSs in the multiple PDSCH reception occasions;
- and
- transmit a feedback message after a PDSCH processing time including an offset that is associated with the joint channel estimation and that extends the PDSCH processing time associated with the joint channel estimation, wherein the PDSCH processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message.
A network entity for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit, for a user equipment (UE), demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions;
- and
- receive a feedback message based at least in part on a PDSCH processing time at the UE, wherein the PDSCH processing time includes an offset that is associated with joint channel estimation of the DMRSs and that extends the PDSCH processing time associated with the joint channel estimation, and wherein the PDSCH processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions;
- performing joint channel estimation using the DMRSs in the multiple PDSCH reception occasions;
- and
- transmitting a feedback message after a PDSCH processing time including an offset that is associated with the joint channel estimation and that extends the PDSCH processing time associated with the joint channel estimation, wherein the PDSCH processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message.
A method of wireless communication performed by a network entity, comprising:
- transmitting, for a user equipment (UE), demodulation reference signals (DMRSs) in multiple physical downlink shared channel (PDSCH) reception occasions;
- and
- receiving a feedback message based at least in part on a PDSCH processing time at the UE, wherein the PDSCH processing time includes an offset that is associated with joint channel estimation of the DMRSs and that extends the PDSCH processing time associated with the joint channel estimation, and wherein the PDSCH processing time starts after a last symbol of a PDSCH reception occasion of the multiple PDSCH reception occasions and ends before a first symbol of the feedback message.
