Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources. For example, the multiple CSI reports may include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type. The UE may select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on a first priority associated with the first service type and a second priority associated with the second service type. Accordingly, the UE may transmit, in the slot, one or more PUCCH transmissions that include the one or more selected CSI reports. Numerous other aspects are provided.

Claims24

Dependent claims

A method of wireless communication performed by a user equipment (UE), comprising:

identifying multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources, wherein the multiple CSI reports include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type;
selecting, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on whether the UE is configured with a radio resource control (RRC) parameter that specifies resources for multiplexing CSI reports, a first priority associated with the first service type, and a second priority associated with the second service type,
wherein the one or more CSI reports associated with the first service type do not overlap in time with the one or more CSI reports associated with the second service type in the slot, and
wherein selecting the one or more CSI reports to be transmitted in the slot includes:
dropping the one or more CSI reports associated with the first service type based at least in part on the one or more CSI reports associated with the second service type being scheduled for transmission in the slot, regardless of whether the one or more CSI reports associated with the first service type overlap in time with the one or more CSI reports associated with the second service type in the slot, and based at least in part on determining that the first priority associated with the first service type is lower than the second priority associated with the second service type;
and
selecting the one or more CSI reports to be transmitted in the slot, from the one or more CSI reports associated with the second service type, based on one or more levels of a priority hierarchy associated with the respective PUCCH resources,
the one or more levels of the priority hierarchy corresponding to an evaluation of at least one of a cell identifier, a CSI report configuration identifier, or CSI report type;
and
transmitting, in the slot based at least in part on the RRC parameter, one or more PUCCH transmissions that include the one or more selected CSI reports.

7 more elements

A user equipment (UE) for wireless communication, comprising:

a memory;
and
one or more processors coupled to the memory, the one or more processors configured to:
identify multiple channel state information (CSI) reports scheduled to be transmitted in a slot on respective physical uplink control channel (PUCCH) resources, wherein the multiple CSI reports include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type;
select, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on whether the UE is configured with a radio resource control (RRC) parameter that specifies resources for multiplexing the CSI reports, a first priority associated with the first service type, and a second priority associated with the second service type,
wherein the one or more CSI reports associated with the first service type do not overlap in time with the one or more CSI reports associated with the second service type in the slot, and
wherein the one or more processors, when selecting the one or more CSI reports to be transmitted in the slot, are further configured to:
drop the one or more CSI reports associated with the first service type based at least in part on the one or more CSI reports associated with the second service type being scheduled for transmission in the slot, regardless of whether the one or more CSI reports associated with the first service type overlap in time with the one or more CSI reports associated with the second service type in the slot, and based at least in part on determining that the first priority associated with the first service type is lower than the second priority associated with the second service type;
and
select the one or more CSI reports to be transmitted in the slot, from the one or more CSI reports associated with the second service type, based on one or more levels of a priority hierarchy associated with the respective PUCCH resources,
the one or more levels of the priority hierarchy corresponding to an evaluation of at least one of a cell identifier, a CSI report configuration identifier, or CSI report type;
and
transmit, in the slot based at least in part on the RRC parameter, one or more PUCCH transmissions that include the one or more selected CSI reports.

10 more elements

A method of wireless communication performed by a network entity, comprising:

identifying multiple channel state information (CSI) reports that a user equipment (UE) is scheduled to transmit in a slot on respective physical uplink control channel (PUCCH) resources, wherein the multiple CSI reports include one or more CSI reports associated with a first service type and one or more CSI reports associated with a second service type;
determining, from the multiple CSI reports, one or more CSI reports to be transmitted in the slot based at least in part on whether the UE is configured with a radio resource control (RRC) parameter that specifies resources for multiplexing the CSI reports, a first priority associated with the first service type, and a second priority associated with the second service type,
wherein the one or more CSI reports associated with the first service type do not overlap in time with the one or more CSI reports associated with the second service type in the slot, and
wherein determining the one or more CSI reports to be transmitted in the slot includes:
determining that the UE is to drop the one or more CSI reports associated with the first service type based at least in part on the one or more CSI reports associated with the second service type being scheduled for transmission in the slot, regardless of whether the one or more CSI reports associated with the first service type overlap in time with the one or more CSI reports associated with the second service type in the slot, and based at least in part on the first priority associated with the first service type being lower than the second priority associated with the second service type;
and
determining the one or more CSI reports to be transmitted in the slot from the one or more CSI reports associated with the second service type, based on one or more levels of a priority hierarchy associated with the respective PUCCH resources,
the one or more levels of the priority hierarchy corresponding to an evaluation of at least one of a cell identifier, a CSI report configuration identifier, or CSI report type;
and
receiving, in the slot, one or more PUCCH transmissions that include the one or more CSI reports.
