Abstract

Certain aspects of the present disclosure provide techniques for configuring and reporting channel state information for resources with different periodicities. A method that may be performed by a user equipment includes receiving a channel state information (CSI) report setting associated with at least one resource setting that indicates a first group of one or more CSI reference signal (CSI-RS) or synchronization signal block (SSB) resources and a second group of one or more CSI-RS or SSB resources, the first group of one or more CSI-RS or SSB resources having a different periodicity than the second group of one or more CSI-RS or SSB resources; and reporting CSI associated with the first group, the second group, or the first group and the second group of one or more monitored CSI-RS or SSB resources.

First claim

What is claimed is:

1 . An apparatus for wireless communication, comprising:
a memory; and a processor coupled to the memory, the processor being configured to:
receive a channel state information (CSI) report setting associated with at least one resource setting that indicates a first group of one or more CSI reference signal (CSI-RS) or synchronization signal block (SSB) resources and a second group of one or more CSI-RS or SSB resources, the first group of one or more CSI-RS or SSB resources having a different periodicity than the second group of one or more CSI-RS or SSB resources, and
report CSI associated with the first group, the second group, or the first group and the second group of one or more monitored CSI-RS or SSB resources.

2 . The apparatus of claim 1 , further comprising:
a transceiver coupled to the processor and the memory, wherein the transceiver is configured to receive the CSI report setting and report the CSI; and wherein the first group of one or more CSI-RS or SSB resources has a different number of resources than the second group of one or more CSI-RS or SSB resources.

3 . The apparatus of claim 1 , wherein the processor is further configured to:
receive the CSI report setting, which further indicates to report a reference signal received power (RSRP) associated with one or more CSI-RS or SSB resources in at least one of the first group of one or more CSI-RS or SSB resources or the second group of one or more CSI-RS or SSB resources, and report the CSI indicating the RSRP associated with the one or more CSI-RS or SSB resources.

4 . The apparatus of claim 1 , wherein the processor is further configured to transmit an indication that the apparatus has a capability to report measurements associated with the first group and the second group of one or more CSI-RS or SSB resources having different periodicities.

5 . The apparatus of claim 1 , wherein the processor is further configured to receive signaling indicating that the CSI report setting identifies the first group of one or more CSI-RS or SSB resources and the second group of one or more CSI-RS or SSB resources.

6 . The apparatus of claim 1 , wherein each resource in the second group of one or more CSI-RS or SSB resources is associated with a plurality of resources in the first group of one or more CSI-RS or SSB resources.

7 . The apparatus of claim 1 , wherein the CSI report setting identifies a CSI resource set indicating the first group of one or more CSI-RS or SSB resources and the second group of one or more CSI-RS or SSB resources.

8 . The apparatus of claim 1 , wherein the CSI report setting identifies a first CSI resource set indicating the first group of one or more CSI-RS or SSB resources and a second CSI resource set indicating the second group of one or more CSI-RS or SSB resources.

9 . The apparatus of claim 1 , wherein:
the CSI report setting includes a first CSI report setting indicating the first group of one or more CSI-RS or SSB resources and a second CSI report setting indicating the second group of one or more CSI-RS or SSB resources; and the second CSI report setting identifies that the first CSI report setting is associated with the second CSI report setting.

10 . The apparatus of claim 1 , wherein the processor is further configured to:
receive signaling indicating one or more quasi co-location (QCL) relationships associated with the second group of one or more CSI-RS or SSB resources and the first group of one or more CSI-RS or SSB resources; and each resource in the second group of one or more CSI-RS or SSB resources is associated with a plurality of resources in the first group of one or more CSI-RS or SSB resources based at least in part on the one or more QCL relationships.

11 . The apparatus of claim 1 , wherein the processor is further configured to receive signaling that includes:
a first indication indicating that properties for a plurality of resources in the first group of one or more CSI-RS or SSB resources are based on one or more measurements for at least one resource in the second group of one or more CSI-RS or SSB resources; a second indication indicating that the at least one resource in the second group of one or more CSI-RS or SSB resources corresponds to a linear combination of the plurality of resources in the first group of one or more CSI-RS or SSB resources; a third indication indicating that the at least one resource in the second group of one or more CSI-RS or SSB resources corresponds to a non-linear combination of the plurality of resources in the first group of one or more CSI-RS or SSB resources; a fourth indication indicating that offset values for the plurality of resources in the first group of one or more CSI-RS or SSB resources are in terms of an angular metric relative to the at least one resource in the second group of one or more CSI-RS or SSB resources; or a combination thereof.

12 . The apparatus of claim 1 , wherein the CSI comprises one or more measurements associated with one or more resources in at least one of the first group of one or more CSI-RS or SSB resources or the second group of one or more CSI-RS or SSB resources.

13 . The apparatus of claim 1 , wherein the CSI comprises one or more measurements associated with one or more resources only in the second group of one or more CSI-RS or SSB resources, wherein the second group of one or more CSI-RS or SSB resources has a shorter periodicity than the first group of one or more CSI-RS or SSB resources.

14 . The apparatus of claim 1 , wherein the processor is further configured to:
process the sf for simultaneous CSI calculations, wherein a number for the simultaneous CSI calculations associated with the CSI report setting is based at least in part on:
a number of resources in at least one of the first group of one or more CSI-RS or SSB resources or the second group of one or more CSI-RS or SSB resources,
a periodicity for at least one of the first group of one or more CSI-RS or SSB resources or the second group of one or more CSI-RS or SSB resources, or
a number of measurements to be reported for at least one of the first group of one or more CSI-RS or SSB resources or the second group of one or more CSI-RS or SSB resources.

15 . An apparatus for wireless communication, comprising:
a memory; and a processor coupled to the memory, the processor being configured to:
send, to a user equipment (UE), a channel state information (CSI) report setting associated with at least one resource setting indicating a first group of one or more CSI reference signal (CSI-RS) or synchronization signal block (SSB) resources and a second group of one or more CSI-RS or SSB resources for measuring CSI, the first group of one or more CSI-RS or SSB resources having a different periodicity than the second group of one or more CSI-RS or SSB resources,
send one or more signals associated with the first group, the second group, or the first group and the second group of one or more CSI-RS or SSB resources, and
obtain, from the UE, CSI associated with at least one of the one or more signals.

16 . The apparatus of claim 15 , further comprising:
a transceiver coupled to the processor and the memory, wherein the transceiver is configured to send the CSI report setting, send the one more signals, and obtain the CSI; and wherein the first group of one or more CSI-RS or SSB resources has a different number of resources than the second group of one or more CSI-RS or SSB resources.
