Abstract
A UE may be configured to receive an indication of a CSI-RS configuration. The CSI-RS configuration may be received from a network entity. The CSI-RS configuration may include at least one CSI-RS RB group associated with CDM for a set of CSI-RSs. The at least one CSI-RS RB group may correspond to at least one of a plurality of RBs in a frequency domain or a plurality of slots in a time domain. The UE may be configured to receive the set of CSI-RSs based on the CSI-RS configuration and the CDM for the set of CSI-RSs. The CDM for the set of CSI-RSs may be associated with at least one of the plurality of RBs or the plurality of slots.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- receive an indication of a channel state information (CSI) reference signal (CSI-RS) configuration, wherein the CSI-RS configuration includes at least one CSI-RS resource block (RB) group associated with code division multiplexing (CDM) for a set of CSI-RSs, wherein the at least one CSI-RS RB group corresponds to at least one of a plurality of RBs in a frequency domain or a plurality of slots in a time domain;
- and
- receive the set of CSI-RSs based on the CSI-RS configuration and the CDM for the set of CSI-RSs, wherein the CDM for the set of CSI-RSs is associated with at least one of the plurality of RBs or the plurality of slots.
An apparatus for wireless communication at a network entity, comprising:
- a memory;
