Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may perform channel state information (CSI) estimation on multiple links (e.g., a Uu link and a sidelink) without excessive power expenditures. The UE may report a CSI processing unit (CPU) capability to a network device. The CPU capability information may include separate CPU capabilities for separate links, or a single CPU capability for multiple links. The network device, the UE, or both, may trigger CSI estimation procedures that do not exceed the reported CPU capability, or may otherwise prioritize CSI estimation procedures based on the CPU capability. The UE may then perform CSI estimation procedures according to one or more rules associated with the CPU capabilities. In some examples, such rules may be explicitly signaled to the UE, or may be included in one or more standard documents.
