AI Technical Summary
Technical Problem
In multi-USIM scenarios, there are splitting problems with CSI-RS resource configuration and reporting of UEs, resulting in performance degradation and resource unreliability.
Method used
By defining and managing shared resources and non-shared resources between the UE and the network, using user equipment auxiliary information and channel status information reporting mechanisms, the configuration and use of CSI-RS resources are dynamically adjusted to ensure effective sharing and optimization of resources.
Benefits of technology
The reliability and efficiency of CSI-RS resource configuration and reporting in multiple USIM scenarios are realized, resource crossover and performance degradation are avoided, and the overall performance of the network is improved.

Abstract
Various techniques are provided for indicating, from a plurality of Universal Subscriber Identity Module (MUSIM) user equipments (UEs), a capability to a first network node associated with a first USIM of the MUSIM UE, the capability indicating a number of shared resources that can be partitioned between the first network node and a second network node of a second USIM corresponding to the MUSIM UE, receiving, by the MUSIM UE from the first network node, a configuration identifying non-shared resources and shared resources based on MUSIM UE resources partitioned between the first USIM and the second USIM, and reporting, from the MUSIM UE to the first network node, at least one of channel state information for channel resources that are not shared between the first USIM and the second USIM and an absence indicating reporting of resources for use by the second USIM.
