摘要： A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

摘要： Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt−J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.
