Abstract: 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.

Abstract: Systems, devices, and techniques for wireless communications based on one or more transmission configuration indicator (TCI) states are described. A described technique performed by a user equipment (UE) includes receiving a first downlink channel based on a current TCI state; receiving a physical downlink shared channel (PDSCH) in a first slot, the PDSCH carrying a radio resource control (RRC) activation command in the first slot, the RRC activation command indicating a switch to a target TCI state; waiting until an end of a switching period triggered by the RRC activation command to use the target TCI state, the switching period being based on a RRC processing delay; and receiving, based on the end of the switching period, a second downlink channel based on the target TCI state in a second slot.

Abstract: Systems, devices, and techniques for measuring and reporting cross-link interference (CLI) are described. A described technique includes determining, by a first wireless device, whether to perform a CLI measurement; determining a quantity of activated transmission configuration indicator (TCI) states associated with a second wireless device; performing the CLI measurement based on the quantity of activated TCI states; and transmitting a CLI report in response to the CLI measurement.

Abstract: Logic may receive an initial communication from a user device, the initial communication comprising capabilities. Logic may determine, based on an indication of a capability to support new radio frequency layers from the capabilities for the user device, a measurement gap configuration for the new radio frequency layers and a measurement gap configuration for a channel state information reference signal. Logic may send a frame with a preamble to a physical layer comprising the measurement gap configuration. Logic may send an initial communication to a physical layer, wherein the initial communication comprises capabilities for a user device. Logic may decode downlink data with a measurement gap configuration. And logic may parse the measurement gap configuration to determine at least one measurement gap identification and at least one offset for the new radio frequency layers and a channel state information reference signal.
