Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (EMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a New Radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.

Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.
