Abstract: Methods, systems, and devices for signaling in cast-type indication for a wireless communication system may include receiving, at a first user equipment (UE), a first stage sidelink control information (SCI) format from a second UE, decoding the first stage SCI format, determining a second stage SCI format using the decoded first stage SCI format, decoding the second stage SCI format, and determining a sidelink feedback status using the second stage SCI format. The sidelink feedback status may indicate whether sidelink feedback is enabled or not enabled. Second stage SCI content may include a distance setting associated with a communication range between the first UE and the second UE.

Abstract: This disclosure relates to techniques for performing wireless communications including exchanging information related to capability of processing reference signals. A user equipment device may provide capability information to a network. The capability information may indicate a number of reference signal resources that the user equipment device can process in a slot or other defined period of time. The user equipment device and the network may share a common set of definitions, counting rules, and approaches for interpreting the capability information. The network may configure reference signals for the user equipment device.

Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources for an uplink (UL) physical channel for an uplink (UL)-to-downlink (DL) channel occupancy time (COT) sharing to coexist with another radio access technology (RAT). An energy detection (ED) threshold can be selected from the different sets of resource configurations for an UL transmission based on one or more conditions. A gap can be configured between a physical random access control channel (PRACH) transmission and a PUSCH transmission based on one of at least a first value associated with a numerology between the PRACH and the PUSCH and a second value greater than the first value. The UL transmission can be provided based on the ED threshold or the configured conditional gap via the UL physical channel.

Abstract: Apparatuses, systems, and methods for enhanced positioning techniques using configuration and capability signaling in cellular systems. A method may include reporting, to a network node, an indication of one or more user equipment (UE) capability parameters associated with a processing procedure for positioning reference signal (PRS) bandwidth aggregation. The method may include receiving, from the network node and associated with the reported one or more UE capability parameters, a configuration for the processing procedure which supports multiple positioning frequency layer (multi-PFL) processing for aggregation of PRS resources across a plurality of PFLs and further supports one or more PFL groups comprising the plurality of PFLs to be configured on one or more component carriers (CCs). Additionally, respective PRS resources in respective PFL groups may share one or more common parameters and the method may further include performing, based on the received configuration, the processing procedure.

Abstract: Systems, methods, and circuitries are provided for aligning a number of eigen-vectors summarizing channel state information to a number of input nodes of an AI-based CSI feedback compression encoder. In one example, a method includes receiving a channel state information (CSI) report configuration that indicates a number of PRBs; determining a number of subbands and a respective number of PRBs in each respective subband; and generating a plurality of eigen-vectors, wherein one or more of the eigen-vectors summarizes a channel state matrix across a respective subband. A number eigen-vectors in the plurality corresponds to number of inputs of an artificial intelligence (AI) encoder used for CSI feedback compression.
