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: This disclosure relates to techniques for dynamically adjusting a number of active receiver chains of a wireless device. Based on communication parameters exchanged with a base station, a device may determine a maximum number of receiver chains needed for data reception during one or more time periods. Such dynamic adjustment may enable power savings.

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.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n−k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Abstract: Methods and devices for a base station acting as a primary cell to perform dual spectrum sharing (DSS) with a first user equipment device (UE) over a 5G NR connection and a second UE over an LTE connection. The first UE establishes the 5G NR connection with the primary cell and one or more secondary cells. One of the secondary cells is configured in the 5G NR connection to provide downlink control information to the UE for the primary cell, to avoid collisions by the primary cell with LTE control transmissions.
