Abstract: Systems, methods, and circuitries are provided for quantizing artificial intelligence (AI)-based compressed channel state information (CSI) feedback. In one example, a method includes receiving a set of encoder outputs from an AI-based encoder that generates compressed CSI feedback. The method includes optimizing a per-segment vector quantization (VQ) codebook for use in quantizing respective segments of encoder outputs based on the set of encoder outputs. A number of inputs of the VQ codebook and a number of outputs of the VQ codebook are based on a number of bits configured for uplink channel information (UCI) and a number of segments.

Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.

Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: Embodiments herein describe systems, apparatuses, and methods for adapting physical downlink control channel (PDCCH) monitoring behaviors. In some embodiments, a network node and a UE use search space set group switching to change PDCCH monitoring behavior. In some embodiments, a network node and a UE use PDCCH skipping to change PDCCH monitoring behavior. The PDCCH monitoring behavior may be indicated in a downlink control indicator (DCI).

Abstract: A wireless communication system may use enhanced feedback indicating a PDSCH decoding outcome. The enhanced feedback may be in an uplink control information (UCI) and carried over PUCCH or PUSCH. The enhanced feedback may be encoded and divided up into two parts of the UCI. A first payload may be carried in a first part of the UCI and a second payload comprising additional feedback information may be carried in a second part of the UCI.
