Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive an encoded signal including a set of information blocks. Each information block may include a set of encoded information bits and a set of cyclic redundancy check (CRC) bits. The receiving device may perform a staircase decoding procedure to decode the set of encoded information bits of a selected information block that is part of a subset of the set of information blocks that is within a sliding window. The staircase decoding procedure may include one or more iterations of a decoding process applied to the subset of the set of information blocks. The receiving device may perform, inbetween iterations of the staircase decoding procedure applied to the subset of the set of information blocks within the sliding window, a CRC procedure based on the set of CRC bits in the set of information blocks.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to rate matching for new radio (NR) physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH). In certain aspects, a method includes receiving a rate matching resource (RMR) configuration from a serving cell. The method also includes identifying one or more first resource elements (REs) to be rate matched around at least in part based on a transmission numerology associated with the RMR configuration, wherein the one or more first REs are used for reference signal (RS) transmission in the serving cell or a neighboring cell. The method further includes mapping a physical downlink shared channel (PDSCH) to one or more second REs not including the first REs.

Abstract: A configuration for reporting OOD samples for neural network optimization. The apparatus receives, from a base station, a configuration to report an OOD dataset for a machine learning model. The apparatus detects an occurrence of one or more OOD events. The apparatus reports the OOD dataset comprising the one or more OOD events based on the configuration to report OOD dataset. The apparatus receives, from the base station, an update to the machine learning model. The OOD dataset may comprise raw data related to the one or more OOD events, or may comprise extracted latent data corresponding to features of raw data related to the one or more OOD events.

Abstract: Apparatus, methods, and computer-readable media for network coding for handover are disclosed herein. A base station (BS) transmits a first group of encoded packets to a first road side unit (RSU) over a first radio access network (RAN) interface. The BS initiates a handover procedure between the first RSU and a second RSU. The BS receives, from the first RSU, a release acknowledgment associated with the handover procedure and feedback associated with the first group of encoded packets. The BS transmits network coding level information to the second RSU over a second RAN interface based on the feedback. The network coding level information indicates a number of missing encoded packets within the first group of encoded packets for the second RSU to transmit to the UE. The BS transmits, to the UE, a second group of encoded packets associated with the number of missing encoded packets at the second RSU.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, encoded packets that are encoded using network coding. The encoded packets may be associated with source packets that represent a data set. The UE may attempt to recover the source packets from the encoded packets received from the base station. Upon failing to recover the source packets, the UE may transmit, over a sidelink channel, a message requesting sidelink assistance in recovering the source packets.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement multiple autoencoders for communications. A wireless device may select an autoencoder to use for communications based on a size parameter for a message. For example, a user equipment (UE) may receive a grant from a base station indicating a size parameter for communicating a message. The UE and base station may determine, from a set of neural network (NN)-based encoders configured at the UE, an NN-based encoder corresponding to the size parameter. The UE may communicate the message with the base station according to the grant and based on the determined NN-encoder. In some examples, the UE and base station may determine a number of resource segments from a set of resources allocated for communication and may determine respective NN-based encoders for the different resource segments.

Abstract: Methods, systems, and devices for wireless communications are described. An encoding device (e.g., a base station or user equipment (UE)) may communicate, with a decoding device (e.g., a UE or base station), an indication of a set of encoding symbol identifiers via a control channel. The encoding device may transmit a set of packets associated with a rateless code via a data channel, where each of the set of packets includes an encoding symbol. The decoding device may decode the set of encoding symbols based on the set of encoding symbol identifiers.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting a channel state information (CSI) report from a user equipment (UE). The CSI report may be a UE initiated CSI report or may be based on a downlink grant. The UE may receive a downlink grant scheduling a physical downlink shared channel (PDSCH) and a demodulation reference signal (DMRS). The UE may determine to report a CSI in response to a measurement of a downlink measurement resource or in response to the downlink grant requesting the CSI. The UE may determine a reserved uplink resource on which to report the CSI. The UE may transmit a CSI report on the reserved uplink resource.
