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.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, information indicating one or more of sounding reference signal (SRS) ports selected by the network entity and associated linear combination coefficients, determine subband precoding based at least in part on the selected SRS ports and linear combination coefficient, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station, downlink control information indicating at least a portion of a frequency domain basis vector being applied by the base station for frequency domain precoding of a reference signal scheduled for transmission via a set of antenna ports, receiving, from the base station, the reference signal that is frequency domain precoded in accordance with the at least portion of the frequency domain basis vector via the set of antenna ports, and transmitting, to the base station, a report indicating an antenna port subset of the set of antenna ports and a precoding coefficient for each antenna port of the antenna port subset.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message from a base station, and the configuration message may include an indication of one or more partial bands for channel state information reporting. Each partial band of the one or more partial bands may be less than a system bandwidth and include a plurality of frequency domain units associated with a precoder. The UE may select one or more antenna ports for each partial band of the one or more partial bands based on the configuration message and calculate channel state information including a linear combination of the selected one or more antenna ports for each partial band. The UE may transmit the channel state information including an indication of the selected antenna ports and linear combination coefficients for each partial band of the one or more partial bands
