Abstract: Methods, systems, devices, and apparatuses that support rateless polar codes are used to provide for retransmissions in cases that a codeword is encoded using a rateless polar code. For example, a first wireless device may transmit, to a second wireless device, a codeword corresponding to a set of information bits encoded using a rateless polar code. In cases where the first wireless device identifies that the second wireless device failed to decode one or more of the information bits, the first wireless device may select a subset of the encoder input bits for retransmission based on an order of a likelihood of error associated with a set of bit-channels used for encoding the set of information bits using the polar code. The number of retransmitted encoder input bits may be based further on a gap to capacity calculated by the first wireless device and/or the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of one or more masking parameters associated with an inpainting scheme to a receiving device. The UE may remove, according to the one or more masking parameters of the inpainting scheme, a portion of image data from an image to obtain a masked image, the masked image having a smaller amount of image data than the image. The UE may compress, according to a compression scheme, the masked image to obtain a compressed image, the compressed image having a smaller amount of image data than the masked image based at least in part on the compression. The UE may transmit the compressed image to the receiving device.

Abstract: Certain aspects of the present disclosure provide techniques for Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining a minimal list size to use in list decoding operations for reducing resource consumption (e.g., compute, memory, and power) at a decoder. A method includes receiving a codeword comprising a plurality of channel bits encoded with an error-correcting code, the plurality of channel bits comprising, at least, a plurality of information bits, determining a payload size of the codeword, determining a channel capacity metric for the plurality of channel bits, determining a minimal list size for a list decoding operation based on at least the payload size and the channel capacity metric; and performing the list decoding operation on the codeword based on the minimal list size to obtain the plurality of information bits.

Abstract: Methods, systems, and devices for wireless communications are described. Systematic polar codes may be used for the transmission of information bits to a wireless communications device, such as for extended reality (XR) applications, online video application, or other applications. In such cases, information bits of a data stream may be sorted based on priority or importance. Additionally, in accordance with the use of systematic polar coding, bit-channels may be sorted by protection level, and the sorted bits may be mapped to the most highly protected bit-channels (e.g., based on the importance of the bits). The mapped bits may be encoded using a systematic polar encoder to generate a codeword, and the codeword may be transmitted to another wireless communications device.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein relate to user equipment (UE) reporting for a rake receiver configuration and setting transmission parameters. The UE receives, from a network entity, a request to provide a report indicative of one or more capability parameters associated with a rake receiver of the UE. The UE transmits, to the network entity, the report based on the one or more capability parameters. The UE receives from the network entity, signaling indicating a configuration to be applied to the rake receiver based at least in part on the report.

Abstract: Aspects relate to mechanisms for mutual information (MI)-based physical downlink control channel (PDCCH) candidate pruning. A UE may receive a plurality of PDCCH candidates in a search space. Each of the PDCCH candidates includes a demodulation reference signal (DMRS) generated with the same scrambling seed and control information generated with one or more respective UE-specific non-transparent precoding parameters. The UE can prune the PDCCH candidates to identify at least one PDCCH candidate for decoding by generating the log-likelihood ratio (LLR) magnitudes of demodulated PDCCH candidates and calculating the mutual information based on the LLR magnitudes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a channel state feedback (CSF) report indicating a first modulation and coding scheme (MCS) associated with a first one or more frequency domain resources of a frequency domain resource allocation, and a second MCS associated with a second one or more frequency domain resources of the frequency domain resource allocation, the first one or more frequency domain resources being associated with a frequency dependent residual side band (FDRSB) impairment. The UE may receive an indication that the first MCS and that the second MCS is to be used. The UE may receive one or more signals using the first MCS to decode the first one or more frequency domain resources and using the second MCS to decode the second one or more frequency domain resources. Numerous other aspects are described.
