Abstract: Methods, systems, and devices for wireless communications are described. In polar coding, some bits channels have a higher reliability and other bit channels have a lower reliability. Data may be transmitted on some of the bit channels, and frozen values known to both the receiver and transmitter may be transmitted on the remaining bit channels. The performance of different polar code schemes (e.g., which bit channels are frozen) may depend on the decoder the receiving device uses. A receiving device (e.g., a user equipment for downlink transmissions) may indicate a decoder or polar decoding capability to the transmitting device (e.g., the network entity for downlink transmissions), and the transmitting device may select and indicate to the receiving device a polar coding scheme based on the indicated decoder or decoding capability. The transmitting device may transmit a communication to the receiving device encoded in accordance with the indicated polar coding scheme.

Abstract: In some aspects of the systems, methods, and devices described herein, one or more asymmetric modulation constellations may be utilized. For example, a modulation constellation utilized to modulate data symbols may be asymmetric. In some approaches, an asymmetric modulation constellation may be generated by introducing a phase shift (e.g., cyclic shift, phase rotation) to one or more constellation points of a modulation constellation. An asymmetric modulation constellation may allow detecting phase shifts without ambiguity. For example, a user equipment (UE) may perform channel estimation or phase noise estimation aided by data symbols that are modulated with an asymmetric modulation constellation. In some examples, a UE may receive a message from a network entity indicating a configuration of an asymmetric modulation constellation. The UE may demodulate data symbols of a data signal based on a channel characterization estimate that is associated with the configuration of the asymmetric modulation constellation.

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: 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: A transmitting device maps complex valued symbols in sequence to physical resource blocks for a sidelink transmission. The transmitting device reserves a first symbol of a subframe, where resource elements in the first symbol of the subframe are not considered in mapping the complex valued symbols to the physical resource blocks for the sidelink transmission. The transmitting device transmits the sidelink transmission after mapping the complex valued symbols to the physical resource blocks. A receiving device receives the sidelink transmission and decodes the sidelink transmission to determine complex valued symbols that are mapped in sequence to physical resource blocks of the sidelink transmission, where the complex valued symbols are not mapped to resource elements in a first symbol of a subframe.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment may receive, from a network entity, information indicating a resource allocation associated with a physical downlink shared channel (PDSCH) for a second user equipment and an indication to measure a demodulation reference signal (DMRS) associated with the PDSCH for the second user equipment. The second user equipment may be in spatial angular proximity to the first user equipment. The first user equipment may measure the DMRS associated with the second user equipment, and may transmit, to the network entity, a beam management report including measurements associated with the DMRS for the second user equipment. Based on the measurements associated with the DMRS for the second user equipment, the network entity may adjust a directional beam associated with the first user equipment.

Abstract: Certain aspects of the present disclosure provide techniques for channel aware demodulation reference signals (DMRS). An example method, performed at a user equipment (UE), generally includes receiving a message indicating one or more parameters for dynamic DMRS resource allocation, and communicating during one or more periods using DMRS resources dynamically allocated for the one or more periods based on the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may transmit a first report indicating a capability to support per codeword demodulation for a set of codewords, a second type of demodulation for the set of codewords, or both. The UE may receive, based on transmitting the first report, the set of codewords over a set of spatial streams in accordance with the per codeword demodulation or the second type of demodulation. The UE may transmit a second report indicating a capacity ratio metric for each codeword of the set of codewords based on receiving the set of codewords over the set of spatial streams in accordance with the per codeword demodulation or the second type of demodulation.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitter device may encode information for a message using a spinal code. The transmitter device may divide the information into sets of bits each including a variable quantity k of bits, and map the sets of bits to symbols to generate a message. The transmitter device may transmit the symbols in an order based on the k values (symbols with smaller k values at the beginning of the message and larger k values at the end). Based on receiving the message, a receiver device may identify the k of each symbol and decode the symbols. The receiver device may identify a partial codeword or determine a likelihood of error associated with the message, which the receiver device may indicate via a feedback message. The transmitter device may retransmit a portion of the message based on the feedback.
