Abstract: Aspects of the disclosure relate to wireless communication utilizing a modulation and coding scheme that selectively or dynamically applies probabilistically-shaped coding (PCS) to modulate a transmitted waveform. A communication device may determine whether to apply PCS. If PCS is to be applied, the device can encode the message based on a systematic code; and if PCS is not to be applied, the device can encode the message based on a non-systematic code. Other aspects, embodiments, and features are also claimed and described

Abstract: Aspects of the disclosure relate to wireless communication with a waveform configured according to probabilistic constellation shaping in connection with modulation. A wireless transmission device may determine a sequence of amplitude symbols from a sequence of information bits using a distribution matcher (DM) configured for probabilistic amplitude shaping. The device may further apply error correction coding to encode an information block corresponding to at least a portion of the sequence of amplitude symbols. And the device may generate a sequence of output symbols for transmission based on the encoded information block. In various examples, the device may apply interleaving to one or more of the sequence of amplitude symbols, the information block, the encoded information block, or a combination of the sequence of amplitude symbols and the encoded information block, for the generating of the sequence of output symbols. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first number of antenna ports for which the UE may report channel state information (CSI), and a second indication of a second number of antenna ports on which the UE may measure CSI reference signals (CSI-RSs). The second number may be less than the first number. The UE may receive a third indication of one or more neural networks to be used by the UE for determination of the CSI associated with the first number. The UE may determine the CSI using the one or more neural networks and using measurements made by the UE on the second number as inputs to the one or more neural networks. The UE may transmit a report including the CSI associated with the first number determined via the one or more neural networks.

Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) configured to receive a downlink in a network configured for full duplex communication. The UE receives from the network an indication of a maximum rank of an uplink from an interfering, aggressor UE. The UE measures interference of a signal from the aggressor UE, and based on the measurement, determines one or more rank values for the aggressor UE, less than or equal to the maximum rank. The UE may further determine one or more channel parameters for downlink transmissions the UE receives, corresponding to the determined rank values. The UE then transmits a channel state information (CSI) report that includes an indication of at least one of the one or more rank values for the aggressor UE. The CSI report may further include the determined channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices (e.g., base stations, user equipment (UEs), etc.) may utilize polar coding along with hybrid automatic repeat request (HARQ) techniques. In these systems, a device may encode bits for transmission by mapping information and parity check bits to a first set of polarized bit channels of a polar code. If this transmission is not successfully received at a decoding device, the encoding device may generate a HARQ retransmission. The device may copy information bits to a second set of polarized bit channels of a second polar code containing the first polar code and may assign parity check bits to the second set of bit channels for the copied information bits. These additional parity check bits for the repeated information bits may increase transmission reliability and may support improved early termination at the decoding device.

Abstract: Certain aspects of the present disclosure provide techniques for collision handling for channel state information (CSI) reporting on a physical uplink shared channel (PUSCH). A method for wireless communications by a user equipment (UE) is provided. The method generally includes receiving scheduling for at least one CSI reporting transmission and at least one uplink transmission in a same slot. The UE determines to multiplex the at least one CSI and the at least one uplink transmission in the slot or to drop the at least one CSI or the at least one uplink transmission in the slot. The UE transmits in the slot at least one of: the at least one CSI transmission or the at least one uplink transmission based on the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may allocate data associated with a user equipment (UE), of two or more UEs, into at least one of a first part, a second part, or a combination thereof; multiplex the first part of the data associated with the UE with a first part of data associated with one or more other UEs, of the two or more UEs, to form multiplexed data; map the multiplexed data to a first set of layers; and map the second part of the data associated with the UE and a second part of the data associated with the one or more other UEs to a second set of layers.

Abstract: The described techniques provide for the use of sub-band-specific reference signal precoding. A user equipment (UE) may apply multiple precoding matrices to a reference signal to generate a set of precoded reference signals and may transmit the precoded reference signals over respective sub-bands within a given reference signal resource set. In some cases, the UE may transmit a different set of precoded reference signals in each of multiple reference signal resource sets. Upon receiving the precoded reference signals, a base station may perform wideband channel estimation for each sub-band in the given reference signal resource set. The base station may compute an average spectral efficiency for each reference signal resource set and may transmit a report to the UE. The report may include one or more communication parameters for future communications between the UE and base station.
