Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE implements the technique to transmit to a network entity a report that includes an indication of a desired demodulator or precoding per precoding resource block group (PRG) for a group of one or more PRGs. The UE then demodulates downlink (DL) transmissions, transmitted from the network entity on the group of one or more PRGs, in accordance with the indication included in the report.

Abstract: Aspects of the disclosure relate to reporting and correcting a spatial misalignment of an orbital angular momentum (OAM) waveform communicated from a second device to a first device. In an aspect, the first device receives from the second device, the OAM waveform having a spatial misalignment with respect to the second device. The first device determines the spatial misalignment and further determines spatial coordinates for correcting the spatial misalignment and/or one or more channel measurements of the OAM waveform. Thereafter, the first device sends a report based on the spatial misalignment to the second device, the report including the spatial coordinates for correcting the spatial misalignment and/or the one or more channel measurements. The first device then receives an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is received having a corrected spatial alignment with respect to the second device based on the report.

Abstract: The base station may transmit to the UE, a first part and a second part of a PDSCH. The UE may decode the second part of the PDSCH. The first part of the PDSCH may be associated with a higher MCS than the second part of the PDSCH. The UE may estimate at least one of an ICI or a CPE associated with the PDSCH based on the decoding of the second part of the PDSCH. The UE may decode the first part of the PDSCH based on the decoding of the second part of the PDSCH. Decoding the first part of the PDSCH based on the decoding of the second part of the PDSCH may include correcting for the at least one of the ICI or the CPE associated with the PDSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may transmit, to a receiver device, an initial message associated with a communication using a first code rate. The transmitter device may receive, from the receiver device, first feedback information indicating that the communication was not successfully decoded by the receiver device. The transmitter device may transmit, to the receiver device based at least in part on the reception of the first feedback information, one or more retransmissions associated with the communication including a first retransmission, wherein the first retransmission includes a first number of bits to lower an effective code rate of the communication to a second code rate. The transmitter device may receive, from the receiver device, second feedback information indicating that the communication was successfully decoded by the receiver device. Numerous other aspects are described.

Abstract: A method of wireless communication by a user equipment (UE) includes reporting, to a base station, a requested downlink code block mapping, which has a defined duration. The method also includes receiving a first code block from the base station during the defined period of time. The method further includes receiving a second code block from the base station during the period of time. The method further includes decoding the first code block with a first demodulator according to the code block mapping. The method still further includes decoding the second code block with a second demodulator, which is different from the first demodulator, according to the code block mapping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a transmitter, a reference signal block provided based at least in part on an orthogonal frequency division multiplexing (OFDM) waveform. The UE may perform an estimation operation based at least in part on the reference signal block. The UE may receive a data transmission via a single carrier waveform based at least in part on the estimation operation. Numerous other aspects are provided.

Abstract: A base station may receive from a user equipment (UE) a proactive notification that the UE will perform a beam switch from a first UE beam to a second UE beam. In response, the base station may determine a beam switch slot on which the UE will perform the synchronized beam switch, and perform a link transient mitigation operation for communications with the UE after UE beam switch and until updating channel state information associated with a new UE beam. The base station may then receive from the UE channel state information feedback for a channel associated with the second UE beam, and adjust downlink data transmission parameters to be aligned with the second UE beam based on the received channel state information feedback (CSF). The base station may also adjust uplink data transmission parameters based on a sounding reference signal transmitted by the UE over the second UE beam.

Abstract: Aspects relate to analog-to-digital conversion of an analog signal. The resolution (number of bits) and/or the quantization levels of the analog-to-digital conversion may be configurable. A device may configure its analog-to-digital conversion parameters. For example, a first device may reduce the number of bits for its analog-to-digital converter to reduce power consumption. In this case, the first device may transmit an indication of selected analog-to-digital conversion parameters to a second device that will transmit to the first device. In this way, the second device may take appropriate action, if needed. A device may request another device to use certain analog-to-digital conversion parameters. For example, a first device may determine that a second device should use a larger number of bits for its analog-to-digital conversion process to improve the quality of the communication between the first and second devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a phase tracking reference signal. The phase tracking reference signal is transmitted using a single carrier waveform and encoded within a time domain. Accordingly, the UE may decode, from the base station, a message, based at least in part on the phase tracking reference signal. Numerous other aspects are provided.
