Abstract: Methods, systems, and devices for reporting redundancy version with feedback information. are described. A user equipment (UE) may transmit, to a base station, feedback information corresponding to a code block group in conjunction with an indication of a redundancy version for retransmission of the code block group. The UE may monitor for the retransmission of the code block group based on the indication of the redundancy version for the retransmission of the code block group. The UE may then decode the retransmission of the code block group based on the monitoring and the redundancy version for the retransmission of the code block group.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for phase noise (PN) mitigation on multiple component carriers (CCs). A method that may be performed by a user equipment (UE) includes estimating impairments (e.g., common phase error (CPE) and/or inter-carrier interference (ICI)) caused by PN for only a first CC configured for the UE, wherein the first CC is configured with pilots for PN mitigation and mitigating the PN on each CC for all CCs configured for the UE based, at least in part, on the estimated impairments for the first CC.

Abstract: Methods, systems, and devices for wireless communications are described. A non-coherent modulation configuration may be selected for a transmission of a set of data based on a radio frequency spectrum band used for the transmission. After selecting the non-coherent modulation configuration, the set of data may be modulated using a differential phase shift keying modulation technique. After selecting the non-coherent modulation configuration, a set of frequency-domain symbols may be generated from the set of modulated symbols using a discrete Fourier transform. The set of frequency-domain symbols may be mapped to a set of subcarriers, and a time-domain waveform may be generated from the mapped set of frequency-domain symbols, yielding a time-domain waveform. The time-domain waveform may be transmitted over the radio frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. An example method includes receiving a first transmission of one or more code blocks in a first slot and transmitting uplink control information that includes acknowledgement information for the one or more code blocks. The method also includes receiving a scheduling signal that indicates one or more parameters associated with a re-transmission scheduling policy based at least in part on the acknowledgement information. The method also includes receiving a second transmission of at least a portion of the one or more code blocks in a second slot and decoding the second transmission of at least the portion of the one or more code blocks according to the re-transmission scheduling policy.

Abstract: Aspects described herein relate receiving a signal having a waveform including, within a symbol, resource elements for a physical downlink shared channel (PDSCH) and separate resource elements for multiple pilots to enable phase tracking, estimating, based on the multiple pilots, a channel response of the PDSCH, and removing, from the signal, a phase noise computed based on the channel response estimated for the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration indicating a set of resources for a reference signal to track an in-phase and quadrature-phase imbalance of the UE. The set of resources may include a first subset of resources for transmitting the reference signal and a second subset of resources for a mirror image signal that is generated during upconversion of the reference signal. The UE may upconvert the reference signal to a set of subcarriers corresponding to the first subset of resources and transmit the upconverted reference signal on the first subset of resources. The base station may receive the reference signal and the mirror image signal and determine a signal adjustment for communications with the UE based on the received reference signal and the received mirror image signal.

Abstract: Example aspects include a method, apparatus, and computer-readable medium for scheduling transmissions of transport blocks (TBs) at a base station of a wireless communication network, comprising accessing static transmission information indicating configuration information of TB transmissions. The aspects further include transmitting, to a user equipment (UE), first downlink control information (DCI) corresponding to a first transmission. Additionally, the aspects include transmitting, to the UE according to the static transmission information and the first DCI, the first transmission comprising at least a portion of encoded bits of the TB. Additionally, the aspects include receiving, from the UE, an indication of at least one code block that failed to be successfully decoded. Additionally, the aspects include transmitting, to the UE, second DCI corresponding to a second transmission. Additionally, the aspects include retransmitting, to the UE according to the static transmission information, the first DCI, and the second DCI.

Abstract: Aspects of disclosure relate to a UE reporting to a gNB time delays and phases of pilot signals received via multiple transmission paths in order for the gNB to pre-equalize a future transmission to the UE. The UE determines a first time delay for receiving a first pilot signal from a gNB via a first path, determines a second time delay for receiving a second pilot signal from the gNB via a second path, and generates a report based on the first time delay and the second time delay. The UE then sends the report to the gNB and receives a multi-TRP signal from the gNB via the first path and the second path, wherein the multi-TRP signal is pre-equalized for transmission based on the report to at least have a same time delay as a shorter one of the first time delay or the second time delay.

Abstract: Wireless communication techniques for supporting, selecting, and using multiple waveforms and/or multiple decoders for downlink wireless communication are discussed. A UE may transmit to a base station a request to use a first waveform during a first time period for downlink wireless communication. The UE may receive from the base station a response to the request that includes an indication of a selected waveform to use during the first time period for the downlink wireless communication.
