Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a set of data resource elements for transmitting data in one or more symbols periods. The first wireless device may generate, for the one or more symbol periods based on the set of data resource elements, a sequence of a set of pilot resource elements associated with the set of data resource elements, the sequence of the set of pilot resource elements including a phase tracking reference signal. The first wireless device may transmit, to a second wireless device in the one or more symbol periods, the set of data resource elements and the set of pilot resource elements. The second wireless device may decode a first subset of the set of pilot resource elements based on a second subset of the set of pilot resource elements to determine the phase tracking reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message from a network entity indicating a first set of configuration parameters for tracking reference signals (TRSs) specific to the UE. The UE may monitor for one or more TRSs according to the first set of configuration parameters and during a first time interval. The UE may receive a layer-1 (L1) signal or a layer-2 (L2) signal from the network entity indicating a second set of configuration parameters for the TRSs specific to the UE that are different from the first set of configuration parameters. The UE may transmit an acknowledgement message to the network entity indicating the UE received the L1 signal or the L2 signal. During a second time interval subsequent to the first time interval, the UE may monitor for additional TRSs according to the second set of configuration parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may operate in a non-linear region of a power amplifier by reporting an indication of power amplifier characteristics and backoff values to a receiving device. The indication of the power amplifier characteristics and the backoff values may be based on power amplifier operation in the non-linear region of power amplifier characteristic curves. The transmitting device may transmit, to the receiving device, signaling using a single carrier waveform at a transmission power in the non-linear region of the power amplifier characteristic curves based on the indication. The receiving device may receive the signaling and use the power amplifier characteristics and the backoff values to perform debiasing and nonlinearity corrections to recover the original signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a demodulation reference signal (DMRS) configuration and a physical uplink shared channel (PUSCH) transmission mode for a user equipment to use for one or more uplink transmissions. The base station may transmit a dynamic joint indication of the DMRS configuration and the PUSCH transmission mode. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications employing multi-level coding with set partitioning on transmitting side and multi-level sequential decoding on the receiving side for latency minimization are described. In some systems, a transmitting device may transmit a code block group (CBG) to a receiving device including a first set of code blocks associated with a first decoding level and a second set of code blocks associated with a second decoding level. The receiving device may unsuccessfully decode one or more code blocks of the first set or the second set of code blocks and transmit a feedback message to the transmitting device. The transmitting device may determine that the data to be communicated via the CBG is latency-sensitive data and, as such, determine to retransmit both the first set and the second set of code blocks to the receiving device in response to receiving the feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. The following relates more specifically to hierarchical hybrid automatic repeat request (HARM) for multi-level coding with multi-level sequential demodulation and decoding and code block grouping per decoding level. A user equipment (UE) may receive, during a first time period, a transmission from a base station including a first and second code block group (CBG) with codeblocks associated with a first and second decoding level. The UE may fail to decode the first CBG, may not decode the second CBG, may store post processing samples for the second CBG, and may transmit a feedback message to the base station. The base station may retransmit the first CBG and new data on the second CBG in a second time period. The UE may decode the first CBG and use the post processing samples to decode the second CBG from the first time period.

Abstract: An apparatus for wireless communication includes a transmitter and a receiver. The receiver is configured to receive a first code block (CB) that is associated with a code block group (CBG) and that is included in a transport block (TB). The receiver is further configured to receive a second CB that is associated with the CBG and that is included in the TB. The first CB is distinct from the second CB. The second CB includes at least a first bit that is associated with the first CB.
