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 user equipment (UE) may transmit, to a base station, a request for a data transmission that includes multiple subsets of data each associated with a different constellation granularity. In response to the request, the base station may encode the data transmission using multiple different constellation granularities and may transit the encoded data transmission to the UE. For example, the UE may receive the data transmission including a first subset of data that was encoded by the base station using a first constellation granularity and a second subset of data that was encoded by the base station using a second constellation granularity. The UE may then iteratively estimate phase-noises associated with respective subsets of data and perform phase-noise correction operations on the entire data transmission based on the estimated phase-noises.

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.

Abstract: A first wireless device may receive, from a second wireless device, a transmission associated with an MLC scheme. The MLC scheme may include a plurality of bits with at least one first bit corresponding to a first level of the plurality of bits and at least one second bit corresponding to a second level of the plurality of bits. The at least one first bit may be coded with a first level of complexity, but the at least one second bit may be coded with either the first level of complexity or a second level of complexity, where the first level of complexity may be a higher level of complexity than the second level of complexity. The first wireless device may decode the at least one first bit and the at least one second bit using a decoder having a corresponding level of complexity.

Abstract: Methods, systems, and devices for latency minimization in wireless communications employing multi-level coding and multi-level sequential demodulation and decoding are described. A user equipment (UE) receive a set of codeblock groups in a first time period. Each codeblock group jointly sharing same channel resources may be associated with a respective decoding level of a set of decoding levels. The UE may determine a first outcome for a first codeblock group and a second outcome for a second codeblock group. The UE may then transmit a feedback message that is based on the first outcome and the second outcome. In case that the feedback message indicates that the first outcome or the second outcome is a failed decoding procedure, the UE may receive, in a second time period, a retransmission of all the codeblock groups. These retransmissions may continue on additional time periods until all related codeblock groups are successfully decoded.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform pre-equalization for MIMO communications. A receiver device, such as an extended reality (XR) device, may be configured to offload a portion of data processing to a companion device, such as a user equipment (UE). In some aspects, the UE may generate a DFT-S-OFDM waveform and may apply a pre-equalization to the DFT-S-OFDM waveform. Applying the pre-equalization to the DFT-S-OFDM waveform may include applying a minimum mean square error (MMSE) pre-equalization to the DFT-S-OFDM waveform. The receiver device may receive the pre-equalized DFT-S-OFDM waveform from the UE and may process the pre-equalized DFT-S-OFDM waveform. For example, the receiver device may decode the pre-equalized DFT-S-OFDM waveform without performing fast Fourier transform (FFT) or inverse discrete Fourier transform (IDFT) operations.

In some aspects, a user equipment may transmit an indication of a capability of the UE to communicate one or more of uplink transmissions or downlink transmissions having amplitude-modulated phase tracking reference signals on at least a first layer of a multilayered communication link that includes the first layer and a second layer; and communicate an uplink transmission or a downlink transmission based at least in part on the indication. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, via a multi-layer communication link, an indication of one or more parameters for grouping code blocks (CBs) of a transport block (TB) into CB groups (CBGs). The receiving device may receive the TB having multiple CBs mapped to resources of the TB in a frequency first per layer (FFPL) mapping configuration, wherein the CBGs include a CB received on a first layer and a CB received on a second layer of the multi-layer communication link. The receiving device may transmit hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for the CBGs based at least in part on the grouping of the CBs. Numerous other aspects are described.

Abstract: In a wireless communication system, dynamic changes of a code block (CB) to resource element (RE) mapping type may improve decoding performance in some scenarios. Dynamic CB mapping may impact calculation of channel state information (CSI) metrics. A base station may transmit a physical downlink shared channel (PDSCH) based on a first dynamic CB mapping type in one or more slots. The base station may transmit a CSI reference signal (CSI-RS). A UE may receive the PDSCH and CSI-RS and calculate a channel quality indicator (CQI) and rank indicator (RI) based on the CRS assuming a second dynamic CB mapping type. The UE may transmit a CSI report including the CQI and the RI to the base station, which may assume the same second dynamic CB mapping type for the CQI and the RI.
