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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit a request, for an uplink transmission or a downlink transmission, for tone reservation on one or more subchannels allocated for phase tracking reference signals (PT-RSs); and transmit the uplink transmission or receiving the downlink transmission based at least in part on the request. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support blind common phase error (CPE) and residual carrier frequency offset mitigation. Generally, the described techniques provide for blind CPE mitigation at a receiving device without a phase tracking reference signal (PTRS) associated with less overhead and improved performance as compared to use of a PTRS to mitigate CPE. A receiving device may receive a shared channel message in a scheduled shared channel allocation in accordance with a PTRS configuration that omits a PTRS allocation based on a capability of the receiving device to apply blind CPE mitigation for shared channel receptions. In some examples, with a single DMRS symbol allocation, blind CPE mitigation for each subsequent data symbol of a shared channel message may be based on the blind CPE estimation for the previous symbol, which may enable robust mitigation of a residual carrier frequency offset.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining a constellation configuration for an amplitude phase shift keying (APSK) modulation scheme. The constellation configuration may be based on communication impairment information that is indicative of at least one communication impairment expected to impair a single-carrier waveform communication. Examples of communication impairments may include additive white gaussian noise (AWGN), phase noise, non-linear distortion, or any combination thereof, among other examples. Examples of a constellation configuration may include a quantity of rings in a constellation pattern associated with the APSK modulation scheme, a quantity of constellation points associated the rings, a ring radius associated with one or more rings, a phase offset to one or more rings, and a mapping of data bits to one or more constellation points, among other examples.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support synchronization signal block (SSB) coverage extension for a sub-terahertz (sub-THz) band. The UE may monitor for multiple primary synchronization signals (PSSs) in a first instance of an SSB, a number of PSSs determined by the base station based on a periodicity of the SSB. The UE may combine the PSSs and determine a frequency offset for the SSB. The UE may monitor for additional instances of the SSB in accordance with the frequency offset. In some examples, the UE may monitor for one or more secondary synchronization signals (SSSs) in the first and additional instances of the SSB and combine the SSSs. In addition, the UE may monitor for a physical broadcast channel (PBCH) in the first and additional instances of the SSB, and decode the PBCH using log-likelihood ratio (LLR) combining.

Abstract: Methods, systems, and devices for wireless communications are described. A base station communicates with a UE via transmission reception points (TRPs). A UE receives, from a base station, control signaling identifying a set of demodulation reference signal (DMRS) configurations. The UE receives, from the base station, control signaling activating a first DMRS configuration and a second DMRS configuration. The UE receives an indication for the UE to use a first transmission mode of a set of transmission modes to communicate with multiple TRPs of the base station. The UE selects at least one of the first DMRS configuration or the second DMRS configuration based on the indicated first transmission mode and a pre-defined logical association. The UE then receives DMRS signals from the TRPs of the base station, according to the selected at least one of the first DMRS configuration or the second DMRS configuration.

Abstract: A phase tracking reference signal (PTRS) may be enhanced to carry data encoded with a relative low modulation and coding scheme (MCS). A receive device may receiving a data channel, the data channel including a transport block encoded using a first MCS. The receiving device may receiving a PTRS interleaved with the data channel. The PTRS is encoded with the second MCS that is lower than the first MCS. The receiving device may decode the PTRS to determine PTRS data. The receiving device may track phase noise using the PTRS data as a transmitted sequence of the PTRS. The receiving device may decode the transport block for the data channel based on the first MCS and the tracked phase noise.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit signaling that configures a wireless device to use a multi-level coding (MLC) procedure to communicate with a base station. Based on receiving the signaling, the wireless device may select a channel quality indicator (CQI) index from a set of CQI indices that are associated with an MLC procedure. In some examples, the wireless device selects the CQI index from a set of CQI indices that includes both bit-interleaved coded modulation (BICM)-based and MLC-based CQI indices. In other examples, the wireless device selects the CQI index from a set of CQI indices that includes solely MLC-based CQI indices. The wireless device may transmit the selected CQI index to the base station. And the base station may select a modulation and coding scheme for subsequent transmissions to the wireless device based on the received CQI index.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for flexible selection of a type of mapping to use for mapping code blocks to a set of resources for transmission. A user equipment (UE) may transmit assistance information to a base station to assist the base station in selecting from a set of mapping types available for code block mapping. The UE may then receive, from the base station, an indication of a selected mapping type for code block mapping based on the assistance information. The assistance information may include a recommendation of a mapping type or a metric of a channel that the base station may use to select the mapping type. Because the mapping type may be selected dynamically (e.g., “on the fly”), the UE and the base station may be able to adaptively exploit different types of diversity.

Abstract: Aspects are provided which allow for a base station to transmit code blocks according to a frequency first per layer (FFPL) mapping, and for a UE to decode received code blocks according to the FFPL mapping. The base station maps a plurality of code blocks to multiple layers, where each of the code blocks is mapped to a plurality of resource elements initially by frequency and subsequently by time on only a single layer of the multiple layers. The base station then transmits data including the code blocks to a UE. Afterwards, the UE receives the data including the mapped code blocks in multiple layers from the base station, and the UE decodes the code blocks based on the mapping. Thus, improvements in link efficiency, reliability, and reduced power consumption compared to frequency first (FF) mapping approaches may be achieved.
