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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability for the UE to support narrowband control signaling over a narrowband component carrier that is separate from data channel signaling over one or more wideband component carriers. The UE may receive control signaling indicating a configuration for the narrowband component carrier based on the capability and monitor for the narrowband control signaling on the narrowband component carrier based on the configuration. The UE may perform signal processing on narrowband signaling using a dedicated narrowband receive chain, which may include lower power components than a receive chain for wideband signaling.

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. A user equipment (UE) receives control signaling from the base station indicating a set of transmission mode indicators or transmission mode options and a set of demodulation reference signal (DMRS) configurations for every transmission mode from a set of transmission modes. The base station transmits additional control signaling to dynamically indicate a transmission mode or a combination of transmission mode indicators and DMRS configuration parameters to signal the transmission mode and one or more associated DMRS configurations. The UE identifies a DMRS configuration and a transmission mode based on the additional control signaling. The UE receives one or more DMRSs from multiple transmission reception points (TRPs) based on the joint/disjoint DMRS and transmission mode signaling. The UE receives one or more data messages from the TRPs based on the transmission mode indication and based on the received DMRSs.

Abstract: Certain aspects of the present disclosure provide techniques for network assisted selection of UE antenna ports for uplink transmissions. A method for wireless communication by a user equipment (UE) includes transmitting, to a network entity, a plurality of sounding reference signals over a plurality of UE antenna ports. The method further includes receiving, from the network entity, an indication of one or more antenna port indexes associated with one or more preferred antenna ports for uplink transmissions, and transmitting UE uplink transmissions to the network entity using one or more selected antenna ports of the one or more indicated preferred antenna ports.

Abstract: Methods, systems, and devices for wireless communications are described that support a single carrier multi-level coding (MLC) amplitude phase shift keying (APSK) modulated waveform. For example, a user equipment (UE) capable to communicate using MLC APSK modulated waveforms may transmit a channel state information (CSI) report, including a recommendation for a waveform configuration, to a base station. The base station may receive the CSI report and may transmit a configuration message to the UE, which may configure the UE with a set of waveform parameters associated with MLC APSK modulation. The UE may receive the configuration message and may communicate with the base station using MLC APSK modulated waveforms and based on the set of waveform parameters, which may reduce phase noise and provide lower peak average power ratio (PAPR) signaling.

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: Methods, systems, and devices for wireless communications are described. One method may include a user equipment (UE) receiving, in a first transmission time interval, a code block group including a set of code blocks associated with a set of codewords, each codeword being associated with one of a set of decoding levels introduced in communication scheme that uses multi-level coded modulation and multi-level sequential decoding. The UE may determine that a decoding procedure is unsuccessful, and transmit a feedback message including a first indicator that the decoding procedure was unsuccessful and a second indicator of a lowest decoding level for which the decoding procedure was unsuccessful. The UE may then receive, from the base station in a second transmission time interval, a retransmission of code blocks of the lowest failed decoding level coupled to a new data transmission for code blocks associated with all other decoding levels.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to perform receiver-side noise statistics (Rnn) estimation and for an extended reality (XR) device to perform log likelihood ratio (LLR) scaling estimation. For example, the UE may transmit a first set of reference signals to the XR device. The XR device may sample the reference signals and transmit an indication of quantized samples such that the UE may perform Rnn estimations and generate a pre-equalization matrix. The UE may transmit a set of pre-equalized reference signals to the XR device such that the XR device may estimate LLR scaling coefficients. In some examples, the UE may determine the pre-equalization matrix by performing a filtering of reference signal measurements. The UE may apply whitening to account for momentary interference, and may indicate a whitening matrix to the XR device.
