Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify conditions associated with one or more physical channels, for example, a set of resources with which the UE may be configured to communicate with a base station. The UE may determine whether to enable a reduced power mode based on the conditions satisfying certain criteria, for example, the set of resources corresponding allocated for particular transmissions. The UE may identify that the conditions satisfy corresponding criteria, and the UE may determine to enable the reduced power mode. The UE may accordingly modify operations one or more components of a receive chain of the UE. The UE may determine to disable the reduced power mode based on the conditions failing to satisfy the criteria, and the UE may modify operations of the one or more components of the receive chain accordingly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a wireless communication signal. The wireless communication device may process the wireless communication signal using a digital post distortion receiver based at least in part on performing a multi-level coding (MLC) set partitioning operation, wherein performing the MLC set partitioning operation comprises partitioning a quadrature amplitude modulation constellation set by bounding a maximum Euclidean distance of an error associated with decoding one or more least significant bits. Numerous other aspects are provided.

Abstract: In one aspect, performing, by a wireless communication device, a non-coherent encoding operation on first data to generate a first transmission, wherein the non-coherent encoding operation encodes data independent of channel state information (CSI); and transmitting, by the wireless communication device, the first transmission, wherein the first transmission is non-coherently encoded. In another aspect, receiving, by a wireless communication device, a first transmission, wherein the first transmission is non-coherently encoded independent of channel state information (CSI); and performing, by the wireless communication device, a non-coherent decoding operation on the first transmission to decode the first transmission. Other aspects and features are also claimed and described.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

Abstract: Systems and methods to detect spurious responses (spurs) in association with mmWave wireless communications are described. Such spurs may originate internal to the receiver (internal spurs) or external to the receiver (external spurs) originated in the transmitter. Embodiments operate to identify received mmWave wireless communication signal spurs in symbols, or portions thereof, which do not have transmissions directed to the receiving device. mmWave spur detection implementations of embodiments can detect spurs in real-time operation of the receiving device. Such real-time spur detection facilitates operation by the receiving device to perform spur removal in real-time operation of the receiving device, thus enabling removal of both internal spurs and external spurs as well as dynamically adapting to different scenarios that cause different spurs. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a supported channel latency indication that indicates a supported channel latency for time domain equalization by the UE. The UE may receive, from the network node, a downlink communication based at least in part on the supported channel latency indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit neural network (NN) capability information to a network entity. The network entity may train the NN model by selecting a NN-based precoder and generating associated coefficients. The network entity may transmit an indication of the precoder coefficients to the UE. The network entity may transmit demodulation reference signals (DMRSs) that have not been precoded and a physical downlink shared channel (PDSCH) signal that has been narrowband-precoded according to the indicated precoder. The UE may then perform and input a channel estimation to the NN model. The NN model may output the narrowband precoder, which the UE may use to generate a narrowband channel estimate and demodulate the narrowband precoded PDSCH signal. In some examples, the network entity may update NN coefficients and may indicate the updated NN coefficients to the UE.

Abstract: Aspects described herein relate to processing synchronization signal block (SSB) signals and/or corresponding system information block (SIB) based on whether the SSB is received directly from a network node or from a router in a path from the network node. For example, a signal originated from a network node can be received. It can be determined whether the SSB is received from the network node or from a router in a path from the network node, and the SSB or a corresponding system information block (SIB) of the network node can be processed based on whether the SSB is received from the network node or the router. Other aspects relate to indicating whether a SSB is from a network node or a router in the path.
