Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive an indication to use a first number of bits to report neural network based channel state information feedback (CSF). The first device may transmit, using a second number of bits that is different from the first number of bits, a report that indicates the CSF to a second device. Numerous other aspects are provided.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving multiple neural network training configurations for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes training each of a group of neural network decoder/encoder pairs in accordance with the received training configurations. A method of wireless communication, by a base station, includes transmitting multiple neural network training configurations to a user equipment (UE) for channel state feedback (CSF). Each configuration corresponds to a different neural network framework. The method also includes receiving a neural network decoder/encoder pair trained in accordance with the training configurations.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A source user equipment (UE) may transmit, to a relay UE, information identifying that the relay UE is one of a plurality of relay UEs selected for cooperative relaying of a communication from the source UE to a destination UE. A channel between the source UE and the relay UE may be one of a plurality of channels comprising a channel between the source UE and each relay UE of the plurality of relay UEs. The plurality of relay UEs may be selected based at least in part on a degree of correlation of the channel between the source UE and the relay UE with at least one other channel of the plurality of channels. The UE may transmit the communication to the plurality of relay UEs for cooperative relaying to the destination UE. Numerous other aspects are described.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: A base station may apply a nonlinear precoding to data for MU-MIMO transmission to a set of paired UEs to generate a first set of precoder symbols, and apply a linear precoding to the first set of precoder symbols to generate a second set of precoder symbols using a linear precoding matrix. The base station may normalize the second set of precoder symbols, and scale the second set of precoder symbols, before transmission of the data, using a scaling factor based on one or more of modulation symbols or a channel matrix. The base station may apply the linear precoding to DMRS associated with the data. The base station may transmit the second set of precoder symbols based on the second set of precoder symbols and the DMRS to the set of paired UEs.

Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.
