Abstract: A method of non-coherent wireless communication performed by a wireless communication device includes generating information bits for transmission to another wireless communication device. The method also includes identifying a configuration for a polar code encoder for encoding the information bits. The method further includes encoding a set of the information bits with a polar code encoding operation based on the configuration to generate a codeword, the configuration rendering the polar code encoding operation incapable of generating a codeword that is a bit-flipped counterpart of another codeword that the polar code encoding operation is capable of generating based on the configuration. The method still further includes transmitting the codeword via a wireless channel without a reference signal.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for allowing for the coexistence of legacy and non-legacy PUCCH formats. An example method generally includes generating a first orthogonal sequence for a first payload for a physical uplink control channel (PUCCH) to be transmitted; generating a second orthogonal sequence for a second payload for the PUCCH to be transmitted; mapping the first orthogonal sequence to a first set of virtual resources and the second orthogonal sequence to a second set of virtual resources; mapping the first set of virtual resources to a first set of physical resources and the second set of virtual resources to a second set of physical resources; and transmitting the first and second payloads for the PUCCH on the first and second sets of physical resources.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of spatially multiplexed synchronization signals in a same symbol period. The set of spatially multiplexed synchronization signals may indicate a parameter, such as a cell identifier, for the network entity. The network entity may select a sequence for each synchronization signal of the set. A user equipment (UE) may monitor for the set of spatially multiplexed synchronization signals during the same symbol period. The UE may differentiate each synchronization signal based on a respective sequence used to transmit each synchronization signal. The UE may determine that the set of spatially multiplexed synchronization signals were transmitted by the network entity using multiple antenna ports. The UE may determine the parameter for the network entity based on receiving the set of spatially multiplexed synchronization signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a communication on a physical downlink shared channel (PDSCH) was successfully decoded or was not successfully decoded. The UE may transmit channel state information (CSI) feedback that includes PDSCH decoding information via a first operation based at least in part on the determination that the communication was successfully decoded, or via a second operation based at least in part on the determination that the communication was not successfully decoded. Numerous other aspects are provided.

Abstract: In an example, a user equipment (UE) may receive, from a base station, a message indicating activation or reactivation of semi-persistent scheduling (SPS) between the UE and the base station. The UE may determine, based on the message, a first resource for transmitting a first acknowledgement/negative-acknowledgement (ACK/NACK) to acknowledge reception of the message. The UE may also receive, from the base station and subsequent to the receiving of the message, an SPS message. The UE may also determine a second resource for transmitting a second ACK/NACK to acknowledge reception of the SPS message. The UE may also transmit, to the base station, the first ACK/NACK on the first resource and the second ACK/NACK on the second resource.

Abstract: An acknowledgment (ACK)/negative-ACK (NACK)-based relaying scheme for uplink coverage improvement is provided. A relay station receives, from a destination device, a first feedback transmission associated with the first data transmission. The relay station determines whether the destination device successfully receives the first data transmission based on the first feedback transmission. The relay station communicates, with the destination device, a second feedback transmission associated with the first data transmission when the destination device does not successfully receive the first data transmission. The relay station communicates, with the destination device, a second data transmission associated with the second feedback transmission, in which the second data transmission comprises at least a portion of the first data transmission.

Abstract: Aspects described herein relate to receiving one or more downlink transmissions from a base station, and transmitting, based on comparing one or more parameter values of the one or more downlink transmissions to one or more threshold values, a sounding reference signal (SRS) to the base station over uplink resources. Other aspects relate to receiving, from a user equipment (UE), feedback related to decoding one or more downlink transmissions, wherein the feedback includes an indication that the UE is transmitting a SRS, and receiving, based on the indication, the SRS from the UE over uplink resources.

Abstract: Aspects relate to providing a status bit to a base station, where the status bit indicates whether all of multiple downlink transmissions have been successfully decoded. In an aspect, a user equipment (UE) receives a plurality of downlink transmissions from a base station, and generates a plurality of acknowledgement data respectively for the plurality of downlink transmissions, each of the plurality of acknowledgement data indicating whether a respective downlink transmission of the plurality of downlink transmissions has been successfully decoded. The UE further transmits, to the base station, at least one status bit based on the plurality of acknowledgement data, the at least one status bit indicating whether all of the plurality of downlink transmissions have been successfully decoded.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may multiplex a scheduling request (SR) associated with a first priority and a first physical uplink control channel (PUCCH) format with a hybrid automatic repeat request acknowledgement (HARQ-ACK) associated with a second priority and a second PUCCH format to form a multiplexed SR and HARQ-ACK. The UE may transmit, to a base station, the multiplexed SR and HARQ-ACK using a sequence in a PUCCH format 1 resource, wherein the sequence is based at least in part on whether the SR is a positive value or a negative value. Numerous other aspects are described.

Abstract: Wireless communication systems and methods related to interference prediction and reporting are provided. A user equipment (UE) obtains a sequence of interference measurements, where each interference measurement in the sequence is obtained at a different measurement time instant. The UE may determine, based on an interference predictor associated with the sequence of interference measurements, one or more predicted channel state information (CSI) values at one or more future time instants. The UE may transmit, to a base station (BS), a report including the one or more predicted CSI values.
