Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may construct, for adjusted fractally enhanced kernel (FRANK) polar coding, encoding code for encoding data of an ultra-reliable low latency (URLLC) communication, wherein an information bit assignment to an information bit set associated with the encoding code is performed based at least in part on an adjusted dimensionality factor, wherein the encoding code is all-stage FRANK polar code or partial-stage FRANK polar code, and wherein the encoding code is constructed for code block shortening or code block puncturing. In some aspects, the user equipment may transmit the URLLC communication encoded using the encoding code based at least in part on the information bit assignment to the information bit set. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: Wireless communication devices, systems, and methods related to communicating UCI are provided. For example, a method of wireless communication may include receiving, by a user equipment (UE) from a base station (BS), scheduling information for transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) and uplink control information (UCI) during a time period. The UCI may include channel state information (CSI) or a scheduling request (SR). The method may include determining, by the UE, that the UCI and a HARQ-ACK codebook have a common priority, the HARQ-ACK being based on the HARQ-ACK codebook. The method may include transmitting, by the UE to the BS, the HARQ-ACK and the UCI during the time period based on the scheduling information, the transmitted UCI using resources determined based on a duration associated with the HARQ-ACK codebook, and the duration being based on the UCI and the HARQ-ACK codebook having the common priority.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

Abstract: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may receive from a base station (BS), a subband precoding configuration indicating a plurality of precoders for a plurality of subbands based on a transmit power parameter, where each precoder of the plurality of precoders is configured for one subband of the plurality of subbands. Additionally, the UE may transmit to the BS, a communication signal in the plurality of subbands using the plurality of precoders, where the transmitted communication signal satisfies the transmit power parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a physical uplink control channel (PUCCH) transmission is associated with a first type of service or a second type of service, wherein the second type of service is associated with a higher reliability or a lower latency than the first type of service. The UE may transmit the PUCCH transmission using a first set of resources when the PUCCH transmission is associated with the first type of service or using a second set of resources when the PUCCH transmission is associated with the second type of service. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to perform power-boosting to increase power for specific portions (e.g., repetitions, symbols, slots) of an uplink transmission, where the portion may overlap with a previously-scheduled uplink transmission from another UE. The base station may configure the UE to apply power-boosting to all portions of the uplink transmission or over specific slots or repetitions of the uplink transmission, or to apply power-boosting if the uplink transmission occupies one slot or repetition. The base station may configure the UE semi-statically or dynamically with the power-boosting configuration, and may configure the UE to perform power-boosting for repetitions of the uplink transmission corresponding to one or more predefined transmission reception points, panels, beams, or precoders. The UE may transmit the uplink transmission to the base station based on the power-boosting configuration.
