Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a first wireless device may receive one or more sidelink control information messages scheduling a first multi-bit feedback and indicating a number of priority field values associated with respective feedback bits of the first multi-bit feedback. In such cases, the priority of the first multi-bit feedback may correspond to the highest priority field value. The first wireless device may determine that a first set of resources allocated for the first multi-bit feedback at least partially overlaps with a second set of resources allocated for a second feedback having a second priority, and the first wireless device may select the first or second feedback to transmit or receive based on the determined priorities of the first multi-bit feedback or the second feedback.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with periodic uplink grants that provide a number of repetitions and a redundancy version (RV) sequence for the repetitions. Prior to the start of an uplink grant period, the UE may determine a set of slots that are available for uplink transmissions in the uplink grant period. Based on the set of slots, the UE may determine a corresponding RV for repetitions of the uplink communication associated with each slot. The slots with uplink transmissions within the uplink grant period may be non-contiguous. Repetitions of an uplink communication may be configured to be transmitted across multiple uplink grant periods, which may be triggered based on a threshold value associated with the repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control transmission and multiple downlink data transmissions to a user equipment (UE). The UE may schedule an uplink data transmission based on the downlink control transmission and may schedule transmission acknowledgement messages based on the multiple downlink data transmissions. The UE may identify that the scheduled uplink data transmission overlaps with the scheduled transmission acknowledgement messages. The UE may generate one or more acknowledgement codebooks for transmission of the multiple transmission acknowledgment messages and may multiplex the one or more acknowledgement codebooks with the uplink data transmission on the uplink data channel. In some cases, the UE may multiplex the codebooks based on determining that a set of timing thresholds are satisfied by an earliest of the multiple transmission acknowledgement messages and the uplink data transmission with respect to one or more downlink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may determine resource amounts for transmitting feedback codebook for two different service types based on satisfaction of a multiplexing condition by overlapping resource schedules. The codebooks may be encoded according to different coding rates to generate encoded feedback codebooks. The encoded codebooks may be mapped to transmission resources according to codebook payload sizes, encoding rates, and available resources and transmitted according to the mapping.

Abstract: Certain aspects of the present disclosure provide techniques for configuring data transmission. Aspects relate to determining a data transmission configuration utilizing a machine-learning based algorithm, such as a data transmission configuration for ultra-reliable low-latency communication (URLLC) applications. A method that may be performed by a base station (BS) includes receiving a feedback report from a user equipment (UE) including an indication of a first state corresponding to a plurality of channel condition parameters and determining one or more actions based, at least in part, on the first state. The BS may determining the one or more actions utilizing a machine learning algorithm that uses a second state, where the second state is based, at least in part, on the first state.

Abstract: Techniques for peak-to-average power ratio (PAPR) reduction are described. Wireless devices may use one or more PAPR shaping resources, such as expanded bandwidth and/or pulse-shaping filtering, for shaping a signal to reduce PAPR. For example, expanded bandwidth may be utilized for adding a cyclic affix (CA), such as may comprise a cyclic prefix (CP), cyclic suffix (CS), etc., and combinations thereof, to a frequency domain data signal to provide a CP augmented frequency domain data signal used to generate a reduced PAPR time domain data signal. Additionally or alternatively, pulse-shaping filtering may be applied to a frequency domain signal to provide a pulse-shaped frequency domain data signal used to generate a reduced PAPR time domain data signal. Other aspects and features are also claimed and described.

Abstract: Aspects of the present disclosure include methods and devices for informing a base station of autonomously selected SL resources to allow the base station to adjust the DL transmission to mitigate the degradation of the reception of a DL transmission due to self-interference that overlaps with a SL transmission. A device may be configured to select resources for a SL transmission and to transmit, in an UL transmission to a base station, an indication of the resources selected for the SL transmission. A base station may be configured to receive, in an UL transmission, an indication of resources selected for a SL transmission from a UE, and to transmit, based on the indication of the resources selected for the SL transmission, at least one DL transmission that overlaps in time with the SL transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.

A user equipment (UE) may receive an indication of a set of frequency domain resources allocated to the UE for communicating data over a wireless channel. The UE may receive an indication of a waveform type associated with the set of frequency domain resources. The waveform type may be based at least in part on a data type of the data, may be used for a defined amount of time, and may be one of a plurality of waveform types that are multiplexed together over different frequency domain resources within a total system bandwidth. The UE may communicate within the set of frequency domain resources according to the indicated waveform type and the data type.
