Abstract: Methods, systems, and devices for wireless communication are described. A device may receive a grant that schedules a set of sidelink occasions associated with sidelink communication from the device, and that indicates a set of uplink occasions for indicating feedback associated with the sidelink communication. The device may transmit a sidelink message during a sidelink occasion of the set of sidelink occasions, and generate feedback information based on the transmitted sidelink message. The feedback information may include an acknowledgement (ACK) or a negative acknowledgment (NACK) associated with the sidelink message. The device may transmit an uplink feedback message including the feedback information during an uplink occasion of the set of uplink occasions. The feedback information may include an indication of the ACK or the NACK.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may map hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback that includes a first HARQ-ACK bit associated with a high priority and a second HARQ-ACK bit associated with a low priority to a sequence cyclic shift value that provides an unequal reliability between the first HARQ-ACK bit and the second HARQ-ACK bit. The UE may transmit, to a base station, the HARQ-ACK feedback via a physical uplink control channel (PUCCH) format 0. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to adjust a random access message that is transmitted to a base station in an asynchronous uplink transmission. The UE may use a constrained mapping of time and frequency resources for the random access message or transmit all portions of the message in a continuous transmission. The UE may also adjust the timing of the portions of the message. The base station may use a portion of the message, such as a preamble, to perform channel estimation for another portion of the message, such as a payload, to improve decoding of the transmitted message. Additionally, the UE may configure a waveform of the message to improve the continuous transmission of the message, for example by reducing interference between portions of the message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access preamble to a base station as part of a two-step random access procedure. The UE may generate the preamble by identifying a discrete Fourier transform (DFT) matrix and generating a set of sequences based on the DFT matrix. Each sequence of the set of sequences may be generated by selecting a column of the DFT matrix and performing deterministic sampling of respective entries from the selected column in accordance with a sampling function. The UE may then select a sequence from the set of sequences based on generating the set of sequence. The UE may transmit the selected sequence to a wireless device (e.g., a base station).

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide a mechanism for managing a sequential order for performing a deferral procedure and at least one other slot index-dependent procedure in a wireless communication system. In particular aspects, a user equipment, UE, may be configured to perform a first slot index-dependent procedure and a deferral procedure of uplink repetitions. The UE may determine a sequential order for performing the deferral procedure and the first slot index-dependent procedure, and may then perform the deferral procedure and the first slot index-dependent procedure in the sequential order. The sequential order may include performing the deferral procedure before the first slot index-dependent procedure, performing the deferral procedure after the first slot index-dependent procedure, or a sequential order that is based on a type of procedure of the first slot index-dependent procedure.

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: Methods, systems, and devices for wireless communications are described. Techniques are described herein for managing timers for hybrid automatic repeat request (HARQ) processes associated with multiple configured grants that are active at the same time. Techniques are also described herein for allocating HARQ identifiers (IDs) to HARQ processes associated with multiple configured grants that are active at the same time. A user equipment (UE) may configure timers to be associated with a HARQ ID and a configured grant. A base station or UE may include indicators of the configured grants associated with a HARQ process when exchanging signaling about the HARQ process. A UE may allocate HARQ IDs to multiple configured grants to reduce a likelihood that HARQ processes collide.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may provide a feedback message to a base station that includes a feedback report that indicates successful or unsuccessful receipt of multiple downlink transmissions, and also includes an indication of a number of unsuccessful receipts that are due to unsuccessful receipt of data channel communications. The indication of the number of unsuccessful receipts of data channel transmissions may be provided as a binary representation of the total number, or may be provided as a quantized value in which each quantized point is associated with a certain number of unsuccessfully received data channel transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, a sidelink user equipment (UE) operating in a power saving mode may identify a resource reservation configuration for communicating within a resource pool allocated for sidelink communications. The UE may operate in a first power state of the power saving mode during a sensing window. The sensing window may correspond to a resource selection window of the resource pool. The UE may transition, after the sensing window, from the first power state to a second power state that may consume more power than the first power state. The UE may identify a subset of resources of the resource pool in the resource selection window that are available for sidelink transmission by the UE based on transitioning between the first power state and the second power state.
