Abstract: Aspects described herein relate to adding a set of redundant subcarriers to a set of data subcarriers to be transmitted in a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform, interleaving, based on a permutation matrix, the set of redundant subcarriers with the set of data subcarriers to generate a permutation of subcarriers, mapping the permutation of subcarriers as input to an inverse fast Fourier transform (IFFT), and generating the UW-OFDM waveform based on output of the IFFT. Other aspects relate to receiving and processing the UW-OFDM waveform.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform, wherein the SSB has a uniform bandwidth allocation for each of a primary synchronization signal (PSS) included in the SSB, a secondary synchronization signal (SSS) included in the SSB, and physical broadcast channel (PBCH) data included in the SSB. The UE may perform initial channel access based at least in part on the SSB. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for frequency tracking and timing tracking using wideband reference signals (RSs). A method that may be performed by a user equipment (UE) includes monitoring for a wideband RS from a network entity when one or more conditions are met, the wideband RS occupying a wider band of frequency resources than a tracking reference signal (TRS) transmitted by the network entity; and performing at least one of frequency tracking or timing tracking based on the monitoring.

Abstract: Aspects of the disclosure relate to aperiodic transmission of one or more instances of at least one synchronization signal to a user equipment (UE). For example, the base station may allocate a plurality of time resources for aperiodic transmission of one or more instances of at least one synchronization signal different from a synchronization signal block transmitted by the base station. The base station may further transmit the aperiodic transmission of the one or more instances of the at least one synchronization signal to at least one UE using the plurality of time resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may reserve a first set of sidelink resources for a first transmission to a second UE. The UE may transmit a beam-based full duplex (FD) opportunity announcement associated with a second transmission that at least partially overlaps the first transmission in time, the beam-based FD opportunity announcement indicating a first transmission beam associated with the third UE. Numerous other aspects are described.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, a UE monitors for sidelink resource reservations in slots belonging to a sidelink resource pool during a sensing window including one or more slots in which the UE transmits, an inclusion of the one or more slots being based on a condition for sidelink FD communication, and transmits a sidelink transmission using a resource selected from a subset of candidate sidelink resources in the sidelink resource pool after monitoring for the sidelink resource reservations. The method improves the efficiency and performance of SL communication by enabling FD operation and facilitating better resource selection and channel prioritization.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, based at least in part on using a sidelink with a second UE, a first indication of a first availability state associated with a sidelink air interface resource and detected by the first UE. The first UE may receive, based at least in part on using the sidelink, a second indication of a second availability state associated with the sidelink air interface resource, the second availability state not generated by the first UE. The first UE may select a duplex communication configuration based at least in part on the first availability state and the second availability state. The first UE may communicate with the second UE using the sidelink air interface resource based at least in part on the duplex communication configuration. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a UE to transmit a PUCCH formed by a flexible concatenation of different types of blocks, such as one or more data sample blocks, one or more RS blocks, and/or one or more gap blocks within a PUCCH symbol. In one aspect, a UE receives, from a network entity, an indication to transmit one or more PUCCH symbols that are associated with a coherent PUCCH format, where each PUCCH symbol of the one or more PUCCH symbols associated with the coherent PUCCH format includes at least one RS sample block, at least one data sample block, or at least one gap sample block multiplexed in time-domain. The UE transmits, for the network entity, the one or more PUCCH symbols.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UW-OFDM waveform techniques. A UE may receive, from a base station, an indication of one or more parameters for the UW-OFDM waveform. The UE may subsequently receive, from the base station, a downlink transmission having the UW-OFDM waveform based on the one or more parameters. A location of redundant subcarriers for the UW-OFDM waveform may be based on at least one of frequency resources allocated for the UE or a combination of the frequency resources allocated to multiple UEs.
