Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, via first frequency ranges and first time periods, a plurality of sidelink control blocks that each indicate a sidelink positioning reference signal burst pattern for one or more sidelink UEs. The UE may receive, within a second frequency range and during a second time period, a plurality of multiplexed sidelink positioning reference signals from the one or more sidelink UEs in accordance with the sidelink positioning reference signal burst patterns. The UE may determine a position of the UE based at least in part on the receiving of the plurality of multiplexed sidelink positioning reference signals.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit uplink (UL) messages in unlicensed spectrum with a reduced UL timing delay. The UL timing delay may be reduced by using a shortened transmission time interval (TTI) (e.g., a TTI that is reduced in duration relative to other TTIs in the system or in a legacy system) or by reducing the number of TTIs between a grant and the corresponding UL message. The reduced UL timing delay may decrease the likelihood that the UE will wait for a subsequent transmit opportunity (TxOp) to transmit the UL message. In some cases, the reduced UL timing delay corresponds to a reduced hybrid automatic repeat request (HARM) processing delay. In some cases, a time difference (e.g., measured in TTIs) between a measurement reference TTI a corresponding channel state information (CSI) report may also be reduced.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may schedule a user equipment (UE) for multiple transmission/reception point (TRP) communication. The network may transmit a single downlink control information (DCI) message to the UE to dynamically configure multiple transmission configuration indicator (TCI) states for the multiple TRPs. In a first example, the DCI message may include a bit field indicating a set of antenna ports and the multi-TRP scheme for transmission. In a second example, the DCI message may include a separate field indicating the multi-TRP scheme (e.g., based on UE capabilities). In a third example, the DCI may indicate redundancy versions (RVs) for different TRPs in an RV field or across multiple fields. In a fourth example, the DCI may include an indication of a precoding resource block group (PRG) size that may be interpreted differently based on the indicated multi-TRP scheme.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive sidelink control information from a second wireless device. The sidelink control information may include an allocation of a first set of resources for a sidelink transmission from the second wireless device to the first wireless device, along with an indication that schedules a second set of resources for additional sidelink transmissions between the first wireless device and the second wireless device that are scheduled to occur after the sidelink transmission from the second wireless device to the first wireless device. Based on the received indication, the first wireless device may communicate with the second wireless device via a sidelink shared channel using the first set of resources and the second set of resources.

Abstract: Aspects described herein relate to configuring communications over an acquired channel, where the configuration may indicate a set of resources used for communicating in at least one direction over the acquired channel. The set of resources may be based on a set of possible starting points within a slot for transmitting the communications.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a downlink transmission of a set of configurable downlink transmissions. The downlink transmission may include reference slots corresponding to offset values associated with one or more feedback occasions. The UE may construct a feedback codebook based on a first quantity of slots in the set of configurable downlink transmissions, a second quantity of reference slots in the set of configurable downlink transmissions, and a third quantity of configurable offset values associated with one or more feedback occasions. Based on a size of the feedback codebook, the UE may generate feedback bits for reporting whether the UE successfully received a downlink transmission in corresponding slots. In some examples, the UE may identify a slot with a symbol reserved for an uplink transmission, and skip generating a corresponding feedback bit for the identified slot.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support cross-slot scheduling of sidelink transmissions in a wireless communication system. A transmitting user equipment (UE) in communication with a receiving UE over a sidelink transmits cross-slot schedule information to the receiving UE at a time prior to a first slot over which a physical sidelink shared channel (PSSCH) transmission is to be transmitted to the receiving UE. The cross-slot schedule information includes information that is sufficient to decode the PSSCH transmission received by the receiving UE at the first slot, without requiring the receiving UE to decode a physical sidelink control channel (PSCCH) transmission including a sidelink control information (SCI) message received during the first slot. In aspects, the PSSCH transmission may be decoded in parallel with the PSCCH transmission received in the first slot.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication that includes one or more codepoints indicating a plurality of transmit precoder matrix indicator (TPMI) indices and/or a sounding reference signal (SRS) resource indicator (SRI) codepoint indicating one or more SRS resources. The UE may identify, based at least in part on the one or more codepoints, one or more TPMI indices, of the plurality of TPMI indices, for one or more repetitions of a codebook-based PUSCH transmission and/or may identify, based at least in part on the SRI codepoint, one or more SRS resources for the one or more repetitions. Numerous other aspects are provided.

Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.
