Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect, a method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) that includes downlink control information (DCI). The DCI indicates a configuration of resources associated with RMSI repetition or RMSI slot aggregation. The method further includes monitoring for one or more RMSI messages based on the configuration of resources. The monitoring includes monitoring for multiple repetitions of an RMSI message based on the configuration of resources being associated with RMSI repetition and monitoring for a single RMSI message that is divided across multiple slots based on the configuration of resources being associated with RMSI slot aggregation. Other aspects are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include receiving, at a user equipment (UE) a random access channel (RACH) configuration message from a base station, where the message indicates a channel metric (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), or the like) and a threshold associated with the channel metric. The, UE may measure a reference signal (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), or the like) and select a RACH procedure based on comparing the measured channel metric to the threshold. For example, the UE may select a two-step RACH procedure if the measured channel metric satisfies the threshold specified in the configuration. In some cases, the UE may select a RACH procedure or a listen-before-talk (LBT) procedure based on a QoS parameter.

Abstract: Certain aspects of the present disclosure provide techniques for selecting and indicating a quasi colocation (QCL) source signal for sidelink (SL) communications. For example, a scheduling node may select from multiple candidates a signal for a first user equipment (UE) to use as a spatial QCL source for a receive (RX) or transmit (TX) beam to use for communicating with a second UE on a SL interface. The scheduling node may then signal the first UE an indication of the selection of the signal.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications. An example method generally includes calculating a first power headroom report (PHR) for a half duplex (HD) operating mode, calculating a second PHR for a full duplex (FD) operating mode during which maximum uplink transmit power is subject to one or more self-interference constraints, determining whether to report the first PHR, the second PHR, or both, and reporting at least one of the first PHR or the second PHR to a network entity, in accordance with the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a serving cell (e.g., serving base station), an indication to update a transmission configuration indicator (TCI) state of a first component carrier associated with a neighboring cell (e.g., neighboring base station). In some cases, the UE may be configured with a serving cell update rule and a neighboring cell update rule. The UE may determine, in accordance with a neighboring cell update rule, whether to update the TCI state across multiple component carriers (e.g., in a component carrier list) associated with the first component carrier based on the first component carrier being associated with the neighboring cell. The UE may update the TCI state of at least the first component carrier in accordance with the neighboring cell update rule.

Abstract: Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) sequence selection. One aspect provides a method for wireless communication by a first wireless node. The method generally includes selecting a type of DMRS sequence to be used for communication with a second wireless node based on a signal quality associated with the communication, receiving a message having the type of DMRS sequence, and performing channel estimation based on the DMRS sequence using the message.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may monitor for a transmission of a synchronization signal block that includes a first portion generated using a first waveform type and a second portion using a second waveform type that is different than the first waveform type. The wireless device may detect the first portion of the synchronization signal block based on the first waveform type used for the first portion. After detecting the first portion of the synchronization signal block, the wireless device may process the second portion of the synchronization signal block based on information obtained from the first portion of the synchronization signal block. The information obtained from the first portion of the synchronization signal block may include timing information, frequency information, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive an indication of a physical uplink control channel (PUCCH) resource for providing hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission from a second UE. The first UE may transmit the HARQ feedback for the sidelink data transmission on the PUCCH resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for detection of beam failure and beam failure recovery. A user equipment (UE) may perform measurements on one or more reference signals for one or more beams. In the event that one of the beams has a measurement that indicates a potential beam failure, the UE may increment a beam failure count (BFC) at a physical layer of the UE, and start a BFC timer. In the event that the BFC reaches a threshold value prior to expiration of the BFC timer, the UE may trigger a switch to a different active beam, provide a beam failure indication (BFI) to a higher layer of the UE, or both. A higher layer at the UE may autonomously adjust a BFI threshold for a number of BFIs that are needed to trigger a beam failure declaration to the base station.
