Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include receiving, from a base station (BS), a resource pool (RP) configuration that indicates resources in a licensed frequency band reserved for sidelink control information (SCI), transmitting, to a second sidelink UE, the SCI in the reserved resources, wherein the SCI includes a starting position of channel occupancy time (COT) resources in an unlicensed frequency band, and transmitting, to the second sidelink UE, a physical sidelink shared channel (PSSCH) via the COT resources in the unlicensed frequency band.

Abstract: Symbol alignment and power scaling are provided for different length transmission time intervals (TTIs) within predefined boundaries, such as boundaries of a slot of a subframe. Described techniques provide for identifying time and/or frequency resources for one or more TTIs and allocating such resources based on a location within a subframe, pilot signals that may be transmitted using the resources, other processing timelines, or any combination thereof. In some cases, a power allocation for symbols within a TTI may be determined based on the allocated resources for the TTI. Frequency hopping patterns and power scaling for three-symbol TTIs are also provided.

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: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support backscatter-based positioning. In a first aspect, a method of wireless communication includes receiving multiple measurement reports associated with a tag device. The multiple measurement including, for each transmission/reception point (TRP) of multiple TRPs, a measurement report of the TRP. The method further includes determining, based on the multiple measurement reports, a position of the tag device having a tag delay that is unknown to a network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a semi-persistent scheduling (SPS) downlink communication. The UE may detect a collision between a configured uplink resource associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SPS downlink communication and a candidate synchronization signal block (SSB) position. The UE may transmit the HARQ-ACK for the SPS downlink communication in the configured uplink resource or in a deferred uplink resource in connection with detecting the collision. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may use a downlink control information (DCI) message to indicate timing resources to a user equipment (UE) for multiple downlink data repetitions in a slot. In a first implementation, the base station may indicate an explicit time domain resource allocation (TDRA) for one repetition in the TDRA field of the DCI, and the UE may determine implicit TDRAs for the other repetitions based on the explicit TDRA. In a second implementation, the base station may indicate a total TDRA for the full set of repetitions in the TDRA field, and the UE may divide the total TDRA into individual TDRAs for the repetitions. The UE may receive the downlink data repetitions based on determining the TDRAs and may transmit a feedback message in response based on a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook.

Abstract: A method of wireless communication includes performing, by a user equipment (UE) device, a channel sensing operation during a first window of a frame period associated with a wireless communication network. Performing the channel sensing operation includes performing a direction-based scan of one or more beams associated with the wireless communication network, and the channel sensing operation is included in a joint sensing operation performed with a base station. The method further includes, based at least in part on a result of the channel sensing operation, determining whether to perform, during a second window of the frame period, one or more communication operations with the base station.

Abstract: Disclosed are methods and systems for monitoring control channel candidates in a common search space (or a common search space set) in a wireless communication network. One of the methods is performed at a user equipment (UE). The method comprises: determining a first set of parameters for configuring a first set of monitoring occasions for the UE to monitor control channel candidates in a common search space (CSS); transmitting, to a network entity, an indication indicating the first set of parameters; and monitoring control channel candidates in the CSS during the first set of monitoring occasions.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a device (e.g., a user equipment (UE)) may obtain a configuration message indicating one or more neural network models from abase station. The UE may then obtain an indication of a sequence of operations for a signal processing procedure for a neural network model of the one or more neural network models. In some examples, the signal processing procedure includes an input pre-processing procedure or an output pre-processing procedure. Upon obtaining a signal from a base station, the UE may perform the signal processing procedure on the received signal for the neural network model according to the sequence of operations.
