Abstract: Wireless communications systems and methods related to discontinuous reception (DRX) extended-on operations and dynamic transmission patterns in sidelink are provided. A first user equipment (UE) determines a transmission pattern for a first sidelink based on an extended DRX on-duration associated with a second sidelink different from the first sidelink, wherein the first sidelink is between the first UE and a second UE, and wherein the second sidelink is between the second UE and a third UE. The first UE transmits, to the second UE over the first sidelink during the extended DRX on-duration based on the transmission pattern, a communication signal.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may support beam measurements triggered by a wake-up signal (WUS) and that triggers an active duration of a receiving user equipment (UE). The WUS may trigger the receiving UE to perform a beam sweeping procedure during a beam measurement occasion that immediately preceding the active duration, or the UE may perform the beam sweeping procedure in the WUS resource itself. A UE may perform beam measurement procedures during active durations of a discontinuous reception (DRX) cycle, or outside of active durations of the DRX cycle. A receiving UE may be configured with a timing for performing a beam measurement procedure based on one or more offset values. The timing offset values may indicate a timing during active durations or prior to active durations.

Abstract: This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.

Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

Abstract: Wireless communications systems and methods related to indicating antenna configuration information and neural network information are disclosed. Neural network information may be selected for an encoder side based on an antenna configuration of a first device housing the encoder. This information may be transmitted with the antenna configuration information to a second device, which may jointly train the neural network with the first device. The first device may further transmit one or more weights after the training, which are stored with the antenna configuration information at the second device as well. When a third device with similar antenna configuration as the first device establishes communication with the second device, the second device may transmit neural network information, as well as weights, to the third device. The third device may use this information, instead of default information, to speed up neural network initialization and training.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from a transmitter, a sidelink communication and sidelink control information (SCI), associated with the sidelink communication, that indicates one or more distance parameter and angle parameter combinations for hybrid automatic repeat request (HARQ) feedback. The receiver may determine that the receiver satisfies a distance parameter and angle parameter combination of the one or more distance parameter and angle parameter combinations. The receiver may transmit, based at least in part on determining that the receiver satisfies the distance parameter and angle parameter combination, HARQ feedback for the sidelink communication to the transmitter on a sidelink. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location is represented as a hierarchy of two or more levels of description, wherein a highest level of description is relative to a fixed reference point, receives, from each of at least a subset of the plurality of transmission points, at least one positioning reference signal, and estimates the location of the UE based on characteristics of reception of the at least one positioning reference signal from each of the subset of the plurality of transmission points and the two or more levels of description and the fixed reference point for each of the subset of the plurality of transmission points.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position determination entity (PDE) receives a request to schedule an on-demand PRS positioning session of a UE at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is received. PDE determines the availability of the one or more parameters at the future time. PDE determines a PRS configuration for the scheduled on-demand PRS positioning session in advance of the future time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a user equipment (UE), a message that indicates whether the UE received a downlink transmission from the base station in a first frequency range. The base station may schedule one or more reference signal (RS) transmissions in the first frequency range and one or more RS transmissions in a second frequency range based at least in part on the message received from the UE, and reschedule the downlink transmission on a component carrier in either the first frequency range or the second frequency range based at least in part on channel quality information that is determined from the one or more RS transmissions in the first frequency range and the one or more RS transmissions in the second frequency range. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., new radio (NR) wireless communications systems), a base station may serve a large number of user equipment (UEs). The base station may allocate uplink control channel resources to the UEs. A UE may receive, from the base station, a first resource assignment for a first set of symbols. The UE may also receive, from the base station, a second resource assignment for a second set of symbols, where the first set of symbols and the second set of symbols include an overlapping set of symbols. The UE may modify first resources for the first resource assignment, second resources for the second resource assignment, or both. The UE may then transmit first information based on the first resource assignment.
