Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive a signal including one or more channel transmission parts associated with one or more zones. The UE may identify, based on receiving the signal, at least one zone of the one or more zones that is associated with the UE. Additionally or alternatively, the UE may identify multiple zones of the one or more zones that are associated with the UE. The UE may select a channel transmission part of the one or more channel transmission parts based on receiving the signal and the identified zone associated with the UE. The UE may decode the one or more selected channel transmission parts, and may communicate based on the decoded channel transmission part or the decoded channel transmission parts.

Abstract: Disclosed are techniques for determining a line-of-sight (LOS) path between a transmitter and a wireless device. In an aspect, a wireless device receives a first reference signal on a first frequency band at a first time, receives a second reference signal on a second frequency band at a second time, compares the first time to the second time, and determines, at least based on the comparison of the first time to the second time, which of the first reference signal and/or the second reference signal followed the LOS path between the transmitter and the wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a mode for processing a transport block from a base station. The UE may receive a transport block from the base station. In some examples, the transport block may include one or more code blocks in a first code block group and one or more code blocks in a second code block group and may decode the one or more code blocks in the first code block group of the transport block. In some examples, the UE may deliver, to the medium access control (MAC) layer of the UE and based on the mode for processing the transport block, the one or more decoded code blocks in the first code block group before completing the decoding of the second code block group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

Abstract: In a positioning session for a user equipment (UE), one or more base stations may receive and derive positioning measurements from uplink (UL) transmission from the UE that include a physical resource block (PRB) interlaced waveform based on at least one of interlaced physical uplink control channel (PUCCH) resource blocks, interlaced physical uplink shared channel (PUSCH) RBs resource blocks, interlaced sounding reference signal (SRS), interlaced uplink (UL) positioning reference signal (PRS), or a combination thereof. The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements. The base station may report the positioning measurements along with the channel used and enhanced accuracy requirements to a location server for positioning.

Abstract: Aspects of the present disclosure disclose various methods for grouping network resources into precoder resource groups (PRGs) for precoding in MIMO communication. A user equipment (UE) may select a common precoder that may not be restricted to a codebook for precoding the resources in the same PRG. These resource grouping methods provide the UE with the flexibility to select a precoder that is well suited to the channel or bandwidth. Moreover, the base station may reduce downlink signaling because it does not need to signal the precoder choice to the UE. In some examples, the base station may receive PRG based channel state information feedback that facilitates DL precoding. Other aspects, embodiments, and features are also claimed and described.

Abstract: Disclosed are techniques for determining locations of reference nodes. In an aspect, an apparatus transmits a request to a first reference node to perform a first round-trip-time (RTT) procedure with a second reference node, determines a first distance between the first reference node and the second reference node based on the RTT procedure, determines relative locations of the first and second reference nodes with respect to each other, and determines absolute locations of the first and second reference nodes from their relative locations based on at least one of the first and second reference nodes having a known absolute location and at least one known angle-of-arrival (AoA) or angle-of-departure (AoD) of at least one reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a measurement operation to attain multiple measurements to report to a base station. The measurements may correspond to a first number of bits if reported. The UE may compress the measurements using an encoder neural network (NN) to obtain an encoder output indicating the measurements. This encoder output may include a second number of bits that is less than the first number of bits. The UE may report the encoder output to the base station in this compressed form. At the base station, the encoder output may be decompressed according to a decoder NN. Once the base station decompresses the encoder output, the UE and base station may communicate according to the measurements determined from the decompression. In some cases, the base station may perform load redistribution based on the measurements.
