Abstract: Techniques for reference signaling related to transmission power controls for communication devices are discussed and provided. A user equipment (UE) receives one or more sounding reference signal (SRS) transmission power control (TPC) configuration for uplink carriers. The SRS TPC configuration can comprise a mapping from one uplink carrier to one or more component carrier sets. The UE receives, from a monitoring cell, a downlink control information (DCI) comprising a request for SRS transmission on uplink carrier(s) and/or TPC command(s) for SRS transmission on the uplink carrier(s). The UE determines uplink carrier(s) corresponding to the SRS request and/or the TPC command(s) at least based on a correspondence between the SRS TPC configurations and the one or more uplink carriers or based on starting bit information.

Abstract: In an embodiment, a first node (e.g., a UE or a BS) performs a channel response measurement on a reference signal for positioning (e.g., UL reference signal such as SRS for positioning, or a DL PRS). The first node determines, for each of a plurality of peaks detected within the channel response measurement, peak-specific information comprising at least peak magnitude data that is based on a peak magnitude relative to a reference value. The first node reports the peak-specific information for the plurality of peaks to a second node (e.g., a BS, UE, or LMF). The second node receives the peak-specific information, and determines a positioning estimate for a UE based on the peak-specific information.

Abstract: Disclosed are techniques for transmitting reference signals (RS) for positioning. A method comprises transmitting or providing an instruction to transmit a first set of RS to a user equipment (UE) in accordance with a first set of RS transmission parameters, receiving a report containing information indicating whether a measurement performed by the UE is limited by a signal-to-noise ratio (SNR) of the first set of RS or a bandwidth of the first set of RS, determining a second set of RS transmission parameters using the received report, wherein the second set of RS transmission parameters is different from the first set of RS transmission parameters, and transmitting a second set of RS to the UE in accordance with the second set of RS transmission parameters, or providing the second set of RS transmission parameters to a base station.

Abstract: Disclosed are techniques for handling an overlap between a higher priority channel and a lower priority channel. In an aspect, a transmitter node detects an overlap between an allocation of a first set of resources of a wireless communication link for transmission of the lower priority channel and an allocation of a second set of resources of the wireless communication link for transmission of the higher priority channel, removes a subset of resources from the first set of resources to generate a removed subset of resources of the first set of resources and a remaining subset of resources of the first set of resources, and transmits, to a receiver node, the lower priority channel on the remaining subset of resources, wherein the higher priority channel is transmitted on the removed subset of resources, wherein the higher priority channel or the lower priority channel is a positioning reference signal.

Abstract: Methods, systems, computer-readable media, and apparatuses for UE positioning are described. In some embodiments, a UE is configured to transmit a reference signal to a network resource for performing measurements on the reference signal and deriving the position of the UE. The timing of the reference signal is tracked at a particular precision. The precision is based on a timing accuracy that the UE can support from different timing accuracies. The different timing accuracies may be supported, each of which may have a different set of timing error limits. For example, for an angular-based positioning of the UE, a low timing accuracy may be supported. In comparison, for a timing-based positioning method, a high timing accuracy may be supported.

Abstract: Improved methods, systems, devices, or apparatus that support prioritization for potential shared data transmissions are described. In some cases, a receiving device may identify transmission parameters for shared transmissions including a scheduled shared transmission and determine resources for a potential shared transmission. The receiving device may monitor for the shared transmission(s) based on priority rules for a shared transmission and the potential shared transmission. For instance, the receiving device may be configured to receive only one of the scheduled or potential shared transmission. In some cases, the transmitting device may consider the priority rules and determine whether to transmit or drop one or more shared transmissions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, BS determines a channel state information (CSI) report field priority-based security scheme, and transmits CSI report field priority-based security scheme to UE. UE determines bit availability in CI (e.g., UCI or SCI or MAC CE) for transmission of a CSI report. UE configures, based on the CSI report field priority-based security scheme and the CI bit availability, the CSI report with first field(s) (e.g., secured with key) being secured via a key and second field(s) being unsecured (e.g., not secured with any key or secured with weaker key below strength threshold). UE transmits the CSI report to BS.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.
