Abstract: According to embodiments herein, the use of an SL interface in the positioning of a UE can include additional reporting from the UE or an anchor UE related to a reference signal sent via the SL interface. This information can include information regarding the received power and/or timing of the reference signal, the angle at which it was received, and orientation of a receiving UE, and various other considerations that may not be needed in a Uu interface with a base station.

Abstract: In an aspect, a communications device (e.g., UE, BS, LMF component, etc.) determines information related to a first positioning reference signal (PRS) configuration (e.g., UL-PRS configuration such as SRS-P, or DL-PRS configuration) associated with a user equipment (UE), determines information related to a first discontinuous reception (DRX) configuration associated with the UE, determines that a first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to a DRX limitation condition, and perform an action in response to the determination that the first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to the DRX limitation condition.

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.

Abstract: In an aspect, a serving BS of a UE measures ToAs of a DL-PRS from a non-serving base station of the UE and an UL-SRS-P from the UE. The serving BS transmits measurement information based on the ToA measurements of the DL-PRS and the UL-SRS-P to a position estimation entity. The position estimation entity determines a positioning estimate for the UE based in part upon the measurement information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal, the configuration signal indicating a configuration for a positioning reference signal. The UE may determine one or more properties associated with the positioning reference signal based on the configuration signal. The UE may determine an accuracy level associated with one or more timing measurements based on the one or more properties associated with the positioning reference signal, and transmit a measurement report associated with the positioning reference signal to a base station. In some examples, the measurement report may be related to the accuracy level associated with the one or more timing measurements.

Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a user equipment (UE). In some examples, the method includes obtaining a key and using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.
