Abstract: Systems and methods for measuring at and reporting by a target user equipment (UE) of one or more positioning signals sent from one or more assisting UEs to the target UE are disclosed herein. The target UE may receive a positioning signal from an assisting UE according to a communication received at the target UE. The target UE may proceed to perform a positioning measurement using the positioning signal received from the target UE. The positioning measurement may be used by the target UE to estimate its own position, or the positioning measurement may be sent to another entity within a wireless communications system to be used in estimating the physical position of the UE. The handling of multiple received positioning signals from various sources, and the handling of situations where, for example, a transmission reception point (TRP) and an assisting UE may schedule overlapping positioning signals, are also discussed.

Abstract: Providing coverage enhancements for a user equipment (UE) includes decoding a random access channel (RACH) preamble received from a user equipment (UE) via a physical random access channel (PRACH). A number of repetitions associated with transmitting a random access response (RAR) over a physical downlink shared channel (PDSCH) may be determined in response to the RACH preamble. A transmission for the UE to be sent over a physical downlink control channel (PDCCH) may be encoded. The transmission may indicate the number of repetitions to the UE using one or more reserved bits of a downlink control information (DCI).

Abstract: A user equipment (UE) configured to report Channel State Information (CSI) to a wireless network. The UE transmits a first sounding reference signal (SRS) on an uplink (UL) channel, receives a first channel state information reference signal (CSI-RS) on a downlink (DL) channel, wherein the first CSI-RS includes a first configuration of CSI-RS parameters based on the first SRS, performs first CSI-RS measurements based on the first configuration of CSI-RS parameters, transmits a first CSI report including the first CSI-RS measurements, transmits a second SRS on the UL channel, receives a second CSI-RS on the DL channel, wherein the second CSI-RS includes a second configuration of CSI-RS parameters based on the second SRS, performs second CSI-RS measurements based on the second configuration of CSI-RS parameters and transmits a second CSI report including the second CSI-RS measurements.

Abstract: A user equipment is configured to receive a reference signal when secondary cell (SCell is to be activated. The UE receives a secondary cell (SCell) activation indication for activating an SCell, receives a reference signal (RS) triggering indication for triggering an RS prior to an expected SCell activation period, performs measurements on the triggered RS and activates the SCell based on the RS measurements.

Abstract: This disclosure relates to techniques for performing wireless communications by a network in communication with a UE that is moving rapidly. The network may adapt communication techniques in response to the UEs motion. For example, reference signals may be transmitted to the UE from additional transmission and reception points and/or using different configurations.

Abstract: A user equipment (UE) receives scheduling information from a base station of a wireless network. The UE monitors a first physical resource to receive a common downlink control information (DCI) portion of scheduling information for the UE, decodes the common DCI portion to determine information for a UE-specific DCI portion that is transmitted by the base station on a second physical resource, monitors the second physical resource for the UE-specific DCI portion based on at least the information from the common DCI and decodes the UE-specific DCI portion based on at least the information from the common DCI.

Abstract: A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.
