    Abstract: Methods, apparatus, systems and articles of manufacture to manage automotive radar coordination are disclosed. An example apparatus includes a resource manager to retrieve radar unit requirements, the radar unit requirements including at least one of a unit ID, current time information, vehicle position, and radar resource requirements, a resource multiplexer to perform at least one of time multiplexing and frequency multiplexing according to the radar resource requirements, and a resource hopper to at least perform one of frequency hopping and time hopping in response to detecting an amount of interference from other vehicles that exceeds an interference threshold.

    Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for Reference Signal Time Difference (RSTD)-based 5G-NR positioning. The processing circuitry is to determine a first PRS BW associated with a first PRS received from a first gNB associated with a first cell. A second PRS BW is determined, which is associated with a second PRS received from a second gNB of a second cell. An RSTD report resolution is determined based on the first PRS BW and the second PRS BW. A receive (Rx) timing difference between the first cell and the second cell is measured based on reception times of the first PRS and the second PRS. The measured Rx timing difference is mapped into an RSTD report for transmission to the first gNB, based on the RSTD report resolution.

    Abstract: This disclosure relates to a channel state information, CSI, acquisition circuitry, configured to: determine at least one channel covariance matrix estimate and interference-and-noise covariance matrix estimate based on at least one channel state information reference signal, CSI-RS, resource; select a restricted number of rank indicator, RI, hypotheses from a set of RI hypotheses for running a joint rank indicator-precoding matrix indicator, RI-PMI, search on the CSI-RS based channel covariance matrix estimate and interference-and-noise covariance matrix estimate to select an optimal RI value and associated PMI value, wherein the restricted number of RI hypotheses is in accordance with a run-time estimated CSI acquisition capability of the CSI acquisition circuitry; and execute the joint RI-PMI search based on the selected RI hypotheses.
