Abstract: Systems and processes for position estimation for emitters outside of line of sight of fixed network nodes are disclosed. The positions of the mobile nodes are determined and the mobile nodes are time synchronized. Then, locations of one or more user equipments (UEs) are determined. The mobile radio network nodes may be air, land, or water-borne (e.g., mounted on drones, trains, boats, planes, automobiles, or the like). The UEs to be located may be a wide range of devices such as emergency transmitters, mobile phones, simple sensor nodes, and other Internet of Things (IoT) devices.

Abstract: Apparatuses and methods are disclosed for block interleaving. In one embodiment, a method includes generating an interleaver sequence for a control resource set, CORESET, configuration for a physical downlink control channel, the interleaver sequence associated with an interleaving matrix; optionally, for each one of an allowed value of number of rows for the interleaving matrix, determining a number of null entries to be added to the interleaving matrix; and selecting a number of rows. R, for the interleaving matrix such that the number of null entries to be added to the interleaving matrix is: no more than a number of columns, C, of the interleaving matrix; and optionally, the smallest among the numbers of null entries determined for each of the allowed values of number of rows for the interleaving matrix. In another embodiment, a method includes decomposing the interleaver sequence.

Abstract: Methods and device for use in a wireless device of reporting positioning measurements comprises receiving network assistance information from a network node. The network assistance information is for assisting the wireless device in performing Observed Time Difference Of Arrival (OTDOA), and comprises: a list of reference cells; a list of neighbor cells; and a rule for terminating Reference Signal Time Difference (RSTD) measurements. The method further comprises performing RSTD measurement between a cell in the reference cell list and a cell in the neighbor cell list. Upon determining the RSTD measurement satisfies the rule for terminating RSTD measurements, the method includes reporting the RSTD measurements to the network node. Upon determining the RSTD measurement does not satisfy the rule for terminating RSTD measurements, performing another RSTD measurement between the cell in the reference cell list and a cell in the neighbor cell list.

Abstract: A method and apparatus for design and optimization of a network are described. A first deep neural network is used to obtain a function that represents a relationship between design parameters of the network and network performance metrics of the network. A second deep neural network is used to obtain a subset of one or more candidate network deployment configurations that optimize the performance metrics for the network. An optimal candidate network deployment configuration for the network is selected from the subset of candidate network deployment configurations wherein the optimal candidate network deployment configuration maximizes performance of the network as defined based on the performance metrics.
