    Abstract: A method for a base station includes sending a request for a report on beamforming capability to a target user equipment; receiving the report on the beamforming capability from the target user equipment; allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report; determining a beam sweeping mle based on the at least one positioning reference signal resource allocated for the target user equipment; and sending the positioning reference signal resource allocation and the beam sweeping mle to the target user equipment. A corresponding method for a user equipment includes receiving a request for a report on beamforming capability from a serving base station; sending the report on the beamforming capability to the serving base station; receiving information relating to at least one positioning reference signal resource and a beam sweeping rule from the serving base station; and performing beam sweeping on uplink positioning reference signal transmissions using the received positioning reference signal resource allocation based on the beam sweeping rule.

    Abstract: Systems, methods, apparatuses, and computer program products for using angle error groups (AEGs) to improve angle of arrival (AoA) positioning may be provided. For example, for a specific received signal, one or more receiving antenna elements that can be considered to have almost the same incident angle within a certain margin may be defined as a group. The group of receive (Rx) antenna elements (or a group of Rx antennas) may be defined as an AEG. The configuration of an AEG for each TRP and the AEG may be used for AoA measurement and reporting. The gNB or transmit receive point (TRP) may perform AoA measurements and may determine an AoA for the AEGs.

    Abstract: According to an example embodiment, a method may include receiving, by a user equipment from a base station associated with a cell, control information assigning a subframe as a preconfigured uplink resource (PUR) subframe for the user equipment, the preconfigured uplink resource (PUR) subframe including an extended cyclic prefix, the control information indicating resources allocated to the user equipment for uplink transmission within the preconfigured uplink resource (PUR) subframe, wherein one or more other subframes for use by the user equipment include a normal cyclic prefix that is shorter in time than the extended cyclic prefix of the preconfigured uplink resource (PUR) subframe; and transmitting, by the user equipment, data via the resources allocated to the user equipment within the preconfigured uplink resource (PUR) subframe.

    Abstract: An apparatus, method and computer program is described comprising: receiving downlink positioning signals from each of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein each downlink positioning signal is received from a downlink beam direction for the respective communication node; determining an angle of arrival and/or a time of arrival for each of the received downlink positioning signals; and determining an uplink positioning signal beam configuration based, at least in part, on the determined angle of arrival and/or the determined time of arrival for said received downlink positioning signals.
