Abstract: An apparatus including at least one processor; and at least one memory including computer program code which, when executed by the at least one processor, causes the apparatus to receive reference data usable for estimating a geographic position of the apparatus based on its distance from two or more base stations, and to receive updated reference data for at least one of the base stations and to determine an initial geographic position (UEinit) of the apparatus using the received reference data for a plurality of the base stations, including any updated reference data, and to establish a bidirectional communications link with at least one of the base stations.

Abstract: A disclosed method includes receiving a time-of-arrival range filter configuration and a reference signal physical transmission time from a network node at a reference signal physical reception time. The time-of-arrival range filter configuration includes at least one of a time-of-arrival filter status, a time-of-arrival filter distance range, and a time-of-arrival configuration. A time difference between the reference signal physical reception time and the reference signal physical transmission time is determined, and a distance to the network node based on the time difference is calculated. Whether the distance is within the time-of-arrival filter distance range is determined, and the time-of-arrival filter status is determined. Based on the time-of-arrival filter status, actions are performed in accordance with the time-of-arrival configuration applicable for the distance.

Abstract: Example embodiments provide a method to determine a reference signal transmission delay by a base station for a distributed RAN or cloud system architecture. The method uses an over the air transmission time and compensates for a possible reference clock discrepancy. Further, a method for TOA-based propagation delay measurement is provided, where consecutive reference signal transmission delays have a variable pattern or high precision is needed. Apparatuses, methods, and computer programs are disclosed.

Abstract: An apparatus and method is disclosed. The apparatus may comprise at least one processor, and at least one memory including computer program code which, when executed by the at least one processor, causes the apparatus to receive at an apparatus, from each of at least three remote base stations, transmitted data comprising a portion indicating the geographic position of the respective base station and a transmission time of a reference signal or data. The apparatus may also be caused to determine the geographic position of the apparatus based on the received geographic positions and the delay between the transmission time and a reception time of the reference signal or data.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for using time of arrival (TOA) based TTOAVAL or TTOA value for uplink to downlink channel synchronization at a user equipment (UE) required for required for establishing an RRC connection and/or maintaining the RRC connection due to UE mobility. In an example implementation, the method may include determining, by a user equipment (UE), a first time of arrival (TOA) based timing advance index value; and performing, by the user equipment (UE), uplink channel synchronization based at least on the first time of arrival (TOA) based timing advance index value.

Abstract: A method may include determining a timing advance-limited cell maximum range based on a requested preamble format broadcasted by a network node. The method may also include in response to the user equipment being outside of the timing advance-limited cell maximum range, sending a random access preamble with an initial uplink channel timing adjustment to fit an indicated subframe dedicated for a hearing window. The method may also include in response to the user equipment being outside of the timing advance-limited cell maximum range, additional timing adjustment for any uplink transmission in order to maintain uplink to downlink channel synchronization. In a variant, the method may also include in response to the user equipment being outside of the timing advance-limited cell maximum range, additional timing adjustment for any uplink transmission in order to maintain uplink to downlink channel synchronization.

Abstract: A base station may be configured to support distance filtering. When the distance filtering is on, a base station may, when it receives a service request from a device, determine from timing information in the service request at least a distance to the device, then determine a filtering sub-area for the device based on the distance; and to apply one or more filtering rules defined for the filtering sub-area to determine how to process the service request.

Abstract: Apparatuses and methods for monitoring network timing are disclosed. A method comprises storing (300) information on a reference propagation delay between the apparatus and one or more radio access nodes, controlling (302) reception of a reference signal from one or more radio access nodes, the reference signal comprising information on the transmission time instant of the signal, determining (304) the reception time instant of the reference signal, determining (306) the propagation delay of the reference signal based on the time difference of the reception time instant and the transmission time instant, and determining (308) correctness of time references of the apparatus and the one or more radio access nodes based on the determined and stored propagation delays.
