Abstract

A wireless communication system, including: a plurality of time variant transmission points for communicating with a user device, UE, wherein the UE is in a tracking region, wherein the UE is configured to receive and store a list including identifiers, IDs, of time variant transmission points for the tracking region, and wherein the list includes IDs of time variant transmission points which are available or visible for the UE in the one tracking region at different times or time periods.

First claim

1 . A user device, UE, for a wireless communication system, the wireless communication system comprising a plurality of transmission points for communicating with the user device, UE, wherein the plurality of transmission points comprises at least a first transmission point and a second transmission point, at least one of the first and second transmission points is movable relative to the other transmission point,
wherein the user device, UE, is configured to communicate with at least one of the transmission points, wherein the user device, UE, is configured to store a list or to receive a signaling indicating a request based on the occurrence of an in-line interference to prevent the UE from transmission to at least one of the first and the second transmission points, and wherein the user device, UE, is configured to control an access to at least one transmission point in case the list or the signaling indicates the request to prevent the UE from transmission responsive to the list or the signaling.

2 . The user device according to claim 1 , wherein the list indicates blocked transmission points not to be accessed by the user device, UE,
wherein the list of the blocked transmission points comprises identifiers, IDs, of each transmission point associated with validity information of the transmission point, wherein the validity information indicates an access blocking period of the transmission point.

3 . The user device according to claim 2 , wherein the blocked list further comprises an expiration date for the list relating to the movement of the movable transmission point.

4 . The user device according to claim 1 , wherein the list indicates one or more blocked antenna pointing directions of the user device, UE,
wherein the blocked antenna pointing direction list comprises position information of the user device, UE, and a forbidden pointing direction of a user device antenna for communicating with the transmission point, the forbidden pointing direction corresponding to the position information.

5 . The user device according to claim 4 , wherein the blocked antenna pointing direction list further comprises an expiration date for the list relating to the movement of the movable transmission point.

6 . The user device according to claim 4 , wherein the user device is configured to receive location information indicating the location of the movable transmission point, and
to update the blocked antenna pointing list based on the received location information.

7 . The user device of claim 1 , wherein the UE is configured for receiving information indicating a position of at least one moveable transmission point, wherein the UE is configured to acquire information indicating its own position and information indicating a position of an immobile transmission point of the plurality of transmission points,
wherein the UE is configured to evaluate, if the moveable transmission point is allowed to be accessed and to contact to the moveable transmission point dependent on the list.

8 . The user device according to claim 1 , wherein the received signaling comprises identifiers of the user devices, UEs, which are blocked to communicate with the transmission point.

9 . The user device according to claim 1 , wherein the user device, UE, is configured to receive and/or store a parameter set for generating the list,
wherein the parameter set comprises at least one or more of a user device antenna configuration, a user device, UE, position, a first transmission point position, a second transmission point position and an antenna configuration of the first and second transmission points, TPs.

10 . The user device, UE, according to claim 1 , wherein the UE comprises one or more of
a mobile terminal, or stationary terminal, or cellular IoT-UE, or vehicular UE, or an IoT or narrowband IoT, NB-IoT, device, or a ground based vehicle, or an aerial vehicle, or a drone, or a moving base station, or road side unit, or a building, or a stationary base station, or a nomadic base station, or a moving ground station, or a nomadic ground station, or a stationary ground station, or any other item or device provided with network connectivity enabling the item/device to communicate using the wireless communication system.

11 . The user device, UE, according to claim 1 , wherein the UE is configured to control an access to at least one transmission point by not initiating a connection to the transmission point, TP, at least for a time duration indicated in the list.

12 . A user device, UE, for a wireless communication system, the wireless communication system comprising a plurality of transmission points for communicating with the user device, UE, wherein the plurality of transmission points comprises at least a first transmission point and a second transmission point, at least one of the first and second transmission points is movable relative to the other transmission point,
wherein the user device, UE, is configured to communicate with at least one of the transmission points, wherein the user device, UE, is able or configured to avoid selecting a moveable transmission point of the plurality of transmission points for communication based on the occurrence of an in-line interference caused by an expected constellation of the moveable transmission point with respect to an immobile transmission point of the plurality of transmission points and the UE.

13 . The user device, UE, of claim 12 , wherein the UE is configured to determine measurement values or to receive signaling indicative of at least one of:
a channel quality between the UE and at least one of the transmission points, a beginning of an expected blocking of the immobile transmission point by the moveable transmission point, a duration of the expected blocking a barred or a permitted antenna direction from UE perspective information indicating blocked UEs or UEs that are expected to be blocked wherein the UE is able or configured to avoid selecting the moveable transmission point responsive to the determined measurement value or received signaling.

14 . The user device, UE, of one of claim 12 , wherein the UE comprises an adaptable subscriber identity module being implemented to be adapted responsive to a change between a first state in which the UEs transmission to an immobile transmission point is blocked by the moveable transmission point and a second state in which the UEs transmission to the immobile transmission point is unblocked.

15 . The user device, UE, of claim 12 , wherein the UE is adapted to transmit a measurement report indicating a link quality to at least one neighboring cell of the UE wherein the system is adapted to select, for a handover of the UEs communication, a transmission point from the reported at least one neighboring cell, wherein the UE is adapted to exclude the avoided transmission point from the measurement report or to set information relating to the avoided transmission point to a predetermined value associated with the status of being an avoided transmission point.

16 . The user device, UE, of claim 1 , wherein the user device is adapted to prevent the access to the at least one transmission point by manipulating a parameter and/or a measurement value to be reported to the wireless communication system for accessing the transmission point such that the manipulated parameter and/or measurement value cause the wireless communication system to deny the access of the user device.

17 . The user device, UE, of claim 16 , wherein the user device is adapted to mani
