Abstract: A method for preparing for the start-up of a control unit for access devices, wherein at least one access device is communicatively connected to the control unit, wherein the control unit has a communication interface for information technology communication with a mobile terminal and/or has an input device for detecting an input from an installer or is in communicative connection with an input device for detecting an input from an installer. The method includes: a) detecting, using the control unit, an information technology signal or a change in an existing information technology continuous signal of a mobile terminal by the communication interface, and/or detecting an input from an installer using the input device, b) sending a trigger signal from the control unit to the access device, c) receiving the trigger signal using the access device, and d) performing an action using the access device depending on the received trigger signal.

Abstract: A method for commissioning a door system, with the door system having at least one door component, with the commissioning including the following method step carrying out an electronically defined test process of the door system wherein the test process includes test steps and/or test functions, wherein the sequence of the test steps and/or test functions is stored electronically in the test process, wherein the test process is defined for a preconfigured door system type.

Abstract: A door system for at least one door, the door system including door components, with one of the components being designed as a control unit. The control unit and at least one other door component are connected to one another via a first communication bus. An access system with an above door system and with a computing unit are related, with an image of the door system stored in the computing unit, the door components connected to the first communication bus each having an identifier. The identifiers are stored as part of the image of the door system in the computing unit and/or with past and current operating states of the door system stored in the computing unit. An access system with at least one of the above door systems is related, with at least one door system having an authentication device configured to receive an access attribute for authentication.

Abstract: A method for commissioning a door system with the door system having door components, with at least one door component being designed as a control unit, with the method including the following steps: storing an electronic configuration of the door system in the control unit and/or a mobile terminal, and carrying out at least one commissioning step by the electronic configuration.

Abstract: A method for installing door components includes at least the following steps: a. providing at least one preconfigured door system type by way of an electronic configuration system for selection by a user, wherein the at least one preconfigured door system type is able to be retrieved from a database by way of the electronic configuration system, wherein at least one preconfigured door system type is able to be preselected by the configuration system by way of at least one technical and/or functional user specification, wherein the door system type contains stipulated door component types, and b. electronically providing preconfigured technical data of the selected door system type in order to carry out the installation on site.

Abstract: A communication device is described comprising a transmitter configured to transmit data according to a retransmission protocol, a determiner configured to determine whether, for a transmission time scheduled according to the retransmission protocol, there was a transmission gap within a predetermined time interval before the transmission time or to determine whether there will be a transmission gap within a predetermined time interval after the transmission time and a controller configured to control the transmitter to perform an initial transmission of data or a retransmission of data according to the retransmission protocol at the transmission time based on the result of the determination.

Abstract: A method for estimating channel state information (CSI) for a communication channel is disclosed. Theoretical channel capacities are calculated using combinations of rank indicator (RI) and precoding matrix index (PMI) values. A number of these theoretical channel capacities are selected and used for determining an optimum combination of channel quality indicator (CQI) values, RI values and PMI values. This combination of values is subsequently transmitted as CSI.
