Abstract
The invention relates to a method for operating a wireless communication interface arranged in a vehicle, in particular a motor vehicle, an apparatus for operating a wireless communication interface and a vehicle, in particular a motor vehicle, having an apparatus for operating a wireless communication interface and a control device. According to the invention, at least one uplink user data signal is taken as a basis for determining a channel quality indicator for the user data signal, so that channel quality determination is performable in the application layer independently of determination methods for the channel quality based on pilot, control or protocol signals.
Claims20
A method for operating a wireless communication interface for a radio network wherein the wireless communication interface is arranged in a motor vehicle and wherein the method is carried out while the motor vehicle is at a standstill, wherein the method comprises the acts of:
- emitting a first electromagnetic uplink user data signal by the wireless communication interface;
- and
- receiving at least one electromagnetic downlink user data signal by the communication interface,
- wherein the at least one electromagnetic downlink user data signal is emitted by a backend via the radio network, and
- wherein the at least one electromagnetic download user data signal denotes a channel quality indicator, determined by the backend, for the first electromagnetic uplink user data signal.
An apparatus for operation in a radio network having a wireless communication interface, wherein the apparatus is arranged in a motor vehicle and, while the motor vehicle is at a standstill, is set up to emit a first electromagnetic uplink user data signal by the wireless communication interface and to receive at least one electromagnetic downlink user data signal by the wireless communication interface, wherein the at least one electromagnetic downlink user data signal has been emitted by a backend via the radio network, and the at least one electromagnetic downlink user data signal denotes a channel quality indicator, determined by the backend, for the first electromagnetic uplink user data signal.
