摘要:
A measuring device for testing mobile-radio relay stations provides at least one antenna and a processing unit. A base station or a mobile station transmits a first signal to a relay station. The relay station generates a second signal derived from the first signal and transmits it. The antenna of the measuring device receives the first signal and the second signal. The processing unit of the measuring device compares the received signals.

摘要:
A method for testing transmission modes of a wireless communication device. According to the method, a switching range is determined in a parameter space in a test device. The parameter of the parameter space describes the quality of transmission and influences a recommendation for a transmission mode to be adjusted in a device to be tested. The switching range is a subspace of the parameter space and contains at least one switching limit for the recommendation for the subsequent transmission mode to be adjusted. In a further step, random parameter points from the switching range are generated depending on a probability distribution which is defined for the switching range. A signal is generated for every parameter point and has a transmission mode determined by the parameter point and is transmitted to the device to be tested. The device to be tested then transmits one response signal per received signal to the test device, the response signal containing a recommendation for a subsequent transmission mode to be adjusted. All recommendations from all received response signals are evaluated in the test device.

A method for reducing collisions during the initial access by a plurality of mobile-terminal devices to a base station which comprises a control unit, wherein the control unit administers at least one random-access resource, wherein the method contains the following method steps: setting (S1) by the control unit of a priority which specifies which mobile-terminal device is allowed to connect to the at least one random-access resource; broadcast (S2) of the priority by the base station on at least one known channel.
