A protocol test device for testing protocol compliance of a wireless device under test comprises a wireless interface for transmitting an outgoing RF signal to the wireless device under test and/or for receiving an incoming RF signal from the wireless device under test, a processing unit for generating messages for the outgoing RF signal based on a predefined protocol and for processing messages in the incoming RF signal based on the predefined protocol, a message log memory for storing the generated messages and the received messages, and a summary message generation unit that generates a summary log message and stores the summary log message in the message log memory, wherein the summary log message comprises information about at least one of the generated messages and/or the received messages and repetitions of the respective generated message and/or the respective received message.

Protocol test device and method for operating a protocol test device

A mobile communication test device for testing a mobile user equipment comprises a number of transmit-receive units with a signal generator, wherein the signal generator of at least one transmit-receive unit generates test signals, which rep-resent at least two different communication partners of the mobile user equipment, a number of test interfaces, which connect the transmit-receive units with the mobile user equipment and transmit the test signals to the mobile user equipment, and a test processor, which analyzes the reaction of the mobile user equipment to the transmitted test signals based on a predefined test specification.

Mobile communication test device and a corresponding method

The method is used for detection and/or removal of errors in transmission systems which comprise a transmitter unit and at least one receiver unit. The transmitter unit transmits to the receiver unit on a semi-persistent transmission resource which provides an adjustable frequency range and an adjustable time period. Furthermore, the self-repeating, semi-persistent transmission resource repeating with the period Tis rigidly assigned to the receiver unit. Following this, at least one but not all of the HARQ process numbers available for the self-repeating, semi-persistent transmission resource are reserved for the latter.
