Abstract: The present invention relates to an apparatus and a method for detecting presence of data, wherein input data is decoded using a decoder metric to obtain decoded data, and an error check is performed for the decoded data. Furthermore, a threshold value is determined based on an obtained maximum value that the decoder metric can assume for the input data, and the threshold value is compared with an actual value of the decoder metric. Presence of the input data is then decided based on results of the error check and the comparison.

Abstract: Aspects of the present invention include methods, apparatuses and systems that may be used for radio frequency and performance testing of communication equipment in a telecommunications network. According to one aspect of the invention, received data may be discarded during a test whenever a device being testing is unable to store the data, for example in a buffer. According to another aspect of the invention, the device being tested will provide data for transmission processing whenever there is an opportunity during the testing to transmit data, thus allowing the device to be aggressive in its data transmission.

Abstract: A method of determining the availability of at least one of a plurality of different services in a wireless communication network comprising at least a first station and a second station which are in communication has the following steps. The pathloss between said first station and said second station is estimated, and based on the pathloss and the requirements of at least one of said services, the power with which said first station is required to transmit to said second station is determined. The required power is compared with the maximum power with which the first station is capable of transmitting.
