摘要: The present invention relates to a device and a method for packet switching in a cellular radio communication system. Radio stations that have packets to transmit, transmit packets with a particular transmission probability (Si,n). The fraction of the transmitted packets that are received correctly by the receiving radio station, the so-called throughput fraction (ti,n), can be calculated. The transmission probability (Si,n) for a transmitting radio station is continuously updated according to a mapping function (f(a)) that depends on the value of the throughput fraction (ti,n). According to the invention a mapping function (f(a)), with a derivative with an absolute value less than one, is chosen (201). Starting values of the throughput fraction (ti,n) are generated (203) and these values are input to the mapping function. Updated values of the transmission probability (Si,n) are generated (204) by mapping function. The transmitting radio station transmits (205) packets according to the updated transmission probability, whereby a new value of the throughput fraction is generated (206). The method is repeated until the values of the throughput fraction are stable.

摘要: One method for controlling operation of a repeater in radio communication system comprises determination whether operation of a node in the radio communication system benefits from assistance of a repeater and transmitting, from the node in the radio communication system, a radio signal to the repeater being indicative of an order to promptly activate the repeater if the benefit exists. One complementary method for controlling operation of a repeater in radio communication system comprises detection (252), in the repeater, of a radio signal being indicative of an order to activate the repeater. Amplification in the repeater is activated (254) as a response to such a detected radio signal and uplink traffic from a user terminal being located in a vicinity of the repeater and/or downlink traffic to the user terminal is amplified (256). A repeater, a node, a user terminal and a system operating according to the method are presented.

摘要: In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. A method for extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change in the near future for a considered mobile station in the near future. A measurement report is sent from the mobile station to the base station. The quality measure in the measurement report is filtered over the area by a smoothing filter (220), and then processed through an updating filter (230) resulting in a time varying map (240). Several maps are classified (260). Classified data are grouped (270) resulting in the final map, which is stored in a database (280). The final map may be used to enhance the performance of radio network algorithms.

摘要: A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function P based on a terminal identification (K)). The cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames. A communication module (600c) then communicates with the second mobile terminal (602), either by transmission or reception of the data, on the determined resource element (RE).

摘要: According to the invention a receiving end terminal (RET) enters a delay mode based on the detecting of the quality of the link being lower than a threshold. In this delay mode, the receiving end terminal provides a reception delay indicator (RDI) for a sending end terminal (SET). The sending end terminal (SET) receives the reception delay indicator (RDI) and provides an end of speech indicator (ESI) for the receiving end terminal (RET) at an end of a speech coding interval (SC). The receiving end terminal (RET) uses the reception delay indicator (RDI) and end of speech indicator (ESI) to define a first time interval (AL1) during which a speech decoder is disabled. The speech decoder is again activated after the first time interval (AL1).
