Abstract: A relay station for being operative in a mobile communication system, comprising a receiver for receiving a radio signal from a source, the radio signal comprising symbols representing an encoded information, the encoded information being based on an encoding rule and comprising payload information and redundancy information. The relay station comprising a soft detector for detecting a symbol from the radio signal to obtain soft information, the soft information comprising information on the symbol and reliability information on the information on the symbol. The relay station further comprising a quantizer for quantizing the soft information to obtain quantized soft information and a transmitter for transmitting an information on the quantized soft information to a destination.

Abstract: A radio terminal includes a radio interface configured to allow radio communication with a radio base station, and a controller configured to control switching between a wake-up state in which the radio interface is turned on and a sleep state in which the radio interface is turned off. The radio terminal acquires a reference wake-up timing scheduled as a wake-up timing for switching from the sleep state to the wake-up state. The controller shifts the wake-up timing from the reference wake-up timing.

Abstract: Apparatuses, realtime-stations, computer programs, and methods for scheduling of traffic in wireless networks are provided. In one embodiment, a method is provided for scheduling of traffic in a wireless networks including real-time stations intending to send real-time traffic and best-effort stations sending best effort traffic. The method can include overhearing for a predetermined period of time the traffic by a station which intends to send real-time traffic, and if from the overhearing the station concludes that there is already a primary station transmitting real-time access markers, assuming by the station a sequence number based on the number of real-time stations which already are sending real-time traffic.

The controller shifts the wake-up timing from the reference wake-up timing.

Abstract: A radio terminal includes: a controller configured to control switching between a wake-up state in which a radio interface is turned on and a sleep-state in which the radio interface if turned off; a battery configured to accumulate electric power to be supplied to the radio interface; a remaining battery amount acquiring unit configured to acquiring a remaining battery amount being a remaining amount of electric power accumulated in the battery. The controller performs switching from the sleep state to the wake-up state, according to a communication order where own radio terminal performs radio communication. The own-terminal communication order is scheduled based on the remaining battery amount.

Abstract: A relay apparatus for relaying a data packet to be transmitted from a first partner transceiver to a second partner transceiver having a receive unit for receiving the data packet and for receiving an acknowledgement packet to be transmitted from the second partner transceiver to the first partner transceiver when the second partner transceiver has successfully received the data packet. The relay apparatus further having a help detector for providing a help indicator if a help necessitated situation is detected and a transmit unit for transmitting the data packet in response to the help indicator. The help necessitated situation is detected based on whether a first communication link between the relay apparatus and the second partner transceiver is better than a second communication link between the first and second partner transceivers, the second communication link being evaluated by an information being available from the data packet.
