摘要： The present invention relates to a method and system for scheduling data packets in a base station device of an access network. An information indicating a retransmission status of a data packet is provided to the base station device, and a scheduling priority is allocated to the data packet based on the retransmission status information. Thereby, retransmission packets can be scheduled earlier and round trip times can be reduced, so as to decrease the risk of timeouts and stalling and to loosen buffer requirements.

摘要： The invention relates to a method for load control and a radio system. In the invention a load result describing the load is cell-specifically formed. The load result is formed either by comparing a signal strength of desired signals and a combined total strength of interferences and the desired signals or by weighting a signal-to-interference ratio with a bandwidth or a data transmission rate. The load result is compared with a threshold value of the highest load level allowed of a cell. The data transmission rate in the cell is increased if the load result is smaller than the threshold value. The data transmission rate in the cell is reduced and the establishment of new connections is avoided if the load result exceeds the threshold value. In heavy load situations a signal-to-interference objective is also changed in order to balance the load result.

摘要： The invention relates to a power control method in a mobile communications system in which transmission of a signal of one logical connection over the radio path employs hopping, such as frequency hopping, antenna hopping or timeslot hopping. According to the present invention, the method is characterized in that the quality of the signal received on the radio connection is determined on one hopping setting, such as frequency, antenna or timeslot, and the power control is carried out on the radio connection in question from hopping setting to hopping setting so that the transmission power of at least one hopping setting, such as frequency, differs from the transmission power of at least one other hopping setting, such as frequency, used on the same radio connection.

摘要： System and methods for improved uplink signal detection where when a mobile device detects signaling indicating the presence of a packet for that mobile device from a network node, the mobile device may transmit one or more NACKs in a sub-frame before the one in which the mobile device would transmit the normal ACK/NACK for the packet. Additionally, the mobile device may transmit one or more NACKs in the sub-frame immediately following the normal ACK/NACK for a packet (unless a packet was transmitted in the immediately following sub-frame and successfully decoded by the mobile device, in which case an ACK would obviously be transmitted). Therefore, extra uplink (UL) interference is eliminated. Moreover, the amount that a network node must offset its ACK/NACK decision threshold is significantly reduced. This results in a reduction of required ACK power by a mobile device.

摘要： The invention relates to a method for load control and a radio system. In the invention a load result describing the load is cell-specifically formed. The load result is formed either by comparing a signal strength of desired signals (23) and a combined total strength of interferences (13) and the desired signals (23) or by weighting a signal-to-interference ration with a bandwidth or a data transmission rate. The load result is compared with a threshold value of the highest load level allowed of a cell (1). The data transmission rate in the cell (1) is increased if the load result is smaller than the threshold value. The data transmission rate in the cell (1) is reduced and the establishment of new connections is avoided if the load result exceeds the threshold value. In heavy load situations a signal-to-interference objective is also changed in order to balance the load result.

摘要： The invention relates to a method for transmitting packet switched data in a mobile communications system using an ARQ protocol. In the method the receiver requests, if necessary, retrasnmissions of the originally sent transmission unit, until the quality of the combined transmission unit formed of the originally sent transmission unit and its retransmitted copies corresponds to the predetermined quality level. The signal is not detected until after this. If the packet is interleaved and encoded and it is found out that the packet is not faultless, retransmissions of the transmission units of the packet that are of the poorer quality are requested. The invention also relates to a mobile communications system implementing the method of the invention.

摘要： The invention relates to a transmitting and receiving method and a radio system. In a transmitter the signals to be transmitted are spread coded in means and modulated by subcarriers in means. In a receiver (R) the signals are demodulated in means and submitted to multiuser detection in means by using the subcarriers to limit the number of detectable signals in the means. The receiver uses multiuser detection for reducing multiple access interference and correcting frequency-selective fading.

摘要： A cellular radio system and a handover method in a cellular radio system is provided. The cellular radio system includes a subscriber terminal and a base station. In the system, the subscriber terminal maintains and continuously updates an active set of base stations. One or several base stations belonging to the active set has a connection or connection set-up facilities to the subscriber terminal. The subscriber terminal controls the downlink transmission of one or several base stations of the active set by switching the transmission of the base station on or off. This method provides a fast soft handover similar to a hard handover.

摘要： A communications system where data blocks from a communications device are received at least in a serving site over a wireless interface. The serving site typically checks whether data blocks have been correctly received and sends acknowledgement information to the communications device accordingly. An assisting site may also receive the data blocks and send information indicating whether data blocks have been correctly received in the assisting site. In this case, the serving site may request erroneously received information from the assisting site. Alternatively, the assisting site may send information indicating erroneous reception of data blocks in response to noticing a data block sent by the communications device. As a further alternative, the assisting site may be synchronized with the data blocks sent by the communications device and send quality information relating to the wireless interface between the communications device and the assisting site to the serving site.
