  • Patent number: 8934935
    Abstract: 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.

  • Patent number: 7489691
    Abstract: 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.

  • Patent number: 7116651
    Abstract: A method (100) and corresponding equipment, the method for enabling a Node B/base station (14) to distinguish different states—HARQ active states and a DTX (non-transmitting) state—of a UE (12) in respect to use of the feedback HSDPA (high-speed downlink packet access) channel HS-DPCCH over which the UE (12) sends acknowledgement messages (ACK/NACK) to the Node B (14) in response to receiving packets via the HSDPA (downlink) data channel HS-DPCH, the method including steps (41 42) in which the UE (12) additionally sends preamble symbols if an acknowledgement message (ACK/NACK) is to be sent in a next time interval but not in the current time interval, and at least one postamble symbol prior to the UE (12) entering the non-transmitting state (DTX).

  • Patent number: 7095290
    Abstract: Method and system for generating higher order modulations with QPSK modulators. A complex sequence of binary digits is input to QPSK modulators. The binary digits are mapped to constellation points and multiplied with weighting coefficient. Constellation points of higher order modulation are mapped to inputs of the QPSK modulator, and, after modulation QPSK symbols are summed to compose symbols of higher order modulation.

  • Patent number: 7069038
    Abstract: 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.

  • Patent number: 6763011
    Abstract: A method and an arrangement are provided for timing a change of diversity weights in a radio connection between a base station and a terminal. A response timing mode is selected from a number of predefined response timing modes. The terminal is informed about the selected response timing mode. An initiation is received from the terminal and it is responded to the initiation by changing certain diversity weights so that the exact moment of time for effecting the change is determined by the selected response timing mode.

  • Patent number: 6650655
    Abstract: The idea of the invention is the allocation of transmission resources in several separate steps. In the first step, the available transmission resources are dynamically divided between the different networks. In the second step, the networks divide the resources that have been allocated for their use among their users by their own channel allocation methods. In one embodiment, a given minimum capacity wherewith the network achieves a predetermined minimum quality of service is permanently allocated to some or all of the networks. As the capacity requirement increases, the necessary amount of additional capacity is allocated to the operator in excess of this minimum capacity. The additional capacity is then allocated either from resources separately reserved for this purpose that are common to the networks, or by borrowing it from capacity that is allocated to another network but falls outside the minimum capacity of said network.

  • Patent number: 6594495
    Abstract: 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.

  • Patent number: 6567459
    Abstract: 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.

  • Patent number: 6539236
    Abstract: A connection establishment method for establishing a random access type connection using a random access channel, which is used in a radio system having several subscriber terminal equipments (37 to 38) and base stations (33 to 36) where one or more transceiver units (40 to 47) operate, and in which system connection establishment between one of the subscriber terminal equipments (37 to 38) and the base station (33 to 36) is possible when the one subscriber terminal equip nt (37 to 38) is situated in the coverage area of one or more transceiver units (40 to 47) of the base station, where the one subscriber terminal equipment (3 to 38) evaluates the quality of the connections to be established. Starting from a condition in which no connection is established with the one subscriber terminal equipment, the one subscriber terminal equipment (37 to 38) forms a random access type connection to more than one base station transceiver unit (40 to 47) included in one or more base stations (33 to 38).
