Patent number: 8934935Abstract: 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.Type: GrantFiled: June 10, 2005Date of Patent: January 13, 2015Assignee: Nokia CorporationInventors: Harri Holma, Hannu Häkkinen

Patent number: 7489691Abstract: 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.Type: GrantFiled: December 23, 2002Date of Patent: February 10, 2009Assignee: Nokia CorporationInventors: Jeroen Wigard, Troels Kolding, Preben Mogensen, Pablo Ameigeiras, Woonhee Hwang, Hannu Häkkinen

Patent number: 7095290Abstract: 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.Type: GrantFiled: December 18, 2001Date of Patent: August 22, 2006Assignee: Nokia CorporationInventors: Hannu Häkkinen, Pekka Kyösti

Patent number: 7069038Abstract: 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.Type: GrantFiled: February 12, 2004Date of Patent: June 27, 2006Assignee: Nokia CorporationInventors: Hannu Häkkinen, Antti Toskala

Patent number: 6763011Abstract: 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.Type: GrantFiled: October 5, 2000Date of Patent: July 13, 2004Assignee: Nokia Mobile Phones, Ltd.Inventors: Hannu Häkkinen, Kari Pehkonen, Esa Malkamäki

Patent number: 6650655Abstract: 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.Type: GrantFiled: March 27, 2000Date of Patent: November 18, 2003Assignee: Nokia CorporationInventors: Antero Alvesalo, Mika Rinne, Hannu Hakkinen, Oscar Salonaho

Patent number: 6594495Abstract: 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.Type: GrantFiled: October 3, 2001Date of Patent: July 15, 2003Assignee: Nokia CorporationInventors: Oscar Salonaho, Hannu Häkkinen, Seppo Granlund

Patent number: 6567459Abstract: 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.Type: GrantFiled: November 8, 1999Date of Patent: May 20, 2003Assignee: Nokia CorporationInventors: Hannu Häkkinen, Harri Holma
