Patent number: 8594152Abstract: A communications network and method thereof include a base station controller configured to provide a repetition period of a primary synchronization channel to be equal to a predetermined integer value times a scrambling code length of the scrambling code of a common pilot channel. A user equipment in the network is configured to search for a known sequence comprising the primary synchronization channel to select a cell and a corresponding sub-frame/symbol timing from the selected cell.Type: GrantFiled: January 6, 2012Date of Patent: November 26, 2013Assignee: Amosmet Investments LLCInventors: Ulo Parts, Anders Ostergaard Nielsen, Kaj Jansen

Patent number: 8072929Abstract: A method of handling intercell interference applies physical layer (L1) scheduling decisions to ensure that L1 hybrid automatic repeat request (H-ARQ) retransmissions will not experience the same interference conditions. The retransmission is scheduled in a sub-frame portion that does not include previously tracked allocations of a plurality of users. Potential intercell interference is also handled by applying a time-shift of the L1 H-ARQ retransmissions, such that the bit positions impacted by inter-cell interference will change and thus assure a more robust performance.Type: GrantFiled: January 3, 2007Date of Patent: December 6, 2011Assignee: Amosmet Investments LLCInventors: Frank Frederiksen, Troels Emil Kolding

Patent number: 8031800Abstract: An arrangement for coding digital symbols and transmitting them through at least two antennas. A coder reads at least two symbols belonging to the same transmission block and forms channel symbols of the symbols of the transmission block by means of a block code. The coder multiplies at least one symbol belonging to the transmission block by a first nonzero weighting coefficient and at least one symbol belonging to the transmission block by a second nonzero weighting coefficient, and the division ratio of the first and second weighting coefficients differs from values ±1, ±j and ±1/sqrt(2). The thus formed channel symbols are transmitted to the radio path through the antennas.Type: GrantFiled: December 19, 2001Date of Patent: October 4, 2011Assignee: Amosmet Investments LLCInventor: Olav Tirkkonen

Patent number: 7991068Abstract: In a wireless MIMO communication system for N symbols of a frame of information, allocating N1 symbols to a stronger eigen sub-channel and N2 symbols to a weaker eigen sub-channel, where N1>N2; determining a probability of reception error when transmitting the N2 symbols through the weaker eigen sub-channel for an auxiliary signal-to-noise ratio; solving for a quality of service QoS of the weaker eigen sub-channel and if the QoS is less than a desired QoS, decreasing the value of N and repeating allocating symbols, determining the probability of reception error and solving for the QoS. Another aspect includes asymmetrically allocating spreading codes to a stronger eigen sub-channel and to a weaker eigen sub-channel such that the stronger eigen sub-channel is allocated more spreading codes than the weaker eigen sub-channel; and transmitting all systematic bits of turbo coded information over the stronger eigen sub-channel.Type: GrantFiled: August 18, 2009Date of Patent: August 2, 2011Assignee: Amosmet Investments LLCInventors: Dumitru M. Ionescu, Balaji Raghothaman

Patent number: RE43746Abstract: The invention relates to a method and an arrangement for transmitting a digital signal consisting of symbols, which arrangement comprises a coder (308) for coding complex symbols to channel symbols in blocks having the length of a given K, means (312) for transmitting the channel symbols via several different channels and two or more antennas (314 to 318). The coder (308) is arranged to code the symbols using a code matrix, which can be expressed as a sum of 2K elements, in which each element is a product of a symbol or symbol complex conjugate to be transmitted and a N×N representation matrix of a complexified anti-commutator algebra, extended by a unit element, and in which each matrix is used at most once in the formation of the code matrix. A code matrix is also provided which is formed by matrices of a portion of the symbols placed on the diagonal of the code matrix and by matrices of a second portion of symbols along the anti-diagonal of the code matrix.Type: GrantFiled: June 22, 2011Date of Patent: October 16, 2012Assignee: Amosmet Investments LLCInventors: Ari Hottinen, Olav Tirkkonen

Patent number: RE44191Abstract: A method, a system, electric devices applying the method, and computer programs implementing the method are provided. According to the invention, a second set of information is communicated between electric devices over a wireless proximity interface, the second set of information being associated with a second user application of the second electric device. A correspondence indicator value characterizing the readiness of a first electric device and the second electric device to execute at least one command associated with a first user application and the second user application is evaluated on the basis of a first set of information and the second set of information, wherein the first set of information is associated with a first user application of the first electric device. On the basis of the correspondence indicator value, a decision is made whether to execute the at least one command.Type: GrantFiled: May 26, 2010Date of Patent: April 30, 2013Assignee: Amosmet Investments LLCInventor: Holger Hussmann
