  • Patent number: 9686068
    Abstract: A method, user equipment, network device, and software product employ indicators from a plurality of respective cells to indicate a difference, if any, regarding allocation in the respective cell as compared to neighbor cells. Mobility measurements are then performed according to the indicators, and also on the basis of configuration of a cell where the measurements are performed.

  • Patent number: 8274960
    Abstract: In one non-limiting, exemplary embodiment, a method includes: receiving a message including a resource allocation map having a first portion and a second portion; utilizing the first portion to determine a specific mapping scheme of a plurality of mapping schemes, wherein the determined specific mapping scheme is used for the second portion; and obtaining, based on the determined specific mapping scheme, resource allocation information based on the second portion. In another non-limiting, exemplary embodiment, a method includes: generating a message including a resource allocation map having a first portion and a second portion, wherein the first portion is indicative of a specific mapping scheme of a plurality of mapping schemes that are applicable to the second portion; and transmitting the generated message.

  • Patent number: 7940795
    Abstract: Introducing a set of limitations on where different payload sizes are allowed in a control channel element aggregation ‘tree’ is shown. Following these limitations, the network element (e.g. Node B) will have a large flexibility for scheduling users, while the terminal (e.g. User Equipment) will have an option for still keeping the number of blind decoding attempts at a quite low number.

  • Patent number: 7706469
    Abstract: A method of transmitting a transmit vector comprising symbols to be delivered within a resource unit from a transmitting station with one or more transmit antennas to one or more receiving stations with one or more receive antennas. The method comprises obtaining information on the state of channels between the one or more transmit antennas and the one or more receive antennas; and computing, on the basis of the channel states between the one or more transmit antennas and the one or more receive antennas, a covariance matrix Rnn, a combined channel matrix H, and a block-diagonal linear operator V of decoding matrices of the receiving stations. The transmit vector is multiplied with a precoding matrix P fulfilling the equations (HHVHVH=?I)P=HHVH Vi(HiPPHHiH+Rnn,i)=PiHHiH, i=1 . . . K trace(PHP)=Ptr and corresponding performing filtering in the receiving station using a receiver filter corresponding to the block-diagonal linear operator V.
