  • Patent number: 10154477
    Abstract: User equipment determines a transport block size column indicator representative of a number of resource blocks based on a number of allocated resource blocks, an adjustment factor, and a limiting factor. The transport block size column indicator is determined by applying the adjustment factor to the number of allocated resource blocks and comparing a result of applying the adjustment factor to the number of allocated resource blocks to the limiting factor. The transport block size column indicator is selected as either the result or the limiting factor as the based on the comparison.

  • Patent number: 8917587
    Abstract: A terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced.

  • Patent number: 8917628
    Abstract: A method for start-up of a network, including a number of nodes, which are connected via channels. The nodes exchange information in the form of messages via the channels. The transition phase of a synchronizing node from its initial phase to a synchronized phase is separated in a first integration phase and a second subsequent cold-start phase. A synchronizing node in the integration phase listens to messages being sent from nodes in the synchronized phase and only reacts to an integration message (i-frame) if the integration message is a valid message. Furthermore, a synchronizing node, wherein integration of the synchronizing node to a set of already synchronized nodes was not successful after a specifiable period, changes into the cold-start phase, in which a cold-start procedure of the node is extracted, wherein in the cold-start phase the node does not react to integration messages of a node in the synchronized phase.
