  • Patent number: 9451301
    Abstract: A method for mapping resources of broadcast control channel is disclosed. Available subcarriers of a subframe in which the broadcast control channel is located are divided into three subcarrier sets, each of which is mapped to be one frequency partition, so that the subframe in which the broadcast control channel is located includes N frequency partitions, and resources of each frequency partition are mapped to be logical resource units, wherein N can be 1 or 3. With this method, subcarrier sets of the broadcast control channel are divided, and the resources of the broadcast control channel are mapped.

In particular the vaccines and immunogenic compositions of the present invention relate to flagellin-antigen fusion proteins in which the spatial orientation of the flagellin to antigen and the charge distribution of the antigen is optimized to enhance immunogenicity and/or reduce reactogenicity. The present invention also relates to methods of evaluating the vaccines by measuring the relative expression of certain gene markers. Altered expression of the genes relative to flagellin control sample may indicate that the vaccine is suitable to stimulate an adaptive immune response to the antigen component in the subject with minimal side effects.

  • Patent number: 8553642
    Abstract: The present invention discloses a method for solving non-controllability of terminal's power spectrum density in OFDMA system. It considers the problem of non-controllability of terminal's carrier transmit power resulting from the indeterminacy of carrier number allocation to the terminal in the OFDMA system which is solved by introducing the maximum carrier number that can be allocated to the terminal by combing AMC, the power control and the dispatching. By applying the present invention, the carrier power of the terminal can be best controlled by the system, it is most possible for the terminal to transmit power on carrier completely according to a set value, while it is greatly reduced the possibility that the terminal's power spectrum density is suddenly decreased out of control, which is caused by the summation of carrier powers in the set value exceeding the maximum total transmit power.
