  • METHOD FOR SECURELY TRANSMITTING PACKETS FOR WIRELESS TELECOMMUNICATIONS SYSTEM
    Publication number: 20110274277
    Abstract: The invention relates to a method for securely transmitting packets on a wireless link. This method advantageously uses a type II HARQ protocol. In a first step (110), a first version of a packet is transmitted, so that the receiver cannot decode it (120). The receiver generates a couple of public and private keys, and sends back to the transmitter a negative acknowledgment as well as said public key. The transmitter then transmits (130) a second version of the packet, encrypted using said public key. The receiver tries (140) to decode a combination of the first and the second versions of the packet. In case of success, a positive acknowledgment is transmitted to the transmitter and, in case of failure, the retransmission process is iterated.

  • HIERARCHICAL MULTITHREADED PROCESSING
    Publication number: 20110276784
    Abstract: In one embodiment, a current candidate thread is selected from each of multiple first groups of threads using a low granularity selection scheme, where each of the first groups includes multiple threads and first groups are mutually exclusive. A second group of threads is formed comprising the current candidate thread selected from each of the first groups of threads. A current winning thread is selected from the second group of threads using a high granularity selection scheme. An instruction is fetched from a memory based on a fetch address for a next instruction of the current winning thread. The instruction is then dispatched to one of the execution units for execution, whereby execution stalls of the execution units are reduced by fetching instructions based on the low granularity and high granularity selection schemes.

  • Adaptive cell ID detection in a cellular communications system
    Patent number: 8055252
    Abstract: A cell identifier is indicated in a signal to be transmitted in a cellular communication system by selecting one of a number, M, of codes, wherein each of the codes has a length N of code symbols, and wherein the selected code is associated with the cell identifier. The selected code is transmitted as a number, N, of reference symbols. The M codes are orthogonal with one another over their length, N, of the code symbols and also over at least one subgroup of length L of the code symbols, wherein L<M. During cell search, whether to use all N reference symbols or one or more subgroups of the reference symbols to construct one of M possible orthogonal codes depends on what type of cell search is being performed.
