System for efficiently handling cryptographic messages containing nonce values in a wireless connectionless environment without comprising security
A secure communication module that accepts a cryptographic message if a nonce value for the received message is greater than the largest nonce value yet seen. If the received nonce value is not the largest nonce value yet seen, the secure communication module compares the received nonce value with a nonce acceptance window. If the nonce value falls outside the nonce acceptance window, the secure communication module rejects the received message and assumes a replay attack. Alternatively, if the nonce value falls within the nonce acceptance window, the secure communication module compares the received nonce value with a replay window mask. If comparison with the replay window mask indicates that the received nonce value has been seen before, the secure communication module rejects the received message and assumes a replay attack. Otherwise, the secure communication module accepts the message and adds the received nonce value to the replay window mask. |

Coding schemes for wireless communication transmissions
Systems and methodologies are described that facilitate transmitting low-density parity-check encoded communications in a wireless communications network and incrementing such codes in response to requests from receiving devices. The LDPC codes can have associated constraints allowing the codes to be error corrected upon receipt.

In this case, additional nodes can be added to current and/or subsequent communications to facilitate adding a more complex constraint to the LDPC code. In this regard, the large codes can require less validly transmitted nodes to predict error-ridden values as the additional constraint renders less ambiguity in possible node value choices. |

A range of values on a normalized scale is determined for an option for an attribute associated with a representative item. The range of values of the representative item is correlated with a first unit on a first scale of item classification. Multiple items are identified based at least in part on the option for the attribute. Each of the items is associated with a respective option for the attribute that has a respective range of values on the normalized scale that overlaps the range of values of the representative item. The respective range of values of one or more of the items is correlated with a second unit on a second scale of item classification. |

Control signal aggregation in a multi-carrier WCDMA system
Methods and apparatus are disclosed for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal. In an exemplary method, aggregated control channel data is formed by combining control channel data corresponding to each of two or more received carrier signals, simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels, and transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals. In particular, these methods and apparatus may be applied to a multi-carrier High-Speed Packet Access (HSPA) system. |

Wireless network with contention and contention-free periods
A wireless network (1) comprises mesh devices and non-mesh devices. A medium access control architecture incorporates at least a point coordination function as an access method, wherein the point coordination function starts a contention-free period (30) with a beacon (32) so that a non-polled transmission by the non-mesh devices is prevented. Further, the mesh devices are enable to communicate during the contention-free period (30). Hence, communication between the mesh devices is priorisized so that a high reliability is achieved and utilization of the wireless network (1) is optimized. |

Apparatus and method for supporting frequency rearrangement in wireless communication system
A base station includes a center frequency setting unit, a local oscillator, a baseband processor, and an RF processor. In the event of a frequency band change, the center frequency setting unit sets a center frequency of a use frequency channel to have a predetermined offset value with respect to a center frequency before the frequency band change. The local oscillator generates an LO frequency signal according to the center frequency set by the center frequency setting unit. The baseband processor generates a downlink baseband signal. The RF processor uses the LO frequency signal to convert the downlink baseband signal into an RF signal prior to transmission. |
