| 20110299612 | UNCONTROLLED SPATIAL MULTIPLE ACCESS IN WIRELESS NETWORKS - An uncontrolled spatial multiple access system and method facilitating spatial multiple access for multiple devices in a wireless local-area network (WLAN). Embodiments of the system and method increase throughput of the wireless network by facilitating concurrent encoded frame transmission. Decoding of the quasi-overlapped frames is achieved using a chain decoding technique that takes data streams (or signals) containing the quasi-overlapping encoded frames and isolates each encoded frame so that the frame can be decoded. Quasi-overlapped frames means that the frames are overlapped in the body of the frame but not at the preamble (or headers) of the frames. Embodiments of the chain decoding also use interference nullifying and interference cancelation to enable concurrent quasi-overlapping transmission. A carrier counting multiple access technique of embodiments of the system and method allow wireless networks to retain their asynchronous nature while supporting spatial multiple access and maintain backwards compatibility with the IEEE 802.11 standard. | 12-08-2011 |
| 20110317633 | FINE-GRAINED CHANNEL ACCESS IN WIRELESS NETWORKS - A fine-grained channel access system and method to facilitate fine-grained channel access in a high-data rate wide-band wireless local-area network (WLAN). Embodiments of the system and method divide an entire wireless channel into proper size subchannels commensurate with the physical layer data rate and typical frame size. Once the subchannels are defined, each node on the WLAN contends independently for each of the fine-grained subchannels. A first orthogonal frequency-division multiplexing (OFDM) technique is used to signal an access point on the WLAN that the node desires one or more of the subchannels. A second OFDM technique (which is different from the first OFDM technique) is used for data transmission. Sometimes there is contention between nodes that want the same subchannel. The access point resolves any contention between the nodes using a frequency domain contention technique that includes a frequency domain backoff technique. | 12-29-2011 |

| 20100132028 | METHOD FOR IMPLEMENTING SECURITY-RELATED PROCESSING ON PACKET AND NETWORK SECURITY DEVICE - Embodiments of the present invention provide method for implementing security-related processing on packet and a network security device. Through establishing a relationship between stream attribute information of an initial packet of a stream and security-related processing information implemented on the initial packet, when a succeeding packet of the stream is received, the previously stored relationship is acquired according to stream attribute information of the succeeding packet, the security-related processing is implemented on the succeeding packet according to the security-related processing information in the relationship. Therefore, according to the method for implementing security-related processing on packet and the network security device provided by the present invention, the process of searching for security information entries for succeeding packets of a stream is not required, the security-related processing procedure of the packet is thus accelerated, and the packet processing efficiency is improved. | 05-27-2010 |
