| 20100246434 | NETWORK ENTRY AND DEVICE DISCOVERY FOR COGNITIVE RADIO NETWORKS | 09-30-2010 |
| 20100246442 | DISTRIBUTED SCHEDULING OF QUIET-PERIOD FOR IN-SERVICE CHANNEL MONITORING - In a distributed-control cognitive radio network, each secondary user ( | 09-30-2010 |
| 20100260085 | FLEXIBLE MAC SUPERFRAME STRUCTURE AND BEACONING METHOD - A flexible wireless system and method that support both centralized and distributed modes of MAC protocols, use a new recurring MAC superframe (m) comprising: a beacon period (BP), a data/sense/sleep period (DSSP) for data selective communication, sleep and channel sensing for detecting primary users in cognitive systems; and a signaling window (SW) used for exchanging network entry messages and channel reservation requests, the system including beacon operation, a peer beacon device in distributed mode and a master beacon device in centralized mode which are used to selectively participate in the beacon operation, as well as a slave beacon device associated with the master device. The system may employ controlled channel access for the beacon period, the channel access being reservation based. The invention provides a unified MAC protocol that can be adopted in the standards, and supports flexible operation in distributed mode or centralized mode, and seamless transfer from one to the other. | 10-14-2010 |
| 20100271948 | CHANNEL MANAGEMENT METHOD IN A DISTRIBUTED SPECTRUM COGNITIVE RADIO NETWORK - A source-assisted channel management method in a distributed spectrum cognitive radio wireless network handling a source of multimedia stream data handles a plurality of communicating devices ( | 10-28-2010 |
| 20100284340 | METHOD OF PACKET RETRANSMISSION AND RECEPTION AND WIRELESS DEVICE EMPLOYING THE SAME - A first wireless device communicates data to a second wireless device. The first wireless device employs at least one of a first interleaving scheme and a first sub-carrier mapping scheme to produce a first data packet from a first plurality of data bits, and transmits the first data packet to the second wireless device. When the first data packet is not received correctly by the second wireless device, then the first wireless device employs at least one of a second interleaving scheme and a second sub-carrier mapping scheme to create a second data packet from the first plurality of data bits, and transmits the second data packet to the second wireless device. | 11-11-2010 |
| 20100304772 | MULTIPLE CHANNEL SUPPORT IN DISTRIBUTED WIRELESS SYSTEMS - To facilitate multi-channel communications over distributed-control radio networks, the timing of networks on multiple substantially independent channels are adjusted ( | 12-02-2010 |
| 20110255500 | SELF-COEXISTENCE OF DEVICES IN A FLEXIBLE WIRELESS SYSTEM INCLUDING TWO OR MORE WIRELESS NETWORKS THAT SHARE A FREQUENCY BAND | 10-20-2011 |
| 20110261793 | CHANNEL RESERVATION IN FLEXIBLE WIRELESS NETWORKS - Channel access time slots are reserved in a wireless network employing a flexible medium access control (MAC) protocol. At least a type and a mode of the channel reservation are determined (S | 10-27-2011 |
