    摘要: Remote units within a first communication system (121) utilizes frequencies (channels) from a second communication system (120) when placing a call. When a first remote unit (106) wants to call a second remote unit (107) using the channels, the first remote unit sends a base station (103) a list of top N traffic channel blocks from the second communication system along with the identity of the second remote unit. The base station then pages the second remote unit using a signaling channel reserved by second system. The second remote unit responds to the page with its list of best traffic channel blocks/chunks. The base station then picks the best overlap of idle channels from the list received by the remote units, and sends the list to the remote units instructing them use those traffic channels. Once the remote units receive the available channels, they can begin their call.

    摘要: Nodes (103a-d, 105, 107, 109a-c, 111a-c) in an ad hoc communication network are coordinated. The network includes the node (111b) and one or more neighbor nodes (103a-d, 105, 107, 109a-c, 111a,c). The node (111b) can sleep in a low duty cycle. Further, the node (111b) can awaken, responsive to a schedule; and register with a cluster head (101); listen for one or more neighbors, wherein the at least one neighbor can be active (103a-d, 105, 107) or idle (109a-c, 111a,c); and/or listen for one or more requests from the cluster head (101) or active neighbor(s) (103a-d, 105, 107). Responsive to the request(s), the idle node (111b) can become active on a communication link.

    摘要: A method and apparatus for electing broadcast relay nodes (520B, H, M) in an ad hoc network (500). Each node (520A-520O) generates an attribute message including associated parameters. Each node (520A-520O) generates a weighted value (WV) based on the parameters. The WV can be included in the attribute message for that node, can provide a metric for ranking that node to be nominated to be a broadcast relay node, can alternatively provide a probability measure for that node to probabilistically elect itself as a broadcast relay node. The broadcast manager node (520C) receives the attribute messages and elects at least one nominated node as a broadcast relay node (520B, H, M) based on the attribute messages. Each node (520A-520O) can also initiate election of an intermediate broadcast relay node if that node fails to receive a test message within a predetermined time.

    摘要: An etiquette controller (112) in a transmitter (14) in a first radio frequency (RF) communications system (10) enables radio frequency communications in a frequency bandwidth shared with heterogeneous RF communication systems (15). The etiquette controller (112) monitors the first RF signals in an isochronous frequency channel in a sub-band of the shared frequency bandwidth to determine whether (124) a frequency channel is free or whether (130, 136) the frequency channel comprises a communication channel which is free. In addition, the etiquette controller (112) causes the RF transceiver (102) to transmit (148) a channel relinquishment signal, monitors (150) the isochronous frequency channel for a predetermined monitoring time, and determines (152) whether the isochronous frequency channel is then free for the channel access.

    摘要: Techniques are provided for allowing a node (300) in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node (300) receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node (300) may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node (300) can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node (300) may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.

    摘要: A technique is used in a data terminal (110, 160) that encodes and decodes a data packet that is transmitted in a link of a frequency hopping system. During encoding, an information portion of the data packet is determined for transmission, a transmit redundancy check code is generated over the information portion and an identifier using a predetermined redundancy check code generator, and the data packet is generated to include the transmit redundancy check code and the information portion, but exclude the identifier. During decoding, the information portion and a received redundancy check code of the received data packet are determined, a calculated redundancy check code is generated over the information portion and the identifier, using the predetermined redundancy check code generator, and the information portion is rejected when the received redundancy check code does not match the calculated redundancy check code.

    摘要: A two-way communication system is used for performing dynamic channel control. The two-way communication system comprises a base transceiver (102) and a plurality of selective call transceivers (122). The base transceiver (102) includes a plurality of base stations (116) controlled by a controller (112). The base transceiver (102) transmits query signals to the selective call transceivers (122) to prompt communication. The selective call transceivers (122) measure the signal quality of signals transmitted by the two-way communication system and transmit in return signal quality measurement data to the base transceiver (102) for analysis. The base transceiver (102) dynamically adjusts the signal quality of signals to be received by the selective call transceivers (122) in order to substantially reduce the noise interference that the selective call transceivers (122) experience.

    摘要: A communication system is designed that reduces co-channel interference when heterogeneous users are sharing spectrum. The system design enables a plurality of pairs of users to communicate their channel utilization time periods by using the durations and start or stop times of certain transmissions to signal the start times and durations of later transmissions. Other system users using possibly different communications protocols and different modulation technologies can measure the durations of received transmissions and to infer channel usage based on these durations.
