20130171999 | Dynamic Channel Reuse in Multi-Access Communication Systems - Dynamic channel reuse in multi-access communication systems. A first station in a communication network may receive a transmission over a communication medium. The first station may generate a reuse determination based on information from the received transmission. The reuse determination may be usable with at least one other reuse determination to coordinate reuse of the communication medium. | 07-04-2013 |
20140169186 | ADAPTIVE CHANNEL REUSE MECHANISM IN COMMUNICATION NETWORKS - A feature-capable device that supports channel reuse can execute operations for determining whether to reuse or share a communication channel with a neighbor network when a local network (that comprises the feature-capable device) and/or the neighbor network comprise legacy devices that do not support adaptive channel reuse feature. The feature-capable device can determine channel performance measurements associated with each legacy device in the local network and/or the neighbor network and can compare the channel performance measurements against corresponding performance thresholds. The local network and the neighbor network can reuse the channel if the channel performance measurements associated with all the legacy devices are in accordance with the corresponding performance thresholds. The local network and the neighbor network can share the channel if the channel performance measurements of at least one of the legacy devices is not in accordance with the corresponding performance thresholds. | 06-19-2014 |
20140211863 | SWITCHING COMMUNICATION DEVICES BETWEEN DIFFERENT COMMUNICATION MEDIA - A service provider device of a local communication network communicates a first frame with an electric vehicle via a first communication medium to associate with the electric vehicle, establish a communication link with the electric vehicle, and to add the electric vehicle to the local communication network. After an association process between the electric vehicle and the service provider device is successfully completed, the electric vehicle and/or the service provider device can execute operations that extend the utility of their respective communication devices by switching to a new communication medium. By switching to the new communication medium, the electric vehicle and/or the service provider device can connect to a remote communication network. The service provider device communicates a second frame with at least a network device of the remote communication network via the new communication medium. | 07-31-2014 |
20140328416 | SELECTION DIVERSITY IN A POWERLINE COMMUNICATION SYSTEM - A network device can be configured to dynamically adapt its current primary receiver coupling to channel conditions. For each of a plurality of transmitting network devices, the network device can determine a potential primary receiver coupling of the first network device for receiving communications from the transmitting network device based, at least in part, on a performance measurement associated with each of the plurality of communication channels between the network device and the transmitting device. The network device can select its current primary receiver coupling based, at least in part, on the potential primary receiver couplings determined for the plurality of transmitting network devices. In addition, the network device can also determine how to communicate with a receiving network device based, at least in part, on a preferred communication channel between the two network devices and a current primary receiver coupling of the receiving network device. | 11-06-2014 |
20140355621 | CHANNEL ADAPTATION TO COMPENSATE FOR INTERFERENCE FROM NEIGHBOR POWERLINE COMMUNICATION NETWORKS - A first powerline communication device, associated with a first powerline communication network, determines a plurality of time intervals in a beacon period of the first powerline communication network based, at least in part, on variations in levels of interference from a second powerline communication network which shares a powerline communication medium with the first powerline communication network. The first powerline communication device determines at least one channel adaptation parameter for each of the plurality of time intervals in the beacon period to compensate for effects of the variations in the levels of interference from the second powerline communication network. The first powerline communication device applies the at least one channel adaptation parameter corresponding to one or more of the plurality of time intervals in the beacon period when transmitting data via the powerline communication medium. | 12-04-2014 |
20150055563 | ADAPTIVE TRANSMIT POWER CONTROL IN A COMMUNICATION NETWORK - Network devices can be configured to implement adaptive power control functionality in a communication network. A power control requestor of a local communication network can calculate a link margin between a neighbor network device of a neighbor communication network and a local network device associated with a least preferred performance measurement. The power control requestor can transmit a power control message including the link margin to request the neighbor network device to vary the transmit power of the neighbor network device. In response to receiving a power control message, a power control responder can use a link margin indicated in the power control message to evaluate the feasibility of reducing the transmit power of the power control responder. The power control responder can transmit a power control response indicating whether it will vary the transmit power. | 02-26-2015 |
20150078299 | DEFERRAL BASED ON BSSID INFORMATION - Aspects of the present disclosure provide techniques and apparatus for deferral based on basic service set identification (BSSID) information. According to certain aspects, a method for wireless communications is provided. The method generally includes receiving, on a shared access medium, a packet having at least one deferral-related parameter and deciding whether to defer transmission on the shared access medium based, at least in part, on the deferral-related parameter. Another method may generally include generating a packet comprising at least one deferral-related parameter to be used by another apparatus for deciding whether or not the other apparatus should defer transmitting on a shared access medium and providing the packet to the other apparatus. | 03-19-2015 |
20150124744 | WIRELESS COMMUNICATIONS DEFERRAL BASED ON TRANSMISSION OPPORTUNITY - The present application relates generally to wireless communications, and more specifically to systems, methods, and devices for deferral based on transmission opportunity (TXOP) information. One aspect of the present disclosure provides An apparatus configured to wirelessly communicate. The apparatus includes a processing system configured to obtain a deferral-related parameter from a packet transmitted on a shared wireless access medium and decide whether to defer transmission on the shared wireless access medium based, at least in part, on the at least one deferral-related parameter. | 05-07-2015 |
