Abstract: A method is provided to associate at least one user equipment to a plurality of component carriers. A carrier-to-interference ratio is calculated for each of component carriers available for the user equipment. Differences between the calculated carrier-to-interference ratios are calculated, with each difference being associated to a different one of the component carriers intervening in the difference, the component carriers being ordered in the decreasing order of their carrier frequency. The user equipment is associated with the component carrier having the lowest difference.

Abstract: A controller implemented on computing equipment may control switches in a network. The controller may provide flow tables that implement network policies to the switches to control packet forwarding through the network. The controller may provide debug table entries to the switches for use in a debug table that is separate from the flow table. The debug table entries may match incoming network packets and increment corresponding counters on the switches. The controller may retrieve count information from the counters for performing debugging operations on the network. For example, the controller may identify conflicts between fields of a selected flow table entry, determine whether elephant packet flows are present between switches, determine whether desired load balancing is being performed, determine whether a network path has changed, determine whether packet loss has occurred, and/or determine whether network packets are taking undesired paths based on the retrieved count information.

Abstract: First data may be transmitted during a first timeslot of a transmission time period using a first wireless communication standard and second data may be transmitted during a second timeslot of the transmission time period using a second wireless communication standard. Based on change(s) to one or more characteristics associated with data transmitted using the first wireless communication standard, such as a change in the wireless profile or wireless protocol being used, a duration of the transmission time period may be adaptively increased and/or a duration of the first timeslot may be adaptively decreased. In either scenario, a duration of the second timeslot may increase. This increase in the duration of the second timeslot may result in an increase in a frame aggregation count associated with the second wireless communication standard, allowing more data frames to be aggregated into a single packet, thereby increasing packet length and data throughput.

Abstract: The present disclosure describes methods and apparatus for synchronizing devices in a wireless data communication system. A wireless transceiver device of the wireless data communication system transmits a beacon at various intervals that includes both a timestamp indicating a current time and date of the transmitting wireless transceiver device, and a time quality indication indicating a quality of the time source of the transmitting wireless transceiver device. A wireless transceiver device receiving the beacon evaluates the time quality indication included in the beacon. If the time quality indication included in the beacon indicates the transmitting wireless transceiver device has a higher quality time source than the receiving wireless transceiver device, then the receiving wireless transceiver device adjusts its clock based on the timestamp in the beacon, otherwise the receiving wireless transceiver device need not adjust its clock based on the timestamp in the beacon.
