摘要： A method of regulating data flow in a wireless communication network includes: collecting data regarding dynamic loading of sector-carrier pairs (pilots) in communication sectors of the wireless communication network; obtaining data rates for data flows of the pilots to access terminals within the wireless communication network; determining one or more pilots to use for conveying data in the wireless communication network based on the data rates and the dynamic loading; and altering data flow over the pilots by at least one of changing a data rate over at least one of the pilots or changing a combination of pilots used by the wireless communication network for conveying data to increase total data flow.

摘要： Carrier management in a wireless communication device assigned a set of two or more carriers by a wireless communication network is disclosed. In one aspect, a method of carrier management includes transmitting data over the wireless communication network on one or more carriers forming a subset of active carriers from the set of carriers assigned to the wireless communication device. A first performance metric is determined indicative of operating conditions across the set of carriers assigned to the wireless communication device. A desired number of carriers on which to transmit data based on the first performance metric is determined. The desired number of carriers on which to transmit data is compared with the number of carriers in the subset of active carriers. The subset of active carriers is dynamically adjusted based on the comparison and subsequent data is transmitted over the wireless communication network using the adjusted subset of active carriers.

摘要： Techniques for the reuse of airlink resources in a cellular network are disclosed. A base station controller may gather information about load levels at adjacent sectors of the cellular network. The base station controller may generate and distribute a reuse reference to base stations serving mobile devices in the adjacent sectors. Alternatively, the base station controller may provide the load level information to base stations serving the adjacent sectors and the base stations may determine a sector reuse pattern. The reuse reference or reuse pattern may be adapted to sector load conditions and may designate any combination of carriers, time slots, and power levels for data transmission in a sector. The base stations may schedule data transmission to mobile devices in their respective sectors according to the reuse reference or reuse pattern. The base stations may modify their resource usage in response to changes in sector load.

摘要： A method of wireless communication includes periodically adjusting a target queue length based on an estimated throughput of a network link and based on a measured underflow on the network link. The target queue length represents an amount of data being buffered at a network element. The method also includes controlling a link throughput based on the target queue length.
