摘要： In a wireless communications system, a serving base station performs outer and closed power control for an overhead channel and a traffic channel for data, either of which can carry an acknowledgement (Ack) channel and Channel Quality Indicator (CQI) channel on an uplink from User Equipment (UE). In an exemplary aspect, data packet communication is implemented in 3GPP LTE Rel. 8 wherein the uplink has a Single Carrier Frequency Division Multiplex (SC-FDM) uplink waveform. The UE performs open loop power control by a determining transmit power spectral density value by using received energy per symbol for a reference signal.

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： Some implementations of the present invention provide mechanisms for gating the transmission of FIN and other short overhead messages of the like in order to improve spectral efficiency. In some implementations spectral efficiency is improved by reducing the number of air-link connections established to merely transmit FIN and other short overhead messages of the like. In one implementation FIN messages are buffered in a queue and transmitted when an air-link connection is established to transmit higher value messages. In one implementation FIN messages are buffered and transmitted when the contents of the buffer breach a threshold that justifies the establishment of an air-link connection to transmit the contents of the buffer.
