    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： Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths, and transmitting packets based on the determined weights. In one implementation, the method includes sorting packets at least according to one of size, type and nature of the data in the packets. Accordingly, sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation, sorting the packets includes deep-packet inspection to determine a respective priority value for each packet.

    摘要： Techniques for managing communications in a cellular network are disclosed. The cellular network can include one or more sectors in which hotspot carriers are deployed. The hotspot carriers can be available to mobile devices beyond sector boundaries defined by the signal strength of ubiquitous carriers. A mobile device can measure a signal strength of a candidate hotspot carrier and estimate a reverse link mobile device transmit power level for communicating on the hotspot carrier. The mobile device may determine whether to add, remove, or maintain the hotspot carrier in its active set based on the estimated transmit power level so as to limit interference to the reverse link of non-hotspot sectors.

    摘要： Allocating transmit power among two or more carriers assigned to a wireless communication device is disclosed. In one aspect, a method of allocating transmit power includes determining a total amount of data transmit power available at the wireless communication device for data transmission over the carriers. An efficiency metric is determined for each carrier based on the carrier's transmission characteristics and a portion of the total data transmit power is allocated to each carrier based on each carrier's efficiency metric.
