摘要： A controller in a wireless communication system includes a transceiver to receive channel activity reports from a first node and a plurality of second nodes that are connected to the first node. The first node supports wireless communication over one or more first channels of a licensed frequency band and second channels of an unlicensed frequency band. The second node supports wireless communication over the second channels of the unlicensed frequency band. The controller also includes a processor to allocate a subset of the second channels to the first node and the plurality of second nodes based on the channel activity reports.

摘要： A technique for reducing interference in a GPS-equipped wireless device having a transmitter is provided. In doing so, a GPS signal is acquired, and it is determined whether the GPS signal contains valid GPS data, the GPS signal having a GPS frequency range. If the GPS data is not valid due to the noted second harmonic interference, the transmit power levels of the transmitter within different categories of frequency blocks (frequency blocks corresponding to the second harmonic of the transmit frequency of the device interfering with the GPS frequency range entirely, partially and only slightly) are selectively and iteratively determined. The power levels in these frequency blocks are iteratively and selectively reduced to help determine valid GPS data.

摘要： A base station receives packets at a base station in a first network that operates according to a first radio access technology (RAT). The base station selectively routes a portion of the packets towards one or more second networks that operates according to one or more second RATs and transmits information indicating a number of packets in the portion of the packets. The gateway receives the information indicating the number of packets from the base station, determines charging information based on the information indicating the number of packets, and transmits the charging information to a charging entity in the first network.

摘要： Successfully decoded data received from a mobile terminal as well as the transmission format of that data is relayed over the backhaul from a base station receiver that successfully decoded the mobile terminal's transmission to the base stations in the mobile terminal's active set that presumably were unable to decode the mobile terminal's transmission due to inadequate signal-to-noise ratio. A base station that receives this transmission from the relaying base station that did successfully decode and demodulate the mobile terminal's transmission is then able to reconstruct the data and subtract it from the total interference, thereby increasing the signal-to-noise ratio at this base station for its in-cell processing.

摘要： In a wireless telecommunications network, there is included: a macro cell (10) having a first coverage area; and at least one metro cell (20a, 20b, 20c) having a second coverage area, the metro cell being located within the first coverage area of the macro cell. Suitably, the macro cell is configured to: determine whether or not the macro cell is congested; determine whether or not the metro cell is uncongested; and, if it is determined the macro cell is congested and that the metro cell is uncongested, then the macro cell determines that an attempted application of Cell Association Bias (CAB) for the metro cell is warranted. Suitably, if CAB is in fact applied, the macro cell also implements enhanced Inter Cell Interference Coordination (eICIC) using Almost Blank Subframes (ABS) and informs its other neighboring metro cells of this configuration.
