  • Patent number: 10993213
    Abstract: The invention provides a method and an apparatus for controlling secondary carriers in an asymmetric uplink carrier aggregation, the method includes: an eNB transmits configuration information of uplink secondary carriers configured for a UE to the UE, wherein the configuration information includes carrier-specific common configuration information and/or UE-specific configuration information; furthermore, the eNB schedules the uplink secondary carriers via a physical downlink control channel PDCCH of the downlink primary carrier, so that the UE performs a scheduling of a PUSCH to the eNB via the uplink secondary carriers, thus realizing a control of the secondary carriers in the asymmetric uplink carrier aggregation and greatly improving the uplink throughput.

  • Patent number: 8565215
    Abstract: A method and a base station can be used for detecting an interfering base station. A second base station sends no second downlink synchronization code in a downlink pilot time slot DwPTS of a specified frame, so that the second base station receives a first downlink synchronization code in a downlink pilot time slot DwPTS of a first base station, and performs correlation calculation on a detecting code segment of uplink data of the second base station by using the first downlink synchronization code, and by judging whether a correlation value of one of detecting code segments in the uplink data is greater than a correlation value threshold, determines whether the second base station is an interfering base station of the first base station.
