  • Patent number: 10819627
    Abstract: A method and device for realizing automatic stacking of network devices are disclosed. According to an example of the method, when a network device determines its device role, the network device may send a first neighbor discovery message to a neighbor device and receive a second neighbor discovery message sent by the neighbor device. Next, if it determines that a topological structure between the network device and the neighbor device changes according to the second neighbor discovery message, the network device may determine whether a stacking condition to trigger stacking the network device and the neighbor device is satisfied or not. If the stacking condition is satisfied, the network device may further determine a stacking configuration for stacking the network device and the neighbor device. Then the network device may stack the network device with the neighbor device according to the stacking configuration.

  • Patent number: 10798735
    Abstract: Solutions to problems from delays in channel acquisition by UEs in a contention-based shared radio frequency spectrum band are disclosed. For example, if an eNB knows of a recent or ongoing downlink transmission on a frequency to be used for uplink transmission by a UE, then the eNB may instruct the UE to either skip performance of LBT on that frequency or else perform a type of LBT that is shorter in duration than a full CCA. One way for the eNB to instruct the UE in this fashion is to set an indicator in an uplink grant transmitted to the UE on another frequency. Additionally, in order to avoid truncation of an uplink transmission opportunity, an eNB may notify a UE that an uplink grant is valid for more than one starting point.

  • Patent number: 10728011
    Abstract: This invention relates to the proposal of component carrier (de)activation message that is allowing a activation or deactivation of one or more component carriers in the uplink or downlink. Furthermore, the invention relates to the use of the new component carrier (de)activation message in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, the invention proposes to use component carrier-specific or cell-RNTI(s) for the scrambling of the CRC of the component carrier (de)activation message, and to explicitly indicate the intended recipient of the component carrier (de)activation message in a corresponding field in the message. Furthermore, the invention further proposes different designs of the component carrier (de)activation message and further uses thereof, so as to trigger CQI reporting and/or SRS transmission by a mobile terminal.

The CSI process configuration information includes at least one CSI process, and a first CSI process in the at least one CSI process is associated with K reference signal resources and M interference measurement resources. For the first CSI process, the receive end obtains a target reference signal resource based on the K reference signal resources, obtains a target interference measurement resource based on the M interference measurement resources, and obtains CSI based on the target reference signal resource and the target interference measurement resource. The receive end sends the CSI. The CSI includes a target index, and the target index is used to represent the target reference signal resource and/or the target interference measurement resource. In this way, CSI feedback flexibility is improved.
