  • Patent number: 10805928
    Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.

  • Publication number: 20200322108
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.
