Abstract: Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations. The UE establishes a RS based measurement according to the subset of the one or more RS resource configurations and an IM according to the subset of the one or more IM resource configurations. The UE then generates and sends to the network a CSI report in accordance with the CSI report configuration and using the RS based measurement and the IM.

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.

Abstract: A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.
