    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: System and method embodiments are provided for network adaption and utilization of a discovery signal (DS). In an embodiment, a method in a UE for communicating in a wireless network includes receiving a parameter(s) from a network controller, wherein the parameter provides the UE with an activation time frame within which the UE can expect to receive a common reference signal (CRS) from a network component, a deactivation time frame within which the UE is not to expect to receive the CRS, and information for receiving and processing a DS from the network component; receiving the DS from the network component, wherein a structure and format of the DS conforms to the parameter received by the UE; refraining from attempting to perform CRS based procedures when the CRS is not received; and performing one of synchronization, cell identification, and DS based radio resource management (RRM) measurements according to the DS.

    Abstract: A network controller may configure one or more channel state information-reference signal (CSI-RS) configurations for transmitting RSs to user equipments (UEs) for tracking. A CSI-RS configuration may specify a set of CSI-RS resources for transmitting RSs in two consecutive slots. The set of CSI-RS resources may include a plurality of one-port CSI-RS resources configured according to the CSI-RS configuration. The CSI-RS configuration may specify a quasi co-location (QCL) configuration including a set of QCL parameters, where a demodulation reference signal (DMRS) has a QCL relationship with the RS with respect to the set of QCL parameters. The network controller may signal the one or more CSI-RS configurations to UEs.
