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: Notifying served user equipments (UEs) of the presence or absence of cell-specific reference signal (CRS) symbols transmitted by neighboring base stations in the physical downlink shared channel (PDSCH) region of a subframe can be achieved through various of signaling techniques. The served UE may be notified by communicating a one or multi-bit indicator in a physical layer signaling channel of the serving cell, such as the physical downlink control channel (PDCCH) of the subframe. Alternatively, the served UE may be notified through higher layer signaling.

Abstract: The disclosure relates to a base station configuring component carriers to user equipment (UE). The base station determines one or more component carriers to configure based on the UE carrier aggregation capability and sends a first configuration signaling to configure the UE with the component carriers in one or more component carrier sets. The base station configures each of the component carrier sets with a first common parameters and operations set and sends a second configuration signaling to configure the component carrier sets of the UE with the first common parameters and operations set. The base station then sends a third configuration signaling to configure each of the component carriers in the UE with a second parameters and operations set.
