Abstract: Carrier aggregation and dual connectivity leverage multiple component carriers to increase the effective bandwidth available to a given UE. Embodiments of this disclosure extend the concept of carrier aggregation and dual connectivity by using a physical component carrier and one or more virtual component carriers from one physical component carrier group and/or one virtual component carrier group, which have the same carrier frequency and carrier bandwidth as the physical component carrier, to transmit data streams to a user equipment. Data streams communicated over the physical component carrier and the virtual component carrier(s) may be orthogonal in the time domain or code domain. Alternatively, data streams communicated over the physical component carrier and the virtual component carrier(s) may be non-orthogonal, in which case the UE may need to decode the respective data streams using non-orthogonal signal processing techniques.

Abstract: Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.
