Abstract: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology (“RAT”) to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.

Abstract: A system and method for configuring component carriers in carrier aggregation is disclosed. The method comprises communicating a carrier aggregation capability for a selected UE to an enhanced Node B (eNode B) configured to provide service for a plurality of UEs. A plurality of component carriers at the eNode B can be configured for the selected UE based on the carrier aggregation capability of the selected UE. A component carrier configuration message is broadcast from the eNode B containing component carrier configuration information that is common to the plurality of UEs. Specific configuration information that is specific to the selected UE is communicated using dedicated communication signaling. Selected configured component carriers are then activated by the eNode B for the selected UE. Activation can be based on the UE's quality of service needs, bandwidth needs, and strength of signal for the component carriers.

A downlink transmission point can be selected based on the UE signal. The UE can then be configured to report CSI-RS measurements for the selected downlink transmission point.

Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (UE) experiences enhanced signal reception and/or reduced interference.

This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.
