Beam Detection, Beam Tracking and Random Access in MM-Wave Small Cells in Heterogeneous Network

摘要

A system and method for beam detection and beam tracking are disclosed. In an embodiment the method includes detecting, by the UE, reference signals sent in beams by one or more small cell nodes, each reference signal being allocated to a beam, measuring, by the UE, beam qualities of the beams, reporting, by the UE, best quality beams to a macro cell node, receiving, by the UE, an assignment from the macro cell node, wherein the assignment is for sending an access signal to the designated small cell node and sending, by the UE, the access signal to the designated small cell node.

1. A method for providing a data link between a designated small cell node and a User Equipment (UE) in a heterogeneous wireless network, the method comprising:
detecting, by the UE, reference signals sent in beams by one or more small cell nodes, each reference signal being allocated to a beam; measuring, by the UE, beam qualities of the beams; reporting, by the UE, best quality beams to a macro cell node; receiving, by the UE, an assignment from the macro cell node, wherein the assignment is for sending an access signal to the designated small cell node; and sending, by the UE, the access signal to the designated small cell node.
