Abstract
Wireless networks may include remote radio heads (RRHs) for extending the coverage of a macro cell. The macro cell may be connected to the RRHs, for example, by optical fiber, and there may be negligible latency between the macro cell and the RRHs. RRH deployment with different cell specific RS transmissions may create many cell edges, which may present challenges in idle state mobility. Certain aspects of the present disclosure may utilize coordinated multipoint (CoMP) transmissions for idle user equipment (UE) support and, in some aspects, may introduce new radio link monitoring (RLM) techniques. As a result, the techniques presented herein may help achieve better idle mode performance and/or better RLM performance.
