摘要
A method of radio link monitoring (RLM) and radio link failure (RLF) handling over a small cell network is proposed. In a wireless network, a user equipment (UE) establishes a radio resource control (RRC) connection with a base station (eNB), which is UE anchor. The UE applies carrier aggregation for multiple component carriers (CCs) configured as multiple serving cells. The aggregated serving cells are served by the anchor eNB and other drift eNB(s). The UE performs RLM/RLF over PCELL and SCELL belonging to corresponding cell groups. When RLF happens in a serving cell, the UE and the eNB apply certain actions over the serving cell or all serving cells in the group. RLF procedures in anchor eNB and in drift eNB are proposed. Both UE side and network side behaviors are included.
