Mobility management in ultra dense networks

摘要

User equipment (UE) mobility in a super dense network (UDN) may include, for example, orthogonal frequency division multiplexing (OFDM) domains, code domains using separate codebooks, and / Based on the communication signal layer. The UE uses a candidate layer decoding parameter when applying layer-based decoding to communication signals received from a network node. As the UE moves between different network service areas, a layer may be assigned to the UE and switched between network nodes. Alternatively, a layer may be assigned to the network node. Hierarchical based decoding provides UE mobility without requiring explicit handover processing whenever the UE moves between different service areas.
