Radio Link Montoring Measurements on Restricted Subframes in Heterogeneous LTE-Advahced System
The user equipments (UE) shall monitor the downlink radio link quality, which depends on- physical downlink control channel (PDCCH) block error rate (BLER), and provides feedback to the eNodeB. In heterogeneous networks, since a number of low power nodes are overlaid by a Macro cell and the unbalanced transmitting power are provided between different cell layers, the control channels would suffer more serious interference than in the case of homogeneous networks. Release 8/9 inter-cell interference coordination (1CIC) techniques are not fully effective in mitigating control channel interference. This paper gives a time domain solution for ICIC and presents link level simulations on the radio link monitoring (RLM) performance for legacy Release 8/9 terminals in the case Macro eNodeB interference, and propose that the sufferable interference level for RLM performance.
