Abstract

The invention discloses a self-adapted inter-cell interference coordination method based on a cell candidate PCC. The method includes the following steps: firstly, defining a component carrier of a sending user PDCCH to be the PCC and a component carrier of a sending user PDSCH to be an SCC, and then performing self-adapted inter-cell interference coordination based on cell candidate PCC self-optimizing and self-adapted inter-cell interference coordination based on cell candidate PCC self-optimizing. On the premise of guaranteeing the overall spectral efficiency of macro+pico, the user PDCCHSINR and the PDSCH SINR of a pico cell are improved, and edge user throughput and cell throughput have large gain; the user PDCCH SINR of a macrocell is improved. The strengthened inter-cell interference coordination method based on the cell candidate PCC self-optimizing can self-adapt to the deployment location and the user distribution of pico eNB, and therefore the downlink interference of the macrocell between the pico cells is effectively reduced.

Description

technical field [0001] The invention relates to an adaptive inter-cell interference coordination method based on self-optimization of cell candidate main component carriers in a heterogeneous cellular network, and belongs to the network technology field in mobile communication. Background technique [0002] Heterogeneous cellular networks bring low-power nodes (such as home base stations (HeNB), pico base stations (pico eNB), relays, etc.) Cell splitting gain greatly improves cell throughput and average user throughput. For the geographical coverage of the entire macro cell, the heterogeneous cellular network adds a lot of cell boundaries; on the other hand, due to the flexibility of the deployment location and number of low-power nodes, it leads to irregular and overlapping coverage of the low-power node coverage area . Therefore, low-power nodes will face both cross-layer interference from nearby macro stations and same-layer interference from nearby low-power nodes. Si...
