Apparatus, method and system for uplink control channel reception in heterogeneous wireless communication networks

摘要

System and method for improving the reception of the uplink transmission in a heterogeneous wireless communication system includes a high power nodes such as macrocell, and a low power nodes such as picocells, or femtocells. To close the low power node to power control the UE, receiving the uplink transmission of HSDPA control channel in the result serving cell becomes insufficient, and to deal with uplink imbalance, RNC is the uplink transmission to the UE It can disable power control of a UE according to the low power node or instruction to increase the power, or to exclude from the UE soft handover. In order to address the inter-cell interference, RNC can allow that the cells of the sacrificial / or to suppress interference and to limit the transmit power of the UE. In addition, common control channel may be used to power control the UE outside of the conventional UE sets available for power control. [Selection Figure 13
