METHODS OF CONTROL/DATA PARTITION SCHEME IN HETEROGENEOUS NETWORKS FOR LTE-A

摘要

PROBLEM TO BE SOLVED: To coordinate, when there are different power classes of base stations (BSs), transmission from the different BSs to reduce interference with user equipment (UE) on both control channels and data channels.;SOLUTION: A method comprises: identifying subframes that are protected by cooperative partitioning of resources between a serving Node B and one or more non-serving Node Bs 902; transmitting, on a subframe allocated to the serving Node B, a grant message for downlink transmission in a subset of the subframes allocated to the one or more non-serving Node Bs 904; and identifying one or more reference signals, to be transmitted in the subset of the subframes, which are usable by user equipment (UE) 906.;COPYRIGHT: (C)2015,JPO&INPIT
