METHOD AND APPARATUS FOR CELL SELECTION AND HANDOVER IN LTE-ADVANCED HETEROGENEOUS NETWORKS

摘要

PROBLEM TO BE SOLVED: To avoid frequent cell selection/reselection and handover in an LTE-advanced heterogeneous network by utilizing systems and methods based on PBCH muting.SOLUTION: A pico eNB that is fully covered by a macro eNB or other pico eNBs transmits a blank PBCH such that it is inaccessible to the UEs that perform cell selection/reselection. Furthermore, a macro eNB may handover a UE to the inaccessible pico eNB by signalling the necessary information to the UE to detect the inaccessible pico eNB. Frequent cell selection/reselection and handover may therefore be avoided in a dense network.
