Document Type and Number:
WIPO Patent Application WO/2012/137077
Kind Code:
A8
Abstract:
The present invention proposes a method, in an eNB in wireless communication network based on carrier aggregation (CA) transmission, for controlling random access performed by UE, wherein the method comprises: determining whether the UE is out of UL sync on all cells, wherein the cells comprises Pcell and Scell: sending Physical Downlink Control Channel (PDCCH) order signaling if the UE is out of UL sync on all the cells, wherein the PDCCH order signaling is used to indicating the UE to perform random access. A method, in a mobile station in wireless communication network based on carrier aggregation (CA) transmission, for random access, wherein the mobile station is configured a Pcell and at least one Scell, and the method comprises: determining whether random access is needed on at least one cell of the cells, wherein the cells comprises the Pcell and the at least one Scell; performing random access on at least one cell of all the cells, if it is determined that random access is needed on at least one cell of the cells.
