Embodiment Construction

[0020] Reference will now be made to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0021] In the LTE system, two radio resource control (Radio Resource Control, RRC) states are defined, namely RRC_IDLE and RRC_CONNECTED states. In the RRC_IDLE state, the UE may receive broadcast or multicast data, monitor call channels to detect incoming calls, perform neighbor cell measurements for cell selection / reselection, and acquire system information broadcast (MIB / SIB). In the RRC_IDLE state, mobility functions are fully controlled by the UE. In the RRC_CONNECTED state, transmission of unicast data from / to the UE and transmission of broadcast / multicast data to the UE may occur. The UE monitors control channels corresponding to common data channels to determine scheduled data, provide channel quality feedback information, perform neighbor cell measurements and report measurements, and obtain MIB / SIB updates. Unlike the RRC_IDLE st...

Abstract

The invention provides a method of user equipment (UE) measurements and network access procedure of interference coordination, wherein the method of UE measurements of interference coordination comprises: receiving a plurality of radio signals of a cell under measurement by the UE in a wireless communication system, wherein the UE is in idle mode; detecting a plurality of interfered radio resources by the UE for interference coordination, wherein the UE receives a plurality of strong interfering signals from a non-accessible neighboring cell; and determining a plurality of restricted radio resources by excluding the plurality of interfered radio resources from the plurality of radio resources of the wireless communication system. The method of UE measurements of interference coordination provided by the invention can increase radio spectrum efficiency and improve user experience.

Description

[0001] Cross References to Related Applications [0002] The claims of this application claim priority under 35 U.S.C. §119 to the following application: US Provisional Application No. 61 / 411,052, filed November 8, 2010, entitled "Method of UE pattern indication in Heterogeneous Network"; 2010 Application No. 61 / 411,539, filed November 9, 2009, entitled "Method for Static interference Coordination," US provisional case. The entire contents of the aforementioned application are hereby incorporated by reference. technical field [0003] The present invention relates to wireless network communication, and more particularly to user equipment (UE) pattern indication and measurement for inter-cell interference coordination (ICIC). Background technique [0004] ICIC was introduced in Release 8 / 9 of the 3GPP LTE standard. The basic concept of ICIC is to keep inter-cell interference under control through a radio resource management (RRM) method. ICIC is essentially a multi-cell R...
