摘要:
A method of informing a selected CN operator from a UE to a RAN in an NS system where a plurality of CN operators shares the RAN is provided. Upon request of transmission of an IDT, the UE acquires a CN operator ID selected from a multi-ID list broadcasted from a cell in which an RRC connection has been established, and transmits an IDT message with the selected CN operator ID to the RAN. Upon receipt of the IDT message, the RAN determines whether the IDT message includes a selected CN operator ID. In the presence of the selected CN operator ID, the RAN stores the selected CN operator ID in a UE context. In the absence of the selected CN operator ID, the RAN reads a stored selected CN operator ID from the UE context. The RAN then selects a CN operator using the selected CN operator ID.

A method and system for relocating a SRNC in a RAN in an NS system where the RAN is shared among a plurality of CN operators are provided. If an SRNC relocation from a source RNC to a target RNC is determined for a UE, the source RNC requests to the target RNC a PLMN list with the PLMN ids of CN operators sharing the target RNC, and receives the PLMN list from the target RNC, and provides the PLMN ID list to the UE. Upon receipt of a selected PLMN id from the UE, the source SRNC performs the SRNC relocation by selecting a CN operator corresponding to the selected PLMN id.

An apparatus and method for automatically searching for a low-power Base Station (BS) supporting access of a registered user in a mobile communication system includes a method of performing automatic search on a Closed Subscriber Group (CSG) cell by a User Equipment (UE). The method includes determining by the UE whether automatic search needs to be performed on the CSG cell. The method also includes, if it is determined that automatic search does not need to be performed on the CSG cell, turning off by the UE a CSG cell automatic search function of the UE by emptying a first white list including CSG Identifiers of accessible CSG cells.

Method is provided for communicating with a User Equipment (UE) supporting a High Power Saving Reception Mode (HPSRM) mode by an evolved Node B (eNB) in a wireless communication system. The method includes receiving Discontinuous Reception (DRX) cycle information from a network entity performing mobility management for the UE by the eNB communicating with the UE over a wireless link; and broadcasting system information including the DRX cycle information. The DRX cycle information is set longer than DRX cycle information of a UE non-supporting the HPSRM mode. By doing so, an efficient paging method for an UE operating in the HPSRM mode may be provided.
摘要:
An apparatus and method are provided for feeding back channel quality information and performing scheduling using the fed-back channel quality information in a wireless communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). In the OFDMA wireless communication system, forward performance degradation due to a decrease in an amount of reverse channel quality information is reduced, and also an increase in the reverse load due to channel quality information feedback is suppressed. A base station controls power of a physical channel using information fed back from a mobile station. In a method for feeding back channel quality information from the mobile station, sub-band-by-sub-band channel quality information is measured and channel-by-channel quality information of a number of channels is transmitted in order of sub-bands of better channel quality information. Average channel quality information for a total band is measured and transmitted.

An apparatus and method for providing handover support information in a mobile communication system are provided. A method for an Base Station (BS) to provide information necessary for measurement report trigger performance to a Mobile Station (MS) after the MS determines neighboring BSs in a mobile communication system includes, in a case where the MS is an active mode MS, providing a Time To Trigger (TTT) independently by a specific neighboring BS to the active mode MS and, in a case where the MS is an idle mode MS, providing a reselection time period (Treselection) independently by the specific neighboring BS to the idle mode MS.
摘要:
A method and an apparatus for transmitting and receiving System Information (SI) of a femto base station in a wireless communication system are provided. In the method, an SI transmission point is determined using unique identification information of a femto base station itself and unique identification information of a macro base station with which the femto base station is associated. Each of user equipment and the macro base station generate a measurement gap pattern representing an SI reception point using the unique identification information of the femto base station and the unique identification information of the macro base station. SI is received from the femto base station according to the generated measurement gap pattern.

Disclosed is a method of measurement on a home cell/private network cell, by a user equipment (UE), in a mobile communication system, the method including the steps of: transmitting a request message requesting the measurement to a network node, the request message including an indicator instructing at least one of register, join, and use of the home cell/private network cell; receiving a response message corresponding to the request message from the network node, the response message including context information for measurement control of at least one home cell/private network cell accessible by the UE; and selectively executing measurement on the accessible home cell/private network cell by using the context information.
摘要:
A method and a UE apparatus for radio resource management in a mobile communication system. When a discontinuous reception period or an inactivity period of a UE exceeds a threshold, an ENB releases resources for uplink control information transmission allocated to the UE, and the UE recognizes the release of the resources and stops transmitting the uplink control information through the resources. This reduces the explicit reconfiguration procedure through an RRC message, which is otherwise necessary whenever the UE enters a new discontinuous reception mode.

Methods and apparatus are provided for reporting a Power Headroom (PH) of a User Equipment (UE) in a wireless communication system having a plurality of aggregated uplink carriers. The PH is calculated for a Power Headroom Report (PHR)-triggered uplink carrier. A PHR having the PH and an identifier of the PHR-triggered uplink carrier is generated, and the PHR is transmitted to a network. Also, a PHR having the PH is generated, and the PHR is transmitted to a network over one of a plurality of PHR-transmitting uplink carriers configured to correspond to the PHR-triggered uplink carrier.
