Abstract:
Provided is a method in which a base station updates system information using a superframe structure in a wireless communication system. The method comprises: a step of transmitting a primary header containing system scheduling information related to updating system information; and a step of transmitting an updated secondary header. User equipment may determine when to apply the updated system information using the information applied in the secondary header.
Abstract:
A multi-carriers management device of a communication system supporting multi-carriers requests a terminal attempting to enter a sleep window to change a primary carrier, and transmits a control message to the terminal through the changed primary carrier during the sleep window.
Abstract:
Disclosed is a method for executing handover from a service base station to a target base station for providing service to a terminal in a wireless communication system. The method comprises the steps of: transmitting a handover request message to the service base station; and receiving a handover instruction message, constituting a response to the handover request message, from the service base station. Multi-carriers can be used effectively by pre-allocating multi-carriers immediately before handover, and activating some or all of the multi-carriers immediately after handover.
Abstract:
Disclosed is an operating method of a femto base station. The method comprises the steps of: transmitting information related to a first Low Duty Operation (LDO) pattern including length information of Available Interval (AI) as an active state of the femto base station and length information of Unavailable Interval (UAI) as an inactive state of the femto base station, to a terminal; and operating on the basis of the first LDO pattern formed by repeating a first LDO cycle that is a sequence of the AI and the UAI, wherein the information related to the first LDO pattern further includes a super frame offset that is information inducing a starting point of the first LDO cycle.
Abstract:
Provided is a method in which a terminal makes a request for neighbor base station information in a wireless communication system. The method comprises: a step of searching for neighbor base stations as an object for the handover of the terminal; a step of transmitting, to a serving base station, preamble information on the base station searched for by the terminal from among the neighbor base stations and a list request message containing a neighbor base station list request indicator for indicating a request for information on neighbor base stations; and a step of receiving, from the serving base station, a response list message containing neighbor base station identification information and system information.
Abstract:
Disclosed is a method for providing reliable service in a wireless communication system. The method comprises the steps of: broadcasting, to a terminal, service disability information which shows that a femto base station is not able to provide a service; and setting cell bar indication for indicating that the entry to the femto base station is prohibited. The service disability information includes identification information on a recommended base station which is another base station that the terminal is able to enter. In addition, the present invention provides a method for receiving reliable service by a terminal in a wireless communication system. The method comprises a step of receiving, from a femto base station, service disability information which shows that a service is not able to be provided to the terminal, wherein the service disability information includes identification information on at least one recommended base station which is another base station that the terminal can enter, and the terminal attempts to enter one of the at least one recommended base stations on the basis of the service disability information.
Abstract:
According to the present invention, a carrier management method in which a mobile station that supports multiple carriers manages a primary carrier, wherein the method comprises the steps of receiving a primary carrier change command from a base station; and changing the primary carrier from a serving primary carrier to a target primary carrier.
Abstract:
A multi-carriers management device of a communication system supporting multi-carriers requests a terminal attempting to enter a sleep window to change a primary carrier, and transmits a control message to the terminal through the changed primary carrier during the sleep window.
Abstract:
A method in which a terminal that supports a multi-carrier manages a primary carrier, including: receiving a primary carrier change command from a base station; and changing the primary carrier from a serving primary carrier to a target primary carrier.
