Abstract:
A plurality of location-based service advertisement messages including location information of base stations belonging to each network are broadcasted with different timing in multiple wireless networks. Therefore, a terminal receives only at least on location-based service advertisement message corresponding to an accessible network among the plurality of location-based service advertisement messages.
Abstract:
Provided is a method in which a terminal receives multicast broadcast service in a wireless communication system. The method for receiving multicast broadcast service comprises the following steps: receiving a dynamic service addition (DSA) message from a base station via a primary carrier; switching the primary carrier into a secondary carrier on the basis of the DSA message; receiving an MBS configuration message (MBS-CFG) from the base station via the secondary carrier; and receiving the MBS data from the base station via the secondary carrier on the basis of the MBS configuration message.
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:
In a method of acquiring broadcast information acquisition, the terminal receives partial broadcast information from a base station, and transmits an initial access message including indication for the partial broadcast information to the base station. The terminal receives an initial access response message including broadcast information other than the partial broadcast information.
Abstract:
A method for handover of the present invention is a method for handover of a terminal supporting a multi-carrier including a first carrier and a second carrier, the method including: transmitting a handover request message to a serving base station; receiving a handover response message from the serving base station according to a handover response message transmitted from a target base station to the serving base station; after receiving the handover response message from the serving base station, transmitting and receiving data to and from the serving base station using the first carrier; and performing a handover signaling process to the target base station using the second carrier.
Abstract:
In a retransmission control method, a HARQ process is performed by transmitting a HARQ burst to a receiving side. When the HARQ process for the HARQ burst is terminated with unsuccessful transmission of the HARQ burst, transmission of an ARQ block corresponding to the HARQ burst is initiated.
Abstract:
The base station control method according to the present invention is a control method for controlling the operating mode of the base station, comprising the steps of: judging whether a terminal is not present inside a cell controlled by the base station; and running in a low-duty operation mode (LDM) if the terminal is not present in the cell.
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.
