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:
Provided is a management method for a user terminal MBS settings data, wherein an MBS setting message, which contains settings data for MBS operation and the effective period, is decoded, and the MBS settings message, which is transmitted at the moment designated by the effective period, is subsequently decoded again.
Abstract:
According to one embodiment of the present invention, a method in which a terminal acquires data about superframe headers in neighbouring base station advertisement messages comprises the steps of: receiving, from a serving base station, a neighbouring base station advertisement message in which data relating to superframe headers has been set differentiated according to carrier wave; and acquiring, from the neighbouring base station advertisement message, carrier-wave-differentiated data relating to the superframe headers of the carrier waves; and if, in the process of acquiring the data relating to the superframe headers of the carrier waves, a predetermined field has been set to a specific value, then data relating to the superframe header of the relevant carrier wave is acquired by using data relating to the superframe header of the previous carrier wave.
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:
A transmitting device for a multicast and broadcast service according to an embodiment of the present invention includes: an encoder that receives data to generate parity; an ARQ block generator that generates a first automatic repeat request (ARQ) block by dividing the data and generates a second ARQ block by dividing the parity; a PDU generator that generates a first protocol data unit (PDU) including the first ARQ block and a second protocol unit (PDU) including the second ARQ block; and a transmitter that transmits the first PDU and the second PDU to a plurality of terminals.
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.
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:
An apparatus for allocating a feedback channel basically configures a feedback channel transmitting the success or failure of reception of data as a plurality of unicast feedback channels. Then, when multicast data to be transmitted to a terminal are existed, at least some of the plurality of unicast feedback channels are configured as multicast feedback channels.
