Abstract:
Provided is a method for obtaining superframe header (SFH) information in a neighboring base station advertisement (NBR-ADV) message at a terminal. In the method, a NBR-ADV message having SFH information set per each carrier is received from a serving base station. The SFH information of each carrier is obtained from the NBR-ADV message. In the obtaining the SFH information of each carrier, SFH information of a corresponding carrier is obtained based on SFH information of a previous carrier when a predetermined field is set as a predetermined value.
Abstract:
PURPOSE: A control information transmission method and a response method thereof are provided to reduce overhead and the waste of resources. CONSTITUTION: A transmitter transmits a control message through payload of an MAC(Medium Access Control) PDU(Protocol Data Unit)(S500). A specific bit of an extended header is established as 1. The response of a receiver is required through the establishment. The receiver receives the control message from the transmitter. The receiver transmits the response through an MAEH(MAC control message ACK Extended Header)(S510).
Abstract:
PURPOSE: A method for receiving a mobile multicast broadcast service in a wireless communication system is provided to operate multi carrier operation by switching multi carrier for MBS service reception. CONSTITUTION: A DSA(Dynamic Service Addition) message is received from a base station through a primary carrier. The DSA message is switched from primary carrier to secondary carrier based on the DSA message. An MBS setting message is received from the base station. MBS data is received from the base station based on the MBS setting message.
Abstract:
PURPOSE: A location information providing method in a wireless communication system is provided to effectively and rapidly supply location information if a terminal is an idle state. CONSTITUTION: A LBS(Location Based Service) control information includes a type of wireless location method which determines a terminal location. If a terminal is an idle state, a determining method of the terminal location is performed by using procedures of paging or raging. A location information request message and a location information response message are messages related to a paging which is used in a paging procedure. The location information request message is a raging response message or a paging advertisement message. A terminal(20) is a location mode that has a location determination mode and information providing mode. The location determination mode is a mode performing final location determination or final location confirmation in a terminal. A base station(10) includes a location determination device(100), and a terminal includes a location information providing device(200).
Abstract:
PURPOSE: A modulating/coding method determining method and an apparatus thereof, and a feedback signal transmitting method of a terminal are provided to minimize the used amount of a feedback channel and rapidly determine a modulating/coding method. CONSTITUTION: A feedback channel includes first and second feedback channels. The feedback channel is used for transmitting a feedback signal to a terminal in an MCS(Modulation and Coding Scheme). The second feedback channel is used for transmitting the feedback signal to the terminal, which decodes multicast data. A feedback channel allocating unit(110) allocates feedback channel to a multicast group.
Abstract:
PURPOSE: A method for performing a handover in a wireless communication system is provided to improve total system performance. CONSTITUTION: A terminal transmits a handover request message to a service base station(S110). The terminal receives a handover indication message, which is a response about the handover request message(S140). The handover request message includes a pre-assigned request indicator indicating whether the terminal pre-assigns a multi carrier in a target base station during handover. The handover indication message includes a pre-assigned response indicator expressing whether the multi carrier is pre-assigned to the terminal.
Abstract:
PURPOSE: A method and an apparatus for transmitting neighbor base station information performed by a macro base station in a wireless communication system are provided to efficiently transmit information about an adjacent base station for handover when a terminal performs a handover from a macro cell to a femto cell, thereby efficiently transmitting information. CONSTITUTION: A terminal(120) searches adjacent base stations which are handover targets of the terminal. The terminal transmits preamble information about a base station searched by the terminal and a list request message to a macro base station(110). The list request message includes an adjacent base station list request indicator showing a request for information about the adjacent base station. The terminal receives a list response message including identification information for the adjacent base station and system information from the macro base station.
Abstract:
PURPOSE: A method for transmitting a paging message in a wireless communication system is provided to efficiently transmit a paging message in a hierarchical cell structure. CONSTITUTION: A second femto base station receives a paging request message, including a temporary ID, from a terminal(S241). The second femto base station stores the temporary ID in a terminal list. The second femto base station transmits a paging response message to the paging request message(S242). The second femto base station checks the temporary ID in the terminal list. The second femto base station transmits a paging message to the terminal(S244).
Abstract:
PURPOSE: A method of offering and receiving a reliable service is provided to rapidly support handover of lower terminals if the wireless interface operation of a femto cell base station is stopped. CONSTITUTION: A terminal#1 and a terminal#2 transmits and receives data to and from a femto base station#1(S210,S215). The terminal#2 transmits data to a macro bas station(S230), and the terminal#1 transmits and receives data to and from the femto base station#2(S235). If backhaul link is received, the femto base station#1 transfers service restoration information to neighbor bas stations(S240). The macro base station determines the handover of the terminal#2(S260), and the terminal#2 receives and transmits data from and to the femto base station#1(S275).
Abstract:
A method for transmitting paging information in a mobile communication system is provided to improve the utilization of limited radio resources by administrating the setting and mapping of a physical channel and a transport channel variably and flexibly. A paging channel(PCH) is formed in a transport channel corresponding to the occurrence of paging information. A paging indication channel(PICH) is set according to the paging information, and the PICH is added to radio resources of a physical layer(S140). The PCH is allocated to radio resources of the physical layer with a fixed position and a fixed size(S150). Scheduling information is allocated to a control channel of the physical layer. The scheduling information includes a scheduling identifier and radio resource allocation information. The scheduling identifier is used to distinguish between a specific terminal and a terminal group between a base station scheduler and a terminal.
