Abstract:
Disclosed herein is a method for transmitting feedback information on the downlink of a carrier to a base station in a multicarrier system, and the method may include receiving a first message including uplink feedback allocation information from the base station through a secondary carrier, and transmitting uplink feedback information on the secondary carrier to the base station over an assigned uplink feedback channel of a primary carrier when the secondary carrier is a downlink only activated carrier.
Abstract:
The present invention relates to a method and apparatus for transmitting and receiving data in a wireless communication. In a communication performed by a user equipment supporting a multi-RAT (multi-radio access technology), the present invention includes receiving a 1st information for identifying a 1st cooperative user equipment candidate from the 1st cooperative user equipment candidate corresponding to at least one of a plurality of cooperative user equipment candidates, transmitting the 1st information to a base station, receiving an information on at least one 2nd cooperative user equipment candidate determined among the at least one 1st cooperative user equipment candidate using the 1st information from the base station, and performing a communication of a 1st data with the base station in cooperation with the at least one 2nd cooperative user equipment candidate. Moreover, the user equipment and a plurality of the cooperative user equipment candidates support a direct communication without using an access point.
Abstract:
The present description relates to a method in which a first terminal communicates with a base station via a second terminal in a wireless access system supporting machine-type communication (MTC). The method comprises the following steps: transmitting, to the second terminal, uplink data to be transmitted to the base station; receiving, from the base station, control information corresponding to the quality of a link between the first terminal and the second terminal; and retransmitting the uplink data to the second terminal in accordance with the received control information, wherein the control information includes information on the delay between the second terminal and the base station, and information on the measured quality of the link between the first terminal and the second terminal.
Abstract:
The present invention provides a method for receiving a paging message of an idle-mode terminal in a multi-carrier system, comprising the steps of: receiving, from a network, a paging message through a first carrier corresponding to a predetermined condition in a paging listening interval; transmitting, to the network, a first ranging request message that includes control information indicative of a location updating procedure for notifying a start of E-MBS service reception; determining, as a paging carrier, a second carrier from which an E-MBS service is transmitted; and receiving the paging message from the network through the determined second carrier.
Abstract:
The present description relates to a method in which a multi-radio access technology (RAT) terminal transceives data to/from a first base station that supports a first RAT and to/from a second base station that supports a second RAT, in a radio access system which supports multi-radio access technologies (RATs). The multi-RAT terminal transmits, to the first base station, a multi-RAT capability negotiation request message containing control information indicating the second base station which is preferred for communication, thereby simplifying a scanning process for the second base station and thus reducing the power consumption of the multi-RAT terminal.
Abstract:
A method and apparatus for receiving data at a mobile station in a wireless communication system are disclosed. A method of receiving data mobile station in a wireless communication system includes receiving an Advanced Air Interface Traffic Indication (AAI_TRF-IND) message including a positive indicator during a listening window from a base station, and receiving a traffic by extending the listening window without restriction as to an extension range of the listening window from the BS if there is traffic to be transmitted to or received from the base station after the listening window.
Abstract:
Disclosed is a method for operating a terminal for receiving E-MBS (enhanced-multicast and broadcast service) service in a multicarrier system, the method comprising: establishing E-MBS service connection with a base station; sending, to the base station, a first message including report mode information when the terminal receives E-MBS service from the base station; wherein the report mode information indicates the terminal requests the base station to assign a carrier switching operation start time, receiving, from the base station, a second message including the carrier switching operation start time information requested by the terminal; and starting a carrier switching operation based on the received carrier switching operation start time information.
Abstract:
Disclosed is a method of driving a terminal for receiving a broadcast control message formed of a MAC PDU from a wireless access system. The method includes receiving at least one broadcast control message from a base station in a resource region where a broadcast control message is transmitted, extracting broadcast control message type information that represents the kind of a broadcast control message included in the header of the received broadcast control message, and checking the extracted broadcast control message type information and determining whether payload of the received broadcast message is decoded.
Abstract:
A wireless access system and, more particularly, a method and apparatus for more efficiently performing zone switch are disclosed. The method of performing zone switch by an advanced mobile station (AMS) in a mixed-mode advanced base station (ABS) which operates in a mixed mode of a broadband wireless access system includes receiving a ranging response (RNG-RSP) message including system information of an AMS support zone from a legacy zone (LZone) of the ABS, and performing ranging to the AMS support zone using the system information.
Abstract:
The present invention relates to a broadband wireless access system, and more particularly, to a method for efficiently determining power for ranging performed by a terminal on a target base station or a target region during handover or during changing of a region. A method for controlling uplink power for network reentry of a terminal from a first region to a second region in a broadband wireless access system, according to an embodiment of the present invention, comprises the steps of: receiving a media access control (MAC) management message including a power control parameter that is to be applied to the second region from the first region; and performing ranging to the second region by applying the power control parameter.
