摘要:
Provided are a method and a device for entering a network for client cooperation in a wireless communication system. A first device, through a frame of a first system, receives a ranging request message from a second device, and transmits the received ranging request message to a base station. As a response thereto, the first device receives a range response message, which is a response to the ranging request message, from a base station of a second system, and through a frame of the first system, transmits the range response message to the second device.

Provided are a mode conversion method for client cooperation in a wireless communication system and a device thereof. A first device converts a second system repetitively into an active mode which can receive a signal and a non-active mode which cannot receive the signal based on mode conversion information, and detects at least one second device based on the second system in the active mode. The first device is connected to the base station through the second system and another first system.

The present invention relates to a method for updating secondary carrier information for preemptively allocating secondary carriers during handover and an apparatus for carrying out the method. A method in which a terminal performs handover in a broadband access system that supports multiple carriers according to one embodiment of the present invention comprises: a step in which a target base station receives, from a serving base station, a first message including carrier allocation information on at least one secondary carrier preemptively allocated to the terminal; a step of performing network reentry with the target base station; and judging whether the multi-carrier configuration of the serving base station and the multi-carrier configuration of the target base station are the same, and, if the configurations are different from each other, transmitting, to the target base station, a second message for requesting multi-carrier capability negotiation.

A method for data traffic offloading in a mobile communication system supporting a multi-radio access technology (RAT) and an apparatus using the method is provided. A mobile station receives information on a traffic load of a primary communication system from a base station. The mobile station determines whether to perform offloading to a secondary communication system on the basis of the traffic load of the primary communication system.

The present invention relates to a broadband wireless access system including a relay station, and more particularly to an efficient procedure of Automatic Repeat Request (ARQ) operations in a relay station and an apparatus for performing the same. A method for transmitting data for at least one terminal (AMS) from a base station (ABS) to a relay station (ARS) in the broadband wireless access system according to an embodiment of the present invention comprises the steps of generating second transmission unit data using a plurality of first transmission unit data to which different relay sequence numbers are assigned; and transmitting the second transmission unit data to the relay station. The second transmission unit data can be transmitted through the same tunnel as the first transmission unit data.

摘要:
A method and apparatus performing carrier management in a broadband wireless communication system supporting multi-carrier (MC) are disclosed. A method for a single-carrier supported mobile station (MS) to perform a carrier change with a MC supported base station (BS) includes transmitting a message indicating a support of a basic MC mode in which the MS is aware of a MC operation of the BS, receiving a carrier management command message including an action code and an action time on a serving carrier, transmitting, in response to the carrier management command message, a confirmation message indicating readiness of signal transmission/reception through a target carrier on a target carrier, and receiving a control signal and data from the BS on the target carrier, wherein the serving carrier and the target carrier are controlled by a common Medium Access Control (MAC) of the BS.
摘要:
A method of transmitting and receiving Automatic Repeat reQuest (ARQ) feedback information in a wireless communication system is disclosed. The method of transmitting ARQ feedback information in a wireless communication system includes, at a transmitter, transmitting a Protocol Data Unit (PDU) including an extended header including an ARQ feedback Polling Request (APR) field indicating whether or not the transmitter makes a request for ARQ feedback polling, and receiving an Acknowledgement (ACK) from a receiver if the APR field indicates that the transmitter makes the request for ARQ feedback polling to the receiver.
摘要:
A method and apparatus for transmitting and receiving control information in a wireless communication system are disclosed. The control information transmission method includes masking a Cyclic Redundancy Check (CRC) by a CRC mask including a bit stream of a predetermined length and an indicator indicating the bit stream, and transmitting control information including the masked CRC to at least one Mobile Station (MS). The indicator indicates whether the bit stream included in the CRC mask includes a Random Access IDentifier (RAID).
摘要:
A method of allocating a paging carrier in a multi-carrier environment is disclosed. The method of allocating the paging carrier includes receiving a first message including first allocation information of the paging carrier, transmitting a second message for requesting entry into an idle mode to a base station; and receiving a third message including second allocation information of a changed paging carrier from the base station. At this time, the paging carrier includes a paging channel out of multiple carriers including one or more carriers.
