20120134318 | METHOD AND APPARATUS OF PAGING AN IDLE MODE STATION IN MULTI-HOP RELAY COMMUNICATION SYSTEM - Disclosed is a method of paging an idle-mode terminal in a multi-hop relay communication system, the method including receiving an idle mode request message from the terminal, sending an idle mode response message to the terminal, the idle mode response message including paging information, receiving a superframe from a base station, the superframe including a paging message of the terminal, and staggering the superframe number by a multi-hop count apart from the base station so as to send to the terminal. | 05-31-2012 |
20120134331 | METHOD FOR TRANSMITTING CHANNEL QUALITY INDICATOR - Disclosed is a method for transmitting channel quality indicator (CQI) during a sleep mode operation. The method for transmitting CQI includes: receiving a message including a CQI-related parameter indicating a transmission of a CQI before a listening window; transmitting a CQI during a sleep window before the listening window according to a CQI-related parameter in the message; transitioning to the listening window according to a listening window-related parameter after transmitting the CQI; and waiting for receiving a message indicating whether or not there is data or traffic transferred from the base station during the listening window. | 05-31-2012 |
20120208493 | APPARATUS AND METHOD FOR PROVIDING AN EMERGENCY SERVICE IN A BROADBAND WIRELESS COMMUNICATION SYSTEM - Disclosed is a method of allowing a terminal to provide an emergency service in a broadband wireless communication system, and the method may include receiving a first map message including an emergency service indicator; checking whether information indicating that emergency service information is transmitted is included in the received first map message; and receiving a first message including the emergency service information when the information indicating that emergency service information is transmitted is included therein as a result of the check, wherein the emergency service indicator is information indicating at least one of whether to transmit emergency service information and a transmission timing of the emergency service information. | 08-16-2012 |
20120282927 | IDLE MODE TRANSITION CONTROL METHOD IN A WIREBAND WIRELESS COMMUNICATION SYSTEM - Disclosed is a method of controlling a transition to an idle mode in an operation method for transitioning to an idle mode in a wideband wireless communication system, including: receiving an unsolicited deregistration response message including an action code instructing the terminal to transmit a deregistration request message for a transition to an idle mode and deregistration request message transmission time information from a base station; extracting control information in which a poll bit for reporting whether or not a message has been received is set from the received unsolicited deregistration response message; transmitting a deregistration request message including response information with respect to the extracted control information and a deregistration request code for requesting a transition to an idle mode, to the base station; and receiving a deregistration response message including an action code permitting a transition to an idle mode, | 11-08-2012 |
20130064156 | METHOD AND APPARATUS OF SLEEP MODE OPERATION IN A MULTI-CARRIER SYSTEM - A method and apparatus of sleep mode operation in a multi-carrier system are discussed. The method of establishing a sleep mode operation through active primary and secondary carriers according to an embodiment of the present invention may include transmitting a sleep cycle ID, a listening window, and traffic indication inactive information indicating that an indication as to whether traffic is generated is not transferred to a terminal through the primary carrier, sending downlink data to the terminal through the active primary or secondary carrier during the listening window, and sending a listening window early termination indication indicating to early terminate the listening window of the primary or secondary carrier that has received the downlink data through the primary carrier to the terminal if the data sending is completed. | 03-14-2013 |
20130208640 | UPDATING METHOD AND APPARATUS OF SLEEP MODE OPERATION - Disclosed herein relates to a sleep mode operation method, and the method of updating a sleep mode operation according to the present invention may include receiving a service flow configuration request (DSx-REQ) message including a service flow parameter for service flow configuration and a sleep cycle ID (SCID) for changing a sleep mode according to the service flow configuration from a base station during a sleep mode listening window; transmitting a service flow configuration response (DSx-RSP) message including the SCID; configuring the service flow according to the service flow identifier; and changing an SCID to the SCID for updating the sleep mode operation. | 08-15-2013 |
20150055536 | METHOD AND APPARATUS OF SLEEP MODE OPERATION IN A MULTI-CARRIER SYSTEM - A method and a mobile station operating in a wireless communication system are described. Information on a primary carrier and one or more secondary carriers is received on a multi-carrier from a base station. Information on activation or deactivation of the one or more secondary carriers is received. The mobile station communicates with the base station via the primary carrier and one or more activated secondary carriers. Configuration information for power management is received that informs the mobile station of a first time period during which the mobile station monitors signals from the base station and of a second time period during which the mobile station does not monitor signals from the base station. When a specific indication is received from the base station, the mobile station stops the first time period and enters into the second time period. | 02-26-2015 |
