    • The present invention relates to a broadband wireless access system, and more specifically, to a structure of an efficient signaling header. A method for transmitting data from a transmission terminal to a receiving terminal, according to one embodiment of the present invention, comprises the steps of: creating a medium access control protocol data unit (MAC PDU) comprising a medium access control header (MAC header); and transmitting said MAC PDU to said receiving terminal, wherein said medium access control header comprises a first flow identifier field, an extended header field for indicating whether or not an extended header is included in said MAC PDU, and a length field for indicating the length of said MAC PDU. When said medium access control header is a signaling header, said first flow identifier field is set to a specific value indicating that said medium access control header is said signaling header, and signaling content information can be included in said extended header field and said length field.

    • Disclosed herein relates to a sleep mode operation method, and the sleep mode operation method according to the present invention may include transmitting a sleep request message for requesting sleep mode switching to a base station; receiving a sleep operating parameter including a sleep cycle and a listening window from the base station; referring to the sleep operating parameter to switch to a sleep mode; receiving a traffic indication message indicating that traffic is generated from the base station; receiving traffic from the base station during the listening window while at the same time operating a timer; and early terminating the listening window to enter into a sleep window if the timer operation is expired according to the traffic reception prior to terminating the listening window.
    • 本文涉及睡眠模式操作方法,并且根据本发明的休眠模式操作方法可以包括:向基站发送用于请求睡眠模式切换的睡眠请求消息; 从所述基站接收包括睡眠周期和监听窗口的睡眠操作参数; 参考睡眠操作参数切换到睡眠模式; 从基站接收指示业务量的业务指示消息; 在监听窗口期间接收来自基站的业务,同时操作定时器; 如果定时器操作在终止监听窗口之前根据业务接收到期,则提前终止监听窗口进入睡眠窗口。

    • Disclosed herein relates to a method and apparatus of establishing a sleep mode operation in a multi-carrier system. The method of establishing a sleep mode operation in a communication system of transmitting and receiving data using a multi-carrier including a primary carrier for transmitting and receiving control information and data and a secondary carrier using a radio frequency (RF) different from the primary carrier may include requesting a sleep mode switching to a base station through the primary carrier and receiving a sleep mode parameter including a sleep mode cycle and a listening window from the base station; entering into a multi-carrier sleep mode having a sleep cycle configured with a listening window capable of transmitting and receiving data and a sleep window incapable of transmitting and receiving data; transmitting a bandwidth request message to a base station through the primary carrier if data traffic to be is transmitted to the base station is generated in the multi-carrier sleep window;changing a sleep mode cycle of the primary carrier to terminate the sleep window of the primary carrier and enter into a listening window; changing a sleep mode cycle of the secondary carrier to be identical to the changed sleep mode cycle of the primary carrier; and transmitting uplink data traffic to the base station during the listening window of the changed sleep mode cycle through the primary carrier and secondary carrier.
    • 本文涉及在多载波系统中建立睡眠模式操作的方法和装置。 在使用包括用于发送和接收控制信息和数据的主载波的多载波发送和接收数据的通信系统中建立睡眠模式操作的方法和使用与主载波不同的射频(RF)的辅载波 可以包括通过主载波请求睡眠模式切换到基站,并从基站接收包括睡眠模式周期和监听窗口的睡眠模式参数; 进入具有配置有能够发送和接收数据的监听窗口的睡眠周期和不能发送和接收数据的睡眠窗口的多载波睡眠模式; 如果在多载波睡眠窗口中产生要发送到基站的数据业务,则通过主载波向基站发送带宽请求消息; 改变主载波的睡眠模式周期以终止主载波的睡眠窗口并进入监听窗口; 将次载波的睡眠模式周期改变为与主载波的改变的睡眠模式周期相同; 以及在改变的睡眠模式周期的监听窗口期间通过主载波和辅载波在基站发送上行链路数据业务。
