    • The present invention relates to a wireless access system, and more particularly, to a method for saving power of a femto base station. The present invention includes obtaining reference synchronization information used in a prescribed area to enable a first femto base station to perform a sleep mode operation, shifting to a sleep mode if a mobile station does not exist within the first femto base station, and enabling the first femto base station to be synchronized with at least one second femto base station belonging to the prescribed area using the reference synchronization information, wherein each of the femto base stations included in the prescribed area achieves synchronization of the sleep mode operation using the reference synchronization information. Accordingly, it is able to minimize power consumption of a femto base station and interference with a macro cell in a wireless access system supporting a femtocell. And, a mobile station within a femtocell is able to perform reliable communications.
    • 用于节省毫微微基站的功率的方法技术领域本发明涉及无线接入系统,更具体地涉及用于节省毫微微基站的功率的方法。 本发明包括:获得在规定区域中使用的参考同步信息,以使得第一毫微微基站能够执行睡眠模式操作;如果第一毫微微基站内不存在移动台,则转换到睡眠模式;以及使得第一毫微微基站 毫微微基站使用所述参考同步信息与属于所述指定区域的至少一个第二毫微微基站同步,其中,所述指定区域中包括的每个毫微微基站使用所述参考同步信息实现所述休眠模式操作的同步。 因此,能够使支持毫微微小区的无线接入系统中的毫微微基站的功耗和对宏小区的干扰最小化。 而且,毫微微蜂窝内的移动台能够执行可靠的通信。

    • A method for allocating multiple radio communication periods to an MS supporting co-existence mode is disclosed. The method includes transmitting a co-existence mode request message to a BS by the MS, receiving information about the position of a start frame for the co-existence mode by a co-existence mode response message as a response to the co-existence mode request message from the BS by the MS, and receiving information about an allocated Wi-Fi beacon reception period by an unsolicited co-existence mode response message in the start frame from the BS by the MS. A frame allocation pattern for allocating periods for communications with a Bluetooth or Wi-Fi system using a frequency band adjacent to that of an IEEE 802.16m system can be provided according to an IEEE 802.16m frame structure, and an MS with multiple radio interfaces can communicate with each system reliably, while minimizing interference between systems.
    • 公开了一种用于将多个无线电通信周期分配给支持共存模式的MS的方法。 该方法包括通过MS向BS发送共存模式请求消息,通过共存模式响应消息接收关于共存模式的起始帧的位置的信息作为对共存模式的响应 通过MS从BS发送请求消息,并且通过MS从BS在起始帧中通过未经请求的共存模式响应消息来接收关于分配的Wi-Fi信标接收周期的信息。 可以根据IEEE 802.16m帧结构提供用于使用与IEEE 802.16m系统相邻的频带与蓝牙或Wi-Fi系统通信的帧的分配模式,并且具有多个无线电接口的MS可以 可靠地与每个系统通信,同时最小化系统之间的干扰。
