    摘要： The present invention relates to a power saving in a wireless local area network including a plurality of access points providing at least one mobile station in each access point cell boundary with access service, the mobile station transits between an active mode and an idle mode. The power saving method includes grouping the access points into at least one paging group with a paging group boundary; determining if the a mobile station is in the idle mode in which the mobile station switches between an awake state and a doze state every predetermined time interval, or the active mode in which the mobile station is in the awake mode; and if the mobile station is in the idle mode enabling an idle handoff which occurs only when the mobile station crosses the paging group boundary. In the present invention, the handoff occurs when the mobile terminal crosses the paging group boundary but not the access point cell in the idle mode, resulting in reduction of power consumption.

    摘要翻译： 本发明涉及无线局域网中的功率节省，该无线局域网包括在接入业务的每个接入点小区边界中提供至少一个移动台的多个接入点，该移动台在主动模式和空闲模式之间转换。 省电方法包括：将接入点分组成具有寻呼组边界的至少一个寻呼组; 确定移动台是否处于空闲模式，移动台在每个预定时间间隔在唤醒状态和打盹状态之间切换，或移动台处于唤醒模式的活动模式; 并且如果移动台处于空闲模式，使得仅当移动台跨越寻呼组边界时才发生空闲切换。 在本发明中，当移动终端在空闲模式中越过寻呼组边界而不是接入点小区时，发生切换，导致功耗的降低。

    摘要： Provided are a system and method of transmitting an Aggregated Media Access Control (MAC)Protocol Data Unit (A-MPDU) in a Wireless Local Area Network (WLAN) system. A MAC layer divides service data transferred from an upper layer into a plurality of MPDUs, forms a single transmission frame including the sequentially arranged MPDUs, delimiter information for distinguishing each of the MPDUs, and ACK request information for requesting for a reception result of the MPDUs, and transmits the formed transmission frame to a recipient. Accordingly, service coverage is extended, and a transmission delay is minimized, resulting in improved service efficiency.
