    • A method for transmitting wireless data using a piggyback technique includes the steps of: a) transmitting a predetermined request packet from a first communication unit to a second communication unit in a predetermined wireless network system; b) determining, by the second communication unit having received the request packet, whether to sequentially transmit an acknowledgement (ACK) packet indicating an acknowledged or unacknowledged state of the request packet and a data packet responding to the request packet to the first communication unit; and c) if it is determined that the ACK packet and the data packet should be sequentially transmitted, including, by the second communication unit, ACK information in a header of the data packet without transmitting the ACK packet to the first communication unit, and transmitting the data packet including the header equipped with the ACK information to the first communication unit.
    • 一种使用背负技术发送无线数据的方法包括以下步骤:a)将预定请求分组从第一通信单元发送到预定无线网络系统中的第二通信单元; b)由已经接收到请求分组的第二通信单元确定是否将指示请求分组的确认或未确认状态的确认(ACK)分组和响应于请求分组的数据分组发送到第一通信单元; 以及c)如果确定应该顺序地发送ACK分组和数据分组,包括由第二通信单元在数据分组的报头中的ACK信息,而不向第一通信单元发送ACK分组,并且发送 所述数据分组包括配备有所述ACK信息的报头给所述第一通信单元。

    • The invention provides a wireless personal area network (WPAN) device, in which a beacon reception interval is set to vary in response to data reception and the power level of the device and a method for controlling beacon reception thereof. The WPAN device includes a receiver for receiving beacons at a predetermined interval, a frame analyzer for analyzing beacons, and a data-storing part for storing the information analyzed by the frame analyzer. The device further includes a traffic monitor for monitoring data reception, a power level detector for detecting power level, a beacon interval setter for setting the beacon interval in response to data reception and the power level, and a reception controller for controlling the beacon reception according to the set interval. A method for managing low power consumption in the WPAN device is also proposed.
    • 本发明提供了一种无线个人区域网络(WPAN)装置,其中信标接收间隔被设置为响应于数据接收和设备的功率电平而变化,以及一种用于控制信标接收的方法。 WPAN设备包括用于以预定间隔接收信标的接收机,用于分析信标的帧分析器,以及用于存储由帧分析器分析的信息的数据存储部分。 该装置还包括用于监视数据接收的流量监视器,用于检测功率电平的功率电平检测器,用于响应于数据接收和功率电平设置信标间隔的信标间隔设置器,以及用于根据数据接收和功率电平控制信标接收的接收控制器 到设定的间隔。 还提出了一种用于管理WPAN设备中的低功耗的方法。
