    • The present invention discloses a remote radio head unit, a wireless communication system base station, and a data transmission synchronization method thereof. The wireless communication system base station comprises a remote radio head (RRH) and a baseband unit (BBU) communicably connected through a network, and wherein the BBU is used to process and transmit downlink data to the RRH, said wireless communication system base station further comprises: a time-delay measurement unit in the RRH which is used to measure a time-delay for the downlink data to arrive at the RRH from the BBU; a time-delay notification unit in the RRH for notifying from the RRH to the BBU of time-delay data on the time-delay measured by the time-delay measurement unit; a synchronization unit in the BBU for advancing the starting time for the BBU to process and transmit the downlink data by an amount of time obtained based on the time-delay data notified by the time-delay notification unit. The present invention can reduce or even eliminate the RRH reception time-delay caused by the BBU processing time-delay and data transmission jitter by measuring the time-delay for the downlink data frame to arrive at the RRH of the base station, and correcting the timing pulse for starting the downlink data processing and transmission on the BBU side.
    • 本发明公开了一种远程无线电头单元,无线通信系统基站及其数据传输同步方法。 无线通信系统基站包括通过网络可通信地连接的远程无线电头(RRH)和基带单元(BBU),并且其中BBU用于处理和发送下行链路数据到RRH,所述无线通信系统基站进一步 包括:RRH中的时间延迟测量单元,用于测量下行链路数据从BBU到达RRH的时间延迟; RRH中的延时通知单元,用于从RRH向BBU通知由延时测量单元测量的延时数据; BBU中的同步单元,用于使BBU的开始时间提前,以基于由延时通知单元通知的时间延迟数据获得的时间量来处理和发送下行链路数据。 本发明可以通过测量下行链路数据帧的时间延迟来达到基站的RRH,从而减少甚至消除由BBU处理时延和数据传输抖动引起的RRH接收延时, 用于开始BBU侧的下行链路数据处理和传输的定时脉冲。

    • A system for the delivery of chemical vasodilators into the skin for the purpose of increasing the blood flow in a tissue that exhibits compromised circulation. The designated purpose of this increased blood flow is to transiently reverse or inhibit or prevent the onset of an associated medical affliction that may in part or in whole, be either the consequence of that medical condition or participating in the clinical symptoms and etiology of that medical condition. The process and the effect of the topical delivery of a chemical vasodilator has been previously demonstrated for other medical and pharmaceutical applications, however the specific use of this class of drug molecules for the focused effect of improving blood flow to the skin and surrounding tissue with the goal of improving the metabolic health of the tissue and to possibly affect the symptoms of a medical condition is the specific aim of this patent.
