在LTE中SI-window是什么
在LTE中SI-window是什么含义，协议中出现很多，SI代表的是System Information 吗？

广播消息分三种,
主块mib, 40ms一个周期
sib1,调度块,80ms一个周期
对于其他的sib, 则每个si都有一个si-window,
The SI messages are transmitted within periodically occurring time domain windows (referred to as SI-windows) using dynamic scheduling. Each SI message is associated with a SI-window and the SI-windows of different SI messages do not overlap. That is, within one SI-window only the corresponding SI is transmitted. The length of the SI-window is common for all SI messages, and is configurable. Within the SI-window, the corresponding SI message can be transmitted a number of times in any subframe other than MBSFN subframes, uplink subframes in TDD, and subframe #5 of radio frames for which SFN mod 2 = 0. The UE acquires the detailed time-domain scheduling (and otherinfo rmation, e.g. frequency-domain scheduling, used transport format) from decoding SI-RNTI on PDCCH

SI-window就是系统消息发送周期

与2/3G同，在LTE系统中系统消息是根据需要灵活配制的，而SI-window是系统消息配制的具体内容！
