Another way to understand why we discard that extra bit is to remember that the leftmost bit of the lower number possesses a negative weight, in this case equal to negative eight. 另一种方式来理解我们为什么放弃额外位是要记住,最左边的位低一些具有负面重量,在这种情况下,等于否定8。
The bit order of each parameter field within a PDCP PDU is represented with the first and most significant bit in the leftmost bit and the last and least significant bit in the rightmost bit. PDCPPDU每个参数域的比特的顺序是第一个和最重要的在最左边,最不重要的最后一个在右边。
