如下面这段协议：

If no Random Access Response is received within the RA Response window, or if none of all received Random Access Responses contains a Random Access Preamble identifier corresponding to the transmitted Random Access Preamble, the Random Access Response reception is considered not successful and the UE shall:

- increment PREAMBLE_TRANSMISSION_COUNTER by 1;

- If PREAMBLE_TRANSMISSION_COUNTER = preambleTransMax + 1:

- if the Random Access Preamble is transmitted on the PCell:

- indicate a Random Access problem to upper layers;

- if the Random Access Preamble is transmitted on a SCell:

- consider the Random Access procedure unsuccessfully completed.

如果没收到RAR（或preamble不一致），且preamble传输次数已达到最大，入股RA发生在SCell，就认为RA完全失败了。

那之后呢？UE是会继续在SCell上发preamble吗？还是UE认为已经失败了就放弃接入这个SCell了？
