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?
