There is one section of blind area, blind area, which is appeared in, to be reconfigured carrier signalling and match somebody with somebody again with PHY layer to the MAC layer of the rrc layer signals base of base station
Put completion this process among, i.e., between base station and UE parameter configuration come into force moment point can existence time it is poor, the MAC layer of base station
Reconfiguring for rrc layer, which is received, with PHY layer completes signaling just meeting translated channel ACK feedback models, but this pilot process, UE is
The ACK feedback model new through employing, MAC layer and PHY layer for base station are difficult accurately to judge which moment point comes into force,
If the MAC layer of base station can be caused ACK decoding errors, then can so be caused to match somebody with somebody using the ACK feedback models decoding of mistake again
Put failure and service rate declines.
