In RAN (Radio Access Network, wireless access network) #63 plenary session, LTE is reduced
The delay of network this problem comes into question.The delay of LTE network includes eating dishes without rice or wine to postpone, signal processing
Time delay, the transmission delay between node etc..With the upgrading of wireless access network and core net, transmit
Time delay is can be effectively reduced.With the application of the new quasiconductor for possessing higher height reason speed, signal
Process time delay to be significantly reduced.
In LTE, TTI (Transmission Time Interval, Transmission Time Interval) or
Subframe or PRB (Physical Resource Block) correspond to one in time to (Pair)
Individual ms (milli-second, millisecond).One LTE subframe includes two time slots (Time Slot)
- it is the first time slot and the second time slot respectively.PDCCH(Physical Downlink Control
