Step 3, UE->BS：NR-PRACH (feedback best-M coarse beam).
In above-mentioned steps, BS indicates that base station, UE indicate terminal ,->Indicate signal transmission direction.In above-mentioned steps one, base
It stands and periodically sends-primary synchronization signal (NR-PSS, the New Radio-Primary that newly eats dishes without rice or wine by way of beam scanning
Synchronization Signal) and/or-secondary synchronization signal (NR-SSS, the New Radio-Secondary that newly eats dishes without rice or wine
Synchronization Signal), in general, in order to be compatible with different system bandwidths, NR-PSS and/or NR-SSS are usual
It is sent in minimum system bandwidth (or system centre frequency band), due to the use of analog beam figuration, for example, in some symbol of time domain
Number wave beam in some direction sent is only capable of subregion relatively narrow in coverage cell, if sending the business datum of some terminal
Then be difficult to ensure that the terminal can receive, therefore, send NR-PSS and/or NR-SSS at the time of in other band resources very
Difficulty is used for the Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) of business datum
Transmission, while the optimal beam for only leaning on the enterprising traveling wave beam scanning of minimum system bandwidth to select may for whole system bandwidth
It is not optimal, this can also reduce the performance of subsequent data transmission.
