Receive, then again under subsynchronous access phase frame number N-1+N, issue access distance measurement value TA, for terminal carry out access process.
Step S10C: after the angled all wheels hair of institute is primary, into the communication scheduling stage, at frame number N to M-1, the angle [a, N*a]
There is the terminal of access on degree, directly dispatch business in certain subframe, carries out the transmitting-receiving of figuration business using the angle of known terminal.
It is as follows for the process flow of terminal:
Step S201: in frame, according to b angular acceptance wave beam, base station downlink signal is received, carries out down-going synchronous；
Step S202: if not synchronizing success, in next cycle 2*T, according to 2*b angular acceptance wave beam, base is received
It stands downlink signal, carries out down-going synchronous；
Step S20N: if not synchronizing success, until, according to N*b angular acceptance wave beam, receiving base station down letter in N*T
Number, down-going synchronous is carried out, such as continues to recall to step S201 not successfully；
Step S20M: if not synchronizing success, in T to N*T next time, according to (N+1) * b to L*b angular acceptance wave
Beam receives base station downlink signal, carries out down-going synchronous, such as continues to recall to step S201 not successfully；
Step S301: during step S201 to step S20M, go to step S302 if down-going synchronous, is connect
Enter process；
Step S302: synchronous corresponding angle is x*b, it is assumed that it in corresponding frame number is x, using corresponding angle x*b, and, carry out
PRACH signal is sent；
Step S303: assuming that base station receives PRACH signal in z*a angle, and msg2 message is issued.Terminal is right next time
The frame number x+M answered receives the frame distance measurement value TA of base station, such as success, then carries out step S304.Continue to go to step if failure
S302.
Step S304: the frame number set ((x+y*M) mod1024) of business processing can be then carried out in correspondence, wherein y value
For positive integer, the angle that terminal correspondence can do business is x*b, completes access process；
Step S30C: if terminal needs business to need to receive and dispatch, the terminal message is received and dispatched in z*a angle in base station, and terminal exists
Normal business transmitting-receiving process is completed in transceiver base station message in x*b angle, terminal and base station；
Step S305: whether real-time judge is in access state (whether PBCH demodulation succeeds), and step is carried out if step-out
S201 re-starts synchronous access；It is such as in access state, continues step S30C, carries out normal business processing.
By this method, moderate distance terminal outside original covering provides communication service for the Terminal Type.Effectively mention
Signal quality is risen, higher service traffics and entire system capacity are provided.
