To part capture instruction information capture indicator sequence whether corresponding with targeting signal match, judged according to matching result
It may include following steps that whether part capture instruction information, which has responded the flow chart of targeting signal:
Step 1431, the matching for judging first part's capture instruction information capture indicator sequence corresponding with targeting signal
Whether value is 0, when the first part captures the matching of instruction information capture indicator sequence corresponding with the targeting signal
When value is 0, judges that the part capture instruction information does not respond targeting signal, execute step 1432, more new physical layer connects at random
After the configuration information for entering process, the first random access procedure is re-initiated；When the first part capture instruction information with it is described
When the matching value of the corresponding capture indicator sequence of targeting signal is not 0, step 1433 is executed, judges first part's capture

The transmission power for the targeting signal that step 151, acquisition are estimated.
When the channel quality of terminal device is bad, needing to receive whole capture instruction information can just detect that capture refers to
Show whether information has responded targeting signal, consumes the more time due to receiving all capture instruction information, leave end for
The time that end equipment carries out data selection and data processing is shorter, and therefore, the physical layer of terminal device, will according to itself situation
The transmission power for the targeting signal estimated is sent to high level.
The transmission power of step 152, the targeting signal estimated according to selects the transmission content of message part.
The data format for sending power and carrying out message part for the targeting signal that the high level of terminal device is estimated according to
Selection.
Step 153 randomly chooses a targeting signal serial number according to the configuration information of physical layer random access procedure, in the past
It leads and selects leader signal sequence corresponding with targeting signal serial number in signal sequence set and send comprising leader signal sequence
Targeting signal.
The configuration information may include the letter such as the initial transmission power of targeting signal and the maximum retransmission of targeting signal
Breath.
Step 154, the whole received in capture instruction information corresponding with targeting signal capture instruction information.
In this step, 32 bit informations for receiving capture instruction information are sentenced according to all captures instruction information
Whether disconnected capture instruction information has responded the targeting signal.
All the capture instruction information matching value for capturing indicator sequence corresponding with targeting signal is for step 155, judgement
No is 0, when the matching value is not 0, executes step 156, judges that all capture instruction information is opposite with the targeting signal
Whether the matching value for the capture indicator sequence answered is -1, when the matching value is 0, executes step 158, increases the leading letter
Number transmission power.
In this step, 32 bits and targeting signal for whole capture instruction information that terminal device is received are corresponding
Capture indicator sequence 32 bits carry out bit multiplication, matching value is judged according to the result of addition.
Assuming that the serial number U for the targeting signal that terminal device is sent, the ratio of the corresponding capture indicator sequence of targeting signal
Special position indicates that the bit of capture instruction information indicates that number of bits is indicated with s with R with b, ifIt is greater than
5th detection threshold, then matching value is 1, and the 5th detection threshold is judgement all capture instructions in the second random access procedure
