Wherein, the sequence of above two form can be sequence or scrambling code insensitive to bandwidth in communication system.
Step 102, when a predetermined condition is satisfied carries out scrambling code to signal to be transmitted using the sequence.
In embodiments of the present invention, the predetermined condition refers to the condition for needing to carry out scrambling code.As in which kind of situation
Under need to carry out scrambling code, have specific definition in existing 3GPP standard.
For the sequence of the first form, in this step, to the corresponding bit block of each code word q in signal to be transmittedScrambling code is carried out, obtains scrambled bits using following scrambling code formula:
Wherein,For the bit number transmitted on Physical Broadcast Channel；C (i) is c0(i) what any position intercepted in is continuous
231- 1 long short sequence, sequence c0(i) construction is as follows:

Step 203 is modulated the signal to be transmitted after scrambling code.
In this step, QPS modulation mainly is carried out to scrambled bits, obtains complex modulation symbols.
Step 204 carries out layer mapping and precoding to modulated signal to be transmitted.
Step 205 carries out resource unit mapping to the signal to be transmitted after layer mapping and precoding.
Wherein, step 204 is consistent with the respective process in LTE with 205 process, and details are not described herein.
In embodiments of the present invention, when the length of sequence is 2nWhen -1 (wherein n is even number), the maximum of the sequence is mutually
Pass value is minimum, the performance interfered with each other is resisted more preferably, to improve communication quality.
It in the prior art, is 2 when the period of sequencenWhen -1 (n is even number), currently used as sequence Gold code sequence it is mutual
Correlation be not it is optimal, it is not best for resisting the performance interfered each other；Sequence in LTE still can serve as after not supporting bandwidth to intercept
