Let the specific form of the Zadoff-Chu sequence of length 11 be:

Among them, when M=4, it is necessary to determine 64 cases at most, so the value range of q is recommended to be [0, 64]. Here, when q=0, the scheme corresponding to the ACK mapping table specified by the existing protocol is adopted.

The generated sequence has a length of 11, which can be represented as X(0), X(1), ... (11), respectively, and X(0) = X(11).

That is, generating a reference signal sequence;

Step 603: Process the reference signal sequence obtained after the processing in step 602 and the actual data to be sent to obtain a complex value symbol.

As can be seen from the flow depicted in FIG. 5 and FIG. 6, in the process of generating a complex-valued symbol, the base sequence is bit-multiplied in the present embodiment.

Operation.

Step 406: After receiving the complex value symbol in the PUCCH format 1b mode sent by the UE, the base station demodulates and obtains a base sequence with a constant envelope zero autocorrelation sequence.

Step 407: The base station performs inverse processing on the obtained base sequence to obtain a constant envelope zero autocorrelation sequence, and confirms corresponding ACK/NACK information by using a constant envelope zero autocorrelation sequence.

Here, after obtaining the constant envelope zero autocorrelation sequence, the base station can obtain the value of q, thereby obtaining the ACK/NACK information fed back by the UE.

As can be seen from the above description, the solution provided by this embodiment uses a constant envelope zero autocorrelation sequence to indicate corresponding ACK/NACK information, so that when M=3 and M=4, the base station can clear the UE feedback. The ACK/NACK information, in turn, reduces the waste of channel resources caused by unnecessary retransmissions.

Encapsulating a zero autocorrelation sequence, obtaining an updated base sequence; generating the complex value symbol by using the updated base sequence, and transmitting the complex value symbol to a receiving device; and using the received complex value symbol to obtain a corresponding base sequence; The base sequence is de-added to obtain a constant envelope zero autocorrelation sequence; the obtained constant envelope zero autocorrelation sequence is used to confirm the corresponding ACK/NACK information, and the constant envelope zero autocorrelation sequence has characteristics, so The constant acknowledgment zero auto-correlation sequence can be used to indicate the corresponding ACK/NACK information, and when the sending device selects the resource corresponding to the any item in the ACK mapping table when M=3 or M=4, the receiving device can clearly know each sub-recognition. Corresponding ACK/NACK information in the frame, thereby reducing waste of channel resources caused by unnecessary retransmission.
