Specifically, a scrambling code sequence (signal code after regular randomization) can be added to the CRC of the DCI, that is, scrambling (Scrambling, that is, using a pseudo-random code) The sequence multiplies the spreading code and encrypts the signal) to indicate that the terminal can perform a single measurement through the scrambling code sequence, such as Picture 9 The Scrambling shown is used to instruct the terminal to perform a single measurement, that is, a scrambling can be performed on the CRC to indicate that the terminal needs to perform a single measurement.
[0075] It should be noted that the interval between the subframe sent by the DCI and the subframe that the terminal needs to measure may be pre-configured, fixed, or configured through signaling.
