Claim of US Patent No. 11,115,985


1. A scrambling method, comprising:scrambling a physical broadcast channel (PBCH) according to a first scrambling code of the PBCH, wherein the first scrambling code is one of four scrambling codes, wherein a value of a combination of a second least significant bit and a third least significant bit of a system frame number (SFN) of a radio frame of the PBCH is one value of four values, the four values comprising 00, 01, 10 and 11, wherein the four scrambling codes have a one-to-one correspondence with the four values, and wherein the first scrambling code corresponds to the value of the combination of the second lesat significant bit and the third least significant bit of the SFN,
wherein the SFN comprises ten bits, wherein the third least significant bit is in an eighth bit place in the ten bits of the SFN, wherein the second least significant bit is a ninth bit place in the ten bits of the SFN, and
sending the PBCH to a terminal device.
