20 Claims

1. A message sending method, comprising:

generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression:

c_init=R·2^a^₇+P·(ⁿ^_fmod ^k+1)·2^b^₇

where c_initis the scrambling code initialization seed, R is a function of n_RNTI, a₇is a non-negative integer, P is a function of a cell identity, n_fis the a frame number of a message, k is a prime number, and b₇is a non-negative integer;

scrambling the message according to the scrambling code to render a scrambled message; and

sending the scrambled message to a terminal on a physical downlink shared channel,

wherein the message is a system message, a part of a system message, an encoded system message, or a part of an encoded system message, and

wherein the system message is a system information block.
