Claim 0:
1. A scrambling information processing method, comprising:
determining, by a network device, first information, the first information being associated with at least a preamble;
determining, by the network device, initialization information for scrambling at least based on the first information;
receiving, by the network device, a Physical Uplink Shared Channel (PUSCH) transmitted by a terminal; and
descrambling, by the network device, the PUSCH based on the initialization information,
wherein the first information comprises a preamble index,
wherein the determining, by the network device, the initialization information for scrambling at least based on the first information comprises:
determining, by the network device, the initialization information for scrambling based on a fourth parameter, a second parameter, and the preamble index, the fourth parameter corresponding to a Radio Network Temporary Identity (RNTI) associated with PUSCH transmission, and the second parameter being a specific value, wherein the specific value of the second parameter is within a first preset value range under a condition of satisfying a first preset condition, and corresponds to a cell identifier under a condition of not satisfying the first preset condition; and a maximum value within the first preset value range is 1023.
