A scrambling information processing method, comprising: determining, by a network device, first information, the first information being associated with a preamble; and 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; 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, the method characterized in that the initialization information satisfies: c init = n RNTI ⋅ 2 15 + n preamble − ID ⋅ 2 10 + n ID, wherein c init represents the initialization information; n RNTI corresponds to the RNTI associated with PUSCH transmission; n preambie-ID represents the preamble index; a value of n ID 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. determining, by a network device, first information, the first information being associated with a preamble; and 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; 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, the method characterized in that the initialization information satisfies: c init = n RNTI ⋅ 2 15 + n preamble − ID ⋅ 2 10 + n ID, wherein c init represents the initialization information; n RNTI corresponds to the RNTI associated with PUSCH transmission; n preambie-ID represents the preamble index; a value of n ID 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. 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, the method characterized in that the initialization information satisfies: c init = n RNTI ⋅ 2 15 + n preamble − ID ⋅ 2 10 + n ID, wherein c init represents the initialization information; n RNTI corresponds to the RNTI associated with PUSCH transmission; n preambie-ID represents the preamble index; a value of n ID 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.
