receiving network configuration information, wherein the network configuration information comprises identification information for indicating a target transmission reception point;
generating uplink information corresponding to the identification information of the target transmission reception point based on the identification information of the target transmission reception point; and
transmitting the uplink information;

obtaining an initial value of a scrambling sequence of an uplink channel based on the identification information of the target transmission reception point;
generating the scrambling sequence of the uplink channel based on the initial value of the scrambling sequence of the uplink channel; and

calculating the initial value c init of the scrambling sequence of the uplink channel based on following formula,
c init =n RNTI □2 15 +n ID +n,

where n is related to the identification information of the target transmission reception point, and different transmission reception points correspond to different values of n; n RNTI is obtained based on a C-RNTI; in response to n ID being configured by a higher layer, the n ID represents a data scrambling ID of a Physical Uplink Shared Channel configured by a higher layer, otherwise the n ID represents a cell ID.

2. The method according to claim 1 , wherein said generating the uplink information corresponding to the identification information of the target transmission reception point based on the identification information of the target transmission reception point comprises:
obtaining an initial value of an uplink reference signal based on the identification information of the target transmission reception point; and
generating the uplink reference signal based on the initial value of the uplink reference signal.

3. The method according to claim 2 , wherein said obtaining the initial value of the uplink reference signal based on the identification information of the target transmission reception point comprises:
calculating the initial value c init of the uplink reference signal based on following formula,
c init =(2 17 ( N symb slot n s,f μ +l+ 1)(2 N ID 0 +1)+2 N ID 0 +n )mod 2 31

wherein, n is related to the identification information of the target transmission reception point, and different transmission reception points correspond to different values of n; l represents an OFDM symbol number within a slot, n s,f u represents a slot number in a radio frame f with a subcarrier spacing μ; in response to N ID 0 being configured by a higher layer, the N ID 0 represents a scrambling ID configured by a higher layer, otherwise the N ID 0 represents a cell ID.

4. The method according to claim 1 , wherein said generating the uplink information corresponding to the identification information of the target transmission reception point based on the network configuration information comprises:
performing a logical AND operation on transmission data of an uplink transmission resource corresponding to the target transmission reception point and transmission data of uplink transmission resources corresponding to other transmission reception points, in response to detecting that the uplink transmission resource corresponding to the target transmission reception point and uplink transmission resources corresponding to other transmission reception points overlap; and
taking a result of the logical AND operation as the uplink information.
