1. A method for measuring channel state information, comprising:
transmitting, by a network device of a serving cell of a user equipment (UE), measurement configuration information of a neighbor cell to the UE, wherein the measurement configuration information is configured to instruct the UE to measure channel state information between the UE and the neighbor cell based on beam transmission, and a measurement result of the channel state information is configured for a network device of the neighbor cell to determine a transmission beam with the UE when the serving cell and the neighbor cell simultaneously transmit data to the UE;
wherein the measurement configuration information comprises first resource indication information of a first reference signal for channel state information signal quality measurement; wherein the first reference signal comprises a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS), transmitted by a network device of the neighbor cell, the first resource indication information comprises a transmission configuration indication (TCI) state; wherein a reference signal indicated by the TCI state comprises an SSB or CSI-RS transmitted by the network device of the neighbor cell through the neighbor cell, or a sounding reference signal (SRS) transmitted by the UE.
