1. A method, comprising:
receiving virtual bandwidth configuration information comprising a first virtual bandwidth configuration information, wherein the first virtual bandwidth configuration information indicates a first virtual bandwidth in a downlink transmission bandwidth of a serving cell, wherein the first virtual bandwidth is a part or all of the downlink transmission bandwidth of the serving cell; and
performing signal reception on the first virtual bandwidth, wherein the performing signal reception on the first virtual bandwidth comprises receiving a non-zero power channel state information reference signal (NZP CSI-RS) on the first virtual bandwidth, wherein a sequence of the NZP CSI-RS is a truncation of a first sequence, and the sequence of the NZP CSI-RS corresponds to a position of the first virtual bandwidth in the downlink transmission bandwidth, and the first sequence is generated based on a preset formula.
