1. A method for transmitting parameters, comprising:
- determining, by a transmission node, a first set of parameters, which comprises at least one antenna port number, the number of total layers, and a frequency index of a Physical Downlink Shared Channel (PDSCH) for downlink transmission, for the transmission node, wherein the first set of parameters is configured for generating at least one user equipment (UE) specific reference signal; and
sending, by the transmission node, the first set of parameters to one or more transmission nodes adjacent to the transmission node;
selecting, by the one or more transmission nodes, a second set of parameters, which comprises at least one antenna port number, the number of total layers, and a frequency index of a Physical Downlink Shared Channel (PDSCH) for downlink transmission, according to the first set of parameters, wherein a value corresponding to at least one of the second set of parameters is different from values corresponding to the first set of parameters;
generating, by the one or more transmission nodes, at least one UE specific reference signal corresponding to the one or more transmission nodes according to the second set of parameters.

Abstract
Disclosed are a method and device for transmitting parameters and a method and device for generating parameters. The method for transmitting parameters comprises: a transmission node determines a first set of parameters for the transmission node to generate at least one user equipment specific reference signal; and the transmission node sends the first set of parameters to one or more transmission nodes adjacent to the transmission node. Through the disclosure, interference between user equipment specific reference signals of transmission nodes is reduced.
