Abstract: Provided is a reference signal transmission method and device. The method includes that a base station transmits indication information to a UE through a downlink control signaling or a higher layer signaling, where the indication information includes one of: information indicating that the UE transmits a reference signal, information indicating whether the reference signal is contained in a physical downlink shared channel or a physical downlink control channel, or information indicating a transmission mode of a downlink reference signal or an uplink reference signal; or the base station pre-defines with the UE a time-frequency resource or a parameter set required by the UE or the base station to transmit the reference signal, where the time-frequency resource or the parameter set includes at least one of: a time domain symbol position, a frequency domain position, a transmission period and a subframe offset, a type of a reference signal sequence or an orthogonal mask. This solves the problem in the existing art of how to properly place a reference signal on time-frequency resources and trigger a signaling correspondingly.

Abstract: Disclosed are an inter-carrier frequency cooperation method and device. According to the method, description information of a second carrier frequency is determined and a communication node sends the description information of the second carrier frequency to a second communication node via a first carrier frequency. The description information of the second carrier frequency includes one of: sending beam information of the second carrier frequency, pilot information of the second carrier frequency, control channel information of the second carrier frequency, data channel information of the second carrier frequency, Hybrid Automatic Repeat Request (HARQ) timing information of the second carrier frequency and working time information of the second communication node on the second carrier frequency.
