Abstract

The invention provides a sending method and a receiving method of a CSI-RS sequence, a related device and a system. The sending method comprises the following steps: generating the CSI-RS sequence corresponding to each bandwidth segment in a carrier; and sending the CSI-RS sequence to a user terminal. According to the sending method provided by the invention, the corresponding CSI-RS sequence is configured to each bandwidth segment, thereby solving the CSI-RS configuration problem when different carrier intervals exist in the carrier, and improving the performance of the CSI-RS sequence and the flexibility of system transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for sending and receiving a CSI-RS sequence, related equipment and a system. Background technique [0002] In the current communication system, a channel state information reference signal (Channel State Information Reference Signal, CSI-RS) sequence is configured in the entire carrier, where the length of the CSI-RS is determined by the resource block (Resource Block) contained in the maximum bandwidth that the communication system can support. , RB) depends on the number. [0003] In a future communication system (for example: 5G system), there will be different subcarrier intervals in the same carrier, and the lengths of Orthogonal Frequency Division Multiplexing (OFDM) symbols will be different. Since an RB contains 12 subcarriers, the bandwidth of the RB is different under different subcarrier intervals, and it is difficult for the CSI-RS seque...
