Problems solved by technology

[0003] Because in the same cell or sector, when the PTRS sequences adopted by multiple terminal devices are the same, the frequency domain positions of the PTRS mapped by the multiple terminal devices through the same PTRS port are all the same. Different PTRS on the network will interfere with each other, thus affecting the estimation of phase noise, how to randomize the interference of PTRS becomes an urgent problem to be solved

Abstract

The invention provides a transmission method and device for a reference signal. The transmission method comprises the steps that network equipment determines the resource block offset of the frequencydomain location of a PTRS (Phase Tracking Reference Signal) of terminal equipment according to phase tracking reference signal (PTRS) information of the terminal equipment, identification of the terminal equipment and first bandwidth, wherein the PTRS information includes the frequency domain density or the frequency domain interval of the PTRS, and the first bandwidth is the bandwidth scheduledby the network equipment for the terminal equipment; and the network equipment transmits the PTRS with the terminal equipment according to the resource block offset of the frequency domain location ofthe PTRS. The transmission method provided by the embodiment of the invention for the reference signal is conducive to randomizing the interference of the PTRS.

Description

Technical field [0001] This application relates to the communication field, and more specifically, to a transmission method and transmission device of a reference signal in the communication field. Background technique [0002] With the development of network systems, the demand for communication speed and capacity has increased, and the demand for high-frequency resources has also increased. However, as the frequency increases, the phase noise generated by the random jitter of the frequency device, the local oscillator, also increases. Therefore, the influence of phase noise in high-frequency wireless communication cannot be ignored. Normally, the transmitting end equipment can add a pre-known phase tracking reference signal (PTRS), and the receiving end can be The received PTRS estimates the phase noise. [0003] Since in the same cell or sector, when multiple terminal devices adopt the same PTRS sequence, the PTRS mapped by the multiple terminal devices through the same PTRS po...
