Abstract

The present invention provides a pilot transmission method and device. The method includes: the transmitting end determines N precoding vectors; the transmitting end generates pilots according to the N precoding vectors; sent to the receiving end, where M and N are both integers greater than or equal to 1. The present invention solves the problem of generating pilots based on deterministic directional precoding codebooks in the related art. Under large-scale antenna arrays, the data of optional beams at the transceiver end increases significantly, and the number of beam combinations at the transceiver end appears The problem of a sharp increase and a sharp increase in pilot overhead can achieve the effect of reducing training costs.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending a pilot. Background technique [0002] As the Institute of Electrical and Electronics Engineers (Institute for Electrical and Electronic Engineers, referred to as IEEE) and the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) continue to develop in the high frequency band (namely millimeter wave communication) High-frequency communication will become an important innovation point of 5G new radio access technology (5G New Radio Access Technology, referred to as 5G New RAT) with its significant advantages of large bandwidth, and is committed to solving the current increasingly congested spectrum resources. The problem of massive access to physical networks has become an important direction for the development of mobile communications in the future. [0003] However, while high-frequency communication has...
