Configuration and detection method, base station and terminal of a composite tracking reference signal

Abstract

Disclosed are a composite tracking reference signal configuration method, a composite tracking reference signal detecting method, a base station, and a terminal. The composite tracking reference signal configuration method is applicable to a base station and comprises: generating configuration information of a target tracking reference signal; adding, according to the configuration information, the target tracking reference signal to resource elements at different sub-carrier positions and a preset orthogonal frequency division multiplexing (OFDM) symbol position of the target reference signal, or to resource elements at the same sub-carrier position and different OFDM symbol positions to generate a composite tracking reference signal; and sending the composite tracking reference signal to the terminal, wherein the preset OFDM symbol position comprises the OFDM symbol position where the target reference signal is located, or the OFDM symbol position adjacent to the OFDM symbol where the target reference signal is located.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a configuration and detection method of a compound tracking reference signal, a base station and a terminal. Background technique [0002] In the future-oriented fifth-generation (5Generation, 5G) mobile communication system, in order to achieve the goal of a downlink transmission rate of 20Gbps and an uplink transmission rate of 10Gbps, the operating frequency of the communication link is further increased, such as centimeter wave and millimeter wave, etc. . [0003] On the one hand, high-frequency bands have more abundant spectrum resources, which can provide wider bandwidths to achieve higher transmission rates. But on the one hand, high-frequency transmission also has its own unique problems: more serious phase noise, larger Doppler (Doppler) expansion, larger frequency offset, etc., and also put forward higher requirements for communication equipment componen...
