Problems solved by technology

In future new wireless access technology research, eNB can configure different bandwidth parts (Bandwidth Part, referred to as BWP) for each user, and the bandwidth occupied by the user's bandwidth part can be greater than the 20MHz bandwidth of the LTE or LTE-A system. However, the current SRS bandwidth configuration only supports a maximum of 20MHz, which cannot meet the design requirements of NR.

Abstract

The invention discloses an information transmission method, comprising the steps that a first communication node determines a resource or a parameter employed when a second communication node sends areference signal; the resource or the parameter is indicated to the second communication node through a signal; the second communication node receives the signal sent by the first communication node;the resource or the parameter employed for sending the reference signal is determined according to the signal or the signal and a rule appointed by the first communication node; and the reference signal is sent through adoption of the determined resource or parameter. A design demand for transmission of the reference signal in an NR system is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information transmission method and device. Background technique [0002] In Long Term Evolution (LTE for short), a Physical Downlink Control Channel (PDCCH for short) is used to carry uplink and downlink scheduling information and uplink power control information. Downlink Control Information (DCI for short) format (format) is divided into DCIformat 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-ARlease 12 (LTE- A version 12) has added DCI format 2B, 2C, 2D to support a variety of different applications and transmission modes. A base station (e-Node-B, referred to as eNB) can configure a terminal (User Equipment, referred to as UE) through downlink control information, or the terminal accepts configuration from higher layers (higher layers), which is also referred to as configuring the UE through higher layer signaling.
