Problems solved by technology

In future new wireless access technology research, eNB can configure different bandwidth parts (BandwidthPart, referred to as BWP) for each user, and the bandwidth part of the user can be larger than the 20MHz bandwidth of the LTE or LTE-A system, while The current SRS bandwidth configuration only supports a maximum of 20MHz, which cannot meet the design requirements of NR

Abstract

The invention provides an information transmission method, which comprises the following steps: a first communication node determines resources or parameters used by a second communication node for sending a reference signal; indicating resources or parameters to the second communication node through signaling; the second communication node receives the signaling sent by the first communication node; according to the signaling, or the signaling and a rule agreed with the first communication node, determining resources or parameters used for sending the reference signal; and sending the reference signal by adopting the determined resource or parameter. In this way, the design requirement for reference signal transmission in the NR system is met.

Description

[0001] This application is a divisional application of the application with the application number 201710939835.7, the application date is September 30, 2017, and the invention name is "a wireless communication method and device". technical field [0002] The present invention relates to the communication field, in particular to an information transmission method and device. Background technique [0003] 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 DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release12 (LTE -A version 12) has added DCI format 2B, 2C, 2D to support a variety of different applications and transmission modes. The base station (e-Node-B, referred to as eNB) can configure the terminal (User Equipment, referr...
