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

A wireless communication method, comprising: a first communication node determines resources or parameters used by a second communication node to send a reference signal; indicates the resources or parameters to the second communication node through signaling; the second communication node receives the information sent by the first communication node signaling; according to the signaling, or the signaling and the rules agreed with the first communication node, determine resources or parameters used for sending the reference signal; use the determined resources or parameters to send the reference signal. In this way, the design requirement for reference signal transmission in the NR system is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless communication 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-A Release 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. [0003] A measurement reference s...
