Abstract

The invention provides a reference signal configuration, an information sending and information receiving method and device. The reference signal configuration method comprises the following steps: afirst communication node indicates a second communication node to send resource used by a reference signal through a signaling; or both sides of the first communication node and the second communication node pre-define the resource used for sending the reference signal by the second communicate node. The problem that the technical scheme of sending the reference signal in the related technology isimperfect is solved, the sending method of the reference signal is perfected, and the user experience is improved.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for reference signal configuration, information transmission, and information reception. Background technique [0002] In related technologies, 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. The Downlink Control Information (DCI) format is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release 12 (LTE -A version 12) adds DCI format 2B, 2C, 2D to support a variety of different applications and transmission modes. The first communication node (e-Node-B, referred to as eNB) can configure the second communication node equipment (UserEquipment, referred to as UE) through downlink control information, or the second communication node equipment can accept the configuration ...
