Abstract

The invention provides a method and a device for applying reference signal configuration information. The method comprises the steps that: a base station acquires reference signal configuration information, wherein the reference signal configuration information at least comprises one of the following: reference signal configuration information of a local cell, reference signal configuration information of a neighboring cell and reference signal configuration information of a terminal in the neighboring cell; and the base station performs transmission or measurement according to the acquired reference signal configuration information.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an application method and device for reference signal configuration information. Background technique [0002] Currently, the physical layer technology of the New Radio (NR) is under intense discussion in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) RAN1. Compared with the existing LTE, the NR physical layer pursues a more flexible and efficient design goal or purpose. Based on this, a flexible resource configuration method seems to be an important trend, because the resource configuration method supported by the existing LTE cannot flexibly adapt to the dynamic change of the service load. [0003] For LTE FS1, all 10 subframes are used for uplink transmission or all for downlink transmission. This frame structure can only be used in FDD mode. For LTE FS2, each subframe can be used for one of uplink, downlink, and special subframe, and is...
