Embodiment Construction

[0093] The application will be described in further detail below in conjunction with the accompanying drawings.

[0094] Embodiments of the present application provide a resource configuration method and device for downlink measurement reference signals, which are used to solve the problem in the prior art that resource configuration information overhead for transmission of downlink measurement reference signals by base stations is large. Wherein, the method and the device described in this application are based on the same inventive concept, and since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0095] In this embodiment of the present application, the base station sends the configuration information of the resource pool determined for the preset basic pattern or available resources to the terminal device, so that the terminal device c...

Abstract

The application provides a resource configuration method and device for a downlink measurement reference signal, which is used for solving the problem of high cost for a base station to transmit resource configuration information of the downlink measurement reference signal in the prior art. In the method, the base station can notify terminal equipment a resource pool by configuration informationof the resource pool, which aims at a basic pattern or available resources, resource configuration of the downlink measurement reference signal is implemented, and the resource configuration of the downlink measurement reference signal does not need to be notified to the terminal equipment by a conventional bitmap, and thus, cost for the resource configuration information of the downlink measurement reference signal is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource configuration method and device for downlink measurement reference signals. Background technique [0002] A multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) technology, as a physical layer multi-antenna technology for improving transmission quality and efficiency of a communication system, is widely used in a new generation of communication systems. At present, the Long Term Evolution (LTE) system supports multiple MIMO technologies such as transmit diversity and spatial multiplexing beamforming (Beam Forming, BF), and supports more antenna ports (such as 8, 16, 32 antenna ports). [0003] In order to support the above-mentioned MIMO technology, the pilot signal scheme in the communication system is also adaptively changed. In downlink MIMO in a communication system, downlink pilot signals (or called downlink reference sign...
