Embodiment Construction

[0029] In order to provide support for three-dimensional channel quality measurement on the terminal side, an embodiment of the present invention provides a method for configuring three-dimensional channel measurement resources.

[0030] See figure 1 , The three-dimensional channel measurement resource configuration method provided by the embodiment of the present invention includes the following steps:

[0031] Step 10: The base station using the two-dimensional array antenna selects channel quality measurement resources for three-dimensional channel measurement from the channel quality measurement resources pre-configured for the terminal; wherein, each channel quality measurement resource corresponds to a time-frequency resource location and at least one Port; here, the time-frequency resource location corresponding to the channel quality measurement resource can be determined by the time-frequency resource location occupied by the channel quality measurement reference signal in ...

Abstract

The embodiment of the invention discloses a three-dimensional channel measurement resource configuration and quality measurement method and equipment, which relate to the field of wireless communication and are used to solve the problem of how to perform three-dimensional channel quality measurement. In the present invention, the base station selects the channel quality measurement resources used for three-dimensional channel measurement from the channel quality measurement resources preconfigured for the terminal, and sends the indication information of the selected channel quality measurement resources to the terminal, and the terminal receives the indication information, and performs corresponding The three-dimensional channel quality measurement is performed on the channel quality measurement resource, thereby solving the problem of how to perform the three-dimensional channel quality measurement.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and equipment for resource configuration and quality measurement of three-dimensional channel measurement. Background technique [0002] With the maturity of active antenna system (AAS) technology, the application of large-scale antennas has become a reality. At present, Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) systems cannot measure the quality of three-dimensional channels. After large-scale antenna applications, the number of ports that the base station can control will increase dramatically to 64 More and more, the application of 3D channels will become more and more extensive. How to effectively measure the quality of the three-dimensional channel is an urgent problem to be solved. [0003] The current system mainly uses cell-specific reference signals (CRS) and channel state information reference signals (CSI reference signals, CSI...
