Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Those skilled in the art know that the signal level and signal quality of the cell received by the UE can be evaluated by measuring the CSI-RS on the resource of the cell. However, the REs of the CSI-RS are relatively sparse, that is, there are relatively few resources available for measurement within a certain period of time. Therefore, in the embodiment of the present invention, it is proposed to allocate multiple CSI-RS configurations to a cell, and perform...

Abstract

The invention discloses a measuring method and a base station based on a channel-state information-reference signal (CSI-RS), user equipment (UE) and a CSI-RS resource sharing method of a cell. The measuring method comprises the steps that a first base station sends information of at least one CSI-RS configuration collection to the UE, the first base station receives measuring results, on sub-collections or universal collections of corresponding measuring resources of the CSI-RS configuration collection, of the UE, and the CSI-RS configuration collection comprises at least two kinds of CSI-RS configuration. Through the technical scheme about measurement, the fact the CSI-RS is measured on a plurality of CSI-RS configuration is achieved, the problem that resource elements (RE) of the CSI-RS are sparse is solved, and measuring precision of the UE is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular, to a measurement method based on Channel-State Information-reference signal (CSI-RS) resources, a base station, a user equipment UE, and a cell CSI-RS resource sharing method. Background technique [0002] In a wireless communication system, a coordinated multi-point transmission (Coordinated Multi-Point transmission, CoMP) technology is an important means to improve the overall performance of a cell and the performance of users at the cell edge. In a CoMP system, network nodes include an evolved base station (evolved NodeB, eNB) and at least one access point (Access Point, AP), and multiple APs can cooperate to transmit and receive data of a user equipment (User Equipment, UE). These cooperative APs may be in the coverage of the same base station or in the coverage of different base stations. These APs may be, for example, various network nodes, including but no...
