Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] figure 1 is a schematic flow chart of the CoMP implementation method based on beam scanning in the present invention, such as figure 1 As shown, the CoMP implementation method based on beam scanning in the present invention specifically includes the following steps:

[0046] In the CoMP system, it is assumed that the base stations of the serving cell and the cooperating cell are configured with M antennas, and the number of users in the serving cell and the coordinating cell is more than 2 in total, and the same time-frequency resources are configured. For multiple users in two cells, the implementation process of CoMP precoding based on packet beams is described as follows:

[0047] In step 101, a user in a serving cell is selected as a CoMP user.

[0048] In this step, edge users of the serving cell are preferentially sele...

Abstract

The invention discloses a fast, accurate, simple and practical beam-scanning-based coordinated multiple point (CoMP) realization method, which comprises the following steps of: selecting an edge user in a serving cell as a CoMP user; selecting more than one adjacent base station as coordinated base stations; scanning the serving cell and a coordinated cell with the coordinated base station by adopting beams respectively, and computing pre-coding matrixes of a serving base station and the coordinated base stations for the CoMP user according to scanning results and a pre-coding matrix computing formula provided by the invention respectively; and pre-coding signals to be transmitted to the CoMP user and transmitting the pre-coded signals by using the serving base station and the coordinated base stations. The invention correspondingly discloses a beam-scanning-based CoMP realization system, which comprises a CoMP user selection module, a coordinated base station selection module, a beam scanning module and a signal transmission module.

Description

technical field [0001] The present invention belongs to the technical field of wireless communication, and in particular relates to a beam scanning-based CoMP (Coordinated Multiple Point, Coordinated Multiple Point) implementation method and system. Background technique [0002] In the 3GPP (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) long-term evolution (Long Term Evolution-Advanced, LTE-A) system, people pay more and more attention to the average spectrum efficiency of the cell and the spectrum efficiency of the cell edge. In general, the spectral efficiency at the edge of the cell is more concerned, mainly because the uplink and downlink of the LTE-A system are based on OFDM (Orthogonal frequency-division multiplexing)-based multiple access multiplexing. The frequency division system is different from the traditional wireless communication system based on CDMA (Code Division Multiple Access, Code Division Multiple Access), the LTE-A system ...
