Problems solved by technology

[0005] It can be seen from the above that in the existing technical solution for CoMP cell transmission, the UE randomly selects two or three neighboring cells around the UE as candidate CoMP cells. The reception quality of users at the edge of the cell, but because the adjacent cells are randomly selected, there may be adjacent cells with better channel conditions that are not selected as candidate CoMP cells, so that the adjacent cells as CoMP cells are not the most powerful and the relative delay is the smallest adjacent cells, which affects the receiving quality of users at the cell edge and reduces the spectrum efficiency at the edge of the system

Embodiment Construction

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] The method for selecting CoMP cells provided by the present invention clearly defines the conditions for participating in CoMP cells. The UE selects the neighboring cells (ENB) that meet the CoMP cell conditions from the neighboring cells (ENB), and then reports to the main ENB. The primary ENB determines the actual CoMP cell to participate in according to a certain resource configuration strategy. The following takes the selection of an ENB that meets the conditions of the CoMP cell as an example for description.

Abstract

The invention discloses a method for selecting a coordinated multipoint CoMP cell. The method comprises the following steps of: presetting a threshold of the CoMP cell, selecting an ENB which meets the threshold of the CoMP cell as a candidate ENB from an adjacent base station ENB by user equipment (UE), and reporting the ENB to a main ENB. Through the method, the conditions of participating in the CoMP cell are definitely defined, so that the UE selects the ENB which meets the threshold of the CoMP cell from the adjacent ENBs; therefore, the receiving quality of users on the cell edge is optimized, and the spectral efficiency of the system edge is improved.

Description

Technical field [0001] The present invention relates to an evolved version of the LTE-Advanced technology of the Long Term Evolved (LTE), and particularly relates to a method for selecting a Coordinative Multiple Point (CoMP) cell. Background technique [0002] LTE-Advanced technology, as the third generation mobile communication standardization partnership project (3GPP, 3rdGeneration Partnership Project) in the subsequent wireless communication development technology, integrates advanced signal processing technology in the communication field in recent years, for example, orthogonal frequency division multiplexing ( OFDM (Orthogonal Frequency Division Multiplexing) technology, MIMO (Multi-input and Multi-output) technology, adaptive technology, etc., have greatly improved the capacity, spectrum efficiency and coverage of the wireless communication system. [0003] For users in the LTE-Advanced system, in wireless communication, they may be at the center of a cell (sector) or at t...
