Problems solved by technology
However, the actual algorithm used cannot guarantee the uniform utilization of all cells or terminals. If the unit vector of the precoding matrix is too large or too small, the resource investment of the cooperative cell will be too large or too small. After individual terminals are calculated, they cannot be effectively improved. rate, or even the negative effect of reducing the rate

Embodiment Construction
[0055] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0056] refer to figure 1 , shows a flow chart of steps of an embodiment of a method for allocating resources between a serving cell and a coordinating cell in the present invention. Before describing this application, a brief introduction to the CoMP technology is given first.
[0057] 1. Introduction
[0058] LTE has the characteristics of high bandwidth, low delay, and high speed, and is a new development direction of mobile communication. Since LTE uses high bandwidth (up to 20M), the entire network uses the same frequency band, and co-frequency interference becomes the main interference factor of LTE. The biggest challenge faced by LTE is at the edge of the cell. If some coordination is used in the transmission process, the ...

The embodiments of the present invention provide a serving cell and coordination cell resource allocation method and device. The method includes the following steps that: an OMC server acquires a measurement report from one or more base stations according to a preset time interval, wherein the measurement report includes the serving cell quality threshold value of the base station and the coordination cell quality threshold value of the base station; whether the serving cell quality threshold value and the coordination cell quality threshold value satisfy preset conditions are judged; if the serving cell quality threshold value and the coordination cell quality threshold value satisfy the preset conditions, the base station satisfying the preset conditions is determined as a target base station; the resource configuration information of the target base station is acquired; resource allocation information is generated according to the resource configuration information; and the resourceallocation information is sent to the target base station, wherein the target base station is used for performing base station resource allocation according to the resource allocation information. With the serving cell and coordination cell resource allocation method and device provided by the embodiments of the present invention adopted, the performance and overall processing efficiency of the base station can be improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method for allocating resources between a serving cell and a cooperating cell and a device for allocating resources between a serving cell and a cooperating cell. Background technique [0002] CoMP technology is the LTE-Advanced technology released in 3GPP R11. It refers to multiple geographically separated transmission points that cooperate to participate in the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) data transmission of a terminal or jointly receive a PDSCH data sent by the terminal. [0003] It is distinguished according to whether the cell participating in the CoMP process belongs to an eNobeB, CoMP can have two modes: Intra-eNB (belonging to an eNobeB) and Inter-eNB CoMP (not belonging to an eNobeB). The former only needs to exchange CoMP processing related service data and control information among the cells in the base ...
