Embodiment Construction

[0046] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0047] According to an embodiment of the present invention, a CoMP clustering method is provided.

[0048] refer to figure 1 And generally speaking, the method includes: the first step, initializing the CoMP serving base station cluster of each user; Influenced by the local utility of all other users, calculate the decision function value of this user. The second step is performed for each user in all users: change the CoMP serving base station cluster of the user and calculate the new decision function value of the user, if the new decision function value is greater than or equal to the original decision function value, then save the change . The third step is to repeat the second step until the CoMP serving base station clus...

Abstract

The invention provides a CoMP clustering method and an inter-cell resource scheduling method. The CoMP clustering method comprises the first step of initializing a CoMP service base station cluster of each user; for each user, calculating a decision function value of the user according to the local utility of the user and the influence on the local utility of all other users having the same service base station as the user when the user adopts the corresponding CoMP service base station cluster; the second step of executing the operation of modifying the CoMP service base station cluster of the user and calculating the new decision function value of the user for each user among all users, and if the new decision function value is not smaller than the original decision function value, retaining the modification; and the third step of repeating the second step until when the CoMP service base station cluster of the random user is modified, the new decision function value of the user is smaller than the original decision function value. The CoMP clustering method improves the overall throughput of a system, is suitable for being applied to a large-scale network and can support the expandability of the network better.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a CoMP clustering method and an inter-cell resource scheduling method. Background technique [0002] Coordinated Multiple Points transmission / reception (CoMP) is an item proposed in the 4th Generation of Mobile Communication system (4G) Long Term Evolution-Advanced (LTE-A) key technologies. In CoMP, a user terminal (User Equipment, UE) can be jointly served by multiple nearby base stations (called eNode-B, eNB in ​​LTE) at the same time. In this way, the performance of cell-edge users can be improved by performing joint processing of sending and receiving signals among multiple cells. In order to realize CoMP, multiple eNBs need to form a cooperative cluster to perform joint communication with the UE. [0003] Existing clustering methods can be divided into two categories: predefined clustering methods and adaptive clustering methods. In the pr...
