Networking method, networking apparatus, network access method, and user equipment for coordinated multiple points transmission/reception

A networking apparatus, comprising:

• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions cause the at least one processor to:
• determine a network association relationship between each remote radio unit (RRU) and each user equipment (UE) for all RRUs and all UEs managed by a baseband processing unit (BBU) resource pool, wherein the network association relationship comprises whether the RRU is capable of providing a service for the UE, or a relationship between the UE and the RRU represented by a reference signal received power that corresponds to each RRU and that is reported by the UE;
• and
• configure all the RRUs to M subnets based on the network association relationship between each RRU and each UE, wherein M≥1, and M is less than a quantity of all the RRUs, wherein configuring all the RRUs to M subnets based on the network association relationship between each RRU and each UE comprises:
• establishing a current relational matrix of the BBU resource pool based on the network association relationship between each RRU and each UE, wherein a quantity of rows in the current relational matrix is a quantity of all the UEs, a quantity of columns in the current relational matrix is a quantity of all the RRUs, and an element in the current relational matrix represents a network association relationship between an RRU and UE that corresponds to a location at which the element is located;
• calculating a Laplacian matrix of the current relational matrix and all eigenvectors of the Laplacian matrix;
• clustering, according to a clustering algorithm and based on the all eigenvectors of the Laplacian matrix, RRUs and UEs corresponding to elements in the current relational matrix to generate a clustering result;
• and
• configuring all the RRUs to M subnets based on the clustering result,
• wherein if the network association relationship is whether the RRU is capable of providing a service for the UE, determining the network association relationship between each RRU and each UE for all the RRUs and all the UEs managed by the BBU resource pool comprises:
• obtaining an identifier of each RRU corresponding to the reference signal received power that is measured and reported by each UE;
• determining, based on the identifier of each RRU corresponding to the reference signal received power that is measured and reported by each UE, an RRU that is capable of providing a service for the UEs managed by the BBU resource pool;
• and
• determining, based on the RRU that is capable of providing the service for the UEs managed by the BBU resource pool, the network association relationship between each RRU and each UE for all the RRUs and all the UEs managed by the BBU resource pool.
