Abstract: A graph refactorization method is provided, and relate to the field of communication technologies, to implement parallel graph processing with load balancing, low communication costs, and short execution time. The method includes: A first machine selects a first vertex from a local vertex set of a subgraph (S801). If a degree of the first vertex is less than or equal to a first preset threshold, the first machine fuses the first vertex and an adjacent vertex within a preset quantity of hops of the first vertex in the local vertex set into a super-vertex (S802). If the degree of the first vertex is greater than or equal to a second preset threshold, the first machine copies the first vertex to obtain N sub-vertices, and divides edges of the first vertex in the subgraph of the first machine into N parts to respectively connect to the N sub-vertices (S803).

Abstract: Embodiments of the present application provide a channel state information feedback method, device, and system. The method includes: generating an uplink signal, where the uplink signal carries information for identifying multiple codewords and weights of the codewords; and transmitting the uplink signal to a base station (BS), so that the base station estimates a downlink channel based on the multiple codewords and weight information of the codewords in the uplink signal. In the embodiments of the present application, a user equipment UE side reports multiple codewords and weight information of the multiple codewords. This can resolve a problem in the prior art that precision of downlink channel estimation performed by a BS side is relatively low because only a single codeword is reported, and can effectively enhance precision indicated by channel information, without increasing complexity of a codebook design and implementation.
