Auxiliary carrier adding method and device and electronic equipment

The invention provides an auxiliary carrier adding method and device and electronic equipment, and relates to the technical field of wireless communication. The auxiliary carrier adding method comprises the steps that firstly, a first base station can respond to a measurement report (MR) sent by first user equipment, the strongest first neighbor cell and the interference value of each resource block (RB) in the strongest first neighbor cell are determined, and the strongest first neighbor cell is the neighbor cell with the strongest reference signal receiving power (RSRP); and then, after the first base station determines the strongest non-full-band interference of the first neighbor cell according to the interference value of each RB, the first base station can determine an optimal RB group from each RB. Finally, the first base station may allocate carrier resources for the first user equipment based on the optimal RB group. Therefore, on the basis of ensuring the good RSRP, the channel quality is considered
