Abstract: This disclosure belongs to the field of communication technologies, and provides a network chip management method and apparatus, a communication device, and a storage medium. According to the network chip management method provided in this disclosure, an idle target network chip is determined based on at least one of a port status, a configuration status, and a traffic status of a network chip; and a first functional module in the target network chip is controlled to run at a sleep running frequency, so that power consumption of the target network chip can be effectively reduced.

Abstract: Disclosed are a distributed multi-cell multi-user beamforming method, a transmitter and a relevant system. In the distributed beamforming method in the embodiments of the present invention, beamforming coordinated calculation is performed by a plurality of transmitters, and an interference matrix among the transmitters is used to perform an iterative operation on a beamforming vector corresponding to the data which is to be sent to each user over each sub-channel of this cell, so that the interference dimension of each user over each sub-channel of the transmitters is compressed into a subspace as small as possible.
