Abstract: The present disclosure relates to wireless communication methods and apparatus. One example method is executed in a communications system including N cells, where at least two cells of the N cells perform wireless communication by using a same carrier set, the carrier set includes M carriers, the M carriers are divided into N time-frequency resource groups, the M time-frequency resources in a same time-frequency resource group are in a one-to-one correspondence with the M carriers, and time domain locations of time-frequency resources corresponding to a same carrier are different, N≥2, and M≥2. The example method includes determining, by a network device, a first time-frequency resource group from the N time-frequency resource groups, and performing, by the network device, wireless communication in a first cell of the N cells by using one or more time-frequency resources in the first time-frequency resource group.

Abstract: A coordinated scheduling method and a related apparatus are disclosed. The embodiments of this application may be applied to multi-frequency ultra-dense networking. The method includes: A base station first determines one or more frequencies corresponding to cells at a capacity layer and one or more frequencies corresponding to cells at a coverage layer. Some cells at the coverage layer are obtained by combining at least two cells having co-channel interference, and cells at the capacity layer are all cells that are not combined. In addition, the base station further obtains network information of the first terminal on at least one carrier set, and optimizes the current network based on the network information.
