Abstract: A spectrum resource determining method includes obtaining sharing information. The sharing information indicates that N first cells and one second cell share a first frequency band, a coverage area of each first cell among the N first cells overlaps a coverage area of the second cell, and N is an integer greater than 1. The method also includes determining a spectrum resource of each first cell among the N first cells in the first frequency band and a first spectrum resource of the second cell. The first spectrum resource is located in the first frequency band, and the first spectrum resource does not overlap the spectrum resource of each first cell among the N first cells in the first frequency band.

Abstract: Example uplink switching methods and apparatus are described. One example method include performing switching between a supplementary uplink (SUL) and a normal (NUL), where a switching time period for the switching between the SUL and the NUL is longer than 0 microseconds. Therefore, the SUL and the NUL can share a radio frequency channel so that the shared radio frequency channel can be switched between the SUL and the NUL.
