The present invention provides a method and an apparatus for transmitting an uplink signal, where the method includes: receiving information that is of a network resource and sent by a scheduling cell, where the scheduling cell is a neighboring cell of a serving cell to which the user equipment belongs; and sending the information of the network resource to the user equipment, so that the user equipment sends the uplink signal by using the network resource. In the method and apparatus for transmitting an uplink signal according to embodiments, the uplink signal is sent by allocating the user equipment with the network resource of the scheduling cell with a small power loss, thereby ensuring quality of the uplink signal as far as possible.
