Abstract: Disclosed are a pilot configuration method and an apparatus. The method includes: before allocating a pilot to a first user, determining, by a base station, interference between the first user and a second user if the base station allocates a pilot of the second user to the first user; if the interference between the first user and the second user is less than a preset threshold, the pilot allocated by the base station to the first user is the same as a pilot used by the second user; or if the interference between the first user and the second user is greater than or equal to the preset threshold, the pilot allocated by the base station to the first user is different from the pilot used by the second user.

Abstract: This application provides an example signal transmission method and device. The method includes receiving, by a second node, a first signal sent by a first node, where the first signal includes information about a time resource that needs to be occupied by the first node to perform backhaul transmission, and a receiving/sending status of the first node during the backhaul transmission. The method also includes, when the receiving/sending status of the first node during the backhaul transmission is different from a receiving/sending status of the second node during backhaul transmission, receiving/sending, by the second node, a signal on a resource other than the time resource that needs to be occupied by the first node to perform the backhaul transmission.
