## Abstract

A method for configuring a frame structure, a network side device and a terminal are provided. A relevant frame structure is modified so that uplink and downlink transmission resources are flexibly adjusted, so as to be adapted to requirements of uplink and downlink services and not be limited to a certain type or certain types of fixed uplink and downlink configurations and GP configurations. The method includes determining a first period and first indication information, wherein the first period is a frame period configured for a carrier or a period in which a uplink transmission appears; the first indication information is used to indicate whether a time-domain transmission resource available for the uplink transmission exists in the first period or not; and, if the time-domain transmission resource exists, indicate a position of the time-domain transmission resource.
