Abstract: Embodiments of the present invention provide an access method and system, a user equipment, and a network side device. The method includes: receiving, by a user equipment, a first message that carries an identifier of a second network access point, where the second network access point can perform air interface offloading on a first network in which a user equipment is currently located; and when the first message carries identifiers of a plurality of second network access points, selecting, by the user equipment, one second network access point from the plurality of second network access points according to first auxiliary information, and accessing the selected second network access point. By adopting the technical solutions in the embodiments of the present invention, an access delay can be effectively shortened, and access efficiency can improved, thereby effectively implementing offloading.

Abstract: Disclosed are an adaptive frequency domain resource configuration method, an apparatus, and a communications system. The method includes receiving, by a receiving apparatus, a pilot signal transmitted by a transmitting apparatus and feeding back channel information of a channel for transmitting the pilot signal to the transmitting apparatus by measuring the pilot signal, so that the transmitting apparatus divides a bandwidth frequency of the transmitting apparatus according to the channel information. The receiving apparatus can feed back the channel information to the transmitting apparatus according to the received pilot signal, so that the transmitting apparatus can divide the bandwidth frequency according to channel quality, and adaptive adjustment can be performed on a frequency domain resource of each subcarrier according to the channel information fed back by the receiving apparatus.
