摘要： This application discloses a resource scheduling method and apparatus. The method includes: obtaining, by a terminal device, a first resource configuration parameter from an access network device; determining, by the terminal device, whether a first logical channel LCH supports the first resource configuration parameter, where the first LCH is an LCH on which there is to-be-sent data; and if the first LCH supports the first resource configuration parameter, determining, by the terminal device, a resource of the first LCH based on the first resource configuration parameter. According to the resource scheduling method provided in this application, after obtaining the first resource configuration parameter, the terminal device determines the resource of the first LCH by determining whether a mapping relationship exists between the first LCH and the first resource configuration parameter, to map the first LCH to the resource that matches the first LCH. This improves resource utilization.

摘要： Embodiments of the present invention provide an access method, a base station, an access point and a user equipment. The access method includes: a base station sends a first message to an access point through a first communication interface, for requesting the access point to establish a second bearer with a user equipment UE, the second bearer being based on a second communication interface, wherein the first message carries an identifier of the UE and an identifier of an E-RAB; and the base station establishes a first bearer with the access point, the first bearer being based on the first communication interface, wherein the first bearer and the second bearer correspond to the E-RAB. According to the embodiments of the present invention, the first bearer which is based on the first communication interface is established between the access point and the base station, and the second bearer which is based on the second communication interface is established between the access point and the UE, in order to transmit data through the first bearer and the second bearer under the control of the base station, thereby realizing load balance between the base station and the access point.
