Description
Technical field
The present invention relates to the communications field, in particular to a kind of subscriber equipment (User Equipment, referred to as UE), type reports, resource allocation methods and device, UE, base station.
Background technology
In advanced long-term evolution system (Long Term Evolution Advance, referred to as LTE-A), for higher data rate is provided to mobile subscriber, carrier aggregation technology (Carrier Aggregation, referred to as CA) has been proposed.In LTE, the maximum downstream transmission bandwidth of system support is 20MHz, carrier aggregation is that the component carrier of two or more (Component Carriers, referred to as CC) (being called again Serving cell) is aggregating and supports to be greater than 20MHz, and maximum is no more than the transmission bandwidth of 100MHz.In LTE-A system, UE enters and can pass through a plurality of component carriers (also referred to as Serving cell, comprising main Serving cell, auxiliary serving cell) after connected state simultaneously and communicate with source base station.
