Abstract:
1. A Long Term Evolution (LTE) downlink control channel resource allocation method, comprising: sending, by a base station, resource scheduling information to a physical layer via a Media Access Control (MAC) layer; determining a search space to which resources to be allocated belong according to the resource scheduling information; and allocating the resources of a current downlink channel according to a quality level of the current downlink channel, when the resources to be allocated belong to a dedicated search space of a User Equipment (UE); wherein allocating the resources of the current downlink channel according to the quality level of the current downlink channel comprises: if the quality level of the current downlink channel is a first predetermined level, setting a current CCE allocation value of the current downlink channel in a manner of decreasing progressively in preset time to allocate the resources, based on a CCE allocation value to which the quality level of the current downlink channel corresponds, wherein the current CCE allocation value is greater than or equal to the minimum threshold; and if the quality level of the current downlink channel is a second predetermined level, setting the current CCE allocation value of the current downlink channel in a manner of increasing progressively in preset time to allocate the resources, based on a default CCE allocation value of the dedicated search space of the UE or the CCE allocation value to which the quality level of the current downlink channel corresponds, wherein the current CCE allocation value is less than or equal to the maximum threshold.
