Resource distribution method and eNodeB (evolved Node B)

Abstract

Disclosed is a method for allocating resources, the method comprising the following steps: upon a determination to start adjustment of the proportion value of an uplink and downlink Control Channel Element (CCE), on the basis of an uplink and downlink CCE proportion adjustment strategy, the uplink and downlink CCE proportion is adjusted by using the uplink CCE utilization rate and a downlink CCE utilization rate of an ordinary sub-frame; and upon a determination to start adjustment of a Control Format Indicator (CFI) value, on the basis of a CFI adjustment strategy, the CFI value is adjusted by using the average CCE utilization rate and the average Resource Block (RB) utilization rate of the ordinary sub-frame. Also disclosed is an evolved Node B (eNodeB). With the present invention, the resources may be scheduled flexibly on the basis of the current system operation status, thus, the resources utilization rate is optimized, and then the system performance is improved.

Description

technical field [0001] The present invention relates to a resource allocation technology in a Long Term Evolution (LTE, Long Term Evolution) system in the field of wireless communication, in particular to a method for allocating resources and an evolved base station (eNodeB). Background technique [0002] The LTE project in the 3rd Generation Partnership Project (3GPP, The 3rd Generation Partnership Project) in the field of wireless communication is the evolution of 3G, which improves and enhances the air access technology of 3G, and adopts Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) / Frequency Division Multiple Access (FDMA, Frequency Division Multiple Access) as the core technology. [0003] In the LTE system, uplink / downlink transmission information can be divided into two categories: service information and control information. Among them, the service channel used in the transmission of service information uses resource b...

Problems solved by technology

[0005] However, in the method for allocating resources by the eNodeB above, since the parameters used in calculating the CFI value are not variable, and the uplink and downlink CCE ratios are not variable, the CFI value of each subframe remains unchanged and is allocated to the uplink / downlink control channel respectively. The resources remain unchanged, so the resources occupied by the control channel cannot be adjusted according to the current system operating status. In this way, a large amount of resources may be allocated to the uplink control channel or downlink control channel that does not need to use a large amount of resources, thereby affecting resource utilization.

[0006] It can be seen that the existing eNodeB resource allocation methods cannot flexibly schedule resources according to the current system operating status, so that resource utilization cannot be optimized, and system performance cannot be improved.
