Abstract

Embodiments of the present invention provide a method, an apparatus, and a base station for resource allocation, where the method includes: receiving, by a network side device, a measurement report sent by a UE; acquiring, by the network side device, RSRP1 and RSRP2 from the measurement report, where the RSRP1 is RSRP from the UE to a serving cell and the RSRP2 is RSRP from the UE to a neighboring cell; determining, by the network side device according to an absolute value of the RSRP1, an absolute value of the RSRP2, a difference between values of the RSRP1 and the RSRP2, a frequency band that is suitable to be used by the UE, where the frequency band includes: a central frequency band and an edge frequency band; and allocating, by the network side device according to a result of the determining, a resource for the UE on the frequency band that accords with the result of the determining. In the embodiments of the present invention, a network side device determines, not only according to a difference between values of RSRP1 and RSRP2 but also according to an absolute value of the RSRP1 and an absolute value of the RSRP2, a frequency band that is suitable to be used by a UE, and allocates a resource for the UE on the suitable frequency band, so that coverage performance of a cell can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource allocation method, device and base station. Background technique [0002] At present, LTE (Long terms evolution, long-term evolution), the fourth-generation mobile communication standard promoted by 3GPP, has won the support of most operators around the world due to its high peak rate, high spectrum efficiency, and low delay. LTE adopts OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) as its multiple access mode, and obtains high spectral efficiency, but inter-cell interference becomes the main factor affecting its performance when LTE is in the same frequency network. In order to control inter-cell interference, an ICIC (inter-cell interference coordination, inter-cell interference coordination) technology is used in the LTE system to manage inter-cell interference. ICIC uses ...
