Abstract
The present invention provides a dynamic adjustment method of a radio resource block configuration based on a offset, which comprises the following procedures: S102, an offset aggregation is determined according to the radio resource configuration attribute in the radio resource block; S104, one offset is periodically and non-periodically selected from the offset aggregation and the part and the whole radio resource configuration in the radio resource block are changed according to the chosen offset; S106, the transmission data is dispatched according to the changed radio resource block. The change of the sub-carrier configuration in the RB through the technical proposal enables the channel capacity of the sub-channel based on the RB band width in the OFDM system to one or a plurality of receivers to be optimized statistically, thereby improving the transmitted throughput, and in particular to be suitable for a forth mobile communication system.
